Toxicity: |
LD50
is > 5,000 mg/kg in rats. It has low dermal toxicity in tests with
rabbits, with an LD50 > 2,000 mg/kg and low inhalation toxicity in
rats, with a median lethal concentration in air of greater than 5
mg/liter air. Moderate but reversible eye irritation has been seen
in rabbits, and mild skin irritation has been observed in guinea
pigs.

Application: |
Metsulfuron-methyl 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.The
most common uses of metsulfuron-methyl include wheat, barley, rye,
and pastures
