Plant Pest Quarantines
MDARD helps safeguard Michigan agriculture and natural resources against the introduction, establishment, and spread of harmful pests through plant pest quarantines. Plant pest quarantines are legal documents issued by MDARD limiting the movement of specific plant material within, into, or out of the state of Michigan.
Interior plant pest quarantines restrict the movement of specific plant material within the state of Michigan. Exterior plant pest quarantines restrict the movement of specific plant material into the state of Michigan from other states where a plant pest is known to exist.
