USGS Maps

The U.S. Geological Survey (USGS) maintains county-level maps presenting annual agricultural use of more than 500 pesticides in the United States. USGS officials combine farm survey pesticide use data with harvested-crop acreage data from the U.S. Department of Agriculture to obtain pesticide use estimates at a county-level nationwide (California data is drawn from pesticide use data collected by the CA Department of Pesticide Regulation). Maps are available for every year since 1993, and a graph accompanies each map showing annual national use by major crop for the mapped pesticide.
