Description

An insecticide composition and a process for preparing the same,

More particularly, the present invention relates to a composition for insecticidal use which is remarkably excellent in effect compared with a composition for insecticidal use using boric acid, and a method for preparing the insecticidal composition.

Various insect pests that cause human repellency and hygiene problems have been a problem for a long time because they are distributed in human residential areas. The biggest disgusting cockroach is known to be extremely difficult to eradicate as it has a very strong population growth potential. Because cockroaches propagate very well in environments with water, food, and cows, human settlements are the best place for cockroaches to multiply. As a method of insect pests such as ants, tillers, or zinnas including wheels, a poisoning method, a fumigation method, a spraying method, and an attracting method are used. Among them, poisoning law is the most widely used method in general households and offices, and it is a method of eradicating by mixing insecticide with proper food and attracting and eating wheels and ants.

Pesticides used in the poisoning method include henitrothion, hydramethylthionone, chlorpyrifos, propoxy, and boric acid, and there is a difference in effect depending on which kind of insecticide is used. Most of the domestic marketed insecticides contain henitrothion, hydramethylolone, or chlorpyrifos as effective ingredients. However, since these insecticides mainly paralyze the nervous system of the insect pests, tolerance is generated by passing through the generations, and the effect is deteriorated over time. On the other hand, boric acid is known to have a steady decline in efficacy due to resistance to insecticide compared to other insecticides, because it dissolves the wax layer present in the outer surface of the insect pests and reduces moisture in the body. However, boric acid has a disadvantage that initial insecticidal effect is lower than that of henitrothion, hydramethylolone, and chlorpyrifos.

Patent Document 1 discloses an insecticidal composition capable of increasing the dietary and attractiveness of boric acid by allowing boric acid, sugar, anchovy powder, calcium chloride and water to be homogeneously mixed to maintain the athermal morphology, and a manufacturing method thereof. This insecticide composition is an insecticidal composition capable of maintaining athermal condition without adding boric acid by dissolving boric acid by adding calcium chloride to boric acid. This composition has high dietary and long-term use for easily eating pests, I will bring it.

On the other hand, Hyoscyami Folium is a leaf of Hyoscyamus niger L. (branch and Solanaceae ). It has a peculiar odor and a bitter taste. It contains alkaloids such as (-) - hyosoamine and (-) - atropine, and it is known that it has a painful effect as a toxic plant.

And a step of preparing the monolithic solid material in a ring form.

Another aspect of the present invention provides a method of insecticide comprising the step of placing the insecticidal composition at a place where the pest is moved or inhabited.

Hereinafter, the present invention will be described in more detail.

All technical terms used in the present invention are used in the sense that they are generally understood by those of ordinary skill in the relevant field of the present invention unless otherwise defined. In addition, preferred methods or samples are described in this specification, but similar or equivalent ones are also included in the scope of the present invention. The contents of all publications referred to in this specification are incorporated herein by reference in their entirety.

The inventors of the present invention have studied for the development of an insecticidal composition which can contain insecticidal effect boric acid and can increase the insecticidal effect. As a result, when the boric acid is combined with the hyacinth, And it has an insecticidal effect.

Accordingly, in one aspect, the present invention provides an insecticidal composition comprising a hyphae leaf and boric acid as an effective ingredient.

The ratio of the hygroscopic leaves and boric acid is not particularly limited, but may include, for example, 150 to 250 parts by weight of boric acid per 100 parts by weight of the hyacinth. It was confirmed that the composition for insecticidal use had a synergistic effect (Example 1) by the combination of hyoswice and boric acid, as compared to the case of using each alone. In addition, since the composition for insecticidal use contains boric acid, there is an advantage in that the concern about resistance to insecticidal effect is low even if it is used for a long time. Therefore, the composition is highly preferable in that the insecticidal effect is high and the concern of resistance is low.

The hyphae may be contained in the form of an extract of water, a lower alcohol, or a mixture thereof, but may be preferably included as a powder of hyosyl.

The composition for insecticidal use may further comprise an additional component in addition to hyacinth and boric acid for the production of a formulation for attracting insects and for ease of use. The insecticidal composition according to one embodiment of the present invention comprises 300-500 parts by weight of starch, 250-350 parts by weight of dextrin, 150-250 parts by weight of boric acid, 150-250 parts by weight of glycerin, 150-250 parts by weight of cooking oil, And may have an atherosclerotic morphology.

The term " athermal "as used herein means a semiperipheral solid phase having a degree of hardness such that the mixture forms a ring.

The starch may be any edible starch. For example, the starch may be potato starch, sweet potato starch, corn starch, and the like, but is not limited thereto. Preferably, corn starch may be used as the starch. The starch and dextrin act as food for insects and play an important role in inducing insects and actually ingesting the insecticidal composition.

The glycerin and the cooking oil not only can serve as a binder capable of keeping the insecticide composition in a calyx form, but are also a favorite component of pests including cockroaches. Therefore, glycerin and edible oils also play an important role in attracting insects to actually ingest the insecticidal composition. The glycerin serves especially to keep the insecticide composition moist for a long time. Since the insecticide composition is kept moist by glycerin, the insect pest can be easily ingested, so that the dietary property can be increased.

As the edible oil, any edible oil used for edible oil may be used. For example, soybean oil, okra oil, sunflower oil, grape seed oil, canola oil and the like may be used, but the present invention is not limited thereto. Preferably, soybean oil can be used.

 The composition may have various forms such as a pill, a gel, a liquid, a powder and the like, but most preferably it can be prepared in the form of a ring. If it has a ring shape, it has a wide surface area and is easy to contact with as many pests as possible, so that it has an advantageous insecticidal effect and it is easy to arrange it in a necessary place. In addition, there is an advantage that it can be used neatly because the powder does not blow or the liquid does not permeate. The size of the ring is not particularly limited, but may have a diameter of about 0.3-2 cm, and most preferably about 1 cm, in consideration of ease of use and insecticidal effect.

The pests may be any pests which are readily visible in the environment and known to have an insecticidal effect by boric acid or hyphochine alkaloids. Examples include, but are not limited to, cockroaches, ants, caterpillars, or centipedes.

The insecticidal composition according to the present invention is consumed by one cockroach and dies within 24 hours. However, when one cockroach is consumed after consuming the insecticidal composition, it is divided into other cockroaches and consumed by the other cockroaches It seems to have the effect of killing.

The insecticidal composition according to the present invention comprises

700-1300 parts by weight of water is added to a mixture of 300-500 parts by weight of starch, 250-350 parts by weight of starch, 150-250 parts by weight of boric acid, and 150-250 parts by weight of boric acid based on 100 parts by weight of hyoswice, and water is removed by boiling step;

Dehydrating and drying the residual moisture of the water-removed mixture;

Powdering the dried mixture;

Mixing the powdered mixture with 150 to 250 parts by weight of glycerin and 150 to 250 parts by weight of cooking oil to prepare a sheet-shaped solid; And

And a step of producing the athermal solid form in a ring form.

After the step of boiling and removing moisture, it is preferable to cool to room temperature and then carry out a subsequent process in terms of convenience of operation.

In the dewatering and drying step, the dehydration of the remaining water can be performed by, for example, a method of draining water by removing the moisture-removed mixture from the sieving net. The drying can be carried out by any method as long as the effect of the insecticidal component is not lowered, preferably by a method of natural drying in the shade for about 2 to 5 days.

The pulverizing may be performed by any method capable of pulverizing the dried mixture, for example, by pulverizing the mixture into a pulverizer.

The production of the ring in the ring-forming step can be carried out by any method capable of producing a ring. For example, it may be manufactured using a ventilator, or a person may manually work the ring to manufacture the ring.

The manufacture of the ring according to the above method has the advantage that the insecticidal component and the food component of the insect pests are uniformly mixed with each other, and the insect pests can be mistaken for food as compared with the simple mixture.

According to another aspect of the present invention, there is provided a method of insecticide comprising the step of disposing the insecticidal composition according to the present invention at a place where a pest is moved or inhabited.

Since the insecticidal composition according to one embodiment has a ring shape, the ring is required to be placed at a necessary place compared with the powder form or the liquid form, so that it is very easy to arrange it in a place where a pest is moved or inhabited.

As described above, the composition for insecticidal use comprising the hyphae and boric acid according to the present invention as an effective ingredient has remarkably excellent effects as compared with the case where each ingredient is used alone. In addition, since the composition for insecticidal use further includes an additional ingredient, it is more effective in attracting insects, so that the insecticidal effect can be maximized and the insecticidal composition can be conveniently used while being advantageous in insecticidal effect .
