APPLICATIONS

metsulfuron-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 systemic herbicide absorbed through the roots and foliage and translocated to the apex of the plants. Symptoms appear within days with death within 2-4 weeks. Uses Controls a wide range of grass and broad-leaved weeds in wheat, barley, rice, oats and triticale by post-emergence application, at 4-8 g/ha. Formulation types WG.

Application

It is a residual sulfonylurea compound used as a selective pre- and postemergence herbicide for broadleaf weeds and some annual grasses. It is a systemic compound with foliar and soil activity and it works rapidly after it is taken up by the plant. Its mode of action is by inhibiting cell division in the shoots and roots of the plant, and it is biologically active at low use rates.
