PRESS RELEASE - 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:

Cueva Fungicide Concentrate is Colorado’s first “Special Local Need” registration for hemp. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 24(c) allows states to register additional uses of a federally registered pesticide. These additional uses are for distribution and use within a particular state to meet a "special local need" (SLN).

Applicators using Cueva Fungicide Concentrate under this SLN registration must have both the product label and the SLN label in their possession when applying to hemp. A copy of the SLN label can be obtained from CDA’s website here.

This product cannot be used on marijuana.

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.
