Toxicity
Oral: Acute oral LD50 for rats and mice >5000 mg/kg.
Skin and eye: Acute percutaneous LD50 for rats >2000 mg/kg. Not a skin or eye irritant. Not a skin sensitiser.
Inhalation: LC50 (4 h) for rats >3.97 mg/l air.
Application
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.
