Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises active components including pydiflumetofen and cyflufenamid, wherein a weight percentage ratio of pydiflumetofen to cyflufenamid is 50:1-1:50. The invention further relates to application of the bactericidal composition to control of harmful fungi and bacteria on cereals, vegetables, fruits, ornamental plantsand grape vines. The invention also relates to application of the bactericidal composition applied to places requiring prevention and control to prevent and control pathogenic or saprophytic fungi and bacteria in soil or cultivation media. The invention further relates to application of the bactericidal composition to seed treatment for protecting seeds from invasion of phytopathogen carried by the seeds.

Description

technical field [0001] The present invention relates to a bactericidal composition; the present invention also relates to the application of the bactericidal composition in controlling or preventing plant pathogenic fungi from infesting plants in the field of agriculture or gardening. Background technique [0002] With regard to pesticide activity, especially for crop protection, one of the central problems of research carried out in this technical field is the improvement of performance, especially with regard to biological activity and the maintenance of this activity over a certain period of time. [0003] Pydiflumetofen, the chemical name is 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid methoxy-[1-methyl-2-(2,4, 6-Trichlorophenyl)-ethyl]-amide. Flufenapyramide compound is a formamide microbicide developed by Syngenta. Flufenapyramide has been disclosed in WO2010 / 063700. Flufenapyramide has high activity against wheat head blight, strawberry powdery mildew, t...
