Synergistic bactericidal composition containing fluxapyroxad and isoprothiolane

Abstract

The invention provides a synergistic bactericidal composition containing fluxapyroxad and isoprothiolane and belongs to the technical field of compound pesticides. According to the synergistic bactericidal composition, fluxapyroxad and isoprothiolane are taken as major active ingredients and compounded with known auxiliaries and an excipient into a pesticide in any allowable form; the synergistic bactericidal composition can be applied to preparing pesticides for preventing and treating resistant fungal diseases of cereal, fruit trees and vegetable crops; the application range of the synergistic bactericidal composition is widened and the prevention and treatment spectrum of the synergistic bactericidal composition is expanded; the synergistic bactericidal composition has excellent prevention and treatment effects on fungal diseases of ascomycetes, basidiomycetes, imperfect fungi and oomycetes, and especially has an obvious synergistic effect on resistant fungal diseases such as powdery mildew, gray mold, stalk break, rot, rust, glume blight, net blotch, downy mildew, rice blast and damping off, and therefore, the prevention and treatment effects are obviously improved. The activity of the synergistic bactericidal composition is greater than that of a single active ingredient; besides, the production and use costs are reduced, and the labor and pesticide costs for prevention and treatment are reduced.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides and relates to the production technology of bactericidal compositions. Background technique [0002] Flupyroxyroxamide is a pyrazole amide fungicide, a succinate dehydrogenase inhibitor, both for prevention and treatment. It can inhibit fungal respiration, inhibit spore germination, germination tube elongation, hyphal growth and sporulation. Can be used to control and suppress a variety of fungal diseases on a variety of crops. However, the cost of single-dose flufenapyroxamide alone is relatively high at present. [0003] Daobunling is an organic sulfur fungicide with high efficiency, low toxicity and low residue, which is used to control rice neck blast, rice leaf blast, and rice seedling blast. It is a high-efficiency systemic fungicide and a special agent for controlling rice blast. It has preventive and therapeutic effects on rice blast, can be absorbed by various parts of ric...

AI Technical Summary

Problems solved by technology

[0004] 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 one 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 plant disease control is facing a major challenge
