What is a Restricted Use Pesticide (RUP)?

A Restricted Use Pesticide (RUP) is defined as a pesticide that can only be applied by certified applicators. This classification is due to the potential hazards that these chemicals pose to human health and the environment. The U.S. Environmental Protection Agency (EPA) assigns the RUP designation to substances that may cause serious injury or adverse effects if misused, either through improper application techniques or inadequate understanding of the product's risks.

To ensure safety, the application of RUPs is strictly regulated. Only individuals who have completed specific training and obtained certification are permitted to handle and apply these pesticides. This ensures that those applying these potentially harmful substances understand the necessary precautions, application rates, and safety measures to mitigate risks.

In contrast, pesticides that do not fall under the RUP category can generally be used by the public without the need for special training or certification, which is vital for the understanding of safe application practices. This is why the emphasis is placed on the necessity for certification with RUPs—to prevent misuse that could lead to health issues or environmental damage.
