Abstract

The invention discloses a sterilization composition containing prothioconazole and azoxystrobin and an application thereof. The sterilization composition takes prothioconazole and azoxystrobin 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, glume blight, net blotch, downy mildew and rice blast, 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 azoxystrobin 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 l4 position of the precursor of sterol in fungi - lanosterol or 24-methylene dihydromimaudine, namely 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...
