B. The Board may establish a statewide quarantine and adopt regulations pertaining to regulated articles and conditions governing movement, under which the Commissioner shall proceed to eradicate or suppress and prevent the dissemination of noxious weeds in the Commonwealth, and shall adopt other regulations as are necessary to carry out the purpose of this chapter. The Board may adopt regulations governing the conditions under which a permit is required to move, transport, deliver, ship, offer for shipment, sell, or offer for sale into or within the Commonwealth any noxious weed or part thereof. The Board may adopt regulations governing the movement of regulated articles entering the Commonwealth from without. Following the establishment of a quarantine, no person shall move any noxious weed or any regulated article described in the quarantine from any regulated area without a valid permit or certificate, if required. Subsequent to the declaration of a quarantine by the Board, the Commissioner shall limit the application of the regulations pertinent to such quarantine to the infested portion of the Commonwealth and appropriate environs, which would be known as the regulated area and may, without further hearing, extend the regulated area to include additional portions of the Commonwealth upon publication of a notice to that effect in a newspaper distributed in the extended area or by direct written notice to those concerned.
