Use

Bensulfuron methyl is metabolized by mammals and birds and the major metabolites identified include mono-O-demethylated and 5-hydroxylated bensulfuron methyl and 5-hydroxy-2-amino-3,5- dimethoxypyrimidine. As bird metabolites, cleavage of the pyrimidine ring of bensulfuron methyl is observed which results in two pyrimidine ring-opening metabolites. In rice plants, bensulfuron methyl undergoes rapid O-demethylation at one of the methoxy groups on the pyrimidine ring which will proceed through hydroxylation at the methyl group. Alcoholysis and hydrolysis of bensulfuron methyl (H1) involve mainly the breakdown of the urea moiety which leads to several degradation products, some of which are also identified as metabolites in mammals and plants.
