Farmers and ranchers are familiar with noxious weeds—those invasive weeds that pose threats to the environment, people, and animals.  Noxious weeds have always been a concern for agriculture due to their ability to affect crop yields and soil and livestock health.  Nearly all states in the U.S. have enacted laws that list prohibited noxious weeds and assign responsibility for eradicating prohibited noxious weeds in certain circumstances.   These laws attempt to reduce the potential of noxious weed invasions to neighboring lands.  This compilation presents the statutes for each state that has a noxious weed law.  Simply click on a state’s image in the map below to locate the laws for the state.

This compilation is the result of a collaborative effort between the National Agricultural Law Center and The Ohio State University Agricultural & Resource Law Program.  Further, it is based upon work supported by the National Agricultural Library, Agricultural Research Service, U.S. Department of Agriculture.
