Abstract

The invention discloses an efficient bactericidal composition. The bactericidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from fluopyram; the active ingredient B is selected from any one of the following compounds: dithianon, cyprodinil, captan, fosetyl-aluminum, chlorothalonil and bromothalonil; the weight ratio of the active ingredient A to the active ingredient B is 1:80 to 60:1. The composition disclosed by the invention has relatively high activity for various diseases on various crops and has a remarkable synergistic effect so that the bactericidal spectrum is expanded. In addition, the efficient bactericidal composition has the characteristics of small dosage, rain wash resistance and remarkable synergism.

Description

[0001] This application is a divisional application. The original application is a patent application "a high-efficiency fungicidal composition" of Meibang Pesticide Co., Ltd. The application number of the original application is: 201210243178.X, and the original application date is 2012.07.13. technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency bactericidal composition on crop diseases. technical background [0003] Fluopyram (Fluopyram) chemical name: N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl)ethyl]-α,α,α-trifluoro-0-toluene Amide, molecular formula: C 16 h 11 CIF 6 N 2 O, which inhibits mitochondrial respiration by hindering the electron transfer of succinate dehydrogenase in the respiratory chain. The purpose of controlling pathogenic bacteria is achieved by inhibiting several stages in the growth cycle of pathogenic bacteria. It is mainly used to prevent and control diseases caus...
