example 11～20

[0052] Example 11~20 water dispersible granules

[0053] Pyrimidin, 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 an insecticidal composite with fluacrypyrim. The insecticidal composite contains an active ingredient A and an active ingredient B. The active ingredient A is fluacrypyrim, the active ingredient B is selected from one of spirodiclofen, fenpyroximate, bromopropylate and cyflumetofen, and the weight ratio of the active ingredient A to the active ingredient B is 1:70-70:1. The composition can prevent and treat various kinds of injurious insects, has the obvious synergistic effect, enlarges the insecticidal spectrum, and can reduce the pesticide using amount, reduce the residual amount of pesticide on crops and relieve environmental pollution.

Description

[0001] This application is a divisional application. The original application is a patent application of Shaanxi Meibang Pesticide Co., Ltd. "An Insecticidal Composition Containing Pyrimidin". technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing pyrimidon 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 very 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] Spirodiclofen chemical name: 3-(2,4-dichlorophenyl)-2-oxo-1-oxospiro[4.5]dec-3-en-4-yl-2,2-dimethyl Butyrat...
