Screening Level Usage Analysis ( SLUA)

Date: 6/ 2/ 05 What is a Screening Level Usage Analysis ( SLUA)?

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

What does it contain?

  Pesticide usage data for a single active ingredient only.   Agricultural use sites ( crops) that the pesticide is reported to be used on.   Available pesticide usage information ( i. e., does not include all of the United States).   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 by year, averaging across all years, & 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 years, & rounding to the nearest multiple of 5. Note: If the estimated 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 NASS ( United States Department of Agriculture's National Agricultural Statistics Service)   pesticide usage data from 1998 to 2003.   NCFAP ( National Center for Food and Agricultural Policy)   pesticide usage data from 1997 & is only used if data is not available from the other sources.   Private pesticide market research   pesticide usage data from 1998 to 2003.   California DPR data can be requested separately.

What are the limitations to the data?

  Additional registered uses may exist but are not included because the 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 sites ( e. g., turf, post harvest, mosquito control, etc.) are not reported in the SLUA. A separate request must be made to receive these estimates.
