Fludioxonil ( 071503 ) Screening Level Usage Analysis (SLUA) Date: August 12, 2010 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 Un ited States.  Pesticide usage data obtained from various sources. The data are then merged, averaged, and rounded so that the 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 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 the 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 b y merging pesticide usage data sources together; averaging across all observations, 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 treate d - Values are calculated by merging data sources together; averaging b y ye ar, averaging across all years, & rounding to the nearest multiple of 5. Note: If the estimated value is less than 2.5, then the value is labeled <2.5. 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 ye ars, & 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 2001 to 200 8 .  Private pesticide market research

– pesticide usage data from 2001 to 200 8 .  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 Regulation (DPR) Pesticide Use Repo rting (PUR) data for 2000 to 200 8. What are the limitations to the data?  Additional registered uses may exist but are not included because the available survey s 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.  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 Section 18 requests , existing stocks of the chemical, data collection errors, and experimental use permits (EUPs).Thursday, August 12, 2010 Screening Level Estimates of Agricultural Uses of Fludioxonil ( 071503 ) Sorted Alphabetically Percent Crop Ttd.
