Embodiment 125

[0181] Example 1 25% flufenapyramide + 50% pyraclostrobin wettable powder

[0182] flufenapyramide

[0183] The active ingredient, various additives and fillers are mixed according to the proportion of the formula, and after being pulverized by an ultra-fine pulverizer, 25% flufenapyramide + 50% pyraclostrobin wettable powder can be obtained.

Embodiment 2

[0184] Example 2 10% flufenapyramide + 15% pyraclostrobin EC

[0185] flufenapyramide

[0186] Prepare the above-mentioned ingredients according to the proportion, and stir evenly to obtain a homogeneous phase.

Embodiment 36

[0187] Example 3 6.7% flufenapyramide + 11.3% pyraclostrobin water dispersible granules

[0188] flufenapyramide

[0189] Mix flufenapyramide, pyraclostrobin active ingredient, dispersant, wetting agent, disintegrating agent and filler according to the proportion of the formula, and then crush it into a wettable powder by airflow; then add a certain amount of water to mix and extrude Pressed material. After drying and sieving, 6.7% flufenapyr hydroxylamine + 11.3% pyraclostrobin water-dispersible granules were obtained.

Abstract

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