Technical Field

[0001] The invention relates to a sanitary insecticide composition and application thereof. The active ingredients of the sanitary insecticide composition are component A and component B. Component A is a piperic acid derivative compound, and component B is any one of imidacloprid, acetamiprid, thiacloprid, thiamethoxam, dinotefuran, flupyradone and sulfoxaflor. Background Art

[0002] Due to the long-term use of pesticides, pests have become increasingly resistant to organophosphates, carbamates, and pyrethroids, and the resistance problem is becoming increasingly serious. In practical applications, highly active compounds are needed to improve the control effect and reduce the amount of pesticides used.

[0003] Chinese invention patent CN112457288 discloses a piperic acid derivative and its application, wherein compound I-72 has contact and stomach poison activity and good conduction activity. At the same time, it has not been found that compound I-72 is used in residual spraying to control sanitary pests. The compound has high activity and low drug resistance. The present invention screened out nicotine insecticides with synergistic effects with it through experiments. The compound of two agents with different action mechanisms has a significantly improved efficacy compared with the single agent of formula I, and the efficacy is significantly higher than that of commercially available products.

[0004] The structural formula of the compound is as follows:

[0005]

[0006] Residual spraying is a common method of using pesticides in the field of sanitary pest control. Traditional residual spraying requires a large amount of spraying to increase the contact surface of flies and passively kill pests.
