METHOMYL (090301) Screening Level Usage Analysis (SLUA) Date: October 19, 2009

What is a Screening Level Usage Analysis (SLUA)?

 Available estimates of pesticide usage data for a particular active ingred ient that is used on agricultural crops in the United States.

 Pesticide usage data obtained from various sour ces. The data are then merged, averaged, and rounded so that the presented info rmation is not proprietary, busine ss confidential, or trade secret. What does it contain?

 Pesticide usage data for a single active ingredient only.

 Agricultural use sites (cr ops) that the pesticide is reported to be used on.

 Available pesticide usage information from U.S. states that produce 80% or more of a crop, in most cases, or less than 80%, in rare cases, depending on the scope of th e survey and available resources.

 Annual percent of crop treated (average & maximum) for each agricultural crop.

 Average annual pounds of the pesticide applied for each agricultural crop (i.e., for the states surveyed, not for the entire United States). What assumptions can I make about the reported data?

 Average pounds of active ingredient applied - Values are calculated by merging pesticide usage data sources together; averaging acr oss all observati ons, then rounding. Note: If the estimated value is less than 500, then that value is labeled <500. Estimated values between 500 & <1,000,000 are rounded to 1 significant digit. Estimated values of 1,000,000 or greater are rounded to 2 significant digits.)

 Average percent of crop treated - Values are calculated by merging data sources together; averaging by year, averaging across all year s, & rounding to the nearest multiple of 5. Note: If the estimated value is less th an 2.5, then the value is l abeled <2.5. If the esti mated value is less than 1, then the value is labeled <1.

 Maximum percent of crop treated - Value is the single maximum value reported across all data sources, across all years, & rounded up to the nearest multiple of 5. Note: If the estimated value is less than 2.5, then the value is labeled <2.5. What are the data sources used?

 USDA-NAS S (United States Department of Agriculture’ s National Agricultural Statistics Service) – pesticide usage data from 2001 to 2007.

 Private pesticide market research – pesticide usage data from 2001 to 2007.

 NPUD 2002 (National Pesticide Use Database) pesticide usage data from the CropLife America Foundation are used only if data are not available from the other sources.

 California Department of Pesticide Regu lation (DPR) Pesticide Use Reporting (PUR) data for 2000 to 2005 when 95% or more of a crop is grown California. What are the limitations to the data?

 Additional registered uses may ex ist but are not included because th e available surveys do not report usage (e.g., small acreage crops).

 Lack of reported usage data for the pesticide on a crop does not imply zero usage.

 Usage data on a particular site may be noted in data sources, but not quantified . In these instances, the site would not be reported in the SLUA.

 Non-agricultural use site s (e.g., turf, post-harvest, mosquito c ontrol, etc.) are not reported in the SLUA. A separate request must be made to receive these estimates.

 Some sites show some use, even though they are not on the label. This usage could be due to various factors, including, but not limited to Secti on 18 requests, existing stocks of the chemical, data collection errors, and experiment al use permits (EUPs).Monday, October 19, 2009 Screening Level Estimates of Agricult ural Uses of Methomyl (090301) Sorted Alphabetically
