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 ethirimol and an application thereof. The bactericidal composition takes fluxapyroxad and ethirimol as main active ingredients, wherein the mass ratio of fluxapyroxad to ethirimol is (1-70) to (1-50). The bactericidal composition can be used for controlling cereal, fruit tree and vegetable diseases, has higher synergistic effects, has the effects of overcoming and delaying the drug resistance of germs, has a high bactericidal speed and a long lasting period, has the effect of reducing the application cost and has obviously better control effects than single agents. The bactericidal composition can be used for controlling fungal diseases on crops, especially fungal diseases, such as sheath blight, gray mold, powdery mildew, and the like, and has obviously better effects than single agents.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with flufenapyroxad and pyrimol 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] Ethirimol (ethirimol), molecular formula: C 11 h 19 N 3 O, chemical name: 5-butyl-2-ethylamino-4-hydroxy-6-methylpyrimidine. Structural formula: [0005] [0006] Acetrimol is a systemic fungicide that can control powdery mildew in cereals. When used as a seed ...
