Abstract
Undesired vegetation, including crabgrass, Johnson grass and pigweed are effectively controlled in cotton, corn and peanuts in the warm temperate zones by application of an effective amount of 1,3-dimethyl-1-(5-tert.butyl-1,3,4-thiadiazol-2-yl)urea or the corresponding 1-ethyl-3-methyl compound to the locus of the weeds. A particularly desirable procedure is the use of one of the new herbicides in combination with alachlor to give very broad spectrum weed control, including such noxious weeds as nutsedge.
