Description

[0001] Natural insecticide composition [0002]

The present invention relates to a natural insecticidal composition containing, as a main ingredient, a natural raw material harmless to plants and human body, and includes a technique of dissolving vegetable and animal oils in natural plant ingredients without emulsifying in water.

Pesticides are drugs that kill insects that harm humans and crops. The spread of insecticides in sanitary insect control, crop protection and forest protection is on the rise. Recently, due to the cause of persistent pesticides, DDT and other organic chlorine are no longer sprayed and the use of low toxicity natural acid pesticides is increasing.

Pesticides can be classified into contact agents, digestive toxins and gas agents according to the effects on insects. Depending on how the insecticides are present and dispersed in the treated plants, residual insecticides and granules with local effect (local effect) , Which can be divided into systemic insecticide, which is sprayed on the soil, the active ingredient is absorbed by the plant and has a long-term control effect.

It is a medicine used for pest control by extracting insecticidal ingredient contained in plants and minerals. Natural insecticides that have been developed to date are known as pyrethrins (extracted from bugs), rotethiones (extracted from the roots of Deeris), nicotine (extracted from cigarettes), and scattered (separated from the stones). Natural insecticides have long been used as pesticides and occupy a major position as pesticides until World War II, but their use has been remarkably reduced due to the development and dissemination of organic synthetic pesticides. The abundant source of new pesticides is plant essential oils. Some of these occur in food and are exempted by EPA from pesticide registration. The active ingredients of the new product include clover, rosemary, mint and orange oil. In particular, orange oil is a natural product and has low interest in the media because it has low toxicity to mammals. Orange oil is a mixture of oils extracted from orange peels, the main ingredient being a chemical called terpenes or terpenoids. The chemical relative of orange oil is turpentine. The active ingredient of orange oil is the chemical D-Limonene, which is known as an effective insecticide against a variety of pests such as flies, mosquitoes, ants, crickets and ticks. Scientists say orange oil causes a deadly chain of events that cause insects to die from huge losses of water and protein. Both food grade and technical grade orange oil are available.

Although open trials with drywood termites are rare, USDA researchers recently published an experiment with the orange oil Formosan subterranean termite, Coptotermes formosanus. They found that 96% of termites were dead in a sealed 1.9-liter (0.5 gal) plastic container containing five parts-permillion orange oil. Low-density experiments showed reduced mortality, but termites reduced their prey. When the orange oil vapor came from saturated filter paper with a delayed orange oil from the top of the vessel, the termites did not contact the source and were thus killed by fumigant activity (Raina et al. 2007).

In addition, there is no special insecticide for the bark beetle, which is a medicament of Gwangneung long woody insect or pine tree reed, which is an insecticide of oak seeds disease.

An object of the present invention is to provide an insecticidal composition using a natural raw material harmless to plants and harmless to a human body.

In addition, an insecticide or the like including a natural insecticide uses an emulsifier or an electrodeposit. In the present invention, however, an insecticidal composition is prepared by applying an oil-free oil component to an insect breathing to disturb skin respiration and maintaining a long-lasting insecticidal effect .

In order to achieve the above object, the present invention provides a natural insecticidal composition comprising a citrus oil mixture, a coffee ground extract, and a pepper seed extract as main active ingredients. The citrus oil is characterized in that it is an oil selected from the group consisting of orange, mandarin, lemon, mandarin, lime, and grapefruit. The main ingredient of orange oil is D-limonene. D-limonene is one of the most common terpenes in nature. It is a major component of various citrus oils and serves to kill insects.

The citrus oil mixture is mixed with 15 to 35% by weight of citrus oil, 30 to 55% by weight of vegetable oil, and 30 to 45% by weight of vinegar. The citrus oil has insecticidal effect and the edible oil has a duration of insecticidal effect So that mutual synergy effect is obtained.

The composition is characterized by comprising 30 to 45 wt% of a coffee ground extract, 10 to 40 wt% of an orange oil mixture, and 30 to 45 wt% of a red pepper seed extract.

The edible oil may be selected from the group consisting of soybean oil, corn oil, canola oil, sunflower oil, grape seed oil, olive oil, sesame oil, perilla oil and neem oil.

The pepper seed extract and the coffee extract are characterized in that 1 to 10% by weight of water is extracted by boiling and extracted with water during the extraction, whereby a preservative effect can be obtained

The insecticidal composition has an insecticidal activity against insects such as turtles, grasshoppers, aphids, mites, leucorrhoids, red moths, moths, larvae, larvae, yellow moths, moths, cabbage aphids, cabbage claws, pine needles and pine needles.

The insect pests can also be killed by spraying the natural insecticide composition of the present invention with 50 to 100 times of water.

The insecticide of the present invention has the advantage that it is composed of natural ingredients confirmed to have no mutation, carcinogen, and toxicity, harmless to plants and harmless to human body. In particular, insecticidal effects can be obtained by disrupting skin respiration by applying an oil component that does not have a chemical emulsifier containing a carcinogen in a skin respiratory insect, and by damaging insect skin with orange oil.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The active ingredient of the insecticidal composition of the present invention is a natural ingredient harmless to plants and human body although it kills harmful insects such as citrus oil mixture, coffee ground extract, and pepper seed extract which harms crops, various trees and grass.

Example 1: Preparation of citrus oil mixture

100 ml of cooking oil and orange oil are prepared and mixed. Orange oil is prepared by distillation after being squeezed from orange peel, and commercially available orange oil is used. Then add 100 ml of vinegar to the oil mixture and go to the mixer for 1 minute. If you do not go to the mixer, after a while, vinegar and oil components will be separated. According to the above method, the oil can be mixed with water without using an emulsifier (see Figs. 3 and 4)

The citrus oil mixture is preferably mixed with 15 to 35 wt% of citrus oil, 30 to 55 wt% of vegetable oil, and 30 to 45 wt% of vinegar, and has an advantage of exhibiting an insecticidal effect by using a small amount of citrus oil. The citrus oil, the edible oil and the vinegar may be mixed in the same amount, or they may be mixed using a half vinegar of a mixture of the citrus oil and the cooking oil without being separated from each other.

On the other hand, the orange oil mixture preferably comprises 10 to 40% by weight in the total pesticide composition.

The main ingredient of orange oil is D-limonene. D-limonene is one of the most common terpenes in nature and is a major component of various citrus oils (orange, lemon, mandarin, lime, and grapefruit). D-limonene is generally recognized as a flavoring safety (GRAS) and is listed in the codes of the federal regulations and can be found in common foods.

In the present embodiment, orange oil is used as the citrus oil, but it may be any oil extracted from citrus such as orange, lemon, mandarin, lime, grapefruit and the like containing D-limonene as a main component.

On the other hand, edible oil generally refers to oil that can be used for edible purposes, and examples thereof include soybean oil, corn oil, canola oil, sunflower oil, grape seed oil, olive oil, sesame oil, perilla oil and neem oil.

Example 2: Preparation of coffee grounds extract

250 ml of coffee grounds were put into 500 ml of water. After the coffee oil was turned off for 5 minutes or more, the coffee grounds were filtered out to remove the coffee grounds, and the coffee grounds were prepared. In particular, the coffee extract is boiled by adding 1 to 10% by weight of salt to the water during extraction, and when the salt is added, the temperature of the water is increased to about 104 ° C, and the effect of side effect is also exhibited. On the other hand, the coffee grounds may be extracted from the pressure vessel.

The coffee grounds are coffee beans which are left behind, regardless of the type of beans. Coffee beans contain moisture, ash, fat, crude fiber, crude sugar, crude protein, caffeine, etc. The proportion of each ingredient is 30%, which is the most, depending on the type and environment of the cultivation area. Joe sugar turns into caramel upon heating and becomes coffee color. Fat is the most deeply related component of coffee aroma, and it contains 12 ~ 16%. Caffeine and caffeine contain about 1.3%, which affects coffee flavor and causes excitability. The unique bitter taste of coffee is due to caffe tannic acid and contains 3-5%.

In the overall composition of the present invention, the coffee ground extract is preferably 30 to 45% by weight in the total composition, and if it is out of this range, the effect of controlling insect pests is deteriorated or the effect is not maintained.

Example 3: Preparation of extract of red pepper seeds

24 g of red pepper seeds were added to 500 ml of water, and the mixture was filtered with gauze or mesh for 5 minutes or longer to prepare a red pepper seed extract. Particularly, the extract of pepper is preferably boiled by adding 1 to 10% by weight of salt to water during extraction, and when salt is added, the temperature of the water is increased up to about 104 ° C, and the effect of side effect is also exhibited. On the other hand, the pepper seed extract may be extracted in a large amount from a pressure vessel. In the whole composition, the pepper seed extract preferably contains 30 to 45% by weight.

Capsaicin, which is a spicy taste among the components of red pepper, is richer in red pepper than red pepper shell, and it is an excellent ingredient for preventing arteriosclerosis and hypertension by preventing blood coagulation. These capsaicin components result in sterilization and insecticidal effects.

Capsaicin is used for the vegetation of crops and trees and is registered as a spoiled animal such as rabbits, squirrels, deer, rodents, raccoons, cats, dogs, and skunks. Each product, including capsaicin, is widely used and has been used to inhibit plants from being fed by insects such as termites, insects and other invertebrates.

Example 4: Preparation of pesticide composition

1. Preparation of Sample 1; An insecticidal composition was prepared by mixing 400 ml of the orange oil mixture prepared according to the above Examples 1 to 3, 300 ml of the coffee ground extract, and 300 ml of the extract of red pepper seed.

2. Preparation of Sample 2; An insecticidal composition was prepared by mixing 200 ml of the orange oil mixture prepared according to the above Examples 1 to 3, 400 ml of the coffee ground extract, and 400 ml of the red pepper seed extract.

Experimental Example: Insecticidal effect of pesticide

The insecticidal composition of Trigger Sample 1 was diluted in 50-fold water and sprayed on the ants. After spraying, the ants died after 6 hours. The ants seem to have died a few hours later because their skin is thicker than aphids or moths. (See Figures 1 and 2)

The insecticidal composition of Sample 2 was diluted in 100-fold water and sprayed on mites, Chinese cabbage aphids and cabbage claws. The insect pests died immediately upon application.

In the pesticide composition of the present invention, the insecticidal effect persisted for about one month when the aphid was observed.

Comparative Test Example: Insecticidal effect of pesticide mixed with coffee ground extract and oil

As a result of preparing a pesticide containing a mixture of coffee ground extract and oil and spraying it on the same subject as in the above experimental example, the moth died one day later and the mongoose died two days later and the aphid showed a repelling effect.

As described above, the insecticidal composition of the present invention is characterized in that the oil component of coffee derived from coffee grounds and the capsaicin of tannin component, orange oil, and pepper extract are mixed to act as a plant from various insect pests such as turtles, Chinese cabbage, It is possible to prevent the damage of the apparatus. In addition, since the effect lasts for about one month after spraying, the plant can be grown without concern for environment pollution by using the harmless ingredient which does not need to be sprinkled on the plant frequently.
