example 1～16

[0043] Example 1~16 wettable powder

[0044] Mix silfluazole, active ingredient B, dispersant, wetting agent, and filler, mix uniformly in a mixing tank, pulverize with a jet mill, and then mix uniformly to produce the wettable powder product of the present invention. See Table 1 for details.

[0045] Table 1 Example 1~16 each component and content

[0046]

[0047] New preparations can be obtained by exchanging mancozeb, propineb, zinc and mancozeb in the table.

example 17～32

[0048] Example 17~32 water dispersible granules

[0049] Silfluazole, active ingredient B, dispersant, wetting agent, binder (optional), disintegrant, and filler are air-pulverized 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 sterilization composition containing simeconazole and thiocarbamates. The sterilization composition comprises an active component A and an active component B, wherein the active component A is selected from simeconazole; the active component B is any one selected from mancozeb, thioneb, zineb and propineb; and a weight ratio of the active component A to the active component B is 1 : 80-60 : 1. The composition has relatively high activity for a plurality of diseases of a plurality of crops, has an obvious synergistic effect, broadens a sterilization spectrum, and has the advantages of small dosage, resistance to rain wash, and obvious synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application on diseases of a fungicidal composition containing silfluazole and thiocarbamate. 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] Mancozeb (Mancozeb) chemical name: ethylene bisdithiocarbamoyl manganese and zinc complex salt. A protective fungicide with a broad bactericida...
