Ethofumesate Biochemistry pre or post-emergence systemic Selective Herbicide

Ethofumesate Biochemistry pre or post-emergence systemic Selective Herbicide

• 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

1. FormWhite, crystalline solid; (tech. is a light brown crystalline solid; mild aromatic odour).
2. Solubility: In 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).
3. Stability:Stable to hydrolysis in water at pH 7 and 9.

• Biochemistry:Inhibits lipid synthesis (not ACCase inhibition).

• Mode of action

1. Selective systemic herbicide, absorbed by the emerging shoots (grasses) and roots (broad-leaved plants), with translocation to the foliage.
2. Not readily absorbed by leaves after the plant has generated a mature cuticle.
3. Inhibits the growth of meristems, retards cellular division, and limits formation of waxy cuticle.

• Uses:

1. Used pre- and/or post-emergence in sugar and other beet crops, turf, ryegrass and the other pasture grasses,
2. at 0.3-2.0 kg/ha. It is effective in controlling a wide range of important grasses and broad-leaved weeds,
3. with a good persistence of activity in the soil. In beet crops, 1.0-2.0 kg/ha can be used,
4. 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.
5. A high degree of tolerance is also shown by strawberries, sunflowers, Phaseolus beans and tobacco, depending on the time of application.
