Problems solved by technology

The above two patents also disclose that the combination of kresoxim-methyl and epoxiconazole can be prepared into water-dispersible granules, but the water-dispersible granules disclosed in the above two patents have no foamability, suspension rate, and disintegration. Very good, and the fluidized bed granulation method and the extrusion granulation method are respectively used for granulation, which is not convenient for continuous production, and the manufacturing cost is relatively high

Abstract

The invention discloses bactericidal composition containing epoxiconazole and kresoxim-methyl and a preparation method thereof. Effective components include epoxiconazole and kresoxim-methyl. Weight ratio of the epoxiconazole to the kresoxim-methyl is 1:8.5-28. The invention further discloses a preparation method of the bactericidal composition. The preparation method of the bactericidal composition is simple, convenient to operate, low in energy consumption and environment-friendly, continuous production can be achieved, and the obtained composition is excellent in performances of dispersibility, foamability, disintegration, suspension rate and the like, high in efficacy, highly effective in sterilization and convenient to popularize and apply.

Description

technical field [0001] The invention relates to a fungicidal composition of epoxiconazole and kresoxim-methyl and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Both econazole and kresoxim-methyl can be used to control fungal diseases on fruit trees, vegetables, flowers and cereals. However, with the increase of the application period, the resistance of fungal diseases to single agents increases year by year, and the dosage needs to be increased. The bactericidal effect can only be achieved with the number of times of medication, which not only increases the cost, but also increases the environmental pressure. The above problems are solved by compounding epoxiconazole and kresoxim-methyl in a certain proportion, which is of great significance for practical application. [0003] Both patent CN101416629A and patent CN101536690A disclose a fungicide composition containing kysstrobin and epoxiconazole. The dosage is ...
