JPH029806A - Vermin-controlling member - Google Patents

Abstract

PURPOSE:To obtain the subject member having long action and free from environmental pollution by using at least one substance selected from verdigris and natural rubber disliked by ant and slug and forming the substance in the form of a band or tape which can be attached to the stalk or twig of a plant to be protected from the damage. CONSTITUTION:The objective vermin-controlling member is made of at least one material selected from copper or a copper alloy generating verdigris (disliked by slug) and natural rubber material (disliked by ant). A slug-controlling member can be produced by attaching copper or a copper alloy (preferably its fine powder) to a main body of a tape and applying a tacky adhesive layer to the tape main body. As an alternative, a vermin-controlling member is produced by forming a tape main body with a natural rubber material mixed with fine powder of copper or copper alloy or arranging one or more copper wires on the main body of a natural rubber tape in the longitudinal direction of the tape. The tape is attached to the circumference of the stalk, twig or pot of the plant to be protected.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of organisms that cause damage to agricultural crops and garden plants, or that indirectly harm them by helping them survive. In particular, the present invention relates to a pest control member that is effective in protecting crops from slugs, ants, and the like.

[Conventional technology]

BACKGROUND ART Various pests cause damage to agricultural crops, garden plants, etc. by eating the leaves and fruits, and transmitting infectious viruses and bacteria. For this reason, various chemicals are used to exterminate these pests.

An example of this is damage caused by ants. Ants rarely cause the above-mentioned damage directly to plants, and are generally not recognized as pests to plants; however, by coexisting with aphids, they help the aphids survive and indirectly damage plants. Become. That is, aphids attach in large numbers especially to the shoots of plants and inhibit the growth of plants, but ants indirectly cause damage to plants by helping the aphids survive.

Next, slugs damage plants by scraping them off with their file-like tongues, causing damage such as weakening crops and significantly reducing their commercial value.

[Problem to be solved by the invention]

As described above, both ants and slugs are known to cause direct and indirect damage to plants, but their extermination is not always sufficient. Although slugs are not insects, for convenience of explanation below, unless otherwise specified, they will be included in the term "pests".

The reason why ants and slugs cannot be adequately exterminated is the same as in the extermination of other pests, and it is necessary to ensure that no substances that are harmful to the human body remain on the crops. , it is difficult to use highly insecticidal drugs. Next, ants usually make nests underground, and only a portion of the total number of ants, such as worker ants, come out of the nest and become active, so even if strong chemicals are used, all of them cannot be killed. That is extremely difficult.

The damage caused by slugs is direct; for example, when cultivating mushrooms outdoors, such as shiitake cultivation, the growth environment for mushrooms is a low light and humid environment, which is extremely conducive to slug activity. Due to the favorable environment, a considerable number of mushrooms are damaged by slugs. In addition, fruit trees are seriously damaged; for example, many trees such as peaches are eaten, and the commercial value of the damaged trees is significantly reduced.

In the case of slugs, unlike many other pests, they are active at night, and during the day they hide behind dead leaves and objects, so it is not easy to find them, and even if they are found, they are not found during the day. The number of solids that can be produced is only a small fraction of the total number of solids. Therefore, it is also very difficult to capture all solid slugs. In view of this difficulty in exterminating slugs, repellents that attract slugs have been provided.

This repellent is used to exterminate slugs by spraying them in areas where they are likely to appear. In other words, slugs are attracted to the sprayed pesticide, and when they eat the pesticide, they die. This method can kill a considerable number of slugs, which are normally difficult to detect, and is a fairly effective method, but it is not attracted to all solids, and the persistence of the agent is low, so it takes a long time. As time passes, the number of slugs increases again and their activity becomes more active. For this reason, it is necessary to use pesticides frequently, and when used over a wide area, the amount used becomes enormous, making it uneconomical. Also, a considerable amount of manpower is required to spray the pesticides, making it difficult to find a practical solution. It can hardly be called a means.

[Background of the invention]

The present invention has been constructed in view of the above problems, but in this case, before explaining its contents, it is effective for understanding the invention to explain the circumstances that led to the invention. think.

As explained in the section of the problem to be solved by the invention, it is expected that it will be very difficult and economical to catch and kill ants and slugs to the extent that they can eliminate their damage. Furthermore, even if these pests can be exterminated to the desired extent,
The use of large quantities of insecticides and pesticides is dangerous in itself, and there is a great possibility of environmental destruction and adverse effects on the human body. For this reason, the applicants, etc., recognize that there is a fundamental problem with the conventional method of protecting crops from damage by these pests by trapping and exterminating the ants and slugs mentioned above, and therefore, the applicant et al. Instead, they decided to develop a method that would prevent them from getting close to the object.

Based on this recognition, we first conducted various tests to find substances that ants and slugs dislike, that is, substances that do not have the ability to kill ants and slugs, but have properties that prevent these pests from approaching. .

As a result of the above, first, ants dislike natural rubber, so when rubber tape made of natural rubber was wrapped around the stem of a plant, there were no ants above the area where the rubber tape was wrapped. In addition, for comparison with natural rubber, tests were conducted using tapes made of various synthetic rubbers, but these synthetic rubber tapes were unable to deter ants at all, and many ants were found above the area where the rubber tape was wrapped. It was observed that there was a clear difference between natural rubber and synthetic rubber in terms of preventing the entry of ants.

It was also confirmed that copper, especially copper with a patina, is extremely effective against slugs, and that slugs do not come near it at all.

When we captured a large number of slugs and placed them in a petri dish, we put a patinated copper piece in one petri dish and left the other dish empty. During this time, all the slugs left the piece of copper, and no more slugs came near it. In the other petri dish, the slugs were almost dispersed, and no unusual situation occurred. In addition, I tried forcing the slug to come into contact with the verdigris (1), and tried to make its body extremely small to escape from the piece of copper, but this did not cause the slug to die. In this way, it was discovered that slugs have a strong aversion to patina.

The present invention was constructed based on the above-mentioned tests and recognition.

It should be noted that although the fact that patina is poisonous or extremely poisonous has been widely spread for a long time, it is non-toxic to the human body, and this point will be explained in the examples.

[Means to solve the problem]

The present invention is constructed to solve the problems of the prior art based on the above recognition. In other words, considering that ants and slugs are unable to fly in the air unlike other pests, at least one of the above substances that these ants and slugs dislike may cause damage to the stems and stems of the plants they damage. Form a band or tape-like material that can be attached to the target plant as a pest control member, and use this pest control member to attach to the stems of the target plants,
In some cases, it is configured to be attached around a pot, etc., thereby preventing these pests from climbing above the pest control member attachment part, thereby protecting the damaged object from these pests.

[Effect]

The advancement of these ants and slugs is prevented by the natural rubber that ants dislike and the member that has developed a patina that slugs dislike, thereby protecting the object from these pests.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows a configuration in which a pest control member (hereinafter simply referred to as "control member") is formed into a tape shape. Figures 2, 3, and 5 are cross sections of this tape-like member (A-A in Figure 1).
An example of the configuration of the tape in the cross section taken at ``+t%'' is shown.

First, Fig. 1 shows the general structure of a tape-like pest control member. The tape T consists of an adhesive layer T1 and a tape body made of a material that is disliked by ants and/or slugs. For example, a long tape as shown in the figure is used. After winding the tape and cutting it to the desired length, peel off the anti-adhesive tape T2 coated with wax or the like to expose the adhesive layer T, and use this tape by pasting it on a predetermined location. .

FIG. 2 shows a first configuration of the tape-like pest control member.

Reference numeral 1 denotes a tape body made of thinly stretched copper, and an adhesive layer 2 is formed on the tape body 1, which is a so-called metal tape. In the case of this tape, patina is generated after it is attached to an object by a method described later, but the tape body may be made of copper with patina generated on its surface in advance. Since the present invention utilizes the effect of patina, any metal that generates patina may be used, and therefore includes not only pure copper but also copper-based alloys that generate patina. Hereinafter, when "copper" is simply referred to, "copper-based alloy" is also included.

FIGS. 3 and 4 show a second configuration.

Reference numeral 3 in the figure is a tape body, which is made of various synthetic resins. 4 is an adhesive layer for sticking this tape to a predetermined location. Another adhesive layer 5 made of an adhesive material is formed on the surface of the tape body 3 opposite to the surface on which the adhesive layer is formed, and this adhesive layer 5 is coated with copper. Fine powder 6 is adhered to the entire surface, forming a fine powder copper layer. In the illustrated configuration, the fine powder steel is attached using an adhesive, but the method is not limited to this. For example, it may be attached by thermocompression bonding to a tape body made of synthetic resin, or it may be attached using an adhesive-like adhesive. Possible methods include attaching it with a material. In short, it does not matter how the fine copper powder 6 is attached to the tape body 3.

The above has explained the structure of a member mainly intended to protect slugs by copper and the formation of patina on copper, but the structure shown in Figures 5 and 6 below is effective against both ants and slugs. This shows the configuration of the typical members.

First, the configuration shown in FIG. 5 will be explained.

7 indicates the tape body. This tape body is made of a material whose main component is natural rubber, and the tape body is formed by adding and mixing fine copper powder into this material. Applicants have measured the strength and found that it is approximately 50% stronger than the natural rubber material used to form the tape.
It was confirmed that even if approximately % by weight of fine copper powder was added, the strength was sufficient for practical use. Note that natural rubber here broadly refers to rubber products whose main raw material is natural resin extracted from rubber trees, which can be molded into the tapes and the like by vulcanization or the like. In the structure shown in FIG. 5, fine copper powder is added to natural rubber, which is disliked by ants, as a base, so if it is left in the natural environment, it will develop a patina, making it possible to deter both ants and slugs. Note that reference numeral 8 is an adhesive layer for pasting this tape body.

FIG. 6 shows yet another configuration.

9 is a tape formed from a material whose main component is natural rubber, and 10 is a tape 9 formed in the longitudinal direction of the tape 9.
It is a copper wire arranged so as to be integrated with the In the case of this configuration, the tape can be attached to the trunk or trunk of a plant by tearing the tape or the like, so it is not necessarily necessary to form an adhesive layer for attaching the tape. Even in this configuration, both slugs and ants can be deterred by the patina and natural rubber generated on the copper wire 10.

FIG. 7 shows a tape made of natural rubber with fine copper powder added into a ring shape, so that it can be easily attached to flower pots and logs for cultivating shiitake mushrooms.

In the case of this configuration, it is preferable to form rubber rings with several diameters depending on the diameter of the object to be attached.

Furthermore, the patina used to repel slugs has long been considered to be poisonous, and there are concerns that the structure in question, which uses this patina, may have an adverse effect on the human body if touched during handling, and that water, etc. There is also a possibility that crops may become toxic due to their absorption of the dissolved patina, so this point will be explained below.

It has long been said that patina, a basic compound of copper, is toxic, but there are many misunderstandings and prejudices about it, and in reality, it is almost impossible to say that patina is harmful to humans. .

There is a research report on this point, which I will introduce below.

In other words, Mr. Toyoyo, a former professor at the University of Tokyo School of Medicine and an authority on hygiene, conducted hygienic research on copper for three years starting in 1960, and concluded that patina was not poisonous. ing. According to his test results, patina is completely insoluble in water or hot water, and therefore cannot be absorbed orally into the body. Even if a patina mass were to enter the stomach, the patina irritates the gastric mucosa and causes emesis, resulting in vomiting before it can be absorbed into the body. In fact, in his animal experiments, the patina was completely insoluble in water, making it difficult for experimental animals to absorb it.In the end, he crushed the patina into a powder and suspended it in a 2% gum arabic solution. The patient had no choice but to forcibly administer the solution orally using a probe. (Source: ``Copper and Sanitation'' magazine, Japan Research Center) As mentioned above, there is an extreme misunderstanding about the toxicity that has traditionally been said about patina, and it can be thought that it is actually non-toxic. Here, the reason why slugs dislike this kind of patina is that it is clear that it acts as an irritant to living organisms, such as irritating the gastric mucosa, as shown in the experimental example above. I think that patina as a material is something that slugs dislike. Therefore, in this configuration, it cannot be expected to have the effect of killing or injuring slugs, and the purpose is to prevent slugs from approaching the object.

It is thought that the reason why ants dislike natural rubber is that when natural rubber is detected by the sense of smell or other senses, it is perceived by ants as a kind of irritant that they dislike.

Next, an example of use of the above-mentioned protective member will be explained.

FIG. 8 shows an example in which the present protective member is used to protect against slugs during shiitake mushroom cultivation.

At the base of the log 12 there are two tape-shaped protective members shown in Figure 1.
It can be installed by winding it in stages. If the surface of this tape T has a patina in advance or is made of copper without patina, then the tape T can be attached to the log afterward. Leave it for a certain period of time to develop a patina.

Slugs mainly climb logs 12 and shiitake mushrooms 13 at night.
However, the shiitake mushroom 13 is protected from damage by the slug because it is blocked by the protective member that has developed a patina and cannot move forward any further.

In addition, in the case of raw wood, a ring-shaped protection member 11 as shown in FIG. 7 may be attached.

FIG. 9 shows a state in which the protective member is attached to a fruit tree.

For example, since peaches and the like are seriously damaged by slugs and aphids during the growth of new shoots, tape-shaped protective members T are attached to several locations such as the tree trunk 14 and the tree trunk. In this case, in order to protect both ants and slugs, the protective member is a combination of natural rubber and copper (patina) as shown in FIGS. 3, 5, and 6. Although slug control has a direct effect of preventing feeding damage, ant control has the main indirect effect of eliminating aphid damage by inhibiting the survival of aphids that coexist with ants.

Next, the bactericidal effect of copper itself has been proven through tests and research, so the bactericidal effect can be exerted when water containing copper ions flows due to rain, etc. Furthermore, copper is one of the trace elements necessary for plants, and its supply is useful for plant growth, so it is expected that installing this protective member will have positive results for plant growth. .

That is, when considering the effect of copper on plants by looking at the symptoms of plants when copper is deficient, the following symptoms have been reported when copper is deficient.

(a) Growth is stunted and the leaves become curly and yellow or white.

(b) Root development becomes poor.

(c) For cereals, yields decrease.

(d) Seeds do not germinate.

(e) reduced resistance to diseases and parasites;

As described above, by using the present pest control member, in addition to controlling pests, it can also be expected to have the effect of preventing the occurrence of copper deficiency in plants to be controlled and promoting healthy growth of plants.

FIG. 10 shows a state in which the tape-shaped protective member shown in FIG. 6 is attached to the stem of a relatively small plant.

In this case, by twisting the joint of the tape after attaching the protective member to the stem 1'4, the protective member can be easily attached to the stem by twisting the copper wire 10. Therefore, similar to the configuration shown in FIG. 7, no adhesive is required.

FIG. 11 shows a state in which the pest control member is attached to the flowerpot 15. When used in a flowerpot, in addition to the tape-like protective member, an annular pest control member 11 shown in FIG. 7 can be used. Slugs usually hide behind the flower pot 15 during the day and crawl out at night and damage the plants 17, so if you attach the control member T or 11 to the body of the flower pot 15, you can prevent damage from slugs. can.

〔effect〕

As described in detail above, the present invention uses at least one of patina and natural rubber, which are disliked by ants and slugs, and can be attached to the stems of plants, etc., which are the targets of damage. A band-like or tape-like material is formed to serve as a pest control member, and the pest control member is configured to be attached to the stem or stem of the target plant, or around the pot in some cases. By configuring the structure to prevent these pests from climbing onto the structure, damage to agricultural crops, garden crops, etc. can be effectively prevented.

Furthermore, it does not cause any environmental damage such as that caused by spraying insecticides, and is extremely safe.

Furthermore, the effects of natural rubber and patina are long-lasting, and in particular, the effect of patina is semi-permanent, so it is possible to maintain a high pesticidal effect over a long period of time, and other major effects can be exerted.
