A kind of bactericidal composition containing prothioconazole and fluoxamid and its application

Abstract

Disclosed are a prothioconazole and fluopicolide containing sterilization composition and uses thereof. The sterilization composition uses prothioconazole and fluopicolide as main active components. The sterilization composition can be used for preventing and curing diseases of cereal, fruit trees and vegetables, has a relatively high synergistic effect, overcomes and delays drug resistance of pathogens, has a fast sterilization speed and a long persistent period, reduces the application cost, and has an obviously more excellent prevention and cure effect than the prevention and cure effect when prothioconazole and fluopicolide are separately used. The present invention can be used for preventing and curing fungal diseases on crops, especially a powdery mildew disease, a sheath blight disease, a wilt disease, a leaf spot disease, a rust disease, a rhizoctonia disease, a net blotch disease, a leaf blotch disease, a gray mold disease, a black spot disease, a brown spot disease, a black shank disease, a rice blast disease and a phytophthora disease, and has a better effect than the effect when prothioconazole and fluopicolide are separately used.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with prothioconazole and fluoxamid as main active ingredients and its application. Background technique: [0002] Prothioconazole (Prothioconazole), is a novel broad-spectrum triazolethione fungicide developed by Bayer, chemical name: 2-(2-(1-chlorocyclopropyl)-3-(2-chlorophenyl )-2-hydroxypropyl-1-2-dihydro-3-1,2,4-triazole-3-thio, molecular formula: C 14 h 15 Cl 2 N 3 OS. The structural formula is as follows: [0003] [0004] The mechanism of action of prothioconazole is to inhibit the demethylation of the precursor of sterol in fungi - lanosterol or 24-methylene dihydromimaudine at the l4 position, that is, demethylation inhibitors (DMIs) . Not only has good systemic activity, excellent protection, treatment and eradication activity, but also has a long lasting effect. Through a large number of field efficacy tests, the r...

AI Technical Summary

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
