Cannabis and Pesticides

Back to Laws and Regulations

The Department of Pesticide Regulation (DPR) enforces laws that govern the sale and use of pesticides in California, including use on cannabis. The Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA) requires DPR to develop guidelines for the use of pesticides in the cultivation of cannabis, provide guidelines on pesticide residue for the Bureau of Cannabis Control, and require that the application of pesticides in connection with the cultivation of cannabis complies with Division 6 of the FAC.

DPR does not publish a list of products for use on cannabis.

No pesticide product is federally registered for use on cannabis. There are however, pesticide products that can be legally used on cannabis in California, provided they meet certain criteria. A pesticide product can legally be applied to cannabis under state law if the active ingredient found in the product is exempt from residue tolerance requirements and the product is either exempt from registration requirements or registered for a use that's broad enough to include use on cannabis.

Many of these products are exempt from registration and are not found in DPR's product database. DPR does not track products which fit the criteria and the user bears the responsibility for ensuring product labels meet the criteria. Additional information on these pesticides can be found in the DPR publication: Legal Pest Management Practices for Cannabis Growers in California, PDF. This document includes additional pest management guidance for cannabis growers.

Some pesticides cannot be used in cannabis cultivation. They include pesticides not registered for a food use in California, California restricted materials which include federally restricted use products, pesticide products with the signal word "Danger," and pesticides found on the groundwater protection list.

California Bureau of Cannabis Control (BCC) is the lead agency for cannabis regulation and developed regulations along with the Department of Public Health (Manufactured Cannabis Safety Branch), and Department of Food and Agriculture (CalCannabis Cultivation Licensing). The three licensing agencies have issued regulations for manufacturing, cultivation, a track-and-trace system, laboratory testing, dispensaries, and other cannabis related activities.
