Montana Plant Quarantine Program
The Montana Department of Agriculture administers and enforces several plant pest quarantines that affect interstate and international movement of agricultural commodities. These quarantines were adopted to prevent the introduction of pests that are not established in Montana and to protect Montana agricultural commodities.
