N.J. Stat. § 4:7-32
A car, box, bale or parcel of nursery stock shipped into this state unaccompanied by a certificate as required by section 4:7-30 of this title, may be seized and detained by the department wherever found, whether in the hands of a common carrier or in the hands of the consignee or his agent.
Such stock may be detained until it has been inspected and found free from dangerously injurious insect pests and from such as in the judgment of the department are liable to become so.
The department shall destroy any stock so examined which is found to be so infested and shall require such as may not be actually infested to be submitted to the treatment necessary to make it safe and the insects that may be harbored in or on it, harmless.
