Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying harmful insects and harmful bacteria such as pine wood nematodes (hereinafter referred to as nematodes) by supplying chemicals, water and liquid fertilizers to trees such as trees and fruit trees. The present invention relates to a method of supplying a chemical solution or the like to trees for performing curing, controlling growth, and improving quality in transplanting trees in addition to control.

[0002]

2. Description of the Related Art In order to control pests, harmful bacteria and the like of trees, a method of spraying a chemical on the whole tree using a sprayer is generally employed. There is also a method of spraying or injecting a drug into soil to absorb the drug from the root. Recently, a method has been adopted in which a hole is formed in the stem and a chemical solution or the like is directly injected into the inside of the stem (stem injection method or stem treatment method).

[0003]

However, spraying with a sprayer has little efficacy against harmful insects such as nematodes that infiltrate the inside of a tree. In addition, it is affected by the weather when spraying, and it takes time to spray. In addition, the effects on humans and the environment by spraying cannot be ignored. In the case of spraying on soil, there is also a problem of environmental pollution.

On the other hand, a method of forming a hole in a trunk may not only deteriorate the aesthetic appearance due to a hole remaining in the trunk, but also cause rot, growth abnormality, decrease in strength, and the like due to scars on the trunk. In addition, when the conventional trunk injection method is applied during the period of active resin flow (April to October period), absorption of the injected chemicals and the like by the flowing resin is significantly inhibited, so the construction period is November. Limited to March.

Therefore, the present invention is simple in operation, less burdens on trees, and can be constructed in a cold season without causing environmental pollution, and is particularly effective in controlling nematodes. It is an object of the present invention to provide a method for supplying a chemical solution or the like to a tree exhibiting the above.

[0006]

In order to achieve the above object, according to the present invention, a small hole is formed by piercing the outer surface of a branch without cutting the branch, and a chemical solution or the like is stored in the small hole. By inserting an ampoule, the chemical solution or the like is supplied to the inside of the branch.

Further, a small hole penetrating from the outer surface of the branch to penetrate to the pulp of the branch is formed, and the injection tube portion of the ampoule containing a chemical solution or the like in the small hole is used for leaking the chemical solution or the like and fixing the ampoule. By inserting it through a short rubber tube having the function of (1), the injection tube and the medulla are communicated with each other, and the drug solution or the like is supplied to the inside of the branch.

In addition, the ampule is installed on the branch with a predetermined inclination from the vertical direction to the branch direction, and the predetermined inclination is 0 ° to
The angle may be set to 60 °, or the ampule placed on the branch may be removed within 8 hours after the completion of the supply of the chemical solution or the like.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments.

FIGS. 1 and 2 show an embodiment of a method for supplying a chemical solution or the like to a tree according to the present invention. First, a diameter of 3 to 3 penetrated to the pulp P by drilling from the outer surface of the working branch B of the target tree T with a drill or the like.
A small hole 1 of about 15 mm is formed.

Next, the small hole 1 has an outer diameter of 3 to 15 mm,
A slightly thick rubber tube 4 with a length of about 10 mm is inserted. The injection tube portion 2a of the ampule 2 containing the chemical solution F or the like is inserted into the rubber tube 4 from above, and the ampule 2 is installed with a predetermined inclination θ from the vertical direction to the branch direction. In this way, the injection tube portion 2a and the medulla P are communicated with each other, and the drug solution F and the like are supplied to the inside of the branch B.

As described above, when the predetermined inclination θ is set at 30 ° ≦ θ ≦ 60 °, the injection cylinder 2a can be inserted into the branch B longer than when the ampoule 2 is installed in the vertical direction. It is. Thereby, the ampoule 2 is securely held on the branch B without falling down. At the start of the supply of the chemical F or the like, as shown in FIGS. 1 and 2, on the bottom surface of the ampoule 2 or on the side wall surface close to the bottom surface, small air holes (pits) 3 having a diameter of 1 mm from outside to inside are formed. Let it penetrate.

Then, as shown in FIGS. 2 and 3 (a), after the chemical F or the like is supplied from the injection cylinder 2a to the inside of the branch B by natural pressure, the chemical liquid F is once directed toward the branch tip. , In the direction of arrow A. After reaching the branch tip, it is sent in the direction of arrow C toward the trunk D.

Thereafter, as shown in FIG.
Of the tree T, when it reaches the root R, it is again sent upward toward the top end of the tree T. The chemical solution F or the like that has reached the top end then changes its flow toward the base of the stock, and is sequentially delivered from the upper branch B to the lower branch B. As a result, the chemical solution F and the like spread throughout the tree T. In addition, it takes about 60 days for the chemical solution F to penetrate the entire tree.

The target tree T of the present invention is a tree such as pine, ginkgo and cherry, and a fruit tree such as pear and apple.
Further, as the ampoule 2 used in the present invention, a commercially available ampule can be widely used, and no special device is required. The chemical F etc. stored in the ampule 2 is
Shows liquid insecticides, acaricides, fungicides, nutrients, fertilizers, growth regulators, etc.

In particular, the present invention is an optimal method for supplying a commercially available drug for controlling a nematode, which is a pathogen of acute wilt of pine, to a tree. In this case, examples of usable chemicals F include Nemanone (Nippon Bayer Co., Ltd.), Green Guard (Pfizer Pharmaceutical Co., Ltd.), Megatop (Nippon Cyanamid Co., Ltd.) and the like. Among the commercially available products for other uses, pot-in of a plant nutrient (Fumakiller Co., Ltd.), a plant revitalizing agent (Rainbow Pharmaceutical Co., Ltd.) and the like are available.

Since the whole amount of the chemical F etc. is supplied into the branch B within 8 hours, the ampule 2 attached to the branch B can be quickly removed from the branch B in about 8 hours. . However, it is often the case that almost the entire supply is completed within about 2-3 hours. In such a case, it is preferable to remove in about 3 hours in order to reduce the burden on the plant.

Next, according to the method of the present invention, 40 ml of Megatop manufactured by Nippon Cyanamid Co., Ltd. was added to the branches of six Japanese black pine (Experimental Examples 1 to 6) selected from a pine forest at the Arid Land Research Center of Tottori University. Table 1 shows the results of the experiment in which the injection was performed in about 2 hours. This megatop is an ampoule-shaped solution containing nemadectin as the main active ingredient, and is effective in preventing nematodes, the causal agent of acute wilt of pine. The effect is said to last for two years after injection.

[0019]

[Table 1]

As shown in Table 1, the breast height diameter is 5 cm to 11
cm, the tree height is 3.8 to 5.5 m, and the test tree is 15 to 20 years old (the tree height is lower than the tree age because it is planted in sand dunes). No infestation occurred even when the insects were inoculated.

The present invention can be freely changed in design in addition to the above-described embodiment. For example, as shown in FIG. 3, a plurality of ampules 2 may be provided for one target tree T.

[0022]

The present invention has the following remarkable effects by the above-mentioned structure.

According to the first aspect, since the ampule 2 can be attached by a simple operation without cutting the branch B, the efficiency of the operation is high and the burden on the target tree T can be reduced. . In addition, since the chemical solution F can be spread over the entire tree T regardless of which branch B is attached, work at high places can be omitted in many cases, and safe work can be performed. If desired, a commercially available ampule 2 can be used, which is highly versatile, simple, and economical.

Further, in the branch injection method of the present invention,
Even during construction in the period from April to October, poor absorption of F etc. due to the flowable resin rarely occurs, and from November to March
The construction in the month, that is, in the cold season, can be avoided.

(According to the second aspect, in addition to the effect of the first aspect, the ampoule 2 is inserted through the short small rubber tube 4 into the small hole 1 penetrating to the central medulla P. Etc. F
It is possible to ensure that the chemical solution F or the like flows over the entirety of the tree T quickly without causing leakage. Further, the rubber tube 4 can prevent the leakage of the drug solution or the like F from the small hole 1 and can fix the injection cylinder 2a of the ampule 2 to the small hole 1.

(According to claim 3) Since the injection cylinder 2a of the ampoule 2 can be inserted long into the branch B via the short rubber tube 4, the ampoule 2 does not fall down. It can be reliably held on the branch B.

Since the ampoule 2 can be removed in a very short time (according to claim 4), the burden on the tree T is reduced and the work efficiency is very good. Also,
In addition to easy management of injection, the visibility is good, so there is little worry about forgetting to remove, and children can use ampules 2
And the danger caused by the chemical solution F or the like in the ampoule 2 can be prevented.
