摘要

A herbicidal composition containing as active ingredients the following two components: (A) at least one of 1,3-oxazin-4-one derivatives represented by general formula (I), wherein R is a methyl or an ethyl group, Y is a halogen atom, a lower haloalkyl or a lower haloalkoxy group, and n is 0, 1, 2 or 3, and (B) at least one compound selected from certain known herbicides. It is possible, by use of this composition, to completely control annual gramineous weeds, annual broad-leaved weeds and perennial weeds, without causing any phytotoxicity on agriculturally important crops at a low dose of the active ingredients.
