This drinking water assessment provides Tier II (PRZM-EXAMS) surface
water modeling and Tier 1 (SCI-GROW) groundwater modeling for the
fungicide, mefanoxam ((R)
2-[2,6-dimethylphenyl)-methoxyacetylamino]-propionic acid methyl ester).
 Proposed uses included in the modeling include snap beans, spinach,
caneberries, bushberries (crop group 13-07B), bulb onions (subgroup
3-07A), and green onions (subgroup 3-07B). 

1.	Executive Summary

Tier II estimated drinking water concentrations (EDWCs) were derived
using PRZM/EXAMS (pE5 shell), and Tier 1 ground water concentrations
were derived using SCI-GROW for snap beans, caneberries, bushberries,
spinach, and onions (bulb and green).  Mefenoxam is currently registered
on snap beans, spinach, and on some bushberries (but not the entire
sub-group), caneberries, bulb onions, and green onions.  However, models
and methods used to calculate EDWCs have evolved since these uses were
last assessed.  Therefore, this assessment presents EDWCs that are
calculated using methods that are consistent with current models and
policies.  This assessment did not supercede the previous assessments on
these commodities.  

The previous drinking water assessment (DP 324495) concluded that total
toxic metalaxyl/mefenoxam residue concentrations from Tier II surface
water modeling are not expected to exceed 108.9 μg/L for the 1 in 10
year daily peak concentration, 36.7 μg/L for the 1 in 10 year annual
concentration, and 25.9 μg/L for the 30 year annual average
concentration.  The EDWCs for the crops modeled in this assessment
(Table 1) did not exceed the previous EDWCs for citrus reported in the
previous drinking water assessment (DP 324495, US EPA 2007).  Therefore,
the current EDWCs will not supersede the recommended drinking water
values previously performed for this chemical.

 μg/L.  The current assessment estimated lower groundwater
concentrations than previous assessments.  However, the maximum
metalaxyl concentration in registrant-sponsored ground water monitoring
studies was 3.0 μg/L.  

The Ridomil Gold EC label states not to exceed 3.6 lbs a.i./Acre for
soil applications for caneberries and bushberries.  The Ridomil Gold EC
label should be revised to specify that soil and foliar applications
combined should not to exceed 3.6 lbs a.i./Acre.  This statement is
included in the Ridomil Gold Copper label.

       

Problem Formulation

2.1.	Chemical Identity

Metalaxyl and mefenoxam are systemic phenylamide fungicides with a mode
of action that is specific to controlling oomycetes in fungi.  The mode
of action in fungi is inhibition of RNA synthesis.  The R enantiomer has
more fungicidal activity than the S enantiomer.  Toxicity data, however,
do not suggest that the two enantiomers differ in mode of action or
toxicity in species other than fungi.  SEQ CHAPTER \h \r 1 

The basic physical and chemical properties and structure of metalaxyl
and mefenoxam are presented in Table 2.

2.2.	Proposed Label Changes

The registrant (Syntenta) proposed changes to three labels (Ridomil Gold
SL, Ridomil Gold EC, and Ridomil Gold Copper).  The proposed changes
include the following:

Snap Beans:  Mefenoxam copper is proposed for use on snap beans. 
Mefenoxam is already registered for use on snap beans, and the
application rates, frequency, and method of application for mefenoxam
copper are consistent with the rates already registered for mefenoxam.

Berries:  IR-4 is requesting registration for mefenoxam copper on
caneberries (13-07A) and to expand the blueberry use to all bushberries
(crop group 13-07B).  Mefenoxam is already registered on several berries
including blueberries, cranberries, raspberries, and strawberries.  No
changes are proposed that would increase the single or seasonal
application rates, number of applications, or change the method of
application.  

Spinach:  IR-4 is requesting to reduce the PHI from 21 days to 3 days. 
No other changes are proposed.

Bulb Onions and Green Onions:  Mefenoxam is already registered on
several dry bulb and green onions including garlic, dry bulb onions and
shallots.  IR-4 is requesting to expand these uses to include subgroup
3-07A: great-headed garlic, serpent garlic, lily bulb, Chinese onion
bulb, pearl onion, potato onion bulb.  

Mefenoxam is also currently registered on several green bulb crops
including green eschalots, green onions, green shallots, Japenese
bunching onions, leeks, spring onions, and scallions.  IR-4 is
requesting to expand these uses to include chives, Chinese chives, hosta
elegans, fritillaria, kurrat, lady’s leek, Beltsville bunching onions,
fresh onions, macrostem onion, tree tops onion, Welsh onion, and
shallots (fresh leaves).    

Previous assessments have considered snap beans, berries, spinach, bulb
onions, and green onions.  Given the changes in previous labels for the
commodities noted above , this assessment serves to update the previous
assessments on these commodities based on most revised and updated
labels.  

2.3.	Analysis Plan  

Modeling

PRZM/EXAMS is used to estimate EDWCs for metalaxyl/mefenoxam.  PRZM and
EXAMS are simulation models coupled with the input shell pe5.pl.  The
models generate daily exposures and calculated 1-in-10 year EECs of
metalaxyl and mefenoxam that may occur in surface water bodies adjacent
to application sites receiving metalaxyl and mefenoxam through runoff
and spray drift.  

Evaluation of Degradates

A total toxic residue approach was used in the modeling approach.  The
modeling was conducted for mefanoxam/metalaxyl and the major degradation
product N-(2, 6-dimethylphenyl)-N-(methylacetyl-L-alanine) (CGA-62826)
and N-(3_hydroxy-2, 6-dimethylphenyl)-N-(methoxyacetyl)-L-alanine (CGA
119857).  The degradation product CGA 119857 was only considered in
anaerobic aquatic metabolism half-life determinations.  The modeling
strategy was to address the environmental fate of  mefanoxam/metalaxyl,
CGA-62826, and CGA 119857.  This strategy employs selection of the most
conservative environmental fate parameters for the degradation half-life
and soil:water partitioning coefficient for known mefanoxam/metalaxyl
residues.  

3.	Use Characterization

Application data are summarized in Table 3 and were obtained from the
proposed revised labels submitted in support of the proposed action. 
The modeling considered application rates specified on the revised
labels as summarized in Table 2 and were based on the maximum labeled
application rates for each proposed use.

Surface Water Modeling 

4.1.	Model Inputs

Tier II surface water modeling was conducted using PE5.  The modeling
was conducted for mefanoxam/metalaxyl and the major degradation product
N-(2, 6-dimethylphenyl)-N-(methylacetyl-L-alanine) (CGA-62826) and
N-(3_hydroxy-2, 6-dimethylphenyl)-N-(methoxyacetyl)-L-alanine (CGA
119857).   A discussion of the environmental fate data is included in
Appendix A.  The degradation product CGA 119857 was only considered in
anaerobic aquatic metabolism half-life determinations.  The modeling
strategy was to address the environmental fate of  mefanoxam/metalaxyl,
CGA-62826, and CGA 119857.  This strategy employs selection of the most
conservative environmental fate parameters for the degradation half-life
and soil:water partitioning coefficient for known mefanoxam/metalaxyl
residues.  The modeling considered application rates specified on the
revised labels as summarized in Table 3.  Environmental fate inputs used
for modeling are summarized in Table 4.  The modeling was conducted
using inputs that are equivalent to those used in previous drinking
water assessments (DP 324495, 2007) and those identified in the
registration review problem formulation (DP 368463, 2009).  PRZM/EXAMS
scenarios used in the modeling are listed in Table 5.

6.	Monitoring Data

No NAWQA surface or ground water monitoring data were found for
mefenoxam and metalaxyl.  The registrant (Ciba Geigy) performed a ground
water study on metalaxyl in the mid 1980’s.  The maximum metalaxyl
concentration was 3 µg/L in drinking water wells.  These wells were
located near fields treated with 0.5 to 1.0 lb ai/A.       

7.	Uncertainties, Assumptions, and Limitations

The drinking water assessment employs a bridging strategy for the
environmental fate and transport properties of mefenoxam and metalaxyl. 
There is no consideration of enantioselective degradation or transport
processes for the individual isomers of metalaxyl.  Therefore, the
environmental behavior of individual isomers is assumed to be similar
with no impact on total metalaxyl/mefenoxam residue concentrations in
ground water or surface water at similar application rates.  

Total metalaxyl/mefenoxam residues were considered in modeling.  This
approach assumes degradation products N-(2,
6-dimethylphenyl)-N-(methylacetyl-L-alanine) (CGA-62826) and
N-(3_hydroxy-2, 6-dimethylphenyl)-N-(methoxyacetyl)-L-alanine (CGA
119857) have equivalent toxicity to metalaxyl/mefenoxam.  This approach
is conservative because it assumes the total residues are as persistent
as the most persistent metalaxyl/mefenoxam residue and as mobile as the
most mobile metalaxyl/mefenoxam residue.   

There is uncertainty associated with half-lives for the aerobic aquatic
and anaerobic metabolism because of  low coefficient of determinations
(r2) of  log-transformed first-order regression equations. Use of these
data is expected to yield conservative drinking water concentration
because of the high persistence of metalaxyl/mefenoxam residues in
aquatic environments.  Although the degradation product CGA-62826 has a
lower estimated soil: water partitioning coefficient than parent
metalaxyl/mefenoxam, it was not used in the assessment because it was a
model estimated value.   

7.1.	Label Clarifications 

The Ridomil Gold EC label states not to exceed 3.6 lbs a.i./Acre for
soil applications for caneberries and bushberries.  The label needs to
indicate not to exceed 3.6 lbs a.i./Acre for soil and foliar
applications combined.  This statement is included in the Ridomil Gold
Copper label.

APPENDIX A.  Environmental Fate Summary

This assessment was conducted using registrant submitted data on both
(R,S) 2-[2,6-dimethylphenyl)-methoxyacetylamino]-propionic acid methyl
ester (metalaxyl) and mefenoxam (the enriched R isomer).  Sufficient
acceptable bridging data were submitted to verify that the environmental
fate of mefenoxam is similar to metalaxyl.  Therefore, based on the
limited bridging data submitted (soil photolysis, aerobic soil
metabolism, batch equilibrium, and soil column leaching studies), EFED
concludes that environmental fate studies for metalaxyl and mefenoxam
can be used to predict the environmental fate of mefenoxam.  

Metalaxyl is moderately persistent to persistent in soil and water
environments.  It has a hydrolysis half-life of 200 days in pH 5 and 7
buffer solution and 115 days in pH 9 buffer solution.  Metalaxyl is
photolytically stable (t1/2 = 400 days) in aquatic environments.  Both
metalaxyl and mefenoxam are stable to photodegradation on soil surfaces.

Metalaxyl and mefenoxam are moderately persistent to persistent (t1/2=
36.48 and 179.1 days) in aerobic mineral soils. The major aerobic
degradation product was N-(2,
6-dimethylphenyl)-N-(methylacetyl-L-alanine) (CGA-62826).  Under
anaerobic conditions, metalaxyl is stable to biodegradation. Anaerobic
degradation products  were CGA-62826 and N-(3_hydroxy-2,
6-dimethylphenyl)-N-(methoxyacetyl)-L-alanine (CGA 119857).  

Metalaxyl and mefenoxam are expected to be mobile in soil and aquatic
environments. Freundich adsorption coefficients for mefenoxam range from
0.1 (Koc=20) in sand to 7.6 (Koc=570) in clay.  Metalaxyl and
degradation products were readily leached in soil columns of sand
textured soils with low organic matter.  Both metalaxyl and CGA-62826
were detected in the leachate from aged soil column leaching studies. 
The PESTAN estimated partitioning coefficient (Kd) for CGA-62826 is 0.32
(Malak, S. Memorandum dated  8/12/81).  Metalaxyl has a low
volatilization potential from soil; less than 0.5% of applied metalaxyl
was lost due to volatilization.

Under typical use conditions, metalaxyl is moderately persistent
(t1\2=14 to 56 days) in field dissipation studies.  In aquatic field
studies, metalaxyl had a dissipation half-life of 5 to 20 days in rice
paddy water and 11 to 24 days in soil.  The major degradation product in
field studies was CGA-62826. 

The following additional studies have been submitted and are currently
under review:

MRID 47886102:  Aerobic soil metabolism

MRID 47886103:  Adsorption/desorption
