What is the term for a certified applicator who supervises the use of restricted use pesticides?

The correct answer is that a certified applicator who supervises the use of restricted use pesticides is referred to as a commercial applicator. A commercial applicator is specifically trained and certified to apply pesticides, especially those categorized as restricted use due to their potential risks to public health and the environment. This designation indicates a level of responsibility and expertise, allowing the applicator to manage pesticide applications for various clients, ensuring compliance with regulations and safety protocols.

The other terms—private applicator typically refers to individuals applying pesticides for their own agricultural operations, residential applicator does not accurately designate a person supervising pesticide use, and agricultural supervisor may refer to a broader role that doesn't necessarily imply direct certification or supervision in pesticide application—are distinctions that do not match the specific role of supervising the application of restricted use pesticides.
