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 derives from rapid metabolism (demethylation of methoxy group) in the crop. Metabolic basis of selectivity in sulfonylureas reviewed (M. K. Koeppe & H. M. Brown, Agro-Food-Industry, 1995, 6, 9-14).
Application
Control of annual and perennial broad-leaved weeds and sedges, pre-or post-emergence in wet-sown and transplanted rice crops, at 15-30 g/ha.
