Pesticide Use Reporting (PUR)

Back to Databases

California’s pesticide use reporting program is recognized as the most comprehensive in the world. In 1990, California became the first state to require full reporting of agricultural pesticide use in response to demands for more realistic and comprehensive pesticide use data. Under the program, all agricultural pesticide use must be reported monthly to county agricultural commissioners, who in turn, report the data to DPR.

California has a broad legal definition of "agricultural use" so the reporting requirements include pesticide applications to parks, golf courses, cemeteries, rangeland, pastures, and along roadside and railroad rights-of-way. In addition, all postharvest pesticide treatments of agricultural commodities must be reported along with all pesticide treatments in poultry and fish production as well as some livestock applications. The primary exceptions to the reporting requirements are home-and-garden use and most industrial and institutional uses.

Pesticide Use Annual Summaries

DPR staff prepare annual data summaries, indexed by chemical or by commodity. The summaries include analyses of pesticide use trends and are available from 1989 to present. (Note: In 1989, full use reporting requirements were not in effect.)

    • These updates include a number of additions and corrections to the data since they were first posted. These updates resulted in a 0.4 percent increase in the total number of records and a 0.05 percent decrease in the total pounds of AI in 2011, and a 0.7 percent increase in the number of records and a 0.4 percent increase in pounds of AI in 2012. The most important corrections were in the data fields site_loc_id, license_no, and grower_id. When the 2011 and 2012 data for these 3 fields were originally transmitted to DPR they were incorrectly left padded with zeros. These data have been changed.
