74223-64-6 Metsulfuron Methyl herbicide for broadleaf weeds , annual grasses

Description:

Metsulfuron-methyl is a residual sulfonylurea compound used as a selective pre- and postemerg

ence herbicide for broadleaf weeds and some annual grasses. It is a systemic compound with fo

liar and soil activity, and it works rapidly after it is taken up by the plant. Its mode of action is by i

nhibiting cell division in the shoots and roots of the plant, and it is biologically active at low use ra

tes. The most common uses of metsulfuron-methyl include wheat, barley, rye, and pastures. It c

an be used with other foliar herbicides, and is typically applied on cereals at 0.004 - 0.007 pound

s active ingredient/acre, and on non-crop areas at 0.005-0.160 pounds active ingredient/acre. It i

s commercially available in the form of dry flowable formulations. Because it has residual activity

in soils, it is necessary to allow ample time for the chemical to break down before planting certain

crops (22 months for sunflowers, flax, corn, or safflower, and 10 months before planting sorghum).

It should not be used on ryegrass or on pastures containing alfalfa or clovers.
