Bulletin No 24-01
*To:* Cannabis Industry Members
*From:* WSLCB and WSDA
*Subject:* Updated List of Pesticides Allowed for Use on Cannabis in the Production of High THC Cannabis
The Washington State Department of Agriculture (WSDA) has recently updated the list of pesticides that are allowed for use on cannabis in the production of high-THC cannabis in Washington State, based on criteria previously established by WSDA.
* WSDA has added 3 new Section 3 pesticides and 1 new Section 25(b) pesticide to the list of allowable products for a total of 4 new products.
* WSDA removed 12 Section 3 pesticides and 7 Section 25(b) pesticides from the list for a total of 19 products removed. See details for those removed in the tables below.
* The updated list contains 237 Section 3 pesticides and 82 Section 25(b) pesticides, for a total of 319 products allowed for use on cannabis in the production of high-THC 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 registered for distribution in Washington is available from the WSU PICOL database [ [link removed] ].
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 1 new active ingredient ("Metarhizium brunneum" (formerly known as "Metarhizium anisopliae") Strain F52) were added to the list. Most of the pesticides that were added to the list contain active ingredients that were already allowed 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.
