Abstract

The invention relates to a bactericidal composite with fluopicolide and dimethomorph which is characterized in that the active components are fluopicolide and dimethomorph, the weight ratio of fluopicolide to dimethomorph is 1:30-10:1, the optimal weight ratio is 1:10-1:5, the total content of the active components is 0.5%-80% and the other components are auxiliary components. The recomposed pesticide of fluopicolide and dimethomorph can significantly promote the permeation and transmission of fluopicolide in plants, has obvious synergy, and can control the oomycete diseases of various crops effectively and delay the generation of resistibility. The bactericidal composite with fluopicolide and dimethomorph can be used for the disease control of crops such as fruit trees, vegetables and thelike, in particular to the diseases such as cucumber downy mildew, grape downy mildew, tomato downy mildew, tomato late blight, pepper phytophthora blight and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a bactericidal composition containing fluopyram and dimethomorph. Background technique [0002] Fluopicolide (English common name: Fluopicolide), chemical name: 2,6-dichloro-N-[(3-chloro-5-trifluoromethyl-2-pyridyl)methyl]benzamide. Fluopyram is an amide broad-spectrum fungicide, which has high biological activity against oomycete fungal pathogens, and has protective and therapeutic effects. Studies have shown that fluopyram exhibits bactericidal activity mainly by acting on specific proteins between the cell membrane and the cytoskeleton. This bactericidal mechanism is completely different from all currently known oomycete fungicides. Therefore, the active ingredient does not have any cross-resistance with the fungicides widely used in production at present, and can effectively prevent and control bacteria resistant to other oomycete fungicides. Fluopyram has strong permeability, ca...
