Description

Natural insecticide composition

The present invention relates to a natural insecticide composition containing, as a main component, a natural raw material harmless to plants and the human body, and includes a technique of dissolving vegetable and animal oils in water as a natural plant component without an emulsifier.

Pesticides are drugs that kill insects that harm people or crops. The spread of pesticides in hygienic insect control, crops and forest protection is on the rise. Recently, due to the cause of persistent pesticides, DDT and other organic chlorine agents are no longer applied, and the use of low-toxic natural insecticides is increasing.

Insecticides can be classified into contact agents, digestive poisoning agents, and gaseous agents according to their effects on insects. Residual insecticides and granules with local effects are dependent on how pesticides are present and dispersed in treated plants. In the form of the drug is sprayed on the soil, the active ingredient is absorbed by the plant can be divided into a systemic insecticide that has a long-term control effect.

A drug used for pest control by extracting pesticides contained in plants and minerals. Natural insecticides that have been developed so far are known as pyrethrins (extracted from pesticides), rotenones (extracted from the roots of Terris), nicotine agents (extracted from tobacco) and arsenic acid (separated from zeolites). Natural insecticides have been used as pesticides since ancient times, and occupied a major position as insecticides until World War II, but their use has decreased considerably due to the development and dissemination of organic synthetic pesticides. A rich source of new pesticides is plant essential oils. Some of these occur in foods and are exempt from pesticide registration by EPA. Active ingredients of the new product include clover, rosemary, mint and orange oil. Orange oil, in particular, has received much attention from the media because it is natural and has low toxicity to mammals. Orange oil is an oil mixture extracted from the orange peel and its main ingredient is a chemical called terpenes or terpenoids. The chemical relative of orange oil is turpentine. The active ingredient in orange oil is the chemical D-Limonene, an effective insecticide against various pests such as flies, mosquitoes, ants, crickets and ticks. Scientists say orange oil causes a deadly chain of events that kill insects from huge losses of water and protein. Both food grade and technical grade orange oils are available.

Although published experiments with drywood termites are scarce, USDA researchers recently published an experiment with orange oil Formosan subterranean termite, Coptotermes formosanus. They found that 96% of termites died in sealed 1.9-litre (0.5 gal) plastic containers containing five-permillion orange oil. Low concentration experiments showed reduced mortality, but allowed termites to reduce their food. When the vapor of the orange oil came from the saturated filter paper with the orange oil delayed from the top of the vessel, the termites did not come into contact with the source and thus they were killed by fumigant activity (Raina et al. 2007).

In addition, there are no special insecticides for the worm beetle that is the mediator of Gwangneung long-tree beetle and pine re-nematode, which is the mediator of oak seedling disease.

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

In addition, although insecticides including natural insecticides use emulsifiers or electrodeposition agents, in the present invention, an oil component without an emulsifier is applied to insects that breathe skin, thereby preventing insects from breathing the skin and preparing a pesticide composition that maintains a long-lasting insecticidal effect. For the purpose of

In order to achieve the above object, the present invention provides a natural insecticide composition comprising a citrus oil mixture, coffee grounds extract and pepper seed extract as the main active ingredient. Citrus oil is characterized in that the oil is selected from the group consisting of orange, tangerine, lemon, mandarin, lime, and grapefruit. The main ingredient of orange oil is D-limonene. D-limonene is one of nature's most common terpenes and is a major component of various citrus oils.

The citrus oil mixture is characterized in that the citrus oil is mixed with 15 to 35% by weight, cooking oil 30 to 55% by weight, vinegar 30 to 45% by weight, citrus oil has a pesticidal effect and cooking oil secures the duration of the pesticidal effect By having the effect of doing so, mutual synergy effect is brought about.

실시예 1: 감귤류 오일 혼합물 제조Example 1: Citrus Oil Mixture Preparation

Prepare and mix 100 ml of cooking oil and orange oil each. Orange oil is prepared by distilling the juice from the orange peel and using commercial orange oil. Thereafter, 100 ml of vinegar is mixed with the oil mixture and the mixer is allowed to go for about 1 minute. If you don't go to the mixer, over time, the vinegar and oil will separate, so be sure to grind it. By this method, oil can be mixed with water without emulsifier (see Figs. 3 and 4).

The citrus oil mixture is preferably mixed with citrus oil 15 to 35% by weight, cooking oil 30 to 55% by weight, vinegar 30 to 45% by weight, and has an advantage of exhibiting an insecticidal effect by using a small amount of citrus oil. The citrus oils, the edible oil and the vinegar may be mixed in the same amount or may be mixed without being separated from each other even when mixed using 1/2 of the vinegar of the mixture of citrus oil and the edible oil.

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

The main ingredient of orange oil is D-limonene. D-limonene is one of nature's most common terpenes and is a major component of many citrus oils (orange, lemon, mandarin, lime, and grapefruit). D-limonene is generally listed in the Code of Federal Regulations as recognized as a flavor safety (GRAS) and can be found in regular foods.

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

On the other hand, cooking oil generally means an oil usable for edible, and for example, soybean oil, corn oil, canonella, sunflower oil, grapeseed oil, olive oil, sesame oil, perilla oil, neem oil and the like can be used.

실시예 2 : 커피찌꺼기 추출액의 제조Example 2 Preparation of Coffee Ground Extract

250cc of coffee grounds were put in 500 ml of water, and after 5 minutes or more, until the color of coffee oil came out, the color of the water turned brown, and the coffee grounds were filtered out to remove the coffee grounds. In particular, coffee extract is extracted by boiling 1 ~ 10% by weight of salt with respect to water when extracted, and when salt is added, the temperature of the water rises to about 104 ℃, and also shows the effect of preservation. Meanwhile, the coffee grounds may be extracted from the pressure machine.

The coffee grounds are the ones left after extracting the coffee, regardless of the type of beans. Coffee beans contain moisture, ash, fat, crude fiber, crude sugar, crude protein, and caffeine. The proportion of each ingredient varies depending on the variety and the environment where it is grown, but crude sugar accounts for the highest 30%. The crude sugar turns into caramel and turns coffee color when heated. Fat is the most important ingredient in coffee, containing 12-16%. Caffeine and caffeine contain about 1.3%, which influences the taste of coffee and causes excitement. The unique bitterness of coffee is due to caffetanic acid, which contains 3 to 5%.

In the total composition of the present invention, the coffee grounds extract is preferably 30 to 45% by weight in the total composition, and beyond this range, the pest control effect is lowered or the duration of the effect is lowered.

실시예 3 : 고추씨 추출물의 제조Example 3 Preparation of Red Pepper Seed Extract

Pepper seeds 24g in 500ml of water was prepared by filtering the pepper seed extract by gauze or mesh cut for 5 minutes or more. In particular, the red pepper extract is preferably extracted by boiling 1 ~ 10% by weight of salt with respect to the water when extracted, and when the salt is added, the temperature of the water rises to about 104 ℃, and the effect of preservation is also shown. On the other hand, the pepper seed extract may be extracted in a large amount in a pressure vessel. The pepper seed extract in the total composition preferably contains 30 to 45% by weight.

Capsaicin, which has a pungent taste of red pepper, is contained in red pepper seeds more than twice as much as the skin of red pepper, and it is excellent for preventing arteriosclerosis and hypertension by preventing blood clotting. These capsaicin components have a bactericidal and insecticidal effect.

Capsaicin is used for the vegetation of crops and trees and is registered to chase vertebrate animals such as rabbits, squirrels, deer, rats, 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.
