Washington: Updated List of Pesticides Allowed for Use in Marijuana Production

Here’s the alert sent through Friday….
To: Marijuana Industry Members
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. In addition, WSDA has recently updated the criteria to clarify the allowable post-harvest uses of pesticides in marijuana production.
The WSDA has added 19 pesticides to the list of allowable products, and has removed 17 pesticides because the registrations for their distribution in Washington were voluntarily cancelled, or because the labels were no longer consistent with WSDA criteria.
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 17 pesticides that were removed from the list, but no new product can be purchased.
Pesticides containing 3 new active ingredients [Capric (decanoic) acid, Caprylic (octanoic) acid, Sodium tetraborate decahydrate] 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.
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.
