Which group of pesticides is exempt from registration because it poses little or no risk to humans and the environment?

Minimum risk pesticides are exempt from registration requirements primarily because they are considered to pose little or no risk to human health and the environment. This designation is significant in regulatory terms, as these pesticides typically contain ingredients that are less hazardous and are often derived from natural sources. The exemption allows for greater ease of use and accessibility for consumers and businesses that may benefit from environmentally-friendly pest control options.

In contrast, restricted-use pesticides require special handling, application, and training due to their higher potential to cause harm if used improperly. Experimental-use pesticides are those undergoing trials and therefore have not completed the full registration process because their safety and efficacy have yet to be fully evaluated. General-use pesticides are regulated but are not exempt from registration requirements, as they are deemed safe for use by the general public under labeled conditions. The distinguishing characteristic of minimum risk pesticides makes them an essential option for those seeking low-risk pest control solutions.
