Wikipedia Meaning and Definition on 'Herbicide'
A herbicide, commonly known as a weedkiller, is a type of pesticide used to kill unwanted plants. Selective herbicides kill specific targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often synthetic "imitations" of plant hormones. Herbicides used to clear waste ground, industrial sites, railways and railway embankments are non-selective and kill all plant material with which they come into contact. Smaller quantities are used in forestry, pasture systems, and management of areas set aside as wildlife habitat.
Some plants produce natural herbicides, such as the genus Juglans (walnuts), or the tree of heaven; the study of such natural herbicides, and other related chemical interactions, is called allelopathy.[See more about Herbicide at Dictionary 3.0 Encyclopedia]
