Abstract

The invention discloses a bactericidal composition comprising fluxapyroxad and thiocarbamate. The composition comprises an active component A selected from fluxapyroxad and an active component B which is any compound selected from mancozeb, metiram, zineb, and propineb. A weight ratio of the active component A to the active component B is 1:80-60:1. The composition has high activity against various diseases on various crops, and has significant synergetic effect and expanded bactericidal spectrum. The composition also has the characteristics of low dosage, rainwater scouring resistance, and significant synergetic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application on diseases of a fungicidal composition containing flupyroxystrob and thiocarbamate. technical background [0002] Fluxapyroxad chemical name: 3-(difluoro)-1-methyl-N-(3',4',5'-trifluoro[1,1'-biphenyl]-2-yl) -1-H-pyrazole-4-amide, pyrazole amide fungicide, succinate dehydrogenase inhibitor. Combines superior long-lasting potency with sustained delivery properties. [0003] Mancozeb (Mancozeb) chemical name: ethylene bisdithiocarbamoyl manganese and zinc complex salt. A protective fungicide with a broad bactericidal spectrum. It mainly inhibits the oxidation of pyruvate in bacteria. It is effective against various diseases such as anthracnose and early blight on fruit trees and vegetables. At the same time, it is often mixed with systemic fungicides to delay the emergence of resistance. [0004] Metiram chemical name: tri[ammonia]ethylene bis(dithiocarbamate)...
