Abstract

PURPOSE:To obtain the title band cloth with its end(s) made thicker so as to produce spaces when wrapped around a tree by coating or impregnating a band cloth made by weaving, knitting or nonweaving processing using coarse thread with an insecticide-contg. aqueous dispersion formulation giving insoluble or hard-to-dissolve nature to water when dried. CONSTITUTION:The objective band cloth can be obtained by coating or impregnating (A) a band cloth made by weaving, knitting or nonweaving processing using coarse thread (pref. jute) with its end(s) in the width direction made thicker with (B) an insecticide-contg. aqueous dispersion formulation giving insoluble or hard-to-dissolve nature to water when dried. To make the end(s) of the band cloth thicker, thread 2 to 5 times thicker than that making up the hand cloth is woven, stitched with a sewing machine or made to adhere; or a paste is applied in a thicker manner. Thereby, when the present band cloth is wrapped around a tree, spaces sufficient for insects to creep will be produced between the band cloth and the tree, leading to luring and killing insects. Application of e.g. machine oil on said cloth will prevent the insecticide from losing even if the cloth is exposed to rainfall.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a tree band that can be wrapped around the frame or branch of a tree to protect the tree from sun damage, cold damage, insect damage, etc.

Conventional technology Conventionally, a tape layer made of non-woven fiber 5 or felt 1 is coated with an adhesive layer containing an adhesive and an insecticide. This tape is tightly wrapped around the outer branches of the tree (there is a tape available (Utility Model Publication No. 41-3089)), but the interposition of the adhesive layer impairs air permeability, which hinders the growth of the tree. In addition, since the insecticide in the adhesive layer is not present on the surface of the tree that adheres to the tree, it may prevent flying insects from laying eggs on the cloth surface. , could not prevent the larvae from crawling across the surface of the tape.

In addition, as another example, a tree cover belt 'ffi made of coarsely woven fibers such as jute linen and impregnated with an insecticide such as D-r is weakened (Jetko Kouko 49-31).
655M > When wrapped around the tree trunk, this tree covering band does not have a gap between the tree trunk and the band, so it cannot attract and kill longhorn beetles and overwintering pests that prefer contact areas. However, there were drawbacks such as the possibility that it would flow into the water and pollute the natural environment.

Problems to be Solved by the Invention Addressing the above-mentioned problems of the prior art in tree protection banding,
The problem of the present invention is that it is breathable to trees, and since there is no outlet for rainwater from mulberry shavings, it has a large insecticidal effect against pests.
To provide a tree bandage which does not pollute the environment due to mulberry agents, and which has a suitable gap when wrapped around a single tree and can attract and kill pests that prefer warm places into the gap. There is a particular thing.

As a result of extensive research, the inventors of the present invention have developed a V (i) material made of coarse thread, which is designed to maintain a suitable gap for insects to crawl through when wrapped around a tree. In addition to devising a method, they succeeded in solving the above problem by using a band coat coated with or impregnated with an aqueous dispersion containing an insecticide that is insoluble or soluble in water when dry.

That is, the present invention provides (1) a belt t woven, knitted or non-woven with coarse yarn;
(A tree strip (11) characterized in that it is coated with an aqueous dispersion formulation containing an insecticide and having properties of being insoluble or poorly soluble in water when dried (1) and/or avoiding impregnation. (2) The tree banding cloth described in (1) above, in which thread is woven, sewn or glued at one or both ends in the obi direction (7) lI]; [I
This is the wood band 11 described in (1) above, in which a glue is applied thickly to one or both ends in the Jh direction.

Structure of the Invention [Material of Band I 1i] The band 4 (i) used in the present invention is breathable and compatible with the aqueous dispersion preparation described below when it is coated or impregnated with the preparation.

Such a band is made by processing coarse natural fiber yarn, preferably linen yarn such as jute, into a band-shaped 45 material. A5 The method of processing the shrine is not particularly limited, and any method such as weaving, knitting, or non-woven fabric processing may be used.

The number of Obi IT [1] can be set arbitrarily depending on the tree to which it is applied, but it should be suitable so that insects can crawl between Obi I 5 and the tree surface when wrapped around the tree. space (
It is advisable to make the thickness near one or both ends of the band in the width direction large enough to maintain a gap (gap).

19 can be made larger by using threads of the same thickness as the threads constituting the obi 11, or 2 to 5 threads thicker than that.
Methods include weaving, sewing, or gluing a double-thick thread onto one or both ends of the obi 4i, or applying a thick layer of glue (glue) to one or both ends of the obi 1i. .

As an example, FIG. 1 shows a plan view of a band 111 in which a thick thread is sewn in a zigzag pattern near both ends in the rlJ direction using a sewing machine.

[Insecticide-containing 1"q-aqueous dispersion preparation] In the present invention, the insecticide-containing preparation to be applied and/or impregnated onto the band A can be diluted with water when it is applied to the band A, and when heated and dried, it dissolves in water. It is insoluble or poorly soluble.

Insecticides that are active ingredients in aqueous dispersion preparations include 4″i
Permethrin-based insecticides, carbamate-based insecticides, pyrethroid-based insecticides, neraistoxin-based insecticides, and the like may be selected as appropriate, but it is particularly preferable to use pyrethroid-based insecticides such as permethrin. This type of insecticide has excellent insecticidal power, fast-acting properties, and a residual effect of 1 liter, has repellent effects such as preventing egg-laying, has extremely low toxicity to humans and livestock, and has almost no chemical damage to trees. It is something.

When treating band 5 with an insecticide-containing preparation, it is diluted with water, and after drying, in order to mark the insecticide as insoluble/e [or poorly soluble in water, it is necessary to use a preparation that has an affinity for the insecticide together with the insecticide. Alternatively, it is necessary to prepare an aqueous dispersion preparation by using a soluble, water-insoluble and non-volatile Δyl component and dispersing it in water with a dispersant. By using such a formulation, it can be diluted with water during treatment, and after drying, the insecticide is dissolved or mixed in a water-insoluble, non-volatile oil component, leaving the area coated or impregnated with the insecticide. Therefore, even if exposed to rain, the insecticide will not wash out and will continue to be effective for a long period of time.

For the purpose of making the material insoluble or poorly soluble in water, an insolubilizing agent such as glutaraldehyde or epichlorohydrin may be added if desired.

Machine oil and synthetic oil can be used as the water-insoluble and non-volatile Δ-il component, but machine oil is preferred. This is because the machine oil itself has an insect repellent effect, making it difficult for insects to approach to lay eggs, and even the rare insects that do approach are killed by using the insecticide. I can hear 1q.

As the dispersant, those commonly used in the field of aqueous dispersion preparations, such as polyvinyl alcohol and latex, can be used.

In addition, the insecticide-containing aqueous dispersion formulation according to the present invention may include thickeners such as gum tragacanth, giraffe tankum,
Sodium alkinate, methyl relrose, 11 sales Ageli Seal Fl-100F (product name: Hanadama Co., Ltd. M>
, DK Ramzan (trade name: manufactured by Dai-Kogyo Seiyaku Co., Ltd.), etc. can be used. The amount of these thickeners added is 0.1
It is in the range of ~20% by weight, but the optimal addition (2) differs depending on each thickener.

Furthermore, the insecticide-containing water/[1 dispersion formulation according to the present invention]
Antifungal agents, fungicides, etc. can also be used in combination as other ingredients.

[Target Pests 1 The target pests of the band of the present invention are longhorn beetles (e.g., Japanese longhorn beetle, red-eared beetle, etc.) and overwintering pests (e.g., Japanese pine beetle, Japanese bush moth, Japanese larch wood moth, etc.) that prefer warm, dark places. It is.

[Treatment of Band Fabric] The method for applying or impregnating the aqueous dispersion preparation on the fabric may be a conventional method, such as a roller method, a spray method, a dipping method, or the like.

The amount of coating/li@ depends on the insecticide used, but in general, the amount of insecticide used varies from 10 to 10 grams per square meter.
It is.
