Which regulation requires specific conduct for pesticide applicators to protect people and the environment?

Regulation 637 is the correct choice because it outlines the specific conduct expected from pesticide applicators to ensure the protection of human health and the environment. This regulation sets forth guidelines and requirements that applicators must follow when using pesticides, addressing factors such as application methods, safety precautions, and environmental considerations.

The intent of this regulation is to minimize risks associated with pesticide use, including potential harm to non-target organisms, water sources, and the surrounding community. By mandating certain practices and safety measures, Regulation 637 aims to ensure that pesticide applicators operate responsibly and with a clear understanding of the implications of their work on public health and ecological integrity.

Other regulations, while relevant to various aspects of pesticide management, may not specifically focus on the conduct of applicators in a way that directly aligns with the protection of people and the environment. Thus, Regulation 637 stands out as the essential guideline for ensuring responsible pesticide use.
