Colorado Adds Product to List of Acceptable Pesticides for Cannabis

Fungicide Fortify 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:

  • Fungicide Fortify

To view the updated list, click here for a pdf or click here for an Excel form. For questions regarding this change, contact Laura Quakenbush at (303) 869-9060 or email [email protected].

The Colorado Department of Agriculture (CDA) is currently reviewing pesticide labels upon request and maintaining a list of products whose label it has reviewed that it believes 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.
