Description

Pest control tree guards {TRAP PREVENTING FROM THE PESTS ON TREES}

The present invention relates to a tree guard, and more particularly to a tree guard for environmentally friendly pest control having a two-layer structure.

Conventionally, in order to control pests, by using straw or rope to wrap the trees in the fall, a latent insect pest is made, and the pupa of the pest that has been wintered in the late winter is incinerated. The killer band method has been used to remove pests. However, in recent years, not only is it difficult to obtain straw, but the labor cost is increased due to the work of winding and detaching straw, and there are disadvantages such as damaging the aesthetics after installation. For these reasons, research on pest control drugs has been conducted since the 1970s, and instead of using straw, a method of spraying various insecticides was used. However, most of the pesticides are highly toxic and not only directly or indirectly damage the human body, but also the drug is distributed to the surrounding area and is a factor that destroys the natural environment.

On the other hand, Japanese Utility Model Publication No. Hei 3-91750 discloses a wood insecticide rod in which a wood insecticide rod and a synthetic resin film are formed. However, these insecticidal zones are composed of all or part of hemp fibers, so that the warmth and the density of tissues are inferior, and thus the function as a wintering place of pests is poor, and the pests do not prevent the escape of the pests that are latent in the trees. There is a problem that is easy to be distributed to

On the other hand, the present inventors have applied for a patent for protecting pests of pests of two-layer structure and three-layer structure in order to solve the above problems (Patent Application Publication No. 2000-13561), but it is necessary to further improve the adhesion. there was.

Therefore, the object of the present invention is to solve the above problems, while maintaining the insect repellent / insecticide effect for a long time, to minimize the environmental pollution, and easy to capture pests, while timely proper control through a quick analysis, It is to provide a tree guard with improved adhesion.

1 is a perspective view showing the outer appearance of the tree guard for pest control applied to trees.

2 is a cross-sectional view of a tree guard for pest control of a two-layer structure according to an embodiment of the present invention.

In order to achieve this object, according to the present invention, the inner layer in contact with the tree, consisting of a hydrophilic web; And a non-woven fabric, the tree guard for pest control comprising an externally facing base material layer.

Referring to the present invention in more detail as follows.

In the present invention, it is preferable to use a nonwoven fabric prepared using only environmentally friendly hydrophilic fibers such as cotton, viscose rayon and pulp as the base material of the tree guard. Such a nonwoven fabric has a bulky structure and excellent breathability, has thermal insulation, and has a photosensitivity effect. In addition, such a nonwoven fabric is excellent in strength as well as elongation, and thus has weather resistance while maintaining its shape sufficiently when installed in trees.

On the other hand, as the web constituting the inner layer of the present invention, it is preferable to use an environmentally friendly hydrophilic fiber that has a high air content and high heat retention, and a structure in which sufficient space is provided between the fibers so that pests can easily penetrate. Examples thereof include cotton, viscose rayon, pulp and the like. Most preferably, viscose rayon is used.

Pesticides can be added to the inner layer while maintaining its form. As the pesticide, insecticides commonly used such as Sumition MC and MEP emulsion may be used. As the method of adding the pesticide while maintaining the shape of the web, wetting method, spraying method and microencapsulation can be used.

The tree guards are manufactured in strips 15-20 cm wide and 160 cm long, but can be sized according to the size of the tree. The tree guards can be fixed to trees by installing locks such as staplers, straps and rings on the outside of the tree guards.

In addition, when the tree guard of the present invention is installed in the roadside tree, it is possible to form a fluorescent stripe by adding a fluorescent material to the outside of the tree guard to prevent traffic accidents. Fluorescent stripes can be formed by conventional silkscreen printing, or by adhering fluorescent and reflective tapes.

Example

Example 1

A strip-shaped tree guard with a width of 15 cm x 160 cm was prepared using a base material made of a needle punched nonwoven fabric with hydrophilic viscose rayon fibers and a web made of hydrophilic viscose rayon fibers.

Example 2

A strip-shaped tree guard with a width of 15 cm x 160 cm was prepared using a base material made of a needle punched nonwoven fabric with hydrophilic viscose rayon fibers and a web made of hydrophilic viscose rayon fibers. At this time, Sumichion MC (MEP emulsion) was added as a pesticide to a web made of viscose rayon fibers by the spray method.

Comparative Example 1

A strip-shaped three-layered tree guard, 15 cm wide by 160 cm long, was prepared having an outer layer made of Hessian cross, an intermediate layer made of jute, and an inner layer made of cotton nonwoven fabric.

Test Example 1

Guards of Example 1 and Comparative Example 1 were installed for pine trees. Each tree guard was installed at a height within which it could reach from the point of contact with the ground to 2m from the ground, and the guard was tightly wrapped so that outside insects could not enter and exit. Confirmed and compared the number and population of insects introduced into the tree guards of Example 1 and Comparative Example 1 for wintering in winter from September 2001 to November and from November 2001 to March 2002 It was. The results are shown in Table 1 below.

Installation period Guard type Number of guards Insect species Total insect population Average number of insects September to November 2001 Example 1 9 8 21 2.3 Comparative Example 1 5 4 9 1.8 November 2001 to March 2002 Example 1 6 6 9 1.5 Comparative Example 1 10 7 10 1.0

From Table 1, it can be seen that the tree protector according to the present invention, excellent function as a wintering place of pests, and prevents the escape of pests latent in the tree.

According to the present invention, by eliminating the disadvantages of the prior art, while maintaining the insect repellent / insecticidal effect for a long time, it is possible to minimize the environmental pollution, it is easy to capture pests, it is possible to timely control appropriately through rapid analysis, adhesion An improved superior tree guard is provided. In addition, forming a fluorescent stripe outside the tree guard of the present invention has the effect of preventing traffic accidents.
