Colorado OK’s Pesticides for Use in Cannabis

Brian D. Sparks Posted by Brian Sparks|December 15, 2021

The Colorado Department of Agriculture recently updated its list of pesticides that are permitted for use on cannabis. The following products have been added:

  • Long Shadow from Circadian Crop Sciences
  • PFR-97 10% ES from Certis USA
  • Spear-LEP from Vestaron Corporation

According to the CDA, “the list is intended to assist Colorado cannabis growers in identifying which pesticides can be used legally in accordance with the Pesticide Applicators’ Act and its Rules in the production of cannabis. It is not an endorsement or recommendation to use these products in the production of cannabis in Colorado. These products have not been tested to determine their health effects if used on cannabis that will be consumed and thus the health risks to consumers are unknown.”
