Abstract

The invention discloses a bactericidal composition and its application, the effective component comprises an ingredient A and an ingredient B. The ingredient A is metalaxyl-M, the ingredient B is selected from one of polyoxin, Ningnanmycin and validamycin. The invention has the advantages of high efficiency, safety and environmental protection. The bactericidal composition has synergistic effect which is characterized in that the product output can be raised, the cost can be reduced and the generation of drug resistance of germs can be delayed. The invention can be used for preventing and treating sheath blight, root rot, rice blast, corn northern and southern leaf blight, downy mildew, phytophthora blight, leaf spot, botrytis, alternaria leaf spot, anthracnose, ring spot, powdery mildew,black shank and late blight.

Description

technical field [0001] The invention relates to a bactericidal composition and its application. Background technique [0002] At present, in pest biochemical control, the problem of pest resistance is very serious. Diseases caused by Oomycetes are common in agricultural production and often cause heavy losses. As a fungicide with significant protective, therapeutic and eradicating effects, metalaxyl is widely used in the control of crop diseases and has good control effects. However, studies have shown that mefenaxyl has a high risk of resistance to greenhouse and greenhouse crop diseases. The compound composition with synergistic effect can reduce the risk of resistance to a certain extent, avoid the generation of resistance and delay the speed of resistance generation. [0003] Polyoxin produced in my country is a metabolite produced by Streptomyces aureus, which belongs to the broad-spectrum antibiotic fungicide. It has good systemic properties, interferes with the bi...
