JP2018100251A - Evasion method of bear and evasion agent - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an evasion agent containing evasion effective components that are less expensive, do not cause environmental contamination, do not impart stimulation to human bodies, and do not impart unpleasant feeling such as bad odor.SOLUTION: When a part close to a calyx of a raw eggplant is microparticulated into 5 micrometer or smaller at low temperatures, an evasion effective substance of bears can be obtained. Furthermore, when kernels, twigs, and leaves of raw shikimic are processed at low temperatures as fine particles of 5 micrometer or smaller, an evasion effective agent can be obtained. When these are gelated at low temperatures to control volatilization of effective evasion components, these can be used as the sustainable evasion agent.SELECTED DRAWING: None

Description

The present invention relates to a bear repellent method and a repellent, and is capable of promptly and continuously providing a repellent effect excellent in safety without polluting the environment and crops such as vegetables with harmful substances and without harming the human body. Further, the present invention relates to a repellent method and a repellent provided at a low cost.

In recent years, there have been frequent accidents involving harvesting of edible wild plants in mountain forests and mountain stream fishing by bears, causing damage to an average of more than a dozen people a year. The damage of crops caused by bears is said to be as high as 800 million yen in the year of bad harvest. In the hilly and mountainous areas, it is dangerous to live up to the human sphere. There have been various ways to repel bears. From the old days, there are various ways to make a sound so as not to meet bears, to generate light and drive it away. Various measures such as spraying are taken.

However, none of these methods has a certain repellent effect, and the initial cost of protective fences, ultrasonic devices, light emitting equipment, etc. is considerably high. Although there are chemicals that are generally regarded as pest repellents, it is not clear whether they are small animal subjects or are mainly repellents for deer and wild boar and bears have a repellent effect. Also, because people have a bad odor, they can't carry bears. There are repellents made from herbal medicines, but they are expensive because they are raw materials.

It is most required not to decompose repellent active ingredients such as enzymes in the process of producing the repellent. As in existing processing methods, active ingredients are decomposed in steps such as dissolution by boiling and alcohol extraction, and only repellents with low effects can be obtained.

In order to enable low-temperature extraction, cell membranes of raw materials to be used must be physically pulverized one by one to extract the active ingredients.

Natural materials that are free from environmental pollution, do not inhibit crop growth, have no impact on the human body, and have no bad odor and must be used at low cost.

The product repellent must be capable of long-term use for several months, so the volatilization of ingredients must be slow.

A form that can be carried during outdoor activities such as harvesting wild plants and mountain stream fishing and that can be used for a long time in farmland is also required.

In order to extract the active ingredient, the cell membrane of the raw material must be destroyed at a low temperature to 5 microns or less. Raw eggplant seeds including raw material were cut into upper 3/2 parts as a raw material, and a millstone according to the invention of Takeshi Yuzawa, one of the applicants of the present application (using a millstone for producing a powder litchi and its millstone) According to the method for producing a powder litchi, the powder is crushed into particles of 5 microns or less in an unheated state. In general, when such pulverization is performed, lyophilization is performed. However, since the active ingredient of the repellent is decomposed even by a temperature increase due to heat of vaporization of lyophilization, other methods than the above are impossible.

As an alternative to eggplant as a raw material, an effective bear repellent active ingredient can be obtained even if shikimi is used. The parts of shikimi used are fruit, branches and leaves in a raw state, and those which have been roughened with a mixer are pulverized to 5 microns or less with the above-mentioned stone mortar.

Separately, agar derived from Tengusa is prepared and lowered to a temperature that does not decompose the active ingredient of the repellent active ingredient in a non-gelled sol state (the temperature varies depending on the agar product at approximately 40 ° C or higher). Mix with this. After pouring into a small container in the state of the sol, it is cooled and gelled to obtain a product.

The container is a rectangular parallelepiped having a depth of 2 cm, a length of 5 cm, and a width of 6 cm and a capacity of 60 ml, and filled with agar. The inner cover or inner bag of a synthetic resin film with many fine needle holes to prevent the active ingredient and repelling of moisture from the gel agar and the container covers the agar. Remove the lid before use. A string is attached to the container so that it is easy to use outdoors or carry.

Because it contains enough repellent active ingredients that bears don't acclimatize, it has immediate effects and is durable. Moreover, since 60 ml per box covers a radius of 30 m for 6 months, a relatively small amount of repellent is used around fields and houses. It is easy and safe to carry to mountains and other places, is harmless to the human body, has no foul odor, and does not give off discomfort.

As a preventive measure during the season when bears appear, hang this repellent with open lids around living areas, field farms and apiaries at intervals of 30 meters, and to areas where bears are expected to appear. Carry this repellent with the outer lid open when you go out.

Claims (3)

Raw eggplant is cut into two-thirds of the upper part of the eggplant using a spatula and crushed into fine particles of 5 microns or less in a non-heated state with a special stone mortar. A bear repellent gelled after mixing in a heated state (40 ° C. to 58 ° C.). Shikimi fruits, branches, and leaves are crushed into fine particles of 5 microns or less with the above-mentioned stone mill in an unheated state, and the repellent active ingredient is not decomposed into the gel-like agar derived from the Japanese aphid (40 ℃ to 58 ℃) ) Bear repellent gelled after mixing. It is a container that can be sealed with a lid or bag of many synthetic resin films with needle holes to suppress the volatilization of active ingredients and moisture from gelled agar containing bear repellent active ingredients at a certain level, A container with a string attached so that a person can carry it while walking or be hung outdoors.
