| General info | Categories: Herbicides |
| Common name: bensulfuron-methyl |
| ChemicalAbstractsname:methyl 2-(4,6-dimethoxypyrimidin-2-yl)- amino]carbonyl]amino]sulfonyl]methyl]benzoate |
| CAS No: 83055-99-6 |
| Properties | Composition: Tech. is 96%. |
| MW: 410.4; |
| MF: C16H18N4O7S; |
| Form: White to pale yellow, odourless solid. |
| M.p.: 185-188C; |
| V.p.: 2.8x10-9 mPa (25C). |
| KOW: logP = 2.45 (pH 1.5), 0.62 (pH 7) (both at 30C). |
| Henry: 1.4x10-11 Pa m3 mol-1 |
| S.g./density: 1.41; |
| Solubility: In water 2.9 (pH 5), 12 (pH 6), 120 (pH 7), 1200 (pH 8) (all in mg/l, 25C). In 1.38, 5.38, 11.7, 1.66, >0.01, xylene 0.280 (all in g/l, 20C). |
| Stability: Aqueous solutions are most stable under slightly alkaline conditions (pH 8), and slowly degrade under acidic conditions; DT50 11 d (pH 5), 143 d (pH 7) (25C). |
| Applications | |
| Biochemistry: Branched chain amino acid synthesis (ALS or AHAS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. Selectivity is due to rapid metabolism in the crop. |
| Mode of action: Selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation to the meristematic tissues. |
| Uses: Selective pre- and post-emergence control of annual and perennial weeds and sedges (e.g. Butomus umbellatus, Scirpus maritimus, Scirpus mucronatus, Alisma plantago-aquatica, Sparganium erectum, Cyperus spp., Typha spp., etc.) in continuously flooded rice, at 30-100 g/ha. |
