CAS:101200-48-0 Tribenuron-methyl Methyl 2-[[[[(4-methoxy-6-methyl-1,3,5,triazin-2-yl)methylamino]carbonyl]amino]sulfonyl]benzoate
ctive ingredient |
Tribenuron-methyl |
||
Chemical name |
methyl 2-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)methylamino]carbonyl]amino]sulfonyl]benzoate |
||
Classification |
Herbicide / Agrochemical |
||
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 10-25 days under optimal conditions. Uses barley, oats, rye and triticale, at 7.5-30 g/ha. |
||
Usage |
Post-emergence control of broad-leaved weeds in cereal crops, including wheat, barley,
oats, rye and triticale, at 7.5-30 g/ha. |
