Which pesticide category requires careful regulation due to risk factors?

The category recognized as requiring careful regulation due to risk factors is special rule pesticides. This classification is often applied to pesticides that have specific hazards associated with their use, such as potential environmental risks, health concerns for applicators, or severe effects on non-target organisms. Due to these risks, special rule pesticides are subject to additional regulations, restrictions, or guidelines to ensure safe handling, application, and disposal.

By emphasizing safety measures and compliance with regulations, authorities aim to minimize negative impacts on human health and the environment. Other categories, like general-use pesticides or over-the-counter pesticides, while still regulated, do not carry the same level of risk and often do not require the same stringent controls as special rule pesticides.
