The present invention provides m-diamide-based compounds and methods and applications for their preparation. The m-diamide-based compound has a structure represented by Formula I. The m-diamide-based compound according to the present invention has a high insecticidal activity at a low usage amount, and since it exerts a fast exerting effect, it can exert an insecticidal activity 1 day after administration and can reach a very high insecticidal activity within 3 days. Therefore, it has good fast-acting properties. In addition, since the effect is good at low usage, it is possible to reduce the harm to plants and humans due to the drug concentration being too high, and when applied, the drug residue is less, which makes it more beneficial for environmental protection and has a broad application prospect. |
