Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
Herbicides (US: / ˈ ɜːr b ɪ s aɪ d z /, UK: / ˈ h ɜːr-/), also commonly known as weed killers, are substances used to control undesired plants, also known as weeds.

It reduces the soil's seed bank or quantity by allowing the weed seeds both opportunity and time to germinate, sprout, and appear before the intended crop is planted. Once the weeds appear, they are easily eliminated by various methods that minimize further ...
Benzobicyclon, was introduced in 2001 for control of broadleaf weeds and some sedges that are problems in rice, that had become resistant to sulfonylurea herbicides. Mesotrione was introduced in 2002 and like sulcotrione is a triketone, so it is effective on the same weeds and crops, but is more potent, making it more useful in mixes with other ...
