Plant Health

The Plant Health program is located within the Michigan Department of Agriculture and Rural Development’s (MDARD) Bureau of Environment and Sustainability, Pesticide and Plant Pest Management Division. We protect agricultural and environmental resources through the early detection and management of invasive species and the inspection of plants and plant products for pests and diseases, while facilitating international and domestic commerce. Look below for more information on the various Plant Health sections.

Our mission is to safeguard agricultural and environmental resources by proactively managing invasive species, inspecting for plant pests, and supporting commerce.

Michigan's agriculture and natural resources are protected against harmful pests through plant pest quarantines that establish measures aimed at preventing them from being introduced, established or spread throughout the state.

Apiary Inspections

Apiary inspections ensure bees and beekeeping equipment are free of pests before being shipped to other states or countries. This helps to reduce the spread of problematic pests to other places and facilitates the movement of colonies to states in need of bees for pollination of crops. We have apiary inspectors across the state available to conduct these inspections for beekeepers who request them.
