Each year in California, hundreds of millions of pounds of pesticides are applied to crops, soil and water, homes, schools, and workplaces. Our California pesticide use maps provide information about the location and amount of pesticides used for agricultural applications in 1999 in all of California's 58 counties.

To view pesticide use maps for each county, select your local region in the right-side navigation bar from the pull-down menu or click through to the 'interactive map.' Pesticide use maps are only available online.
