What is the primary concern when using restricted use pesticides?

The primary concern when using restricted use pesticides is that they may pose risks to human health or the environment. Restricted use pesticides are classified this way because they contain active ingredients or formulations that can be particularly hazardous if not used properly. The potential for acute and chronic effects on human health—such as skin or respiratory irritation, or more serious long-term health issues—and adverse environmental impacts, including harm to non-target species and contamination of water sources, necessitate stricter regulations and oversight.

These pesticides are subjected to more stringent controls to ensure that only trained and certified individuals can apply them, minimizing risks associated with their use. The rationale behind the restrictions is to protect public health and the environment from the dangers posed by these more potent or hazardous chemicals. Therefore, the emphasis on safety and proper handling protocols is key in understanding the regulations surrounding restricted use pesticides.
