Abstract

This report provides estimated annual agricultural pesticide use for counties of the conterminous United States for 459 compounds from 1992 through 2009 following the methods described in Thelin and Stone (2013). As described in Thelin and Stone (2013), U.S. Department of Agriculture county-level data for harvested-crop acreage were used in conjunction with proprietary Crop Reporting District (CRD)-level pesticide-use data to estimate county-level pesticide use. Estimated pesticide use (EPest) values were calculated with both the EPest-high and EPest-low methods. The distinction between the EPest-high method and the EPest-low method is that there are more counties with estimated pesticide use for EPest-high compared to EPest-low (Thelin and Stone, 2013). The estimates of annual agricultural pesticide use are provided in tab-delimited files and organized by compound, year, state Federal Information Processing Standard (FIPS) code, county FIPS code, and kg (amount in kilograms).

EPest-high county pesticide-use estimates were divided into tables 1 through 7 by pesticide name:

Table 1: 2, 4-D through Chlordimeform
Table 2: Chlorethoxyfos through Diflufenzopyr
Table 3: Dimethenamid through Gibberellic acid
Table 4: Glufosinate through Metiram
Table 5: Metolachlor through Propazine
Table 6: Propiconazole through Triazamate
Table 7: Tribenuron methyl through Zoxamide

EPest-low county pesticide-use estimates were divided into tables 8 through 14 by pesticide name:

Table 8: 2, 4-D through Chlordimeform
Table 9: Chlorethoxyfos through Diflufenzopyr
Table 10: Dimethenamid through Gibberellic acid
Table 11: Glufosinate through Metiram
Table 12: Metolachlor through Propazine
Table 13: Propiconazole through Triazamate
Table 14: Tribenuron methyl through Zoxamide
