Problems solved by technology

[0008] 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 bixafen and propiconazole and an application thereof. The bactericidal composition uses bixafen and propiconazole as main active ingredients, wherein the mass ratio of bixafen to propiconazole is 1-70:1-50. The bactericidal composition can be applied to the prevention and treatment of cereals, fruit trees, and vegetable diseases, has a high synergistic effect, overcomes and delays the drug resistance of pathogens, has fast sterilization speed, long-lasting effect, reduces application costs, and has good control effect. Significantly better than its single dose use. The present invention can be used for the prevention and treatment of fungi on crops, especially for the prevention and treatment of fungal diseases such as leaf spot, leaf rust, powdery mildew, net spot, root rot, head blight and smut, and the effect is significantly better than that of Use as a single dose.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its use, in particular to a bactericidal composition with bixafen and propiconazole as main active ingredients and its application. Background technique [0002] Bixafen (Bixafen), chemical formula: C 18 H 12 C l2 F 3 N 3 O, chemical name: N-(3',4'-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1-methylpyrazole-4-carboxamide. Structural formula: [0003] [0004] Bixafen is a pyrazole fungicide, a new type of systemic fungicide with broad-spectrum, protective and therapeutic activities. [0005] Tebuconazole, molecular formula: C 16 H 22 ClN 3 O, chemical name: 3'-chloro-4,4'-dimethyl-1,2,3-thiadiazole-5-carboxanilide. Structural formula: [0006] [0007] Propiconazole is a triazole bactericidal pesticide and a sterol demethylation inhibitor. It is a high-efficiency bactericide used for seed treatment or foliar spraying of important economic crops. It can effectively control a variety of rust and po...
