What does the term "restricted-use pesticide" refer to?

The term "restricted-use pesticide" specifically refers to pesticides that may only be used by individuals who are certified or licensed to apply them. This classification is important for ensuring that these chemicals, which can pose a greater risk to human health and the environment, are handled by trained professionals who understand the necessary safety measures and the potential impacts of their use.

Restricted-use pesticides often include highly concentrated formulations or those that have a high toxicity level. The certification requirement is established to protect the public, agricultural workers, and the ecosystem from improper application that could lead to health risks or environmental harm. While there are pesticides that may have restrictions related to sales, handling, or taxation, the defining characteristic of restricted-use pesticides is the necessity for certification for safe application.
