Embodiment 11～20
[0050] Embodiment 11~20 water dispersible granules
[0051] Spiromethin, active ingredient B, dispersant, wetting agent, disintegrant, and filler are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain the preparation grain materials. 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 present invention discloses a spiromesifen-containing pesticide composition, which contains an active component A and an active component B, wherein the active component A is selected from spiromesifen, the active component B is any one compound selected from spirodiclofen, fluacrypyrim, fenpyroximate and cyflumetofen, and a weight ratio of the active component A to the active component B is 1:60-80:1. The composition can be provided for preventing and controlling a plurality of harmful mites, and has characteristics of significant synergistic effect, pesticide consumption reduction, reduction of pesticide residue on crops, and environmental pollution reduction.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a spiromethid-containing pesticide composition on crop pest mites. technical background [0002] Molecular formula of Spiromesifen: C 23 h 30 o 4 . The mechanism of action of spiromethin is to affect the development of whiteflies and mites, interfere with the biosynthesis of their liposomes, especially have good activity on the larval stage, and at the same time, it can also produce ovariectal closure, reducing the incidence of mites and whitefly adults. reproductive capacity, greatly reducing the number of eggs laid. [0003] Spirodiclofen chemical name: 3-(2,4-dichlorophenyl)-2-oxo-1-oxospiro[4.5]dec-3-en-4-yl-2,2-dimethyl Butyrate, molecular formula: C 21 h 24 Cl 2 o 4 . Has a new mechanism of action, showing inhibition of lipid synthesis. Effective against all stages of mite development by contact, including eggs. [0004] Fluacrypyrim chemical...
