Fungicidal composition and method for controlling plant diseases

摘要

To provide a fungicidal composition having stable and high fungicidal effects against cultivated crops infected with plant diseases resulting from plant diseases.;A fungicidal composition containing, as active ingredients, (a) a benzoylpyridine derivative represented by the formula (I) or its salt:;
wherein when A is —N═, B is —CX4═; when A is —CH═, B is —N═; each of X1 and X2 which are independent of each other, is a halogen atom, an alkoxy group, a hydroxyl group, an alkyl group, a CF3 group or an alkylthio group; X3 is a hydrogen atom, a halogen atom, an alkoxy group, an alkyl group, a CF3 group or an alkylthio group; X4 is a hydrogen atom, a halogen atom, an alkoxy group, an alkyl group, a CF3 group or an alkylthio group; R1 is an alkyl group; R2′ is an alkoxy group; p is 0, 1 or 2; and each of R2″ and R2′″ is an alkoxy group, and (b) at least one additional fungicide.
