Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a composition for controlling environmental pests,

The present invention relates to compositions, and more particularly to compositions for controlling insects.

An insect (insect) is a collective term for an insect that directly or indirectly harms human life. It can be classified as an insect that gives direct harm and indirect harm in terms of damage to the human side (insects).

Insecticides that cause direct harm include insecticidal insects such as fleas, fleas, ticks, mosquitoes, etc., autismic insects (e.g., bees, Half wings, etc.). Examples of insects that cause indirect harm include insect damage (eg, butterflies, moth larvae, aphids, etc.), insects (wheels, moths) of products and processed products, , Paris, and so on), and pests (flies, backs, wheels, etc.) that mediate and mediate the infectious disease of manure.

These pests are increasingly affected by humans, living and breeding in a variety of places, regardless of the season, due to recent global climate change. For example, in the case of a mosquito, the sound or blood-sucking activity causes psychological and psychological damage such as sleep disturbance, discomfort, anxiety, and causes diseases such as malaria, encephalitis, dengue fever and skin allergy. In addition, pests such as cockroaches, butterflies, worms, and ticks are directly or indirectly damaging to human beings, including infectious disease transmission and mediation.

As a result, efforts to address the damage caused by pests have been actively conducted throughout the world. For example, studies on the development of insect repellents that prevent insect pests from contacting the body or insect pests, and insecticides that function to inhibit insect neurotransmission, inhibit energy production, regulate growth, and inhibit behavior It is progressing.

However, most of the repellents or insecticides developed so far are chemically synthesized products, which have adverse effects on the human body and cause many side effects such as environmental pollution. For example, synthetic organic insecticides such as Deet (N, N-diethyl1-meta-toluamide) can be used over a wide range of insects and exhibit a powerful insecticidal effect and are widely used today. However, the above substances are very toxic, have an unpleasant odor, give stimuli to the skin, and react with plastics or synthetic fibers to cause damage and discoloration, which causes many side effects to humans or ecosystems.

Therefore, it is urgently needed to study a general pest control agent that causes fatal toxicity to various insects while minimizing adverse effects on humans and ecosystems, away from insect repellents and insecticides of conventional artificial synthetic materials.

1 is a flowchart showing a method for manufacturing an environmentally-friendly pest control composition according to an embodiment of the present invention.

1, the eco-friendly pest control composition may contain plant extracts, useful microbial population metabolites, and residual water. Specifically, the plant extract may contain active ingredients having a controlling effect against pests and harmful microorganisms. The plant extract may be an extract of a single plant or a complex plant extract. For example, the plant extract may be an extract of at least one substance selected from the group consisting of cinnamon, ginkgo leaf, and insect pest. More specifically, the plant extract may be cinnamon essential oil, ginkgo biloba oil, pest control oil or a combination thereof.

The cinnamon essential oil may contain ingredients such as cinnamaldehyde, camphene, cineole and eugenol. These components exert their antimicrobial activity and can exert their controlling effect against pests and harmful microorganisms. Specifically, the components can exert a bactericidal effect against pathogenic bacteria including fungi, pathogenic Escherichia coli, Helicobacter bacteria, tooth decay bacteria, food poisoning staphylococci, and the like. These components can exert the controlling effect against pests including mosquitoes, flies, mites and the like. More specifically, among the above components, Yugenol is a colorless liquid having disinfection and analgesic action, and has a unique aroma, and can exhibit an excellent effect for mosquito repellent.

The ginkgo biloba oil may be selected from the group consisting of ginnon, alpha -hexenal, shikimic acid, bilobalides, beta-sitosterol, oxalic acid, linolenic acid linolenic acid, linoleic acid, palmitic acid, D-glucaric acid, vitamin G, hexosamines, lignins, such as ginkgetin, isogonkgetin, sciadopitysin, carotenes and quercatin. Specifically, the ginkgo biloba oil may contain flavonoids.

More specifically, among the components of the Ginkgo biloba oil, the flavonoid and alpha-hexenal can exert an excellent controlling effect against pests such as cockroaches, ants, and aphids.

The pest control oil may contain ingredients such as pyrethrin, jasmine, cinerin, and the like. More specifically, the pyrethrin can exert an excellent controlling effect against insects such as fly, aphids, aphids, aphids, moths, cockroaches and mosquitoes.

In other words, the plant extract of the composition for controlling insect pest includes all of cinnamon essential oil, ginkgo biloba oil, and pest control oil, and can exert the controlling effect against various insect pests and harmful microorganisms. As an example, the plant extract may be a mixture of cinnamon essential oil, ginkgo biloba oil, and pest control oil at a weight ratio of 1: 7: 2.

The plant extracts may be prepared by preparing each of the above-mentioned Cinnamon essential oil, Ginkgo biloba oil, and Peppermint oil, and then using the extracts as a single substance or a combination of the above extracts.

To prepare the cinnamon essential oil, cinnamon is first prepared. The cinnamon is finely ground, and then the heat treatment and the cooling process are repeated to soften. As an example, the heat treatment may be performed at 90 ° C to 95 ° C for 10 minutes. The cooling may be performed at room temperature.

The softened cinnamon can then be dissolved in a non-polar solvent to extract a lipid soluble component in the cinnamon. At this time, the mixing ratio of the cinnamon and the solvent may be 1: 7 to 1:10. Thus, the extraction efficiency of the active ingredient in the cinnamon can be further improved. As the non-polar solvent, for example, a nucleic acid may be used.

After the extracted fat soluble component is concentrated, it may be dissolved in ethanol, specifically 95% alcohol, to obtain a filtrate. Then, the filtrate can be concentrated again to obtain a concentrate with reduced alcohol content. The concentration may be reduced-pressure concentration, specifically, heating reduced-pressure concentration. At this time, the heating and pressure-reducing concentration can be performed at a temperature of about 40 to 80, for example. This may be a temperature range in consideration of the boiling point of ethanol, and the ethanol content in the concentrate may be reduced or eliminated.

To prepare the ginkgo leaf oil, ginkgo leaf is first prepared. The ginkgo leaf is dried and immersed in the alcohol. Thus, the solubility of the active ingredient in the ginkgo leaf can be increased. For example, about 2 g of ginkgo leaf was immersed in 95 ml of 10% alcohol for 60 minutes. Then, the ginkgo biloba oil component was extracted using a supercritical carbon dioxide extraction method. At this time, the optimum condition for the extraction may be 50 to 70 ° C, 100 to 200 atm.

In order to prepare the pest control oil, first, a pest control station is prepared. The bug bug is dried and immersed in the alcohol. At this time, the immersion condition may be performed for 24 hours by mixing the bug bug station and the alcohol in a ratio of 1: 1. It may then be filtered off with a sieve and then concentrated.

The cinnamon essential oil, ginkgo leaf oil and pest control oil may be prepared and stored in the form of concentrate.

The effective microorganism may be a group of microorganisms useful for about 80 kinds of human body including yeast, lactic acid bacteria, yeast group, photosynthetic bacteria, bacillus and actinomycetes. The useful microorganism group has an excellent effect for preventing oxidation, purification of water, removal of toxicity and removal of odor.

The useful microorganism group contained in the pest control composition may be metabolites of the microorganisms. Specifically, the metabolites may include organic acids, polysaccharides, amino acids, hormones, antibiotics, vitamins and the like. For example, Bacillus and actinomycetes secrete a large amount of antibiotics. To date, about 5,000 antibiotics have been known, and about 100 antibiotics useful for the human body are known. Accordingly, the control effect against various pests or pathogenic bacteria can be further enhanced. In addition, the metabolites of the beneficial microorganism group are harmless to the human body or ecosystem, and include various nutrients, and can exert various excellent purification actions. Therefore, the useful microorganism group can be applied as an environmentally friendly useful material in various industrial fields, such as agriculture, animal husbandry, horticulture, fishery, soil, architecture, industry, medical,

For example, the composition for controlling insect pests may be mixed with the plant extract and the useful microorganism group metabolites in a weight ratio of 5%: 10% to 15%: 25%.

More specifically, a mixture of the plant extract and the useful microorganism group metabolite may be mixed with a residual amount of water to prepare a composition for controlling insects. For example, for 100 parts by weight of the composition, the plant extract may comprise 1% to 10% by weight, specifically 5 to 10% by weight. The useful microbial population metabolite may comprise from 15% to 25% by weight.

The composition can be stored or used in the form of a concentrate or concentrate through the process of concentration. For example, the concentration may be reduced-pressure concentration, specifically, heating reduced-pressure concentration.

The concentrated composition may be processed into a solid, liquid or vapor phase, if desired. For example, it can be applied to products exhibiting the pest control effect, such as detergents, cosmetics, pesticides, pesticides, fragrances, and the like, but is not limited thereto.
