Sterilization composition containing prothioconazole and trifloxystrobin and application thereof

Abstract

The invention discloses a sterilization composition containing prothioconazole and trifloxystrobin and an application thereof. The sterilization composition takes prothioconazole and trifloxystrobin 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, rice blast and apple scab, and has an effect better than that of a single preparation.

Description

Technical areas: [0001] The present invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with prothioconazole and trifloxystrobin 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 sterol precursor in fungi - lanosterol or the 14-position of 24-methylenedihydropentane, that is, demethylation inhibitors (DMIs). . It not only has good systemic activity, but also has excellent protection, treatment and eradication activities, and has a long lasting effect. Through a large number of field efficacy tests, the...

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
