Embodiment 15～28
[0043] Embodiment 15~28 water dispersible granules
[0044] Spiromethin, 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 mite-killing composition. The mite-killing composition comprises an active component A and an active component B. The active component A is selected from spiromesifen. The active component B is one compound freely selected from clofentezine, azacyclotin, fenbutatin oxide, flutenzine and bromopropylate. The weight ratio of the active component A to the active component B is 1:80-60:1. The mite-killing composition can be used for the control a plurality of harmful mites and has obvious synergistic effects. The mite-killing composition is capable of reducing the using amount of pesticides, reducing the quantity of pesticide residual on crops, and reducing the environment pollution.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an acaricidal 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] However, in the actual process of agricultural production, the most likely problem in the control of pest mites is the generation of pesticide resistance of pest mites. The compounding of ingredients from different species is a very common way to control resistant pest mites. Different ingredients are compounded, and according to the actual application...
