Methyl 2-[4-methoxy-6-methyl-1,3,5-triazin-2-yl(methyl)carbamoylsulfamoyl]benzoate
Chemical class: Herbicide
Molecular formula: C16H17N6O6S
CAS NO.: 101200-48-0
Properties:
Off-white powder, with a slight pungent odour. M.p.
142°C. V.p. 5.2×10⁻⁶ mPa (25°C). S.g./density 1.46 (20°C). In water 0.05 (pH 5), 2.04 (pH 7), 18.3 (pH 9) (all in g/L, 20°C). In acetone 3.91×10⁴, acetonitrile 4.64×10⁴, ethyl acetate 1.63×10⁴, n-heptane 20.8, methanol 2.59×10³ (all in mg/L, 20°C).
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 occurring after 10-25 days under optimal conditions.
Usage:
Post-emergence control of broad-leaved weeds in cereal crops, including wheat, barley, oats, rye and triticale, at 7.5-30 g/ha.
Normal Formulations:
95% Tech, 75% WDG/DF/WP
