Which state agency is responsible for regulating pesticide use and sales in Michigan?

The Michigan Department of Agriculture and Rural Development (MDARD) is the correct choice because it has the specific mandate to oversee the regulation of pesticide use and sales in the state. This includes administering and enforcing the laws and regulations pertaining to pesticide application, licensing for applicators, and inspecting the products sold within the state to ensure safety and compliance with established standards.

This regulatory framework is crucial for protecting public health, wildlife, and the environment from potential harms associated with pesticide misuse. MDARD also plays a vital role in educating both consumers and professionals about best practices concerning pesticide application and stewardship.

The other agencies mentioned focus on different domains: for instance, the Department of Natural Resources manages state parks and wildlife resources, the Environmental Quality Board addresses environmental issues broadly, and the Department of Health and Human Services primarily deals with public health matters rather than directly regulating pesticides.
