Description

Insecticide composition

TECHNICAL FIELD The present invention relates to an insecticide composition using acid, blue, medicinal and acid peppermint.

Conventionally, inorganic compounds or organic compounds having insecticidal properties have been mainly used as insecticides for controlling pests such as rice worms and aphids, but recently, synthetic insecticides not only cause environmental pollution, but some insecticides are harmful to the human body, causing the processor to be weak. Of course, when treated with crops of mature or mature stages, pesticides remaining in the harvested crops may detoxify the human body, and thus, the development of non-toxic pesticides is urgently required.

Conventionally, pesticides using plant juices or extracts that have insecticidal or bactericidal properties or have properties that avoid pests have been studied. Insecticides using juices or extracts of these plants can be used as useful insecticides because they are not harmful to the human body, as well as no harm to crops, horticultural plants or lost water, if they are manufactured as non-toxic plants. Plant insecticides that have insecticidal efficacy and are not harmful to the human body have not been developed.

In general, what appears to be a problem in the production of pesticides using the juice or extract of the plant should be selected plants that have pesticidal or pesticidal properties only to pests that the components of the plant itself are harmless to the human body. According to Korean Patent Publication No. 66-683, insecticides are made of juices and extracts extracted from more than 10 plants growing in Sanya. The pesticides of the above-described patent inventions contain 10 or more plant juices or extracts used as herbal medicines. It is difficult to collect plants to be used as raw materials because it is required to be mixed to obtain the required insecticidal properties, and expensive and large quantities such as visas must be included as essential ingredients, so the manufacturing cost is high and it has not been commercialized.

Therefore, there is a need for insecticides that can be produced using as few types of plants as possible, and are harmless to the human body and exhibit the required pesticidal properties.

It is an object of the present invention to provide an insecticide comprising plant juice and extract which can be obtained at low cost while having no harmful effect to the human body.

The object of the present invention described above is achieved by mixing live juices of acid acids with distillates of blue water, medicinal products, and acidic peppermint.

The acid, blue, medicinal and acidic used in the present invention are all herbs that are used as herbal medicines and are not harmful to the human body and are easily collected in large quantities in the field.

In particular, in the present invention, the distillate obtained by fermentation after distillation of the clean, medicinal and acidic should be used. Acid acid is used as a repellent to prevent pests by releasing irritant colonies. When acidic acid is heated at high temperature, irritant colonies disappear, so the insecticidal effect required can be obtained by using fresh juice. On the other hand, it is possible to use fresh juices such as clean, medicinal and acidic juices, but when used as fresh juices, the juices are turbid and difficult to filter, and when the sprayers are used, the amount of juices containing components having insecticidal properties is difficult to spray. Since there is little, it is economically advantageous to distill.

The insecticide of the present invention is usefully used for controlling rice pests, but is also effective for controlling cabbage bugs and aphids. In particular, since the pesticide of the present invention is produced by fermenting a plant, it has a fertilizer effect and thus shows an effective effect as a fertilizer.

Hereinafter, the present invention will be described in detail.

The roots and leaves of acid are washed with water to remove impurities such as soil and sand, and then crushed. Separately, each leaves, stems and roots that are clean, fermented and acidified are put in a separate fermentation tank and fermented at 20-60 ° C. The fermented ones are added to a distillation tank and 2 times of water is added and then distilled. Collect the

The pesticide composition of the present invention is obtained by mixing 8-12% by weight of the juice prepared in the above, 8-10% by weight of the distillate, 25-35% by weight of distillate distillate, and 45-55% by weight of acidic distillate.

The pesticide of the present invention is treated to the leaves and stems of plants by known methods such as spraying and spraying.

The insecticide of the present invention acts effectively on rice worms, cabbage worms, caterpillars, and aphids.

The pesticides of the present invention are all medicinal plants, so there is no harm to the human body as well as no harm to crops, and in particular, the effect is to promote the growth and growth of plants.

In particular, the plants used in the present invention not only can be easily collected in the acid, but also exhibits an effective insecticidal effect using only four kinds of plants, and thus, there is an advantage in that the collection and processing of raw materials can be easily produced at low cost.

EXAMPLE

10 kg of acid and roots and leaves were ground, 20 L of water was added, and the resulting juice was filtered to obtain 20 L of acidic juice.

The roots, stems, and leaves of blue, green, and peppermint were put in separate fermenters, each 10 kg, sprayed with 5 L of water and fermented at 25 ° C for 30 days. Fermented blue water, medicinal product, and acidic peppermint were put in a distillation with a condenser, and 25 liters of water were added thereto, followed by distillation for 30 minutes while heating to 100 캜 to obtain 20 liters of distillate.

100 ml of acidic juice, 100 ml of fresh distillate, 300 ml of distillate for distillation, and 500 ml of acidic distillate are mixed to obtain a liquid insecticide.

[Test Example]

20 ml of the pesticide stock solution prepared in Example 1 was diluted with 100 ml of water, and then 5 ml was sprayed into a 1 m 3 sized glass box containing 50 rice bulbs, and the number of insects killed after a predetermined time was measured. The test results are shown in Table 1.

In the same manner, the same test was carried out using acidic juice, fresh distillate, distillate of distillate, and acidic distillate alone, and the test results are shown in Table 1.

TABLE 1

As can be seen in the above table, each of the medicinal herbs used in the present invention was not great insecticide when used alone, but excellent insecticide when four ingredients were mixed.

Claims (1)

After pressing the fermentation of the blue water, brewing and acidic peppermint separately, distilled with 2 times water, 8-12% by weight of the blue-green distillate, 25-35% by weight of distillate distillate and 45-55% by weight of acidic distillate were compressed And a pesticide composition obtained by mixing with 8-12% by weight of the acidic juice obtained by filtration.
