Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises active components including pydiflumetofen and captan, wherein a weight percentage ratio of pydiflumetofen tocaptan 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 plants and 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 invention relates to a bactericidal composition; the invention also relates to the application of the bactericidal composition in the field of agriculture or horticulture in controlling or preventing plant pathogenic fungi from infecting plants. Background technique [0002] With regard to pesticide activity, especially for crop protection, one of the core issues of research carried out in this technical field is the improvement of properties, especially in terms of 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. Fluconazole is a formamide microbicide developed by Syngenta. Fluconazole has been disclosed in WO2010 / 063700. Fluconazole has high activity against wheat scab, strawberry powdery mildew, tomato leaf mold, banana leaf spot and banana scab....
