BACKGROUND:

	All seven commodities in the current Crop Group 11, Pome fruits Group
in 40 CFR 180.41 are members of the Rosaceae or Rose botanical family. 
Apple and pear were selected as representative commodities for this
group.  The crop group regulation for Pome Fruits Group has facilitated
establishment of 47 group tolerances on pome fruits.  

It is interesting to view the production data for some pome fruits from
FAO agriculture statistics.  The world total acreage for apples, pears,
and quinces decreased from 7,817,276 hectare in 1995 to 6,681,092
hectare in 2005, however the total production of these fruits has
increased from 63,428,802 metric tons in 1995 to 834,719,870 metric tons
in 2005 (FAO 2005; Table 6).  Some “minor” pome fruits commodities
have become more popular in some countries and areas today than they
were 10 years ago, such as crabapples, mayhaw, and the “orphan”
crops medlar and tejocote.  Some of these fruits don’t have large
commercial production, and thus have little chance to be added to pest
control products labels unless they are placed in the pome fruit group. 
Some of these “minor” pome fruits have great potential to be grown
on a larger scale in some areas in the future due to their unique
nutritional and medicinal values, such as mayhaw.  Mayhaw contains the
highest red pigment and pectin among fruits, which give it a natural
food color and texture for jelly and its vitamin and mineral components
are also among the highest of the fruits, and the vitamin C content is
next to dates and kiwifruit and is 18 times higher than apple.  In a
news release in 2005, it was reported that mayhaws were growing in
popularity in Louisiana, where production was almost doubled in 2004. 
USDA CSREES Newsroom reported last year that the farm gate value of
Louisiana mayhaw production increased from less than $200 in 1992 to
$123,678 in 2004, and the market value for orchard mayhaw products last
year was more than $500,000.  Currently mayhaw has not been included in
either Codex or EU pome fruits group, but there is relatively larger
commercial mayhaw production in some countries such as China.  It will
benefit growers and consumers if this commodity is also added to both
the Codex and the EU groups.  The “orphan” crops medlar and tejocote
were not included in the existing U.S. EPA pome fruits group, but they
are listed in both Codex and EU pome fruits groups.  Adding these two
commodities in the EPA pome fruits group will help our effort in
harmonizing with the Codex and EU crop classification systems.  Being
excluded from the crop groups, tolerances requested for these
commodities would have to be established based on separate residue
studies.  Without a doubt the inclusion of these commodities in crop
groups will benefit growers, consumers, save time and tax payer’s
money on residue studies, save government agencies time in review
residue data, as well as facilitating the establishment of import
tolerances. 

This petition proposes “Pome fruits Group 11” with 10 commodity
entries in the genera Malus, Eriobotrya, Chaenomeles, Crataegus,
Mespilus, Pseudocydonia, Pyrus and Cydonia, which are all in the
Rosaceae botanical family.  Compared to the many other crop groups,
commodities in this group are all closely related since they are all in
the same family and especially share similar morphological and cultural
characteristics.  The 10 commodities in the proposed crop group are
temperate season perennial trees grown for edible fruits.  The fact that
these fruits are in the same botanical family with similar biological
and cultural aspects suggests they should also encounter similar pest
problems and hence have similar needs for pest control products in
similar use patterns.  Commodities and their varieties and/or hybrids
proposed in this group will include all the commodities in the Codex
Classification of Pome Fruits Group and EU Crop List of Pome Fruits
Group. 

The Crop Group 11 proposal was generated at the USDA/IR-4 Crop Grouping
Symposium in Washington, DC, October 2002 by the Temperate Tree and
Small Fruit Workgroup Chaired by Van Starner of USDA, IR-4 and
Co-Chaired by Craig Hunter, Canadian Horticultural Center, Rick
Melnicoe, University of California Department of Environmental
Toxicology, Dr. Richard Loranger and Chris Olinger, EPA, HED and John
Wise, Michigan State University.  It was further discussed and developed
within the pome fruits Workgroup of the ICGCC.  This workgroup consists
of over 200 crop or regulatory experts from the US, and NAFTA, EU, Asia,
Middle East, and Latin America Regions representing over 40 countries. 
The Workgroup discussed and validated each of the proposed commodities
and representative commodities.  Representative commodities in the
existing EPA Pome Fruits Group, apple and pear, have been recommended by
the Workgroup to be representative commodities for the proposed amended
group.  Another important aspect is the harmonization with the Codex
crop classification.  The Codex Classification of foods and animal feeds
for Pome Fruit Group is also undergoing revision.  The IR-4/EPA Crop
Grouping Working Group and the International Crop Grouping Consulting
Committee (ICGCC) are making every effort to collaborate with the
revision of the Codex crop classification.  The expanded Pome Fruit
Group and the representative commodities proposed in this petition would
facilitate the harmonization of the U.S. and the Codex crop
classification systems.  

HED RECOMMENDATIONS:

	Each of the proposals and recommendations will be discussed below,
followed by a series of other recommendations on terminology, database
development, and harmonization with Codex.  The EPA would like to
commend the valuable and high quality input of the ICGCC, all its
members, and the Committee Chairperson Dr Hong Chen and Bill Barney,
USDA IR-4, as well as Dr. Yuen-Shaung Ng, Biologist, HED, Jessie
Cordova, HED Information Technical Specialist, Susan Stanton, Roger
Chesser and Laura Nollen, Biologists, RD, EPA for their input and
development of various databases in this report and Dr. Paul Schwartz,
USDA, Office of Minor Use Pesticides for his advice and peer review.

IR-4 Proposal 1:

1. “Amend the existing crop group in 40 CFR 180.41 (c) (11) that
consists of the following seven commodity entries:

Apple, Malus domestica Borkh.

Crabapple, Malus spp.

Loquat, Eriobotrya japonica (Thunb.) Lindl.

Mayhaw, Crataegus spp.

Pear, Pyrus communis L. 

Pear, oriental, Pyrus communis L.

Quince, Cydonia oblonga Mill.

To an expanded crop group that consists of the following 10 commodity
entries:

Apple, Malus domestica Borkh. (Rosaceae)

Crabapple, Malus  spp. (Rosaceae) (Chinese apple, Chinese crabapple,
Chinese flowering Apple, Crabapple, Cutleaf crabapple, Florentine
crabapple, Hall crabapple, Iowa crabapple, Japanese crabapple, Kai do
crabapple, Manchurian crabapple, Paradise apple, Sargent's crabapple,
Siberian crabapple, Soulard crabapple, Southern crabapple, Sweet
crabapple, Tea crabapple, Toringa crabapple, Western Crabapple, Yunnan
crabapple, and varieties and/or hybrids of these)

Loquat, Eriobotrya japonica (Thunb.) Lindl. (Rosaceae)

Mayhaw, Crataegus spp. (Rosaceae)

Medlar, Mespilus germanica L. (Rosaceae)

Pear, Pyrus communis L. (Rosaceae)

Pear, Oriental, Pyrus communis L. (Rosaceae)

Quince, Cydonia oblonga Mill. (Rosaceae)

Quince, Chinese, Chaenomeles speciosa (Sweet) Nakai (Rosaceae)

Tejocote, Crataegus pubescens (Rosaceae)

And all varieties and/or hybrids of these.” 

HED Recommendation for Proposal 1:

	Based on similarities and characteristics of the Roseaceae or Rose
family which includes all the proposed members to the Pome Fruit Crop
Group 11, as well as a comparison of pome fruits, cultural practices,
edible food and animal feed portions, residue levels, geographical
location, pest problems, established tolerances, and for international
harmonization purposes, I recommend that ChemSAC concur to amend the
Pome Fruit Crop Group 11 from seven commodities to twelve commodities.

	While USDA IR-4 submitted a amended crop group with three new
commodities (Medlar, Chinese quince, and Tejocote), further research and
International comments provided supporting data to add an additional two
commodities (Azarole and Japanese quince) to the group.  In addition to
Chinese quince, we recommend to add Japanese quince to the list of
commodities, since they are distinct crops in that growing regions and
fruit size are different.  There were no crop subgroups proposed by IR-4
or recommended for this crop group.

	The scientific names of the twelve commodities were also updated and
are listed below.  

“HED Corrected Proposed Pome Fruit Crop Group 11 - 09”.

Commodities

Apple, Malus domestica Borkh.

Azarole, Crataegus azarolus L.

Crabapple, Malus sylvestris (L.) Mill., Malus prunifolia (Willd.) Borkh.

Loquat, Eriobotrya japonica (Thunb.) Lindl.

Mayhaw, Crataegus aestivalis (Walter) Torr. & Gray, C. opaca Hook. &
Arn., and C. rufula Sarg.

Medlar, Mespilus germanica L.

Pear, Pyrus communis L

Pear, Asian, Pyrus pyrifolia (Burm. f.) Nakai var. culta (Makino) Nakai 

Quince, Cydonia oblonga Mill.

Quince, Chinese, Chaenomeles speciosa (Sweet) Naka, Pseudocydonia
sinensis (Thouin) C.K. Schneid.

Quince, Japanese, Chaenomeles japonica (Thunb.) Lindl. Ex Spach

Tejocote, Crataegus mexicana DC.

Cultivars, varieties and/or hybrids of those above commodities 

	Additional notes: 

HED also recommends that crabapple not include all the others common
names associated with the crop as was proposed.  These terms will be
included in the Food and Feed Commodity Vocabulary as lookup terms and
crabapple will be the preferred commodity name.  

HED also recommends changing the preferred commodity name for Oriental
pear to Asian pear, since Asian pear has become the prefer commodity
name in the marketplace trade and in grocery stores.

HED also recommends that in the crop group table the term “varieties
and/or hybrids of these” should be changed to, “varieties, cultivars
and hybrids, of these commodities” to avoid all confusion with
terminology regarding whether they are varieties, cultivars, or hybrids
of the any pome fruit commodities.

IR-4 Proposal 2:

2. “Retain the current commodities, Apple, and Pear, as representative
commodities also for the proposed expanded group.”

HED Recommendation for Proposal 2:

	I recommend ChemSAC concur to retain apple and pear as the
representative commodities for the amended Pome Fruit Crop Group 11. 
These two representative commodities account for > 99 % of the harvested
acres for the members of the amended Pome Fruit Group.  The
representative commodities are based on similarities in fruit and
cultural practices and geographical locations, as well as their high
production (both acres and yield) and consumption.  A comparison of
established tolerances on pome fruit commodities also supports that
residue levels will be similar between members of the crop group.

IR-4 Proposal 3:

“A commodity definition for Crabapples will need to be established in
40 CFR 180.1 (g) to list all the types of crabapples such as Crabapples,
Malus  spp. (Rosaceae) (Chinese apple, Chinese crabapple, Chinese
flowering Apple, Crabapple, Cutleaf crabapple, Florentine crab apple,
Hall crabapple, Iowa crabapple, Japanese crabapple, Kai do crabapple,
Manchurian crabapple, Paradise apple, Sargent's crabapple, Siberian
crabapple, Soulard crabapple, Southern crabapple, Sweet crabapple, Tea
crabapple, Toringa crabapple, Western Crabapple, Yunnan crabapple, and
varieties and/or hybrids of these).”

HED Recommendation for Proposal 3 Commodity Definition for Crabapple:

	I recommend rejecting the Crabapple commodity definition under 40 CFR
Part 180.1(h) because these crabapples will be listed in the EPA Food
and Feed Commodity Vocabulary (http://www.epa.gov/pesticides/foodfeed)
as lookup terms and the preferred term for all of them will be
crabapple.

Additional HED Recommendations/Conclusions:

HED Recommendation 4:

	Another important aspect of crop grouping is the harmonization effort
with the Codex Classification of Foods and Animal Feeds.  The current
EPA crop group for Pome fruit group 11 is similar to the corresponding
Codex Pome fruits (Crop Group 002).  The Codex Group 002, Pome Fruits,
consists of eleven commodities including six of the seven commodities in
the current EPA crop group 8.  The only exceptions are mayhaw which is
in the U.S. crop grouping system and medlar which is in the Codex
system.  The U.S. Crop group is also proposing to add three new
commodities: azarole, Chinese quince, and tejocote that are not yet in
the Codex classification system.  EPA will change the name of the
commodity Oriental pear to Asian pear based on the international usage
of Asian pear as a trade name for this commodity.  The eleven Codex
commodities really consist of seven distinct commodities with the rest
being multiple entries, or varieties of cultivar of other commodities
listed.  The scientific name for Oriental pear in the Codex system is
incorrect Pyrus pyritolia should be Pyrus pyrifolia (Burm. f.) Nakai
var. culta (Makino) Nakai and the scientific name for pear should be
Pyrus communis L. not Pyrus pyrifolia.  Note that the current Codex crop
group does not have representative commodities.  A revision of the Codex
Classification is underway with consideration to include adding new
commodities, creating subgroups, and selecting representative
commodities.  

HED Recommendation 5:

Guidance for HED SOP 99.6 -  SEQ CHAPTER \h \r 1  “Classification of
Food Forms with Respect to Level of Blending” issued August 20, 1999,
and HED SOP 2000.1 – “  SEQ CHAPTER \h \r 1 Guidance for Translation
of Field Trial Data from Representative Commodities in the Crop Group
Regulation to Other Commodities in Each Crop Group/Subgroup” issued
September 12, 2000 can be updated to reflect the amendment to the Pome
fruit group 11.

HED Recommendation 6:

Guidance on expressing tolerance terminology for the Pome fruit crop
group 11 is discussed under the “Tolerance expression guidance section
of this analysis.

HED Recommendation 7:

	The Health Effects Division Dry Matter and Seeding Rate Database
prepared by Dr’s. Yuen-Shaung NG and B. A. Schneider, was updated on
September, 2008 in Table 44 for the Pome Fruit Group.

HED Recommendation 8: 

New lookup and preferred EPA terms for the members of the Pome Fruit
Crop Group are listed in the EPA Food and Feed Commodity Vocabulary
section of this report and these terms should be added to the updated
EPA Food and Feed Commodity Vocabulary website
(http://www.epa.gov/pesticides/foodfeed). 

ANALYSIS OF THE USDA IR-4 PROPOSAL TO ESTABLISH AN AMENDED POME FUIT
GROUP 10

BOTANICAL CHARACTERISTICS OF PROPOSED COMMODITIES:

	Pome fruits are all members of the family Rosaceae.  The family
Rosaceae or Rose family has four subfamilies of which the pome fruits
are contained in the Maloideae subfamily.  This petition proposes
“Pome fruits Group 11” with 10 commodity entries in the genera
Malus, Chaenomeles, Crataegus, Cydonia, Eriobotrya, Mespilus, and Pyrus,
all in the same Rosaceae botanical family.  Compared to the many other
crop groups, commodities in this group are all closely related since
they are all in the same family/subfamily and share similar
morphological, cultural characteristics, and pest problems.  There are
over 100 genera and over three thousand species in the Rosaceae family. 
The greatest diversity of members of the Rosaceae is in Europe, Asia, or
North America.  The family includes some of the most well-known garden
trees and shrubs, including the rose, cotoneaster, pyracantha, geums,
kerria, and British native species such as hawthorn and rowan.  The
family also includes many fruits of temperate regions, including apple,
pear, cherry, plum, peach, raspberry and strawberry.

	While there are many different types of   HYPERLINK
"http://science.jrank.org/pages/2878/Fruits.html"  fruits  in the rose
family, ranging from single-seeded, soft, fleshy, fruits known as drupes
to harder, fleshy pseudocarps such as a pome or hip.  In the genera
Malus (apples and crabapples), Chaenomeles, and Rosa, the true fruit is
engulfed in a fleshy structure called the hypanthium, which is composed
of the swollen stem or base of petals and sepals.  In the mature
pseudocarp (pome), the true fruit is centrally located and contains five
distinct carpels which may contain one or more   HYPERLINK
"http://science.jrank.org/pages/6061/Seeds.html"  seeds  each.  The
fleshy   HYPERLINK "http://science.jrank.org/pages/6847/Tissue.html" 
tissue  which surrounds the fruit is the hypanthium.  A pome is an  
HYPERLINK "http://en.wikipedia.org/wiki/Accessory_fruit" \o "Accessory
fruit"  accessory fruit  composed of five or more   HYPERLINK
"http://en.wikipedia.org/wiki/Carpel" \o "Carpel"  carpels  in which the
  HYPERLINK "http://en.wikipedia.org/wiki/Exocarp" \o "Exocarp"  exocarp
 forms an inconspicuous layer.  The   HYPERLINK
"http://en.wikipedia.org/wiki/Mesocarp" \o "Mesocarp"  mesocarp  is
usually fleshy, and the   HYPERLINK
"http://en.wikipedia.org/wiki/Endocarp" \o "Endocarp"  endocarp  forms a
leathery case around the   HYPERLINK "http://en.wikipedia.org/wiki/Seed"
\o "Seed"  seed .  Outside of the endocarp is the most edible part of
this fruit, derived from the floral tube (torus) and other parts, which
corresponds to what is commonly called the core.  The shriveled remains
of the sepals, style and stamens can be seen at the end of a pome
opposite the stem, demonstrating that the ovary is   HYPERLINK
"http://en.wikipedia.org/wiki/Ovary_%28plants%29" \l "Inferior_ovary" \o
"Ovary (plants)"  inferior  in these flowers.  This type of fruit is
called a pome (See Figure 1).  In botany, a pome (after the   HYPERLINK
"http://en.wikipedia.org/wiki/French_language" \o "French language" 
French  name for an   HYPERLINK "http://en.wikipedia.org/wiki/Apple" \o
"Apple"  apple : pomme) is a type of   HYPERLINK
"http://en.wikipedia.org/wiki/Fruit" \o "Fruit"  fruit  produced by  
HYPERLINK "http://en.wikipedia.org/wiki/Flowering_plant" \o "Flowering
plant"  flowering plants  in the Subfamily   HYPERLINK
"http://en.wikipedia.org/wiki/Maloideae" \o "Maloideae"  Maloideae  of
the Family   HYPERLINK "http://en.wikipedia.org/wiki/Rosaceae" \o
"Rosaceae"  Rosaceae .  A special fruit type is given to apple and
related fruits - the pome.  The subfamily   HYPERLINK
"http://en.wikipedia.org/wiki/Maloideae" \o "Maloideae"  Maloideae 
includes apple, pear, Chinese quince, quince, loquat, medlar, mayhaw,
and tejocote.  The bulk of the fleshy edible portion derives from the
hypanthium or floral cup, not the ovary as most fruits and is called an
accessory fruit since it derives from other floral parts.  Seeds are
relatively small and black, and mildly poisonous. 

	The best know example of a pome fruit is the apple.  Other examples of
plants that produce fruit classified as a pome are pear, loquat,
azarole, mayhaw, quince, cotoneaster, hawthorn, Pyracantha, rowan, and
whitebeam.

Figure 1. Cross Section of a Pome Fruit (Apple is a Classic Example of a
Pome Fruit).

  

The current Crop Group 10, Pome fruit group, has been successful in
establishing tolerances for the seven members of this group.  There are
three pome fruit “orphan crops” grown commercially or in small
scales, and sold and consumed in the U.S. or other regions or countries.
 Many of these crops are of economic importance or have a great
potential to be grown in larger scale in the future due to their
nutritional value, or the increased market demand driven by both the
growing ethnic populations and greater awareness of these crops by the
non-ethnic population as a whole.  Being excluded from the crop groups,
tolerances requested for these commodities would have to be established
based on separate residue studies.  Without a doubt the inclusion of
these commodities in crop groups will benefit growers, consumers, save
time and tax payer’s money on residue studies, save government
agencies time in review residue data.  

ORIGIN, HISTORY OF CULTIVATION

	The center of diversity of the genus Malus is the eastern Turkey,
southwestern Russia region of Asia Minor (Republic of Kazakhstan). 
Apples were probably improved through selection over a period of
thousands of years by early farmers.  Alexander the Great is credited
with finding dwarfed apples in Asia Minor in 300 BC; and he brought back
to Greece may well have been the progenitors of dwarfing rootstocks. 
Apples were brought to North America with colonists in the 1600's, and
the first apple orchard on this continent was said to be near Boston in
1625.  From New England origins, apples moved west with pioneers, John
Chapman (alias Johnny Appleseed) and various missionaries during the
1700's and 1800's.  In the 1900s, irrigation projects in Washington
State began and allowed the development of the pome fruit industry of
which the apple is the leading species.  Apples are grown between
latitudes 30° and 50° north and south.  Limiting factor in apple
production at latitudes lower than 30° is a lack of adequate chilling
in the winter.  There are over 10,000 apple cultivars worldwide but only
a few dozen have international importance (Table 17).  The development
of more heat tolerant apple cultivars and long growing season varieties
like ‘Granny Smith’ and ‘Fuji” and the use of irrigation has
extended apple production to areas with a warmer climate.  Apples can
grow on a wide range of soil types.  The optimum soil pH ranges from 6.5
– 7.0.  The ten commodities in the proposed crop group are all cool
season temperate perennial trees gown for their fruits.  

	Pears are placed in the Rose family (Rosaceae), subfamily Pomoideae
along with apple and quince.  The genus Pyrus is composed of about 22
species, found in Asia, Europe, and northern Africa.  Two major species
are commercially cultivated:  European pear: Pyrus communis L.  This
species does not occur in nature, and possibly derives from P. caucasia
and P. nivalis (snow pear).  This is the major pear of commerce.  The
other pear is the Asian pear P. pyrifolia (Burm. f.) Nak. [syn. P.
serotina L.] and it is also called "Japanese" or "Oriental" pear, or
"Nashi".  Grown mostly in the Orient, this fruit has been increasing in
popularity in the USA over the last 20 years.

Like its relative the apple, the European pear is not found in the wild.
 Its probable ancestors are native to Eastern Europe and Asia Minor near
the Mediterranean, but it is not known when they may have hybridized to
yield P. communis.  The European pear has been selected and improved
since prehistoric times, and has been cultivated in Europe since 1000
BC.  Pears probably came to the U.S. with the first settlers on the east
coast in the 1700’s, and spread westward with pioneers.  When moved to
the Pacific Northwest in the 1800s, European pears were able to escape
fire blight, a serious bacterial disease that limited pear cultivation
in the east.  Today, over 90 % of the pear crop is grown in the Pacific
Northwest, such as the Hood River Valley of Oregon and California. 
There are relatively few cultivars of European or Asian pear grown
worldwide.  Only about 20 - 25 European and 10 - 20 Asian cultivars
represent virtually all the pears of commerce.  Almost all European
cultivars were chance seedlings or selections originating in Western
Europe, mostly France.  'Bartlett' is the most common pear cultivar in
the world, and represents about 75% of US pear production.

Asian pears were domesticated in China about the same time European
pears were in Europe, 3000 years ago.  Pyrus pyrifolia is native to
central and southern China, and probably the first to be domesticated
since fruit of wild trees is edible.  Fruit of the wild P. ussuriensis
is astringent, small, and course-textured, so that it was probably
hybridized with P. pyrifolia prior to domestication.  Chinese writings
dating from 200 - 1000 BC describe pear propagation and culture.  All of
the Asian cultivars originated in Japan and China.  Asian pears moved
from China to Japan, Korea, and Taiwan, where they are still cultivated
commercially today.  Asian pears appear more like apple than European
pear, and have hard, crisp flesh like apples when ripe, unlike the soft
flesh of the European pears.  Also, Asian pears will ripen on trees like
apples, but European pears are subject to core breakdown if allowed to
ripen fully on-tree. 

	The common European pears have a pyriform shape while Asian pears have
a round fruit shape.  As in apple, the fleshy edible portion is derived
from hypanthium tissue.  There are five central seed cavities, usually
bearing two seeds each as in apple.  The flesh contains grit cells
(termed brachysclereids), which are thick-walled, lignified cells that
give the characteristic European pear flesh texture.  Pears are thinned
to 1 - 2 fruit per spur branch and spaced 6 inches apart.  

The members of this crop group have similar uses, and all are consumed
fresh or consumed cooked or raw in various recipes including salads,
jellies, and juices.  They can also be used fresh or in a dehydrated
form.  Some of these pome fruits also have medicinal properties.  The
fact that these pome fruits are in the same family with similar
biological and cultural aspects suggests they should also encounter
similar pest problems and hence have similar needs for pest control
products in similar use patterns. 

Among the 10 commodities proposed only three are new to this crop group
(Chinese quince, Japanese quince, medlar, and tejocote.  Azarole and
Japanese quince were also found to have similar characteristics to
become a member of the Pome fruit group.  Apples and pears are the
widely grown pome fruits in the world with largest acreages and are the

GROWTH AND DEVELOPMENT OF THE POME FRUIT CROPS

	Understanding how the pome fruit crops grow and develop is a key part
of developing a pest control strategy for optimum fruit yield and
quality and a helpful reference for analysis of residue field trials by
EPA scientists.  Proper timing of pesticide applications, based on crop
growth stage and pest growth cycle can improve a product’s efficacy
and prevent crop injury and yield losses.  Pesticide labels often use
crop growth stages and codes to identify when to apply a pesticide, as
well as the pome fruit State Extension pest control recommendations and
spray schedules are based on these distinct growth stages.  For example,
the growth stages in Tables 2, 3, and 4 do not show when 

spray treatments must be applied but will show when any combination of a
pest control treatment when needed can be applied.  Rarely, if ever,
will a grower need to apply treatments at all of the key growth stages
shown for a given fruit.  The number, distribution, and content of
needed treatments will vary between the major fruit growing regions of
the world and within any given region and are dependent on pest
pressures which reduce the yield, quality, and marketability of the
fruit.  In our reviews we often have to consider the number of days from
a specific apple growth stage to harvest in order to determine the total
number of pesticide applications and to establish a preharvest interval
(PHI).  Pesticide spray application are timed according to specific
growth stages, with early season pesticide applications  are timed
according to the opening of the leaf and flower buds in the spring (see
Table 5, dormant through bloom stages), and later season applications
are called full tree cover sprays.

	Some of the internationally recognized growth stages for the pome
fruits are listed as BBCH Codes (Biologische Bundesanstalt,
Bundessortenamt and Chemical industry) and are shown in Table 1.  They
are based on the principal growth stage such as leaf development and
flowering and list a standard BBCH Code for each stage as well as a
description of each code.  Pome fruit growth stages for apple (Table 2)
and pear (Table 3) are also essential for identifying the propose
timings to scout pest problems for control of these pests and for
applications of pesticides as part of an integrated pest management
program (IPM).  A comparison of the growth stages for apple and pear
such as petal fall stage during growth and flowering will help the
reviewer understand similar growth stages for evaluating spray schedules
and label direstions (Table 4).  Fruit set is a growth stage reached in
apple, for example, 5 to 10 days after the end of bloom or when one can
readily see which blossoms have at least temporarily set fruit and which
ones have not set fruit.  In a "normal" year fungicides may be needed to
be applied at the growth stages (Table 2) green tip, half inch green,
tight cluster, pink, petal fall, and fruit set stages.  After the petal
fall stage in apple and pear (Tables 2 and 3), the pesticide
applications are often called “cover sprays” and up to seven cover
sprays may be needed.  There are also separate spray schedules for
apples intended for processing and for nonbearing fruit trees.  Examples
of growth stage use in apples is for controlling of apple scab
infections is a dominant concern of New York pome fruit growers.  The
most effective time to use oil spray to control the European red mite
and for powdery mildew is at the tight cluster stage.  In areas where
the plum curculio is troublesome, the treatment applied at the fruit set
stage has been called "the curculio spray" and treatments applied at the
petal fall and fruit set stages are important in a program to control
this pest.  Similarly for pears pesticide treatments are used primarily
for the control of pear psylla and fire blight.  One or two oil sprays
applied in the bud swell stage provides good initial control of the
psylla and blister mite (Table 3).  Fire blight may be contained by good
control of its vectors which are psylla, plant bugs, and aphids in the
green cluster and petal fall sprays and by use of a bactericide in full
bloom stage.

Apples may have pesticide applications or various cultural practices
conducted at several growth stages depending upon pest or physiological
problem (s) to be controlled.  Using integrated pest management
practices, pest populations are carefully monitored before a pesticide
application is recommended.  Again not all of the growth stages of
apples will receive a pesticide treatment, but are listed for guidance
when the pesticide label lists them as a spray application for the
specific growth stage or timing (Table 5).

CLIMATE AND SOILS AFFECT POME FRUIT ADAPTATION TO CERTAIN REGIONS:

Apples are adaptable to various climates, but can be considered best
adapted to the cool temperate zone from about 25 - 52° latitude.  They
have a more northern range than many other tree fruits due to relatively
late blooming and extreme cold hardiness.  Apples reach maturity about
120 - 150 days after bloom, with some cultivars maturing in as short as
70 days, and others as long as 180 days.  Apples are grown on a wide
variety of soils worldwide, but they prefer well-drained, loamy soils
with pH 6 - 7.  A minimum rooting depth of 4 - 5 feet is desirable. 
Trees on shallow soils will be more affected by drought and by root
injury during extended severe cold spells.  Apple trees will not
tolerate waterlogged soils for extended periods during the growing
season.  Loquat also prefers a  deep, well-drained, loamy soil with a pH
6 – 7, and they tolerate temperatures down to -11°C (12°F), but
flower buds will be killed at -2 to -7°C (18 - 28°F).  Because
flowering occurs in late autumn, frost kills the open flowers nearly
every year when grown outside the tropics, so fruiting is rare outside
of Florida, coastal Georgia, and California in the US.  Pears tolerate
heavy, poorly drained soils better than most tree fruits.  Productivity
is best on deep, well-drained loams with pH 6 - 7.  Pears have very
similar climatic requirements to apples, but are much more susceptible
to fire blight so they cannot tolerate humid, wet springs.  Asian pears
have lower chill requirements than pears and can be grown as far south
as northern Florida.  Pears have similar or slightly lower cold
hardiness than apples, tolerating 10 to -20 F.  Pears bloom one to three
weeks before apple, and are therefore prone to frost damage in most
regions.  Pears can mature in as little as 90 days, or as long as 200
days.  'Bartlett' pear is referred to as "summer pears" since they ripen
in July - August in California (115 - 140 days).  ‘Winter pears’ are
those harvested in autumn and marketed throughout the winter months,
such as 'Anjou', 'Bosc', 'Comice', 'Hardy', 'Winter Nelis', and
'Packham's Triumph'. 

U.S./NAFTA AND WORLD PRODUCTION AND GEOGRAPHICAL DISTRIBUTION OF THE
POME FRUIT COMMODITIES: 

	Proposed members of the Pome fruit crop group find widespread
distribution throughout the world.  Pome fruits are one of the largest
fruit crops produced in the world, next to grape, banana, and citrus. 
Table 6 provides a list of the hectares and production in metric tons
from various countries that are members of the International Crop
Grouping Consulting Committee (ICGCC) as countries that grow apples,
pears, and quince.  While the world total acreage for apples, pears, and
quinces have decreased from  7,817,276 ha in 1995 to 6,681,092 ha in
2007, however the total production of these fruits has increased from
63,428,802 metric tons in 1995 to 84,719,870 metric tons in 2007 (FAO
2005; Table 6).  Some “minor” pome fruits commodities have also
become more popular.  This is an indication of improved productivity. 
Worldwide, the apple is by far the most harvested pome fruit at 74 % of
the hectares followed by pear at 25 %, and by quince at < 1.0 %.  The
average yields in Mt/ha for the major pome fruits is 12.1 for apple,
11.2 for pear, and 7.1 for quince.  Asia is the predominant pome fruit
producing regions accounting for 62 % of the apples hectares and 56 % of
the production (Mt), 79% of the pear hectares and 69 % of the
production, and 57 % of the quince hectares and 60 % of the production. 
The United States has 6.7 % of their total world hectares for apples and
accounts for 6.7 % of the total production (Mt), while it accounts for
1.5 % of the total world hectares and 3.8 % of the total world
production (Mt).

	In the U.S pome fruits are widely consumed with the per capita
consumption in 2006 for the following pome fruits reported as apple at
51.2 lb with 35 % from fresh and 52 % from juice, and 8 % from canned
apples (Table 7).  Consumption of apples since 1970 has increased from
31.2 lb to 51.2 lb per capita due to increased apple juice consumption
from 6.4 lb to 26.8 lb/capita.  Pears in 2007 accounted for 5.4 lb/year
consumption in the diet with fresh pears counting for 57 % and canned
pears accounting for 43 % (Table 8).  Since 1970 pear consumption has
only increased by 0.4 lb/capita, but fresh pears has increased rapidly
(1.9 to 3.1 lb/capita) with a decline in canned pear consumption (3.3 to
2.3 lb/capita).

IMPORTS/EXPORTS OF THE POME FRUITS:

	Despite the U.S. being a major producer of pome fruits (Table 5)
significant amounts of some of the pome fruits are imported.  The amount
of a commodity can vary widely from year to year based on differences in
U.S. production, weather effects, and consumer demand.  Apples are the
most widely imported pome fruit shipped into the U.S. (Table 10).  In
1980 the import share of apple and pear consumption was 4.0 and 3.4 %,
while in 2001 it greatly increased to 7.0 % and 20.6 %, respectively. 
Also in 1980, apple juice consumption due to imports was 19.3 % while in
2001 it increased to 63.4 %.  In 2006, 7.1 % of the apple crop consumed
was from imports, apple juice 80.2 %, and 23.1 % from fresh pears.  In
2007 over 206,563 MT of fresh apples were imported to the U.S. (USDA
Foreign Agriculture Trade Statistics, FATUS).  Compared to 1975
consumption of fresh apples (2.8 %) and pears (2.6 %) and apple juice
(15.3 %) due to imports has greatly increased.  Approximately 60 % of
the apples were imported from Chile, 23 % from New Zealand, and 15 %
from Canada.  Frozen apple juice concentrate in 2007 was 169,348
Kiloliter with 43 % Brazil, 37 % from Peoples Republic of China, and 11
% from Turkey, and 5 % from Argentina.  Apple juice not frozen in 2007
was 2,113,643 kiloliters with 54 % from Peoples Republic of China 19 %
from Argentina, and 17.0% from Chile.  There were 7,118 MT dried apples
imported from Chile (43 %), Peoples Republic of China (39 %), and
Argentina (16 %).  Imported fresh pears in 2006 totaled over 106,887 MT
with 49 % from Argentina, 28 % from Chile, 10 % from Republic of Korea,
and 8.7 % from Peoples Republic of China.  Pear juice has been imported
at over 190, 991 KL from Argentina at 56 %, Peoples Republic of China at
38 % and Chile at 4 %.  According to the USDA, ERS in 2006 approximately
270,669,000 lb of fresh market apples were imported, and 171,704,000 lb
of fresh market pears and quinces were imported.  Approximately
425,085,000 single strength apple juices were imported to the U.S.

U.S. POME FRUIT PRODUCTION AND GEOGRAPHICAL PRODUCTION:

	Production in the U.S. is based on the USDA 2006 Agricultural
Statistics, FAO Statistics, 2007, USDA ERS 2007 Noncitrus Fruits
Summary, USDA NASS Crop Production, 2007, and the U.S. Agricultural
Census, 2002:  According to the 2002 AGCensus pome fruits (apples and
pears) were grown on over 544,826 A.  The planted acreages for the pome
fruits in the United States are listed in Table 12.  Apples are grown
commercially in 35 states.  Over 37 % of the apple acres are in
Washington followed by New York and Michigan at 11 % each (Table 13). 
Washington State produces over 71 % of the total U.S. fresh market apple
production followed by New York at 11 %, Michigan at 4.4 %, California
at 2.5 %, and Pennsylvania at 2 %.  Apple yield/acre averages 12.6 T/A,
while the average yield/A for pears is14.7 T/A (Table 12).  The top pear
producing states is Washington with 40.3 % of the total U.S. acres,
while California and Oregon each have over 26 % of the pear acres (Table
14).  Pear yields will depend on the state where they are grown and
range from 5 to 16.8 T/A.

Specific Pome Fruit Crop Production:

Apple:

	Apples are the most important tree fruit produced in the temperate
zone.  Apples are also grown in EPA Crop Production Regions 1, 2, 5, 9,
10, and 11.  Other commercial production regions include significant
imports from Canada, New Zealand, Chile, South Africa, China, and
Brazil.  In 2002 China had produced 20.9 million tons on 2,365,000 ha
while the U.S. produced 4.7 million t on 185,000 ha.  However, yield in
t/ha varied from 8.9 t/ha in China to 25.2 t/ha in the USA.   There are
over 2000 apple cultivars, with eleven cultivars accounting for over 90
% of the apples sold in the US and worldwide about 40 cultivars supply
the commercial world production (Table 17).  Of it’s over 2.3 million
hectares, China has over 45 % of its apple production limited to only
the ‘Fuji’ cultivar.  Despite the wide availability of newer apple
cultivars, ‘Red Delicious’ is still the most widely grown cultivar
in the world.

Azarole:

	Azarole ranges from Europe to western Asia, and is a deciduous tree
growing to 10 m and has been long grown in Europe.  It is hardy to zone
6 and is not frost tender.  It is in flower in June.  The scented
flowers are hermaphrodite (have both male and female organs) and are
pollinated by midges.  The plant prefers sandy, loamy and can grow in
heavy clay soil.  The plant prefers acid, neutral or basic soils and can
grow in very alkaline soil.  It can grow in semi-shade or no shade. 
Azarole requires moist or wet soil and can tolerate drought.  The plant
can tolerate strong winds but not maritime exposure, and it can also
tolerate atmospheric pollution.  In South Australia it is listed as a
noxious weed.  In Asia the fruits are eaten fresh and mixed with sugar
to make a sweet wine, jam, or jelly.  This plant can also be used as an
ornamental for its brightly colored flowers and for wildlife cover.  

Crabapple:

	Crabapples are native species of apple-like fruits that are grown
mostly for pollinators in apple orchards or as an ornamental specimen. 
There are varieties such as ‘Hyslop’ and ‘Red Siberian’ that
produce relatively large fruit that can be used as a food crop and are
processed for cinnamon apple rings.  These are hybrids of native species
with apples and in general, the trees are hardier than most apple
varieties. These are round yellow fruits 1 to 2 inches in diameter that
have a red to maroon blush.  Pollinator and ornamental varieties are
grown everywhere apples are grown.  Crabapples are grown in California,
New York, and Washington, and other commercial production regions
include British Columbia, Canada.

Loquat: 

The loquat is a cold-tender evergreen tree native to Southeast Asia that
grows in subtropical areas or tropical highlands.  It has been grown in
Japan for >1000 yr, where over 17,000 tons are produced annually. 
Brazil also has some production near Sao Paulo.  More commonly, it is
grown as an ornamental tree in the southeastern US and California,
Mediterranean countries, and some parts of central and South America. 
Domestic cultivars include ‘Champagne’, ‘Thales’, ‘Advance’,
‘Fletcher’ and ‘Miller’.  It is produced in the U.S. in
California, Hawaii, and Florida and other commercial production regions
include Japan, India, Spain, Pakistan, Turkey, and Israel.  Japan grew
1,890 hectares producing 6,730 tons in 2005 (NAGASAWA 2006c).  In 2000,
the major producing loquat country was China with over 40,000 ha and
200,000 Mt of produce.

Mayhaw:

	Mayhaws are native to the United States and are shrubs or round-topped
small tree to 30 feet tall.  Mayhaws flower early to late February to
mid-March in southern Georgia and the fruit ripens mostly in early May
but some ripen through June.  The fruit is a small pome, yellow to red,
acid and juicy, resembling cranberries in appearance.  In the U.S. it is
grown in North Carolina south to northern Florida and west to east Texas
and throughout California.  Mayhaws are native to the swamps and
lowlands of the Gulf Coast states in the U.S.  They have been collected
from wild trees in the Deep South since antebellum times, and are rarely
cultivated in orchards today.  Over 75 varieties have been developed
since 1986.  In China there were 240 million trees and 4,500 million
pounds of fruit annually in 1996.  Mayhaws are native to north temperate
zone.11 and to temperate zones of China.  EPA production Regions are 2,
3, 4, and 6.

Medlar:

	The Medlar is native to the eastern part of the Mediterranean and the
eastern part of Turkey.  This plant is small, flat topped, deciduous
tree that grows to 20 feet high.  It is a close relative of hawthorn
which lacks thorns. In late spring, large white or slightly pink
blossoms are borne singly on ends of short shoots and almost every
flower sets fruit.  The fruit is 1 to 2½ inches in diameter and
resembles a small russet apple, tinged dull yellow or brown color with
the calyx end flared open.  The flesh is as soft as a baked apple. 
Embedded in the pulp are five large stone like seeds.  Fruit are best
picked at early leaf drop prior to heavy frost.  At harvest, the fruit
are rock hard and must soften prior to consumption.  Ripening takes two
weeks to one month after harvest. . The wood of the medlar is used for
spears and walking canes.  Cultivation is still common in France and
Germany.

Pear:

	Pears are a temperate zone fruit and grown on a wide variety of soils. 
They are similar to apples in many respects.  The tree is of medium
size, up to 30 to 40 feet in height, but usually held to under 20 feet
by pruning.  They differ from apples in having "grit" cells in the flesh
of the fruit. In general, pears are pyriform in shape, tapering toward
the stem, although some varieties are nearly round.  Fruit size varies
in varieties from less than 2 inches in diameter up to 3 inches.  Fruit
surface in some varieties is russet but in others is free of russet and
covered with a thin layer of wax.  Trees tend to be more upright than
apples. Pears can be classified by maturity date; summer, autumn and
winter.  They are the only temperate tree fruit that cannot be left on
the tree to ripen.  Major production in U.S. is of the common or
European pear.  Major commercial varieties/types of this pear include:
‘Anjou’, ‘Bartlett’, ‘Bosc’, ‘Comice’, and ‘Seckel’.
 Days after full bloom to harvest for the varieties range from 110 –
150 days.  There are significant imports from Chile and Argentina. 
Other growing regions of pears include Australia, Canada, Japan, New
Zealand, South Korea, South Africa and Europe.  EPA Crop Production
Regions for pears includes Regions 1, 10, and 11.

Pear, Oriental (Asian):

Most cultivars of the Oriental pear, now called Asian pears do resemble
apples in that they have fruit that are round and have a crunchy
texture.  The Japanese cultivars tend to be more circular in shape,
while the Chinese cultivars are more oval or pyriform (pear-shaped). 
All Asian pear cultivars should be considered self-incompatible.  Mature
trees can reach heights of more than 20 feet.  Asian pears comprise a
large group of pears that are crisp in texture and, when mature, are
good to eat as soon as harvested or for several months after picking if
held in cold storage.  This ready-to-eat feature may make them more
acceptable to some people than European pears that are usually served
when soft and juicy, which condition takes about a week to occur after
removal from cold storage.  There are three types of Asian pears based
on shape and color.  These are: (1) round or flat fruit with yellow to
green fruit; (2) round or flat fruit having a bronze colored skin with
rusetting, and (3) pear shaped fruit with either smooth or russeted
skin.  Asian pears have been grown commercially in Asia for centuries
and are very popular in Japan, China, and Korea.  Most new Asian pear
plantings in California are in Fresno, Tulare and Kern Counties.  A few
plantings exist in Yakima and Wenatchee, Washington, and others are
found in Hood River and Willamette Valley in Oregon. In the last few
years plantings of Asian pears were made in New Zealand, Australia,
Chile, France, and the eastern and southeastern United States.  It is
roughly estimated that 4,000 - 5,000 acres of Asian pears are planted in
California, Oregon and Washington.  Since 1984 about 100,000 trees (500
acres) of Asian pears have been planted every year in California.  Most
popular Oriental pears are 20th Century ‘Nijisseiki’, ‘Kosui’,
‘Kikusui’, ‘Hosui’, ‘Shinseiki’, ‘Shinsui’,
‘Shinko’, and ‘Niitaki’.  There are a few cultivars of hybrid
origin.  Other commercial production regions: Japan grew 15,200 hectares
producing 361,400 tons in 2005 (NAGASAWA 2006c), and some fruit is
exported to the United States in October and November.  China and Korea
are also growing these pears for domestic consumption and export to the
US and Canada.

Quince:

	Quinces are fruits closely related to apples and pears, but are of
lesser economic importance.  It is thought that it is native to northern
Iran and Turkestan.  The plants are deciduous thornless shrubs or small
trees.  Generally they are not over 20 feet high.  Fruits are mostly 2
inches up in diameter, covered with pubescence.  Fruit color is
generally yellow.  Fruit flesh is rather hard with a bitter acid taste. 
The most common cultivars/varieties include “Champion”,
“Pineapple”, “Smyrna” and Van Deman”.  The quince has been
cultivated for over two thousand years for its edible fruit and its
seed. It is also much used as a dwarfing rootstock for pears and some
other fruits.  California is key production area with 100 - 200 acres. 
No available statistical information from other areas.  Other commercial
production regions: Mediterranean, Argentina, and the Middle East. 
Argentina produces over 20,000 t/ha.  The largest are of quinces is in
the Mediterranean area (35.2%) and China (22.3%).  

Quince, Chinese and Quince, Japanese:

The Chinese quince is native to China and Indo-China, and cultivated in
Japan.  Chinese quince was introduced to Europe in 1796 and Japanese
quince in 1869.  The crop is cultivated in the north and Eastern Europe
including Baltic areas and Latvia.   It is hardy to zone 5 and is not
frost tender.  It is in flower from February to June, and the seeds
ripen in October.  The flowers are hermaphrodite (has both male and
female organs) and are pollinated by bees.  It is noted for attracting
wildlife.  The fruit can be apple or pear-shaped and up to 6.5 cm long x
6.5 cm wide.  It is a very ornamental plant and a good bee plant,
flowering early in the year and providing pollen and nectar.  The
Japanese quince is a closely related species and also occurs in central
and south Japan, and it has been planted in Latvia in the 1970’s and
in 1996 approximately 300 ha had an average yield of 12 – 15 T/ha.  It
can grow 0.6 – 1.2 m tall and 5 m wide.  Commercial production of the
Japanese quince is in Belarus, Finland, Germany, and Poland.  Other
production regions include Japan grew 55 hectares producing 335 tons in
2003.  Both of these quinces are also grown for ornamental purposes.  

Tejocote:

	Tejocote is native to America and it is hardy to hardiness zone 7 and
is not frost tender.  The flowers are hermaphrodite (has both male and
female organs) and are pollinated by insect midges.  The plant prefers
sandy, loamy and heavy (clay) soils and can grow in heavy clay soil. 
The plant prefers acid, neutral and basic (alkaline) soils.  It can grow
in semi-shade or light woodland or no shade.  It requires moist or wet
soil and can tolerate drought.  The plant can tolerate strong winds but
not maritime exposure.  It can tolerate atmospheric pollution. 

COMPARISON OF POME FRUIT CULTURAL PRACTICES:

General Planting Design, Training, and Pruning (adapted from Rieger,
2006, Robinson, 2003, and USDA Crop Profiles, 2003): 

	Pome fruit orchard planting systems are designed to improve the
production efficiency by managing variables of rootstock, tree spacing,
arrangement, canopy shape, pruning, tree training methods and support
systems.  

	The more modern planting systems are based on higher tree densities
than 50 years ago when the tree density ranged from 70 - 100 tree/ha to
today range from 1000 – 6000 trees/ha.  The increase in density is due
to development of dwarfing rootstocks.  In the nursery, apple scions and
rootstock are grafted together.  A scion is the detached shoot or twig
containing buds from a desired tree, used in grafting.  Rootstock is
selected for tolerance to pressures such as pests or cold, in addition
to how well it influences the final tree’s vigor, size, and fruit
quality.  Yields may be realized in the third year after planting
compared to 5 - 6 in an older orchard planting density.  However, many
highly productive commercial orchards today have 150 - 180 trees per
acre and higher density could be anything over 180 trees per acre. For
the purposes of this publication, there are several characteristics in
addition to tree number that are included in a high density orchard
system. Besides having an increased number of trees per acre, a high
density orchard must come into bearing within 2 - 3 years after
planting.  Each type of planting system has different pruning and
planning plans.  

Consistent early fruit production is essential to offset the increased
establishment costs.  It is also very costly to hold trees on more
vigorous rootstocks in an allotted space required for a high density
orchard.  To maximize the production of a high density orchard, it is
also necessary to modify the training system and training and pruning
techniques from traditional methods.  Since trees will be bearing fruit
early, a permanent tree support system is also required.  It is
essential to crop trees very early in the life of the orchard to offset
the costs of establishment and to aid in managing vegetative growth.
Early production is directly related to number, the greater the light
interception by that acre of land early in the life of the orchard.  To
the extreme, there are orchards planted in Europe and the Pacific
Northwest with 5,000 - 9,000 trees per acre. Although, these orchards
may be very productive early in their life, it is doubtful that they
would be profitable, or manageable, under economic conditions in the
Southeast.  Research conducted at Cornell University’s Geneva Research
Station in New York found that for the first seven years of an orchard,
the yield increased with tree density, independent of the
size-controlled rootstock used.  The most dwarfing rootstocks produced
significantly larger yields in the third year.  As tree density
increased, profit ability increased up to approximately 1,000 trees per
acre.  Preliminary studies in North Carolina indicate that tree
densities of 450 - 600 trees per acre are most profitable for the
Southeast given the climate, soils, and markets.

	Orchard planting systems are categorized from tree canopy shapes.  Four
basic canopy shapes are: spherical, conic, flat-fan, and Y - or V -
canopy shapes.  The spherical shaped canopy system was most common in
early 1900’s and contained a large tree with a height of 6 - 8 m and a
main trunk diameter of 1.8 – 2.0 m.  These large globe canopies took
10 – 15 years to produce high yields.  Primary advantage of the
spherical shapes is that they are the natural shape of an apple tree. 
This system was replaced in the mid 1900’s and in the early 1960’s
the conic system developed as an improved tree form to allow more light
penetration through the canopy.  The mini-central leader system was
developed at Cornell University to have semi-dwarf trees supported with
a 2.5 m tree spike supporting the trees and ranging from 500 – 1000
trees/ha.  The spindle bush system was also developing in the early
1960’s designed to improve yields and it became the dominant planting
system in Europe.  The trees are fully dwarf, narrow, cone shaped trees
to allow for high density plantings ranging from 1500 – 4000 trees/ha.
 The narrow slender shape of the canopy helps the leaves to be well
exposed to sunlight.  The conic shaped system are currently the dominant
tree form in most of the world’s apple growing regions and allows the
tree to grow in a fairly natural shape with minimal labor allowing good
light penetration throughout the canopy, but the upper branches of the
tree as they mature may begin to shade out the lower limbs.  The slender
spindle is most common in Northern Europe and the vertical axis system
is most common in the rest of the world.  The flat fan canopy systems
utilize trellis to improve labor efficacy.  This tree system trains a
tree to a 3 m tall using a 4 – 6 wire vertical trellis which also
serves to support the tree.  Tree height is maintained at 4 – 5 m and
densities of 100 - 2000 trees/ha.  Common tree spacings are 1.5 – 2.5
m in the row and 3 – 4 m between rows.  The advantage of the flat fan
systems is the ease of tree training and to help mechanize orchard
picking operations as well as allow good light penetration within the
canopy.  The disadvantages of flat systems are the labor costs to
maintain the canopy and low tree planting densities.  The V shaped apple
canopies became popular with the development of the Tatura trellis in
1970’s to utilize dwarfing rootstocks.  They are categorized by tree
shape and branch training protocols using either a V- shape of Y- shape
tree.  The Y- shaped trees have a vertical trunk with the arms or limbs
trained to either side of the trellis.  The V- shaped trees have the
whole tree leaned to one side of the trellis while the next tree in the
row leans to the opposite side of the V - trellis.  The Tatura trellis
keep the trees headed at 50 cm height with 6 wires per side and close in
row spacings of 1 m with 5 m between rows.  The Geneva trellis system is
aY - shaped system trained in a more fan type position with a 2 m tall
trellis and three wires per side with 1.5 – 1.8 m in row spacings and
4 m between rows.  The V - shaped systems have become very popular over
the last 25 years because they have high yields at maturity and allow
good light penetration.  With a vertical trunk and is conducive to use
of mechanical equipment between rows.  Also less fruit sun scald occurs
in this type of trellis system.  The disadvantage of the V systems is
the initial cost of establishment and tree training, and while fruit
size may be smaller than with other training systems, the yields may be
higher with this system.  

Efficient use of labor to harvest and prune from the ground or from a
short stool is another advantage of using a high density system.  It is
difficult to find workers who are willing to climb ladders to work in
traditional orchards in today’s market, not to mention the liability
that must be assumed for their employees.  Another advantage is the
potential to have higher quality fruit for a longer period of time by
maintaining light interception in the smaller trees of higher density
orchards. Pesticide application efficiency may be much higher in higher
density orchards as well.  Although there are many advantages to high
density orchards, the disadvantages must also be considered.  The
primary disadvantage is the high cost of planting orchard establishment.
 High density orchards are also unforgiving in terms of lack of
management systems require more training and minimal pruning during the
first 6 years than traditional systems, especially during the summer. 
Another potential disadvantage involves re-educating orchard managers
and workers in the training and pruning techniques required for higher
density orchards. 

The ideal site for a pome fruit orchard is an area of rolling land. 
Plant pome fruits on slopes that are not too steep to be safely
traversed with equipment.  The tops of hills are not necessarily good
sites as orchards located there are more vulnerable to freezes than the
sides of hills.  Also, soils on the tops of hills are frequently shallow
due to erosion. 

Specific Individual Pome Fruit Cultural Practices:

Apple:

Small to medium sized tree with spreading canopy, to 30 ft in wild,
generally are maintained to 6 - 15 ft in cultivation.  Tree size and
shape is heavily dependent on rootstock and training system.  Leaves are
elliptical with serrate margins, dark green with light pubescence on
underside.  Petals are white when open, but have red-pink undersides
when opening, hence the "pink" bloom stage. The ovary is inferior,
embedded in the floral cup or hypanthium, containing 5 locules, usually
2 ovules per locule.  The inflorescence is a cyme of 4 - 6 flowers, with
the center flower opening first; the central flower is often called the
"King bloom", and has the potential to produce a larger fruit than other
flowers.  Flowers are produced terminally from mixed buds (containing
both leaves and flowers) on spurs, or to a lesser extent on long shoots.
 Spurs form on two year old and older wood, and generally grow only a
fraction of an inch each year.  Fruiting begins 3 - 5 years after
budding, although a few fruit may be produced in the second year. This
varies with rootstock (dwarfing) and cultural practices (excessive
pruning = delay). Fruit are usually thinned to 1 per spur, with spurs
spaced 4 - 6 inches apart for attainment of marketable size. Apples are
generally thinned with chemicals such as the insecticide carbaryl or the
synthetic auxins such as naphthalene acetic acid (NAA).

	The apple tree is of medium size, up to 30 to 40 feet in height, but
usually held to under 20 feet or less by pruning.  They are propagated
by budding or grafting onto rootstocks.  Leaves are entire and up to 4
inches long, pubescent when young, near glabrous later.  The fruits are
oblate to slightly conic in shape, with depressions at the stem and
calyx ends, 2 1/4 up to 3 1/2 inches in diameter.  They consist of a
thin outer peel, a thickened edible flesh and a central core of 5
carpels, in which the small seeds are borne.  The peel is pubescent when
young, later becoming smooth and waxy.  Formerly some russeted varieties
were grown.  These have disappeared in commercial orchards, but russeted
areas may occur on some varieties due to weather or other injury. 
Important commercial varieties/types include: ‘Braeburn’,
‘Crispin’, ‘Mutsu’, ‘Empire’, ‘Fuji’, ‘Gala’,
‘Golden Delicious’, ‘Granny Smith’, ‘Ida Red’,
‘Jonagold’, ‘Jonathan’, ‘McIntosh’, ‘Red Delicious’, and
‘Rome’.  Throughout its history of cultivation, at least 10,000
apple cultivars were developed, many of which are now lost.  Apples are
adaptable to various climates, but can be considered best adapted to the
cool temperate zone from about 35 - 50° latitude.  After planting
rootstocks full production may not occur until 5 – 6 years later. 
Bloom to harvest in 70 to 170 days, depending on variety and location. 
For example Red Delicious is harvested 140 – 160 days after full bloom
(Table 18).  The maturity dates for each apple cultivar will vary
depending upon the environmental conditions (temperature, rainfall, soil
types) in the Region where they are grown.  Some representative examples
and ranges of apple cultivar maturity and days after full bloom to
harvest are listed in Table 18, and to determine the number of days from
petal fall to harvest for a specific apple cultivar and you would
subtract seven days from the days after full bloom (DAFB).  Apples are
T- or chip-budded in the nursery, and sold as 1-year-old whips on 1.5 to
2-year-old rootstocks.  Rootstocks are also produced vegetatively,
generally by mound layerage.  The range of rootstocks available for
apple permits a wide variety of orchard designs and tree training
systems.  In most cases, trees are grown in rectangular arrangements or
hedgerows.  Conventional apple orchards on seedling rootstocks require
spacings of 20 x 20 (110 trees/acre) to 40 x 40 ft (27 trees/acre). 
More intensive orchards (400 trees/acre) are generally planted to form
hedgerows or solid rows of fruiting wood where individual trees lose
their identity.  Apples must be picked by hand to avoid bruising and
reduction of fresh market quality grade.  Fruit must be picked carefully
to avoid damaging the spur, where next season's fruit will be borne.

Azarole:

	Azarole is a very easily grown plant; it prefers a well-drained loamy
soil.  Once established, it succeeds in excessively moist soils and also
tolerates drought.  It grows well on a chalk soil and also in heavy clay
soils and grows up to 10m tall.  A position in full sun is best when
plants are being grown for their fruit, they also succeed in semi-shade
though fruit yields and quality will be lower in such a position.   Most
members of this genus succeed in exposed positions, they also tolerate
atmospheric pollution.  The azarole has long been cultivated for its
edible fruit in Southern Europe, though it is now not as popular. 
Seedling trees take from 5 - 8 years before they start bearing fruit,
though grafted trees will often flower heavily in their third year.  The
flowers have a smell somewhat like decaying fish.  This attracts midges
which are the main means of fertilization.  When freshly open, the
flowers have more pleasant scent with balsamic undertones.  Hawthorns in
general hybridize freely with other members of the genus.  Seedlings
should not be left in a seedbed for more than 2 years without being
transplanted.  Seed - this is best sown as soon as it is ripe in the
autumn in a cold frame, some of the seed will germinate in the spring,
though most will probably take another year.  Stored seed can be very
slow and erratic to germinate, it should be warm stratified for 3 months
at 15° C and then cold stratified for another 3 months at 4° C.  It
may still take another 18 months to germinate.  Scarifying the seed
before stratifying it might reduce this time.  Fermenting the seed for a
few days in its own pulp may also speed up the germination process. 
Another possibility is to harvest the seed 'green', as soon as the
embryo has fully developed but before the seed coat hardens and plant it
immediately in a cold frame.  If timed well, it can germinate in the
spring.  If you are only growing small quantities of plants, it is best
to pot up the seedlings as soon as they are large enough to handle and
grow them on in individual pots for their first year, planting them out
in late spring into nursery beds or their final positions.  When growing
larger quantities, it might be best to sow them directly outdoors in a
seedbed, but with protection from mice and other seed-eating creatures. 
Grow them on in the seedbed until large enough to plant out, but
undercut the roots if they are to be left undisturbed for more than two
years.  The   crop may grow from 6 – 10 m high, and the fruit will
ripen in August – September.  The small red fruit has a pleasant
aromatic flavor.  It ripens in early to mid-autumn.  There are yellow,
red, and white fruited varieties.  Fruits are harvest mechanically or
hand picked. 

Crabapple:

A crabapple is basically a small apple, and is not as important crop as
apples.  The plants are grown primarily as ornamentals and cultivars are
chosen because of their beautiful flowers, foliage, or fruit, although a
few growers produce the fruit commercially.  The fruit is preserved or
pickled or it is used in making jellies.  No production data are
available on the quantity of fruit that is used commercially.  The
general appearance is similar to a small bearing apple tree.  Culture is
also similar to the culture of apple trees.  The flower is similar to
that of the apple.  The fruit are round yellow fruits 1 to 2 inches in
diameter that have a red to maroon blush.  Crabapples are native species
of apple-like fruits that are grown mostly for pollinators in apple
orchards or as a beautiful ornamental specimen.  If commercial fruit
production is anticipated, and crabapple trees are grown along with
other fruit trees in commercial orchards, there is likelihood that
additional pollinating insects will be required.  If the grower is
providing bees for his other fruits, then he should provide enough for
crabapples also.  There are varieties such as ‘Hyslop’ and ‘Red
Siberian’ that produce relatively large fruit that can be used as a
food crop and are processed for cinnamon apple slices.  Crabapples are
considered to be apples except for being less than 2 inches in diameter,
but some crabapples are greater than 2 inches in diameter and some
dessert apples are small.  Western crabapple is native to North America.
 Shrub or small tree, to 35 feet tall, armed with sharp spur-shoots, the
older bark is deeply fissured.  Leaves are alternate, deciduous, lance-
to egg-shaped, to 10 cm long, pointed at the end, toothed, with
irregular lobes; the leaves turn red or yellow-orange in fall.  Flowers
are white to pink (mid-April/mid-May), showy, calyx of 5 lobes, petals
5, styles 3 - 4 from inferior ovary, numerous stamens.  Fruits are
pomes, initially green becoming yellow or reddish, to 15mm and
egg-shaped, tart.  Bloom to harvest in approximately 4 months.  Western
crabapple is harvested in late summer and early fall. Flower in May. 
Flowering crabapples may be planted almost any time of the year.  Balled
and bur lapped stock and containerized trees can be planted any time
after spring frosts end through fall until about three weeks before the
ground freezes.  However, bare root trees should only be planted in the
spring.  Bare root trees become too stressed if planting is delayed past
early spring.  Crabapples prefer light (sandy), medium (loamy) and heavy
(clay) soils, require well-drained soil and can grow in heavy clay soil.
 The plant prefers acid, neutral and alkaline soils.  It can grow in
semi-shade and light woodland or no shade and requires moist soil. 

Loquat

	Loquat grows in subtropical areas or tropical highlands.  Propagated by
seed or grafting.  The first crop will mature in 2 - 3 years after
grafting while trees from seedlings which will take 8 – 10 years to
mature.  They are extremely long lived up to 90 years.  Loquats can be
propagated by various grafting methods, including shield-budding or
side-veneer grafting and cleft-grafting.  The use of loquat seedling
rootstock usually results in a comparatively large tree with a high
canopy.  Cultivars grown on quince rootstock produce a dwarfed tree of
early bearing character.  The smaller tree has no effect on fruit size
and gives adequate fruit production with the advantage of easier
picking.   Loquat trees are evergreen, rounded in form, up to 30 feet
high.  Dark green leaves vary from eight inches to a foot long.  Trees
are spaced about 20 - 25 ft apart in orchards and at a density of 500
– 600 trees/ha.  Trees will stand winter temperatures down to about 12
° F.  It prefers a soil ranging from pH of 5.0 – 8.0.  Flowering time
is unusual; occurs in November - January, depending on location. 
Flowers open and set fruit in autumn, and if temperatures reach 25 ° F
or lower in winter, fruit crop will be lost.  Flowers and fruits are
produced on large panicles.  Individual fruits are pyriform or oval, l
1/2 to near 3 inches long, and covered with a tough, pubescent skin
which separates readily from the pulp when ripe.  The fruit is a white
or yellow pome, like apple and pear, generally 2 – 5 cm in diameter
with 3 to 5 seeds, and with the calyx persistent and weighs 30 – 40g
with some cultivars ranging up to 200g.  Flesh is firm and creamy, mild,
sub-acid in flavor.  Domestic cultivars include ‘Champagne’,
‘Thales’, ‘Advance’, ‘Fletcher’ and ‘Miller’.  Loquat is
propagated by seed or grafting, and the first crop will be in 2 - 3
years after grafting.  The crop timing from bloom to maturity is 120 -
200 days.  Harvest time in California is from March to June, and in
Florida it matures in March and takes 7 – 10 days to harvest the crop.
 Fruit must be picked by hand to avoid injury and classified by grade
based on quality and size.  It is eaten out of hand fresh or fruit
salads.  Also cooked for desserts, sauces or preserves, and are also
grown as an ornamental.

Mayhaw:

	Mayhaw is a long living (> 50 years) perennial shrub or round-topped
small tree to 30 feet tall and look similar to crabapple trees.  The
name "Mayhaw" is a conjugation of the month of ripening (May) and the
common name for Crataegus spp. (Hawthorn).  Mayhaws are a group of
species in the genus Crataegus, family Rosaceae.  Primary species
include C. aestivalis, C. opaca, and C. rufula.  They are closely
related to apple and pear, and have been used as exotic dwarfing
rootstocks for both.  In the U.S. over 75 varieties of mayhaws have been
developed.  Mayhaws flower early (late February to mid-March in southern
Georgia) and the fruit ripens mostly in early May but some ripen through
June.  The fruit is a small pome that is ½ to 1 inch in diameter,
yellow to red, acid and juicy with a whitish pulp, resembling crabapples
or cranberries in appearance.  Two to five pieces of hard-shelled seeds
are located in the center of the fruit.  Since mayhaws contain a high
red pigment and pectin they are a natural source of color and texture
for jelly.  The bloom to harvest is about 3 months and some can be
harvested for about 30 days.  Mayhaws are ripe in April and early May
and can be harvested by shaking the tree and catching the fruit by using
nets under the tree or by hand.  Under natural conditions seed do not
germinate until over wintered.  Mayhaw softwood stem cuttings can also
be rooted under intermittent mist or in a humidity chamber during the
summer.  Mayhaws are easily grafted during dormancy (late winter).  For
rootstocks mayhaw appears to be initially compatible with any hawthorn
species.  A few selections have been made, like the relatively
large-fruited 'Texas Superberry' or the even-ripening 'Lodi'  Bloom
occurs over an extended period of time and the fruit are reported to be
fairly frost hardy once past the bloom period.  The suggested tree
spacing for a permanent orchard is 4.6 - 6.1 m (15 - 20 ft) in the row
and 5.5 - 6.1 m (18 - 20 ft) between rows giving 270 - 400 trees/ha or
109 - 161 trees/A.  Tree height ranges from 1 – 12 m tall.  The fruit
is mainly used to make jelly.  

Medlar:

	This plant is small, flat topped, deciduous tree that grows to 20 feet
high, that is native to the eastern part of the Mediterranean and the
eastern part of Turkey.  Medlar is a close relative of the hawthorn
which lacks thorns.  In late spring, large white or slightly pink
blossoms are borne singly on ends of short shoots.  Almost every flower
sets fruit.  The fruit is 1 to 2½ inches in diameter and resembles a
small russeted apple, tinged dull yellow or brown color with the calyx
end flared open.  The flesh is as soft as a baked apple.  Embedded in
the pulp are five large stone like seeds.  Fruit are best picked at
early leaf drop prior to heavy frost.  At harvest, the fruit are rock
hard and must soften prior to consumption.  Ripening takes two weeks to
one month after harvest.  After harvest the fruits are left until they
become brown inside and half rotten and this process is called bletting
and this process takes 2 – 4 weeks after harvest.  Once bletted the
fruit will keep for several weeks and has a taste like applesauce with
some cinnamon.  Flowering occurs in late May or June and the fruit
matures in October to December.  The fruits are small in size 1 ½ inch
diameter (4 cm), and are left on trees until they are over ripe.  The
fruit weight can vary from 10 - 80 g and a yield of 30 – 35 kg/tree is
possible.  The planting site must be in a sunny position and protected
from the wind, as the trees are very brittle and susceptible to wind
damage.  Young trees are best if thinned and pruned to desired shape. 
Medlars are slow growing but bear fruit at an early age with the tree
height dependent on the rootstock.  They will reach up to 3.5 m (12 ft)
in height when grafted onto a quince rootstock or 4.5 m (15 ft) or
taller if grafted onto a pear rootstock and may be productive for more
than 30 years.  The trees are spaced in the row from 3.5 6.0 m. 

Pear:

	A medium sized, upright tree growing to 30 ft tall, generally 8 - 18 ft
in cultivation.  Tree size is heavily dependent on rootstock and
training system.  Leaves are elliptical to ovate with acute tips, with
finely serrate or entire margins, 2 - 4 in length.  Flowers are about
one inch diameter with white petals, and similar to apple except for
having longer pedicels.  The inflorescence is corymbose, containing 5 -
7 flowers also different from apple.  Pears are a temperate zone fruit
and grown on a wide variety of soils.  They are similar to apples in
many respects.  The tree is of medium size, up to 30 to 40 feet in
height, but usually held to under 20 feet by pruning.  They differ from
apples in having "grit" cells in the flesh of the fruit.  In general,
pears are pyriform in shape, tapering toward the stem, although some
varieties are nearly round.  Fruit size varies in varieties from less
than 2 inches in diameter up to 3 inches.  Fruit surface in some
varieties is russeted but in others is free of russet and covered with a
thin layer of wax.  Trees tend to be more upright than apples.  Pears
can be classified by maturity date; summer, autumn and winter.  They are
the only temperate tree fruit that cannot be left on the tree to ripen. 
Major production in U.S. is of the common or European pear.  Major
commercial varieties/types of this pear include: ‘Anjou’,
‘Bartlett’, ‘Bosc’, ‘Comice’, and ‘Seckel’.  'Bartlett'
and its sports are referred to as "summer pears" since they ripen in
July - August in California (115 - 140 days).  "Winter pears" are those
harvested in autumn and marketed throughout the winter months, such as
'Anjou', 'Bosc', 'Comice', 'Hardy', 'Winter Nelis', and 'Packham's
Triumph'.  Bloom to harvest in 90 to 200 days (Table 19).  The cultivar
‘Bartlett’ has a 110 – 133 day from bloom to harvest, ‘Bosc’
from 130 - 145, and ‘D’Anjou from 120 – 150 days.  Pears are
propagated by budding or grafting onto rootstocks.  T-budded or
chip-budded, quince rootstock are generally dwarfing, but sometimes
require double budding.  Pear orchards are designed very similar to
apple orchards.  Standard trees are spaced at 25 x 25 ft (70
trees/acre), but hedgerow forms are more common in high density
plantings, with hundreds of trees per acre.  Pollinizers are planted in
alternate rows, or every 10th or 15th tree within hedgerows.  The most
common system is central leader for free-standing trees and some form of
palmette for trellised orchards.  Initial tree training is particularly
important with pear since scaffolds tend to grow nearly vertically,
causing poor crotch angles and delayed fruiting.  Other than this
tendency to grow upright and therefore greater need for limb spreaders,
pears are trained and pruned in the same way as apples.  European pears
are harvested when "firm mature"; flesh firmness is the most reliable
indicator of pear maturity.  Firmness in the range of 10 - 15 lbs as
measured by a pressure tester is desirable.  Pears for are picked by
hand several times over a 7 - 20 day period depending upon maturity..

Pear, Oriental (Asian):

Most cultivars of Asian pears do resemble apples in that they have fruit
that are round and have a crunchy texture.  The Japanese cultivars tend
to be rounder in shape, while the Chinese cultivars are more oval or
pyriform (pear-shaped).  All Asian pear cultivars should be considered
self-incompatible.  Mature trees can reach heights of more than 20 feet
and 12 feet wide.  Asian pears comprise a large group of pears that are
crisp in texture and, when mature, are good to eat as soon as harvested
or for several months after picking if held in cold storage.  This
ready-to-eat feature may make them more acceptable to some people than
European pears that are usually served when soft and juicy, which
condition takes about a week to occur after removal from cold storage. 
Asian pears have been grown commercially in Asia for centuries.  In
Japan about 500,000 tons are grown and some fruit is exported to the
United States in October and November. China and Korea also grow these
pears for domestic consumption and export to the US and Canada. Most new
Asian pear plantings in California are in Fresno, Tulare and Kern
Counties.  A few plantings exist in Yakima and Wenatchee, Washington,
and others are found in Hood River and Willamette Valley in Oregon.  In
the last few years plantings of Asian pears were made in New Zealand,
Australia, Chile, France, and the eastern and southeastern United
States.  It is roughly estimated that 4,000 - 5,000 acres of Asian pears
are planted in California, Oregon and Washington.  Since 1984 about
100,000 trees (500 acres) of Asian pears have been planted every year in
California.  Most popular Oriental pears are 20th Century
‘Nijisseiki’, ‘Kosui’, ‘Kikusui’, ‘Hosui’,
‘Shinseiki’, ‘Shinko’, and ‘Niitaki’.  There are a few
cultivars of hybrid origin.  Asian pear cultivars are partially
self-fruitful but better crops are set where two or more cultivars are
planted together.  It is suggested that every 4 to 8 rows of a single
cultivar have a pollinizer row or that growers plant a block of 4 to 8
rows of a second cultivar adjacent to the first.  Asian pears should be
planted in deep, well-drained soils in a location as frost-free as
possible.  Sites that are prone to late spring frosts or provide frost
protection where late frosts are likely should be avoided.  The chilling
requirement of Asian pears is thought to be in the range of 900 to 1000
hours.  Under California conditions the fruit must be picked before 180
days after full bloom to avoid browning during storage (Table 20). 
Plant trees at least 10 to 15 feet apart in either fall or early spring.
 Plantings for standard size trees range from 140 – 380 trees/A and
for dwarf types 300 – 400 trees/A.  In California the trees are pruned
and trtained to be a vase shape - On young trees, a good portion of the
fruit is borne at or near the tips of one - year-old shoots.  As the
tree matures, most of the fruit is produced on the scaffold branches. 
These spurs have a productive life of about 10 years.  Pruning should be
done to remove about 10 percent of these terminal spurs every year.

Quince:

		Quinces are fruits closely related to apples and pears, but are of
lesser economic importance.  The plants are deciduous thorn less shrubs
or small trees.  Generally they are not over 20 feet high.  Fruits are
mostly 2 inches up in diameter, covered with pubescence.  Fruit color is
generally golden yellow.  Fruit flesh is creamy yellow and it is rather
hard with a bitter acid taste.  The most common cultivars/varieties
include ‘Champion’, ‘Pineapple’, ‘Smyrna’ and ‘Van
Deman’.  The quince has been cultivated for over two thousand years
for its edible fruit and its seed.  It is also much used as a dwarfing
rootstock for pears and some other fruits.  Bloom to harvest in about
150 days.  The fruit is harvested only by hand because the fruit is
easily bruised.  Fruit weight varies from 197 – 461 g. and seeds vary
from 15 – 42.  Yields can range from 40 – 60 t/A.  Tradionally
standard tree forms are spaced 3.5 – 5.5 m between rows and 2.5 –
4.5 m between trees and bushes 3 m apart with tree densities ranging
from 300 – 1200 trees/ha.  Cold storage conditions similar to apple
and pear are used.  Quinces are pruned similarly to pears.  It begins to
produce fruit three years after planting and orchards can remain
productive for up to 45 years.  Succeeds in most soils but prefers a
light moist fertile soil and a sunny position.  Succeeds in semi-shade
but does not fruit well in such a position.  Plants are hardy to about
-15 ° C, though the fruit seldom ripens in the north of Britain unless
it is grown against a sunny wall.  The plants require warm summers in
order to fully ripen their fruit.

Quince, Chinese and Quince, Japanese:

Chinese quinces are native to China, Indo-China, and are also cultivated
in Japan.  Chinese quince was introduced to Europe in 1796 and Japanese
quince in 1869.  It is hardy to plant hardiness zone 5 and is not frost
tender.  It is in flower from February to June, and the seeds ripen in
August through October.  The flowers are hermaphrodite (has both male
and female organs) and are pollinated by bees.  It is noted for
attracting wildlife.  The bright yellow fruit can be apple or
pear-shaped and up to 6.5 cm long x 6.5 cm wide and be as large as 17 cm
long and 8 cm broad and weigh 180 – 600 g.  It is a very ornamental
plant and is considered a good bee plant, flowering early in the year
and providing pollen and nectar, and can range in height from 10 - 20 ft
tall and 5 – 10 ft width.  It is easily cultivated as a small tree in
any reasonably good soil.  It prefers a deep moist well-drained loam,
and grows well in heavy clay soils.  Tolerates full shade but requires a
sunny position for best fruit production.  This species is hardy to
about -25°C.  It can be propagated by seed best sown as soon as it is
ripe (in February) in a sheltered position outdoors or in a cold frame. 
Germination usually takes place within 6 weeks.  Prick out the seedlings
into individual pots as soon as they are large enough to handle.  If
well grown, these seedlings can be large enough to plant out in the
summer.  Or plant them out in late spring of the following year. 
Cuttings of half-ripe wood are made in July/August or cuttings of mature
wood of the current year's growth in November in a cold frame and
layering in done in late spring or in autumn.  The Japanese quince is a
closely related species and had some medicinal uses in China and Japan
and occurs in central and south Japan.  It can grow 0.6 – 1.2 m tall
and 5 m wide.  It has been planted in Latvia in the 1970’s and in 1996
approximately 300 ha had an average yield of 12 – 15 T/ha.  A maximum
yield of 20 - 30 t/ha is possible.  Commercial production is also in
Belarus, Finland, Germany, and Poland.  The yellow (red or yellow-green)
apple shaped fruit is < 15 cm long and 8 cm diameter and weight can be
less than 50 g and contain up to 80 seeds.  Chinese quince can have up
to 120 seeds.  Both of these quinces are also grown for ornamental
purposes.  

Tejocote

	Tejocote is native to the Americas and it is hardy to zone 7 and is not
frost tender.  The flowers are hermaphrodite (has both male and female
organs) and are pollinated by midges.  The plant prefers light (sandy),
medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. 
The plant prefers acid, neutral and basic (alkaline) soils.  It can grow
in semi-shade (light woodland) or no shade.  It requires moist or wet
soil and can tolerate drought.  The plant can tolerate strong winds but
not maritime exposure.  It can tolerate atmospheric pollution.  It is
grown from seed.  Seed will germinate in the spring, though most will
probably take another year.  The tejocote prefers well-drained moisture
retentive loamy soil.  Once established, it succeeds in excessively
moist soils and also tolerates drought.  Full sun is best when plants
are being grown for their fruit.  Seedling trees take from 5 - 8 years
before they start bearing fruit, though grafted trees will often flower
heavily in their third year. 

Worker Activities (Adapted from USDA Apple and Pear Crop Timelines, AK,
ID, MI, New England, NJ, NC, WV).

Pruning:

Virtually all apple trees are pruned by hand during the dormant season. 
Most apples trees are thinned with chemical applications, but
approximately 75% of the apple acres have follow-up hand thinning in
March and April after chemical thinning (AK).  Nearly all of
Michigan’s apple orchards require some thinning of fruit to ensure a
marketable product at harvest time.  Much of this thinning is done
chemically, but there is a need to do some of the thinning work by hand.
 Hand thinning is primarily done from the middle of June until the first
of August in Michigan, but some growers will hand thin all the way up to
harvest if it is deemed necessary to ensure fruit size and quality.  A
worker will typically work 8 to 10 hours doing hand-thinning work per
day with the majority of work being done in the early summer.  It would
be typical for a worker to do 10 to 14 days of hand thinning work per
season.  Limbs are manipulated via tying to wire trellis systems or
posts inserted next to the trees or through the use of spreaders (wooden
or plastic pieces inserted between the limb and the trunk of the tree). 
This activity is usually done when branches are supple (May - August). 
Workers tie or spread branches with 2 to 5 ties/spreaders per tree and
work an average day.  Branch manipulation is typically done after the
spring apple scab season sprays are completed and between necessary
internal feeder sprays.  

	In the New England States, pruning is used to maintain a balance
between vegetative growth and fruit production that allows for adequate
penetration of sunlight, chemical treatments, and air flow.  Most
orchards are pruned once during each winter dormant season, and usually
don't begin until 3 or 4 months from the previous season's final
pesticide application.  Summer pruning, undertaken in late July and
early August, is less extensive and focuses primarily on unproductive
vegetative sprouts blocking light from ripening fruit.  Summer pruning
involves extensive contact with foliage.  Wearing protective clothing
can be problematic in summer heat, and heat stroke risk poses more
immediate and severe health concerns than pesticide exposure.  While
there is usually some flexibility for timing summer pesticide sprays,
prolonged REIs such as the 4 day REI for captan create scheduling
problems for summer pruning which must be done within a time window of a
few weeks.  

	A number of worker activities occur throughout the year that may affect
application timing, as well as the specific pesticides used.  In New
Jersey, manual pruning is done during the dormant season, usually from
late November through the middle of February.  No pesticides are applied
during that time.  Although hand thinning can be done at any time after
June, because of labor costs it is rarely a commercial practice. 
Therefore, fruit thinning is usually done with plant growth regulators
through normal spraying practices in late May.

	Growers use pruning to remove dead and damaged wood, develop and
maintain tree structure and to maintain a balance between vegetative
growth and fruit production.  Most orchards are pruned once during each
winter dormant season and may be also pruned during the growing season. 
Dormant pruning usually does not begin until several months after the
previous season's final pesticide application.  Summer pruning on
producing trees, undertaken in late June and July, is less extensive and
focuses primarily on removing current seasons’ growth, which is
shading the developing fruit.  Summer pruning can involve extensive
contact with foliage.  Wearing protective clothing can be problematic in
summer heat, and heat stroke risk poses more immediate and severe health
concerns than pesticide exposure.  However, using long-handled pruners
may minimize the amount of worker contact with foliage.  While there is
usually some flexibility for timing summer pesticide sprays, prolonged
reentry intervals (REIs) such as the 4-day REI for captan create
scheduling problems for summer pruning which must be done within a
limited time frame.  Thinning timing is critical for effective thinning
and the effective window is often a matter of days.  Chemical thinning
agents applied with the air blast sprayer often require follow-up hand
thinning and visual crop inspection requiring worker access to the
orchard and extensive contact with foliage.  Unfortunately, thinning is
concurrent with the timing for important pesticide applications for
apple scab, plum curculio, leafminers and other key pests.  Long REIs on
thinning agents, insecticides, or fungicides needed at this time create
a major obstacle to effective and profitable crop management and raises
the pesticide exposure risk factor.  Carbaryl is one of the primary
thinners used in apple orchards in North Carolina.

In Washington State, trees are pruned throughout the winter, while they
are dormant.  The orchards may be pruned any time the weather is
reasonable for the pruning crews’ comfort.  This operation is always
complete prior to the application of dormant sprays.  This activity is
one of the most labor intensive and expensive aspects of fruit
production, as trees are not uniform, and must be pruned according to
horticultural concepts.  Proper pruning maintains fruit quality and
production over the lifetime of the orchard, and is considered the key
horticultural practice.

In Idaho, trees are pruned in the winter, while they are dormant.  This
operation is usually completed prior to the application of dormant
sprays.  If not thinned yearly, most apple cultivars will develop an
alternate bearing habit, producing a heavy crop one year, then almost no
crop the next.  Biennial bearing can be reduced if a substantial number
of blossoms and small fruit are removed from the spurs on the tree
during bloom, or within two to three weeks after petal fall.  Hand
thinning is then done to remove additional fruit to achieve the desired
crop load.  Thinning the fruit by hand six to eight weeks after bloom is
a very common practice.  Because it is usually done after most flower
bud initiation has occurred, it does little to ensure return bloom. 

	European pears are harvested when "firm mature"; flesh firmness is the
most reliable indicator of pear maturity.  Firmness in the range of 10 -
15 lbs as measured by a pressure tester is desirable for most cultivars.
 Pears for are picked by hand several times over a 10 - 20 day period

Sucker Control:

About half the apple orchards in Michigan have workers in the orchard
from late June through July to remove suckers (waterspouts) arising from
the larger limbs of the tree.  This activity involves close contact with
the foliage and a worker will typically work a full day at a time (8 to
10 hours per day).  For the root suckers that sometimes arise from the
base of the tree trunk, some growers use a contact herbicide in the row
and do this task chemically.  Not all apple rootstocks produce root
suckers so this activity is only done in about 30 % of the orchards.  A
few orchardists may send a work crew through with loppers to cut off
root suckers, but this is an expensive alternative and typically
avoided.  The grower or a family member does most of the spraying. An
average 7 day interval between sprays is typical for apple pest
management programs with the majority (75 %) of pesticide application
being made in late April through mid June for apple scab prevention. 
Sprays to trees are mostly applied with ground equipment (air blast or
tower sprayers).  Herbicide applications are made with low volume
sprayers.  Typically there is an enclosed cab tractor dedicated to
pesticide applications.  Training is the selection and development of a
branching pattern on young apple trees so as to maximize the structure
and production of high quality fruit.  It is done early in the season on
new plantings and mature trees.  

	In West Virginia, workers spend about two weeks in June hand thinning
fruit and removing watersports on approximately 50 % of the apple
acreage.  Summer pruning is conducted for about two weeks in July on
approximately 10 % of the acreage.

Weed Control:

	Preemergent herbicide applications are applied in early spring,
primarily with tractor mounted spray equipment.  Postemergence herbicide
applications are made in early summer and occasionally after harvest
primarily with tractor mounted sprayers although backpack sprayers are
occasionally used (30% of Arkansas apple acres).  Row middles are mowed
throughout the growing season.  Herbicides are applied in mid April to
early May in New Jersey, but may be spot applied with a hand or backpack
sprayer during June or July, depending on the weed species being
controlled.  Mechanical cultivation may be rarely carried out 2 to 3
times a season during early May through June.  Mechanical and hand
cultivation is more common in blocks of newly planted non-bearing trees
that are not yet under a complete spray program.  Well managed orchards
usually have grass or mixed vegetation aisles that are mowed at 10 day
to 2 week intervals throughout the growing season.

Mowing is a standard orchard practice.  Mowing is done four to six times
per growing season depending on need.  Mowing involves very little
contact with treated bark and foliage as mowing equipment operators are
riding on tractors, which may have enclosed cabs.  There is potential
for operators in an open cab to brush against overhanging foliage. 
Pesticide exposure is minimal.  Fertilizer applications consist of
ground applications of dry granular fertilizer for nutrients and lime. 
Foliar spray applications of micronutrients may be used to provide apple
trees with nutrients not provided adequately in soil applications.  Most
soil applications are typically made late in the dormant season and
foliar applications may continue throughout the growing season depending
on the element and results of foliar and soil assay analysis. 
Distribution of ground-applied materials involves very little contact
with treated bark and foliage as equipment operators are riding on
tractors and pesticide exposure is minimal.  Foliar applications are
typically made in combination with pesticide sprays where proper worker
protection measures should be in place to limit pesticide exposure. 
Orchard mowing in West Virginia for weed control is conducted every 3 -
4 weeks from April through August.

Pest Control:

	Insecticides and fungicides are applied from early spring up to harvest
primarily with orchard blast sprayers.  White plastic tree guards are
typically used on every tree to protect from the gnawing of mice and
rabbits in the winter months.  These are usually applied soon after
planting.  Newly established orchards receive little to no pesticide
applications the first year of planting.  Mulches are often applied in
the spring to the base of the trees along the length of the rows. 
Depending on the thickness of the mulch and available labor, the mulch
is pulled back away from the tree trunks in the fall to prevent rodent
damage.  Both the laying down and the pulling away of mulches would
require workers to be in orchards for an average workday.  In MI,
orchard floors are routinely mowed 2 or 3 times per season to reduce
pest levels such as weeds and insects and to make the orchard conditions
more favorable for workers to walk through for required activities. 
Mowing is done with a tractor and attached mowing implement and requires
very little contact with the orchard at all.  Enclosed or non-enclosed
cab tractors are typically used.  In New England, new plantings receive
few pesticide sprays, so there are no major pesticide Reentry intervals
(REI) issues.  Mature tree training is done at a time of year when trees
typically receive little pesticide exposures for conducting summer
pruning and harvest operations efficiently, and discouraging insect
borers, voles and other pests.  Fertilization consists of ground
applications of dry fertilizer for macro nutrients and lime, and foliar
spray applications of micronutrients such as boron and magnesium to
provide apple trees with replacement nutrients for those lost to
harvested crops.  Applications may begin late in the dormant season and
may continue throughout the growing season depending on the element. 
Distribution of ground applied materials involves very little contact
with treated bark and foliage as equipment operators are riding on the
machines.  Pesticide exposure is minimal.  Foliar applications are
typically made in combination with pesticide sprays where proper worker
protection measures should be in place to limit pesticide exposure. 
Thinning timing is critical for effective thinning and the available
window is often a matter of days.  Unfortunately, thinning is concurrent
with timing for important pesticide applications for apple scab,
European apple sawfly, plum curculio, leafminers and other key pests.

Apple pollination (Adapted from Gaus, 2002 and Warmund, 2007).

Almost all cultivars of apples require cross-pollinated by honey bees or
wind with another apple or crabapple cultivar.  To attain the best fruit
set on apple trees, the king blossom (the largest and first one to open)
in the flower cluster must be pollinated.  The bloom periods of the
pollinizer and the king blossom of the apple tree must overlap.  Two
dwarf apple cultivars with similar bloom periods should be spaced less
than 20 feet apart to ensure the transfer of pollen between trees. 
Typical apple and crabapple bloom periods are shown in (Figure 2).  The
shaded area represents the bloom time.  Apple cultivars that are
suitable pollinators for other cultivars are shown in Figure 3.

Figure 2 Shows the Bloom Period of Apple and Crabapple Cultivars.

Figure 3 Shows the Apple Cultivars and Cultivars that are Suitable as
Pollinizers.  

Although some apple varieties, such as ‘Lodi’, ‘Liberty’,
‘Empire’, ‘Winesap’, ‘Jonathan’, ‘Jonagold’, ‘Gala’,
‘Golden Delicious’, ‘Rome’ and ‘Granny Smith’ may be listed
as self-fruitful, they will set more fruit on an annual basis if they
are cross-pollinated and which cultivars can be used to pollinize others
(Figures 2 and 3).  Some apple varieties, such as ‘Winesap’,
‘Stayman’, ‘Mutsu’ and ‘Jonagold’, produce sterile pollen
and therefore cannot be used to pollinate other apple varieties.  Many
nursery catalogues include pollinization compatibility charts or
recommend good apple varieties to use as pollinizers.  Manchurian
crabapple, with profuse white flowers, is commonly used to pollinate
early- to mid-blooming apple varieties, while Snowdrift crabapple is
used for mid- to late-blooming apple varieties (Figure 2). 

In commercial apple plantings, a row of pollinizer trees is often
planted between every four rows of the main variety of trees (Figure 4).
 If pollinizers are placed within the row, every fifth semidwarf tree is
a pollinizer and each pollinizer is offset in adjacent rows to stagger
them throughout the orchard block. In high-density plantings of dwarf
trees (5 to 6 feet between trees within the row), apple or crabapple
pollinizers may be planted between eight to ten trees of another variety
in the row.  Flowering crabapples are useful as pollinizers because they
take up less space than a regular apple variety and may be pruned to
grow in an upright position.  

Figure 4. Alternative Planting Plans to Ensure Cross-pollination of
Apple Trees.

Beehives are generally placed in commercial apple orchards as the king
flowers open.  If hives are brought in before this time, bees may forage
flowers of other broad-leaved plants instead of the apple blossoms.  For
this reason, dandelion flowers should be removed by mowing or by
herbicide treatment before hives are placed in the orchard. In orchards
where semidwarf trees are planted, one hive of a medium-strength colony
(15,000 to 20,000 bees) is generally sufficient per acre.  Two hives per
acre are used in high- density orchards where dwarf apple trees are
planted.  Extra strong colonies of as many as 50,000 bees have been
effective in pollinating four acres of semidwarf trees under ideal
climatic conditions.    HYPERLINK

Pear Pollination:

Most pear cultivars are commercially self-unfruitful, and need to be
pollinated to set fruit.  Nearly all cultivars that bloom at the same
time will serve as pollinators, and honey bees are the most effective
pollinator.  Pears are similar to apples, with the notable exception
that pear blossoms are much less attractive to bees, due to lower sugar
content than apple or contemporaneous wildflower   HYPERLINK
"http://en.wikipedia.org/wiki/Nectar" \o "Nectar"  nectar .  Pear
flowers produce only a small amount of nectar, which is low in sugar, so
more pollinators and bees will be needed for pears than for any other
pome tree fruit.  Bees may abandon the pear blossoms to visit dandelions
or a nearby apple orchard.  

Harvesting: 

	The entire apple crop is hand-harvested.  Hand labor activities in
Michigan apples include pruning.  In traditional free-standing orchards,
tree pruning begins as soon as some varieties are harvested in the fall,
but about ¾ of the pruning effort typically takes place after the first
of December.  Depending on the variety of apple, some trees are pruned
in the summer months to improve light penetration to the fruit for
increased fruit color.  About 25% of Michigan’s apple acres are summer
pruned.  However, the increased use of plant growth regulators is
reducing the need for summer pruning.  Depending on the overall size of
the tree, it can take anywhere from less than a minute to nearly 30
minutes to prune an apple tree.  There is sometimes a need to prune out
infected plant tissue (strikes) due to infection by bacterial fire
blight. Infection usually occurs in May and June and removal of strikes
is done typically in June and perhaps into July depending on when the
infection occurred.  This activity would require an average workday of
time, but the total time needed would depend on the severity of the
infection and the quantity of susceptible varieties in the orchard.  In
MI, harvesting is done from mid-August through the first of November,
with the majority of harvest taking place from mid-September to late
October.  Harvesting in New Jersey is done by hand, usually starting in
mid August for early cultivars, and continuing through early October for
late cultivars.  The latest insecticide applications stop by mid
September, with some fungicide use continuing until 2 to 3 weeks prior
to picking.  In most cases the greatest worker exposure to the foliage
and fruit occurs during harvest.  In North Carolina, newer cultivars
there may be up to three harvests of the tree over a period of several
weeks allowing the fruit on the tree to mature, size and color before
harvest.  Timing is critical for effective harvesting and the optimal
harvest window is often a matter of days, especially for fruit destined
for long-term storage.  Harvest occurs after the preharvest intervals
(PHIs) have been reached or exceeded.  In many cases no pesticides are
applied within at least 4 weeks of harvest.  By following the required
PHIs growers reduce the risk of pesticide exposure to their workers.  In
some cases growers provide gloves to workers to minimize the potential
for fruit contamination by the harvesting crew.  Pears for are picked by
hand several times over a 10-20 day period.

COMPARISON OF HARVESTING, JUICE PROCESSING, POSTHARVEST HANDLING, RAW
AGRICULTURAL COMMODITY (RAC), EDIBLE PORTIONS, AND PROCESSED FOOD ITEMS
FOR THE POME FRUITS:

Harvesting and Processing Apples and Pears:

	Due to the diverse and maturity dates variety of apples, harvesting
occurs at different times throughout the year.  Most apples in the U.S.,
however, are harvested in the fall (between August and October). 

Before harvesting occurs, apples and pears must be tested for "maturity"
to determine if they're ready to be picked.  This process allows
consumers to receive fresh apples of the highest quality and for
processors to select only the ripest apples for apple juice and
applesauce.  European pears are harvested when "firm mature"; flesh
firmness is the most reliable indicator of pear maturity.  Firmness in
the range of 10 - 15 lbs as measured by a pressure tester is desirable
for most cultivars.  Apples and pears that are harvested too early may
taste sour or starchy, and apples harvested too late may be soft. 
Considerations of amount of sugar, firmness and seed are looked at prior
to harvest.  Skin color determine maturity, many characteristics of the
apples is checked prior to picking.

Once the apples are confirmed to be "mature," they are picked (mostly by
hand, although some mechanical methods have been developed).  The apples
are then placed in canvas bags or lined buckets inside of large bins. 
These apple-filled bins are picked up by a forklift, loaded onto a truck
and transported to a central loading area - where apples that are
bruised, cut or have insect or disease problems are immediately removed.
 The remaining apples are stored immediately to ensure maximum storage
life.  Apples that are an "off" shape or appear to have "skin blemishes"
may not be ideal for the produce department - but they are perfectly
suitable for processing.  Similar harvesting occurs for other members of
the Pome fruit group.

Processing of Apples and Pears (US Apple Association, 2008, Apple
Products Research and Education Council, 2008, Ferree and Warrington,
2003):

Over 40 % of the U.S apple production is processed and 54 % is juiced. 
The first step in any processing procedure is handling of the raw fruit.
 During this most critical step, the Processed Apple Institute (PAI)
recommends visual inspection of all apples by a trained inspector for
"integrity and sanitary condition" and random testing for spray residues
or mold.  Apples not meeting processing standards should be rejected and
appropriate personnel informed.

Before raw apples are processed into apple juice, cider or sauce, they
are put through a handling process designed to remove external surface
dirt and topical chemical residues.  These apples are then water-washed
before processing.  This water wash is sometimes accomplished as the
fruit is water flumed from receiving stations to processing lines. 
Alternately, fruit is transported by dry conveyers through water sprays
or scrubbers before processing.  Most processing lines employ both
techniques.

Water used in the flumes or receiving pits is often recirculated and
periodically changed or refreshed.  Processors sometimes add chlorine
dioxide, hypochlorite or other chlorine compound to control microbial
buildup in recirculated water.  Apples stay in water flumes or baths for
as little as one to two minutes, or as long as 30 - 45 minutes.  Most
flumes accomplish apple conveyance to processing lines in less than 10
minutes.

Many processors employ high pressure fresh water sprays, sometimes at
several points before the fruit enters the processing line.  These
sprays provide a more vigorous cleaning, and are sometimes used along
with mechanical scrubbers, brushes or bristles rollers to remove surface
dirt.  Apples are exposed to fresh water sprays for an average of 5 - 10
seconds.  Cleaning compounds are not used in water sprays.

The cleaned apples are now ready to be processed into juice.  Using
various methods, the juice is extracted from the apples and heat-treated
(pasteurized) to kill any microorganisms that might be present.  This
heat treatment also helps improve the overall clarity of the apple
juice.  Before being placed in the appropriate container (such as
bottles), the juice may be further filtered and given an additional heat
treatment to assure safety.

	Once processed, PAI recommends that samples representing the beginning,
middle and end of each production lot be collected and stored for the
product's expected distribution or shelf line.  Samples should then be
inspected and tested by an independent contract laboratory, and any
product not meeting quality standards should be identified and handled
accordingly.  The standard packing line procedures are used for pear -
hydrocooling, washing, culling, waxing, sorting, and packing.  Quality
grade is based on size and appearance of skin; greater prices are
obtained for larger fruit and those with minimal surface blemishes. 

Processing Studies for Apples and for Their Juice, Cider, and Sauce. 
(Adapted from US Apple Association, 2008, and Neil Ewing, National Food
Processors Association, 1992 

The required processing studies for apple are in a series of processing
study protocols from the National Food Processors Association submitted
to Dr. Debra Edwards US EPA, OPP, CBTS (Ewing, 1992).  The procedure
simulates commercial practices and discusses the processing of apple
samples starting with raw unwashed apples which are also processed
further into wet pomace and juice.  The procedure involves using
unwashed whole apples are sampled for residues.  For apple juice, wash
the apples through a flume/spray to remove surface dirt.  Apples are
peeled, cored, and sliced and ground or pressed through a screen.  The
juice is separated from the pomace.  The juice is clarified and heated
to 100 – 120° F.  The filtered juice is heated to 190 °F for canning
and the juice sampled for residues.  If applesauce samples are needed
the sliced apples are cooked with water at 212 °F for 10 minutes and
the cooked apples are then pressed through a screen and reheated for
canning and sampling. If data is needed on apple slices they are
blanched with water at 180 – 185 °F for 1 – 2 minutes and the
slices are canned with water at 170 – 180 °F and sampled after
canning for residues.  

Fresh apple cider or sweet apple cider is made locally by farmers with
their apples that do not meet fresh standards.  Cider is made by
pressing apples to produce juice which is then fermented.  It must be
refrigerated and has a storage life of 2 – 3 weeks.  Fermented or hard
cider is a shelf stable product that is fermented to increase its
alcohol content.  Cider apples are distinct cultivars and are chosen for
their fruit qualities.  The cultivars are classified into four groups
based on sweetness, tannin content and acidity.  Tannin content is
desired in cider apples which gives apples their bitter and astringent
taste.  Some of the apple cider cultivars are: bitter sweet –
‘Ashton bitter’, ‘Osier’, and ‘White Norman; sharp’ –
‘Crimson king,’ ‘Federick’, and ‘Tom putt; sweet,’ –
‘Court royal’, ‘Labret’, and ‘Sweet coppin’; and ‘Bitter
sharp – Foxwelp’, ‘Genet Moyle’, and ‘Stoke red’.

	Apple sauce is produced by peeling and coring apples and then slicing
them into pieces and precooked usually by pressing through a pressurized
steam tunnel for 4 – 5 minutes until the temperature reaches 96°C. 
After cooking it is passed through a finishing machine to remove any
coarse materials.  U.S. applesauce standards are based on color,
consistency, absence of defects, flavor, and finish.  Apple butter and
slices are considered specialty items and are less than 1% of total
apple products.  Yields of apple slices vary from 45 (2 1/2 in) 64 mm
apples to produce 10 lb of slices, while only 26 (3 inch) 76 mm apples
make 10 lb of slices.  

Comparison of the Raw Agricultural Commodities (RAC) and Processed
Commodities for the Pome Fruits (see Table 21).

	The raw agricultural commodities (RAC) for the Pome fruit group are
similar (Table 21).  Only apple requires the processed commodity for
juice and the only livestock feed commodity for wet apple pomace.

	Other uses for the specific pome fruit commodities are discussed under

and marketing standards for members of the Pome fruit group 11.

LIVESTOCK FEED ITEMS: 

	Wet apple pomace is the only significant animal feed items associated
with the Pome fruit crop group 11 (Table 21).  It is used as a source of
carbohydrate concentrate and fed up to 10 % of the dairy cow diet.  The
wet apple pomace is a byproduct of the apple processing industry, and is
the processed item which remains after cider has been expressed from
small whole apples, and the stems, cores, and peelings remaining after
preparation of apple juice and sauce for human consumption.  It is
produced only in apple growing/processing areas, usually fall until
mid-spring.  Some is fed to growing beef, beef cows, and lactating and
non-lactating dairy cows as available, but the supply is limited and it
is not hauled any long distance because of shipping costs.

CROP ROTATIONS FOR THE POME FRUITS:

	The members of the Pome fruit group are not rotated because of their
long productive life spans at the same location most pome fruit orchards
are kept at the same location for at least 25 years.  Dwarf apple
orchards are productive for 10 years, while semi-dwarf cultivars for <
25 years and standard size cultivars for > 25 years, and orchards are
replanted in the same area.  The growth and development of pome fruit
trees including size, years to a maturity, and yield/tree are shown in
Table 22.  For apples the yield/tree for a semi- dwarf ranges form 5 –
10 bu/tree, while the standard size is 10 - 25 bu/tree.  The standard
European pear bears one – two bushels more than dwarf varieties/tree.

PEST PROBLEMS FOR THE POME FRUIT CROPS:  (Developed from USDA Crop
Profiles from CA, CT, ME, MA, NH, NY, OR, RI, VT, and New England (NE)
Extension Bulletins, Fajardo 2006a, and Research Literature).  

There are several common pest problems that occur among the pome fruits.
 The most important pest problems associated with this group of
commodities are plant diseases including postharvest diseases, as well
as some insects and mites.  The following are the list of important
insects, mite, diseases, weeds and vertebrate pest problems of the pome
fruits (USDA Crop profiles 2007).

	Proposed pome fruit commodities that are being added to the crop group
share many of the same pest problems because of their similar cultural
practices and their highly desirable fruits to many pests.  

	The members of the Pome Fruit Crop Group share many of the same pest
problems since they are all members of the same botanical family the
Rosaceae.  Because of the similarity in the botany, cultivars and
cultural practices among these crops, they have similar pest problem. 
Availability of a similar set of pest control options for the Pome fruit
group would be useful in promoting integrated pest management (IPM)
strategies to reduce the need for multiple applications and to avoid
pesticide resistance problems.  Some of the pests affect the external
appearance of the fruit some from damage by feeding on the leaves or
buds, and some by reducing postharvest keeping qualities. Weeds can
reduce tree growth by up to 50 % in young trees.  The weeds also harbor
insect, disease hosts and provide protection for vertebrate pests as
well as compete for nutrients and moisture.

	Pome fruit orchards have many weed control problems that must be
controlled to ensure adequate yields and harvesting efficiencies.  This
pome fruit group shares a multitude of insect, disease, and nematodes. 
Weeds include grassy and broadleaf such as annual, biennial, and
perennial weeds such as Johnsongrass, Bermudagrass, morningglory,
nutsedge, quackgrass, crabgrass, Canada thistle, pigweed, poison ivy,
and lambsquarter.  Animal pest problems include meadow voles, deer,
squirrels, ground hogs, and rabbits that often knaw at the bark and
girdle the tree. 

	For apples insect pests include plum curculio as a serious pest; as
well as apple maggot, rosy apple aphid, and codling moth (Table 23). 
Plant diseases include fireblight, Gymnosporangium rust, apple scab,
bitter rot, Phytophthora crown collar rot, and black spot, powdery
mildew, fly speck, sooty blotch, post harvest diseases such as Botrytis
(Table 24).  Insects and plant diseases cause leak loss, twig loss, tree
vigor loss, flower and fruit loss, tree death, and yield losses.  Apples
also have several nematode pests such as the dagger, root knot, and root
lesion nematode.  Vertebrate problems include mice, pocket gophers,
rabbits, raccoons, ground hogs, and deer that knaw at the roots, foliage
or twigs, and girdle trunks.

	Pear insect problems include codling moth, pear psylla, European red
mite, two-spotted spider mite, Pacific spider mite, McDaniel spider
mite, and leafrollers (Table 25).  In California, the coddling moth is a
very important pest due to a lack of effective biological control
systems.  Plant diseases include pear scab, Venturia pirina, fire
blight, Armillaria root rot (oak root fungus), post-harvest diseases
caused by fungi (gray mold caused by Botrytis cinerea.  The more
important post-harvest diseases of pears are powdery mildew, blue mold,
Alternaria rot, and mucor rot.  Nematodes include the Dagger and root
lesion nematode.  Vertebrate problems are similar to apples in that
meadow voles will knaw at the bark and roots and can girdle the trees.

	The flowering crabapples are relatively undamaged by most insects but
mmajor insect pests include various types of caterpillars, leafhoppers,
leaf-rollers, leafminers, and Japanese beetles, but these pests often do
not cause significant damage to the trees.  Plant diseases include apple
scab, frog-eye leaf spot, and fire blight.

	For loquats, infestations of black scale may appear, and fruit flies
are serious pests in areas where they are problem.  Plant diseases
include fire blight caused by Erwinia amylovora is a major disease of
loquat in California; crown rot caused by Phytophthora and cankers
caused by Pseudomonas eriobotrya are also occasional problems.

	For mayhaws, insect pests are similar to apples and include plum
curculio, hawthorn lace bug, flower thrips, roundheaded appletree borer,
whitefringed beetle, leafminers, scales and mealybugs.  Plant diseases
include quince rust, (Gymnosporangium clavipes), fireblight (Erwinia
amlovora), and brown fruit rot (Monilia johnsonii).  

	Many diseases also infect quinces and include fireblight, rust, wilt,
coddling moths, woolly aphid, and pear leaf blight.  Medlars also have
similar pest problems such as fireblight, rust, powdery mildew and brown
rot.  

COMPARISON OF POTENTIAL RESIDUE LEVELS IN THE POME FRUITS:

	Magness, Markle, and Compton in 1971 classified food and feed crops
based on predicting the potential for pesticide residues based on
exposure of the edible parts to applied pesticides, which led to the
development of the crop groups.  The majority of the pome fruits (apple,
pear, and quince) were classified in the Fruit Crops Category III. 
Category III include the pome fruit crops with fruits mostly medium to
large, peel generally discarded in processing, but may be eaten with the
fresh fruit.  Category III fruit crops will have moderate exposure of
edible parts to applied pesticides.  The crabapple is placed in Fruit
Crops Category IV since it has somewhat greater exposure of edible parts
to pesticides than in Category III, because peel is commonly consumed or
in contact with the mouth or when pressed for juice.  Fruits are medium
to small and the peel is commonly consumed.  

	We expect that all proposed members of the pome fruit crop group will
have similar residue levels based on similarities of the raw
agricultural commodities (RAC’s), cultural practices, and pest
problems.  A comparison of established tolerances on pome fruit
commodities also supports that residue levels will be similar between
members of the crop group and subgroups (See Tables 26, 27, and 28). 
The proposed representative commodities cover over 99 % of the total
pome fruit production in the U.S., and they also tend to be an equal or
more conservative estimate of tolerances and potential residues.  Based
on existing tolerances in 40 CFR and the USDA FAS MRLdatabase, a
comparison of these tolerances for the representative commodities is
listed in Table 27 for the U.S., Codex MRL’s, and the European Union
(EU).  In several cases the U.S. tolerances are the same or higher than
those established in the EU and/or in Codex.  Tables 28 contain
tolerances established in the U.S. on the representative commodities
apple and pear and shows the tolerance levels are remarkably similar.

REQUIRED NUMBER OF CROP FIELD TRIALS FOR CROP GROUP 10 AND COMPARISON OF
EPA CROP PRODUCTION REGIONS WITH THE NAFTA CROP PRODUCTION REGIONS:

	A reevaluation of crop production data from the 2002 USDA Agricultural
Census shows that the amended Pome fruit crop group 11 will not require
additional field trials because the acreage for apple and pear have not
significantly changed from the 1991 data used in the current field trial
guidelines (EPA OPPTS 860.1500).  The suggestive current number of crop
field trials for the Pome fruit group 11 is listed in Tables 29, 30, 31,
and 32, respectively.  The only difference in the 2002 AG Census shows a
shift in apple production from 2 trials in Region 2 to one and an
increase of one trial in Region 11 (Table 31 and 32).  Pear field trials
have not changed over this time.  It should be noted the number of field
trials in Table 32 is based on new AGCensus data only and will have to
be assessed by an internal NAFTA workgroup for any changes in field
trial regions.  Table 32 is not approved by EPA or PMRA.  Locations of
the field trial regions where pome fruits are grown are in Table 30).

	Currently if a crop group tolerance is not being pursued the number of
field trials for the individual commodities apple and pear is 16 and 8
respectively for a total number of 24 trials (Tables 29 and 31).  The
number of field trials for the representative commodities if a Pome
fruit group tolerance is proposed is 12 field trials for apple and six
field trials for pear for a total of 18 trials (Table 29).  

Efforts to update the NAFTA regions will begin in 2009.  Any future
conflict in testing between regions can generally be resolved by having
the ChemSAC review the test protocol regions before residue trials are
initiated and any differences can also be resolved by input from the
International Crop Grouping Consulting Committee (ICGCC) and Canada,
PMRA.

CODEX CLASSIFICATION OF PROPOSED COMMODITIES AND EPA FOOD AND FEED
COMMODITY VOCABULARY:  See Table 33.  Comparison of Pome Fruit Crop
Groups:  Codex (001) and EPA (10).   (Data prepared by Dr’s.
Yuen-Shaung NG, Hong Chen, and Dr. Bernard A. Schneider, US EPA and USDA
IR-4, 2004, 2007).

Another important aspect of crop grouping is the harmonization effort
with the Codex Classification of Foods and Animal Feeds.  The current
EPA crop group for Pome fruit group 11 is similar to the corresponding
Codex Pome fruits (Crop Group 002).  The Codex Group 002, Pome Fruits,
consists of eleven commodities including six of the seven commodities in
the current EPA crop group 8 (Table 33).  The only exceptions are mayhaw
which is in the U.S. crop grouping system and medlar which is in the
Codex system.  The U.S. Crop group is also proposing to add five new
commodities: azarole, Chinese quince, Japanese quince, medlar, and
tejocote that are not yet in the Codex classification system.  EPA will
change the name of the commodity Oriental pear to Asian pear based on
the international usage of Asian pear as a trade name for this
commodity.  The eleven Codex commodities really consist of seven
distinct commodities with the rest being multiple entries, or varieties
of cultivar of other commodities listed.  The scientific name for
Oriental pear in the Codex system is incorrect Pyrus pyritolia should be
Pyrus pyrifolia (Burm. f.) Nakai var. culta (Makino) Nakai and the
scientific name for pear should be Pyrus communis L. not Pyrus
pyrifolia.  

Note that the current Codex crop group does not have representative
commodities.  A revision of the Codex Classification is underway with
consideration to include adding new commodities, creating subgroups, and
selecting representative commodities.  The IR-4/EPA Crop Grouping
Working Group and the International Crop Grouping Consulting Committee
(ICGCC) are making every effort to cooperate with the Codex revision
effort.  The proposed revised Pome Fruit Group was discussed within the
ICGCC workgroup which includes representatives from the Codex Revision
workgroup.  The expanded Pome Fruit Group and the representative
commodities proposed in this petition would facilitate the harmonization
of the U.S. and the Codex crop classification systems.  In the next
proposed revision to the Codex Classification of Foods and Animal Feeds
we would expect these changes to be considered as additions to their
Pome group in the harmonization effort that Bill Barney, USDA IR - 4 is
coordinating with the Codex delegation.  Therefore, this proposal will
not only increase harmonization with the Canadian and NAFTA crop
grouping system, but it is compatible with the international system of
Codex.  The Food Quality Protection Act of 1996 placed increased
emphasis on using Codex MRLs in setting tolerances for pesticides in the
U.S.

PREPARATION, FOOD FORMS, COOKING METHODS, FOOD FORMS, SPECIFIC USES,
MEDICINAL USES, FRUIT YIELDS, AND MARKETING STANDARDS FOR MEMBERS OF THE
POME FRUIT CROP GROUP:

Preparation and Cooking Methods for the Pome Fruits:

	The twelve commodities in the proposed amended Pome fruit crop group
are all long living perennial angiosperms (flowering plants) that are
deciduous small trees that produce an edible fruit called a pome.  

	The members of this crop group have similar uses, and all are consumed
fresh or consumed cooked or raw in various recipes including salads,
jellies, and juices.  They can be used fresh or in a dehydrated form. 
Some of these pome fruits also have medicinal properties.  The fact that
these pome fruits are in the same family with similar biological and
cultural aspects suggests they should also encounter similar pest
problems and hence have similar needs for pest control products in
similar use patterns.  The cooking methods and food forms used to
prepare pome fruits are shown in Table 43.  Pome fruits have many food
and nonfood uses.  They also have ornamental landscape uses, plant
extracts for medicinal uses, and uses as dyestuffs.  Specific uses for
some of the Pome fruits will be discussed below.

Specific Uses of Pome Fruits:

Apple 

	Apples have many food uses and can be eaten fresh, eating, canned,
sauce and slices, juice, dried, frozen, vinegar for culinary uses (Table
34).  Parts of the plant consumed are mainly fruit flesh, but peel often
eaten on fresh fruits.  Peels and cores from processing plants may be
used in vinegar, or as livestock feed.  Pulp and peel from juice
processing are used as livestock feed.  Apples have a broad spectrum of
food uses: pies and cakes, jams, apple sauces and juices, apple butter,
dried apples, and much more.  Most apples can be eaten out of hand just
as they are or they can be cored, peeled and sliced first.  Generally,
if they are going to be cooked or used in other food dishes, the apples
must be prepared in some manner and cut in many shapes and sizes, such
as rings, slices, wedges, and triangles.  They can also be diced,
julienne and shredded.  The end use of the apple will determine how it
is to be cut.  Larger cut pieces are often used in recipes where the
apple will be cooked in some manner, while smaller pieces are used in
recipes where the apple will not be cooked, such as in a salad.  When
fresh apples are peeled or cut open, the apple's cells are exposed and
react with the oxygen in the air.  The oxidation reaction that occurs is
what turns the apple brown.  When an apple is bruised the same type of
reaction will occur.  If an apple is damaged by being hit or dropped,
the apple's cells in that area are damaged and exposed to the air inside
the apple, causing them to turn brown.  When preparing apples for use,
an anti-browning solution such as ascorbic acid should be used to
prevent the apples from turning brown.  Apples can be cooked using many
methods.  They can be cooked on their own and eaten as a side dish or
added with other ingredients to create a main dish.  Cooked apples are
used with meats, such as ham, pork, and poultry.  There are many recipes
and different techniques used to bake apples. The apples may be left
whole, unpeeled, and cores removed, or they may have a portion peeled
and skins left on the remainder.  Some recipes will call for the apples
to be cut in half first and then the cores removed.  Generally the
recipe will have some type of filling that is added to the cavity of the
apple before baking.  The filling may be as simple as butter and brown
sugar or it may consist of a mixture of several ingredients, such as
butter, sugar, brown sugar, syrup, honey, apple juice, water, cinnamon,
nutmeg, dried fruit, and nuts.  Apples may also be cut into rings,
wedges, or slices for frying.  They may also be peeled or unpeeled,
depending on the recipe.  Apples are generally fried in butter and
either white sugar or brown sugar, which helps them keep their shape. 
Some recipes will call for other ingredients, such as cinnamon, nutmeg,
salt, egg, and water.  Applesauce is a popular food that is simple to
cook and made with few ingredients.  The basic ingredients consist of
cooking apples, sugar and water.  Other ingredients, such as cinnamon,
nutmeg, cloves, lemon juice or zest, and apple cider, can be added to
enhance the flavor.  Drying apples will remove moisture from the apple,
leaving it with a concentrated flavor.  Dried apples make a sweet
nutritious snack and are easy to store.  They can also be reconstituted
for use in sweet and savory dishes.  There are several methods that can
be used to dry apples.  They can be sun dried, oven dried, or dried in a
dehydrator.  Apple juice has surpassed orange juice consumption by
children in the USA.  A medium-sized apple contains about 80 calories,
and is unusually high in fiber: generally about 5 grams per fruit
(mostly from pectin).  In 2001, United States consumers ate an average
of 45.2 pounds of apples and processed apple products.  About 60% are
eaten fresh (about 60 - 70 apples, or more than 1 per week).  The
utilization is as follows: fresh is 55 - 60%; canned is 12 - 15%; dried
is 2 - 3%; frozen is 2 - 3%; with juice, cider; sauce, vinegar; another
20 - 25%.   The wet apple pomace can be fed to beef or dairy cattle
within areas close to the processing plants.  The apple wood is also
used in smoking foods.

Azarole:

	Azarole fruit are small fruits used as raw or cooked in pies,
preserves.  The fruit can be used fresh or dried for later use.  In warm
temperate areas the fruit develops more fruit sugars and has a fragrant
sugary pulp with a slightly acid flavor.  It can be eaten out of hand. 
In cooler zones, however, the fruit does not develop so well and is best
cooked or used in preserves, jams, jellies, butters, candid fruit
slices, and compotes.  It is also made into a sweet wine, juice for
fruit drinks and soft drinks.  The fruit is very variable in size and
color; it is up to 25 mm in diameter.  There are up to five fairly large
seeds in the centre of the fruit, these often stick together and so the
effect is of eating a cherry-like fruit with a single seed.

Crabapple:

	There are varieties such as ‘Hyslop’ and ‘Red Siberian’ that
produce relatively large fruit that can be used as a food crop and are
processed for cinnamon apple rings.  Fruit is processed and used for
apple jelly, apple sauce, tarts, and apple butter.  The pulp after
making jelly can be fermented into cider or added to breads, cakes, and
cookies.  Fruit can also be used as a garnish.  Crabapples trees are
used for pollinators in apple orchards and as a showy ornamental crop. 
The Western crabapple is eaten fresh or stored under water, or under a
mixture of water and oil, in cedar wood storage boxes.  The fruit can be
eaten raw or cooked.  The whole fruit is processed in pickling and
preserving.  The fruit can be cooked, with core tissue and peel sieved
out.

Loquat

	The loquat is used fresh eating out of hand or in fruit salads, and it
is also used for juice or wine or cooked for desserts, jams, jellies,
pies, sauces, drinks, candid fruit, sauces or preserves.  Loquat pie if
made from fruit not yet ripe tastes like cherries.  Only the inner pulp
is consumed.  Most often eaten fresh, but due to bruising, are rarely
marketed this way.  Loquats are also found canned in heavy syrup. 

Mayhaw

	Mayhaws are sorted by removing decayed fruit and trash, and wash
thoroughly before food preparation.  To make juice and jelly, a gallon
(4 quarts or about 4 1/2 pounds) of mayhaws cooked they are covered with
3 quarts (12 cups) of water.  Bring to a boil, cover and cook gently for
about 30 minutes.  Cool and drain juice first through a colander,
pressing fruit lightly with the back of a spoon.  Then strain the juice
through two or three thicknesses of damp cheesecloth, or through a jelly
bag or a clean thin white cloth.  The sediment which settles to the
bottom is discarded.  One gallon (4 quarts) or about 4 1/2 pounds of
mayhaws will yield about 12 cups of strained, flavorful juice, enough
for three batches of jelly.  It is used mainly for jellies, preserves,
and also in wines and syrup.  In China it is available as jelly, jam,
gelatin, fruit rolls, soft drink mixes, dried slices for tea, and wine. 
They can be canned or frozen and used to make jelly year around.

Medlar

	Medlars are used for fresh eating out of hand or used for beverage,
syrups, dessert, or preserves.  They can be baked whole or roasted, or
made into tarts, jams and jellies, and occasionally made into cider. 
The plant is often used as an ornamental.  The main part consumed is the
inner pulp only and the skin and seeds are discarded.

Pear

	Pears are used primarily as a fresh fruit, and they are also processed
as canned, dried, pickled, baked, baby food and beverages.  They are
also made into marmalades, preserves, fruit nectars, puree, juice, and
pies, or cider.  Only the inner flesh is used in canned or baby food
preparations.  The juice is now extensively used to add to canning of
many fruits.  The peel may be consumed when eaten fresh and is retained
on dried fruit.  The core may also be used to make vinegar.

Oriental pear

	The Asian or oriental pear has similar uses to pears.  

Quince

	Quince is rarely eaten fresh, mostly utilized for jelly and other
preserves.  The pineapple quince must be cooked before using.  It is
primarily eaten stewed, preserves with pears, stuffed, or made into
pies, marmalades, jams, jellies, liquors, wine, fruit leather,
conserves, and candy.  The flowering quince is widely grown as an
ornamental, often sets some fruit that also may be utilized for jelly. 
When grown in warm temperate or tropical climates, the fruit can become
soft and juicy and is suitable for eating raw.  Internal flesh, but all
cooked prior to pressing for jelly.  The flowers are also edible.  In
cooler climates such as Britain, however, it remains hard and astringent
and needs to be cooked before being eaten.

Quince, Chinese and Quince, Japanese:

	The fruit is cooked or parboiled, mashed after seeds are removed, and
then mixed with a honey and ginger to make a beverage.  It is harsh and
acid raw but fragrant when cooked.  Used for jams, jellies, conserves,
and as a flavoring with cooked apples.  It is generally used for
preserve or fruit wine.  

Tejocote

	The fruit is used raw or cooked, often used in preserves, jellies, and
jams.  When stewed they must have the skins removed by boiling with wood
ash and boiled in hot syrup like candy apples.  Also used as a flavoring
for rum, tropical fruit punch, and carbonated drinks. 

MEDICINAL USES OF POME FRUITS: 

	There are several medicinal uses of the pome fruits are they are
discussed below for each of the pome fruits.

Apple 

	Eating two apples or drinking 12 ounces of apple juice daily was shown
to reduce build-up of arterial plaque. The bark and roots of most Malus
species contain phloretin, and antibiotic-like compound that acts on
certain bacteria

Azarole:

Although no specific mention has been seen for this species, the fruits
and flowers of many hawthorns are well-known in herbal folk medicine as
a heart tonic and modern research has borne out this use.  The fruits
and flowers have a hypotensive effect as well as acting as a direct and
mild heart tonic.  They are indicated in the treatment of weak heart
combined with high blood pressure.  It is normally used either as a tea
or a tincture. 

Crabapple

The bark of Western crabapple was used, alone or with other plant
products, for a variety of medicinal treatments for the eyes and for the
stomach and digestive tract.  The Western crabapple is used by several
native North American Indian tribes to treat a variety of complaints. 
The trunk, bark and inner bark are antirheumatic, astringent, blood
purifier, cardiac, diuretic, laxative and tonic  The trunk, bark and
inner bark are antirheumatic, astringent, blood purifier, cardiac,
diuretic, laxative and tonic.

Loquat:

	Leaves and fruit have been used for medicinal purposes.  It has claims
to reduce inflammation, bronchitis, and lung congestion.

Mayhaw:

	Medicinal products used for back pain, dysentery, high blood pressure,
high cholesterol, and cure diseases.  The Meskawakis Indians used unripe
Crataegus tomentosa fruit for bladder ailments; these fruit also have
hypotensive (lowers blood pressure) and antiarrhythmic activity
(counters irregular heartbeat).  Seeds of hawthorns are sometimes boiled
or roasted, and made into a coffee-like beverage (Sorbus fruit also used
for this).  Crataegus oxycantha leaves are substituted for tobacco and
smoked, causing a mild stimulant effect.

Medlar:

	There is a single recommendation of a remedy for kidney stones that
proposes that Medlar leaves be boiled and drunk as tea until the stone
is ejected. Although the fruit is edible, it is not considered GRAS
(Generally Recognized as Safe). 

Quince

	The stem bark is astringent and it is used in the treatment of ulcers. 
The seed is a mild but reliable laxative, astringent and
anti-inflammatory.  When soaked in water, the seed swells up to form a
mucilaginous mass.  This has a soothing and demulcent action when taken
internally and is used in the treatment of respiratory diseases,
especially in children.  This mucilage is also applied externally to
minor burns etc. The fruit is antivinous, astringent, cardiac,
carminative, digestive, diuretic, emollient, expectorant, pectoral,
peptic, refrigerant, restorative, stimulant and tonic.  The unripe fruit
is very astringent; syrup made from it is used in the treatment of
diarrhea and is particularly safe for children.  The fruit, and its
juice, can be used as a mouthwash or gargle to treat mouth ulcers, gum
problems and sore throats.  The leaves contain tannin and pectin. 
Tannin can be used as an astringent while pectin has a beneficial effect
on the circulatory system and helps to reduce blood pressure.

Quince, Chinese and Quince, Japanese:

The fruit is analgesic, anti-inflammatory, antispasmodic, astringent and
digestive.  A decoction is used internally in the treatment of nausea,
joint pains, cholera and associated cramps.  The dried peel can be used
for expectorant and antidiarrheic.

Tejocote

	The fruits and flowers of tejocote is well-known in herbal folk
medicine as a heart tonic

POME FRUIT EQUIVALENTS AND YIELDS:

	Table 35 shows the pome fruit equivalents for an individual fruit, for
example one large apple (242g) yields ¾ cup of apple sauce and 1 3/8
– 1 1/2 cup of sliced apples.  One medium apple yields 3/4 cup of
apple juice or 1/2 cup of applesauce 1 1/4 apple yields one serving of
apple juice (8 oz. or 240 ml) which equals 120 calories.  

Table 35.  Pome Fruit Equivalents and Equivalents and Their Food Yields
(U.S. Apple Association).

		Sixty-four percent of the 2005 U.S. apple crop was eaten as fresh
fruit, 36 percent was processed into apple products, and less than 1
percent was not marketed.  The average consumer ate about 65 apples or
22 lb/person annually.  Of the apples that were processed, 51 percent
were used for juice and cider; 5 percent were dried; 7 percent were
frozen; almost 2 percent were used to make fresh apple slices and 32
percent were canned.  Other uses included baby food, apple butter or
jelly, and vinegar.

	USDA MARKETING STANDARDS FOR POME FRUITS:

The USDA Agricultural Marketing Service (USDA AMS USDA AMS 1955a: USDA,
AMS. 1955b, and USDA AMS 2002) has established standards for marketing
many of the pome fruits.  For apples the U.S. grades are U.S. extra
fancy, U.S. fancy, and U.S. No. 1 based on color requirements, freedom
from decay, disorders, freeze injury, visible water core, blemishes, and
lack of insect damage as well as firmness of the fruit.  There are
minimum color standards specified for twelve apple varieties such as Red
delicious, ‘Empire’, ‘Jonathan’, and ‘Rome Beauty’.  Grade
for ‘Red Delicious’ apples is based primarily on the percentage of
red color.  Extra Fancy grade must have 70 % red color, while fancy
grade must be 40 %.  ‘Golden Delicious’ colors range from dark green
to yellow.  Size standards are based on diameter or weight in grams. 
Red delicious size and weight ranges from 2 1/8 inches diameter or 65
grams to 2 3/4 inches or 139 grams.  ‘Red delicious’ size and weight
ranges from 2 1/8 inches diameter or 65 grams to 2 3/4 inches or 139
grams.  Fall, winter, and pear standards are U.S. No. 1 and U.S. No. 2
based on variety, free from decay, scald, freeze and insect injury, and
mechanical injury.  Pears can vary in size from 2 ½ minimum to 2 ¾
maximum inch traverse diameter.  Quality standards for pears also depend
on color and freedom from blemishes.  Approximate apple sizes can vary
between varieties with a small size being 2 1/4 inch diameter and 4 oz
in weight (Table 36).

Table 36.  Approximate Apple Sizes (Size will vary between varieties)

Size	Diameter	Approximate Weight	Apples per Pound

Small	2 1/4"	4 oz.	4

Medium	2 3/4"	5 oz. to 7 oz.	3

Large	3 3/4"	8 oz. or more	2



AVAILABILITY AND STORAGE LIFE OF THE POME FRUIT CROP GROUP MEMBERS IN
THE MARKETPLACE:

	Pome fruits are widely available in the marketplace both from domestic
production and imports.  The available and peak production periods for
apples, pears, and Asian pears in the marketplace are shown in Tables
37, 39, and 41, respectively.  Washington State and Canada have apples
available during the whole year (Table37).  Apple variety availability
is shown in Table 38 with ‘Red Delicious’, ‘Golden Delicious’
and Granny Smith’ are available during the whole year.  Specific
descriptions of each apple variety and their uses as a fruit are
discussed in Appendix II.  Pears are available for the whole year from
Washington and Oregon (Table 39).  In most cases based on U.S.
production and imports pome fruits are now available all year around.

	Pears rank second to the apple as the most popular U.S. fruit.  They
can be eaten and used in a lot of similar ways as the apple.  One
distinct feature of the pear besides the shape is the soft texture. This
soft texture is the result of the starch converting to sugar after being
picked from a tree to ripen.  With the numerous varieties and extended
growing seasons, pears of all sizes and colors are available year-round.
 There are several varieties of pears including ‘Anjou’,
‘Bartlett’, ‘Bosc’, ‘Comice’, ‘Forelle’, and
‘Seckel’ (Tables 39).  These fruits have a sweet, rich flavor and
come in a variety of colors including green, golden yellow and red. 
Among these varieties there are only subtle differences in flavor and
texture.  Pears come in a variety of shapes, sizes, and colors from tiny
‘Seckel’ to long-necked ‘Bosc to the colorful ‘Red
Bartlett’s’.

The ‘Green Anjou’ is available from October through June (Table 40).
 It is firm and green, even when ripe; this large, thin-skinned
yellowish-green pear is best eaten fresh.  When slightly under ripe, it
can be baked or poached, but once it ripens, its sweet, mellow flavor
and juice make it an excellent choice for salads and snacks.  The ‘Red
Anjou’ is available October through May and has much the same flavor,
use and texture as the ‘green Anjou’.  The ‘Red Anjou’ are
generally dark, maroon red in color show little to no change in color as
they ripen, which is another characteristic shared with their ‘Green
Anjou’ counterparts.  The ‘Red Anjou’ is recognizable for their
near egg-shaped appearance.  The ‘Yellow Bartlett’ is available
August through December and is one of the most common and popular pears.
 This large, bell-shaped all-purpose pear has a yellow skin sometimes
blushed with pale red.  It is very sweet, juicy, aromatic and perfect
for salads, eating fresh, and excellent for canning or cooking.  It
holds its shape and flavor in baking and cooking.  The ‘Red
Bartlett’ is available August through December and ha s a firm, bright
red skin, very sweet and juicy when ripe.  This variety is a bit
smaller, with the same flavor, texture, and use as ‘Yellow
Bartlett’s’.  They make a good choice as a color accent in a
fresh-fruit dessert or salad.  The ‘Bosc’ is available August
through April and has a firm dense, yet tender flesh with brown skin
that has a sweet and spicy flavor.  Its dense flesh makes it good for
baking and cooking.  Color doesn't change as it ripens, excellent for
baking.  Its mild, not-too-sweet flavor is useful for microwave recipes,
salads, and snacks.  The ‘Comice’ is available August through March
and is hard, green, and rounder than a Bartlett, but similar in flavor
and texture.  It is one of the largest, sweetest and juiciest varieties.
 Best used fresh in salads, served as a dessert pear, or as an
accompaniment with cheese.  The ‘Forelle’ is available September
through February and is slightly larger than a ‘Seckel’, with
freckled skin and a red blush.  They are an excellent snack or lunch-box
pear, sweet, juicy, and crisp.  The ‘Seckel’ is available August
through February and as a small pear that has an ultra-sweet flavor, so
sweet in fact they are often called "sugar pears."  Maroon and olive
green in color, with no color change when ripened.  They are also a good
choice for children's snacks, for pickling, or as a garnish.

	Asian pears are available from California from July through February.
(Table 41).  Oregon and Washington produce Asian pears from July –
October.  The Imports of Asian pears from Chile are available during
March – April, while Japan and New Zealand are available from July –
October.

Storage Life of Pome Fruits:

	The pome fruits have relatively long storage lives (Table 42).  Apples
can be stored for one month to a year at temperatures ranging from 30 -
40° F, while pears can be stored for two to seven months .at
temperatures ranging from 29 - 31° F.  Quince has the shortest storage
times at two – three months.  The pome fruits are climacteric fruits
that respond to ethylene gas and will ripen in storage.  Pears are
stored just below freezing up to several months, and then ripened for a
few days at 70 - 75° F prior to consumption or canning.  Unlike apples,
pears are not subject to chilling injury.  'Bartlett' can only be stored
for a few months, whereas 'Anjou' and 'Winter Nelis' can be stored for 5
- 7 months.  If pears are unripe, place them in a paper bag at room
temperature for 2 to 3 days or store them in a ventilated fruit bowl in
a cool, dark place, and refrigerate as soon as they ripen.  Ripe pears
should be stored in the refrigerator in a plastic bag up to 3 days. 
They continue to ripen after harvest.  

Table 42. Approximate Storage Life of Pome Fruits in Commercial Storage
(Adapted Hardenburg, et al., 1986, Gast, 1991).

Commodity	Approximate Storage Life With Proper Storage Temperatures

Apple	1 – 12 months

Asian Pear	4 -   6 months

Loquat	1 -   2 months

Pear	2 -   7 months

Quince	2 –   3 months



CHANGES TO EPA DATABASES NEEDED FROM REVISIONS TO THE POME FRUIT CROP
GROUP:

The revisions to the amended Pome Fruit Crop Group 11 will affect the
need to update many Risk Assessment Models, Residue Chemistry
Guidelines, OPP databases, and/or HED Standard Operating Procedures
(SOP).

The affected EPA databases may include the following:

(1) Risk Assessment Models - The terminology in the Food Exposure
Modules of our current Risk assessment Models from DEEM-FCID, Lifeline,
and Cares will need to be updated to reflect new terminology and the new
Crop Group terminology.

	(2) EPA Residue Chemistry Test Guidelines (OPPTS 860.1000, Background),
Table 1 Raw Agricultural and Processed Commodities and Feedstuffs
Derived from Crops and EPA Residue Chemistry Test Guidelines (OPPTS
860.1000, Background), EPA Residue Chemistry Test Guidelines (OPPTS
860.1500, Crop Field Trials), Table 5 Suggested Distribution of Field
Trials by Region for Crops Requiring > 3 trials and Table 6 Regional
Distribution of Crop Production. 

	Any differences between the EPA and NAFTA Crop Production Regions after
the NAFTA Regions are updated will be addressed by the ICCGR Workgroup
or by the EPA HED ChemSAC with attendance by Canada, PMRA and Mexico. 
The EPA Residue Chemistry Test Guidelines (OPPTS 860.1500, Crop Field
Trials) Table 5 Suggested Distribution of Field Trials by Region for
Crops Requiring >3 trials and Table 6 Regional Distribution of Crop
Production will be updated to reflect more recent crop production
information.   There is currently no conflict with Canada.

	(3) Health Effects Division Standard Operating Procedures:  HED SOP
99.3 -  SEQ CHAPTER \h \r 1 – “Translation of Monitoring Data”
issued March 26, 1999.  This policy provides guidance on translating
pesticide monitoring data from one commodity to other similar
commodities.  Most of the monitoring data is from the USDA Pesticide
Data Program (PDP) or the Food and Drug Administration (FDA).  The
policy is based on the crop groupings in the 40 CFR 180.41. 

There is an entry for apple or pear which can be translated to all
members of the Pome Fruit Crop up 11.  USDA PDP peels the apple or
before they analyze them for pesticide residues.  The policy does not
have to be updated at this time, since it will be still be applicable to
the whole crop group.

	(4) HED SOP 99.6 -   SEQ CHAPTER \h \r 1  “Classification of Food
Forms with Respect to Level of Blending” issued August 20, 1999.  This
SOP provides rationale and guidance to HED on revised criteria for
inputting residue values and pesticide usage information into acute
dietary exposure and risk assessments based on commodities.  These
revisions permit the Agency to more fully utilize data generated by the
USDA Pesticide Data Program. 

	Some of the Pome Fruit Crop Group members are included in the HED SOP
99.6.  See Table 43 below.  Other members not in the original SOP will
need to be added to the HED SOP 99.6.  The whole fruits are not blended
and can be uncooked, cooked, baked, boiled, or canned.

(5) HED SOP 2000.1 – “  SEQ CHAPTER \h \r 1 Guidance for Translation
of Field Trial Data from Representative Commodities in the Crop Group
Regulation to Other Commodities in Each Crop Group/Subgroup” issued
September 12, 2000.

There is guidance in the SOP for the current Pome Fruit Crop Group, but
not for the additional proposed commodities, so the current Crop group

COMMODITY DEFINITIONS [(40 CFR ( 180.1(g)]:

	There are currently no commodity definitions for any commodity in the
Pome fruit group.   A commodity definition for crabapple which lists all
the types of crabapples is proposed with this petition and will be
discussed below: 

Proposed 40 CFR ( 180.1(g):

Tolerances and exemptions established for pesticide chemicals in or on
the general category of raw agricultural commodities listed in column A
apply to the corresponding specific raw agricultural commodities listed
in column B. However, a tolerance or exemption for a specific commodity
in column B does not apply to the general category in column A.

      A                                                                 
   B
--------------------------------------------------------------------

Proposed Crabapple Commodity Definition:

Crabapple------------------------------------Crabapple, Malus  spp.
(Rosaceae) (Chinese apple, Chinese crabapple, Chinese flowering apple,
Crabapple, Cutleaf crabapple, Florentine crabapple, Hall crabapple, Iowa
crabapple, Japanese crabapple, Kai do crabapple, Manchurian crabapple,
Paradise apple, Sargent's crabapple, Siberian crabapple, Soulard
crabapple, Southern crabapple, Sweet crabapple, Tea crabapple, Toringa
crabapple, Western Crabapple, Yunnan crabapple, and varieties and/or
hybrids of these.

HED Recommendation on Commodity Definition for Crabapple:

	I recommend ChemSAC reject a Crabapple commodity definition under 40
CFR Part 180.1(g) because these crabapples will be listed in the EPA
Food and Feed Commodity Vocabulary
(http://www.epa.gov/pesticides/foodfeed) as lookup terms and the
preferred term for all of these will be crabapple.  

TOLERANCE EXPRESSION GUIDANCE:

	Until the Federal Register Notice is issued revising the Crop Group
Regulation to establish the amended Pome Fruit Crop Group 11 the
commodities approved for the crop group will have to be listed as
separate commodities at the same tolerance level.  When ChemSAC approves
the Pome fruit crop group 11, the Risk Integration, Minor Use, and
Emergency Response Branch (RIMUERB) of the Registration Division can
immediately implement the amended Crop Group with new tolerance
expressions located in the Section F submissions.  The three tolerance
expression examples will provide an expedited way to establish
tolerances in or on Pome fruit crops, especially for new reduced risk
pesticides, without requiring additional residue data for all the crops
noted.  This will create a practice in the United States which is
already formalized in Canada and promote international harmonization. 
Several tolerance expression examples for guidance purposes for use by
RIMUERB and HED reviewers will be listed below: 

Example 1.  What is the tolerance expression for the amended Pome Fruit
Crop Group 11?

Answer to Example 1:

The tolerance expression for the amended Pome Fruit Crop Group 8 will be
“Fruit, pome, group 11 - 09.”

Example 2.  How will the Crop group appear in the Federal Register for
the proposed crop group regulation [40CFR 180.41(c)]?  This example is
for the Field and External Affairs Division (FEAD) and Registration
Division (RD) use in preparing the new Federal Register Regulation.  The
example follows the same format as the current Crop Grouping Regulation
Federal Register Notice (FR 60, No.95, 5/17/95, 26626-26643).

Answer to Example 2:

“Crop Group 11 - 09: Pome Fruit Crop Group”.

Example 3:  How will I express the tolerances on an interim basis until
the Federal Register Notice is final for the Pome fruit group 11 - 09,
for example at a tolerance level of 1.5 ppm?  This example will be
useful for the Registration Division (RD) and Health Effects Division
(HED) to prepare tolerance tables.  All the new proposed commodities
will have to be listed separately from the crop group tolerance and at
the same level as the crop group.

Answer to Example 3:

EPA FOOD AND FEED COMMODITY VOCABULARY FOR THE POME FRUIT CROP GROUP:

	The following terms for the pome fruit commodities will be incorporated
to the EPA Food and Feed Commodity Database (  HYPERLINK
"http://www.epa.govopp/foodfeed"  http://www.epa.govopp/foodfeed ).  The
Table 45 below is identical to the current Food and Feed Commodity
Vocabulary format.  A search of the lookup terms will link to the EPA
preferred tolerance/commodity term, and the Base crop/animal term is the
specific crop animal terms associated with the preferred term.  Until
the Federal Register Notice for the Crop Group is final, the Crop Group
designation on each term will be listed as no crop group and given the
crop group 99 for the present.

APPENDIX II - Apple Variety Characteristics.

Apples

 

Apples are a round or oval shaped fruit that is harvested from lower
growing trees found in most of the temperate regions of the world.  The
fruit has a thin skin that may range in color from shades of green,
yellow, and red or any combination of these.  The flesh is generally
off-white or cream colored and is very juicy.  They are generally sweet
flavored but may be slightly sour, tart, or even a bit bland depending
on the variety. 

Uses:

Apples can be eaten plain, made into sauce or jelly, or they can be
included in a variety of salads, meat dishes, pies, and other desserts. 
As a dried fruit, apples can be added to a variety of baked goods or in
a fresh form, they can be used to produce juice, vinegar, cider, and
alcoholic beverages, such as hard cider and apple brandy. 

At Their Best:

Some apple varieties are available year round and some are only
available at specific times of the year.  The peak season for apples
will vary with different varieties and locations where they are
harvested.  The best apples are those that are picked fresh from the
tree.  Fresh picked apples will have the best flavor and an extra crisp
texture. 

How to Buy: 

Buy apples that are brightly colored, firm, and free of bruises or
damaged skin.  If the flesh gives under pressure, the apple will be
soft.  The skin on the apple should be taut and show no signs of
shriveling.  Apples are graded according to their size and quality. The
higher the grade, the more expensive the apple. 

Storage:

For best results, place apples in a perforated plastic bag, sprinkle
with water and store in the coldest area of the refrigerator for 2 to 3
weeks.  Apples give ethylene gas that speeds up ripening, so they should
be kept away from other fruits and vegetables to prevent them from
ripening prematurely.  Apples can be stored at room temperature for a
short period of time but should be checked regularly because they will
ripen more rapidly than if stored in the refrigerator.  To store fresh
picked apples for a long period of time, wrap them in paper and place
folded side down in a single layer on a tray.  Store in a cool, dark,
dry place.  The ideal temperature for apple storage is between 32F and
40F.  Dried apples can be stored in a sealed plastic bag in the
refrigerator for an indefinite period of time.

Pear: 

	Pears offer a natural, quick source of energy, due largely to high
amounts of two monosaccharides: fructose and glucose, plus levulose, the
sweetest of known natural sugars, found to a greater extent in fresh
pears than in any other fruit.  Carbohydrates make up 98% of the energy
provided by a pear.  Pears do not have to be peeled because their skin
is tender and an additional source of fiber.  A medium sized pear
provides 4 grams of fiber, or 16% of the recommended daily value.  

Fresh pears offer dietary fiber, much of it in the form of pectin.  A
pear weighing 166 grams provides 2.32 grams of crude fiber, and 4 grams
of dietary fiber, of which 41% is pectin.  Fresh pears also offer
potassium; 210 mg in a medium size pear.  Fresh pears contain Vitamin C.
 One medium size pear provides 7 mg or 10% of the RDA for Vitamin C.
