Weed control using 3-(4-isopropylphenyl)-1,1-dimethylurea in combination with S-2,3,3-trichloroallyl diisopropylthiocarbamate.

摘要

The invention provides a method for the control of the growth of grass weeds and broad-leafed weeds by application of the herbicides 3-(4-isopropylphenyl)-1,1-dimethylurea (i.e. isoproturon) and S-2,3,3-trichloroallyl diisopropylthiocarbamate (i.e. triallate) in association, the ratios of isoproturon to triallate being 2.5:1 to 1:2.5 by weight, at the application rates of 1.0 to 2.5 kg per hectare each of isoproturon and triallate by pre- or post-emergence application.
