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

Minimum risk pesticides are exempt from registration because they are considered to pose little or no risk to human health and the environment. This classification is based on criteria established by regulatory agencies that evaluate factors such as toxicity, environmental impact, and exposure levels.

These pesticides usually contain natural ingredients or very low concentrations of active substances that have a long history of safe use. As a result, applicators are not required to go through the extensive and sometimes costly registration processes that are necessary for higher-risk categories of pesticides.

In contrast, restricted use pesticides require special handling and application due to their potential risks. High-risk pesticides are subject to strict regulatory scrutiny owing to their hazardous nature. Conventional pesticides typically undergo thorough evaluation and registration processes due to the potential risks they may pose. Hence, minimum risk pesticides stand out as a safer category that is recognized for its low risk and simplicity in regulation.
