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.

Who can apply?

  • Students currently enrolled in a cannabis-related program at an accredited university or college.
  • Cannabis executives at licensed social equity cultivation, extraction/processing, retail, manufacturing/brand businesses (or awaiting application approval).

Don’t miss out on this potentially life-changing opportunity.

The state may remove pesticide products from the approved list if registrants fail to renew a pesticide product with the ag department.

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