Трибенурон-метил APPLICATIONS
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 in the crop. Metabolic basis of selectivity in sulfonylureas reviewed (M. K. Koeppe & H. M. Brown, Agro-Food-Industry, 6, 9-14 (1995)). Mode of action Rapidly absorbed by foliage and roots and translocated throughout the plant. Susceptible plants cease growth almost immediately after post-emergence treatment and are killed in 7-21 days. Surfactants increase the activity of tribenuron-methyl on certain broad-leaved weeds. Uses Post-emergence control of broad-leaved weeds in spring and winter cereals, at 9-30 g/ha. Formulation types TB; WG.
