Embodiment 17～32
[0045] Embodiment 17~32 water dispersible granules
[0046] Combine pyraclostrobin, active ingredient B, dispersant, wetting agent, binder (optional), disintegrant, and filler through airflow pulverization to obtain the required particle size, and obtain the 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 relates to an ametoctradin-containing bactericidal composition, containing an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from ametoctradin, the active ingredient B is selected from any of the following compounds: chlorothalonil, captan, fosetyl-aluminium, dithianon or famoxadone, and the weight ratio of the active ingredient A to the active ingredient B is equal to (1: 80)-(80: 1). The bactericidal composition has higher activity for multiple diseases of multiple crops, has an obvious synergistic effect, and expands a bactericidal spectrum. Furthermore, the ametoctradin-containing bactericidal composition has the characteristics of being less in dosage, rain-wash-resistant and obvious in synergism.
Description
[0001] This application is a divisional application. The original application is a patent application of Shaanxi Thompson Biotechnology Co., Ltd. "A fungicidal composition containing pyramethazone". The application number of the original application is: 201210521341.4, and the original application date is 2012.12.06. technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing pyraclostrobin on crop diseases. technical background [0003] Ametoctradin (Ametoctradin) chemical name: 5-ethyl-6-octyl[1,2,4]triazolo[1,5-a]pyrimidin-7-amine, ametoctradin class of fungicides. Inhibitor of mitochondrial respiration, acts on complex III inhibition. [0004] In the actual process of agricultural production, the most likely problem in disease prevention and control is the emergence of bacterial resistance. Combination of ingredients from different varieties is a very common method to prevent...
