Herbicidal compositions 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,

Synergistic herbicidal composition comprising triazine herbicides and

Herbicidal compositions comprising as active ingredients a triazine derivative represented by general formula [I]: ##STR1## and compound represented by general formula [II]: ##STR2## By synergistic effects of active ingredients, the herbicidal compositions show a high herbicidal effect at low dosage and have such a wide range of herbicidal spectrum that the compositions exhibit their high herbicidal effect not only against broad-leaved weeds but also against Gramineae weeds, etc. The compositions have flexibility of treatment to exhibit effectiveness as compared to known herbicides for field crops and crops are free from injury.
