Compound composition containing bixafen and mefentrifluconazole and application of compound composition

Abstract

The invention discloses a compound composition containing bixafen and mefentrifluconazole. The compound composition is prepared from the bixafen and the mefentrifluconazole, the composition takes thebixafen and the mefentrifluconazole as effective components, and the weight ratio of the bixafen to the mefentrifluconazole is 1: 80-80: 1. The sterilization composition can be applied to prevention and treatment of diseases of cereal crops, vegetables and fruit trees, has a relatively high synergistic effect, overcomes and delays the drug resistance of germs, is high in sterilization speed, widein prevention and treatment range and long in lasting period, reduces the application cost, and has a prevention and treatment effect obviously superior to that of a single agent.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition containing bixafen and chloroflufenazole and its application. Background technique [0002] Bixafen (Bixafen), chemical name: N-(3′,4′-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1-methylpyrazole -4-formamide, molecular formula: C 18 h 12 Cl 2 f 3 N 3 O, the chemical structural formula is as follows: [0003] [0004] Bixafen is a pyrazole amide fungicide developed by Bayer Crop Science, and it is a new type of succinate dehydrogenase inhibitor (SDHI) fungicide. Bixafen is a systemic fungicide with a novel mechanism of action and a broad bactericidal spectrum, and is specially used for foliar sprays. It can effectively control important diseases caused by Ascomycetes, Basidiomycetes and Deuteromycetes on cereal crops. [0005] Mefentrifluconazole, (2RS)-2-[4-(4-chlorophenoxy)-α,α,α-trifluoro-o-tolyl]-1-(1H-1,2, 4-triazol-1-yl) propan-2...

AI Technical Summary

Problems solved by technology

[0008] With the continuous changes in the planting structure and the large-scale use of pesticides in agricultural production, the incidence and number of diseases of melons, fruits, vegetables, and cereals have increased, increasing the difficulty of prevention and control

In addition, large areas and large doses of medicines also increase the resistance of pathogenic bacteria. Once drug resistance occurs in a large area, it will be difficult to control

At present, the slowdown in the introduction of new types of pesticides and the continuous improvement of safety and environmental protection requirements have led to narrower selection of pesticides
