NOMINATION
FOR
A
CRITICAL
USE
EXEMPTION
FOR
EGGPLANTS
FROM
THE
UNITED
STATES
OF
AMERICA
1.
Introduction
In
consultation
with
the
co­
chair
of
Methyl
Bromide
Technical
Options
Committee
(
MBTOC),
the
United
States
(
U.
S.)
has
organized
this
version
of
its
Critical
Use
Exemption
nomination
in
a
manner
that
would
enable
a
holistic
review
of
relevant
information
by
each
individual
sector
team
reviewing
the
nomination
for
a
specific
crop
or
use.
As
a
consequence,
this
nomination
for
eggplant,
like
the
nomination
for
all
other
crops
included
in
the
U.
S.
request,
includes
general
background
information
that
the
U.
S.
believes
is
critical
to
enabling
review
of
our
nomination
in
a
manner
that
meets
the
requirements
of
the
Parties'
critical
use
decisions.
With
that
understanding,
the
fully
integrated
U.
S.
nomination
for
eggplants
follows.

2.
Background
In
1997,
the
Parties
to
the
Montreal
Protocol
adjusted
Article
2H
of
the
Protocol,
and
agreed
to
accelerate
the
reduction
in
the
controlled
production
and
consumption
of
methyl
bromide.
This
adjustment
included
a
provision
calling
for
a
phaseout
of
methyl
bromide
by
the
year
2005
"
save
to
the
extent
that
the
Parties
decide
to
permit
the
level
of
production
or
consumption
that
is
necessary
to
satisfy
uses
agreed
by
them
to
be
critical
uses."
At
the
same
time,
the
Parties
adopted
decision
IX/
6,
the
critical
use
exemption
decision,
which
laid
out
the
terms
under
which
critical
use
exemptions
under
Article
2H
would
be
granted.

3.
Criteria
for
Critical
Uses
Under
the
Montreal
Protocol
In
crafting
Decision
IX/
6
outlining
the
criteria
for
a
critical
use
exemption,
the
Parties
recognized
the
significant
differences
between
methyl
bromide
uses
and
uses
of
other
ozone­
depleting
chemicals
previously
given
scrutiny
under
the
Protocol's
distinct
and
separate
Essential
Use
exemption
process.
The
United
States
believes
that
it
is
vitally
important
for
the
MBTOC
to
take
into
account
the
significant
differences
between
the
critical
use
exemption
and
the
essential
use
exemption
in
the
review
of
all
methyl
bromide
critical
use
nominations.

During
the
debate
leading
up
to
the
adoption
of
the
critical
use
exemption
Decision
IX/
6,
an
underlying
theme
voiced
by
many
countries
was
that
the
Parties
wanted
to
phase
out
methyl
bromide,
and
not
agriculture.
This
theme
was
given
life
in
various
provisions
of
the
critical
use
exemption,
and
in
the
differences
in
approach
taken
between
the
critical
use
exemption
and
the
essential
use
exemption.
Those
differences
are
outlined
below.

The
Protocol's
negotiated
criteria
for
the
critical
use
exemptions
for
methyl
bromide
are
much
different
from
the
criteria
negotiated
for
"
essential
uses"
for
other
chemicals.

Under
the
Essential
Use
provisions,
in
order
to
even
be
considered
for
an
exemption,
it
was
necessary
for
each
proposed
use
to
be
"
critical
for
health,
safety
or
the
functioning
of
society."
This
high
threshold
differs
significantly
from
the
criteria
established
for
the
methyl
bromide
Critical
Use
exemption.
Indeed,
for
methyl
bromide,
the
Parties
left
it
solely
to
the
nominating
governments
to
find
that
the
absence
of
methyl
bromide
would
create
a
significant
market
disruption.

For
the
U.
S.
nomination
for
eggplants,
following
detailed
technical
and
economic
review,
the
U.
S.
has
determined
that
some
use
of
methyl
bromide
in
eggplant
production
is
critical
to
ensuring
that
there
is
no
significant
market
disruption.
The
detailed
analysis
of
technical
and
economic
viability
of
the
alternatives
listed
by
MBTOC
for
use
in
growing
eggplants
is
discussed
later
in
this
nomination,
as
is
the
basis
for
the
U.
S.
estimate
of
the
amount
of
methyl
bromide
needed
within
this
sector.

In
the
case
of
methyl
bromide,
the
Parties
recognized
many
agricultural
fumigants
were
inherently
toxic,
and
therefore
there
was
a
strong
desire
not
to
replace
one
environmentally
problematic
chemical
with
another
even
more
damaging.

The
critical
use
exemption
language
explicitly
requires
that
an
alternative
should
not
only
be
technically
and
economically
feasible,
it
must
also
be
acceptable
from
the
standpoint
of
health
and
environment.
This
is
particularly
important
given
the
fact
that
most
chemical
alternatives
to
methyl
bromide
are
toxic
and
pose
some
risk
to
human
health
or
the
environment;
in
some
cases,
a
chemical
alternative
may
pose
risks
even
greater
than
methyl
bromide.

In
the
case
of
methyl
bromide,
the
Parties
recognized
that
evaluating,
commercializing
and
securing
national
approval
of
alternatives
and
substitutes
is
a
lengthy
process.

In
fact,
even
after
an
alternative
is
tested
and
found
to
work
against
some
pests
in
a
controlled
setting,
adequate
testing
in
large­
scale
commercial
operations
in
the
many
regions
of
the
U.
S.
where
a
particular
crop
is
grown
can
take
many
cropping
seasons
before
the
viability
of
the
alternative
can
be
adequately
demonstrated.
In
addition,
the
process
of
securing
national
and
sub­
national
approval
of
the
use
of
alternatives
requires
extensive
analysis
of
environmental
consequences
and
risk
to
human
health.
The
average
time
for
the
national
review
of
scientific
information
in
support
of
a
new
pesticide,
starting
from
the
date
of
submission
to
registration,
is
approximately
38
months.
In
most
cases,
the
company
submitting
the
information
has
spent
approximately
7­
10
years
developing
the
toxicity
data
and
other
environmental
data
necessary
to
support
the
registration
request.

The
Parties
to
the
Protocol
recognized
that
unlike
other
chemicals
controlled
under
the
Montreal
Protocol,
the
use
of
methyl
bromide
and
available
alternatives
could
be
site
specific
and
must
take
into
account
the
particular
needs
of
the
user.

The
Essential
Use
exemption
largely
assumed
that
an
alternative
used
in
one
place
could,
if
approved
by
the
government,
be
used
everywhere.
Parties
clearly
understood
that
this
was
not
the
case
with
methyl
bromide
because
of
the
large
number
of
variables
involved,
such
as
crop
type,
soil
types,
pest
pressure
and
local
climate.
That
is
why
the
methyl
bromide
Critical
Use
exemption
calls
for
an
examination
of
the
feasibility
of
the
alternative
from
the
standpoint
of
the
user,
and
in
the
context
of
the
specific
circumstances
of
the
nomination,
including
use
and
geographic
location.
In
order
to
effectively
implement
this
last,
very
important
provision,
we
believe
it
is
critical
for
MBTOC
reviewers
to
understand
the
unique
nature
of
U.
S.
agriculture,
as
well
as
U.
S.
efforts
to
minimize
the
use
of
methyl
bromide,
to
research
alternatives,
and
to
register
alternatives
for
methyl
bromide.

U.
S.
Consideration/
Preparation
of
the
Critical
Use
Exemption
for
Eggplant
Work
on
the
U.
S.
critical
use
exemption
process
began
in
early
2001.
At
that
time,
the
U.
S.
Environmental
Protection
Agency
(
U.
S.
EPA)
initiated
open
meetings
with
stakeholders
both
to
inform
them
of
the
Protocol
requirements,
and
to
understand
the
issues
being
faced
in
researching
alternatives
to
methyl
bromide.
During
those
meetings,
which
were
attended
by
State
and
association
officials
representing
thousands
of
methyl
bromide
users,
the
provisions
of
the
critical
use
exemption
Decision
IX/
6
were
reviewed
in
detail,
and
questions
were
taken.
The
feedback
from
these
initial
meetings
led
to
efforts
by
the
U.
S.
to
have
the
Protocol
Parties
establish
international
norms
for
the
details
to
be
in
submissions
and
to
facilitate
standardization
for
a
fair
and
adequate
review.
These
efforts
culminated
in
decision
XIII/
11
which
calls
for
specific
information
to
be
presented
in
the
nomination.

Upon
return
from
the
Sri
Lanka
meeting
of
the
Parties,
the
U.
S.
took
a
three
track
approach
to
the
critical
use
process.
First,
we
worked
to
develop
a
national
application
form
that
would
ensure
that
we
had
the
information
necessary
to
answer
all
of
the
questions
posed
in
decision
XIII/
11.
At
the
same
time,
we
initiated
sector­
specific
meetings.
This
included
meetings
with
representatives
of
eggplant
growers
across
the
U.
S.
to
discuss
their
specific
issues,
and
to
enable
them
to
understand
the
newly
detailed
requirements
of
the
critical
use
application.
These
sector
meetings
allowed
us
to
fine
tune
the
application
so
we
could
submit
the
required
information
to
the
MBTOC
in
a
meaningful
fashion.

Finally,
and
concurrent
with
our
preparation
phase,
we
developed
a
plan
to
ensure
a
robust
and
timely
review
of
any
and
all
critical
use
applications
we
might
receive.
This
involved
the
assembly
of
more
than
45
PhDs
and
other
qualified
reviewers
with
expertise
in
both
biological
and
economic
issues.
These
experts
were
divided
into
interdisciplinary
teams
to
enable
primary
and
secondary
reviewers
for
each
application/
crop.
As
a
consequence,
each
nomination
received
by
the
U.
S.
was
reviewed
by
two
separate
teams.
In
addition,
the
review
of
these
interdisciplinary
teams
was
put
to
a
broader
review
of
experts
on
all
other
sector
teams
to
enable
a
third
look
at
the
information,
and
to
ensure
consistency
in
review
between
teams.
The
result
was
a
thorough
evaluation
of
the
merits
of
each
request.
A
substantial
portion
of
requests
did
not
meet
the
criteria
of
decision
IX/
6,
and
a
strong
case
for
those
that
did
meet
the
criteria
has
been
included.

Following
our
technical
review,
discussions
were
held
with
senior
risk
management
personnel
of
the
U.
S.
government
to
go
over
the
recommendations
and
put
together
a
draft
package
for
submission
to
the
parties.
As
a
consequence
of
all
of
this
work,
it
is
safe
to
say
that
each
of
the
sector
specific
nominations
being
submitted
is
the
work
of
well
over
150
experts
both
in
and
outside
of
the
U.
S.
government.
5.
Overview
of
Agricultural
Production
5a.
U.
S.
Agriculture
The
U.
S.
is
fortunate
to
have
a
large
land
expanse,
productive
soils
and
a
variety
of
favorable
agricultural
climates.
These
factors
contribute
to
and
enable
the
U.
S.
to
be
a
uniquely
large
and
productive
agricultural
producer.
Indeed,
the
size
and
scope
of
farming
in
the
U.
S.
is
different
than
in
most
countries.
Specifically,
in
2001,
U.
S.
farm
land
totaled
381
million
hectares,
a
land
area
larger
than
the
size
of
many
entire
countries.
Of
this,
approximately
140
million
hectares
were
devoted
to
cropland,
with
the
rest
devoted
to
pasture,
forest,
and
other
special
uses.
There
were
2.16
million
farms,
with
average
farm
size
across
all
farms
of
176
hectares
(
approximately
10
times
larger
than
average
farm
size
in
the
European
Union).
The
availability
of
land
and
the
fact
that
so
many
U.
S.
regions
are
conducive
to
outdoor
cultivation
of
fruits
and
vegetables,
has
had
an
important
influence
on
the
way
agriculture
has
developed.
Specifically,
these
factors
have
meant
that
greenhouse
production
has
generally
proven
to
be
very
costly
(
in
relative
terms)
and
has
as
a
consequence,
been
limited.

Other
factors
also
affected
the
general
development
of
farming
in
the
U.
S..
While
land
for
farming
is
widely
available,
labor
is
generally
more
expensive
and
less
plentiful.
As
a
result,
the
U.
S.
has
developed
a
system
of
highly
mechanized
farming
practices
that
are
highly
reliant
on
pesticides
such
as
methyl
bromide
and
other
non­
labor
inputs.
The
extent
of
mechanization
and
reliance
on
non­
labor
inputs
can
be
best
demonstrated
by
noting
the
very
low
levels
of
labor
inputs
on
U.
S.
farms:
in
2001,
only
2.05
million
workers
operated
the
2.16
million
U.
S.
farms,
with
help
from
less
than
1
million
hired
workers.

The
U.
S.
agriculture
is
also
unique
in
terms
of
the
broad
range
of
crops
produced.
For
example,
the
fruit
and
vegetable
sector,
the
agricultural
sector
most
reliant
on
methyl
bromide,
is
diverse,
and
includes
production
of
107
separate
fruit
and
vegetable
commodities
or
groups
of
commodities.
With
this
diversity,
however,
has
come
a
large
number
of
pest
problems
that
methyl
bromide
has
proven
uniquely
able
to
address.

Finally,
the
above
factors
have
contributed
to
a
harvest
of
commodities
that
has
enabled
the
U.
S.
to
meet
not
only
its
needs,
but
also
the
needs
of
many
other
countries.
The
U.
S.
produced
88.3
million
metric
tonnes
of
fruits
and
vegetables
in
2001,
up
10
percent
from
1990.
At
the
same
time,
the
land
planted
in
fruits
and
vegetables
has
remained
stable,
and
individual
farm
size
has
increased
as
the
number
of
farms
has
fallen.
The
related
yield
increases
per
land
area
are
almost
exclusively
related
to
non­
labor
inputs,
like
the
adoption
of
new
varieties,
and
the
application
of
new
production
practices,
including
plastic
mulches,
row
covers,
high­
density
planting,
more
effective
pesticide
sprays,
and
drip
irrigation,
as
well
as
increased
irrigation
practices.
Optimization
of
yields
through
these
and
other
scientific
and
mechanized
practices
make
U.
S.
agricultural
output
very
sensitive
to
changes
in
inputs.
Therefore,
as
evidenced
by
the
U.
S.
nomination
for
critical
uses
of
methyl
bromide,
the
phaseout
of
methyl
bromide
can
have
a
very
significant
impact
on
both
the
technical
and
economic
viability
of
production
of
certain
crops
in
certain
areas.
5b.
Eggplant
Production
Production
practices
for
eggplants
are
similar
to
production
of
other
solanaceous
crops
(
e.
g.,
tomato
and
pepper).
The
field
is
plowed
and
disced
to
turn
under
old
crop
residue,
and
then
shaping
the
bed,
fumigating,
and
fertilizing
are
done
prior
to
plastic
application.
A
combination
of
methyl
bromide
+
chloropicrin
(
67/
33)
is
often
used
to
fumigate
beds.
Eggplant
can
be
grown
from
seed
or
from
transplants,
but
is
mostly
started
from
transplants.

Eggplant
is
grown
year
round.
Because
of
the
crop's
extended
harvest
period,
double
cropping
 
or
raising
two
crops
in
one
growing
year
 
is
not
as
common
a
practice
as
it
is
for
pepper
and
tomatoes.
Eggplant
can
be
double
cropped
with
pepper
or
cucumber
following
harvest.
A
spring
crop
of
eggplant
may
follow
a
fall
crop
of
pepper
or
tomato.

Eggplant
does
well
on
well­
drained,
fertile,
sandy­
loam
soils.
Poorly
drained
soils
may
result
in
slow
plant
growth,
reduced
root
systems,
and
low
yields.
Eggplant
requires
a
long,
warm,
frost­
free
growing
season,
usually
of
14
to16
weeks.

Target
Pests

with
Methyl

Eggplant
transplant
beds
and
fields
are
most
seriously
affected
by
weeds,
especially
nutsedges.
The
critical
use
exemption
nomination
is
primarily
based
on
the
lack
of
reliable
alternatives
to
control
nutsedge
species.
Nutsedge
has
a
capacity
to
grow
under
adverse
growing
conditions
and
resist
traditional
and
modern
methods
of
weed
control.

Nematodes
and
fungal
diseases
are
also
of
concern
to
eggplant
producers.
Nematodes
and
fungi
are
expected
to
become
serious
problems
for
eggplant
production
if
methyl
bromide
is
not
available
for
preplant
fumigation.

Yellow
&
Purple
Nutsedge:
Cyperus
spp.
Yellow
nutsedge
(
Cyperus
esculentus
L.)
and
purple
nutsedge
Cyperus
rotundus
L.)
are
perennial
species
of
the
Cyperacea
family
that
are
widely
recognized
for
their
economic
impact
in
agriculture.
Purple
nutsedge
is
considered
the
worst
weed
in
the
world
due
to
its
widespread
distribution
and
the
difficult
control
(
Holm
et
al.
1977).
Nutsedge
is
considered
a
weed
in
at
least
92
countries
and
is
reported
to
infest
at
least
52
different
crops.
Yellow
nutsedge
is
listed
among
the
top
15
worst
weeds
and
is
found
throughout
the
continental
U.
S.
Purple
nutsedge
is
primarily
found
in
the
coastal
areas
of
the
southern
U.
S.
and
along
the
Pacific
coast
in
California
and
Oregon.
A
survey
conducted
in
Georgia
ranked
the
nutsedges
as
the
most
troublesome
weeds
in
the
more
than
30
different
vegetable
crops
grown
there.
(
Webster
et
al.
2001).

Nutsedge
is
propagated
by
tubers
formed
along
underground
rhizomes
and
corms
which
are
underground
stems.
The
parent
tuber
could
be
a
tuber
or
a
corm
from
the
previous
generation.
During
soil
tillage,
the
underground
stems
are
broken
and
new
plants
are
established
from
the
pieces.
A
single
plant
is
capable
of
producing
1,200
new
tubers
within
25
weeks
(
Gilreath
et
al.
1999).
Each
tuber
is
capable
of
sprouting
several
times
(
Thullen
et
al.
1975).
Tuber
populations
between
1,000
and
8,700
per
square
meter
have
been
reported
for
purple
nutsedge
(
Gamini
et
al.
1987).
Nutsedge
is
very
difficult
to
eradicate
once
it
is
established
because
of
dormancy
in
the
tubers
and
their
ability
to
survive
an
array
of
adverse
conditions
for
long
periods
of
time.
Nutsedge
species
are
strong
competitors
with
most
vegetable
crops
for
water
and
nutrients
and
can
reduce
crop
yields
at
low
plant
densities.

Purple
and
yellow
nutsedge
are
serious
problems
in
polyethylene
film
mulch
vegetable
production
systems.
Most
weeds
are
controlled
by
polyethylene
films,
but
nutsedges
are
able
to
penetrate
the
plastic
films
and
actively
compete
with
the
vegetable
crops
causing
reported
yield
losses
of
41
to
89
percent.
(
Patterson,
1998).

There
are
very
few
herbicides
that
control
nutsedge
and
none
are
registered
for
use
on
eggplant.
The
herbicides
that
are
available
for
these
crops
are
generally
older
chemicals
that
are
marginally
effective
against
the
spectrum
of
weeds
that
are
problematic
for
solanaceous
crops.
Approximately
30
to
40
percent
of
the
eggplant
production
areas
covered
by
this
nomination
are
moderately
to
heavily
infested
with
nutsedge.

Root­
knot
Nematode:
Meloidogyne
spp.
Root
damage
caused
by
the
root­
knot
nematode
leads
to
reductions
in
water
and
nutrient
uptake.
Nematodes
induce
galls
(
swelling
in
plant
tissues)
at
root
feeding
sites
which
result
in
symptoms
such
as
stunting,
wilting,
and
chlorosis
(
loss
of
chlorophyll),
and
render
the
plant
more
susceptible
to
secondary
infections.
Pre­
plant
control
of
nematodes
is
important
because
once
root
damage
is
done
and
symptoms
are
evident,
it
is
very
difficult
to
avoid
significant
yield
losses.

Fungal
Diseases:
Phytophthora
blight,
induced
by
Phytophthora
capsici,
causes
seed
rot
and
seedling
blight
in
many
solanaceous
crops
including
eggplant,
pepper,
and
tomato.
In
eggplant,
when
weather
conditions
are
favorable,
this
disease
spreads
rapidly
causing
serious
damage
to
the
crop.
This
is
one
of
the
most
destructive
diseases
and
there
are
few
control
measures.
Southern
stem
blight,
caused
by
Sclerotium
rolfsii,
is
also
a
common
problem
in
eggplant
production.

6b.
Overview
of
Technical
and
Economic
Assessment
of
Alternatives
Eggplant
growers
rely
on
methyl
bromide/
chloropicrin
fumigation
in
the
full­
bed,
plastic
mulch
production
system
to
control
soil­
borne
diseases
and
pests.
Research
on
the
effectiveness
of
non­
chemical
alternatives
to
methyl
bromide
is
preliminary,
particularly
for
high
value,
minor­
use
crops
such
as
eggplant.
Many
of
these
practices
are
under
evaluation,
and
where
possible
have
been
named
as
a
possible
alternative.
However,
these
alternatives
have
not
shown
to
be
stand
alone
replacements
for
methyl
bromide.
Some
of
these
practices
can,
and
are
being
implemented
into
overall
pest
management
strategies.
Methyl
bromide
is
believed
to
be
the
only
treatment
currently
available
that
consistently
provides
reliable
control
of
nutsedge
species
and
the
disease
complex
affecting
eggplant
production.
At
this
time
it
appears
that
use
of
methyl
bromide
will
be
critically
needed
until
an
appropriate
combination
of
fumigants
and
herbicides
is
developed
for
areas
where
high
weed
and
disease
pressure
require
the
broad
spectrum
action
of
methyl
bromide.

Technical
Feasibility
of
Methyl
Bromide
Alternatives
Identified
by
the
MBTOC
Only
not­
in­
kind
(
non­
chemical)
alternatives
to
methyl
bromide
were
identified
by
MBTOC
for
use
on
eggplant.
The
assessment
of
the
technical
feasibility
of
these
alternatives
is
presented
below.

Solarization.
Solarization
is
the
process
of
covering
soil
with
clear
plastic
and
exposing
the
soil
to
direct
sunlight
for
several
weeks.
Solarization
is
a
weather
sensitive
process
that
requires
ideal
soil
moisture
and
sunlight
conditions.
This
treatment
is
most
successful
in
regions
with
continuous
high
temperature
periods
during
summer.
There
are
data
indicating
that
soil
solarization
can
be
an
effective
replacement
for
methyl
bromide
in
the
management
of
several
pests
and
diseases.
Temperatures
of
65
degrees
C
for
30
minutes
will
control
many
soil­
borne
fungi,
nematodes
and
weeds,
with
the
exception
of
Cyperus
species.
Response
of
Cyperus
species
to
solarization
is
sporadic
and
not
well
understood
and
data
show
solarization
to
provide,
at
best,
suppression
of
nutsedge
populations
(
Chase
et
al.
1998;
Egley,
1983).
Field
studies
indicate
that
raising
and
maintaining
soil
temperatures
throughout
the
soil
profile
to
levels
shown
to
control
nutsedge
is
extremely
difficult.
Nutsedges
have
shown
ability
to
emerge
from
deep
in
the
soil
profile
and
to
re­
invade
from
areas
outside
the
solarization
zone,
so
solarization
alone
will
not
be
an
effective
and
dependable
control
method
for
nutsedge.
Solarization
treatments
will
take
fields
out
of
production
since
it
would
be
needed
during
the
spring
and
into
the
summer
months,
which
are
optimal
for
eggplant
production.

Soil
solarization
is
not
a
stand­
alone
replacement
to
pre­
plant
fumigation
with
methyl
bromide
for
control
of
the
wide
range
of
soil­
borne
diseases
and
pests
in
vegetable
crops.
However,
the
available
data
indicate
that
as
part
of
an
IPM
program,
soil
solarization
is
compatible
with
raised­
bed
plastic
mulch
production
systems,
is
cost
effective,
and
can
be
an
effective
tool
for
the
management
of
many
economically
important
pests
and
diseases.
IPM
has
been
adopted
for
management
of
weeds,
diseases,
and
nematodes
on
solanaceous
crops.
However,
problematic
weeds
like
nutsedge
and
soil­
borne
diseases
and
nematodes
are
not
effectively
controlled
by
these
practices
alone.

Solarization/
Fungicides.
Fungicides
are
not
effective
for
control
of
weeds
and
nematodes,
therefore,
their
use
in
combination
with
solarization
is
no
more
efficacious
than
solarization
alone.

Flooding
and
Water
Management.
Flooding
is
not
a
technically
feasible
alternative
to
methyl
bromide
for
several
reasons.
First,
eggplant
requires
well­
drained,
sandy
loam
soil
and
therefore
planting
beds
are
designed
to
provide
good
drainage.
Also,
flooding
does
not
provide
adequate
control
of
the
entire
pest
complex
affecting
eggplant
that
is
controlled
by
methyl
bromide,
especially
nematodes
and
nutsedge.
Cyperus
species
have
shown
tolerance
to
flooding.
Submergence
of
nutsedge
tubers
for
periods
of
8
days
to
4
weeks
showed
no
effect
on
the
sprouting
capabilities
of
the
tubers
(
Horowitz,
1972).
Studies
in
Florida
showed
ineffective
nematode,
disease,
and
nutsedge
control
overall.
(
Allen,
1999)

Additional
factors
prevent
flooding
from
being
a
viable,
cost
effective
alternative
to
methyl
bromide
in
most
areas
in
the
U.
S.
These
include
water
management
regulations,
land
configuration,
the
frequency
and
severity
of
droughts,
and
the
economics
of
developing
and
managing
flood
capabilities.

Grafting/
Resistant
Rootstock/
Plant
Breeding.
Grafting,
resistant
rootstock
and
plant
breeding
are
not
a
stand
alone
replacements
for
methyl
bromide.
Resistant
rootstock
and
plant
breeding
are
primarily
developed
for
nematode
control
and
disease
management.
There
is
no
evidence
that
they
can
be
used
successfully
against
weed
competition.
Grafting
has
not
been
evaluated
for
vegetable
production
due
to
the
high
cost
and
the
large
number
of
plants
that
would
be
needed.
These
alternatives
are
primarily
used
for
nematode
and
disease
management,
but
there
is
no
evidence
that
they
apply
to
competition
from
weeds.

Plant
breeding
is
suited
for
the
management
of
soil­
borne
diseases
as
part
of
an
IPM
program.
This
alternative
is
not
applicable
to
competition
from
weeds.
Breeding
for
resistance
is
a
long­
term
process
and
is
dependent
on
the
availability
of
natural
sources
of
resistance.

Organic
Amendments/
Compost.
The
use
of
compost
as
a
pest
control
tool
is
still
new
and
not
clearly
understood.
Available
data
suggest
that
the
use
of
compost
is
a
viable
alternative
for
suppression
of
some
diseases,
especially
when
used
with
IPM.
However,
results
are
inconsistent
and
therefore
should
not
be
considered
a
stand­
alone
alternative
to
methyl
bromide
for
solanaceous
crop
production.
Also,
organic
amendments
and
compost
do
not
control
nutsedge.

Resistant
Cultivars.
Resistant
cultivars
are
not
technically
feasible
as
a
stand
alone
replacement
for
methyl
bromide
.
Furthermore,
resistant
cultivars
provide
little
control
against
weed
pressures
in
general
and
nutsedge
in
particular.
However,
the
use
of
resistant
cultivars
as
an
alternative
to
methyl
bromide
pre­
plant
fumigation
is
suited
for
the
management
of
soil­
borne
diseases
as
part
of
an
IPM
program.
Breeding
for
resistance
is
a
long­
term
process
and
is
dependent
on
the
availability
of
natural
sources
of
resistance.
To
date,
there
are
no
eggplant
cultivars
with
resistance
to
Phytophthora
and
Meloidogyne,
important
soil­
borne
organisms
that
are
effectively
controlled
by
methyl
bromide.

Substrates
and
Plug
Transplants.
Substrates
(
alternative
growth
media)
and
plug
transplants
(
small
plugs
of
soil
containing
seedlings)
are
not
technically
feasible
as
a
stand
alone
replacements
for
methyl
bromide.
Plug
transplants
are
extensively
used
on
high
value
vegetable
crops
like
eggplants.
However,
even
with
plug
transplants
pre­
fumigation
with
methyl
bromide
is
still
necessary
to
provide
control
of
the
pest
complex.
Also,
plug
transplants
do
not
control
weeds.
Even
when
amended
with
biological
control
organisms,
substrates
and
plug
transplants
provide
limited
disease
resistance
and
control
due
to
the
specific
nature
of
biological
control
microorganisms
and
the
heterogeneous
distribution
of
pathogens
in
soils.
Economic
Feasibility
None
of
the
alternatives
listed
by
MBTOC
and
reviewed
above
were
found
to
be
technically
feasible
for
eggplants
therefore
no
economic
analysis
was
conducted.

Critical
Use
Exemption
Nomination
for
Eggplant
The
critical
use
exemption
nomination
for
the
eggplant
sector
includes
crops
in
the
states
of
Georgia
and
Florida
in
areas
with
heavy
to
moderate
nutsedge
infestation.
The
U.
S.
interdisciplinary
review
team
found
a
critical
need
for
methyl
bromide
for
eggplant
growers
in
Georgia
and
Florida.
The
alternatives
identified
by
the
MBTOC
were,
as
reviewed
in
detail
above,
regarded
by
reviewers
as
technically
infeasible
for
acceptable
management
of
the
major
eggplant
pests,
most
importantly,
yellow
and
purple
nutsedge
and
several
nematode
and
fungal
pathogens.
The
demonstration
above
that
alternatives
are
technically
infeasible
for
controlling
the
major
eggplant
pests
obviates
the
need
to
demonstrate
that
the
alternatives
are
economically
infeasible.

the

Availability
of
Methyl
Bromide
from
Recycled
or
Stockpiled
Sources
In
accordance
with
the
criteria
of
the
critical
use
exemption,
Parties
must
discuss
the
potential
that
the
continued
need
for
methyl
bromide
can
be
met
from
recycled
or
stockpiled
sources.
With
regard
to
recycling
of
methyl
bromide,
it
is
fair
to
say
that
the
U.
S.
concurs
with
earlier
TEAP
conclusions
that
recycling
of
methyl
bromide
used
in
soil
fumigation
is
not
currently
feasible.
The
U.
S.
has
been
investigating
the
level
of
the
existing
stockpile,
and
we
believe
that
whatever
stock
pile
may
now
exist
will
likely
be
fully
depleted
by
2005
when
the
need
for
the
critical
use
exemption
will
start.

9.
Minimizing
Use/
Emissions
of
Methyl
Bromide
in
the
U.
S.

In
accordance
with
the
criteria
of
the
critical
use
exemption,
we
will
now
describe
ways
in
which
we
strive
to
minimize
use
and
emissions
of
methyl
bromide.
While
each
sector
based
nomination
includes
information
on
this
topic,
we
thought
it
would
be
useful
to
provide
some
general
information
that
is
applicable
to
most
methyl
bromide
uses
in
the
country
The
use
of
methyl
bromide
in
the
United
States
is
minimized
in
several
ways.
First,
because
of
its
toxicity,
methyl
bromide
is
regulated
as
a
restricted
use
pesticide
in
the
United
States.
As
a
consequence,
methyl
bromide
can
only
be
used
by
certified
applicators
who
are
trained
at
handling
these
hazardous
pesticides.
In
practice,
this
means
that
methyl
bromide
is
applied
by
a
limited
number
of
very
experienced
applicators
with
the
knowledge
and
expertise
to
minimize
dosage
to
the
lowest
level
possible
to
achieve
the
needed
results.
In
keeping
with
both
local
requirements
to
avoid
"
drift"
of
methyl
bromide
into
inhabited
areas,
as
well
as
to
preserve
methyl
bromide
and
keep
related
emissions
to
the
lowest
level
possible,
methyl
bromide
is
machine
injected
into
soil
to
specific
depths.
In
addition,
as
methyl
bromide
has
become
more
scarce,
users
in
the
United
States
have,
where
possible,
experimented
with
different
mixes
of
methyl
bromide
and
chloropicrin.
Specifically,
in
the
early
1990s,
methyl
bromide
was
typically
sold
and
used
in
methyl
bromide
mixtures
made
up
of
98%
methyl
bromide
and
2%
chloropicrin,
with
the
chloropicrin
being
included
solely
to
give
the
chemical
a
smell
enabling
those
in
the
area
to
be
alerted
if
there
was
a
risk.
However,
with
the
outset
of
very
significant
controls
on
methyl
bromide,
users
have
been
experimenting
with
significant
increases
in
the
level
of
chloropicrin
and
reductions
in
the
level
of
methyl
bromide.
While
these
new
mixtures
have
generally
been
effective
at
controlling
target
pests,
it
must
be
stressed
that
the
long
term
efficacy
of
these
mixtures
is
unknown.
Reduced
methyl
bromide
concentrations
in
mixtures,
more
mechanized
soil
injection
techniques,
and
the
extensive
use
of
tarps
to
cover
land
treated
with
methyl
bromide
has
resulted
in
reduced
emissions
and
an
application
rate
that
we
believe
is
among
the
lowest
in
the
world.

In
terms
of
compliance,
in
general,
the
United
States
has
used
a
combination
of
tight
production
and
import
controls,
and
the
related
market
impacts
to
ensure
compliance
with
the
Protocol
requirements
on
methyl
bromide.
Indeed,
over
the
last
 
years,
the
price
of
methyl
bromide
has
increased
substantially.
As
Chart
1
in
Appendix
D
demonstrates,
the
application
of
these
policies
has
led
to
a
more
rapid
U.
S.
phasedown
in
methyl
bromide
consumption
than
required
under
the
Protocol.
This
accelerated
phasedown
on
the
consumption
side
may
also
have
enabled
methyl
bromide
production
to
be
stockpiled
to
some
extent
to
help
mitigate
the
potentially
significant
impacts
associated
with
the
Protocol's
2003
and
2004
70%
reduction.
We
are
currently
uncertain
as
to
the
exact
quantity
of
existing
stocks
going
into
the
2003
season
that
may
be
stockpiled
in
the
U.
S.
We
currently
believe
that
the
limited
existing
stocks
are
likely
to
be
depleted
during
2003
and
2004.
This
factor
is
reflected
in
our
requests
for
2005
and
beyond.

At
the
same
time
we
have
made
efforts
to
reduce
emissions
and
use
of
methyl
bromide,
we
have
also
made
strong
efforts
to
find
alternatives
to
methyl
bromide.
The
section
that
follows
discusses
those
efforts.

U.
S.
Efforts
to
Find,
Register
and
Commercialize
Alternatives
to
Methyl
Bromide
Over
the
past
ten
years,
the
United
States
has
committed
significant
financial
and
technical
resources
to
the
goal
of
seeking
alternatives
to
methyl
bromide
that
are
technically
and
economically
feasible
to
provide
pest
protection
for
a
wide
variety
of
crops,
soils,
and
pests,
while
also
being
acceptable
in
terms
of
human
health
and
environmental
impacts.
The
U.
S.
pesticide
registration
program
has
established
a
rigorous
process
to
ensure
that
pesticides
registered
for
use
in
the
United
States
do
no
present
an
unreasonable
risk
of
health
or
environmental
harm.
Within
the
program,
we
have
given
the
highest
priority
to
rapidly
reviewing
methyl
bromide
alternatives,
while
maintaining
our
high
domestic
standard
of
environmental
protection.
A
number
of
alternatives
have
already
been
registered
for
use,
and
several
additional
promising
alternatives
are
under
review
at
this
time.
Our
research
efforts
to
find
new
alternatives
to
methyl
bromide
and
move
them
quickly
toward
registration
and
commercialization
have
allowed
us
to
make
great
progress
over
the
last
decade
in
phasing
out
many
uses
of
methyl
bromide.
However,
these
efforts
have
not
provided
effective
alternatives
for
all
crops,
soil
types
and
pest
pressures,
and
we
have
accordingly
submitted
a
critical
use
nomination
to
address
these
limited
additional
needs.

Research
Program
When
the
United
Nations,
in
1992,
identified
methyl
bromide
as
a
chemical
that
contributes
to
the
depletion
of
the
ozone
layer
and
the
Clean
Air
Act
committed
the
U.
S.
to
phase
out
the
use
of
methyl
bromide,
the
U.
S.
Department
of
Agriculture
(
USDA)
initiated
a
research
program
to
find
viable
alternatives.
Finding
alternatives
for
agricultural
uses
is
extremely
complicated
compared
to
replacements
for
other,
industrially
used
ozone­
depleting
substances
because
many
factors
affect
the
efficacy
such
as:
crop
type,
climate,
soil
type,
and
target
pests,
which
change
from
region
to
region
and
among
localities
within
a
region.

Through
2002,
the
USDA
Agricultural
Research
Service
(
ARS)
alone
has
spent
US$
135.5
million
to
implement
an
aggressive
research
program
to
find
alternatives
to
methyl
bromide
(
see
Table
1
below).
Through
the
Cooperative
Research,
Education
and
Extension
Service,
USDA
has
provided
an
additional
$
11.4m
since
1993
to
state
universities
for
alternatives
research
and
outreach.
This
federally
supported
research
is
a
supplement
to
extensive
sector
specific
private
sector
efforts,
and
that
all
of
this
research
is
very
well
considered.
Specifically,
the
phaseout
challenges
brought
together
agricultural
and
forestry
leaders
from
private
industry,
academia,
state
governments,
and
the
federal
government
to
assess
the
problem,
formulate
priorities,
and
implement
research
directed
at
providing
solutions
under
the
USDA's
Methyl
Bromide
Alternatives
program.
The
ARS
within
USDA
has
22
national
programs,
one
of
which
is
the
Methyl
Bromide
Alternatives
program
(
Select
Methyl
Bromide
Alternatives
at
this
web
site:
http://
www.
nps.
ars.
usda.
gov
).
The
resulting
research
program
has
taken
into
account
these
inputs,
as
well
as
the
extensive
private
sector
research
and
trial
demonstrations
of
alternatives
to
methyl
bromide.
While
research
has
been
undertaken
in
all
sectors,
federal
government
efforts
have
been
based
on
the
input
of
experts
as
well
as
the
fact
that
nearly
80
percent
of
preplant
methyl
bromide
soil
fumigation
is
used
in
a
limited
number
of
crops.
Accordingly,
much
of
the
federal
government
pre­
plant
efforts
have
focused
on
strawberries,
tomatoes,
ornamentals,
peppers
and
nursery
crops,
(
forest,
ornamental,
strawberry,
pepper,
tree,
and
vine),
with
special
emphasis
on
tomatoes
in
Florida
and
strawberries
in
California
as
model
crops.

The
USDA/
ARS
strategy
for
evaluating
possible
alternatives
is
to
first
test
the
approaches
in
controlled
experiments
to
determine
efficacy,
then
testing
those
that
are
effective
in
field
plots.
The
impact
of
the
variables
that
affect
efficacy
is
addressed
by
conducting
field
trials
at
multiple
locations
with
different
crops
and
against
various
diseases
and
pests.
Alternatives
that
are
effective
in
field
plots
are
then
tested
in
field
scale
validations,
frequently
by
growers
in
their
own
fields.
University
scientists
are
also
participants
in
this
research.
Research
teams
that
include
ARS
and
university
scientists,
extension
personnel,
and
grower
representatives
meet
periodically
to
evaluate
research
results
and
plan
future
trials.

Research
results
submitted
with
the
CUE
request
packages
(
including
published,
peer­
reviewed
studies
by
(
primarily)
university
researchers,
university
extension
reports,
and
unpublished
studies)
include
trials
conducted
to
assess
the
effectiveness
of
the
most
likely
chemical
and
non­
chemical
alternatives
to
methyl
bromide,
including
some
potential
alternatives
that
are
not
currently
included
in
the
MBTOC
list.

As
demonstrated
by
the
table
above,
U.
S.
efforts
to
research
alternatives
for
methyl
bromide
have
been
substantial,
and
they
have
been
growing
in
size
as
the
phaseout
has
approached.
The
United
States
is
committed
to
sustaining
these
research
efforts
in
the
future
to
continue
to
aggressively
search
for
technically
and
economically
feasible
alternatives
to
methyl
bromide.
We
are
also
committed
to
continuing
to
share
our
research,
and
enable
a
global
sharing
of
experience.
Toward
that
end,
for
the
past
several
years,
key
U.
S.
government
agencies
have
collaborated
with
industry
to
host
an
annual
conference
on
alternatives
to
methyl
bromide.
This
conference,
the
Methyl
Bromide
Alternatives
Outreach
(
MBAO),
has
become
the
premier
forum
for
researchers
and
others
to
discuss
scientific
findings
and
progress
in
this
field.
USDA
funded
studies
related
to
U.
S.
eggplant
production
that
are
currently
on­
going
include
the
following
study:

"
Field
Evaluation
of
Amended
Transplant
Mixes
&
Soil
Solarization
for
Control
of
Soil
Borne
Pathogens"
(
July
1998
­
June
2003).
The
objective
of
the
proposed
research
is
to
evaluate
the
efficacy
of
Plantpro
45,
a
complex
form
of
iodine,
to
control
several
important
pathogens
of
vegetables,
and
to
determine
the
optimum
application
system
for
controlling
soilborne
pathogens
in
currently
used
commercial
production
systems.

In
addition
to
ongoing
USDA
funded
research,
other
eggplant
research
over
the
next
few
years
includes:

Michigan
Eggplant:
Michigan
State
University's
Research
and
Extension
Center
will
test
a
variety
of
alternatives
on
test
plots
owned
by
commercial
growers
in
Michigan
in
2003
and
2004.
They
will
analyze
the
ability
of
these
alternatives
to
control
Verticillium,
Fusarium
and
Phytophthora.
Alternatives
they
will
test
include
Ptyalin
C­
35(
15,32
gal);
Multigard
FFA
(
47,
71
gal/

Multigard
Protect
with
Vapam
HL
(
37,56
gal/
A);
CX­
100
(
applied
as
drip
or
preplant);
Chloropicrin
(
100%);
Iodomethane/
chloropicrin
(
67%/
33%);
and
composted
chicken
manure.

Florida
Eggplant:
Ongoing
research
conducted
by
USDA,
University
of
Florida
Institute
of
Food
and
Agricultural
Sciences
and
the
Florida
Fruit
and
Vegetable
association
will
continue.
In
the
near
term,
additional
attention
will
be
paid
to
Telone/
chloropicrin/
herbicide
combinations.

Based
on
preliminary
results
from
research
conducted
in
this
area
and
largely
in
the
area
of
tomatoes
and
strawberries,
researchers
believe
that
a
mix
of
fumigants
together
with
an
herbicide
treatment
is
the
best
possible
alternative
to
methyl
bromide.
Combinations
of
Telone/
chloropicrin,
and
metam­
sodium/
chloropicrin
are
being
tested
for
disease
and
weed
control.
Future
research
plans
will
test
combinations
of
these
fumigants
with
chemicals
such
as
halosulfuron,
metolachlor,
and
sulfentrazone.
A
program
to
evaluate
host
resistance
to
Phytophthora
root
and
crown
rot
has
been
implemented.
Growers
are
starting
to
deploy
lines
identified
as
having
both
genetic
resistance
and
acceptable
horticultural
qualities.

Research
in
application
technology
(
e.
g.,
injection
methods
and
application
rates)
may
improve
the
uniformity
of
soil
movement
of
chemicals,
such
as
metam­
sodium.
Non­
chemical
alternatives
have
been
incorporated
and
methods
such
as
IPM,
mulching,
solarization,
and
biofumigation
are
being
examined
as
part
of
an
overall
strategy
to
manage
eggplant
production.
Trials
evaluating
compost­
based
systems
as
alternatives
for
chemical­
based
fumigations
are
already
being
conducted.
These
trials
will
continue
and
weed
ratings,
disease
incidence,
and
crop
yield
data
will
be
collected.

While
the
U.
S.
government's
role
to
find
alternatives
is
primarily
in
the
research
arena,
we
know
that
research
is
only
one
step
in
the
process.
As
a
consequence,
we
have
also
invested
significantly
in
efforts
to
register
alternatives,
as
well
as
efforts
to
support
technology
transfer
and
education
activities
with
the
private
sector.

Registration
Program
The
United
States
has
one
of
the
most
rigorous
programs
in
the
world
for
safeguarding
human
health
and
the
environment
from
the
risks
posed
by
pesticides.
While
we
are
proud
of
our
efforts
in
this
regard,
related
safeguards
do
not
come
without
a
cost
in
terms
of
both
money
and
time.
Because
the
registration
process
is
so
rigorous,
it
can
take
a
new
pesticide
several
years
(
3­
5)
to
get
registered
by
EPA.
It
also
takes
a
large
number
of
years
to
perform,
draft
results
and
deliver
the
large
number
of
health
and
safety
studies
that
are
required
for
registration.

The
U.
S.
EPA
regulates
the
use
of
pesticides
under
two
major
federal
statutes:
the
Federal
Insecticide,
Fungicide,
and
Rodenticide
Act
(
FIFRA)
and
the
Federal
Food,
Drug,
and
Cosmetic
Act
(
FFDCA),
both
significantly
amended
by
the
Food
Quality
Protection
Act
of
1996
(
FQPA).
Under
FIFRA,
U.
S.
EPA
registers
pesticides
provided
its
use
does
not
pose
unreasonable
adverse
effects
to
humans
or
the
environment.
Under
FFDCA,
the
U.
S.
EPA
is
responsible
for
setting
tolerances
(
maximum
permissible
residue
levels)
for
any
pesticide
used
on
food
or
animal
feed.
With
the
passage
of
FQPA,
the
U.
S.
EPA
is
required
to
establish
a
single,
health­
based
standard
for
pesticides
used
on
food
crops
and
to
determine
that
establishment
of
a
tolerance
will
result
in
a
"
reasonable
certainty
of
no
harm"
from
aggregate
exposure
to
the
pesticide.

The
process
by
which
U.
S.
EPA
examines
the
ingredients
of
a
pesticide
to
determine
if
they
are
safe
is
called
the
registration
process.
The
U.
S.
EPA
evaluates
the
pesticide
to
ensure
that
it
will
not
have
any
unreasonable
adverse
effects
on
humans,
the
environment,
and
non­
target
species.
Applicants
seeking
pesticide
registration
are
required
to
submit
a
wide
range
of
health
and
ecological
effects
toxicity
data,
environmental
fate,
residue
chemistry
and
worker/
bystander
exposure
data
and
product
chemistry
data.
A
pesticide
cannot
be
legally
used
in
the
United
States
if
it
has
not
been
registered
by
U.
S.
EPA,
unless
it
has
an
exemption
from
regulation
under
FIFRA.

Since
1997,
the
U.
S.
EPA
has
made
the
registration
of
alternatives
to
methyl
bromide
a
priority.
Because
the
U.
S.
EPA
currently
has
more
applications
pending
in
its
review
process
than
the
resources
to
evaluate
them,
U.
S.
EPA
prioritizes
the
applications
in
its
registration
queue.
By
virtue
of
being
a
top
registration
priority,
methyl
bromide
alternatives
enter
the
science
review
process
as
soon
as
U.
S.
EPA
receives
the
application
and
supporting
data
rather
than
waiting
in
turn
for
the
EPA
to
initiate
its
review.
The
average
processing
time
for
a
new
active
ingredient,
from
date
of
submission
to
issuance
of
a
registration
decision,
is
approximately
38
months.
In
most
cases,
the
registrant
(
the
pesticide
applicant)
has
spent
approximately
7­
10
years
developing
the
data
necessary
to
support
registration.
As
one
incentive
for
the
pesticide
industry
to
develop
alternatives
to
methyl
bromide,
the
U.
S.
EPA
has
worked
to
reduce
the
burdens
on
data
generation,
to
the
extent
feasible
while
still
ensuring
that
the
U.
S.
EPA's
registration
decisions
meet
the
Federal
statutory
safety
standards.
Where
appropriate
from
a
scientific
standpoint,
the
U.
S.
EPA
has
refined
the
data
requirements
for
a
given
pesticide
application,
allowing
a
shortening
of
the
research
and
development
process
for
the
methyl
bromide
alternative.
Furthermore,
U.
S.
EPA
scientists
routinely
meet
with
prospective
methyl
bromide
alternative
applicants,
counseling
them
through
the
preregistration
process
to
increase
the
probability
that
the
data
is
done
right
the
first
time
and
rework
delays
are
minimized
The
U.
S.
EPA
has
also
co­
chaired
the
USDA/
EPA
Methyl
Bromide
Alternatives
Work
Group
since
1993
to
help
coordinate
research,
development
and
the
registration
of
viable
alternatives.
The
work
group
conducted
six
workshops
in
Florida
and
California
(
states
with
the
highest
use
of
methyl
bromide)
with
growers
and
researchers
to
identify
potential
alternatives,
critical
issues,
and
grower
needs
covering
the
major
methyl
bromide
dependent
crops
and
post
harvest
uses.

This
coordination
has
resulted
in
key
registration
issues
(
such
as
worker
and
bystander
exposure
through
volatilization,
township
caps
and
groundwater
concerns)
being
directly
addressed
through
USDA's
Agricultural
Research
Service's
$
13.5
million
per
year
research
program
conducted
at
more
than
20
field
evaluation
facilities
across
the
country.
Also
EPA's
participation
in
the
evaluation
of

to
the
USDA's
Cooperative
State
Research,
Education,
and
Extension
Service
methyl
bromide
alternatives
research
program
of
US$
2.5
million
per
year
has
further
ensured
that
critical
registration
issues
are
being
addressed
by
the
research
community.

Since
1997,
EPA
has
registered
the
following
chemical/
use
combinations
as
part
of
its
commitment
to
expedite
the
review
of
methyl
bromide
alternatives:

1999:
Pebulate
to
control
weeds
in
tomatoes
2000:
Phosphine
to

2001:
Telone
applied
through

2002:
Halosulfuron­
methyl
to

EPA
is
currently
reviewing
several
additional
applications
for
registration
as
methyl
bromide
alternatives,
with
several
registration
eligibility
decisions
expected
within
the
next
year,
including:

 
Iodomethane
as
a
pre­
plant
soil
fumigant
for
various
crops
 
Fosthiazate
as
a
pre­
plant
nematocide
for
tomatoes
 
Sulfuryl
fluoride
as
a
post­
harvest
fumigant
for
stored
commodities
 
Trifloxysulfuron
sodium
as
a
pre­

herbicide
for
tomatoes
 
Dazomet
as
a

plant
soil
fumigant
for
strawberries
and
tomatoes
Again,
while
these
activities
appear
promising,
it
must
be
noted
that
issues
related
to
toxicity,
ground
water
contamination,
and
the
release
of
air
pollutants
may
pose
significant
problems
with
respect
to
some
alternatives
that
may
lead
to
use
restrictions
since
many
of
the
growing
regions
are
in
sensitive
areas
such
as
those
in
close
proximity
to
schools
and
homes.
Ongoing
research
on
alternate
fumigants
is
evaluating
ways
to
reduce
emission
under
various
application
regimes
and
examining
whether
commonly
used
agrochemicals,
such
as
fertilizers
and
nitrification
inhibitors,
could
be
used
to
rapidly
degrade
soil
fumigants.
For
example,
if
registration
of
iodomethane
or
another
alternative
occurs
in
the
near
future,
commercial
availability
and
costs
will
be
factors
that
must
be
taken
into
consideration.
It
must
be
emphasized,
however,
that
finding
potential
alternatives,
and
even
registering
those
alternatives
is
not
the
end
of
the
story.
Alternatives
must
be
tested
by
users
and
found
technically
and
economically
feasible
before
widespread
adoption
will
occur.
As
noted
by
TEAP,
a
specific
alternative,
once
available
may
take
two
or
three
cropping
seasons
of
use
before
efficacy
can
be
determined
in
the
specific
circumstance
of
the
user.
In
an
effort
to
speed
adoption
the
United
States
government
has
also
been
involved
in
these
steps
by
promoting
technology
transfer,
experience
transfer,
and
private
sector
training.

11.
Conclusion
and
Policy
Issues
Associated
with
the
Nomination
In
summary,
a
review
of
the
critical
use
exemption
criteria
in
Decision
IX/
6
demonstrates
that
the
Parties
clearly
understood
the
many
issues
that
make
methyl
bromide
distinctly
different
from
the
industrial
chemicals
previously
addressed
by
the
Parties
under
the
essential
use
process.
It
is
now
the
challenge
of
the
MBTOC,
TEAP
and
the
Parties
to
consider
the
national
submission
of
critical
use
nomination
in
the
context
of
that
criteria,
and
the
information
requirements
established
under
Decision
XIII/
11.

In
accordance
with
those
Decisions,
we
believe
that
the
U.
S.
nomination
contained
in
this
document
provides
all
of
the
information
that
has
been
requested
by
the
Parties.
On
the
basis
of
an
exhaustive
review
of
a
large,
multi­
disciplinary
team
of
sector
and
general
agricultural
experts,
we
have
determined
that
the
MBTOC
listed
potential
alternatives
for
the
eggplant
sector
are
not
currently
technically
viable
from
the
standpoint
of
U.
S.
eggplant
growers
covered
by
this
exemption
nomination.
This
is
primarily
due
to
the
technical
infeasibility
of
these
alternatives
to
control
the
major
pests
in
eggplant.

In
addition,
we
have
demonstrated
that
we
have
and
continue
to
expend
significant
efforts
to
find
and
commercialize
alternatives,
and
that
potential
alternatives
to
the
use
of
methyl
bromide
in
eggplant
may
be
on
the
horizon.
That
said,
it
must
be
stressed
that
the
registration
process,
which
is
designed
to
ensure
that
new
pesticides
do
not
pose
an
unacceptable
risk,
is
a
long
and
rigorous
process,
and
the
U.
S.
need
for
methyl
bromide
for
eggplant
will
be
maintained
for
the
period
being
requested
for
an
exemption
in
this
nomination.

In
reviewing
this
nomination,
we
believe
that
it
is
important
for
the
MBTOC,
the
TEAP
and
the
Parties
to
understand
some
of
the
policy
issues
associated
with
our
request.
A
discussion
of
those
follows:

a.
Request
for
Aggregate
Exemption
for
All
Covered
Methyl
Bromide
Uses:
As
mandated
by
Decision
XIII/
11,
the
nomination
information
that
is
being
submitted
with
this
package
includes
information
requested
on
historic
use
and
estimated
need
in
individual
sectors.
That
said,
we
note
our
agreement
with
past
MBTOC
and
TEAP
statements
which
stress
the
dynamic
nature
of
agricultural
markets,
uncertainty
of
specific
production
of
any
one
crop
in
any
specific
year,
the
difficulty
of
projecting
several
years
in
advance
what
pest
pressures
might
prevail
on
a
certain
crop,
and,
the
difficulty
of
estimating
what
a
particular
market
for
a
specific
crop
might
look
like
in
a
future
year.
We
also
concur
with
the
MBTOC's
fear
that
countries
that
have
taken
significant
efforts
to
reduce
methyl
bromide
use
and
emissions
through
dilution
with
chloropicrin
may
be
experiencing
only
short
term
efficacy
in
addressing
pest
problems.
On
the
basis
of
those
factors,
we
urge
the
MBTOC
and
the
TEAP
to
follow
the
precedent
established
under
the
essential
use
exemption
process
for
Metered
Dose
Inhalers
(
MDIs)
in
two
key
areas.

First,
because
of
uncertainties
in
both
markets
and
the
future
need
for
individual
active
moieties
of
drugs,
the
TEAP
has
never
provided
a
tonnage
limit
for
each
of
the
large
number
of
active
moieties
found
in
national
requests
for
a
CFC
essential
use
exemption
for
MDIs,
but
has
instead
recommended
an
aggregate
tonnage
exemption
for
national
use.
This
has
been
done
with
an
understanding
that
the
related
country
will
ensure
that
the
tonnage
approved
for
an
exemption
will
be
used
solely
for
the
group
of
active
moieties/
MDIs
that
have
been
granted
the
exemption.
We
believe
that
the
factors
of
agricultural
uncertainty
surrounding
both
pest
pressures
in
future
year
crops,
and
efficacy
of
reduced
methyl
bromide
application
provide
an
even
stronger
impetus
for
using
a
similar
approach
here.
The
level
of
unpredictability
in
need
leads
to
a
second
area
of
similarity
with
MDIs,
the
essential
need
for
a
review
of
the
level
of
the
request
which
takes
into
account
the
need
for
a
margin
of
safety.

b.
Recognition
of
Uncertainty
in
Allowing
Margin
for
Safety:
With
MDIs,
it
was
essential
to
address
the
possible
change
in
patient
needs
over
time,
and
in
agriculture,
this
is
essential
to
address
the
potential
that
the
year
being
requested
for
could
be
a
particularly
bad
year
in
terms
of
weather
and
pest
pressure.
In
that
regard,
the
TEAP's
Chart
2
in
Appendix
D
demonstrates
the
manner
in
which
this
need
for
a
margin
of
safety
was
addressed
in
the
MDI
area.
Specifically,
Chart
2
in
Appendix
D
tracks
national
CFC
requests
for
MDIs
compared
with
actual
use
of
CFC
for
MDIs
over
a
number
of
years.

Chart
2
in
Appendix
D
demonstrates
several
things.
First,
despite
the
best
efforts
of
many
countries
to
predict
future
conditions,
it
shows
that
due
to
the
acknowledged
uncertainty
of
out­
year
need
for
MDIs,
Parties
had
the
tendency
to
request,
the
TEAP
recommended,
and
the
Parties
approved
national
requests
that
turned
out
to
include
an
appreciable
margin
of
safety.
In
fact,
this
margin
of
safety
was
higher
at
the
beginning
 
about
40%
above
usage
 
and
then
went
down
to
30%
range
after
4
years.
Only
after
5
years
of
experience
did
the
request
come
down
to
about
10%
above
usage.
While
our
experience
with
the
Essential
Use
process
has
aided
the
U.
S.
in
developing
its
Critical
Use
nomination,
we
ask
the
MBTOC,
the
TEAP
and
the
Parties
to
recognize
that
the
complexities
of
agriculture
make
it
difficult
to
match
our
request
exactly
with
expected
usage
when
the
nomination
is
made
two
to
three
years
in
advance
of
the
time
of
actual
use.

Chart
2
in
Appendix
D
also
demonstrates
that,
even
though
MDI
requests
included
a
significant
margin
of
safety,
the
nominations
were
approved
and
the
countries
receiving
the
exemption
for
MDIs
did
not
produce
the
full
amount
authorized
when
there
was
not
a
patient
need.
As
a
result,
there
was
little
or
no
environmental
consequence
of
approving
requests
that
included
a
margin
of
safety,
and
the
practice
can
be
seen
as
being
normalized
over
time.
In
light
of
the
similar
significant
uncertainty
surrounding
agriculture
and
the
out
year
production
of
crops
which
use
methyl
bromide,
we
wish
to
urge
the
MBTOC
and
TEAP
to
take
a
similar,
understanding
approach
for
methyl
bromide
and
uses
found
to
otherwise
meet
the
critical
use
criteria.
We
believe
that
this
too
would
have
no
environmental
consequence,
and
would
be
consistent
with
the
Parties
aim
to
phaseout
methyl
bromide
while
ensuring
that
agriculture
itself
is
not
phased
out.
c.
Duration
of
Nomination:
It
is
important
to
note
that
while
the
request
included
for
the
use
above
appears
to
be
for
a
single
year,
the
entire
U.
S.
request
is
actually
for
two
years
 
2005
and
2006.
This
multi­
year
request
is
consistent
with
the
TEAP
recognition
that
the
calendar
year
does
not,
in
most
cases,
correspond
with
the
cropping
year.
This
request
takes
into
account
the
facts
that
registration
and
acceptance
of
new,
efficacious
alternatives
can
take
a
long
time,
and
that
alternatives
must
be
tested
in
multiple
cropping
cycles
in
different
geographic
locations
to
determine
efficacy
and
consistency
before
they
can
be
considered
to
be
widely
available
for
use.
Finally,
the
request
for
multiple
years
is
consistent
with
the
expectation
of
the
Parties
and
the
TEAP
as
evidenced
in
the
Parties
and
MBTOC
request
for
information
on
the
duration
of
the
requested
exemption.
As
noted
in
the
Executive
Summary
of
the
overall
U.
S.
request,
we
are
requesting
that
the
exemption
be
granted
in
a
lump
sum
of
9,920,965
kilograms
for
2005
and
9,445,360
kilograms
for
2006.
While
it
is
our
hope
that
the
registration
and
demonstration
of
new,
cost
effective
alternatives
will
result
in
even
speedier
reductions
on
later
years,
the
decrease
in
our
request
for
2006
is
a
demonstration
of
our
commitment
to
work
toward
further
reductions
in
our
consumption
of
methyl
bromide
for
critical
uses.
At
this
time,
however,
we
have
not
believed
it
possible
to
provide
a
realistic
assessment
of
exactly
which
uses
would
be
reduced
to
account
for
the
overall
decrease.
