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 fenpyrazamine and simeconazole-containing bactericidal composition and application thereof. The bactericidal composition comprises fenpyrazamine and simeconazole as main effective components in the mass 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, especially can be used to control leaf spot disease, gray mold, root rot, stalk break and other fungus diseases, 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.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fenflufen and silfluazole as main active ingredients and its application. Background technique [0002] Fenpyrazamine is a heterocyclic fungicide based on pyridine, molecular formula: C 17 h 21 N 3 o 2 S, chemical name: 1-[(2-propenylthio)formyl]-2-isopropyl-4-(2-methylphenyl)-5-amino-1H-pyrazol-3-one. [0003] Pathogen that inhibits the mechanism of action of the ergosterol biosynthetic pathway, showing inhibition of mycelial growth and spore germination and pollen tube growth. It is mainly used for the control of botrytis and is used for cucumbers, grapes, citrus, potatoes, peppers, eggplants, ornamental plants, etc. [0004] Flusilazole (flusilazole), molecular formula: C 16 h 15 f 2 N 3 Si, chemical name: bis(4-fluorophenyl)methyl(1H-1,2,4-azol-1-ylmethylene)silane. Structural formula: [0005] [0006] Silfluazol...
