What is Cloransulam-methyl?
Definition
ChEBI: The methyl ester of cloransulam. An inhibitor of acetohydroxyacid synthase (AHAS), it prevents the synthesis of amino acids in plants and is used as a herbicide for the control of post-emergence control of broad-leaved weeds in soybeans. It is not approved for use within the European Area.
Metabolic pathway
When 14C-cloransulam methyl is incubated with soils, the degradation proceeds via the hydrolysis of the ester group and O-de-ethylation on the triazolopyrimidine ring to yield the three identified metabolites, cloransulam, 5-hydroxycloransulam methyl, and 5-hydroxycloransulam. These metabolites are significantly less phytotoxic than the parent herbicide.
