Embodiment 11～20

[0041] Embodiment 11~20 water dispersible granules

[0042] Spiromethin, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. 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 can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 2 for details.

Abstract

The invention discloses an efficient insecticidal composition containing spiromesifen. The efficient insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from spiromesifen; the active ingredient B is selected from any one of the following compounds: pymetrozine, pyriproxyfen and dicyclanil; the weight ratio of the active ingredient A to the active ingredient B is (1:60)-(70:1). The composition disclosed by the invention has a synergistic effect on various pests generating hazards to agricultural production and is capable of reducing the pesticide dosage, the pesticide residue on crops and environment pollution, safe to human and livestock, good in environment compatibility and not easy to cause pest resistance to pesticides.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency insecticidal composition containing spiromethin on crop pests. Background technique [0002] Spiromesifen chemical name: 3-(2,4,6-trimethylphenyl)-2-oxo-1-oxaspiro[4.4]non-3-en-4-yl-3,3 -Dimethylbutyrate, molecular formula: 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 larvae stage, and at the same time, it can also produce ovariectal closure, reduce the incidence of mites and whiteflies The reproductive capacity of adults greatly reduces the number of eggs laid. [0003] Pymetrozine, pyriproxyfen, and cyclopronil are common insecticides widely used in crop diseases. [0004] However, in the actual process of agricultural production, the most likely problem in pest control is the generati...
