The Washington State Department of Agriculture (WSDA) has recently updated the list of? pesticides that are allowed for use in the production of high-THC cannabis in Washington State, based on criteria previously established by WSDA.
- WSDA has added 8 new Section 3 pesticides and 13 new Section 25(b) pesticides to the list of allowable products for a total of 21 new products.
- WSDA removed 24 Section 3 pesticides and 14 Section 25(b) pesticides from the list for a total of 38 products removed. See details for those removed in the tables below.
- The updated list contains 245 Section 3 pesticides and 87 Section 25(b) pesticides, for a total of 332 products allowed for use in the production of cannabis in Washington State.?
?
?WPS? and ?HG Only? Columns
WSDA has two columns on the list: (1) Section 3 pesticides that are subject to Worker Protection Standard (WPS) requirements, and (2) Section 3 pesticides that are limited to use by non-commercial ?HG Only? cannabis growers. The products designated as ?HG Only = Yes? may only be used by those individuals authorized to home grow medical-use cannabis.
Products marked as ?HG Only = Yes? may not be used in the commercial production of cannabis.
?
Spray Adjuvants
Spray adjuvants are not included on the list. However, any spray adjuvant that is labeled for use on food crops can be used with an allowed pesticide that is applied to cannabis, if the intended use is authorized by the spray adjuvant label. For example, a spray adjuvant labeled only for use with an herbicide cannot be used with an insecticide or fungicide. Information on spray adjuvants that are registered for distribution in Washington is available from the WSU PICOL database.
?
Please check your stock of pesticides against the list to ensure that you are using an allowed product. Cannabis growers can continue to use any existing stocks of pesticides that were removed from the list, but no new product can be purchased.
?
Pesticides containing two new active ingredients (Sucrose Octanoate Esters and Chitosan) were added to the list. Most of the pesticides that were added to the list contain active ingredients that were already allowed for use in marijuana production.
?
Notes on allowable limitations for certain active ingredients (Azadirachtin, Potassium Silicate, and Hydrogen Peroxide) have been added to the Section 3 Pesticide portion of the list. Users must ensure that pesticide use is within these limitations for the pesticide to be allowable for use on cannabis.
?
Some pesticides are labeled for application to soil or to crop plants, while some pesticides are labeled for application to both soil and crop plants (e.g., insecticides, fungicides). Other pesticides include herbicides labeled for direct application to, and control of, unwanted plants (i.e., weeds). Remember to read, understand, and comply with all applicable label directions and precautions when using any pesticide.
