Identifying weeds is important for early detection and eradication of new weed infestations, containment of existing infestations, prevention of weed spread, and implementation of weed management and monitoring programs.
A variety of resources are available to be used in the identification of noxious weeds. The Nez Perce County weed supervisor has a limited supply of free booklets. In addition, you can follow this link to the Idaho State Department of Agriculture site to see photographs of noxious weeds in different life stages and landscapes, information on its characteristics, and threats posed by these plants. The Idaho Weed Awareness Campaign also includes identification resources.
For more information about weed identification, please contact the Nez Perce County extension office.
