Problems solved by technology

The other type is hygienic insecticides, which are mainly used for environmental disinfection and can control the overall number of mosquitoes and flies in a certain area. The effect on mosquitoes and flies that cause harassment and bites on humans and animals is very poor, and it can treat the symptoms but not the root cause
[0004] Hygienic pesticides have a certain residue period. If they are used in food and other fields, they must pay attention to safety. Residues may lead to food safety problems
[0005] Hygienic insecticides usually have chemical components as their main components, which have certain toxicity. Long-term use will affect the environment and the health of humans and animals. Therefore, we propose a plant essential oil for repelling mosquitoes and flies, its preparation method and application

Embodiment 1

[0025] A plant essential oil for repelling mosquitoes and flies. The raw materials of the plant essential oil for repelling mosquitoes and flies include the following components in terms of parts by mass: 2 parts of peppermint, 4 parts of eucalyptus, 1 part of japonica, 2 parts of geranium, and 1 part of orange and 2 parts of wormwood. Concrete preparation method comprises the following steps:

[0026] 1) Collect flowers and leaves of peppermint, eucalyptus, muscaria, geranium, moon orange, and wormwood before they bloom, and clean them as raw materials;

[0027] 2) Air the washed raw materials to dry. When the washed raw materials are dried to dry, keep the air humidity between 2.5% and 5%, and keep the air circulation speed at 0.2m / s-0.5m / s between, and then mix according to the mass ratio;

[0028] 3) Adding distilled water of the same quality as the raw materials to the mixed raw materials, and then putting them into a fractionation device, performing fractional extracti...

Abstract

The invention discloses fly-repelling vegetable essential oil, prepared from, by weight, 1-3 parts of mint, 2-5 parts of eucalyptus, 2-4 parts of Lantana camara, 1-3 parts of geranium, 1-3 parts of Murraya paniculata, and 2-4 parts of Chinese mugwort. A preparation method comprises the steps of washing the picked mint, eucalyptus, Lantana camara, geranium, Murraya paniculata and Chinese mugwort, and washing to obtain raw materials; air-drying the washed materials, and mixing the materials according to a weight ratio; adding distilled water as heavy as the materials into the mixed materials, adding to a fractionator, and fractionally extracting at 60-85 DEG C to obtain extract; adding sodium chloride as heavy as the extract into the extract, extracting, filtering, and collecting an upper oil layer to obtain the finished vegetable essential oil. The fly-repelling vegetable essential oil may be sprayed to the surface of human and livestock, is nontoxic and harmless to human and livestock, is free of residue, is capable of effectively repelling flies and avoiding disturbance and bite, and is convenient to use and effective to use.

Description

technical field [0001] The invention relates to the technical field of plant essential oil application, in particular to a plant essential oil for repelling mosquitoes and flies, a preparation method and application thereof. Background technique [0002] Mosquitoes and flies harass the normal life and work of humans and animals. Most of the products on the market to repel or kill mosquitoes and flies are chemically synthesized and have certain toxicity. You must pay attention to safety when using them. Long-term use will have an impact on the environment and the health of humans and animals. Safety Effective without any side effects. [0003] Common fly and mosquito killing products are mainly divided into two categories: one is fly killing lamps, mosquito killing lamps and other equipment, which are mostly used indoors due to the need for fixed installation and passive mechanism of action, and have little effect on humans and animals working and living outdoors. The other ...
