Section 25b - Minimum Risk Pesticides are characterized by:

• A. Having a very limited set of ingredients and not required to have an EPA registration number; must be registered with the Colorado Department of Agriculture to be sold in Colorado
• B. Must have an EPA registration and number
• C. Prohibited in all states
• D. Only for veterinary use

Answer: (A)

Pesticides under Section 25(b) are allowed to bypass federal registration because they contain a limited set of ingredients considered to pose very low risk. That exemption means they do not have an EPA registration number. However, to be sold in Colorado, they still must be registered with the Colorado Department of Agriculture and meet state labeling and registration requirements. This combination—limited ingredients plus state registration for sale—is what defines these minimum risk products. The other statements don’t fit because they either imply an EPA registration is required, claim prohibition across the states, or restrict use to veterinary applications, none of which describe Section 25(b) minimum risk pesticides.
