Problems solved by technology

[0002] Existing insecticides are mostly made of chemicals with different effects and long residual period. Although they can prevent agricultural and forestry diseases and insect pests in a short period of time, they have caused serious harm to crops, especially human bodies, for a long time.
The use of pesticides, because they contain a large amount of chemical substances, has brought more or less pollution to the air, water, soil and food after a large amount of application. At the same time, long-term consumption of chemical pesticides will also make pests resistant to pesticides.
[0003] When pesticides are applied to crops, vegetables or fruit trees, the pesticides remaining on the surface of the crops, due to their strong fat solubility, can easily penetrate into the waxy layer of the crop epidermis, making it difficult to completely wash off

Abstract

The invention discloses a high efficiency composite biological green insecticide and a preparation method thereof. The composite biological green insecticide is prepared from tobacco leaf, Melia azedarach oil, titanium dioxide, solanine, tea saponin, chromafenozide, garlic powder, sodium lignosulfonate and borax. The preparation method consists of: taking the raw materials in proportion, dissolving Melia azedarach oil in water to conduct full dissolution, performing cooling to room temperature, adding borax, and conducting stirring; adding titanium dioxide, solanine, tea saponin, chromafenozide, garlic powder and sodium lignosulfonate, performing heating stirring, adding tobacco leaf, performing stirring, conducting microwave treatment, filtering, drying and grinding into powder, thus obtaining the product. The composite biological green insecticide is prepared by compounding of biological components and natural ingredients, all the effective components supplement each other and have a synergistic effect, the insecticide has obvious control efficacy on aphids, beetles and other molluscous pests, the drug efficacy can be increased according to the insect pest condition, the drug resistance problem caused by long-term use of a same agent can be avoided, the insecticide is naturally degradable, and does not leave residue on crops or bring about health problems directly.
