The Washington Department of Agriculture (WSDA) released an updated guide list of pesticides that cultivators may use on cannabis. The WSDA also now allows certain uses of pesticides on cannabis post-harvest. The updated list adds 19 allowable products, and removes 17 products due to cancellation of distribution registrations in Washington, or because of labeling criteria. Cultivators should review the list to ensure the all pesticides used by the Cultivator are on the list.
The Oregon Department of Agriculture (DOA) released an updated guide list of pesticides that growers may be able to use on cannabis. The updated list includes 18 additional products that appear not to include chemicals that are prohibited. The DOA publishes the list to help growers choose pesticides that are not illegal.
