Abstract

Sequential application of cycloate (S-ethyl N-ethylthiocyclohexanecarbamate) at 3.4 kg/ha, phenmedipham (methyl m-hydroxycarbanilate m-methylcarbanilate) at 1.1 kg/ha, and trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) at 0.6 or 0.8 kg/ha, plus certain mechanical measures, controlled weeds during all periods of the growing season without significant injury to sugarbeets (Beta vulgaris L.). Early-season weed control was complete enough that the new selective mechanical thinners could have replaced labor for thinning. The additional labor required to bring the crop to harvest free of weeds was limited to one late-season hoeing, which required less than 10% of the total labor required in traditional weed control schedules without herbicides.
