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).
