Colorado adds to list of approved pesticides for cannabis growers

Colorado regulators are allowing four more pesticides to be used in cannabis cultivation.

The state Department of Agriculture sent out an updated list of approved pesticides that now includes:

  • PFR-97 10% ES
  • Long Shadow
  • Rootshield WP
  • Spear-LEP

All four can now be used without violating the Pesticide Applicators’ Act.

According to a news release, the agriculture department evaluates pesticide labels upon request and maintains a list of products whose labels have been reviewed.

Such products may be used on marijuana without violating state regulations as long as growers heed the label directions.

According to the state, the use of unregistered pesticides on cannabis would be a violation of the Pesticide Applicators’ Act.
