Environmental Risk Branch I Environmental Fate and Effects Division (7507P) Attached is the Environmental Fate and Effects Division (EFED) ecological risk assessment for two newly proposed uses of the fungicide, a cibenzolar - s - methyl. This a ssessment provides a screening level new use assessment to support the proposed uses of a cibenzolar - s - methyl o n turf and as a seed treatment on cotton.2

1. Executive Summary This ecological risk assessment evaluates the proposed two new uses of acibenzolar- s methyl o n turf and as a seed treatment on cotton. The first proposed registration is for the Section 3 new use of the Daconil ACTion (EPA Reg. No. 100 - XXXX , unassigned)) containing the active ingredients chlorothalonil (53.94% a.i.) and acibenzolar - s - m eth yl(0.11% a.i.) for use on turf ( sod farms, golf course turf, lawns around commercial and industrial buildings, and professional and collegiate athletic fields). Chlorothalonil is already registered for the uses included on the proposed label. This as sessment only evaluates potential ecological effects from acibenzolar - s methyl. Interactive effects from the combined exposure of chlorothalonil and acibenzolar - s - methyl are not addressed. The second proposed Section 3 new use registration is for the new seed treatment product Bion 500FS (42.0% a.i., EPA Reg. No. 100 - XXXX , unassigned) on cotton. The maximum total seasonal application rates are 0.14 lbs a.i./acre for turf and 0.0002 lbs a.i./acre for cotton . Acibenzolar - s - methyl (benzo(1,2,3)thiadiazo le - 7 - carbothioic acid - S - methyl ester) is a selective, s ys temic compound that belongs to the benzothiadiazole class of fungicides for the control of bacterial and fungal pathogens. The chemical works s ys temically to increase enzy

mes in the plant , which can degrade fungal and bacterial cell walls. The phy siological process induced by acibenzolar treatment is achieved b y the triggering of sy stemic activated resistance (SAR) within plants. This natural resistance can be induced biologicall y whenever a plant is attacked b y low levels of pathogen inoculum . Acibenzolar - s - methyl (acibenzolar) degrades rapidly by abiotic and biotic processes to its principal metabolite , CGA - 210007 , which is expected to be similar in toxicity to acibenzolar; therefore, this ecol ogical exposure assessment addresses both acibenzolar - s methyl and CGA - 210007. 1.1 Findings of Previous Assessments The most recent risk assessment for acibenzolar was a Section 3 new use ecological risk assessment for the registration of cucurbits and onions (DP Barcode: D351609+, February 12, 2009). Findings of this risk assessment indicated that neither the use of acibenzolar nor its major degradate posed risks to non - target organisms at concern levels .3

1.2 Findings of Currently Proposed Uses Based upon the available data, this current assessment also concludes that the proposed new uses of acibenzolar on turf and as a cotton seed treatment are not expected to pose risks to either non - targeted plants or animals that inhabit terrestrial or aquatic environments at concern levels to the Agency (Table 1) .

Scope of Assessment An abbreviated review was conducted b y EFED for the following reasons.  No new data have been submitted that affect the environmental fate or effects conclusions or modeling inputs .  Proposed application rates, intervals, and seasonal loads are less than previously approved application rates .  No new exposure methods h ave been approved for standard risk assessments since the new chemical assessment was performed in 200 9 . 3. Summary of Proposed Uses Daconil ACTion (EPA Reg. No. 100 - XXXX , unassigned) is a flowable fungicide proposed to be applied as a ground spray for management of bacterial and fungal pathogens on turf ( sod farms, golf course turf (fairway s, tees and greens) , lawns around commercial and industrial buildings, and professional and collegiate athletic fields) . According t o the proposed label , the maximum seasonal application rate on turf is 0.144 lbs . acibenzolar on golf course greens per season. The label allows for a single maximum application of 0.023 lbs. ai of acibenzolar at a minimum application interval of 14 days. Applications less than 0.023 lbs ai require a 7 day minimum application interval. The proposed label does not specify the maximum number of applications. Table 2 summarizes the application rates and methods for the proposed new uses of Daconil ACTi on on turf. Table 2.

Bion 500FS (42.0% a . i ., EPA Reg. No. 100 - XXXX , unassigned) is proposed for seed treatment on cotton targeting nematodes and earl y se ason fungi . The maximum application rate of acibenzolar - s - methyl is 0.0009 mg per seed based on 5,000 seeds per pound. The calculated application rate for acibenzolar as a cotton seed treatment is 0.0002 lbs a.i./A. The calculation for the cotton seed treatment is (0.0009 mg a.i./seed x 5000 seeds / lb = 4.5 mg a.i. / lb seed; 4.5 mg a.i./lb seed x 18 lbs seed / acre = 81 mg a.i./Acre = 0.0002 lbs a.i./Acre). 18 lbs of seed per acre was used as a typical seeding rate for cotton. Because of the very low a pplication rate of 0.0002 for the cotton seed treatment at the recommended plant ing depth of 1.5 inches, potential exposure in surface water would be much lower than those presented for turf. Because no LOC exceedances occurred for turf, the substantially lower application rate of acibenzolar to cotton seeds are not modeled in this assessment. The proposed and registered uses of acibenzolar, the maximum seasonal application rate and target pests are listed in Table 3 . Table 3.

Exposure Characterization 4.1 Environmental Fate and Transport Characterization Laboratory

and field studies indicate that acibenzolar - s - m eth yldoes not have a high potential to leach to ground water nor move to surface water based on its sh ort resident time in aerobic soil. The primary pathway for the degradation of acibenzolar involves cleavage of the thioester to form the carbox yl ic acid derivative 1,2,3 -Benzothiadiazole - 7- carboxylic acid, (CGA 210007). CGA - 210007 has a longer soil residence time, lower Freundlich Kd adsorption values, and is more soluble than its parent, thereby exhibiting greater potential than the parent for lateral a nd/or vertical movement after application. The environmental fate and transport properties of acibenzolar- s - methyl and CGA 210007 are listed in Table 4 . Table 4 .

The major degradate from the h ydroly sis of the ester to the acid in the aerobic soil study is CGA 210007 (maximum of 82.57%). The calculated half - life of CGA - 210007 in the aerobic soil study is 16.5 day s . Anaerobic soil metabolism studies were not required. In the anaerobic aquatic study acibenzolar displayed a biphasic pattern of decline (4 day s followed b y 95 days)(MRID #44537037). CGA - 210007 reached a maximum average sum of 90.89% of the total dose aft er one ye ar of incubation. Under anaerobic conditions in water, CGA 210007 showed very little degradation by

the end of the study

(day 360). The major routes of degradation include aqueous photoly sis (T 1/2 = 0.6 hrs, MRID # 44537034) and photo degradat ion on soil (T 1/2 = 1.0 day s, MRID # 44537035). Acibenzolar - s - methyl is stable to hydrol ys is (MRID #44014252). The hydroly sis studies authors extrapolated the half - life to be 23.1 weeks which is well beyond the duration of the 30 day

study ; therefore acibenzolar is considered stable to hydrolysis. The major degradate observed in the hydroly sis study w as CGA - 21 0007 (up to 100%) . In the soil photoly sis study

CGA 210007 was the major degradate observed (maximum of 60.2%) . C onsiderably

lesser amounts of CGA 210007 were found in the photoly sis in water study (8.4 percent). The major degradate in the photolysis in water study was CO 2 (>33 percent).7

Based on limited data regarding the environmental fate of CGA 21 0007, it is uncertain whether this chemical is susceptible to hydrol ys is, photoly sis, or aerobic aquatic metabolism although in the hydrolysis study decline of the CGA 210007 was minimal . Because degradation by

these processes was assumed not to occur (assumed stable in the modeling runs) , the re sulting environmental concentrations may be overestimates. 4.3 Mobility A dsorption and terrestrial field studies indicate that acibenzolar is not expected to move below the top 3 inches . Acibenzolar’s Koc values range from 492

– 3288; therefore, it is expected to readil y sorb to the soil matrix thus reducing the potential for leaching. Although a cibenzolar would sorb to soils and sediments, degradation is the principal impediment to leaching. The major degradate, CGA 210007, is more mobile and if it reaches depths below which aerobic metabolism is likely , may be found in groundwater due to its substantially longer half - life under anaerobic conditions. CGA 210007 showed very little degradation by

the end of the 360 day

anaerobic metabolism study . Based on the batch equilibrium and aged soil column leaching studies , CGA 210007 has longer resident field times than the parent (aerobic soil half

- life at 16.5 day s) and is considered moderatel y mobile (K oc = 1 38 mg/L, mean) under the FAO classification sy stem . 4.4 Bioconcentration The maxi mum BCF for Acibenzolar was 199x in the viscera (118X whole fish, 48X fillet) reaching steady- state very rapidly (approximately

3 days). Depuration was rapid with less than 10 percent of the steady state value reached at day 28. Therefore, a cibenzolar - s - methyl is not considered highl y bioaccumulative. 4.5 Terrestrial Exposures Exposures to terrestrial plants and animals were modeled by TERRPLANT (Version 1.2.2.2) and TREX (Version 1.4.1), respectively . Inputs for TREX included the maximum seasonal application rates and intervals from Table 5 , EFED’s default foliar dissipation half

- life of 35 day s, which was employed in the absence of foliar dissipation data. Inputs for TERRPLANT included the maximum sea sonal application rates from Table 3 and its water solubility (7.7 mg/L) and drift fraction (1%) data as listed in Table 1 1 . Table 5 .

As sessment Data Warehouse and other sources at the time of the assessment. Therefore, this aquatic exposure a ssessment is based on the model predicted environmental concentrations. 5.2 Modeling Estimates Estimated Environmental Concentrations (EECs) for aquatic ecos ys tems assessments were estimated based on EFED’s Tier II aquatic models: PRZM ( P esticide R oot Z one M odel) and EXAMS ( EXposure Anal ys is M odeling S ys tem). PRZM is used to simulate pesticide transport as a result of runoff and erosion from a 10 - ha agricultural field and EXAMS considers the environmental fate and transport of pesticides and predicts EECs in an adjacent small water body (10,000 - m 2 pond, 2 m deep with no outlet), with the assumption that the small field is cropped at 100%. The model is designed to estimate pesticide concentrations found in water at the edge of the treated field. As such, it provides high - end values of the pesticide concentrations that might be found in ecologicall y sensitive environments f ollowing pesticide ap plication. The linked PRZM EXAMS modeling s ys tem considers multi - ye ar simulations addressing runoff and spray drift from multiple applications. The location of the field is specific to the crop being simulated using site - specific information on the soils , weather, cropping, and management factor s associated with the scenario. The crop/location scenario is intended to represent a high - end exposure site on wh ich the crop is normally grown. Based on historical rainfall patterns, the small water body receive s multiple runoff events during the years simulated. Calculations are carried out with the linkage program shell - PE5V01.pl - which incorporates the standard scenarios developed b y EFED. Additional information on these models can be found at: http://www.epa.gov/oppefed1/models/ water/index.htm . The input parameters used in this assessment were selected from the environmental fate data submitted by the registrant and in accordance with US EPA - OPP EFED water model parameter selection guidelines, Guidance for Selecting Input Parameters in Modeling the Environmental Fate and Transport of Pesticides , Version 2.1, October 22, 2009 . The standard scenarios were developed b y EFED to represent nationwide crop coverage and high - end vulnerable sites to run - off and erosion and therefore pesticide transport. The crop/region specificity of the scenarios may

require that several regional scenarios be run for a given crop depending on the need to capture the most conservative set of results10

based on the differences in precipitation and soil characteristics . The CA, FL and PA turf scenarios were used in the PRZM/EXAMS for modeling proposed turf uses. The crop scenarios and their app lications dates are shown in Table 9 . The initial application dates were selected during wet and warm periods when fungal outbreaks often occur. T here is uncertainty in selecting application dates for acibenzolar use on turf because of the numerous ty

pes of fungi acibenzolar targets and the various times and conditions that result in a fungal outbreak. Table 9. PRZM/EXAMS Aquatic Modeling Scenarios and Initial Application Dates for Proposed Acibenzolar - s - methyl Uses on Turf PRZM Crop Scenario Initial Application Date CA Turf 03/21 FL Turf 08/20 PA Turf 07/01 The label specifies application rates for four turf groups: Sod Farms, Group A Turf ( golf course fairway s, lawns around commercial and industrial buildings, and professional and collegiate athletic f

ields ), Group B Turf (g olf course tees and greens ) . The maximum single application rate for each of the turf groups is 0.023 lbs a.i./A at 14 day intervals. Applications less than 0.023 lbs ai require a 7 day minimum application interval. The p roposed label does not specify the maximum number of applications. The number of applications for each of the turf groupings is assumed for modeling purposes only . The proposed Daconil ACTion label does not specify the maximum number of applications. T he modeled application rates, application intervals, number of applications and maximum seasonal application for each of the four turf groups are displayed in Table 10 . Table 10.

The higher the maximum seasonal application rate the greater the number of applications in PRZM/EXAMS mo deling. 2 Single maximum allowable application per season. The application rate s for CGA - 210007 were determined by dividing the molecular weight of CGA - 210007 (180.2 g/mol) by the molecular weight of acibenzolar - s - methyl ( 210.3 g/mol) ) and then multiplyingthe quotient (0.857) by the highest formation rate of CGA 210007 in any

of the guideline studies for the parent. Sin ce the highest formation of CGA 210007 is 100% in the hydrol ys is study the quotient is multiplied by 1 to determine application rate s for CGA 2 10007 . Since CGA - 210007 is a degradation product, CAM 1 was used to simulate a surface applied chemical. A spray drift value of 0.0 was inputted into PRZM/EXAMX since it is a degradation product. Input parameters used in PRZM/EXAMS modeling of acibenzol ar - s - methyl and CGA - 210007 are shown in Table 11. EPISuite was employed to calc u late the vapor pressure and Henry ’s Law constant for CGA 210007. The EPISuite output file is located in Appendix C . Table 11 .

Ecological Risks Summary 7.1 Risk to Aquatic Plants and Animals The acute and chronic RQ values for aquatic plants and animals are well below the LOC16

( 10 to 1666 time s lower than the LOC s ; Appendix A ). Thus, acibenzolar risk s to aquatic plants and animals are lower than concern levels . 7.2 Risk to birds and mammals T he avian acute toxicity

data indicates that there were no mortalit ies or sub - lethal effects at the limit doses for acibenzolar. Thus, standard avian RQ values for acute, sub - acute, and chronic exposures were not calculated in the Ecological Risk Summary section of this assessment . This is because EFED presumes that there are not LOC exceedances for birds based on the results of the acibenzolar avian acute toxicity test and the low proposed application rates . However, chronic RQs were calculated based on the most sensitive avian chronic toxicity NOAEC of 600 ppm and the highest proposed use rate (wh ich was for turf at 10 applications of 0.014 4 lbs a.i./acre). The highest chronic RQ value calculated was 0. 02 . Based on these RQ values, there are no chronic risks to birds that exceed the Agency ’s L OC. Because there w ere no mortalit ies or sub - lethal effects at the highest treatment levels tested in the acute rat study submitted, standard RQ values for acute exposure were not calculated in the Risk Characterization section of this assessment . This is because EFED presumes that risk to mammals does no t exceed the LOC based on the results of the acibenzolar mammalian acute toxicity test and the low proposed application rates . However, chronic RQs were calculated based on the most sensitive mammalian chronic toxicity NOEAC of 200 mg/kg/body (which was f

or turf at 10 applications of 0.0145 lbs a.i./acre). The highest RQ value calculated was 0.07. The RQ values demonstrate that there is no chronic risk to mammals that exceed the LOC. 7.3 Risk s to Terrestrial Plants Tier I seedling emergence and vegetative vigor studies demonstrated that n one of the ten species exposed to the rate of 0.094 lb a.i./A of a cibenzolar (which is higher that the highest proposed use rate evaluated in this assessment) were affected b y 25% or greater when compared to the study control s for each measured parameter . T herefore, acibenzolar is not considered a risk to listed or non - listed terrestrial plants at the highest proposed use rates at concern levels of the Agency . Thus, a cibenzolar terrestrial plant RQs were not cal culated due to this presumed lack of risk to non - target terrestrial plants. 7.4 Summary of Potential Effects to Non - target Insects Acibenzolar was classified as practically non - toxic based on the acute contact honey bee study (LD 50 >100 μg/bee). T herefore, pollinator protection label language is not required. 8. Endocrine Disruption Potential Acibenzolar does not appear to have significant reproductive and developmental effects in tested organisms which may be a result of disruption of the en docrine s ystem .17

However, until such time as the Agency determines that either the parent chemical or an y of these degradates have the potential to be an endocrine disruptor, this risk assessment has not included an evaluation of the relative ris k of acibe nzolar , degradates for endocrine disruption and as such is a source of uncertainty in this assessment. 9. Threatened and Endangered Species (Listed Species) Concern s Based on available screening level information for the proposed uses of acibenzolar, acute and chronic LOCs for threatened and endangered species are not exceeded for freshwater fish and invertebrates; estuarine/marine fish and estuarine marine invertebrates, mollusks , aquatic plants, terrestrial mammals, insects, birds, and plants .18
