Bensulfuron methyl is a systemic sulfonylurea herbicide for the pre- and post-emergence control of annual and perennial broad-leaved and sedge weeds in rice.

danyang, China (prHWY.com) March 1, 2013 - Bensulfuron methyl is a systemic sulfonylurea herbicide for the pre- and post-emergence control of annual and perennial broad-leaved and sedge weeds in rice.

The metabolic pathways of bensulfuron methyl in plants, soil, and animals are similar. Primary metabolic pathways include O-demethylation of the methoxypyrimidine moiety and cleavage of the sulfonylurea linkage.Minor metabolic pathways include the hydrolysis of the bensulfuron methyl ester to bensulfuron and hydroxylation of the pyrimidine ring.

NOMENCLATURE
bensulfuron methyl
Common name bensulfuron-methyl
IUPAC name methyl a-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-o-toluate
Chemical Abstracts name methyl 2-[[[[[(4,6-dimethoxypyrimidin-2-yl)-amino]carbonyl]amino] sulfonyl]methyl]benzoate
CAS RN [83055-99-6] EEC no. 401-340-6 (ELINCS) Development codes DPX-F5384 (DuPont)
APPLICATIONS
bensulfuron methyl
Biochemistry Branched chain amino acid synthesis (ALS or AHAS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. Selectivity is due to rapid metabolism in the crop. Metabolic basis of selectivity reviewed. Mode of action Selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation to the meristematic tissues. Uses Selective pre- and post-emergence control of annual and perennial weeds and sedges (e.g. Butomus umbellatus, Scirpus maritimus, Scirpus mucronatus, Alisma plantago-aquatica, Sparganium erectum, Cyperus spp., Typha spp., etc.) in flooded or wetland rice, at 46-60 g/ha.
