To provide a herbicidal composition which is highly safe to crop plants and which is capable of controlling weeds problematic in e.g. paddy fields, upland fields and non-agricultural fields over a wide range of from preemergence to postemergence. A herbicidal composition comprising the following Component A which is at least one compound selected from the group consisting of isoxazoline derivatives of the formula I and their salts, and the following Component B, as active ingredients: wherein each of R<1 >and R<2 >which are independent of each other, is a hydrogen atom, a C1-C10 alkyl group, a C3-C8 cycloalkyl group or a C3-C8 cycloalkyl C1-C3 alkyl group, each of R<3 >and R<4 >which are independent of each other, is a hydrogen atom, a C1-C10 alkyl group, a C3-C8 cycloalkyl group, or R<1>, R<2>, R<3 >and R<4 >may form a 5- to 8-membered ring together with the carbon atoms to which they are bonded, each of R<5 >and R<6 >which are independent of each other, is a hydrogen atom or a C1-C10 alkyl group, Y is a 5- or 6-membered aromatic heterocyclic or aromatic condensed heterocyclic group having an optional hetero atom selected from the group consisting of a nitrogen atom, an oxygen atom and a sulfur atom, Component B: Imazaquin, diuron, sulfentrazone, sulcotrione, norflurazon, clomazone, dimethenamid-P, prosulfocarb, isoproturon, trifluralin or triallate. |
