Federal Noxious Weed Act:
P.L. 93-629 (January 3, 1975) was adopted to prevent foreign weeds from entering and becoming established to the detriment of U.S. crops and livestock. Under this act, the Animal and Plant Health Inspection Service inspects incoming passengers, baggage, and cargo at international airports, seaports and border stations to intercept any of 2,300 listed noxious weeds before they enter the country. If a noxious weed does become established, APHIS has the authority under this act to work with federal, state, and local agencies to confine, eradicate, or control it.
