Antifungal composition containing tebuconazole and pyrimidine compound

Abstract

The invention discloses an antifungal composition which comprises two active components A and B, wherein the component A is tebuconazole; the component B is pyrimethanil B1, cyprodinil B2, mepanipyrim B3, ethirimol B4, dimethirimol B5, bupirimate B6, difulmetorim B7, nuarimol B8 or fenarimol B9, or salts thereof. The weight ratio of the component A to the component B is (1:50) to (50:1), and the active components account for 0.1-95% of the weight of the composition. The antifungal composition disclosed by the invention is particularly suitable for preventing and controlling diseases such as botrytis, powdery mildew, venturia inaequalis and the like caused by various kinds of plant pathogenic fungi.
