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 sterilization composition with isopyrazam and orysastrobin and application of the sterilization composition. The sterilization composition comprises isopyrazam and orysastrobin as main effective components, wherein the mass ratio of isopyrazam to orysastrobin is (1-70): (1-50). The sterilization composition is capable of preventing and treating diseases of cereals, fruit trees and vegetables, particularly fungal diseases such as anthracnose, downy mildew, gray mold, powdery mildew, damping off diseases, banded sclerotial blight and rice blast, has relatively high synergism, is capable of overcoming and retarding drug resistance of pathogenic bacteria, and is rapid in sterilization speed, long in effect lasting time and low in application cost, and the prevention and treatment effects of the sterilization composition are remarkably superior to those of single chemicals.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with pyraclostrobin and orysastrobin as main active ingredients and its application. Background technique [0002] Isopyrazam, molecular formula: C 20 h 23 f 2 N 3O , Chemical name: 3-difluoromethyl-1-methyl-N-[1,2,3,-tetrahydro=9-(1-methylethyl)-1,4-methanonaphthalen-5-yl] -1H-pyrazole-4-carboxamide. [0003] Pyrafenapyramide is a pyrazole fungicide, a new type of systemic fungicide with spectrum, protective and therapeutic activities. [0004] Orysastrobin, molecular formula: C 18 h 25 N 5 o 5 , chemical name: (2E)-2-(methoxyimino)-2-{2-[(3E,5E,6E)-S-(methoxyimino)-4,6-dimethyl-2, 8-dioxa-3,7-dioxanon-3,6-dien-1-yl]phenyl}-N-methylacetamide. Structural formula: [0005] [0006] Orysastrobin is a methoxyacrylate fungicide, which is mainly used to control rice blast and sheath blight in rice. [0007] At present, the pr...
