Abstract

The invention discloses a fluxapyroxad-containing sterilization composition. The sterilization composition contains an active component A and an active component B, the active component A is selected from fluxapyroxad, the active component B is selected from anyone of active ester, dithianon, fosetyl-aluminum, chlorothalonil and captan, and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a high activity against a plurality of diseases on a plurality of crops, has an obvious synergistic effect, enlarges the sterilization spectrum, and has the characteristics of small drug dose, rain wash resistance and obvious synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing flupyroxyroxamide on crop diseases. technical background [0002] Fluxapyroxad (Fluxapyroxad) chemical name: 3-(difluoro)-1-methyl-N-(3',4',5'-trifluoro[1,1'-biphenyl]-2-yl) -1-H-pyrazole-4-amide, a pyrazole amide fungicide, succinate dehydrogenase inhibitor. Combines superior long-lasting potency with sustained delivery properties. [0003] Dicyanoanthraquinone (dithianon) chemical name: 2,3-dicyano-1,4-dithioanthraquinone, molecular formula: C 14 h 4 N 2 o 2 S 2 . Dicyanoanthraquinone has multiple mechanisms of action, inhibiting a series of fungal enzymes by reacting with sulfur-containing groups and interfering with cellular respiration, and finally leading to disease death. While having good protective activity, it also has certain therapeutic activity. [0004] Aluminum triethylphosphonate (fosetyl-aluminium) ...
