Abstract
A herbicidal composition comprising, as active ingredients, a triazine compound of the formula (I): ##STR1## wherein Z is oxygen, sulfur or ##STR2## X.sup.2 is methyl or fluorine, n is 0 to 2, R.sup.1 is hydrogen or methyl, and X.sup.1 is fluorine or chlorine, and a sulfonylurea herbicide of the formula (II): ##STR3## wherein the ratio of the triazine compound to the sulfonylurea herbicide is 100/1 to 1/10 by weight. The herbicidal composition provides a synergistic herbicidal effect against a wide spectrum of weeds, without causing crop injury.
