A chemical substance used to destroy or inhibit the growth of plants At the HBEF an experiment was conducted in Watershed 2 where all the trees were cut down and herbicides were applied for three years to prevent the regrowth of any vegetation
chemical substances or living organisms (called bioherbicides) used to kill or control vegetation such as brush, weeds, and competing or undesirable trees (2)
A chemical substance used to prevent, inhibit, or destroy non woody plant growth If its effectiveness is restricted to a specific plant or type of plant, it is known as a selective herbicide If its effectiveness covers a broad range of plants, it is considered to be non-selective or broad spectrum A herbicide is one type of pesticide In common usage, however, often used interchangeably with the words phytocide (plant killer) and silvicide (tree killer)
Any approved chemical or others preparation used to control unwanted vegetation Also called pesticide, phytocide, silvacide Opponents of herbicide usage will commonly use loose terms like poisons or chemicals
A herbicide is a chemical that is used to destroy plants, especially weeds. a substance used to kill unwanted plants. Agent, usually chemical, for killing or inhibiting the growth of unwanted plants (weeds). Modern weed killers are put in two categories, selective (affecting specific plant species) and nonselective (affecting plants generally). These in turn are classified as foliage-applied and soil herbicides. Contact herbicides (e.g., sulfuric acid, diquat, paraquat) kill only the plant organs with which they are in contact. Translocated herbicides (e.g., amitrole, picloram, 2,4-D) are effective against roots or other organs, to which they are transported from aboveground treated surfaces (soil). See also defoliant
