What describes pesticides that can only be applied under the supervision of a certified applicator?

The description of pesticides that can only be applied under the supervision of a certified applicator is accurately captured by the term "restricted-use pesticides." This category includes products that pose a higher risk to human health or the environment compared to general-use pesticides. Due to their potential hazards, restricted-use pesticides require applicators to undergo specialized training and attain certification to ensure they apply these chemicals safely and effectively.

For example, these pesticides might contain active ingredients that are particularly toxic, have a high potential for environmental contamination, or could cause serious harm if misused. Thus, the oversight of a certified applicator is crucial to mitigate these risks and ensure compliance with safety regulations and best practices.

In contrast, other terms such as limited-use, endangered-use, and controlled-use pesticides do not correctly signify the regulatory requirement for certified applicator supervision as established for restricted-use pesticides. These alternatives may pertain to different classifications or usage restrictions, but they lack the specific requirement for certification that is essential for restricted-use pesticides.
