Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for killing vine plants such as vines and wisteria. More specifically,
The present invention relates to a method for selectively killing vine plants with good workability and efficiency by injecting an active ingredient chemical solution directly into a plant body.

[0002]

2. Description of the Related Art Kuzu is a perennial climbing plant that grows vigorously in summer, has large roots, and regenerates even when its foliage dies. In forest land, the trunks are deformed and curved by clinging to the seedlings and mature trees, and the leaves shade the forest trees, hindering their growth and causing serious damage to forestry. In addition, it may be wound around telephone poles, causing danger of electric leakage, or climbing up on fences and damaging the landscape. A similar problem exists for wisteria, a vine plant.

[0003] Techniques currently practiced for the purpose of eliminating harm from kudzu include: 1. A method of cutting the stalks of kudzu with a sharp knife. 2. a method of spraying a contact transfer type herbicide on the shoots and leaves of kudzu; A method in which a hormonal herbicide is dropped on a kudzu plant head, 4.4 A toothpick-shaped wooden needle adsorbing potassium 4-amino-3,5,6-trichloro-2-pyridinecarboxylate is stuck in the kudzu plant head. Method, 5. A method in which an amino acid-based herbicide is applied to a portion of a kudzu stalk that has been damaged with a knife using a dropper or the like (Japanese Patent Laid-Open No. 4-29)
0807).

[0004] A kudzu is a tuberous root like a root, and if the root is alive even if the foliage is withered, it is regenerated vigorously. Therefore, the method of cutting a stem with the above-mentioned sharp cutting tool is transient and regenerates. Therefore, a method of digging and removing the root by human power is also conceivable,
It takes a lot of effort and time and is not practical. The method of spraying the above two chemicals on foliage has a problem in selectivity, and there is a high risk of causing phytotoxicity to nearby crops. In addition, full spraying in a forest area may lead to pollution of a watershed forest, resulting in environmental problems. This is not the preferred method.

[0005] The above 3 is an MDBA dimethylamine (2-
Methoxy-3,6-dichlorobenzoic acid dimethylamine)
Hormone agents are used, but hormones act during the growth of the plant to cause abnormal growth and kill the plant, so the treatment time is limited to the growing season of kudzu (spring and summer). However, there is a problem that it is not easy to find the head of the kudzu that coexists with other weeds in the thickened area of kudzu, and the workability is extremely poor.

According to the method of inserting a wooden needle into the head of a kudzu (4), the kudzu can be selectively removed, but as in the case of (3), the kudzu is coexistent with other weeds in a thickened area of kudzu. It is not easy to find the kudzu stock and the workability is extremely poor.

[0007] In the method of 5 mentioned above, the stem of a kudzu is scratched with a knife and a chemical solution is put thereon using a dropper or the like, so that the chemical solution is easily spilled. It is nervous, takes a long time to process, and is inefficient. Therefore, the chemicals for removing vines such as kudzu can be labor-saving and work-processed regardless of the season, and an appropriate amount can be administered to the plants without spilling chemicals, effectively killing the vines. There is a strong demand for a processing method for causing this.

[0008]

Means for Solving the Problems The present inventors have developed a non-selective, transferable amino acid-based herbicide to meet such a problem.
According to the process of inserting a container into a small container having an injection tip port and inserting the tip of the container into a hole drilled in a stalk of kudzu, which is slightly away from the head of the plant, and injecting the chemical solution into the plant body, the foliage portion, as well as the root portion It was confirmed that an extremely excellent effect was obtained in which the work treatment was performed not only during the growing season of kudzu, but also during the autumn or winter season, and no regeneration of kudzu was observed. This treatment method can also be expected to have an effect on vines, which are vines.

That is, the present invention is to 1) making a hole in the stem of a vine plant, inserting the tip of a small container containing a herbicide solution into the hole, and injecting the solution into the vine plant. 2) Herbicide is trimethylsulfonium-N- (phosphonomethyl) glycinate (glyphosate trimesium salt), N- (phosphonomethyl) glycine / isopropylamine salt (glyphosate) Ammonium-DL-homoalanin-4-yl (methyl) phosphinate (glyphosinate) and L-2-amino-4-[(hydroxy)
(Methyl) phosphinoyl] butyryl-L-alanyl-
The method for killing vine plants according to the above 1, which is selected from L-alanine sodium salt (bialaphos); 3) The method according to the above 1 or 2, wherein the vine plants are mulberry; and 4) Outside the tip 4. The method according to any one of 1 to 3, wherein a small container is used which is stably held at least for a time required for injecting a drug solution while being inserted into the hole having a diameter larger than that of the stem. Hereinafter, the method of the present invention will be described in detail for kuzu, but it will be apparent to those skilled in the art that the method can be applied to wisteria instead of kuzu.

[Small Container] The present invention is characterized in that a herbicide effective for mosquito is put in a portable small container, and an appropriate amount of a medicinal solution is directly injected into stalks (stems) of kudzu to control. It is preferable that the container has a capacity of 1 to 5 ml and has a shape with a thread or a projection at a tip portion so that the container does not easily come off when inserted into a hole formed in a kudzu stalk. The diameter of the injection hole of the container may be 3 to 7 mm, but 4 to 5 mm is more appropriate in consideration of the thickness of the target kudzu stalk and the workability.

The material of the container may be any material as long as it is resistant to the contained chemical solution, but is preferably made of a resin such as polyethylene, polypropylene, vinyl chloride, nylon, etc., which is easy to manufacture. Examples of the shape of the container are shown in FIGS. FIG. 1 is a cylindrical container with a threaded tip injection section, and FIG. 2 is a tube-shaped vessel also having a threaded tip injection section, but having a linearly adhered bottom. FIG. 3 shows an ampoule-type container of a type in which a cut portion (not shown) of an uneven tip portion is cut at the time of use, and the cut tip portion of the container is inserted into a hole.
In addition, the above-mentioned container is only an illustration and is not limited to these, and any container may be used as long as it has a similar function.

[Stem Drilling] A hole is drilled in a kudzu stalk with a drilling knife. Punches and drills that use a spring mechanism to make holes can be used as drilling tools, but the holes made with the punch are not correct circles, and because they are slightly spindle-shaped, especially stalks of kudzu A vertical drill is preferable because a chemical solution easily leaks when it is vertical. As the drill, a woodworking drill or an ironworking drill (3 to 7 mm, preferably 4 to 5 mm) corresponding to the diameter of the hole to be drilled can be used. Woodworking drills are also commercially available that have a sharp tip (projection) for positioning the hole. By inserting the tip slightly into the part where you want to drill the hole and turning it, you can accurately drill the hole at the target site. Can be opened.

[0013] In addition, these drills are projections which are used as substitutes for perforation for making air holes in the small container when the small container is attached to the kudzu stalk after the small container is inserted into the hole so that the medicinal solution is quickly injected into the kudzu. Are preferred. The depth of the hole in the stem is
It is preferable that the injection hole portion of the small container can be inserted completely, and that a protrusion such as a screw thread can be inserted to the inside of the hole.
The diameter of the hole in the kudzu stalk and the diameter of the injection hole of the small container are not the same, and when the tip of the small container is inserted into the kudzu stalk, it is held firmly so that the drug solution does not leak out and the drug It is preferable to make the injection hole portion of the small container 0.5 to 0.8 mm larger than the hole so that the injection can be stably maintained during the complete injection (usually for about 15 to 20 minutes). At this time, the screw threads and the like help the stable holding of the small container so that it does not come off from the stem of the kuzu.

[Drugs] The herbicide to be used in the present invention may be any herbicide effective against kudzu. Since it is directly injected into the plant of the kudzu, it is possible to use a drug having a low herbicidal effect and a high herbicidal effect. Preferred are herbicides which can penetrate into plants, and amino acid-based herbicides which are liable to decompose and disappear in soil after dying of mulberry are environmentally preferable. Examples of such amino acid herbicides include trimethylsulfonium-N- (phosphonomethyl) glycinate (glyphosate trimesium salt), N- (phosphonomethyl) glycine / isopropylamine salt (glyphosate), and ammonium-DL-homoalanine- 4-yl (methyl) phosphinate (glyphosinate) and L-2-amino-4
-[(Hydroxy) (methyl) phosphinoyl] butyryl-L-alanyl-L-alanine sodium salt (bialaphos).

[Regarding the dosage] The concentration of the herbicide formulation used in the formulation is not preferable if the viscosity is too high because the liquid is difficult to come out of a small container. Therefore, it is preferable that the concentration is as high as possible and as small as possible. In addition, the amount of drug to be injected per kuzu depends on the component concentration of each drug, the treatment site (distance from the stock head), the thickness of the kudzu stalk, and the size of the stock head. Changing the amount of the treatment agent depending on the size of the squid makes the operation cumbersome, so it is preferable to unify the treatment agent amount to a universal one. In the test according to the present invention, when 2 ml of the chemical solution was injected to a relatively large stem having a stem diameter of about 2 cm, the kudzu of the thickness before and after that was almost completely killed. However, some kudzu with a stem thickness of 4 cm or more could not be completely killed, but in this case, 2 ml and two injections can cope.

[Treatment time] The treatment according to the method of the present invention does not need to be carried out at any time, and it is not always necessary to carry out the treatment from March to October, which is the growing season of kuzu. That is, a sufficiently high effect can be obtained by the treatment with the above-mentioned chemical solution even in the winter period when the surrounding weeds are withered and the kudu growth is halted, which allows easy work.

Test Example 3 Test Using Small Container (Winter Treatment) Commercially available drugs such as glyphosate trimesium salt (38%), glyphosate (41%), glyphosinate (18.5%) and bialaphos (32%) were injected into the tip. 1 ml or 2 ml was filled into a portable polyethylene container having a hole (the injection hole was 5.08 mm). In the forest, in the winter season (mid-January) when the growth of kudzu is halted, kudzu with a diameter of about 2 cm at the treatment site (1 to 2 m away from the head of the plant) was selected and treated with drugs. In the small bottle method using a small container, a hole with a diameter of 5 mm and a depth of 7 to 10 mm is made with a woodworking drill, and the small container is screwed. The air hole was opened with. In the peeling method, a fence-shaped flaw was attached to a kudzu stalk so that the medicinal solution could be easily placed using a small knife, and the medicinal solution was dropped onto the bark. In the vine cutting method, the stem near the kudzu plant head was cut with a sharp knife such as nata. In each treatment method, three strains of kudzu were tested, and after 6 months, the presence or absence of regeneration was examined based on the following criteria.
Table 5 shows the results.

Judgment criteria: 1 ... no reproduction, 2 ... reproduction small, 3 ... medium reproduction, 4 ... reproduction large.

[0027]

Test Example 4 Relationship between thickness of kudzu stalk and dose (winter treatment) A portable polyethylene container having an injection hole at the tip of a commercially available glyphosate trimesium salt (38%) (5.08 mm injection hole) ) Was filled with 1 ml, 2 ml, and 3 ml.
In the woodland, in the winter season (mid-February) when the growth of kudzu is suspended, the diameter of the stem 1.5 m away from the plant head is about 1 cm and 2 cm.
A kuzu of about 3 cm or 4 cm was selected, a hole having a diameter of 5 mm and a depth of 7 to 10 mm was opened in the stem with a woodworking drill, a small container containing a drug was screwed into the hole, and the drug was injected. 4
In the ml section, two holes were made in the stem, and two 2 ml pieces were inserted and the drug was injected. Also, in order to speed up the injection of the drug, an air hole was perforated at the bottom of the portion opposite to the injection hole. In addition,
In each ward, three strains of kudzu were tested, and the presence or absence of regeneration was investigated 6 months after treatment based on the following criteria. Table 6 shows the results.

Judgment criteria: 1 ... no reproduction, 2 ... small reproduction, 3 ... medium reproduction, 4 ... large reproduction.

[0030]

From the results shown in the table, a small container containing a medicine is screwed into a hole drilled in a kudzu stalk, and an appropriate amount of the medicine is directly injected into the stalk of kudzu. However, it can be seen that kudzu can completely die.

[0032]

According to the method of the present invention, a small container containing a drug is screwed into a hole drilled in the stem of a vine plant, thereby sufficiently killing the vine plant without spilling a chemical solution. A large amount of leaves can be injected into the stem of a kudzu. For this reason, since a certain effect can be obtained by processing the portion (1 to 2 m) slightly away from the stock head, it can be processed at a portion where the work is easy, and the working efficiency is remarkably improved. In addition, since the regeneration can be suppressed even when treated in winter when the growth of the vine plants is suspended, it greatly contributes to the employment problem of forest workers in winter, when there is relatively little work in forestry.
