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

1. Highly toxic pesticides

2. Minimum risk pesticides

3. Restricted-use pesticides

4. Biopesticides

The correct answer is: Minimum risk pesticides

Minimum risk pesticides are those considered to pose little or no risk to human health and the environment. These pesticides often have naturally derived ingredients, such as certain plant oils, which are generally recognized as safe. Due to their low toxicity and environmental impact, minimum risk pesticides are exempt from the standard registration requirements that apply to other kinds of pesticides. This exemption facilitates their availability for use without the lengthy review process that more hazardous chemicals undergo. In contrast, highly toxic pesticides are subject to strict regulations and registration because they present significant risks. Restricted-use pesticides also require registration and are subject to more stringent controls due to their potential dangers. Biopesticides, while typically less harmful, still go through a registration process due to the need to evaluate their effectiveness and safety, differentiating them from the minimal risk associated with minimum risk pesticides.
