Estimated Annual Agricultural Pesticide Use
County-level pesticide use estimates
Preliminary pesticide use estimates*
Beginning 2015, the provider of the surveyed pesticide data used to derive the county-level use estimates discontinued making estimates for seed treatment application of pesticides because of complexity and uncertainty. Pesticide use estimates prior to 2015 include estimates with seed treatment application.
Preliminary pesticide use estimates without California data**
State-level pesticide use estimates by major crop and crop groups
High Estimate Agricultural Pesticide Use by Crop Group 1992 to 2015
Low Estimate Agricultural Pesticide Use by Crop Group 1992 to 2015
Metadata for both datasets is available
*Preliminary estimates are calculated as soon as the data are made available to the U.S. Geological Survey. These
estimates are made by using projected county crop acres from the previous Census of Agriculture and are expected to
be revised upon availability of updated crop acreages in the following Census of Agriculture.
** These files do not include pesticide use estimates for California. Data for California are obtained from the online
Department of Pesticide Regulation-Pesticide Use Reporting (DPR–PUR) database and are typically not available at the
time the preliminary pesticide use estimates are generated for the rest of the U.S.
