## This memorandum summarizes the ecological risks associated with proposed new uses of the insecticide chlorantraniliprole. In addition, the Coragen ® 

## label now includes annual limits for certain crops that reflect multiple crop seasons; risk associated with multiple crop seasons was considered due to the persistence of chlorantraniliprole. The risk assessment considers three products: Altacor ® 

## (Reg. # 352

- 730) , Coragen® 

## (Reg. # 352

- 729) , and PrevathonTM (Reg. # 352

- 844)

. Foliar applications (ground or aerial spray and overhead chemigation) are proposed up to 0.065

- 0.067 lb ai/A for peanut use depending on the product (Corage n® 

## or PrevathonTM); the minimum application interval is three days and the annual limit is 0.2 lb ai/A of chlorantraniliprole containing products. The following label changes were proposed: update stone fruit crops to group 12

- 12 and tree nut crops to group to 14

- 2 (commodities added, no rate change); add green onion subgroup 3

- 07B to the bulb vegetable group (no rate change); increase the tolerance for spice subgroup 19B; and add a last application day before harvest (10 days) for papaya and passionfruit (tropical fruit group). These changes do not affect the risk conclusions from previous assessments and are not considered further. Numerous crops were previously assessed assuming that the annual maximum application rate was equivalent to the seasonal app lication rate (0.2 lb ai/A). The Coragen ® 

## label now provides an annual limit for many crops that reflect multiple crop seasons (0.4 lb ai/A

- 0.8 lb ai/A). The single application rates, application intervals, and seasonal rates have not changed.

**1. Risk**  **Summary** Risk concerns for the proposed use on peanut and for multiple crop seasons of previously assessed uses (see **Table 2** ) are the same as previous assessments (i.e., the same taxonomic groups) ; however the RQs for multiple crop seasons are higher than single crop seasons. There is a risk concern for direct effects on listed and non

- listed aquatic invertebrates (acute and chronic). Risk to terrestrial invertebrates is a concern considering the application rates, the submitted toxicity

data, and the mode of action of chlorantraniliprole as an insecticide. Finally, potential risks to listed terrestrial plants cannot be precluded at this time because a definitive NOEC or EC 05 

## has not been established for dicots. Risk of direct effects to other aquatic and terrestrial organisms is below the Agency screening levels of concern (LOC). A summary of risk concerns is presented in **Table 1**

### The available data could not preclude potential risk to terrestrial plants: dicots (listed and non

- listed species). b

### RQs were not calculated due to lack of a standard quantification methodology. Therefore, the ‘LOC exceedance’ wa s based on lines of evidence including application rate, toxicity data, and the mode of action of chlorantraniliprole. 

## 2. **Data Gaps** Risk quotients (RQs) could not be calculated for listed dicots (terrestrial plants) because a NOEC or EC 05 

## was not established in the available Tier 1 or Tier II seedling emergence studies. Risk to listed dicots will be assumed until data is made available that defines a NOEC for dicots. **3. Summary of Proposed Use**  Foliar applications (ground or aerial spray and overhead chemigation) are proposed up to 0.065

- 0.067 lb ai/A for peanut use depending on the product (Coragen® 

## or PrevathonTM). The Coragen label does not permit overhead chemigation for use on peanut. The following label changes were proposed: u pdate stone fruit crops to group 12

- 12 and tree nut crops to group to 14

- 2 (commodities added, no rate change); add green onion subgroup 3

- 07B to the bulb vegetables group (no rate change); increase the tolerance for spice subgroup 19B; and add a last application day before harvest (10 days) for papaya and passionfruit (tropical fruit group). Numerous crops were previously assessed assuming that the annual maximum application rate was equivalent to the seasonal application rate (0.2 lb ai/A). The Coragen® 

## label now provides an annual limit for many crops that reflect multiple crop seasons (0.4 lb ai/A

- 0.8 lb ai/A). The single application rates, application intervals, and seasonal rates remain the same as previously assessed with two minor exceptions. **Table 2** summarizes the proposed new use and the

- 10 For most crops, to give a representative window of the growing season, the date of initial application (season 1) was selected as two weeks (14 days) before crop maturation from crop scenario data. When modeling multiple seasons, a 14 day interval was arbitrarily selected to represent the time between the f inal application of the preceding season and first application of the following season. An arbitrary date of June 1 was selected for FL Citrus and the date of crop emergence of May 16 was selected for NC Peanut due to inconsistencies within the crop scenario dates for these crops. For FL Cucumber, November 1 was selected as the initial date of application in order to fit all applications in a given calendar year which is needed to run the model. Crop Scenarios

## 4 **. 2** **. Terrestrial Exposure**  In past assessments there was not a risk concern for mammals or birds even assuming a single application at an annual maximum rate of 0.2 lb ai/A (e.g. DP 397575+). Therefore, there is not a risk concern for the proposed peanut use given the same annual maximum rate; terrestrial exposure was not estimated. However, exposure was estimated for uses with multiple crop seasons. As a screen, two methods and sets of assumptions were used to calculate EECs which are intended solely to capture a range of possible exposure scenarios. (1) Plants may accumulate chlorantraniliprole residues from season to season to the extent that previously treated plant material remains on or off the field. As a screen, EECs were calculated in T

-REX (v 1.5) 1 

## for multiple crop seasons making the assumption that the same plant material is treated season after season (for example, see **Table 4** for the crop scenario resulting in the highest EECs). (2) EECs for subsequent crop seasons are expected to increase over the EECs based on a single crop season even if previously treated plant material is completely removed from the field given that chlorantraniliprole is persistent in soil and that the Coragen label indicates that the product is translocated into the above ground portions of plants after soil applications. Carryover residues could come from either past soil or foliar applications. The Briggs model was used as a conservative screening estimate of exposure due to systemic transport into plant material (details and equations provided in White Paper in Support of the Proposed Risk Assessment Process for Bees **,** September 11

– 14, 2012). For this screening analys is, it was assumed that estimated concentrations would occur throughout a plant. The EEC (0.299 mg/kg plant material) was based on an application rate of 0. 6 lb ai/A (a

Several minor plant incidents were reported in the aggregated incident database for a chlorantraniliprole containing product (Grubex) other than those considered in this assessment and one incident for application of chlorantraniliprole and sulfentrazone (product(s) not identified) . There was also one plant incident involving Grubex in the EIIS database (> 45% effects on plants for a residential application

– certainty of causation is possible). **7 .**  **Ecological Risk 7**  **.1. Terrestrial Organisms**  There is not a risk concern for birds or mammals for the use on peanut or for the assessed multiple crop season uses. Terrestrial Invertebrates As in past assessments, a risk concern for terrestrial invertebrates cannot be precluded. The Agency currently does not have a quantitative method to assess risks of pesticides to non

-target terrestrial invertebrates. However, it is a reasonable assumption that an insecticide would pos e some direct risk to non

-target terrestrial invertebrates, including insects. Second, compared to the proposed application rates (0.065

- 0.099 lb ai/A single maximum rate; 0.2

- 0.8 lb ai/A annual rate), available toxicity data suggest potential direct effects to at least some non

-target insects (e.g., LR50 

## for mortality was < 0.067 lb ai/A for hoverfly). Terrestrial Plants The LOC (1.0) was not exceeded for non

- listed or listed monocots located in dry or semi

- aquatic locations or from spray

drift (RQs < 0.1) in previous assessments of the same application rates. Toxicity has not been defined for dicots (EC 25 

## undetermined and NOEC < 0.0167 lb/A in the available Tier II seedling emergence study). At this time, risk cannot be precluded for dicots (listed and non

- listed). There is not a risk concern for monocots from the proposed use on peanut or the assessed multiple crop season uses. **7.2. Aquatic Organisms**  There is not a risk concern for fish (freshwater and marine/estuarine) or aquatic plants (vas cular and non

-vascular) for the proposed use on peanut or for the assessed multiple crop season uses.

## 12

Aquatic Invertebrates The acute listed species LOC (0.05) was exceeded for freshwater (RQ = 0.34) and marine/estuarine invertebrates (RQ = 0.09) for use on peanut. For all crops with multiple crop seasons, the acute listed species LOC was exceeded for freshwater (RQ = 0.85

- 3.1) and marine/estuarine invertebrates (RQ = 0.25

- 0.91) 4 

## . There is also an acute risk concern for non

listed aquatic invertebrate species (LOC = 0.5) for all multiple crop season uses except strawberry

(non

- listed acute LOC was not exceeded for marine/estuarine invertebrates). There is not a chronic risk concern for aquatic invertebrates for use on peanut. However, the chronic LO C (1.0) was exceeded for use on crops with multiple crop seasons: freshwater invertebrate chronic RQ = 2.2

- 8.1 4 

## and marine/estuarine chronic RQ = 0.4

- 1.5 4 

## . There is a chronic risk concern for aquatic invertebrates for all multiple crop season uses except strawberry (chronic LOC was not exceeded for marine/estuarine invertebrates). **8 .**  **Endangered and Threatened Species Table**  **5** summarizes potential concerns for direct and indirect effects to federally
