Problems solved by technology

[0002] For a long time, people have achieved remarkable results by using chemical pesticides to control diseases and insect pests, but the long-term use of chemical pesticides has also brought the following problems: pollution of the environment, soil compaction, excessive residues, and affect the health of humans and animals
At the same time, due to the long-term use of chemical pesticides, some pests have developed obvious resistance, which reduces the control effect of chemical pesticides. In order to ensure the insecticidal effect, the amount of chemical pesticides continues to increase, which increases the cost of pest control and increases the use the burden of

Embodiment 1

[0048] Each component is proportioned according to the following weight percentages:

[0049] Capsaicin: 0.5%, ethanol: 10%, emulsifier A3: 5%, emulsifier A4: 2%, dispersant FC: 5%, antifreeze agent D: 4%, thickener C2: 1%, hypertonic Agent polyoxyethylene ether compound: 2%, the rest is water.

[0050] Put capsaicin in a beaker, dissolve it with ethanol, then add emulsifier A3, emulsifier A4 and hypertonic agent polyoxyethylene ether compound, and mix evenly to obtain an oil phase mixture.

[0051] Put water in a beaker, add dispersant FC, thickener C2, and antifreeze D to the water in sequence and mix evenly to obtain an aqueous phase mixture.

[0052] Finally, under the condition of high-shear stirring, the oil phase mixture was added into the water phase mixture, and mixed homogeneously for 5 minutes at a rotation speed of 5000 rpm to obtain an insecticidal emulsion in water containing capsaicin.

Abstract

The invention relates to the technical field of biopesticide, and in particular relates to capsaicin-containing pesticidal aqueous emulsion. The capsaicin-containing pesticidal aqueous emulsion comprises the following components in percentage by weight: 0.5%-2% of capsaicin, 5%-20% of a solvent, 5%-15% of an emulsifier, 3%-10% of a dispersing agent, 2%-8% of an anti-freezing agent, 0.5%-2% of a thickener, 1%-5% of a hypertonic agent, and the balance of water. The preparation method of the capsaicin-containing pesticidal aqueous emulsion comprises the following steps of: firstly, preparing the components according to the set weight percentage; secondly, adding the capsaicin in a reactor, dissolving the capaicin with alcohol, adding the emulsifier and uniformly mixing the components to obtain an oil-phase mixture; adding the dispersing agent, the thickener and the anti-freezing agent to the water and uniformly mixing the components to obtain a water-phase mixture; and finally, mixing, shearing and stirring the oil-phase mixture with the water-phase mixture for 5 minutes to 10 minutes to obtain the capsaicin-containing pesticidal aqueous emulsion. The pesticidal aqueous emulsion belongs to botanical pesticides, and is green and environment-friendly and pollution-free to the ecological environment, so the pesticidal aqueous emulsion is an ideal, safe and pollution-free green pesticide.

technical field [0001] The invention relates to the technical field of biological pesticides, in particular to an insecticidal aqueous emulsion containing capsaicin. Background technique [0002] For a long time, people have achieved remarkable results by using chemical pesticides to control diseases and insect pests, but the long-term use of chemical pesticides has also brought the following problems: pollution of the environment, soil compaction, excessive residues, and affect the health of humans and animals. At the same time, due to the long-term use of chemical pesticides, some pests have obvious resistance, which reduces the control effect of chemical pesticides. In order to ensure the insecticidal effect, the amount of chemical pesticides continues to increase, resulting in increased costs for pest control and increased use the burden of the recipient. [0003] With the enhancement of people's awareness of environmental protection, the production and use of highly to...
