Who must apply restricted-use pesticides?

The correct answer identifies that only a certified applicator, or someone working under the supervision of a certified applicator, is permitted to apply restricted-use pesticides. This regulation is in place due to the potential hazards associated with these products, which can be harmful to human health, wildlife, and the environment if used improperly.

Certification ensures that the applicator has undergone the necessary training and possesses knowledge about safe handling, application techniques, understanding labels, and the legal responsibilities associated with using these pesticides. Supervision by a certified applicator provides an additional layer of safety, ensuring that someone knowledgeable is overseeing the application process.

Since restricted-use pesticides have increased potential risks, it is crucial that individuals applying them are well-trained and informed, which is why non-certified individuals are not allowed to apply these substances independently. This regulation aims to protect public health and environmental integrity.
