[0049]

example 13～24

[0050] Example 13~24 water dispersible granules

[0051] Pyrimidin, active ingredient B, dispersant, wetting agent, binder, disintegrant, 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 efficient pesticide composition. The efficient pesticide composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is fluacrypyrim, the active ingredient B is selected from any one compound of azocyclotin, bifenazate, fenbutatin oxide and fenpropathrin, and the weight ratio of the active ingredient A to the active ingredient B is (1:80)-(60:1). The composition can control various pests and has a remarkable synergistic effect, the insecticidal spectrum is enlarged, the pesticide use amount can be reduced, the residual quantity of pesticides on crops is reduced, and environmental pollution is reduced.

Description

[0001] This application is a divisional application. The original application is a patent application "a high-efficiency pesticide composition" of Shaanxi Meibang Pesticide Co., Ltd. The application number of the original application is: 201210138455.0, and the original application date is 2012.05.05. technical field [0002] The invention belongs to the technical field of pesticides and relates to the application of a high-efficiency pesticide composition on crop pests. technical background [0003] Fluacrypyrim chemical name: Methyl(E)-2-{α-[2-isopropoxy-6-(trifluoromethyl)pyrimidine-4-phenoxy]-0-tolyl} -3-methoxyacrylate, molecular formula: C 20 h 21 f 3 N 2 o 5 . Pyrimiden was the first methoxyacrylate acaricide. It has good contact killing and stomach poisoning effects, and is effective against various characteristics of harmful mites, including eggs, nymphs, and adults, and has a good quick effect and a lasting period of more than 30 days. [0004] Azocyclotin (...
