Guide list for pesticides and cannabis (products allowed in production of cannabis)

The guide list for pesticides and cannabis was updated June 20, 2024, and is sorted by active ingredient then product name. The intent of the list is to assist growers in distinguishing those pesticide products whose labels do not legally prohibit use on cannabis from those that clearly do not allow use. Please view the “Note” column for special conditions of use. The list is not an endorsement or recommendation to use these products in the production of cannabis in Oregon. Do not hesitate to contact Pesticide staff with questions or for label clarification.

The ODA Pesticides Program conducts biannual reviews of pesticide labels to determine their eligibility for the Cannabis Guide List. If you do not see a pesticide label on the list, but feel as though it would qualify, please notify us at pesticide-expert@oda.oregon.gov or (503) 986-4635, and we will review it at the next label review meeting.
