The Colorado Department of Agriculture enforces the Pesticide Act, which requires registration of all pesticides with CDA before distribution, with few exemptions.
A "pesticide" is any substance intended for preventing, destroying, repelling or mitigating any pest. This includes:
- Insecticides - products intended to kill or repel insects.
- Fungicides - products intended to kill or prevent the growth of fungi.
- Rodenticides - products intended to kill rats and mice.
- Herbicides - products intended to kill or prevent undesirable plants.
- Animal Repellents.
- Products that treat plant diseases.
- Disinfectants and sanitizers.
- Plant Growth Regulators.
Common household products which claim to kill bacteria and viruses are regulated as pesticides.
Pesticides do not include products used on or inside the humans to treat an illness or disease.
CDA also requires registration of pesticide devices and minimum-risk pesticides (also known as "25(b)s") that the EPA has exempted from federal registration requirements as long as they meet federal requirements. More information on Pesticide Devices and 25(b) minimum-risk products may be found on EPA's website.

Frequently Asked Questions & Topics
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.
Discontinued/Cancelled products: Colorado does not have a "discontinued" status or requirement for pesticide products. Product registrations in Colorado need to be maintained as long as the registrant supports sales by retailers.
Does Colorado register spray adjuvants? Colorado does not register spray adjuvants.
2ee labels: Please submit 2ee labels to cda_pestreg@state.co.us or upload to ALSTAR. We do not send out approval notices or will "accept" a 2ee label. We will contact the submitter if label issues are found.
The Colorado Department of Agriculture provides two options that enable the public to confirm if a pesticide product is registered with CDA currently:
1. The Department of Agriculture uses a web application (AgLicense) to manage product registrations. Anyone can obtain information on currently registered products by going to the website and selecting "Product Search" from the list on the left.
2. The NPIRS website associated with Purdue University combines CDA state registration information with EPA information. This includes information on active ingredients and links to additional EPA information. Some products will also have a link to the CDA file label.
The NPIRS website will be one or two days behind the CDA website, since information is transferred nightly.
- Coloradoans are encouraged to only purchase and use pesticides registered with CDA. This will help them avoid products that do not comply with either EPA's pesticide registration requirements or EPA's minimum risk exemption requirements.
- Colorado's licensed commercial applicators can only use pesticides that are registered with the Colorado Department of Agriculture.
- Distributors and retailers can only distribute pesticides in Colorado that are registered with the Colorado Department of Agriculture.
