Embodiment 110

[0178] Example 1 10% flufenapyramide + 80% copper calcium sulfate wettable powder

[0179] flufenapyramide

[0180] The active ingredients, various additives and fillers are mixed according to the ratio of the formula, and after being pulverized by a superfine pulverizer, 10% flufenapyramide + 80% copper calcium sulfate wettable powder is obtained.

Embodiment 2

[0181] Example 2 10% flufenapyramide + 50% copper calcium sulfate water dispersible granules

[0182] flufenapyramide

[0183] Mix flufenapyramide, copper calcium sulfate active ingredient, dispersant, wetting agent, disintegrating agent and filler according to the ratio of the formula, mix evenly, and crush it into wettable powder through airflow; then add a certain amount of water to mix and extrude to make material. After drying and sieving, 10% flufenapyramide + 50% copper calcium sulfate water dispersible granules were obtained.

Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises active components including pydiflumetofen and copper calcium sulphate, wherein a weight percentage ratio of pydiflumetofen to copper calcium sulphate 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 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...
