## ft~~ Science Information and .Analysis Branch Biological and Economic Analysis Division (7503P) Khue Nguyen, Chemical Risk Manager Risk Management and Implementation Branch 1 Pesticide Re-evaluation Division (7508P) This memorandum transmits anupdated Screening Level Usage Analysis (SLUA) report for abamectin (previously completed in 2012). The usage datainthe μpdated SLUA (2015) are an amalgamation ofUSDA/NASS and Private Pesticide Market Research data from 2004 to'2013. The current SLUA shows an increase in usage, in terms ofpounds a.i. and percent crop treated on several crops (almonds, apples, artichoke, cantaloupes, cherries, corn (seed treatment), cotton and cotton seed treatment, grapefruit, grapes, lettuce, onions, oranges, peaches, pistachios and plums/prunes). The SLUA shows a decrease, in terms ofpounds a.i. and percent crop treated, on apricots, green beans, pears, spinach, strawberries, tomatoes and watermelons

. Usage for cabbage, corn, dry beans/peas, peanuts, green peas, pluots and sweet coin were not obsezyed during the reporting time frame for the 2012 SLUA. The**usag~** 'data for the remaining crops did not change with the addition ofthe mostrecent usage data in the 2015 SLUA. For questions, comments and otherusage information requests, please contact me at 703-308- 8140.

. What is a ScreeningLevel Usage Analysis (SLUA)? • Available estimates ofpesticide usage data for a particular active ingredientthat is used on agriculturalcrops inthe United States. • Pesticide usage data obtained from various sources. The data are then merged, averaged, and rounded so thatthe presented information is not proprietary, business confidential, or.trade secret. What does it contain? • Pesticide usage data for a single active ingredient only. • Agricultural use sites (crops) that the pesticide is reportedto be used on. • Available pesticide usage information from U.S. states that produce 80% or more ofa crop, in most cases, orless than 80%, inrare cases, depending onthe scope ofthe survey and available resources. • Annual percent ofcrop treated (average & maximum) for each agricultural crop. • Average annual pounds ofthe pesticide applied for each agricultural crop (i.e., for the states surveyed, not for the entire United States). What assumptions can I make aboutthe reported data? • Average pounds ofactive ingredient applied

- Values are calculated by merging pesticide usage data sources together; averaging across all observations, thenrounding. Note: 

## If the estimatedvalue is less than 500, then that value is labeled <500. Estimatedvalues between 500 & <1,000, 000 are roundedto 1 significantdigit. Estimatedvalues of 1,000, 000 orgreater are roundedto 2 significant digits.) · • Average percent ofcrop treated

- Values are calculated by merging data sources together; averaging by year, averaging across all years, & rounding to the nearest multiple of5. Note: 

## If the estimatedvalue is less than 2.5, then the value is labeled <2.5. 

## If the estimatedvalue is less than 1, then the value is labeled <1. • Maximum percent ofcrop treated

- Value is the single maximum value reported across all data sources, across all years, & rounded up to the nearest multiple of5. Note: 

## If the estimatedvalue is less than 2.5, then the value is labeled <2.5. What arethe data sources used? • USDA-NASS (United States Department ofAgriculture's National Agricultural Statistics Service)- pesticide usage data from 2004 to 2013. • Privatepesticide market research

- pesticide usage data from 2004 to 2013. • CaliforniaDepartment ofPesticide Regulation (DPR) Pesticide Use Reporting (PUR) data for 2004 to 2012. What are the limitations to the data? • Additional registered uses may existbut are not**includ~d** because the available surveys do notreport usage (e.g., small acreage crops). • Lack ofreported usage datafor the pesticide on a crop does n.ot imply zero usage. • Usage data on a particular site may be noted in data sources, but not quantified. Inthese instances, the site would not be reported inthe SLUA. • Non-agricultural use sites (e.g., turf, post-harvest, mosquito control, etc.) are notreported in the SLUA. A separate request must be made to receive these estimates. • Some sites show some use, eventhough they are not onthe label. This usage could be due to various factors, including, butnot limited to Section 18 requests, existing stocks ofthe chemical, data collection errors, and experimental use permits (EUPs).'
