Embodiment 1

[0178] Example 1 10% fluconazole hydroxylamine + 80% thiophanate methyl wettable powder

[0179] Fluconazole

[0180] The active ingredients, various additives and fillers are mixed according to the proportion of the formula, and then pulverized by an ultrafine grinder to obtain 10% fluconazole hydroxylamine + 80% thiophanate methyl wettable powder.

Embodiment 2

[0181] Example 2 10% fluconazole hydroxylamine + 50% thiophanate methyl water dispersible granules

[0182] Fluconazole

[0183] Mix fluconazole hydroxylamine, methyl thiobacillus flexibilities, dispersants, wetting agents, disintegrants and fillers according to the formula ratio, and then pulverize into a wettable powder through airflow; then add a certain amount of water to mix and extrude Press the material. After drying and sieving, 10% fluconazole hydroxylamine + 50% thiophanate methyl water dispersible granules are obtained.

Embodiment 3

[0184] Example 3 3% fluconazole hydroxylamine + 30% thiophanate methyl suspension emulsion

[0185] Oil phase:

[0186] Fluconazole

[0187] water box:

[0188] Thiophanate methyl

[0189] Dissolve fluconazole hydroxylamine in N-methylpyrrolidone, add ethoxylated castor oil to obtain the oil phase; according to the formula, mix thiophanate-methyl, polyoxyethylene tristyrylphenol (10-20mol ethylene oxide) ), the water is ground and / or high-speed shear to obtain an aqueous suspension of thiophanate-methyl; the oil phase is added to the water phase under stirring to obtain the suspension.

Abstract

The invention provides a bactericidal composition. The bactericidal composition comprises active components including pydiflumetofen and thiophanate-methyl, wherein a weight percentage ratio of pydiflumetofen to thiophanate-methyl 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 phytopathogencarried 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 the field of agriculture or horticulture to prevent or prevent plant pathogenic fungi from infecting plants. Background technique [0002] Regarding the activity of pesticides, especially for crop protection, one of the core issues of research carried out in this technical field is to improve performance, especially the performance of biological activity and the performance of maintaining this activity for 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. The trifluxamide compound is a formamide microbicide developed by Syngenta. Fluconazole has been disclosed in WO2010 / 063700. Fluconazole hydroxylamine has high activity against wheat head blight, strawberry powdery mildew, ...
