Abstract
The invention discloses an efficient fungicidal composition. The efficient fungicidal composition comprises an active component A and an active component B, wherein the active component A is selected from fluopyram; the active component B is selected from any one of the following compounds: dithianon, cyprodinil, captan, fosetyl-aluminium, chlorothalonil and bromothalonil; and the weight ratio of the active component A to the active component B is (1 to 80)-(60 to 1). The composition has relatively high activity on a plurality of diseases of a plurality of crops and has an obvious synergism; the bacteriocidal spectrum is expanded; and the composition has the characteristics of low consumption of the fungicidal component, resistance to rain washing and obvious synergism.
Description
[0001] This application is a divisional application. The original application is a patent application "a high-efficiency fungicidal composition" of Shaanxi Meibang Pesticide Co., Ltd. The application number of the original application is: 201210243178.X, and the original application date is 2012-7-13. 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 diseas...
