Embodiment 19～35

[0047] Embodiment 19~35 water dispersible granules

[0048] Silfluazole, active ingredient B, dispersant, wetting agent, disintegrant, and filler are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain granulation material. 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 high-efficiency bactericidal composition containing simeconazole and triazoles. The bactericidal composition contains an active component A and an active component B, wherein the active component A is simeconazole, the active component B is a triazole bactericide which is any one compound selected from the group consisting of tebuconazole, hexaconazole, difenoconazole, metominostrobin, penconazole, propiconazole and flutriafol, and a weight ratio of the active component A to the active component B is 1: 70 to 70: 1. The bactericidal composition has high activity on a plurality of diseases of a plurality of crops, a substantial synergistic effect, a broadened bactericidal spectrum and the characteristics of a small usage amount, resistance to rain wash and substantial synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency fungicidal composition containing silfluazole and triazoles on 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] Triazole fungicides have broad-spectrum sterilization—high activity against many kinds of pathogenic fungi such as Ascomycetes,...
