Zusammenfassung: | The invention discloses pesticide special for a tangerine tree and a preparation method of the pesticide. The pesticide is prepared from, by weight, 10-20 parts of black false hellebore, 10-20 parts of melia azedarach, 10-20 parts of derris and 20-40 parts of allicin. The pesticide is prepared through the steps of drying, smashing, solvent extracting, filtering, concentrating, mixing, grinding and the like. Pest killing functions of black false hellebore, melia azedarach, derris and allicin are fused; if the pesticide is added to fertilizer for the tangerine tree, invasion of pests can be effectively prevented, the capacity of the tangerine tree for resisting diseases and pests is improved, and therefore the yield and quality of the tangerine tree are improved. The pesticide is free of pollution and residues, green and environmentally friendly. |
