Abstract

The invention relates to a fungicide combination with a synergistic effect. The active components of the fungicide combination include polyoxin and cyprodinil or pyrimethanil, wherein the weight ratio of the polyoxin to the cyprodinil or the pyrimethanil is 64:1 to 1:64, and aids and excipients are added into the active components, so that water-dispersible granules, wettable powder and the like for preventing and controlling diseases caused by ascomycetous, basidiomycetous and deuteromycetous fungi are prepared.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a compound bactericidal composition containing polyoxin and pyrimidine compounds on crop diseases. technical background [0002] Polyoxin (polyoxin), molecular formula: C 17 h 25 N 5 o 14 , chemical name peptide pyrimidine nucleoside. [0003] Structural formula: [0004] Polyoxin is a broad-spectrum antibiotic with good systemic conduction. Its mechanism of action is to interfere with the biosynthesis of chitin in the bacterial cell wall. After the germ tube and mycelia are exposed to the drug, they will locally expand, rupture, and overflow the cell. Inclusions, but can not develop normally, leading to death, and also inhibit the sporulation of bacteria and the expansion of lesions, the drug has no toxicity to animals, and has no phytotoxicity to plants. The main control objects are wheat powdery mildew, tobacco red spot, cucumber downy mildew, melon...
