Abstract
The invention relates to a pesticide composite containing a lantana extract and an azolla imbricata extract, a preparation method and an application, and belongs to the field of pesticides. The invention aims at providing the pesticide composite containing the lantana extract and the azolla imbricata extract, the preparation method and the application. Active components of the pesticide composite containing the lantana extract and the azolla imbricata extract are extracted by the following raw medicinal materials in parts by weight: 1 part of lantana and 0.2-4 parts of azolla imbricata; the active components of the pesticide composite can be coextracted after the raw medicinal materials, namely the lantana and the azolla imbricata are mixed; or the active components can be formed by separately extracting the lantana, obtaining the lantana extract, separately extracting the azolla imbricata, obtaining the azolla imbricata extract, and then mixing the two extracts. The pesticide composite containing the lantana extract and the azolla imbricata extract has an obvious control effect on lepidoptera and homoptera injurious insects, and has positive significance in agricultural production.
