Attached is the ecological risk assessment for the Section 3 new use request for the use of the 

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 aquatic non-vascular plants are minimal. For use of mesotrione 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 

clearltransparent on the proposed label, and which therefore contribute to uncertainty in our 

analysis. 

TEXT SEARCHABLE DOCUMENT
The first has to do with the sugarcane use, 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 single production cycle lasts several years with sugarcane 

planted once at the beginning of the 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 application is made before new stalks develop after each harvest, the maximum 

application rate could be applied at least annually, while if pre-emergent applications are only 

made before new planting, then application frequency 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 

applications per 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 application of the Callisto product as 

a ground or aerial spray. While the label states that aerial application is 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 of mesotrione on 

asparagus, grass grown for seed, oats, okra, rhubarb, sugarcane, and sorghum. The proposed 

maximum annual application rates range fi-om 0.168 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 of those previously assessed. Additionally, no new fate or 

toxicity data are available. 

For terrestrial organisms, this review does not include a new assessment of risk. 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 presents the risk conclusions for all categories.

11. PROBLEM FORMULATION 

The purpose of this Tier I1 screening-level ecological assessment is to evaluate the risk to nontarget organisms from the proposed new uses of the 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 

assessments concluded that the registered uses did not exceed acute or chronic levels of concern 

(LOCs) for nontarget terrestrial or aquatic animals. For plants, levels of concern were exceeded 

for vascular aquatic plants and for all terrestrial plant groups and risk was presumed for both 

endangered and non-endangered species. 

This assessment of the proposed new uses of mesotrione 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 since that 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) from proposed uses will correspond with those previously determined. 

Therefore, new modeling will not be conducted. Because EECs and endpoints are not changing, 

risk conclusions will 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 

vascular plants. For the proposed new uses, exposure estimates will therefore be 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 endpoints to 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 

Mesotrione is a tri-ketone compound used as a systemic pre-emergence and post-emergence 

herbicide for "the selective contact and residual control of broadleaf weeds." It is absorbed 

through the soil by emerging weeds and through the foliage of emerged weeds. According to the 

registrant, it acts by inhibiting the enzyme p-hydroxyphenylpyruvate dioxygenase (HPPD) and 

thus disrupting the pigment (chlorophyll) biosynthesis pathway 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. 100-1 13 1) is a liquid formulation 

containing 40% mesotrione, or 4.0 lb a.i./gal. This product can be applied through ground or 

aerial spray1. The other proposed action permits a new use of the end use product Lumax on 

grain sorghum (DP Barcode D335363). Lumax (Reg. No. 100-1 152) 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 (1 1.0%), 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) 

for proposed new uses are mostly within the range of those currently registered (Single: 0,188 to 

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 application rate. 

B. Exposure Assessment 

The exposure assessment for the proposed new uses is unchanged from past assessments (DP 

Barcodes D253844, DPBarcode D325840), which are summarized here. Please see the original 

documents for more detail. 

1. Environmental Fate and Transport Characterization 

Mesotrione is a mobile compound with limited persistence in soil and aquatic environments. It is 

acidic and its fate properties have a strong dependence on environmental pH. In soil, mesotrione 

dissipates through aerobic metabolism with rates dependent on ambient conditions (tla: 5 to 32 

d). Mesotrione had low sorption to soils/sediments at all pHs tested (I&: 16.5 to 390 mL/g) and 

would be categorized as moderately mobile to mobile. Terrestrial field dissipation studies 

showed dissipation half-lives of 2 to1 4 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, bioconcentration of mesotrione is not expected. Likewise, volatilization of 

mesotrione is not indicated. 

Metabolism of mesotrione led to two major degradates: MNBA, formed through aerobic 

metabolism at up to 60%, and AMBA, formed through anaerobic metabolism 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 approved by OPP. Until this label uncertainty is resolved, this assessment will be based on 

the conservative assumption that aerial use is allowed.

2. Aquatic Exposure 

In the previous assessments, estimated exposure concentrations (EECs) for aquatic species were 

determined using 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) of mesotrione in surface water fi-om the 

proposed new uses were generated using Tier I1 screening simulation models, the Pesticide Root 

Zone Model (PRZM v3.12.2; May 12,2005) and the Exposure Analysis 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 of pesticides on the agricultural field and EXAMS simulates 

the fate and resulting daily concentrations of pesticides 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 surface waters fi-om a particular crop. Exposure is estimated for the maximum 

application pattern to a 10-ha field 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, application rates, 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 available wheat scenarios, assumed to 

be representative because both are grain crops with similar cultural practices. Use on okra is 

modeled using the available tomato scenarios; okra is a vegetable crop grown for its hit with a 

bushy habit, similar to tomatoes. Okra is grown in both 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 available on the 

modeling website. 

Application dates are not scenario specific. An application window was determined based on 

label recommendations and crop emergence dates. From within this window, the application 

date when the scenario had the highest precipitation was chosen to provide a conservative 

estimate of potential runoff.

estimated using the TerrPlant (v1.2.1; Nov 9,2005) screening model. Estimated exposures for 

ground application are lower than would be estimated for aerial application. Modeling inputs 

and outputs can be found in the most recent assessment (DP Barcode D325840), along with more 

details about the model's assumptions and uncertainties. Upper bound and lower bound EECs,

C. 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 can be 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 

invertebrates and to estuarinelmarine fish, and it was slightly to moderately toxic to 

estuarine/marine invertebrates. For terrestrial animals, mesotione was categorized as practically 

non-toxic to 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 endpoints were 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 are presented in Table 9. As an 

herbicide, mesotrione is likely to have effects on plants. In some categories, the active ingredient 

has more effect when applied with an adjuvant rather than alone.

IV. RISK CHARACTERIZATION 

Risk characterization is the integration of exposure and effects characterization to determine the 

ecological risk from the use of mesotrione and the likelihood of effects on aquatic life, wildlife, 

and plants based on varying pesticide-use scenarios. For terrestrial organisms, the risk 

conclusions presented here are based on conclusions from the previous risk assessment (DP 

Barcode D325840) which have been applied to the proposed new uses. For aquatic organisms, 

risk conclusions have been updated based on more refined aquatic exposure modeling applied to 

the proposed new uses. More detail can be found in that assessment. 

I. Aquatic Animals 

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 application rates, 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 estuarinelmarine fish or invertebrates, so acute and chronic risk to 

fish and aquatic invertebrates is expected to be minimal. Chronic toxicity tests are not required 
for estuarinelmarine fish 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 of risk 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 of risk to vascular aquatic plants, 

for both endangered and non-endangered species. All proposed new uses have application rates 

equal to or greater than those currently registered, as well as allowing aerial application, which 

leads to higher exposure. At the Tier I level, then, the conclusion of risk will apply to proposed 

new uses as well. 

To refine the assessment of risk to aquatic vascular 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, are below 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 

other proposed new uses, risk to aquatic vascular plants is expected to be minimal.

* RQ exceeds the aquatic plant LOC; RQ > 1 .O. 

3. Terrestrial Animals 

New RQs were not calculated for risk to non-target terrestrial animals resulting from the 

proposed new uses of mesotrione. 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 chronic RQs 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 

indicates that the risk to non-target terrestrial insects is likely to be low. 

4. Terrestrial Plants 

In the most recent assessment, risk to terrestrial plants was calculated for ground application at 

rates 2 0.188 lb a.i./A. RQs from this rate are presented below in Table 1 1. At this application 

rate, RQs for non-listed species ranged from 0.7 to 37 and for listed species, RQs were between 

4.9 and 87. All categories had RQs 2 2.1, above the LOC of 1, except for non-listed monocots 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 only proposed 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 of risk to all categories of terrestrial plants except for nonlisted monocots in adjacent upland areas exposed to mesotrione in runoff.

5. Federally Threatened and Endangered Species Concerns 

Dicot 

Appendix B contains the lists of endangered species that are potentially at risk from direct or 

indirect effects. There is a list for each crop site. Note that this is just a list based on a screening 

level assessment and based on the LOCATES database which associates species with crops if 

they could occur in the same county. Further refinement would be needed to determine if 

exposure is likely based on co-occurrence.

listed 

The action area is the area in and around potentially treated sites where the exposure is expected 

to exceed concern levels for endangered species. In the case of mesotrione, the LOC for 

terrestrial and vascular aquatic plants is exceeded in areas receiving runoff and drift from treated

sites. The distance from the treated field where LOCs might be exceeded has not been calculated 

in this risk assessment. The action area takes into account the potential for sublethal effects and 

indirect effects and possible effects to critical habitat. 

b. Taxonomic Groups Potentially at Risk 

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 surrogates for potential risk to reptiles and terrestrial phase amphibians, 

therefore these taxonomic groups are not at risk fiom direct effects. Terrestrial invertebrates are 

not considered to be at risk, because the mode of action and low toxicity to honey bees. 

Mesotrione is not expected to affect this taxonomic group directly. The risk to terrestrial and 

aquatic plants is based on a screening level assessment. No refinement of exposure or cooccurrence has been conducted to determine the likelihood of adverse effects through 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 available beyond those typically obtained for pesticides, including effects 

data for mammals, birds, fish, invertebrates and plants. 

c. Indirect Effects 

Because of possible direct effects to terrestrial and aquatic plants, other listed species might be at 

risk of indirect effects, including effects to critical habitat and essential components of the 

ecosystem. 

d. Critical Ha bitat 

Any critical habitat near treated sites is potentially at risk through effects to terrestrial or aquatic 

plants. This assessment does not include a refinement of exposure to determine the probability 

that concentrations will adversely affect plant communities sufficiently to damage critical 

habitat. Nor has the co-occurrence of use 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.
