Synergistic bactericidal composition

Abstract

The invention relates to a synergistic bactericidal composition and belongs to the technical field of complex pesticides. According to the synergistic bactericidal composition provided by the invention, fluxapyroxad and octyl bacterial amine are taken as main active ingredients to be compounded with known additives and excipients to form any allowable form, such as water dispersible granules, wet seed dressing agents, emulsifiable concentrate, wettable powder, suspension concentrate, oil formulation, suspoemulsion, coating agents of suspension concentrate, emulsion in water or microemulsion. The synergistic bactericidal composition provided by the invention has a significant effect when being applied to the preparation of medicaments for controlling resistant plant fungal diseases of cereals, fruit tress, vegetables and other crops, when being applied to the preparation of bactericidal medicaments for controlling powdery mildew, gray mold, sclerotiose, rot, rust, glume blight, net blotch, downy mildew, rice blast and sheath blight, and particularly when being applied to the preparation of bactericidal medicaments for controlling rice blast and powdery mildew of cucumbers.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides and relates to a bactericidal composition. 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] Cycloprodil kills bacteria (viruses) by destroying the cell membranes of various pathogens, coagulating proteins, preventing respiration and enzyme activities. The drug has certain systemic and osmotic effects, and has significant killing and inhibiting effects on various plant fungi, bacteria and viruses that cause crop diseases. Because the time limit for controlling major rice diseases w...

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
