Active ingredient

Common name:

tribenuron-methyl

Chemical name:

methyl 2-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)

methylamino]carbonyl]amino]sulfonyl]benzoate

CAS No:

101200-48-0

Molecular Formula:

C15H17N5O6S

Pesticide category:

Herbicide

Analysis method:

Product and residue analysis by hplc/ms/ms (Handbook of Residue Analytical Methods, pp 400-410).

Mode of Action:

Selective, post emergence herbicide, acting primarily through

foliar uptake, with little or no soil activity. Symptoms of

chlorosis appear in affected weeds in days with necrosis and death occuring after 10-25 days under optimal conditions.

Characteristics and Uses:

Post-emergence control of broad-leaved weeds in cereal crops,

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

Toxicity:

Oral: Acute oral LD50 for rats >5000 mg/kg.

Skin and eye: Acute percutaneous LD50 for rabbits >5000

mg/kg.

Non-irritating to skin and eyes (rabbits). Mildly sensitising to

skin (guinea pig maximisation test), but not likely to be a dermal sensitisation risk to humans.

Inhalation: LC50 (4 h) for rats >5.0 mg/l air.

Application

used in killing broad-leaf weeds, such as water mouseear chickwed, henbit, corn gromwell etc.
