Bactericidal composition containing prothioconazole and validamycin and application thereof

Abstract

The invention discloses a bactericidal composition containing prothioconazole and validamycin and application thereof. The bactericidal composition uses the prothioconazole and validamycin as main effective components, wherein the weight ratio of the prothioconazole to the validamycin is (1-90):(1-90). The bactericidal composition can be used for preventing and treating diseases on cereals, fruit trees and vegetable crops, has higher synergic effect, overcomes and postpones the drug resistance of pathogenic bacteria, has the advantages of high bactericidal speed and long duration time, lowers the use cost, and has obviously better preventing and treating effects than a single agent. The bactericidal composition can be used for preventing and treating fungus diseases on crops, especially can be used for preventing and treating powdery mildew, rust, gray mold, black spot, brown spot, hollow stald rot, sheath blight and other fungus diseases, and has better effect than a single agent.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with prothioconazole and jinggangmycin as main active ingredients and its application. Background technique [0002] Prothioconazole is a new 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 at the 14th position of lanosterol or 24-methylene dihydromimaudine, the precursor of sterol in fungi. the demethylation inhibitors. 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 results show that prothioconazol...

Problems solved by technology

[0008] At present, with the change of planting structure, the degree and number of diseases of melons, fruits, vegetables, and cereal crops have increased, and it is more difficult to prevent and control objectively; Under pressure, the resistance of pathogenic bacteria has increased year by year, and the control effect of a single agent has been greatly reduced; third, the current introduction of new pesticide varieties has dropped significantly, and there is a lack of new target agents; fourth, due to increasingly stringent environmental protection requirements, some Products are restricted in use, resulting in less selective medication
