용도
개요
Chlorsulfuron is one of the first sulfonylurea herbicides developed and commercialized by DuPont. Dr George Levitt and his team at DuPont first synthesized chlorsulfuron in 1976, and it was commercialized for use as a herbicide in 1981. It is currently registered by DuPont in the United States, Canada, the European Union, Russia, the Ukraine, Australia, New Zealand, South Africa, Saudi Arabia, and in several countries of South America. Compared with many other herbicides that are applied at levels of pounds per acre (or kilograms per acre), sulfonylureas are highly effective at use rates of less than an ounce per acre (approximately 6 g per acre for chlorsulfuron).
용도
Chlorsulfuron is used as a postemergence herbicide for the control of dicotyledonous weeds, with excellent safety for wheat and other cereals crops. While chlorsulfuron is primarily used to control weeds in cereals, it can also be used in range and pasture applications. It is currently only used to a minor extent for nonfood industrial applications and right-of-way purposes.
