Composition for Controlling Parasitic Hazardous Plants {Composition for Controlling Pest Parasitic on Tree}

The present invention relates to a tree parasitic harmful substance comprising S-sec-butyl O-ethyl 2-oxo-1,3-thiazolidin-3-ylphosphonothioate (common name: phosphthiazate) as an active ingredient. It relates to a biological control composition, a method for controlling harmful organisms using the composition and a method for protecting trees.

Japanese Patent Laid-Open Publication No. 60-136590 discloses that organophosphorus compounds containing phosphthiazate are useful as active ingredients of insecticides, mites and nematicides.

On the other hand, Japanese Patent Laid-Open No. 2-88590 discloses the usefulness of phostiazate as a negative optical isomer and its harmful animal control agent. There are Matsunozai nematodes as examples of plant parasitic nematodes. However, no specific description is found about its control.

When harmful organisms parasitic on a tree, the growth of the tree may be inhibited or the tree may wither due to effects such as cooling and toxins produced. In response to this problem, measures have been taken to inject drugs into tree trunks or incinerate some or all of the parasitic trees to prevent further damage, but there are still no effective measures found. .

It is an object of the present invention to provide a means for efficiently controlling harmful organisms parasitic in trees.

MEANS TO SOLVE THE PROBLEM As a result of earnestly examining for the said subject, the present inventors discovered that the desired objective can be achieved by using a specific active ingredient, and finally completed this invention.

That is, the present invention relates to a tree parasitic noxious control composition (hereinafter simply referred to as a composition) containing phosphthiazate as an active ingredient, and a method for controlling tree parasitic noxious organisms using phosphthiazate as an active ingredient ( Hereinafter simply referred to as control method) and a method of protecting trees (hereinafter simply referred to as protection method) using phosphthiazate as an active ingredient.

Best Mode for Carrying Out the Invention

Although optical isomers exist in phosphthiazate, the present invention includes the use of each isomer and mixture of isomers.

There are no particular limitations on trees to be protected, for example, trees such as pine, cedar and cypress; Fruit trees such as citrus fruits, apples, pears, figs, persimmons, peaches, grapes, chestnuts, cherries, plums, plums, loquats, nursing trees, plums; Yeongsanbaek, Cheukju, Sanda, Camellia, Mugunghwa, Cherry Blossom, Mokseo, Maple, etc. Among them, it is particularly effective for the control of harmful organisms parasitic in forest trees, and especially for the control of harmful organisms parasitic in pine trees. In addition, the pines to be protected include forests as well as parks, gardens, pine forests, and golf courses.

Examples of harmful organisms to be controlled include nematodes which adversely affect the growth of trees such as Matsunozai nematodes; Perforated pests that penetrate and plant in trees such as antlers such as Matsuno Madara antlers, tree insects such as pine insects, and weevils such as Matsunoshirashi weevils; Absorptive pests such as cockroaches such as Ezomatsugasa cockroaches, shellworms and rowworms; Leaf mites, such as cedar leaf mites; Flies, such as Matsuban tama paris and Sugitama paris; Hamaki moths, insects, minnow moths, caterpillars, and insecticidal insects such as leaf bees. Among them, it is effective for controlling nematodes and perforated pests, and is particularly effective for controlling Matsunozai nematodes and Matsunomadara sky cattle.

Since the composition of the present invention can control both nematodes and perforated pests, the trees can be efficiently protected from the damage of harmful organisms. For example, in the problem of pine wilting in pine trees, Matsunozai nematodes parasitic on pine trees and causing pine physiological abnormalities are the main factors. However, Matsunozai nematodes coexist with Matsunomadara sky cows, and the wide range of parasitic ranges by the Matsunomadara sky cows mediating Matsunozai nematodes does not lead to a fundamental solution only by the control of Matsunozai nematodes, the main factor of pine wilting. . Therefore, it is possible to exclude the main factor of inhibiting the growth of trees such as pine wilting (for example, to control Matsunozai nematodes), and also to eliminate secondary factors (for example, to control the Matsuno Madara sky cow, the medium insect). The composition of the present invention is very useful and practical because of its effectiveness over a wide range with low throughput.

The processing method of the composition of this invention is not specifically limited, For example, a water body injection | pouring process, a subsea soil treatment, a foliage treatment, a coating process, etc. are mentioned. As said water-body injection process, the method of processing to a stem or a root system of a tree, etc. are mentioned, for example. As soil treatment under water pipes, for example, a method of treating the soil with a dispersion liquid or a liquid preparation appropriately diluted with various diluents such as water, a method of digging the surface of the soil or soil by several cm, etc. Can be mentioned. In the above-mentioned treatment method, soil treatment under water is preferable, and among them, water-based soil irrigation treatment in which the dispersion liquid or liquid formulation itself diluted with various diluents, such as water, is irrigated to the soil is more preferable. In the treatment, it may be processed by a scattering device or manually. Soil irrigation under water can be a treatment method with several advantages, but there are no examples of commercial success in the field. The advantages include, for example, 1) a simple treatment method that does not require special functions, but only irrigates the chemical solution around the tree, 2) the treatment time is not limited, and 3) one tree. The time required for processing is shorter than the tree trunk injection process, which is often carried out commercially in the field, 4) the need for bottle recovery after the tree trunk injection process is unnecessary, and 5) the tree trunk injection process. Since it is not necessary to drill holes into trees, which are essential to the trees, they do not damage the appearance or cause decay of trees or deterioration of resistance due to entry of bacteria or snowstorms from drug injection holes.

The composition of the present invention can exert a desired effect by local treatment because the active ingredient phostiazeide penetrates and penetrates the trees, but the above-mentioned soil treatment with water, more preferably soil irrigation, as mentioned above The treatment is particularly useful because phosphthiazate, the active ingredient, penetrates from the roots to the tree trunks and exerts a desired effect. For example, harmful organisms living in pine trees, more specifically inside tree trunks, branches, and / or roots, such as Matsunozai nematodes, Matsunomadara sky cows, etc. It can control by local treatment of the composition of this invention.

In addition, the composition of the present invention can exhibit both a prophylactic and therapeutic effect. In other words, the treatment is carried out at any time before tree damage occurs or before the presence of parasitic noxious organisms to obtain the desired effect, and after the damage of the tree or after the presence of parasitic noxious organisms is confirmed. You can take both steps to get the desired effect.

The treatment of the composition of the present invention is regulated collectively depending on the type and size of trees to be protected, the type and occurrence of harmful organisms to be controlled, the weather, soil conditions, treatment time, and the type of preparation. Can not. In the present invention, the concentration of phostiazate, which is an active ingredient, in the trees is usually 0.1 to 100 ppm, preferably 1 to 10 ppm. The throughput is, for example, in the case of a tree having a chest diameter (diameter of the stem about 1 m from the ground) of about 10 cm, the phosphthiazate per tree is in the range of 5 to 400 g, preferably 20 to 100 g. . However, the optimum treatment concentration or throughput can be individually determined by appropriately performing a preliminary test in consideration of the various conditions described above.

The control method of the present invention is a method of controlling harmful organisms by treating phosphiazete as an active ingredient to trees or surroundings to be protected so as to have the aforementioned treatment concentration or throughput. As the processing method, various methods can be adopted as described above, and the processing time can also be selected at any time. The protection method of the present invention is a method of controlling harmful trees by protecting harmful trees in this way.

In the present invention, other tree parasitic harmful control components can be used in combination or in combination with phosphthiazate. Also, if desired, other pesticides (pesticides, nematicides, acaricides, pesticides, fungicides, antiviral agents, attractants, antibiotics, plant hormones, herbicides, plant growth regulators, etc.), fertilizers, soil improvement materials, weak A reducing agent, a soil penetrant, etc. can be mixed or used together. In addition, phosphthiazate and the said other various components may respectively mix and process what was separately prepared, and may process what was prepared together.
