Embodiment 14～24
[0041] Embodiment 14~24 water dispersible granules
[0042] Silfluazole, active ingredient B, dispersant, wetting agent, disintegrating agent, binder (optional), and filler are pulverized together by airflow to obtain the required particle size, and the granulation material is obtained. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying. See Table 2 for details.

Abstract
The invention discloses a simeconazole-containing sterilization composition. The sterilization composition contains an active component A and an active component B, the active component A is simeconazole, the active component B is selected from ethirimol or its salts, simeconazole, and prochloraz or its salts, and a weight ratio of the active component A to the active component B is 1:80-60:1. The composition has a high activity against of a plurality of diseases on a plurality of crops, has an obvious synergistic effect and an enlarged sterilization spectrum, and also has the characteristics of small consumption, rain wash resistance and obvious synergy.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing silfluazole to crop diseases. technical background [0002] Simeconazole (simeconazole), molecular formula: C 14 h 20 FN 3 OSi, chemical name: (RS)-2-(4-fluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-(trimethylsilyl)propan-2 -Alcohol, silfluazole is a sterol demethylation inhibitor, which destroys and prevents the biosynthesis of ergosterol, an important component of the cell membrane of bacteria, resulting in the failure of cell membrane formation and the death of bacteria. Because of its good systemic properties, it can be quickly absorbed by plants and conducted internally; it has good protective and therapeutic activities. Significantly increase crop yield. [0003] The salt of pyrithrimol is pyrithrimol sulfonate, which also has good bactericidal activity. At the same time, the salts of prochloraz, which are manganese s...
