Pesticides Registered in Colorado
Know what's what
The list of restricted use pesticides (RUPs) registered for use in Colorado changes regularly. You may want to know if pesticides you intend to use are RUPs to determine whether you need a certain type of pesticide applicator license (learn more about licensing here).
The following link will take you the Colorado Department of Agriculture's page about pesticide registration, where you can view and download the most recent registered pesticide list. You can also find certified pesticide dealers on this page.
