Abstract

The invention discloses a fungicide combination containing polyoxin, which is a fungicide combination containing active component A and active component B, the polyoxin is selected as the active component A, the active component B is selected from any of the following fungicides: ethirimol, 2-cyan-3-amino-3-ethyl aminoacrylate, bromothalonil, zineb, chlorothalonil and dithianon, and moreover, the ratio of the active component A to the active component B in part by weight is 32:1 to 1:64. The fungicide combination can prevent and control a variety of crop diseases, has a remarkable synergistic effect, broadens the antifungal spectrum, and has high activity on downy mildew, epidemic diseases, anthracnose, powdery mildew, leaf spot, fusarium head blight, rice blast and other diseases; and moreover, the dosage of pesticide is reduced, the residue of pesticide on crops is decreased, and thereby the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a binary mixed bactericidal composition containing polyoxin. Background technique [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 prevention and control objects are wheat powdery mildew, tobacco red spot, cucumber downy mildew, melon wilt, ginseng black spot, rice blight, a...
