Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bird and insect repellent for protecting agricultural crops and horticultural crops from damage caused by birds and insects, and a bird and insect repellent using the bird and insect repellent. It's about the ingredients.

[Conventional technology] Vegetables such as cabbage, radish, and corn, cherries,
Agricultural products such as fruits such as grapes, grains, and various garden plants are at risk of being damaged by pests including crows, birds such as bulbuls, and diamondback moths from the germination and growth period to the harvest period. To prevent this, nets may be set up around fields or pesticides may be sprayed.

In general households, insect repellents for clothing containing naphthalene and paradichlorobenzene as main ingredients are widely used.

These insect repellents volatilize and sublimate, emitting odors that are repellent to insect pests that stick to clothing, thereby providing an insect repellent effect. Naphthalene, baladichlorbenzene, etc. have strong sublimation properties and sublimate and dissipate in an open space in a short period of time, so they are usually used in closed spaces such as chests of drawers and are not used in agriculture that targets the outdoors. Ta.

[Problem to be solved by the invention] In agriculture, it is virtually impossible to completely cover a vast field with the method of setting up bird nets for the purpose of preventing birds from entering. It can be said that it is extremely unreasonable from the point of view of expenses and labor involved. Moreover, bird nets are not necessarily a foolproof means and cannot reliably prevent birds or other small animals from entering.

Furthermore, the method of preventing insect damage by spraying pesticides requires equipment such as pesticide spraying equipment, and furthermore, spraying pesticides requires a great deal of labor and cost.

Furthermore, chemical damage caused by residual pesticides is also a serious problem.

Considering the possibility of reusing clothing insect repellents containing naphthalene, paradichlorobenzene, etc. as main ingredients, which are used in general households, for agricultural purposes, the odors evaporated from these household clothing insect repellents are likely to be caused by insects and insects. Birds dislike them, and although there is no risk of causing chemical damage, they are not practical for agricultural or horticultural purposes.The reason is that these insect repellents have strong sublimation properties.
This is because in an open space, it quickly evaporates, sublimates and disappears.

In other words, large amounts of insect repellent are required to continuously emit odors that are repellent to crows and small insects over a relatively long period of time.
It is impractical in terms of cost and ease of handling alone.

However, the present invention has been made by focusing on the above-mentioned conventional problems, and it is possible to maintain birds and birds for a relatively long period at low cost.
A bird and insect repellent for agriculture and horticulture that repels insects, effectively prevents damage to agricultural and horticultural crops by insects, and does not cause problems such as chemical damage caused by residual pesticides, as well as an easy-to-handle bird repellent using the same. The purpose is to provide insect repellent equipment.

[Means for Solving the Problems] In order to achieve the above object, the bird and insect repellent according to the present invention has the following features:
It is made by mixing paradichlorobenzene with at least one component selected from petroleum resin, polybutadiene, and mercaptan.

It is preferable to mix pumice or diatomaceous earth with the above bird and insect repellent.

In addition, the bird and insect repellent according to the present invention includes a bird and insect repellent made by mixing paradichlorobenzene with at least one component of petroleum resin, polybutadiene, and mercaptan.
It is sealed in a container with many ventilation holes.

The above-mentioned container for enclosing the bird and insect repellent may be formed by joining sheet materials having a large number of ventilation holes into a bag shape, and a hanging means may be attached to a part of the periphery.6 [Function] Bird and insect repellent material Baladichlorbenzene, the main ingredient, emits an odor that is repellent to birds, insects, and other insects when it evaporates and sublimates. Balajichlorbenzene is water insoluble;
Since it changes from a solid to a gas without sublimating, that is, passing through a liquid phase, it will not be eluted by rainwater or the like, and therefore will not cause any adverse effects such as chemical residue on field crops.

The petroleum-based resin mixed with the above-mentioned main component is in the form of water-insoluble small particles, and is recognized to have the property of suppressing the rapid sublimation of baladichlorbenzene. Therefore, paradichlorobenzene, which is the main component of the bird and insect repellent, continues to have a bird and insect repellent effect for a relatively long period of time even in small amounts.

By mixing pumice or diatomaceous earth with the bird/insect repellent, the bird/insect repellent can maintain even volatility evenly while suppressing its sublimation.

Furthermore, by enclosing the bird and insect repellent in a container with many ventilation holes, it will not undergo chemical changes that would reduce its effectiveness due to exposure to direct sunlight or erosion from rainwater. On the other hand, while protecting the bird and insect repellent contained within for a long period of time, the bird and insect repellent sublimates at a moderate rate and releases the odor that birds and insects dislike through the ventilation hole of the container, creating a good volatilization state. In addition, it improves portability and makes handling easier. This container is formed by joining sheet materials with many ventilation holes into a bag shape, and by attaching a hanging means to a part of the periphery, it can be easily handled when installed near an outdoor field. can.

[Example] The present invention relates to a bird and insect repellent for agriculture and horticulture that is mainly composed of baladichlorbenzene, which emits an odor that horse owners dislike due to volatilization and sublimation, and is designed to withstand long-term use outdoors. It is characterized by slow sublimation.

Components that suppress the sublimation rate of valadiclorbenzene include petroleum resins, polybutadiene, and mercaptan.

Petroleum-based resins are rubber additives made by polymerizing by-product oil to form resins, and include polymers of butane or hebutane.

As the mercaptan, polymercaptan, t-mercaptan, etc. can be used.

The combination and blending ratio of the above-mentioned valadiclorbenzene, petroleum resin, polybutadiene, etc. are determined depending on the target individual for bird and insect control, the location where the bird and insect repellent is installed, and are not particularly limited.

Normally, valadiclorbenzene sublimes in a short period of time, but the volatilization time is extended by mixing petroleum resin, polybutadiene, and mercaptan.

If diatomaceous earth or pumice is appropriately mixed with the above-mentioned bird and insect repellent according to the present invention, the sublimation of the bird and insect repellent becomes more gradual. That is, the crystal particles of the bird and insect repellent come into contact with or are coated with diatomaceous earth, reducing the volatilization area and reducing the sublimation rate. Since diatomaceous earth and pumice are originally porous, even if they completely cover the entire crystal grains of the bird and insect repellent, or suppress the sublimation of the bird and insect repellent, this will not be hindered.

The container for storing the bird and insect repellent described above may be a plastic cylindrical container 11 as shown in FIG. 1, or a bag-like container 21 made of a resin sheet such as polyethylene as shown in FIG. 2. .

That is, as shown in FIG. 1, a cylindrical container 11 has a large number of small ventilation holes 13 all over its circumferential surface, and the bird and insect repellent 1 is sealed therein to constitute a bird and insect repellent device 10. It is preferable to attach a hanging means 17 such as a string to the upper surface 15 of the cylindrical container 11.

The bag-like container 21 of the other bird/insect repellent 20 is made of a resin sheet material 21' which is folded in half with the bird/insect repellent 1 interposed therebetween, as shown by the imaginary line in FIG. Combine, 3
Seal the edges by heat welding. A large number of small ventilation holes 23 are formed in at least other parts of the seal part 25 at the periphery. A hanging means 27 is also attached to this container 21, but when the seal part 25 is welded, it is placed between the sheet materials 21'. By inserting a ring-shaped suspension means 27 made of synthetic resin, adhesive formation can be easily performed. Of course, the suspension means may be simply provided with a suspension hole 27' in the seal portion 25.

The illustrated storage container 11.21 for the bird and insect repellent l is one means for putting the bird and insect repellent according to the present invention into practical use, and the structure of the container is not particularly limited.

Next, an experiment conducted to prove the effectiveness of the bird and insect repellent of the present invention will be described.

This experiment was carried out from April 21, 1990 to May 15, 1990 in a radish and turnip field (area: 1156 m) at 243 Yamate-cho, Naka-ku, Yokohama, Kanagawa Prefecture.

The experimental method involved dividing the field in which the experiment was conducted into seven approximately equal rectangular sections, into which 6 sections were divided into 6 sections using each of the 6 types of bird and insect repellents shown in the experimental examples below. The four sides of the divided plots were fenced off, and no bird and insect repellent was installed in the remaining one plot.

Each divided plot was separated by an appropriate distance so as not to be affected by the bird and insect repellent placed in the adjacent plot.

The installation mode of the bird and insect repellent according to the present invention is as follows.

Bird and insect repellent 1 obtained by mixing the components set in each of the following six experimental examples was sealed in a bag-shaped container 21 made of polyethylene shown in FIG. 2 to construct a bird and insect repellent 20. As shown in FIG. 3, this bird and insect repellent device 20 was suspended using a hanging means 27 from a string S passed between two pillars P driven into the ground.

This bird/insect repellent tool 20 is used for four
It was placed approximately in the center of each side. In other words, the target field was surrounded with four types of bird and insect repellent equipment.

A total of 40 radishes and turnips were planted in each divided plot, and damage to the leaves of the crops by horse owners was observed throughout the experimental period. The degree of feeding damage is classified as A (no feeding damage), B (slight feeding damage), and C (
Evaluation was made using a 3-rank scale (with a considerable amount of feeding damage).

(Comparative example) When we observed feeding damage to radish and turnips planted in the assigned plots under almost the same conditions as the six experimental examples above, we found that
A considerable amount of feeding damage was observed from Sun Moon. The feeding damage rating is C.

Table 1 shows the bird and insect prevention effects of Experimental Examples 1 to 6 above, along with comparative examples.
Shown below.

Table 1 (Evaluation of feeding damage) Evaluation rank A: No feeding damage B1 Some feeding damage C: Considerable amount of feeding damage The bird and insect repellent according to the present invention showed not only an insecticidal effect but also an insecticidal effect on diamondback moths. .

It also showed a particularly remarkable bird-preventing effect against crows and bulbuls.

(Effects of the Invention) As explained above, the bird and insect repellent of the present invention contains at least 1 of petroleum resin, polybutadiene, and mercaptan, in addition to baladiclorbenzene, which has an odor that horse owners dislike.
By mixing the ingredients, it is possible to slow down the sublimation of paradichlorbenzene, which originally sublimates and evaporates rapidly, so it is possible to produce bird and insect repellent effects over a relatively long period of time in outdoor fields. . Therefore, it can be an effective means for preventing birds and insects in place of conventional bird nets which have insufficient bird and insect repellent ability and are troublesome to handle. In addition, the above ingredients that make up the bird and insect repellent are water-insoluble and completely dissipate by sublimation, so they do not cause chemical damage to crops, etc., and are extremely safe compared to conventional insect repellent methods that involve spraying pesticides. It is. Furthermore, by mixing pumice or diatomaceous earth, the bird and insect repellent effects can be sustained more slowly, so even when applied to vast farmlands, bird and insect control management can be carried out very easily and at low cost.

Furthermore, by sealing it in a container with many ventilation holes, it is easy to handle, and it is also protected from chemical changes that would reduce its effectiveness due to exposure to direct sunlight or erosion from rainwater. It can protect birds with insect repellent, etc.
It is possible to provide a bird and insect repellent device that is highly practical and highly effective.
