The Washington State Department of Agriculture (WSDA) has recently updated the list of pesticides that are allowed for use in marijuana production in Washington State, based on criteria previously established by WSDA.
The WSDA has added 12 pesticides to the list of allowable products, and has removed 15 pesticides because the registrations for their distribution in Washington were voluntarily cancelled, or because the labels were no longer consistent with WSDA criteria.
In addition, WSDA has added two new columns to the list to designate Section 3 pesticides that are subject to Worker Protection Standard (WPS) requirements, and Section 3 pesticides that are limited to use by non-commercial marijuana growers (e.g., use allowed on home grown marijuana) only.
Please check your stock of pesticides against the list to ensure that you are using an allowed product.
Marijuana growers can continue to use any existing stocks of the 15 pesticides that were removed from the list, but no new product can be purchased.
All of the pesticides that were added to the list contain active ingredients that were already allowed for use in marijuana production.
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.
