In pesticide use enforcement, what does the term "restricted material" refer to?

The term "restricted material" specifically refers to substances that pose a greater risk to human health and the environment and, therefore, require special handling and permits for their use. These materials are regulated to prevent misuse and ensure that any application is conducted safely and responsibly.

The reason that restricted materials necessitate special permits and handling is due to factors such as toxicity, the potential for causing harm to non-target organisms, or environmental concerns. This regulatory measure is intended to ensure that only individuals who are trained and certified can manage the application of these substances, which is critical for mitigating risks associated with their use.

In contrast, materials that are ineffective, widely available, or have low toxicity are not classified as restricted because they do not carry the same level of risk or regulatory requirements that necessitate special permits or handling protocols. This distinction is crucial for ensuring proper pesticide management practices.
