Noxious weed
From Wikipedia, the free encyclopedia
Noxious weeds are plant species that have been designated by state or national agricultural authorities as plants that are injurious to agricultural and/or horticultural crops and/or humans and livestock. Most have been introduced into a foreign ecosystem either by accident or mismanagement, but some are also native species. Typically they are plants that are aggressive growing which multiply quickly and adversely affect desirable plants or are somehow injurious to livestock or humans either by contact or when ingested. They are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management and other open lands.
