introduction

This Tier II Drinking Water Assessment for pyraclostrobin is being
submitted in order to determine if the new uses will increase the
residue concentration of pyraclostrobin in surface and ground water, to
quantify these changes, and to characterize the exposure pathways as
influenced by the fate and transport properties of pyraclostrobin.  The
new uses include the following:

Ground and Aerial Application on Oats and Oilseed including canola and
flax (Section 3 request for Headline Fungicide – DP Barcode 334534)

In-Furrow Application on Corn, Soybean, and Sugar-beets (Section 3
request for Headline Fungicide – DP Barcode 340588); Fresh Herbs (crop
group 19)

Ground and Aerial Application on Tropical Fruits (avocado, black sapote,
canistel, mamey, sapote, mango, papaya sapodilla, and star apple) (IR-4
request for Pristine Fungicide – DP Barcode 336190)

Aerial Application on Turf and Ornamentals (Section 3 request for
Insignia Fungicide - DP Barcode 342584).

This assessment was based on the application of the highest seasonal use
rate (proposed or registered) of pyraclostrobin.  The aerial application
on turf and ornamentals contains the highest seasonal application at 0.5
lbs a.i./acre with 6 maximum seasonal applications at 14 day intervals.
The proposed use rate for the aerial application on Turf and Ornamentals
is the same as for the registered use of pyraclostrobin for ground
application on turf (please see the,“Environmental Fate and Ecological
Risk Assessment for the Registration of Pyraclostrobin”, submitted
February 6, 2002.).  However, EFED believes that the aerial use of
pyraclostrobin on turf and ornamentals will possess the upper-bound
concentrations in surface and ground water since spray drift increases
and application efficiency decreases in an aerial application technique.

EXECUTIVE SUMMARY

The subject chemical addressed in this drinking water assessment is
identified by the chemical pyraclostrobin (cabamic acid,
[2-[[[1-(4-chlorophenyl)-1H-pyrazol-3-yl[oxy]methyl]phenyl]methoxy-,meth
yl ester).  The trade name for this compound is Insignia Fungicide.  The
labeled formulation of Insignia Fungicide contains the active ingredient
of pyraclostrobin by 20 percent with other ingredients accounting for
the remaining 80 percent.  

The chemical identification number is 099100.  Figure 1 shows the
chemical composition of pyraclostrobin

Figure 1.  Chemical structure of pyraclostrobin.

 

Measures of exposure for pyraclostrobin in this drinking water
assessment are obtained through modeling efforts only, since
national-scale monitoring data were not identified. The Tier II drinking
water assessment was performed using the Tier II PRZM/EXAMS (PE4V01 perl
shell with PRZM 3.12 beta dated 5/24/01 and EXAMS version 2.98, 7/18/02)
to assess surface water.  Ground water concentrations were estimated
using a Tier I SCI-GROW model (version 2.3, May 16, 2006) since a Tier
II model has not been developed to assess ground water.

Acute effects of pyraclostrobin residues in drinking water are expressed
in annual peak one-in-ten year concentrations, chronic effects in annual
average one-in-ten year concentrations, and cancer effects in 30-year
average concentrations.  The upper-bound Tier II modeling predicts that
the concentrations of pyraclostrobin in surface water are not likely to
exceed 35.6 µg/L for the peak concentration, 2.3 µg/L for the annual
average concentration, and 1.5 µg/L for the 30-year average
concentrations.  The ground water assessment was based on the latest
proposed use rate of pyraclostrobin on turf and ornamentals.  The
SCI-GROW model predicts the acute and chronic concentrations of
pyraclostrobin in shallow ground water to be 0.02 g/L (0.02 ppb).

PROBLEM FORMULATION

Pyraclostrobin is not likely to reach ground water since pyraclostrobin
is tightly bound to soils with Kocs between 6,000 mg/L and 16,000 mg/L
in all soil studies with an arithmetic mean of 9,304 mg/L and median of
7,889 mg/L.  However, EFED believes pyraclostrobin can potentially
contaminate surface water through runoff.  Laboratory and terrestrial
field studies suggest that pyraclostrobin is moderately persistent in
aerobic environments with aerobic aquatic and aerobic soil half-lives
above 80 days but more rapidly decays in an anaerobic soil environment
with half-lives around 3 days.  Pyraclostrobin is also practically
stable with respect to hydrolysis but does undergo rapid photolysis. 
Pyraclostrobin is also subject to spray drift in the proposed foliar
applications.  

This drinking water assessment only addresses the parent compound. 
Major degredates of pyraclostrobin were not found to be of toxicological
concern.  

Figure 2 is the conceptual model showing all exposure pathways from
pyraclostrobin aerial application on Turf and Ornamental effects on
drinking water.  For additional information on pyraclostrobin fate and
transport properties, please refer to the original drinking assessment
for the Florida Turf scenario included with the, “Environmental Fate
and Ecological Risk Assessment for the Registration of
Pyraclostrobin”, submitted February 6, 2002.

pathways for aerial application of pyraclostrobin to Turf and

Analysis

Surface Water

Two Turf scenarios and six Nursery scenarios, as a surrogate to the
Ornamentals crop group, were considered in the surface water assessment
[please see EFED policy memo titled, “Outdoor Nursery Pesticide Root
Zone Model (PRZM) Scenarios for Use in Surface Water Assessments”,
dated July 26, 2007].  A PCA factor of 1.0 was used for all scenarios
consistent with EFED policy (see EFED policy memo, “Golf Course
Adjustment Factors for Simulated Aquatic Exposure Concentrations”,
dated December 7, 2005).  

The PRZM/EXAMS fate parameters and crop-specific inputs and are shown in
Tables 1 and 2 respectively.  The only data gaps in this assessment
includes the lack of aerobic aquatic and anaerobic aquatic metabolism
studies.  Table 1 contains a description of how these data gaps are
addressed in the surface water assessment.  Another potential limitation
in this assessment is that the Nursery scenarios did not address
irrigation.  The upper-bound concentrations should simulate as much
exposure to water from sources such as irrigation channels.  However,
the PRZM model version 3.12 beta does not simulate irrigation.

The estimated concentrations of pyraclostrobin in surface water for each
scenario are shown in Table 3.  The upper-bound estimated pyraclostrobin
residue concentration in surface water appears to result from the New
Jersey Nursery scenario with 6 aerial applications of 0.5 lbs a.i./acre,
14 day intervals.  The PRZM/EXAMS output files are provided in Appendix
A.

ground Water

Ground water concentrations were estimated using a Tier I SCI-GROW model
(version 2.3, May 16, 2006).  The ground water concentrations generated
by SCI-GROW are based on the largest 90-day average recorded during the
sampling period.  Since there is relatively little temporal variation in
ground water concentrations compared to surface water, the model
predicted value can be considered to represent both the acute and
chronic values.

g/L (0.02 ppb).  The SCI-GROW output files for both scenarios are
provided in Appendix B.

The ground water concentrations generated by SCI-GROW are based on the
largest 90-day average recorded during the sampling period.  Since there
is relatively little temporal variation in ground water concentrations
compared to surface water, the concentration of 0.02 µg/L can be
considered as both the acute and chronic values.

Exposure Characterization

This assessment demonstrates that exposure of pyraclostrobin in surface
water is very sensitive to runoff.  The New Jersey Nursery scenario used
in PRZM/EXAMS to diagnose the upper-bound pyraclostrobin residue surface
water concentration reflects a region with high rainfall and high
vulnerability to runoff.

As expected, pyraclostrobin did not show high levels of ground water
concentrations.  The highly immobile property of pyraclostrobin most
probably contributes to this result.  The predicted SCI-GROW
concentration should be conservative typical of a Tier I model.
