Abstract

The invention discloses a bactericidal composition containing pydiflumetofen and penthiopyrad. The active ingredients of the bactericidal composition are pydiflumetofen and penthiopyrad, and the weight ratio of pydiflumetofen to penthiopyrad is (2.5-40): (5-80). Meanwhile, the invention also discloses application of the bactericidal composition in preventing and treating southern blight and powdery mildew of mangoes. According to the sterilization composition, the action range of the pydiflumetofen and the penthiopyrad is expanded, the application amount of the pydiflumetofen and the penthiopyrad is reduced and the effect is still kept good. Secondly, even if a single compound becomes completely invalid at a low application amount, the combination of the pydiflumetofen and the penthiopyradstill achieves a high plant pathogen control effect. The spectrum of plant pathogens capable of being prevented and treated is expanded and the use safety is improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicidal composition containing flufenpyroxycin and penthiopyrad and its application. Background technique [0002] Mango powdery mildew is a fungal disease that is prone to occur during mango planting. Its main symptom is that some scattered white powdery small plaques appear on the damaged organs, and then gradually expand and combine with each other to form a white powdery mold layer. The tissue under the mold layer gradually turns brown and necrotic. Mango canker sore is a kind of sclerotinia seedling blight, and this disease causes harm to mango seedlings, and after seedlings infect, stem base and root epidermis become brown and rot, wilting symptoms appear in leaves, and the whole plant dies at last. These two diseases are the most widespread and most serious diseases of mango, which have seriously affected the development of this tropical and subtropical fruit of m...
