What's New in PUR

PUR Workgroup Meeting: PUR data is used by regulators, researchers, educators, and commodity groups to identify successful alternative pest management systems, promote reduced-risk pest management practices and chemistries, preserve and safeguard endangered species, establish use limits for some pesticides on air and water quality, and protect human health. DPR has invited a diverse array of researchers and regulators who use PUR data in their studies and analyses to showcase how the data informs and supports their work.

Agenda for the event, PDF

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 post-harvest 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)

2. Pesticide Use Annual Summary Reports

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.)

Reports from previous years are available, in PDF format, upon request. If you would like to request any of those reports, please email PUR.inquiry@cdpr.ca.gov with your request.

Select a report from the following list:

  • 2018
  • 2017

3. Pesticide Use Report Data

Download Pesticide Use Annual Summary Report data, by year, from DPR's FTP site. Please 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 years are available. Pesticide Use Reports data from 1970 to1973 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.

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 was originally transmitted to DPR they were incorrectly left padded with zeros. This data has been changed.
