Problems solved by technology

[0007] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge

Abstract

The invention discloses a bactericidal composition containing fluxapyroxad and famoxadone and application thereof. The bactericidal composition is mainly composed of fluxapyroxad and famoxadone in the weight ratio of 1-70:1-50. The bactericidal composition can be applied to the prevention and control of diseases of cereals, fruit trees and vegetables, has high synergistic effect, can overcome and delay drug resistant of bacteria, is fast in sterilization speed and long in duration, and reduces the application cost, and the control effect is obviously better than that of a single agent. The bactericidal composition can be used for prevention and treatment of fungal diseases of crops, especially can be used to control sheath blight, gray mold, powdery mildew, rust, glume blight, net blotch, downy mildew, late blight and other fungus diseases, and the effect is better than that of a single agent.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with flufenapyroxad and oxaflucondone as main active ingredients and its application. Background technique [0002] Fluxapyroxad (fluxapyroxad), chemical formula: C 18 h 12 f 5 N 3 O, chemical name: 3-(difluoromethyl)-1-methyl-N-(3',4',5'-trifluorobiphenyl-2-yl)pyrazole-4-carboxamide. [0003] Flufenapyramide belongs to the formamide fungicides and is a succinate dehydrogenase inhibitor. It is a broad-spectrum fungicide with excellent therapeutic and systemic activity. It is effective against various crop sheath blight and gray mold All have good control effects. [0004] Famoxadone, molecular formula: C 22 h 18 N 2 o 4 , chemical name: 33-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazoline-2,4-dione. Structural formula: [0005] [0006] Falfafen is a new type of high-efficiency and broad-spectrum fungicide. It is suitable...
