;L     SCIENCE FINDINGS

       Fluoxastrobin is a broad-spectrum strobilurin fungicide that has been proposed for use on
peanuts, tuberous (potato) and corm vegetables, leaf petiole vegetables, fruiting vegetables, turf,
and for seed treatment of potato, peanut and turf. The HEC 480 SC Fungicide label-suggests
rotating, alternating, or tank-mixing with products having different modes of action and/or
limiting the total number of applications per season in an effort to delay the development of
resistance in plant pathogen populations.

PHYSICAL AND CHEMICAL PROPERTIES

       Technical fluoxastrobin is a white, crystalline solid.  It is essentially insoluble in water
(solubility of 0.0023 g/L in water at pH 7), but is highly soluble in dichloromethane,
polyethylene glycol 400, acetone, ethyl acetate, acetonitrile, and dimethylsulfoxide. Technical
fluoxastrobin has a melting point of 103-105° C, and a log Pow of 2.85 at 20° C. It does not
dissociate in water at pH 4 to 9 and has a vapor pressure of 5.63xlO"10 Pa at 20° C.

HAZARD CHARACTERIZATION

Acute Toxicity

       Fluoxastrobin technical has a low order of acute toxicity based on its classification in
Toxicity Category III (LD50 > 2000 mg/kg) via the oral and dermal  routes, and Toxicity Category
IV by the inhalation route of exposure.  Fluoxastrobin is a moderate eye irritant (Toxicity
Category III), but is neither a dermal irritant nor a sensitizer.

       The end use product HEC 480 SC Fungicide is an emulsifiable concentrate. This product
has a very low order of acute toxicity based on its classification in Acute Toxicity Category IV
for all exposure routes. This product is presently classified as a dermal sensitizer but not due to
the active ingredient.

Subchronic and Chronic Toxicity

       Fluoxastrobin has a mild or low toxicity following repeated administration in the rat and
mouse but higher toxicity in the dog.  In both the 90-day and one-year oral feeding dog studies,
there was liver toxicity in the form of cholestasis as  evidenced by hepatocytomegaly and
cytoplasmic granular changes associated with increased liver weight and increased serum liver
alkaline phospatase (ALP).  The no observed adverse effect level (NOAEL) of 1.5 mg/kg/day in
the one year dog study was used for setting the chronic reference Dose (RfD).

       In the 90-day  oral toxicity study in rats, the urinary system in males was a target organ as
evidenced by increased kidney weight and histopathology findings in kidneys, urinary bladder,
and urethra including the presence of calculi in the urethra and kidneys. The adrenal glands seem

-------
to be another target organ in males of the 90-day rat study where vacuolation was seen in the
zona fasciculate of the adrenal cortex. The adrenal changes are not likely to be endocrine related
effects.

In the 90-day oral toxicity in mice, increases in liver and kidney weights were observed.

Developmental and Reproductive Toxicity

       In the rat and rabbit developmental toxicity studies and the two-generation reproduction
rat study, there was no increased susceptibility to prenatal or postnatal exposure to fluoxastrobin
and no effects on reproduction.

Neurotoxicity

       Fluoxastrobin is not acutely neurotoxic in rats up to a single high dose of 2000
mg/kg/day or by repeated dietary feeding in the  rat subchronic neurotoxicity screening study
where the top dose was nearly half the limit dose of 1000 mg/kg/day.  There were no treatment-
related neurotoxicity findings in dogs.

Immune System Toxicity

       Fluoxastrobin is not immunotoxic based on repeated dosing studies in rats and mice.

Carcinogenicity

       The carcinogenic potential of fluoxastrobin was adequately tested in rats and mice of
both sexes. There was no evidence of carcinogenicity in rats or mice.

Mutagenicity

       Fluoxastrobin and its major metabolites gave negative results in a battery of genotoxicity
tests.

DOSE RESPONSE ASSESSMENT AND FOOD QUALITY PROTECTION ACT (FOPA)
CONSIDERATION

Dose Response Assessment

       Based on submitted data, the Agency determination of the acute and chronic Reference
Doses (RfDs), toxicological endpoint selections, and appropriate margins of exposure (MOEs)
for use as appropriate in occupational/residential exposure risk assessments, is summarized
below:

-------
Acute Dietary Reference Dose (aRfD): No acute toxicity endpoint was identified for
either females age 13-49 years or the general population. There was no endpoint noted in
the database from a single dose exposure that could be used for risk assessment. This
included the acute neurotoxicity (tested to the limit dose) and developmental studies as
well as the other short- and long-term studies.

Chronic Dietary Reference Dose (cRfD): Fluoxastrobin has a mild or low toxicity
following repeated administration in all tested species other than the dog. The dog
appears to be the most sensitive species.  For all populations, the dose and endpoint for
establishing a cRfD is a LOAEL of 7.7 mg/kg/day (NOAEL for females) from the one
year toxicity study in dogs. The NOAEL is 1.5 mg/kg/day (NOAEL for females) based
on body weight reductions and liver toxicity (cholestasis) in both sexes. An uncertainty
factor (UF) of 100 was selected (lOx inter-species extrapolation, lOx intra-species
variability)  and the cRfD is 0.015mg/kg/day.

Incidental Oral Short-Term (1-30 Days) Exposure: The dose and endpoint chosen is
the NOAEL of 3.0 mg/kg/day from the 90-day oral toxicity study in the dog. The UF is
100.

Incidental Oral Intermediate-Term (1-6 Months) Exposure: The dose and endpoint
chosen is the NOAEL of 3.0 mg/kg/day based on 90 day-oral toxicity studies in the dog.
TheUFis 100.

Dermal Absorption Factor: A dermal absorption factor of 2.3% was chosen by the
Agency based on a study which was conducted using five male rhesus monkeys.

Dermal Short-Term (1-30 Days) Exposure: There was no systemic or localized hazard
noted in a 28-day dermal toxicity study in the rat and there are  no developmental or
reproductive toxicity concerns, therefore this risk assessment is not necessary.

Dermal Intermediate-Term (1-6 Months) Exposure: The dose and endpoint chosen is
the NOAEL of 3.0 mg/kg/day based on 90-day oral toxicity tests in the dog..

Dermal Long-Term (>6 Months) Exposure: The dose and endpoint chosen is the
NOAEL of 1.5 mg/kg/day based on a  chronic oral toxicity study in the dog.

Inhalation  Short- (1-30 Days) & Intermediate-Term (1-6 Months) Exposure: The
dose and endpoint chosen is the NOAEL of 3.0 mg/kg/day based on 90-day oral toxicity
studies in the dog.

Inhalation  Long-Term (>6 Months) Exposure:  The dose and endpoint chosen is the
NOAEL of 1.5 mg/kg/day based on a  chronic oral toxicity study in the dog.

-------
       Margins of Exposure: Table 1 presents a summary of target Margins of Exposure
       (MOEs) for risk assessment. MOE's less than 100 are considered to be of concern.

FQPA Decisions

Special FQPA Safety Factor

       The toxicology database for fluoxastrobin is adequate to support the reduction of the
special FQPA SF to IX because there are no/low concerns and no residual uncertainties with
regard to pre- and/or postnatal toxicity.

Endocrine disruption

       In the available toxicity studies on fluoxastrobin, there was no estrogen, androgen, and/or
thyroid mediated toxicity.  The findings of increased incidences of uterine adenocarcinoma and
thyroid follicular cell adenoma in the rat chronic toxicity/carcinogenicity study were determined
to be unrelated to treatment.  These observations, which were found within random occurrence in
this strain of rats, are not treatment-related and, henceforth, are not indicative of possible
endocrine disruption. When additional appropriate screening and/or testing protocols being
considered under the Agency's EDSP have been developed, fluoxastrobin may be subjected to
further screening and/or testing to better characterize  effects related to endocrine disruption.

HUMAN HEALTH EXPOSURE AND RISK ASSESSMENT

-------
Residue Profile
       Following multiple foliar applications, detectable combined residues of fluoxastrobin
and its Z-isomer are likely to be present in/on tomato, pepper, and trimmed celery at up to 0.6
ppm.  Residues on peanut hay are likely to be much higher (up to 17 ppm), but non-detectable
(<0.01 ppm) in peanut nutmeats and tuberous and corm vegetables. The residue of concern in/on
primary and rotated plant commodities for tolerance setting and risk assessment purposes are
fluoxastrobin and its Z-isomer.  The residues of concern for livestock for tolerance setting and
risk assessment purposes are fluoxastrobin, its Z-isomer, and the phenoxy-hydroxypyrimidine
metabolite. Based upon the results of the poultry metabolism study, EPA concludes that the
proposed uses do not require tolerances for poultry commodities because there is no reasonable
expectation of finite residues in poultry commodities.

       A drinking water assessment for fluoxastrobin was conducted for fluoxastrobin used
according to proposed labeling for HEC 480 SC Fungicide. The results from the use of these

Residential Exposure Estimates

       Proposed use of fluoxastrobin on turf may result in individuals of varying ages
potentially being exposed from activities in areas that have been treated. Potential routes of
exposure include dermal (adults and children) and incidental oral ingestion (toddlers only).
While it is assumed that most residential use will result in short-term (1 to 30 days)
postapplication exposures, it is also believed that intermediate-term exposures (> 30 days to 180
days) are possible, albeit unlikely. Recreational exposures to turf are expected to be similar to,
or in many cases less than those evaluated for Home Uses, so they were not evaluated separately.
The resulting risks for children, which are lower than those for adults, are presented in Table 4.

       The total MOE for children's combined risk from activities on treated turf is larger than
100, and therefore does not exceed EPA's level of concern.
Other (Spray Drift, etc.)
       Fluoxastrobin can be directly applied to residential turf by non-resident professional
applicators, and does not result in exposures of concern. Based on this assessment, EPA believes
that it is unlikely there is a higher potential for risk of exposure to spray drift from residential
uses versus agricultural uses of this chemical.

-------
Aggregate Risk

       As per FQPA, 1996, when there are potential residential exposures to the pesticide,
aggregate risk assessment must consider exposures from three major sources: oral, dermal and
inhalation exposures. The toxicity endpoints selected for these routes of exposure may be
aggregated as follows:

       For short-term aggregate exposure assessment, incidental oral and inhalation cannot be
       combined due to differences in the endpoint, i.e. neurotoxicity for incidental oral and
       decreases in body weight for inhalation.  No quantification of dermal risk is required.

       For intermediate-term aggregate exposure, oral and dermal and inhalation endpoints can
       be aggregated because of the use of a common endpoint (decreased body weight gain).

       For long-term aggregate exposure, incidental oral and dermal and inhalation endpoints
       can be aggregated because of the use of oral equivalents and a common endpoint
       (decreased thymus weight).

Short and Intermediate-Term Aggregate Risk

       There is potential short- and intermediate-term exposure to fluoxastrobin via the dietary
(which is considered background exposure) and residential (which is considered primary)
pathways. For adults, these pathways lead to exposure via the oral (background) and dermal
(primary) routes. For children these pathways lead to exposure via the oral (background), and
incidental oral and dermal (primary) routes.

Chronic Aggregate Risk Assessment (Food and Drinking Water)

       There is potential chronic exposure to fluoxastrobin via food and drinking water, i.e., the
dietary route. DWLOCs were calculated to determine if aggregate chronic risks are of concern.
The chronic DWLOCs are much greater than the EDWCs; thus, chronic aggregate risks do not
trigger the Agency's  concern.

Cumulative Risk Characterization/Assessment

       EPA has not made a common mechanism of toxicity finding as to fluoxastrobin and any
other substances, and fluoxastrobin does not appear to produce a toxic metabolite produced by
other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that
fluoxastrobin has a common mechanism of toxicity with other substances.

Occupational Exposure/Risk Pathway

       There is potential for occupational handler exposure from the application of fluoxastrobin
on both food and non-food use sites resulting from handling fluoxastrobin products (i.e.,

-------
mixer/loaders and applicators); and there is potential for occupational postapplication exposure
resulting from entering areas previously treated with fluoxastrobin.

       Occupational handlers may be exposed by the dermal route and by the inhalation route
during mixing, loading and application  of fluoxastrobin for both short-  and intermediate-term
durations.

       Only one occupational handler scenario related to seed treatment triggered the agency's
concern. Although the combined MOE  (accounting for both dermal and inhalation exposures)
was below 100, the risk estimate is probably not a real risk concern, for the following reasons:
First, the inhalation component of the risk estimate is driving the low MOE, but this component
was calculated using surrogate data from a dust formulation, and fluoxastrobin is a liquid
formulation, which is less prone to be available in the air (if the fluoxastrobin liquid formulation
is aerosolized, then inhalation exposure could be a concern). Additionally, at the chemical level,
fluoxastrobin is not volatile. Also, the dermal  component of the combined MOE is also a
conservative screening level estimate, because it is an intermediate-term estimate, while actual
exposures are short- and intermediate term in duration (a short term dermal endpoint was not
identified).

Short-/Intermediate-Term Postapplication Risk

       Fluoxastrobin has been proposed for both food (i.e., agricultural) and non-food (i.e.,
residential and commercial) use sites. Agricultural postapplication exposures may occur from a
variety of activities following treatment of peanut, leafy vegetable, fruiting vegetable and potato
and tuber vegetable crops. Use sites with potential residential exposures include golf course turf,
turf farms, recreational turf, and residential lawns.

       The MOEs for all occupational/agricultural postapplication activities exceed 100 on the
day of treatment (i.e., day 0) for all reentry tasks for all proposed use sites, and therefore, do not
exceed the Agency's level of concern.

       The reentry interval (REI) of 12 hours appearing on the proposed fluoxastrobin end use
label is acceptable.

Non-occupational Off-Target Exposure

       Based on this assessment and required label restrictions, the Agency believes it is
unlikely that there is  higher potential  for risk of exposure to spray drift  from residential uses of
this chemical than have been assessed for direct agricultural applications.
5.     ENVIRONMENTAL EXPOSURE AND RISK

                                            10

-------
       The slow biodegradation, compounded with low mobility in soils, low water solubility,
and a relatively low octanol/water partition coefficient suggest that fluoxastrobin may have
limited potential  for runoff and low bioaccumulation. The low vapor pressure and low Henry's
Law Constant suggest that this compound is not expected to volatilize from water or soils in
natural environments.  Fluoxastrobin's soil degradates, HEC 5725-E-des-chlorophenyl (HEC
7155) and HEC5725-carboxylic acid (HEC 7180) have higher mobilities than does
fluoxastrobin.
Environmental Fate Characteristics

       Biodegradation under aerobic conditions could take several months to several years,
depending on the soil texture (half life of 29.4 days in sandy loam to 393 days in loamy sand;
average half-life  of 141 days).

       Fluoxastrobin is expected to have low to medium mobility, as it absorbs strongly to all
tested soils. Fluoxastrobin could persist for several months in non-sand soils to several years in
sandy type soils.  Under field conditions of intended use areas in the US, fluoxastrobin was
shown to persist for over a year but did not seem to leach underground.

       Fluoxastrobin (E + Z isomers, 98:2 isomer ratio) is stable toward abiotic hydrolysis in
sterile buffered solutions at pH 4, 7, and 9 at 50° C.  In contrast, direct aqueous photodegradation
under laboratory  conditions is rapid, with an average half life of 4.1 days (24 hour irradiation) and
formation of HEC5725-oxazepine. This laboratory half-life corresponds to a predicted
environmental half life of 20.1 summer sunlight in Phoenix, Arizona (33° N) and 28.3 days in
Edmondton, Alberta, Canada (53°N).  However, aqueous photolysis with the formation of
HEC5725-oxazepine was not observed under field conditions since photodegradation in turbid
and/or deeper waters may be limited by the attenuation of sunlight due to unfavorable conditions.
Photodegradation on soils is much slower at a predicted environmental rate of 146 days.

Ecological Effects and Risk

Terrestrial Animals

Toxicity

       Based on submitted acute and reproduction data using bobwhite quail, rats, honeybees,
and earthworms,  fluoxastrobin is classified as practically non-toxic to terrestrial  animals.

Exposure

       The calculated mean residue EECs ranged up to 170 ppm for short turf grass.

       Birds  and mammals  in the field may be exposed to seed treated with pesticides by
ingesting material directly with the diet. They also may be exposed by other routes, such as

                                           11

-------
incidental ingestion of contaminated soil, dermal contact with treated seed surfaces and soil
during activities in the treated areas, preening activities, and ingestion of drinking water
contaminated with pesticide.

Risk

Birds

       Fluoxastrobin is classified as practically non-toxic to birds on an acute exposure basis.
All calculated avian acute and chronic RQs using bobwhite quail were less than LOCs, with acute
values ranging from <0.002 to <0.06 and chronic values ranging from 0.02 to 0.68 respectively.

Mammals

       All calculated mammalian acute RQs were less than LOCs with the exception of small
mammal (15-g) consumption of predicted maximum residue levels of fluoxastrobin on short grass
following the maximum application rate for turf (i.e., 4 times per year). The RQ value for a 15-g
mammal, based on consumption of short grass at the maximum residue level (314 mg/kg diet)
following the maximum application rate for turf,  is <0.15. A definitive LD50 was not established
for laboratory rats because the available acute toxicity data show no mortality  at the highest doses
tested. The RQ value of <0.15 is based on an acute mammalian LD50 value of >2000 mg/kg.

       Although the acute endangered LOG is exceeded for the 15-g mammal (based on
maximum short grass residue and maximum application rates for turf), there is uncertainty
associated with the RQ value because it based on the highest dose tested where no mortality was
observed. In addition, RQ values for the 15-g mammal do not  exceed the acute endangered
species LOG of 0.1, based on consumption of mean residue levels of short grass  (RQ <0.08) or
reduction in the application rate of turf from 4 to  2 times per year (RQ < 0.10). Furthermore, use
of the >5000 mg/kg LD50 value for the  TEP (40.5% fluoxastrobin) results in RQ  values well
below acute LOCs.  Therefore, acute mammalian risks associated with exposure to fluoxastrobin
on short grass are unlikely.

       All calculated mammalian chronic RQs were less than LOCs, with chronic values ranging
from 0.01 to 0.31.  Mammalian RQ values based on exposure to treated seeds were also well
below levels of concern.

Non-Target Insects

       An appropriate label statement is required to protect foraging honeybees  if the LD50 is <
11 jig/bee. Based on the acute contact  toxicity study to honeybees, the LD50 for  fluoxastrobin is
>200  jig/bee. Therefore, the label statement is not required.  Fluoxastrobin is classified as
practically non-toxic to honeybees.

Earthworms

                                           12

-------
       Earthworm exposures to fluoxastrobin and its degradates in soil are not expected to be an
exposure route of concern because acute and subchronic LC50 toxicity values for both the parent
and fluoxastrobin degradates are relatively high at >1000 mg/kg, and no significant mortality
and/or sublethal effects were observed in any of the treatment groups.

Terrestrial Plants

Toxicity

       Fluoxastrobin is not likely to cause adverse effects to non-target terrestrial plants, based
on data from emergence and vegetative vigor tests on 10 different species of plants, after
application of the formulated product at a single concentration of 0.54 Ibs ai/A. This
concentration is equal to the maximum application rate for fluoxastrobin.  In both the seedling
emergence and vegetative vigor tests, no monocot or dicot species were significantly affected by
the treatment, and no reductions exceeded 25%.  The respective NOAEC and EC25 values were
0.54 and >0.54 Ibs ai/A for all test species.

Exposure

       At the maximum label application rate for fluoxastrobin, no non-target monocot or dicot
species were significantly affected by the treatment, and no growth reductions exceeded 25%. If
use directions for approved uses are followed, non-target exposures are expected to be minimal.

Risk

       All acute non-endangered and endangered RQs for non-target terrestrial and semi-aquatic
plants are less than LOCs, with acute non-endangered values ranging from <0.04 to <0.45 and
acute endangered species values ranging from 0.04 to 0.45, respectively.

Aquatic Animals

Toxicity

       On an acute basis, Fluoxastrobin  is moderately toxic to estuarine/marine fish; highly toxic
to freshwater fish and invertebrates; and  very highly toxic to estuarine/marine invertebrates.
Chronic LOCs are also exceeded for estuarine/marine invertebrates and mollusks.  Chronic
effects for estuarine/marine invertebrates include reduced survival and reductions in wet weight
of surviving adults following a 28-day exposure duration. No data were available to assess the
chronic toxicity of fluoxastrobin to estuarine/marine mollusks. Therefore, the NOAEC value was
estimated based on the acute-to-chronic ratio for mysid shrimp.
                                            13

-------
Exposure

       Surface water concentrations ranging from 4.3 to 32.9 ppb resulting from fluoxastrobin
application to selected crops were predicted with the Tier II models PRZM-EXAMS. Peak EECs
were then compared to acute toxicity endpoints to derive acute RQs. The 60-day EECs were
compared to chronic toxicity endpoints (NOAEC values) to derive chronic RQs for freshwater
and estuarine/marine fish, and 21-day EECs were compared to chronic toxicity endpoints for
freshwater and estuarine/marine invertebrates.

Risk

       The ecological risks to fish and invertebrates are considered conservative estimates
because they are based on worst case exposure and use scenarios. Nonetheless, because of the
potential for exposure and possible adverse effects of fluoxastrobin to endangered and non-
endangered fish and invertebrates, the registrant is required to provide information on the
proximity of Federally listed freshwater fish and invertebrates to the fluoxastrobin use sites. This
requirement may be satisfied in one of three ways: 1) having membership in the FIFRA
Endangered Species Task Force (Pesticide Registration [PR] Notice 2000-2); 2) citing FIFRA
Endangered Species Task Force data; or 3) independently producing these data, provided the
information is of sufficient quality to meet FIFRA requirements.  The information will be used by
the OPP Endangered Species Protection Program to develop recommendations to avoid and
mitigate adverse effects to listed species.

       Risk quotients (RQs) were calculated from the ratio of estimated environmental
concentrations (EECs) to ecotoxicity values.  Peak EECs were compared to acute ecotoxicity
endpoints to derive acute RQs for aquatic animals. Chronic RQs were derived by comparing 60-
day EECs to NOAEC values (chronic toxicity endpoints) for freshwater organisms and 21-day
EECs to NOAEC values for estuarine/marine organisms.  The RQs are then compared to the
Agency's levels of concern (LOCs) to indicate when a pesticide's use as directed on the label has
the potential to cause adverse effects on non-target organisms. These LOCs are part of the
Agency's interpretive policy and are used to analyze potential risk to non-target organisms and
the need to consider regulatory  action.

       Acute and chronic RQs for freshwater  organisms are summarized in Table 15. Estimates
of benthic sediment exposure to pesticides can be provided by PRZM/EXAMS but this
assessment was not performed for fluoxastrobin because toxicity data related to sediment
exposure are not available. Therefore, acute (10-day) and chronic (28-day) sediment toxicity
testing, as described in the OPPTS 850.1735 and 850.1740 protocols, are required in order to
reduce uncertainties and evaluate risks to freshwater and estuarine/marine sediment-dwelling
organisms.

       For the current application rates modeled on major crops where fluoxastrobin is applied,
acute endangered species LOCs are exceeded for freshwater fish (in Maine potatoes, Florida
tomatoes, peppers, peanuts, and turf at the maximum application rate of 4x/year) and freshwater
invertebrates (in all crops with the exception of ground application of potatoes in Idaho).  Acute
RQ values range from 0.01 to 0.08 for freshwater fish, and from 0.04 to 0.27 for freshwater
invertebrates. Chronic RQs for freshwater fish (0.07 to 0.55) and invertebrates (0.02 to 0.18) are
less than chronic LOCs.

       The acute and chronic RQs for estuarine and marine animals are summarized in Table 16.

f exceeds acute endangered species level of concern (RQ >0.05)

       Acute LOCs for estuarine/marine fish are not exceeded; peak EECs for all major crops are
well below the NOAEC value (RQ range: <0.003 to <0.02). No estuarine/marine chronic fish
data were submitted, so a NOAEC value was estimated based on the  assumption that the acute-to-
chronic NOAEC ratio for estuarine/marine fish is the same as for freshwater fish. Based on the
estimated NOAEC value, chronic RQ values for estuarine/marine fish, ranging from 0.02 to 0.18,
are less than the chronic LOCs. Acute and chronic LOCs for estuarine/marine invertebrates are
exceeded for all major crops modeled (acute RQ range: 0.08 to 0.64;  chronic RQ range: 6.7 to
52). Estuarine/marine invertebrates appear to be much more sensitive to fluoxastrobin, with acute
and chronic  RQs approximately two and 290 times higher than their freshwater counterparts.

Aquatic Plants

Toxicity

       Based on data  using duckweed, and freshwater green algae, fluoxastrobin and its
degradates are classified as practically non-toxic to non-target aquatic plants.
                                            18

-------
       All acute non-endangered and endangered species RQs are less than LOCs for both
vascular and non-vascular plants. The range of RQ values for both vascular and non-vascular
aquatic plants is 0.004 to 0.43.

Exposure

       The exposure data that were used for aquatic animals were also used for aquatic plants.

Risk

       Aquatic plant risk to non-vascular plants was evaluated based on marine diatom (S.
capricornatum) toxicity studies using fluoxastrobin and its degradates HEC 7155 and HEC 7180.
Vascular plant risk was based on duckweed (L. gibba) toxicity studies performed using
fluoxastrobin technical only. For aquatic vascular and non-vascular plants, peak EECs were
compared to acute EC50 and NOAEC toxicity endpoints to derive acute non-endangered and
endangered species RQs, respectively.

       The acute non-endangered and endangered species RQs that were calculated for aquatic
vascular and non-vascular plants are summarized in Table 18.

       All of the fluoxastrobin acute non-endangered or endangered species RQs are less than the
LOCs for vascular and non-vascular aquatic plants, so no level of concern is reached. The range
of RQ values for both vascular and non-vascular aquatic plants is 0.004 to 0.43.  Aquatic EECs
for all major crops were well below available toxicity endpoint values for the fluoxastrobin
degradates HEC 7155 and HEC 7180, as well. Therefore, fluoxastrobin degradates are not a
concern for aquatic organisms and plants.

Risk to Endangered Species

       The preliminary risk assessment for endangered species indicates that fluoxastrobin
exceeds the endangered  species LOCs for the following combinations of analyzed uses and
species:
                                            20

-------
•      Use of fluoxastrobin on the following crop scenarios indicate an exceedance of the
       endangered species LOG for freshwater fish: Maine potatoes (ground and aerial
       application), Florida tomatoes, peanuts, and turf (at the maximum application rate of 4
       times per year).

•      Use of fluoxastrobin on Idaho potatoes (aerial application only), Maine potatoes (ground
       and aerial application), tomatoes, peppers, cabbage, peanuts, and turf (at maximum
       [4x/year] and reduced [2x/year] application rates) indicate endangered LOG exceedances
       for endangered freshwater invertebrates.

       Use of fluoxastrobin on Idaho and Maine potatoes (aerial and ground application),
       tomatoes, peppers, cabbage, peanuts, and turf (at maximum [4x/year] and reduced
       [2x/year] application rates) indicate endangered acute and chronic LOG exceedances for
       estuarine/marine invertebrates.

•      Use of fluoxastrobin on Maine potatoes (ground and aerial application), Florida tomatoes,
       peppers, cabbage, peanuts, and turf in Florida (at maximum [4x/year] application rates
       only) and Pennsylvania (for applications of both 4 and 2x/year)  indicate chronic LOG
       exceedances for estuarine/marine mollusks.

       The list of endangered/threatened freshwater fish species where potatoes, tomatoes,
peppers, and peanuts are grown is comprised of 84 different species representing 36 States.  The
three States with the largest number of endangered/threatened freshwater fish species include
California, Washington, and Oregon. Within these States, the majority of endangered/threatened
fish species are salmon and steel head (Orcorhynchus sp.).  The predominant endangered fish
species in Florida and North Carolina, where tomatoes, peppers, and peanuts are grown, is the
sturgeon (Acipenser sp.).

       The list is of freshwater invertebrates is primarily comprised of bivalves (70% of all listed
invertebrates; present in 20 States), crustaceans (i.e., amphipods, crayfish, and shrimp) (-19 of all
listed invertebrates; present in 6 States), and snails (~11%  of all listed invertebrates; present in 2
States). While the majority of listed freshwater invertebrates are bivalves, the amphipod
(Gammarus acherondytes) was listed as endangered in Illinois.  The identification of an
endangered amphipod is a factor because this species was identified as the most sensitive
freshwater invertebrate from the available effects data.  It appears, however, that the endangered
amphipods in Illinois are present only in caves, where pesticides are not likely to be present in
water at concentrations that would cause adverse effects.

       The Agency's levels of concern for endangered and threatened freshwater fish and
invertebrates and estuarine/marine invertebrates and mollusks are exceeded for the use of
fluoxastrobin. However, the Agency recognizes that there are no Federally listed
estuarine/marine invertebrates/mollusks.

       The registrant must provide information on the proximity of Federally listed freshwater
fish and invertebrates to the fluoxastrobin use sites.  This requirement may be satisfied in one of

                                           21

-------
three ways: 1) having membership in the FIFRA Endangered Species Task Force (Pesticide
Registration [PR] Notice 2000-2); 2) citing FIFRA Endangered Species Task Force data; or 3)
independently producing these data, provided the information is of sufficient quality to meet
FIFRA requirements.  The information will be used by the OPP Endangered Species Protection
Program to develop recommendations to avoid adverse effects to listed species. The registrant has
satisfied this requirement using option #1 above.

7.     SUMMARY OF REGULATORY POSITION AND RATIONALE

       Available data provide adequate information to support the conditional registration of
fluoxastrobin technical and the proposed end-use product. Fluoxastrobin technical has a
relatively low toxicity fungicide, and there is reasonable certainty that no harm will result to the
general  population or to infants and children from aggregate exposure to the proposed uses on
peanuts, tuberous and corm vegetables, leaf petiole vegetables, fruiting vegetables, turf and seed
treatment (potato, peanut and turf).  The results of the risk assessment suggest the potential for
direct effects to endangered freshwater fish, and both endangered and non-endangered freshwater
invertebrates, estuarine/marine invertebrates, and mollusks.  In addition, in order to reduce the
uncertainties associated with the risk assessments, additional studies and data will be required as
a condition of registration.

       Although fluoxastrobin is a member of the strobilurin group that includes already
marketed active ingredients, the Agency believes that growers would benefit from a new active
ingredient that can be an effective disease management tool for both curative and preventative
purposes.  In many cases, the efficacy of fluoxastrobin will be  comparable to others currently on
the market. However, diverse qualities of strobilurin fungicides suggest that there can be a
valuable place for this strobilurin active ingredient for some important diseases. In addition, new
chemicals, especially with similar attributes, increase competition and should lower price.  Thus,
growers will receive benefits through lower production costs which, presumably, would be passed
on to the consumer. Therefore, the registration of fluoxastrobin is considered to be  in the public
interest.

8.     SUMMARY OF CONFIRMATORY DATA REQUIREMENTS

       Available data provide adequate information to support the conditional registration of
fluoxastrobin and establishment of the associated tolerances for residues. However, in order to
reduce the uncertainties associated with the risk assessments, the following studies or data will be
required as a condition of registration:

•      Submit additional information concerning the mouse immunotoxicity subacute feeding
       study.

       Sediment-bound fluoxastrobin is persistent (half-life =  141 days), and concentrations in
       suspended or bottom  sediments are likely to be higher than those of the sediment
       interstitial pore water and/or water column.  Given the potential risks to freshwater and
       estuarine/marine invertebrates based on fluoxastrobin concentrations in the water column,

                                            22

-------
       acute (10-day) and chronic (28-day) sediment toxicity testing, as described in the OPPTS
       850.1735 and 850.1740 protocols, will be required in order to reduce uncertainties and
       evaluate risks to freshwater and estuarine/marine sediment dwelling organisms.
