Text files of the data presented in the PDF reports and tables below are available for download


DPR’s Pesticide Use Annual Report includes both short-term and long-term pesticide use trends. Use changes from one year to the next reflect short-term variability in pesticide use. Pesticide use is dependent on many factors that can vary unpredictably year over year, including drought conditions, weather, crop selection and other variables. DPR monitors pesticide use data for longer-term trends to inform actions to mitigate potential impacts to human health and the environment and to inform California’s transition to safer, more sustainable pest management. The table below highlights the 10-year trend line between 2011 and 2020 reflecting increased use of safer, more sustainable lower-toxicity pesticides such as biopesticides and oils (listed at the top of the table with green text) and decreased use in the other use categories (listed in red text).
