Laws and Regulations
National Plant Board.
The U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Plant Protection and Quarantine Program (USDA APHIS PPQ) and the plant health agencies in each of the 50 states, regulate the shipment of nursery and greenhouse stock in an effort to minimize the spread of harmful insects, diseases, and other pests. The Federal & State Quarantine Summaries is designed as a reference tool for nursery stock growers, brokers, purchasers, and others involved in the buying selling, and interstate transport of nursery and greenhouse plant crops. It outlines the basic quarantine and other plant health requirements of APHIS, all 50 states, and the Commonwealth of Puerto Rico and Guam. The information presented here is designed as an aid to help users avoid costly delays, rejections of plant material shipments, and introduction of harmful pests into new areas.

This annually updated publication contains information about the various State
labeling requirements and prohibitions of noxious-weed seeds and shows the scientific
names and common names according to the law and regulations of the particular
State in which the seed is noxious (by State and Appendices - common and scientific name cross reference).
