Plant Quarantine Act
# Plant Quarantine Act

The Plant Quarantine Act, originally enacted in 1912 (7 U.S.C. 151 et seq.), gave the Animal and Plant Health Inspection Service (APHIS) authority to regulate the importation and interstate movement of nursery stock and other plants that may carry pests and diseases that are harmful to agriculture. This Act has been superseded by the consolidated APHIS statute, the Plant Protection Act of 2000 (7 U.S.C. 7701 et seq.). This authority is particularly important to the agency’s ability to prevent or limit the spread of harmful invasive species within or to a state or region of the United States.
