DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repellent composition and repellent for wild animals which protect planted seedlings and mature trees from animal damage.

[0002]

2. Description of the Related Art Generally used methods include protecting a tree by using some kind of protective material such as a protective net or a protective fence to physically keep an animal from approaching a plant, and a method using a chemical. Examples include cresol, which stimulates olfaction by phenol odor, thiuram-based compound, which stimulates taste, and fragrance, which stimulates mucous membrane and olfaction by mercaptan odor and hydrogen sulfide. All of them are expensive, unfavorable because of harm to the environment, have a sustained effect of about 3 months, and are ineffective, and it is difficult to control the duration, and there is nothing that is practically satisfactory It is.

[0003]

According to the above physical protection method, the wildlife has the inherent ability to learn and to break a protective net or a protective fence, jump over a fence, or dig under a fence. Because of the intrusion, repair and re-installation are difficult, and management is troublesome. Among chemical repellents, fragrances are suitable as they do not pollute the environment, but the duration is short, about half a month, so that once spraying completely removes wild animals completely until seedlings grow. There has been a demand for the development of a repellent with certainty. In order to extend the duration of the repellent, the present inventor uses a liquid polymer compound having an odor that is repelled by animals and chemically stabilizes the compound to maintain the durability. The invention has been completed.

[0004]

In order to solve the above-mentioned problems, a repellent composition for wild animals of the present invention comprises a liquid polymer compound having a sulfur bond in the main chain and having a thiol group at the terminal or at the branched chain end. The gist is that it was used as the main component. Further, the repellent for wild animals of the present invention is characterized in that the liquid polymer compound is supported on a porous substance made of porous silica and granules or fine powders such as synthetic silica, zeolite, diatomaceous earth, and sepiolite. I do. Further, the repellent for wild animals of the present invention is characterized in that the repellent for wild animals carried on the porous material is converted into an aerosol or an emulsion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In general, aromatic functional groups include -SH, -S-, -OH, -O-, -CHO, C
O <, COOH, -COOR, -CO-O-, -NO
_2, -NH2 _, -CN, -NC, -SCN, -NCS, and the like are considered. Examples of the liquid polymer having these functional groups include polysulfide polymer, polybutadiene, acrylonitrile butadiene, and polyphenol. Among the functional groups, mercaptan groups, hydroxyl groups, ammonia groups, phenol groups, and the like are repellent to wild animals and the like, and mercaptan groups and phenol groups are particularly effective. Accordingly, as the liquid polymer having an unpleasant odor of animals, there is a polysulfide polymer having a polyphenol and a mercaptan group, and the latter is preferable because it is chemically stable. In order to use this polymer as a repellent, it is supported on a porous powdery or spherical material such as silica gel as an inhibitor of oxidation of the main component, or is easily mixed with rubber or plastic, or aerosolized. For this purpose, a method such as loading on ultra-fine silica is employed.
In addition, as the porous substance to be supported, other than those described above, inorganic natural and synthetic porous powders such as zeolite, diatomaceous earth, sepiolite, and starch, cellulose, and the like, which have been processed and made porous, can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First to fifth embodiments of the present invention will be described with reference to Table 1. Planted 96 cypress and cedar seedlings (about 30 cm) at intervals of 1.8 m in 96 parts of a plantation in Hyogo prefecture where wild animals (especially Japanese deer, bears, and rabbits) are severely damaged, and 16 trees Each block was divided into blocks, and each block was sprayed with a repellent by a different method as described in the following Examples and Table 1, and an experiment was performed to confirm the effect after a certain period of time. As a result, useful results were obtained in each method, and will be described in detail below. The liquid diethoxymethane polysulfide polymer used in the examples has a chemical formula of HS- (C _{2
H 4 -O-CH 2 -O- C} 2 H 4 -S-S-) n-C 2 H 4 -O-CH 2 -O-
Represented by C ₂ H ₄ -SH. [Example 1] 40 g of liquid diethoxymethane polysulfide polymer was impregnated into 100 g of silica gel having a particle size of 40-8-Mesh, and 100 g of the powder was sprayed on the root of a seedling (block 2). As a result, as shown in Table 1, the block 1 of the comparative example, which did not perform any processing, lost most of its branches and leaves after six months, and in the present example, it had lost one month after one month. In the same manner as in the untreated comparative example, damage was observed on the top and some of the upper branches and leaves, but at 6 months, the upper leaves were eaten but the lower part was safe, and 1 month.
Even after the years had passed, the upper branches were completely absent, and the lower section was safe. In general, seedlings of about 30 cm can reach 20
It is understood that the effect of the repellent has been extended to about 25 cm from the place of spraying for more than one year by spraying the silica gel impregnated with liquid diethoxymethane polysulfide polymer to the root of the tree because it grows about cm. . [Example 2] 100 g of a spherical B-type silica gel impregnated with 40 g of liquid diethoxymethane polysulfide polymer was sprayed on the root of a seedling (100 g) (Block 3). This result shows that the same effect as in Example 1 was observed, regardless of whether it was powdery silica gel or spherical silica gel,
As shown in Table 1, for about one year longer than in the comparative example where no treatment was performed, the branches and leaves about 25 cm from the spraying site were not damaged by wild animals and helped to protect the seedlings. found. Example 3 An aerosol was obtained by impregnating 100 g of ultrafine powdered silica having an average particle diameter of 1.4 nm with 40 g of liquid diethoxymethane polysulfide polymer. It was sprayed on the leaves, centering on the top of the seedlings (Block 4). As a result, as shown in Table 1, compared to the case where the seedlings were sprayed on the roots of the seedlings as shown in Examples 1 and 2, there was no damage to the seedlings even after one year, and a very effective effect was observed. . By sprinkling on the leaves of the seedlings, sprout may be generated, and even if the sprout is not sprayed with the chemical, the sprout of the above Examples 1 to 2
As seen in the above, since the effect lasts within about 25 cm around the spraying agent, it seems that it is possible to prevent a wild animal from approaching a sprout. In addition, the composition of the present invention has a chemically stable polymer compound supported on a porous substance such as silica, and since the repellent does not directly contact the tree, it does not harm the seedling itself, It does not adversely affect growth. In the experiment, growth of about 20 cm was observed in one year. Example 4 50 g of constarch was mixed with 750 ml of water, heated to 100 ° C. and gelatinized, and then 40 g of liquid diethoxymethane polysulfide polymer was added to 100 g of ultrafine silica powder having an average particle diameter of 1.4 nm. 200 g of the freshly dipped one was dispersed to form an emulsion. The seedlings were immersed and planted (block 5). As a result, as shown in Table 1, as compared with the case where the seedling was sprayed at the root of the seedling as shown in Examples 1 and 2 as in Example 3,
There was no damage to the seedlings even after years, and a very effective effect was observed. Also in this case, by sprinkling on the leaves of the seedlings, even if sprout comes out and the drug is not sprayed on the sprout, as shown in Examples 1 and 2 above, 25 c around the sprayed drug
Since the effect lasts within m, it seems that the wild animals can be prevented from approaching the shoots. It goes without saying that the composition of the present invention does not harm the seedling itself. Example 5 40 g of liquid diethoxymethane polysulfide polymer impregnated with 100 g of ultrafine silica powder having an average particle diameter of 1.4 nm was mixed with 30 g of polyethylene 100.
g and melt-mixed to form a film. Four iron poles were built around the saplings to surround the saplings, and the film of the present example was wound therearound to surround the saplings (block 6). As a result, as shown in Table 1, as in Examples 3 and 4, at any stage after planting, and at any place of the seedling,
No harm was found, and it was preferable as a repellent. In addition, since Examples 3 and 4 are both ultrafine powders having a nearly spherical shape, they can penetrate deep into the microaerosols of the branches and leaves, and in Example 5, they are integrated with the resin. It does not splatter or spill and contaminate soils and rivers.

Example 6 30 g of 40 g of liquid diethoxymethane polysulfide polymer impregnated with 100 g of ultrafine silica powder having an average particle diameter of 1.4 nm was melt-mixed with 100 g of polyethylene to form a tape. The tape of this example was wound around the trunk of the adult tree to protect the trunk of the adult tree, and observation was performed for one year. In general, in the case of an adult tree, Kamokashi etc. use the trunk of the tree to sharpen the corners, so the bark of the trunk is peeled off, and the damage caused by the wounded round bud is noticeable, but in this example, As in Examples 3 to 5, at any stage after the observation, no damage or peeling due to corners was observed in the stem, which was preferable as a repellent. Also, as in the other examples described above, no problems with trees and the environment were recognized.

As described above, the repellent composition and repellent for wild animals of the present invention are harmless to the human body, wild animals and trees, and are planted seedlings and adult trees such as cedars and cypresses. Does not hinder growth. Also, from the root to the tip, it can be completely protected from wild animal damage or horn damage for one year. In addition, powder, spherical, aerosol, emulsified, film, and tape forms can be selected as necessary, which can contribute to work efficiency, workability, cost effectiveness, and the like. And
The compositions and repellents of the present invention have obtained very effective results such that the prevention of food damage is almost complete even after one year has passed, and many plantations that are now seriously damaged It is expected to be adopted as a groundbreaking measure on site.
