Iowa Code § 177A.11
Whenever the state entomologist shall find that there exists outside of this state any insect pest or disease, and that its introduction into this state should be prevented in order to safeguard plants and plant products in this state, the state entomologist is authorized to quarantine and promulgate quarantine restrictions covering areas within the states affected by the pest and may adopt, issue, and enforce rules supplemental to such quarantines for the control of the pest. Under such quarantines, the state entomologist or the state entomologist's authorized agents may prohibit and prevent the movement within the state without inspection, or the shipment or transportation within the state, of any agricultural or horticultural product, or any other material of any character whatsoever, capable of carrying any dangerously injurious insect pest or disease in any living state of its development; and, in the enforcement of such quarantine, may intercept, stop, and detain for official inspection any person, car, vessel, boat, truck, automobile, aircraft, wagon, vehicles or carriers or any container, material, or substance believed or known to be carrying the insect pest or plant disease in any living state of its development in violation of said quarantines or of the rules issued supplemental thereto, and may seize, possess, and destroy any agricultural or horticultural product or other material of any character whatsoever, moved, shipped, or transported in violation of such quarantines or the rules.
