A kind of bactericidal composition containing flupyroxad and silfluazole and its application

Abstract

The invention discloses a sterilizing composition containing fluxapyroxad and simeconazole and application of the sterilizing composition. The sterilizing composition uses the fluxapyroxad and the simeconazole as the main effective components, wherein the mass ratio of the fluxapyroxad to the simeconazole is (1-70):(1-50). The sterilizing composition has the advantages that the sterilizing composition can be used for preventing and treating diseases of cereal crops, fruit trees and vegetables, has a high synergic effect and is capable of overcoming and delaying the insecticide resistance of pathogenic bacteria, fast in sterilizing, lasting in effect and capable of lowering application cost, and the preventing and treating effect of the sterilizing composition is evidently better than that of the fluxapyroxad or the simeconazole used independently; the sterilizing composition can be used for preventing and treating fungous diseases of the crops and especially used for preventing and treating the fungous diseases such as powdery mildew, venturia inaequalis, rust disease, damping-off, sheath blight and gray mold, and the preventing and treating effect of the sterilizing composition is evidently better than that of the fluxapyroxad or the simeconazole used independently.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with flufenapyramide and silfluazole 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] Simeconazole (simeconazole), molecular formula: C 14 h 2 0F N 3 O Si, chemical name: (RS)-2-(4-fluorophenyl)-1-(1H-1,2,4-1 trioxane-1-yl)-3-trimethylsilylpropane-2 -alcohol. Structural formula: [0005] [0006] Silfluazole is a silicon-containing triazole...

AI Technical Summary

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
