Embodiment 1

[0030] A plant source insecticidal aerosol containing azadirachtin, said insecticidal aerosol is composed of 0.3% azadirachtin, 5% neem oil, 0.2% surfactant, 8% Co-solvent, 3% emulsifier, 83.5% solvent. Wherein, as a preference, the solvent in this embodiment is eucalyptus oil, and the co-solvent is isopropanol.

[0031] Its preparation method is as follows:

[0032] (1) Dissolving the azadirachtin and neem oil in the above weight percentage in a cosolvent;

[0033] (2) Add surfactant, emulsifier, and solvent, and then fully stir until uniform to obtain an aerosol liquid medicine;

[0034] (3) Put the aerosol drug liquid into the aerosol tank, and press the propellant under high pressure to obtain the aerosol product; the temperature during the process of pressing the propellant is lower than 54°C.

[0035] It is worth noting that because azadirachtin is more sensitive to temperature, the influence of temperature should be considered when preparing this product. When the te...

Embodiment 2

[0041] A plant source insecticidal aerosol containing azadirachtin, said insecticidal aerosol is composed of 0.1% azadirachtin, 8% neem oil, 0.2% surfactant, 10% azadirachtin Co-solvent, 5% emulsifier, 76.7% solvent. Wherein, as a preference, the solvent of this embodiment is eucalyptus oil, and the co-solvent is By-120.

[0042] Its preparation method is as follows:

[0043] (1) Dissolving the azadirachtin and neem oil in the above weight percentage in a cosolvent;

[0044] (2) Add surfactant, emulsifier, and solvent, and then fully stir until uniform to obtain an aerosol liquid medicine;

[0045] (3) Put the aerosol drug liquid into the aerosol tank, and press the propellant under high pressure to obtain the aerosol product; the temperature during the process of pressing the propellant is lower than 54°C.

Embodiment 3

[0047] A plant source insecticidal aerosol containing azadirachtin, said insecticidal aerosol is composed of 1% azadirachtin, 12% neem oil, 1% surfactant, 12% azadirachtin Co-solvent, 7% emulsifier, 67% solvent. Wherein, as a preference, the solvent of this embodiment is turpentine-based vegetable oil, and the co-solvent is isopropanol.

[0048] Its preparation method is as follows:

[0049] (1) Dissolving the azadirachtin and neem oil in the above weight percentage in a cosolvent;

[0050] (2) Add surfactant, emulsifier, and solvent, and then fully stir until uniform to obtain an aerosol liquid medicine;

[0051] (3) Put the aerosol drug liquid into the aerosol tank, and press the propellant under high pressure to obtain the aerosol product; the temperature during the process of pressing the propellant is lower than 54°C.

Abstract

The invention discloses azadirachtin-containing botanical insect aerosol and a preparation method thereof and aims at solving the problem that the effect of the existing insect aerosol is not ideal. The azadirachtin-containing botanical insect aerosol comprises the following components in percentage by weight: 0.1-3% of azadirachtin, 1-20% of neem oil, 0.1-3% of a surface active agent, 8-15% of a cosolvent, 1-10% of an emulsifying agent and the balance of a solvent. The azadirachtin-containing botanical insect aerosol has the advantages that azadirachtin and neem oil are botanical natural active substances, high efficiency, low toxicity, no residue and safety for a human body are realized, indoor environment is not polluted, the requirement of people for environmental friendliness of a hygienic insecticide is met, and the azadirachtin-containing botanical insect aerosol is applicable to control of health pests in places to live, working places, dining places and the like.

Description

technical field [0001] The invention relates to a plant source insecticidal aerosol containing azadirachtin and a preparation method thereof. Background technique [0002] As a good plant-derived antifeedant, azadirachtin has a good repelling effect on a variety of sanitary pests, and is low-toxic and environmentally friendly, safe for humans and animals, and has the potential to be developed as a sanitary insecticide. At present, azadirachtin preparation products are mainly used in agriculture, and there is no development of azadirachtin hygienic insecticide spray, which is a blank in the market. [0003] Existing botanical sanitation insecticides are of a single type: hygienic pests represented by mosquitoes endanger human life through harassment, biting, parasitism, etc., and can spread disease pathogens, plague, typhoid and other epidemics, seriously threatening people. life safety. Hygienic insecticidal aerosol and because it is directly applied in the human living en...
