what is a selective herbicide
Selective herbicide. SELECTIVE HERBICIDE. A selective herbicide is a weed killer that eradicates or stops the development of an invasive weed without damaging other species of plant. Selective herbicides are particularly useful when weeding lawns and turf, as they prevent gardeners from damaging lawn grass.
Herbicides are available in two main types: nonselective and selective. The nonselective variety is used to kill all growth and is generally reserved for agricultural use or for clearing large or heavily overgrown areas. On the other hand, a selective herbicide is used to target certain types of plant life. This form works to curb growth, usually through some type of hormone disruption, and should not affect other vegetation. For the home gardener, a nonselective herbicide is rarely required.
