China herbicides Ethofumesate manufacturer exporter and Supplier
Common name：Ethofumesate (BSI, E-ISO, (m) F-ISO, ANSI, WSSA)
IUPAC name(?-2-ethoxy-2,3-dihydro-3,3-dimethylbenzofuran-5-yl methanesulfonate
Chemical Abstracts name(?-2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate
PHYSICAL CHEMISTRY
FormWhite, crystalline solid; (tech. is a light brown crystalline solid; mild aromatic odour). SolubilityIn water 50 mg/l (25 ºC). In acetone, dichloromethane, dimethyl sulfoxide, ethyl acetate >600, toluene, p-xylene 300-600, methanol 120-150, ethanol 60-75, isopropanol 25-30, hexane 4.67 (all in g/l, 25 ºC).
StabilityStable to hydrolysis in water at pH 7 and 9.
BiochemistryInhibits lipid synthesis (not ACCase inhibition). Mode of actionSelective systemic herbicide, absorbed by the emerging shoots (grasses) and roots (broad-leaved plants), with translocation to the foliage. Not readily absorbed by leaves after the plant has generated a mature cuticle. Inhibits the growth of meristems, retards cellular division, and limits formation of waxy cuticle. UsesUsed pre- and/or post-emergence in sugar and other beet crops, turf, ryegrass and the other pasture grasses, at 0.3-2.0 kg/ha. It is effective in controlling a wide range of important grasses and broad-leaved weeds, with a good persistence of activity in the soil. In beet crops, 1.0-2.0 kg/ha can be used, but ethofumesate is normally recommended at 0.2-2.0 kg/ha in tank-mixtures or co-formulations with other residual or contact herbicides for use in beet. A high degree of tolerance is also shown by strawberries, sunflowers, Phaseolus beans and tobacco, depending on the time of application.
