SPECIFICATION AND FORMULATION: *5TC, *5WG, *0WP PACKING:*5KG carton drum, or on the client&#**9;s requirement. APPLICATION: Branched chain amino acid synthesis (acetolactate synthase or ALS) inhibitor.Acts by inhibiting bilsynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant ***** absorbed by foliage and roots and translocated throughout the plant.Susceptible plants cease grough almost immediately after post-emergence treatment and are killed in ***1 days.Surfactants increase the activity of tribenuron-methyl on certain broad-leaved weeds.Post emergence control of b
