The products can now be used on cannabis without violating the Pesticide Applicators' Act.


The list for pesticides that can be used on cannabis without being a violation of the Pesticide Applicators' Act has been updated. Please note the following products have been added:

We are currently reviewing pesticide labels upon request and maintaining a list of products whose label we have reviewed that we believe could be used on marijuana without violating 35-10-117(1)(i), as long as the applicator follows the label directions.

Please be sure to review the list; pesticide products may be removed from the allowed products list if the registrant has not renewed their pesticide product with the Department. Use of unregistered pesticides on cannabis would be a violation of the Pesticide Applicators' Act.
