Washington updates approved pesticide list for cannabis production

The Washington State Department of Agriculture recently updated the list of pesticides that are allowed for use in marijuana production in Washington, based on criteria previously established by the agency.

WSDA added 23 pesticides to the list of allowable products and removed 39 pesticides because the registrations for their distribution in Washington were voluntarily cancelled, or because the labels were no longer consistent with WSDA criteria. All the pesticides that were added to the list contain active ingredients that were already allowed for use in marijuana production.

WSDA recommends growers check their stock of pesticides against the list to ensure that they are using products that are allowed by state regulations. Marijuana growers can continue to use any existing stocks of the 39 pesticides that were removed from the list, but no new product can be purchased.
