Abstract

The invention discloses a special insecticide for Shatian pomelo as well as a preparation method and application thereof and relates to the technical field of insect killing of the Shatian pomelo. Thespecial insecticide is prepared from the following components in parts by weight: 30 to 50 parts of a traditional Chinese medicine extracting solution, 1 to 5 parts of azadirachtin, 1 to 3 parts of celangulin-V, 2 to 6 parts of toosendanin, 3 to 5 parts of camptothecin, 2 to 8 parts of furanocoumarin, 3 to 8 parts of plant essential oil, 1 to 3 parts of sodium hydroxide, 0.5 to 2 parts of acetone, 1 to 6 parts of 95 percent ethanol and 1 to 3 parts of an emulsifier. After the special insecticide for the Shatian pomelo is blended with water which is 100 to 200 times of the volume of the special insecticide, a mixture is sprayed on plant parts with insect pests or whole plants, and can be used for efficiently preventing and controlling the insect pests including phyllocoptruta oleivora ashmead, scale insects, phyllocnistis citrella, Resseliella ctitrifrugis Jiang, bactrocera dorsalis, aphids and contarinia citri barnes of the Shatian pomelo, and the insect killing rate reaches 99 percent or above; the special insecticide for the Shatian pomelo has the advantages of low toxicity, easiness for degradation, no residues and no harms to people and environment, and accords with a conceptof green and pollution-free planting of the Shatian pomelo.
