Attached is the ecological risk assessment for the Section3 

## new use request for the use ofthe herbicide mesotrione on asparagus, grass grown for seed, oats, okra, rhubarb, sugarcane, and sorghum. For these uses, we conclude that potential adverse environmental effects to terrestrial and aquatic animals and to aquaticnon-vascular plants are minimal. For use ofmesotrione on sugarcane, levels of concern (LOCs) for aquatic vascular plants are exceeded, indicating potential risk. For all other proposed uses, no aquatic plant LOCs are exceeded. In contrast, levels of concern are exceeded for nontarget terrestrial plants for all proposed uses.

There are several additional issues for your attention which EFED believes are not entirely clearltransparenton the proposed label, and which therefore contributeto uncertainty in our analysis.

## The first has to do with the sugarcaneuse, where application rates are proposed on a "per crop cycle" basis. Once planted, a stand of cane can be harvested several times; after each harvest, the cane sends up new stalks. A singleproduction cycle lasts several years with sugarcane planted once at the beginning ofthe cycle and then harvested multiple times. The maximum labeled application rate per year, then, depends on the grower's interpretation of "crop cycle." If

a pre-emergent applicationis made before new stalks develop after each harvest, the maximum application rate could be applied at least annually, while ifpre-emergent applications are only made before new planting, then applicationfrequency 

## would be lower and so would potential risk to non-target organisms. We recommend that the label be amended to clarify the timing and ffequency of application, and therefore the total number of pounds a.i./A per 

## year. 

## This would accommodate the possibility of crop cycles of varying lengths and the issue of multiple applicationsper year. The proposed sugarcane use was reviewed assuming a total of 0.33 

## lbs. a.i./A per year, based on the assumption of annual harvest, with treatment each time new stalks develop.

The second issue is a lack of clarity in the proposal for the applicationof the Callistoproduct as

a ground or aerial spray. While the label states that aerial applicationis allowed for holders of a "supplementary" label, no such label has been submitted or approved by OPP. The current assessment conservatively assumes aerial application, although this does not affect risk conclusions.

## I. EXECUTIVE SUMMARY

EFED has completed a review of the Section 3 new use request for the use ofmesotrione on asparagus, grass grown for seed, oats, okra, rhubarb, sugarcane, and sorghum. The proposed maximum annual application rates range fi-om0.168 lb a.i.1A to 0.33 lb a.i/A. Current registration includes uses with application rates from 0.188 lb a.i./A to 0.50 lb a.i./A, so proposed

uses are essentially within the range ofthose previously assessed. Additionally, no new fate or toxicity data are available.

For terrestrial organisms,this review does not include a new assessment ofrisk. Instead, we summarize past analysis and risk calculations and describe how they apply to the proposed new

uses. For aquatic organisms, assessment endpoints have not been updated, but estimates of aquatic exposure have been refined using Tier I1 models and so RQs have been recalcuated. Table 1

## 11. PROBLEM FORMULATION



## The purpose ofthis Tier I1 screening-levelecological assessment is to evaluate the risk to nontarget organisms from the proposed new uses ofthe herbicide mesotrione on asparagus, grass grown for seed, oats, okra, rhubarb, sugarcane, and sorghum (sweet and grain). Mesotrione is currently registered for use on corn, cranberries, bush and caneberries, flax, and millet. Past risk
assessmentsconcluded that the registered uses did not exceed acute or chronic levels of concern (LOCs) for nontarget terrestrial or aquatic animals. For plants, levels of concernwere exceeded for vascular aquatic plants and for all terrestrialplant groups and risk was presumed for both endangered and non-endangered species.

This assessment ofthe proposed new uses ofmesotrione will be based on the most recent action, which assessed risk from uses on cranberries, bush and caneberries, flax, and millet (DP Barcode D325840). No new fate or toxicity data have been submitted sincethat assessment, so analysis of the properties of the active ingredient will not be updated and assessment endpoints and modeling inputs will not change. Proposed new uses have maximum seasonal application rates (0.168 lb a.i./A to 0.33 1b a.i./A) essentially within the range of those currently registered (0.188 lb a.i./a to 0.50 lb a.i./A).

For terrestrial exposure,modeling-is not crop specific and estimated environmental concentrations(EECs) fromproposed uses will correspond with thosepreviously determined. Therefore, new modeling will not be conducted. Because EECs and endpoints are not changing, risk conclusionswill be the same as those determined for the previous assessment and will be summarized for the current assessment,

For aquatic organisms, the previous Tier I assessment found the potential for risk to aquatic vascularplants. For the proposed new uses, exposure estimates will thereforebe refined using Tier I1 models. Aquatic EECs will be calculated using the Pesticide Root Zone Model (PRZM, v3.12.2, May 12,2005) coupled (input shell, pe5.pl, Nov. 15,2006) with the Exposure Analysis Model System (EXAMS, v2.98.04.06, Apr. 25,2005). These EECs will be compared to
assessment endpointsto determine potential risk to aquatic plants and animals. Although Tier 11, this assessment is still screening-level and is not intended to represent a site or time-specific analysis. Screening-level assessments are intended to be protective of wildlife on a national level as opposed to being a regionally- or locally-specific.

111. ANALYSIS

A. Use Characterization



## Mesotrioneis a tri-ketone compound used as a systemicpre-emergence and post-emergence herbicide for "the selective contact and residual control ofbroadleafweeds." It is absorbed through the soil by emerging weeds and through the foliage of emerged weeds. Accordingto the registrant, it acts by inhibiting the enzymep-hydroxyphenylpyruvate dioxygenase (HPPD) and thus disrupting the pigment (chlorophyll) biosynthesispathway in susceptible plants.

One proposed action for mesotrione permits new uses of the end use product Callisto on

## asparagus, grass grown for seed, oats, okra, rhubarb, grain sorghum, sweet sorghum, and
sugarcane(DP Barcode D335361). Callisto (Reg. No. 100-1131) is a liquid formulation containing40% mesotrione, or 4.0 lb a.i./gal. This product can be applied through ground or aerial spray1. The otherproposed action permits a new use ofthe end use product Lumax on grain sorghum (DP Barcode D335363). Lumax (Reg. No. 100-1152) is a liquid formulation containing 2.94% mesotrione, or 0.268 lb a.i./gal. Lumax is a mixture co-formulated with atrazine (29.4%) and s-metolachlor(11.0%),but those compounds are not considered in the
current assessment. This product is applied through ground spray only.

Application rates for current and proposed uses are presented in Table 2. The maximum single application rates (0.168 to 0.24 lb a.i./A) and seasonal application rates (0.168 to 0.33 lb a.i./A) forproposed new uses are mostly within the range of those currently registered (Single: 0,188to 0.43 lb a.i./A; Seasonal: 0.1 88 to 0.5 lb a.i./A). The one exception is use of Lumax on grain sorghum, which has a slightly lower applicationrate.

B. Exposure Assessment



## The exposure assessment for the proposed new uses is unchanged frompast assessments (DP Barcodes D253844, DPBarcode D325840), which are summarizedhere. Please see the original documents for more detail.

1. 

## Environmental Fate and Transport Characterization



## Mesotrioneis a mobile compound with limited persistence in soil and aquatic environments. It is acidic and its fate properties have a strong dependence on environmentalpH. In 

## soil, mesotrione dissipatesthrough aerobic metabolism with rates dependent on ambient conditions (tla: 5 to 32 d). Mesotrione had low sorption to soils/sedimentsat all pHs tested 

# (I&: 16.5to 390 mL/g) and would be categorized as moderately mobile to mobile. Terrestrial field dissipation studies showed dissipation half-lives of 2 to14 days and did not find any residues below 6 inches. Mesotrione may reach surface water through drift, runoff, andlor erosion. In aquatic environments, mesotrione is stable to hydrolysis and has limited photolysis but dissipates rapidly through aerobic (tin: 3 to 6 d) and anaerobic (tin: 

## 4 d) metabolism. Based on physicochemical properties, bioconcentrationofmesotrioneis not expected. Likewise, volatilization of mesotrione is not indicated.

Metabolism ofmesotrione led to two major degradates:MNBA, formed through aerobic metabolism at up to 60%, and AMBA, formed through anaerobicmetabolism at up to 60%.



# ' The Callisto label states that aerial application is allowed for holders of a valid supplementary label. No such label has been submitted to or approvedby OPP. Until this label uncertaintyis resolved, this assessmentwill be based on the conservative assumption that aerial use is allowed.

## 2. Aquatic 

## Exposure



## In the previous assessments,estimated exposure concentrations(EECs) for aquatic specieswere determinedusing the Tier I 

## simulation model GENEEC. Because those Tier I 

## EECs exceeded levels of concern for some taxa, 

## the current assessment uses Tier I1 modeling instead. Methods and results are described below.

a. Models

Estimated environmental concentrations(EECs) ofmesotrione in surfacewater fi-omthe proposed new uses were generated using Tier I1 screening simulationmodels, the Pesticide Root Zone Model (PRZM v3.12.2; May 12,2005) and the ExposureAnalysis Modeling System (EXAMS v2.98.04.06; Apr. 25,2005), coupled with the input shell pe5.pl (Nov. 15,2006). PRZM simulates fate and transport ofpesticides on the agricultural field and EXAMS simulates the fate and resulting daily concentrationsofpesticides that reach an adjacent water body through runoff, erosion, and spray drift. Simulations are based on crop-specific scenarios developed to represent environmental conditions at sites at high runoff-vulnerability for pesticide transport to surfacewaters fi-oma particular crop. Exposure is estimated for the maximum applicationpattern to a 10-hafield bordering a 1 -ha pond, 2-m deep (20,000 m3) with no outlet. Using appropriate scenarios linked with local meteorological data, the models are run for 30
years with the reported EECs representing the values that are expected once every ten years, based on the thirty years of daily values generated during the simulation. Models and additional information are available at the EPA's water modeling website, http://www .ma.g;ov/oppefedl /models/water/.

b. Modeling Approach and Input Parameters

For all modeling, input parameters were selected based on EFED input guidance (EFED, 2002). Input parameters represent the parent compound only and are presented below in Table 3. 

## All

uses were modeled based on aerial application.

The scenarios, applicationrates, and application dates modeled for the proposed new uses are presented in Table 4. Surrogate scenarios were employed for uses without crop specific scenarios available. Use on oats is modeled based on the availablewheat scenarios, assumed to be representative because both are grain crops with similar cultural practices. Use on okra is modeled using the availabletomato scenarios; okra is a vegetable crop grown for its hit with a bushy habit, similarto tomatoes. Okra is grown inboth Florida and California, the locations of the tomato scenarios. Use on rhubarb is modeled with the Oregon mint scenario. Oregon has high rhubarb acreage, grown primarily in the Willamette Valley, the location of the Oregon mint scenario. As in the Oregon mint scenario, rhubarb is grown in well-drained sandy loam soils. More detail about these scenarios can be found in the scenario metadata availableon the modeling website.

Application dates are not scenario specific. An applicationwindow was determined based on label recommendations and crop emergence dates. From within this window, the application date when the scenariohad the highest precipitation was chosen to provide a conservative estimate ofpotential runoff.

## Ecological Effects Assessment



## The effects assessment for the proposed new uses is unchanged from the most recent assessment (DP 

## Barcode D325840), which is summarized here. More detail canbe found in that document and in the original new chemical assessment (DP Barcode D253844).

For aquatic animals, mesotrione was found to be practically nontoxic to freshwater fish and invertebratesand to estuarinelmarinefish, and it was slightlyto moderatelytoxic to estuarine/marineinvertebrates. For terrestrial animals, mesotione was 

## categorized as practically non-toxicto birds on an acute oral and subacute dietary basis and practically nontoxic to small mammals on an acute and chronic oral basis. It was found to be practically non-toxic to honeybees on an acute contact basis as well. The most sensitive endpointswere used in calculating risk quotients and are presented below in Table 7 (aquatic animal) and Table 8 (birds, mammals, and honeybees).

The most sensitive endpoints for terrestrial and aquatic plants arepresented in Table 9. 

## As an herbicide, mesotrione is likelyto have effects on plants.

## IV. RISK CHARACTERIZATION

Risk characterizationis the integration of exposure and effects characterizationto determine the ecological risk from the use ofmesotrione and the likelihood of effects on aquatic life, wildlife, and plants based on varying pesticide-use scenarios. For terrestrial organisms, the risk conclusionspresented here are based on conclusions from the previous risk assessment 

## (DP Barcode D325840) which have been appliedto the proposed new uses. For aquaticorganisms, risk conclusions have been updated based on more refined aquatic exposure modeling applied to the proposed new uses. More detail canbe found in that assessment.



## I. AquaticAnimals

Previous risk assessments determined that at an aerial application rate of 0.43 lb a.i.lA, potential risk to aquatic animals was well below levels of concern, with risk quotients (RQs) of <<0.01. RQs for all proposed new uses, which have lower applicationrates, will therefore also be <<0.01. No acute or chronic LOCs are exceeded for fkeshwater fish and invertebrates and no acute LOCs are exceeded for estuarinelmarinefish or invertebrates, so acute and chronicrisk to fish and aquatic invertebrates is expected to be minimal. Chronic toxicity tests are not required

## for estuarinelmarinefish and invertebrates.

2. Aquatic Plants



## In past assessments, RQs for aquatic plants have been calculated for application rates between 0.188 lb a.i./A and 0.50 lb a.i./A as ground applications and for 0.43 lb a.i/A as an aerial application. For non-vascular plants, RQs from the highest annual application rates were well below the LOC. 

## All proposed uses have application rates lower than those previously assessed, and so these new uses will not lead to conclusions ofrisk to non-vascular plants.

Previous assessments used Tier I estimates of aquatic exposure and found that the lowest application rate considered, 0.188 lb a.i./A, led to conclusions ofrisk to vascular aquatic plants, for both endangered and non-endangered species. All proposed new uses have application rates equal to or greater than those currentlyregistered, as well as allowing aerial application,which leads to higher exposure. At the Tier I level, then, the conclusionofrisk will apply to proposed

new uses as well.

To refine the assessment ofrisk to aquaticvascular plants, risk from the proposed new uses has been estimated using Tier I1 

## exposure estimates. These refined RQs are presented below in Table 10. All RQs, both for endangered and non-endangered species, arebelow the LOC 

## of 1 .O, except for those fkom the proposed use on sugarcane. There is potential for risk to endangered and non-endangered aquatic vascular plants from the proposed new use on sugarcane. For all the otherproposed new uses, risk to aquatic vascular plants is expected to be minimal.

## Terrestrial Animals



## New RQs were not calculated for risk to non-target terrestrial animals resulting from the proposed new uses ofmesotrione. Assessment of the previously registered aerial use on corn found that potential risk to terrestrial animals was below levels of concern. All acute RQs for

## birds and mammals were 50.02; all chronicRQs for mammals were <0.01 and for birds were <0.86. The maximum proposed new application rate is less than the previously assessed rate 

# - (0.33 lb a.i./A on sugarcane,compared to 0.43 lb a.i./A on corn,both as aerial applications) so RQs for acute and chronic risk to both birds and mammals will remain below levels of concern. Potential risk to birds and mammals is therefore expected to be minimal. Honeybee toxicity data indicatesthat the risk to non-target terrestrial insects is likely to be low.

## Terrestrial Plants

## 2 0.188 lb a.i./A. RQs from this rate arepresented below in Table 11. 

## At this application rate, RQs for non-listed speciesranged from 0.7 to 37 and for listed species, RQs were between 4.9 

## and 87. All categorieshad RQs 

## 2 2.1, above the LOC of 1, 

## except for non-listedmonocots in adjacent upland areas exposed to mesotrione in runoff, which had an RQ of 0.7. With one exception, the same RQs or higher will apply to all proposed new uses, which have the same or higher application rates and allow aerial application.

The onlyproposed use that will lead to lower RQs is that of Lumax applied to grain sorghum at a maximum annual rate of 0.168 lb a.i./A, ground application only. This lower application rate, thou&, will only change RQs slightly and so will not change the exceedances. For terrestrial plants, then, there is a conclusion ofrisk to all categories of terrestrial plants except for nonlisted monocots in adjacentupland areas exposedto mesotrioneinrunoff.

Appendix B

## Taxonomic Groups Potentially atRisk

1. 

## Risk Quotients



## Risk quotients exceed the LOC for endangered terrestrial plants and vascular aquatic plants. Risk quotients do not exceed acute or chronic LOCs for fish, birds, mammals or aquatic invertebrates. Birds are surrogatesfor potential risk to reptiles and terrestrialphase amphibians, therefore these taxonomic groups are not at risk fiom direct effects. Terrestrial invertebratesare not considered to be at risk, because the mode of action and low toxicity to honey bees. Mesotrioneis not expected to affectthis taxonomic group directly. The risk to terrestrial and aquatic plants is based on a screeninglevel assessment. No refinement of exposureor cooccurrence has been conducted to determine the likelihood of adverse effectsthrough direct or indirect effects.

2. 

## Probit Dose Response



## Probit analysis was not conducted for this screening level assessment.

3. 

## Data Related to under-represented Taxa



## No effects data were availablebeyond those typically obtained for pesticides, including effects data for mammals, birds, fish, invertebrates and plants.

c. Indirect Effects



## Because ofpossible direct effectsto terrestrial and aquatic plants, other listed species mightbe at risk of indirect effects, including effects to critical habitat and essential components ofthe ecosystem.

d. CriticalHabitat



## Any critical habitat near treated sites is potentially at risk through effectsto terrestrial or aquatic plants. This assessment does not include a refinement of exposureto determine the probability that concentrationswill adversely affectplant communities sufficientlyto damage critical habitat. Nor has the co-occurrenceofuse to critical habitats been determined.

e. Co-occurrence Analysis



## This assessment has not determined the likelihood that listed species or their critical habitat are near, or might receive runoff or drift 

## fkom treated sites.
