Embodiment 1～8
[0055] Embodiment 1~8 wettable powder
[0056] Mix spirotetramat, active ingredient B, dispersant, wetting agent, and filler, mix uniformly in a mixing tank, pulverize with a jet mill and then mix uniformly to produce the wettable powder product of the present invention. See Table 1 for details.

Embodiment 9～16
[0059] Embodiment 9~16 water dispersible granules
[0060] Spirotetramat, active ingredient B, dispersant, wetting agent, disintegrating agent, 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 invention discloses an insecticidal composition containing spirotetramat and organic tin. The insecticidal composition is mainly characterized in that the composition comprises an active ingredient A and an active ingredient B with weight ratio of 1:80-60:1, wherein the active ingredient A is spirotetramat and the active ingredient B is any one of fenbutatin oxide and azacyclotin, and the composition can be prepared into wettable powder, water dispersible granule, suspending agent, suspoemulsion, emulsion in water and microemulsion. The insecticidal composition can prevent injurious insects on wheat, cottons, fruit trees, vegetables and tea trees, has remarkable synergism, reduces pesticide dosage, is safe to human and livestock, has no pesticide injury and has good environment compatibility; the adhesive force of the composition is improved and rain washing resistance is achieved.
Description
technical field [0001] The invention belongs to the technical field of pesticides and relates to an insecticidal composition containing spirotetramat and organotins. Background technique [0002] Spirotetramat (Spirotetramat), chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5] -Decan-3-en-2-one, molecular formula: C 21 h 27 NO 5 , Spirotetramat has unique action characteristics and is a rare existing insecticide with two-way systemic conductivity. It has a wide insecticidal spectrum and a long duration of action, which can provide effective control for up to 8 weeks. It works by interfering with lipid biosynthesis in insects leading to larval death and reduced adult reproductive capacity. Due to its unique mechanism of action, it can effectively control pests resistant to existing insecticides, and at the same time, it can be used as an important species for the management of neonicotinoid insecticide resistance. [0003] Fenbutatin oxide, chem...
