In the past 10 years, use of higher-risk pesticides has markedly declined in both pounds applied and acres treated
Reported pesticide use in California declined by more than 5% between 2021 and 2022, reflecting a longer-term trend, according to the California Department of Pesticide Regulation's most recent annual Pesticide Use Report.
In 2022, 181 million pounds of pesticide active ingredients were applied, mostly to farmland, a 10.4-million-pound decrease over 2021. Cumulative acres treated also decreased by 3.2% year over year. Acres treated totals are cumulative, meaning that if a one-acre field was treated three times in a year, the cumulative acres treated would equal three acres. Analyzing trends using multiple pesticide use metrics, including pounds applied and cumulative acres treated, can offer a more nuanced, complete understanding of pesticide use.
The state requires pesticide use reporting for all agricultural applications and some nonagricultural applications, including those in parks, managed urban landscapes, rights of ways, roadsides and structures. Consumer pesticide use is not reported.
The annual report includes a summary of pesticide use by category, based on the pesticide's potential to cause health or environmental impacts or the type of pesticides. In the past 10 years, use of higher-risk pesticides has markedly declined in both pounds applied and acres treated. In terms of pounds applied, pesticide use decreased in most categories, including:
Over the same period, biopesticide use has increased by 56%. Biopesticides are considered a lower-risk alternative for pest control.
The Pesticide Use Report includes data for California's counties collected by county agricultural commissioners, who receive reports from growers, applicators and others. California's pesticide-use reporting program began in 1990.
