Pesticide Use Reporting (PUR)
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.
The Pesticide Use Report data can be accessed in three different ways
1. California Pesticide Information Portal (CalPIP)
- California Pesticide Information Portal – Generate customized information from DPR's Pesticide Use Report Database
CalPIP is the most up-to-date source of Pesticide Use Reports data. It includes updates submitted after the Pesticide Use Annual Summary Reports.
- CalPIP data column definitions
- CalPIP glossary terms
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.)
Previous years reports are available, in PDF, to the public upon request. If you would like to request any of those reports, please email PUR.firstname.lastname@example.org with your request.

3. Pesticide Use Report Data
Download Pesticide Use Annual Summary Report data, by year, from DPR's FTP site. Note that this data does not include any updates that may have occurred after the release of the Annual Summary Report. Zip files of data from 1970 through most recent available. Pesticide Use Reports data from 1970-1973 are PDFs of the original microfiche and have not been error-checked or made into tables.
Note: Some internet browsers have recently made changes that may cause errors when downloading, such as Chrome and Edge. We recommend using Firefox or IE if you encounter issues.
