Abstract

The invention belongs to the field of farm chemicals and discloses a bactericidal composition containing fluazinam and difenoconazole and the application of the same. The fluazinam and the difenoconazole serve as effective components of the composition, wherein the total content of the fluazinam and the difenoconazole in mass percentage is 5% to 75%, and the mass ratio of the fluazinam to the difenoconazole is 30:1 to 1:20. The composition can be used for the preparation of a bactericide for preventing and treating diseases such as rice blast, pestilence, anthracnose, leaf mold, scab and the like caused by fungi and other pathogens of cereal crops, vegetable and fruit trees, and has the advantages of wide application range, low cost and good effect.

Description

technical field [0001] The invention belongs to the field of pesticides and relates to a broad-spectrum bactericidal composition, in particular to a bactericidal composition containing fluazinam and difenoconazole and an application thereof. Background technique [0002] Plant diseases can affect biodiversity and the ecological environment. Plant diseases often limit the cultivation of certain plants. From the 1930s to the 1970s, the Dutch elm blight destroyed the American elm and seriously deteriorated the environment; the chestnut blight made the American chestnut disappear in North America; the coffee rust prevented Sri Lanka from continuing to produce coffee. Changing to tea has greatly changed the living habits of the local people. Pine wood nematodes cause large-scale dieback of pine trees, causing great damage to ecology and natural landscapes. [0003] Fluazinam is a 2,6-dinitroaniline compound, a protective fungicide, and an uncoupler for mitochondrial oxidative p...
