Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the diseases and pests of trees.
The present invention relates to the one that moves from the soil through the surface of the bark to the upper part to damage the trees, and the one that prevents the pests from moving to the upper part through the surface of the wood material behind the bark to damage the trees.

[0002]

2. Description of the Related Art Conventionally, pest control for preventing pests from trees is
Mainly spraying control chemicals on trees, there is a method of spraying using a manual sprayer, a method of using a power sprayer, or a method of spraying from the air by flying a helicopter or a light aircraft on a large scale.

[0003]

The spraying method in the prior art effectively acts on trees by the sprayed control chemicals, but excess chemicals cause small animals or insects that live in other plants or trees or forests. It spreads to species and microorganisms, and in some cases, it has caused adverse effects by inflowing into rivers and lakes, inflowing into the ocean and pollution.

The present invention has been made in order to reduce the frequency and labor of spraying these control chemicals, to suppress the damage to the other by the excessive control chemicals to the utmost, and to prevent pollution.

[0005]

[Means for Solving the Problem] A pest-damage prevention band is intended to prevent pest-damage, and the pest-damage prevention band is a long film of water-soluble or biodegradable plastics, perforated film, woven fabric, or For spider web sheets and non-woven sheets, powders, granules, pastes,
It is a drug band in which a controlling agent for pests and diseases, such as a tablet or a drug obtained by encapsulating these drugs with a water-soluble material, is continuously contained. The purpose is achieved by arranging the drug band around a key part of a tree, most of which is a root trunk.

The above-mentioned drug band is prepared by placing a control agent on a film or the like and further bending the film in the width direction so as to cover the control agent or the like, or after placing the control agent, further. Films of the same width are overlapped, the ears are welded, and partitions for preventing uneven distribution of the control chemicals in the lengthwise direction are applied by a method such as welding to complete a long chemical band.

The drug band is cut to the circumference of the tree so as to have a length corresponding to the overlap margin, and is wound around a key point of the tree and tied with a string or staples are placed. Stick to it.

[0008] In the case of a film, it is gradually decomposed by rain, dew, irrigation, etc., and the contained control agent also begins to flow, and the surface of the tree and the deep part of the bark layer below the circumscribed portion of the pest prevention band of the tree. , Reaches the surface of wood and exerts a protective function. In addition, if the material is a material such as perforated film, woven fabric, cobweb-shaped sheet or non-woven sheet that allows water, such as rain, dew, and irrigation, to enter easily, the contained control agent will immediately flow out. Will exert a protective function. At this time, when a protective effect is expected in the long term, it is more effective to mix the encapsulated drug.

[0009]

[Function] The chemical band circulated on the tree flows out of the control chemicals due to rain, dew, irrigation, etc. and reaches the surface of the bark below the circumscribed part and the deep / woody surface of the bark layer, giving a substantially constant concentration It protects pathogens and pests from the ground and the surface to the top of the tree by exerting a protective effect over a long period of time. The effect is significantly reduced and the efficacy is prolonged.

In the case of a water-soluble film, for example, polyvinyl alcohol, the drug band is dissolved by water and eventually penetrates into the ground. , That has almost no effect.

[0011]

[Example] The drug band (2) as a band-shaped material is made of
Polystyrene, polypropylene, polyvinyl alcohol and various biodegradable plastics can be used, and the state is a film, a perforated film, a woven cloth, a cobweb sheet, or a non-woven cloth, and has a long required width. Two long chemical bands (2) are stacked or folded from the center to form two layers, and the control chemical (3) is enclosed between the two layers. The control chemical (3) is the same as the chemical band (2). Depending on the state, it is made into powder, granules, paste or tablet.
A controlling agent (3) in which these controlling agents (3) are further encapsulated with a water-soluble material can be selected. And
These control agents (3) are applied to the agent band (2),
Enclose continuously such as at fixed intervals or fixed intervals.

The chemical band (2) in which the controlling chemical (3) is enclosed is cut to a required length, and the tree root trunk (4) is directly cut.
It can also be installed around the tree, but in order to reinforce the drug band (2) and to stably supply the drug components with water, the cover band (5) is further used to fix the drug band (2) to the tree. It may be installed around the trunk (4). Similar to the drug band (2), the cover band (5) made of a band-shaped material can use polyethylene, polypropylene, polyvinyl alcohol, various biodegradable plastics and polyvinyl chloride as its material, and the state thereof is a film, Perforated film, woven fabric, cobweb sheet, non-woven fabric,
In the case of a film, the cutouts (6) are partially
It can also be used as a cover band (5).

The drug band (2) is affixed to the surface of the cover band (5) to form a two-layer and long pest damage prevention band (1). For that purpose, a two-layer preparation can be facilitated by installing a narrow adhesive tape on the back surface of the cover band (5), or by applying a wood-like print on the surface, when the tree root trunk (4) is installed. You can also eliminate the appearance discomfort. Furthermore, by making a notch (7) in one or both of the cover bands (5), the notch (7) part floats up from the tree root trunk (4) at the time of rotation, and insects that move on the bark are covered. It can also be prevented from passing over the band (5).

In the present embodiment, a 0.2 mm thick film of polyvinyl alcohol was used as the drug band (2) to have a width of 100 mm, and the pine wood nematode control agent was quantitatively and continuously placed on the film. Was diffracted for 2 minutes in the width direction to seal the ears, and dot-shaped sealing points were provided in the longitudinal direction. Further, as a cover band (5), a biodegradable plastic film having a thickness of 1 mm and a width of 100 mm is partially cut to form a water inlet (6), and a cut (7) is further formed on one side to
The adhesive band of 0 mm width was used to overlap with the drug band (2) to form two layers, which were wound around the tree root trunk (4) of the pine tree and tightened with the polypropylene string (8).

[0015]

EFFECT OF THE INVENTION By means of a drug band and a cover band, 2
The pine tree with a layer of pest control band circulated does not die at present and is in good vigor without spraying control chemicals. This band system reduces the labor, labor hours, drug amount, contamination, and other effects of drug spraying. Especially, the drug spraying system was changed to a band-wiring system to reduce labor and drug consumption. Made it possible to save a lot of. In addition, the effect lasts for a long time and exerts a remarkable effect in preventing pests. In addition, there is no pollution of the environment due to spraying, and it can be expected that the impact on the ecosystem of trees and forests at the time of large-scale spraying will be drastically reduced, which in turn contributes to the conservation of the earth's environment.
