SEED TRADE BUYERS GUIDE 
NOXIOUS WEEO SEEDS 
P RACTICALLY all of the State Seed Laws name some noxious weed seeds. The 
sale of agricultural seed containing any of the noxious weed seeds is prohibited in 
some of the states. Most states, however, allow a very small percentage to be present. 
Regulations vary in the different states. A complete summary of all state seed laws 
may be found on page 143.
