Problems solved by technology

After research by the inventors, it was found that compounding silfluazole with polyoxin, thiophanate-methyl, carbendazim, pyrimidine nucleoside antibiotics, and activated esters has a good synergistic effect within a certain range. Moreover, there are no relevant reports on the compounding of silfluazole with polyoxin, thiophanate-methyl, carbendazim, pyrimidine nucleoside antibiotics, and activated esters at home and abroad.

example 1～18

[0043] Instance 1~18 wettable powder

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

example 19～34

[0048] Example 19~34 water dispersible granules

[0049] Silfluazole, active ingredient B, dispersant, wetting agent, binder (optional), disintegrant, and filler are crushed 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 bactericidal composition containing simeconazole, which contains an active component A and an active component B, wherein the active component A is selected from simeconazole; the active component B is selected from any one of polyoxin, thiophanate-methyl, carbendazol, pyrimidine nucleoside antibiotics and acibenzolar; and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition disclosed by the invention has higher activity for multiple diseases on multiple crops, and has obvious synergistic action, thereby widening the bactericidal spectrum. The composition has the characteristics of small dosage, rainfall erosion resistance and obvious synergistic action.

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] Molecular formula of simeconazole: 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] Another name for pyrimidine nucleoside antibiotics: Nongkang 120. [0004] In the actual process of agricultural production, the most likely problem in disease control is...
