Sterilization composition containing prothioconazole and difenoconazole and application thereof

Abstract

The invention discloses a sterilization composition containing prothioconazole and difenoconazole and an application thereof. The sterilization composition takes prothioconazole and difenoconazole as main effective ingredients. The sterilization composition can be applied to prevention and treatment of diseases of grains, fruit trees and vegetables, has a relatively high synergetic effect, can be used for overcoming and retarding drug resistance of bacteria with high sterilization speed and long duration, and reducing application cost, and has a prevention and treatment effect remarkably superior to that of a single preparation. The sterilization composition can be used for preventing and treating fungous diseases of crops, especially powdery mildew, banded sclerotial blight, fusarium wilt, leaf spot, rust disease, sclerotinia sclerotiorum, net blotch, scald, botrytis, black spot, brown blotch, black shank, scab, sphaceloma ampelinum, white rot, alternaria leaf spot, brown patch and gibberellic disease, and has an effect better than that of a single preparation.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with prothioconazole and difenoconazole 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 of the precursor of sterol in fungi—lanosterol or 24-methylene dihydromimaudine at the 14-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 results show that pro...

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
