Subject: Updated list of pesticides approved for use in cannabis production
The Washington State Department of Agriculture (WSDA) recently updated the list of pesticides approved for marijuana production in Washington State based on criteria previously set by the WSDA.
The WSDA has added six new Section 3 pesticides and ten new Section 25 (b) pesticides to the Approved Product List for a total of 16 new products. 21 Section 3 pesticides and 6 Section 25 (b) pesticides have been removed from the list. The updated list contains 241 Section 3 pesticides and 94 Section 25 (b) pesticides for a total of 335 products.
The WSDA’s list has two columns: (1) Section 3 pesticides that are subject to Worker Protection Standard (WPS) requirements, and (2) Section 3 pesticides that are only used by non-commercial marijuana growers (HG only) may be. The products labeled “Only HG = Yes” may only be used by people who are authorized to grow marijuana for medical purposes at home.
Products marked as “Only HG = Yes” may not be used for the commercial production of marijuana.
Spray aids are not included in the list. However, any spray aid labeled for use in food crops can be used with an approved pesticide applied to marijuana, provided the intended use is approved by the spray aid label. For example, a spray adjuvant that is labeled for use only with a herbicide cannot be used with an insecticide or fungicide. Information on spray aids registered for sale in Washington is available in the WSU PICOL database.
Please check your pesticide inventory against the list to ensure you are using an approved product. Marijuana growers can still use existing stocks of pesticides that have been removed from the list, but no new product can be purchased.
All pesticides added to the list contain active ingredients that have already been approved for marijuana production.
Some pesticides are labeled for use on soil or crops, while some pesticides are labeled for use on soil and crops (e.g. insecticides, fungicides). Other pesticides include herbicides that are labeled for direct application and control of undesirable plants (i.e. weeds). Remember to read, understand, and follow all applicable label directions and precautions when using pesticides.
