New Jersey Statutes Title 4. Agriculture and Domestic Animals 4 § 7-12

The department shall, unless it has knowledge of the presence of a dangerous disease precluding such action, issue to any nurseryman or other grower of plants who may request the same, and who may wish to ship plants from one part of the state to another, or from this state to outside territory, a certificate stating that the specific nursery or other plantation is, in general, apparently free from dangerous disease or that it is apparently free from specific diseases which might affect the plants in question, or that a specific shipment is apparently free from dangerous disease. The certificate shall be accepted by any carrier for hire as its warrant for transporting and delivering the material or shipment.
