Picloram (005101, 005102, 005104) Case Level
                     Screening Level Usage Analysis (SLUA)
                                 May 02, 2019
                                       
What is a Screening Level Usage Analysis (SLUA)?
 A summary of U.S. usage for a pesticidal active ingredient by agricultural crop.
 The information presented is not proprietary, business confidential, or trade secret. 
What does it contain?
 Pesticide usage statistics for a single active ingredient only.
 Available U.S., national summary statistics for pesticide usage information by crop.
 Average pounds of active ingredient applied  -  Annual average pounds of the pesticide reported applied for each agricultural crop (i.e., for surveyed states, not for the entire United States). Values are calculated by merging pesticide usage data sources together; averaging across all observations within a year for each data source, averaging across data sources within years, averaging across year, and then rounding.  Any surveyed year without reported usage for the AI is included as a value of zero pounds applied in the calculation of the average. Values are rounded using common rounding rules (i.e., the half round up method).  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 place value.  Estimated values of 1,000,000 or greater are rounded to the hundred thousands' place value. (Examples: 478 would be reported as "<500"; 43,873 would be reported as "40,000"; 47,873,901 would be reported as "47,900,000")
 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.  If the estimated value is less than 2.5, then the value is labeled <2.5.
 Maximum percent of crop treated - Value is the single maximum annual average value reported across all data sources, across all years. The value is 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 2008 to 2017. (available at https://quickstats.nass.usda.gov/) 
 Agricultural Market Research Data (AMRD)  -  pesticide usage data from 2008 to 2017.
 California Department of Pesticide Regulation (DPR) Pesticide Use Reporting (PUR) data for 2007 to 2016. (available at http://www.cdpr.ca.gov/docs/pur/purmain.htm)
What should I consider when interpreting the reported data?
 The surveys sample from enough states to represent 80% or more of the crop production, in most cases. In rare cases, the survey may sample fewer states than required to reach 80% of the crop production, such deviations are based on the scope of the survey and availability of resources.
 Usage statistics are included only for surveyed crops with reported, quantitative use of the active ingredient during the sampling period (i.e., 2008 to 2017). 
 Lack of reported usage data for the pesticide on a crop does not imply zero usage. There are several reasons for this.  As with any sampling data, it is possible to some usage may be overlooked. Also, even if usage is noted in data sources, it may not be quantified.  In such instances, site and associated usage are not reported in the SLUA. 
 Additional registered uses may exist but are not included because the available surveys neither collect, nor report, usage for those crops (e.g., small acreage crops).
 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 have reported usage without a registered §3 use.  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).
