Information for Pesticide Registrants

Colorado requires registration of all Pesticide Products before distribution in Colorado.

Included products are:

  • EPA-registered pesticides
  • 25(b) minimum risk pesticides exempted by EPA
  • Any device that has or should have an EPA establishment number

Registrations are on a calendar-year basis.

All pesticide product registrations expire on December 31st for the year registration was granted.


Applications for new product registration must be downloaded, filled in, printed, and signed.  As a result of the recent emergence of the COVID-19 virus in Colorado, all Colorado Department of Agriculture state employees are being strongly encouraged to telework from home. In order to ensure the Department can continue to provide necessary services and process new pesticide registration applications uninterrupted, we will accept credit card or e-Check payments and all new registration applications must be submitted via email.

  • A separate application package is required for each product.
  • Multiple products can be sent with one email and one credit card/e-check payment form.
  • Initial application processing usually takes about three to six weeks from receipt until we either register the product or notify the applicant of lack of compliance.
  • Please read the downloadable instructions for complete information before completing the application form.
  • A new registration application cannot be done online at this time.

Pesticide Registrant Information Change Notification Form

What defines a product requiring a separate registration? According to the rules of the Colorado Pesticide Act, for more than one pesticide product to be considered the same pesticide product, each pesticide product must exhibit the same:

  • Product name
  • Registrant name
  • Manufacturer name
  • EPA registration number (for products registered by EPA)
  • Labeling

Please note that if the registrant or manufacturer name displayed on the label changes this becomes a new product that requires a new registration application.

Kits/Co-Packs: When two pesticide products are being sold packaged together or when a pesticide or device is sold packaged together with a non-pesticide, the final product is often distributed under a different product name and/or with additional label claims. In these cases, Colorado would consider the kit or co-pack to be a different product requiring its own separate registration.
