Abstract
The invention provides a herbicidal composition for the post-emergence selective control of grasses and weeds in cereals, such as wheat and barley. The composition contains two active components, one of which is N-(3-trifluoromethyl-1,2,4-thiadiazolyl-5)-N'-methyl-N'-methoxy urea and the other is a dichloropyridyloxy-.alpha.-phenoxypropionic acid derivative of the formula ##STR1## wherein X is oxygen or sulfur and R is hydrogen, a cation, a lower alkyl, alkenyl or alkynyl radical. The invention also provides a post-emergence method of selectively controlling grasses and weeds in crops of cereals, such as wheat and barley, which comprises the use of this composition. In particular wild oat species are selectively controlled.
