What defines a restricted-use pesticide (RUP)?

A restricted-use pesticide (RUP) is defined as a product that requires the application to be performed by or under the supervision of a certified applicator. This is due to the potential hazards associated with these pesticides, which may pose risks to human health, the environment, or non-target organisms if not used properly. The requirement for a certified applicator ensures that individuals using these pesticides have the necessary training and knowledge to handle and apply them safely and effectively.

The regulation of RUPs is part of broader efforts to ensure safe pesticide use and to mitigate potential negative impacts from improper handling or application. Therefore, while only agricultural producers may use certain products, this does not encompass the definition of restricted-use pesticides overall. Additionally, RUPs are specifically controlled substances that cannot be applied indiscriminately or by just anyone, which rules out the notion of being applied in any quantity by anyone, and they are indeed subject to specific regulations rather than being exempt from them.
