Crops Cereal crops,

including wheat, barley, oats, rye and triticale, at 7.5-30 g/ha.

Controlling broad-leaved weeds

Tribenuron-Methyl is a kind of selective, systemic and transferring post-emergence herbicide.

Tribenuron-Methyl can be absorbed and transferred by the stems and leaves of weeds to

prevent from the division of cell and make the weeds die. Tribenuron-Methyl can be stable

in soil for 30-45days and has no harm to the succeeding crops.
