Perfluoroalkyl and polyfluoroalkyl substances (PFAS): Department of Pesticide Regulation

California will publicly identify and track pesticides containing intentionally added PFAS.

The law makes PFAS pesticide use more transparent through statewide reporting, annual trend data, and county-level notification.

What the law does

Defines PFAS and PFAS pesticide ingredients, including PFAS intentionally added as active, adjuvant, or inert ingredients.
By January 1, 2028, or when the database with 2026 data is posted, whichever comes first, requires the Department of Pesticide Regulation to flag pesticides containing PFAS ingredients in its online pesticide-use reporting database.
Requires the department to list PFAS as a database category of interest and report PFAS pesticide-use trends annually and in other relevant reporting documents.
Requires the department to publish an online list of registered pesticides containing PFAS ingredients by January 1, 2028, and send it to every county agricultural commissioner.
Requires updates to that list and county notification within 60 days after registration of a new pesticide containing PFAS ingredients.

Pesticide manufacturers, importers, dealers, and registrants whose products contain intentionally added PFAS ingredients.
Farmers and other pesticide users whose reported pesticide use includes PFAS-containing products.
County agricultural commissioners receiving the department's PFAS pesticide lists.

The law requires disclosure and tracking; it does not itself prohibit or phase out PFAS pesticides.
