    APPLICATIONS

    tribenuron-methyl

    Biochemistry Affects sensitive weeds through inhibition of the enzyme acetolactate synthase (ALS). Inhibition of ALS leads to the rapid cessation of cell division and subsequent growth processes in plants. Mode of action Selective, post-emergence herbicide, acting primarily through foliar uptake, with little or no soil activity. Symptoms of chlorosis appear in affected weeds in days with necrosis and death occuring after 10-25 days under optimal conditions. Uses Post-emergence control of broad-leaved weeds in cereal crops, including wheat, barley, oats, rye and triticale, at 7.5-30 g/ha. Formulation types TB; WG.
