NATURAL VERMIN EXTERMINATOR USING EXTRACT OF RHUS VEMICIFLUA, PROCESS FOR PREPARING THE SAME AND METHOD FOR SCATTERING THEREOF}

The present invention relates to a natural insect repellent for controlling pests using a lacquer tree containing urushiol, a method for producing the same, and a method for spraying the manufactured natural insect repellent.

When spraying pesticides, trace chemicals penetrate into the human body through the respiratory or skin exposure areas. Pesticides penetrated into the body are dizziness, numbness of the hands and feet, itching of the skin, limb paralysis, fainting, and visual impairment. This is a serious problem, especially in rural areas where the use of pesticides is high.

In addition, residual pesticides affect the soil and crops, causing environmental pollution problems, causing considerable difficulties for those who want eco-friendly organics.

In order to solve such a problem, researches on technologies using natural substances that are harmless to the human body have been conducted, and related technologies include fish extracts and ginseng extracts of Patent No. 10-0834965 (published date 2008.06.03). Natural insecticidal composition, pesticides containing essential oils extracted from plants such as baekhwa of Patent No. 10-0463627 (published date 2004.12.29), Patent No. 10-0498228 (published date 2005.07.01) insecticide using a ginkgo leaf extract and It discloses a natural insecticide as a biopesticide using the wormwood extract and Ginseng extract of the Republic of Korea Patent Publication No. 2005-0115521.

However, the above-described techniques are expensive for practical use or poor for controlling pests, and thus are inappropriate for spreading to farms.

Therefore, it is a time to develop a technology that is inexpensive and excellent in controlling pests so as to be practically used in farms.

Accordingly, the applicant has developed a natural pest repellent using the lacquer tree, which has been used as a conventional insect repellent in the private sector.

Sumac is a deciduous tree that is cultivated in China, Japan, and Korea. The lacquer is used to make lacquer chickens and lacquers in the private sector, and has been used as a cold-blooded person and fish-blood agent. Recently, efforts are being made to use anticancer drugs and pneumonia drugs using the pharmacological effects of lacquer.

The purpose of the present invention is to remove urushiol, a liver toxic substance of lacquer tree, which is generally used as an insect repellent, to remove residual toxicity, and to be effective in controlling pests while harmless to human body by using flavonoid components, celine, and pulley phenol components in lacquer trees. The present invention provides a natural insect repellent using sumac, a method for producing the same, and a method for spraying the same.

In order to achieve the above object, the present invention is to prepare an insect repellent using the lacquer bark extract, montmorillonite, Baydelite, nontronite, saponite, hectorite, haloyi in 98 ~ 99.5wt% of the oak bark extract 85 to 95 wt% of the mixture (A) formed by adding 0.5 to 2 wt% of any one or two or more diluents selected from among sight, brooksite or germanium;

One or two or more diluents selected from montmorillonite, baydelite, nontronite, saponite, hectorite, halosite, brookite, elite or germanium in 98 ~ 99.5wt% of the concentrated solution Adding and stirring to prepare a mixture,

Method for producing a natural insect repellent using the lacquer tree comprising the step of adding any one or two or more insecticide aids selected from lacquer wood vinegar solution, high ginseng enzyme solution or sulfur agent to the mixture, and further adding a surfactant thereto;

Diluted natural insect repellent prepared in this way from 200 to 4,000 times, 3 to 9 days intervals on larva larvae, Pampana moth, larvae, worms, powdery leaf moth mites, leafy vegetables, fruit trees, flowers Natural insect repellent using the lacquer, characterized in that the spraying method of the main technical configuration.

Hereinafter, the technical configuration will be described in detail.

The lacquer is any one or more selected from dog lacquer, oak, lacquer, vine lacquer, thistle lacquer, and mountain lacquer, and preferably use the lacquer.

First, in order to remove urushiol, a liver poison of lacquer tree, the lacquer tree is dried and peeled off, or the steam is extracted during the extraction process to obtain an extract containing active ingredients (flavonoids, etc.) except urushiol.

The dry lacquer bark maintains a water content of 10 to 20%, and if the water content is less than 10%, extraction of the active ingredient may not be easy, and when it exceeds 20%, it is not easy to grind or the concentration of the extract liquid. Since it may fall, it is preferable that the dried sumac bark maintains a water content of 10 to 20%.

Extraction is to use a high pressure water bath, and put the crushed lacquer bark powder into a high pressure water bath to obtain the extract by extracting hot water for 4 to 10 hours at 1.0 ~ 2 at a temperature of 110 ~ 140 ℃, If the temperature is less than 110 ℃ has a disadvantage in that it takes a lot of time for the extraction, if it exceeds 140 ℃ it may not be easy to extract the active ingredient is preferable to maintain 110 ~ 140 ℃. And if the hot water extraction is less than 4 hours, the yield of the extract may drop, if more than 10 hours is meaningless because the extraction is completed.

Soluble solids (brix) of the concentrated solution is maintained at 10, it is preferable to maintain the numerical value because the insect repelling effect may fall when out of the range.

The lacquer wood vinegar is produced by natural cooling condensation of the smoke generated by heating the lacquer at a temperature of 350 ℃ or more charcoal, it serves as an adjuvant of insect repellent by the action of sterilization. In addition, the sulfur agent has a bactericidal action against powdery mildew, rust disease, etc. of various crops and at the same time insecticides on mite and pod beetle of fruit trees, and sulfur-based sulfur or a sulfur-based component mixed with lime to sulfurized polysulfide Inorganic sulfuric agent of lime sulfur mixture is used.

In addition, the natural insect repellent is used to dilute to 200 times to 4,000 times by using water, when the dilution is less than 200 times, a problem occurs that the unit cost increases, if the repellent exceeds 4,000 times Since the effect as a degradation may be reduced, it is preferable to use the natural insect repellent diluted to 200 times to 4,000 times using water.

The diluted natural insect repellents are sprayed every 3 to 9 days to larvae, pampana moths, thrips, worms, powdery leaf moth, aphids, leafy vegetables, fruit trees, and Huawei.

The natural insect repellent using lacquer trees as described above can be used in place of the toxic pesticides used in farms by using natural materials, thereby ensuring safety for workers, and insecticides using natural materials that have been proposed in the past. Considering the high price, it can be manufactured inexpensively, and thus the practical use is high, and pest control effects such as larvae, pampa moth, whiskers, worms, powdery leaf moth mites, and aphids are high.

Hereinafter, the technical configuration will be described in more detail through embodiments.

Example 1: Natural Insect Repellent

99 g of oak bark extract was prepared by adding 1 g of elite and germanium in the same ratio to prepare a mixture. The mixture was prepared by mixing 95 g of 100 g of the mixture, 3 g of lacquer vinegar solution and 2 g of secondary alkanesulfonate.

Example 2: Preparation of Natural Insect Repellent

In order to increase the flavonoid content of the lacquer tree, a certain wound is made on the upper, middle, and lower ends of the tree, and the bark is felled and peeled and dried to lower the moisture content to 10% to crush it into powder.

Put the sumac powder in a high pressure water bath and extract the hot water at 110 ℃ for 1.4 hours at 1.4 atm to make a primary extract, and then put the extract in a concentrator to concentrate to 10 brix (brix) to prepare a concentrated solution.

Then, 1 g of elite and germanium were added to 99 g of the concentrated solution prepared in the same ratio to prepare a mixture, and 95 g of 100 g of the prepared mixture was mixed with 3 g of lacquer vinegar solution and 2 g of secondary alkanesulfonate. Complete the repellent.

Example 3: Natural Insect Repellent Spraying
