Molecular formula

C13H18O5S

packing

application

Biochemistry

Inhibits lipid synthesis (not ACCase inhibition). 

Mode of action

Selective 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. 

Uses

Used 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.

Phytotoxicity

Onions, peas, beans, carrots, and cotton are tolerant to some extent.  Formulation types

EC; SC.
