What is Thifensulfuron methyl?
The Uses of Thifensulfuron methyl
Herbicide.
The Uses of Thifensulfuron methyl
Postemergence herbicide used to control wild garlic and many broad-leaved weeds in barley and spring wheat.
definition
ChEBI: A methyl ester resulting from the formal condensation of the carboxy group of thifensulfuron with methanol. It is used as a post-emergence herbicide for the control of grass and broad-leaved weeds.
Agricultural Uses
Herbicide: A herbicide for postemergence broadleaf weed control in crops for food such as soybeans and cotton. Not listed for use in EU countries.

Environmental Fate
Chemical/Physical. May hydrolyze in aqueous solutions forming methyl alcohol and 3-(((((4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino)carbonyl)amino)sulfonyl)-2- thiophenecarboxylic acid.
Metabolic pathway
The hydrolytic degradation of thifensulfuron methyl is pH dependent and, in alkaline condition, specifically yields the corresponding free acid. Primary degradation cleaves the sulfonylurea moiety to give two typical hydrolyzed products, sulfonamide and aminotriazine analogs, derived from thifensulfuron methyl in acidic and neutral conditions. Hydrolysis of the ester linkage proceeds in mammals, plants, soils, and also chemical hydrolysis, and opening of the triazine ring occurs to yield the acetyltriuret analog identified. On the other hand, by hydrolysis, O- demethylated thifensulfuron methyl undergoes opening of the triazine ring to give the corresponding acetyltriuret analog. Under photolytic conditions, methyl 3-(4-methoxy-6-methyl-1,3,5-triazin-2- yl)aminothiophene-2-carboxylate is identified.
