Description

Control Method of Plane Woodworm Beetle and White Fire Moth Using Bestial Infusion Method

Since this is an open matter, no full text was included.

The present invention relates to a method for controlling the detriment of extreme Planus plants at home and abroad.

More specifically, the present invention is a method for controlling the tree beetle (Corythucha ciliata. Say) and the white worm moth (Hyphantria cunea) that inflicts the hawthorn plants by using the infusion method of the invasive insecticide. The present invention relates to a method of controlling the pests in which a chemical solution moves to a leaf along with sap to inject a leaf by injecting a systemic insecticide into a common namely used tree.

According to the conventional roadside protection method, the sprayer is mounted on the vehicle and the insecticide is sprayed three to four times a year, but the control means by the foliar spraying method does not obtain satisfactory results for the plane tree beetle.

White moths have long been infested with foreign species and now have over 160 species, especially in plague trees. In Korea, pesticides have been sprayed in June and August to control them.

Plane tree bug is a kind of shield bug such as pear tree bark and azalea tree bark. It is believed to have been buried when importing timber or seedlings from North America, but it has not been identified yet. It is becoming more common and it is spreading to the plane tree of the whole country recently. In the early stages of damage, the central part of the leaf becomes discolored and gradually becomes brown, and in severe cases, the leaf is pushed backwards and the entire tree becomes brown and even early deciduous leaves appear.

As a result of the study of the present inventors, the life history of the beetle shield beetle wintered in bark, deciduous leaves, weeds, etc., and in May of the following year, began to live while absorbing the juice from the back of the leaf of the plane. The number of eggs spawned is around 15 and 15 days after hatching, it becomes adult about 20 days after hatching. Therefore, the shield beetle occurs 3 to 4 times a year, the breeding rate is very high, and after July, adult, egg, and larvae are mixed. In Seoul, adult insects appear most frequently in late August and late September, and the damage is severe during the oily season. Conventional remedies are sprayed with foliar sprays of organophosphorus, carbamite, and pyrethroid-based chemicals in Seoul and local governments. In addition, because many passersby pass through the leaves, the insects that cannot be evenly sprayed on the leaves do not die because the insects do not directly touch the body. As a result, the remaining insects multiply rapidly and the affected area continues to spread.

Therefore, the damage is worsening due to the selection of drugs, the timing of spraying, and the lack of spreading methods, and the spread of roadside chemicals in urban areas causes pesticide pollution, such as toxic pesticides on passers-by and passing vehicles. The situation is being sprayed indiscriminately even the natural enemy of worms.

The present invention has been made to solve the above problems is to provide a method for effectively using the penetrant pesticides.

Still another object of the present invention is to provide a method of effectively controlling the plane beetle shield and white fire moth by using the penetrating insecticide in the liver.

In order to achieve the above object, the present invention selects a penetrant pesticide to control the Planus beetle worm and white fire moth rapidly spreading on the Planus plant, and in the case of injecting the same, the amount of the drug suitable for the size and timing of the tree This was achieved by investigating the size and number of perforations, follow-up care, and timing of drug injection, which are convenient for work and minimize damage to the tree.

The present invention comprises the steps of drilling with a plane of the plane tree; Injecting a penetrant pesticide; It consists of blocking the perforated hole and investigating the control effect.

When explaining the specific method of the present invention step by step.

Step 1: drilling the trunk

Drill a 2 ~ 30mm diameter pipe between the planes of the plane tree to make a depth of 20 ~ 300mm.

Stage 2: Insecticide Injection

Inject one or more pesticides into the drilled hole. Systemic insecticides that can be used at this time include phosphamidon, formathion, vamidothion, monocrotophos, demeton S-methyl, acephate, carbofuran, Furathiocab, benfuracarb, carbosultan, pymetrozine, aldicarb, imidacloprid, and acetamiprid. The pest is controlled by injecting 0.02 to 1.2 g as the active ingredient.

Step 3: plug the hole

After injecting pesticides, stoppers made of paper, cloth, tack, cork, rubber, styrofoam, PVC, silicone, sponge, polyethylene or EVA to prevent germs or pests from entering the holes and rotted Coating is done with a coating agent such as a cord or paint.

Thereafter, whenever the insects occur, administration of the invasive insecticide through a stopper with a syringe or the like has the advantage of simply controlling the pest as well as other pests.

At this time, the stopper may be used in any form other than those mentioned above and does not limit the scope of the present invention.

Example 1

Actual control experiments were conducted to investigate the control effects of the present invention.

Insecticide injection time, perforation depth, diameter of perforation, and dosage per injection were varied according to the thickness of the trunk tree, the size of the water pipe, and the pruning degree. Each year, pruned trees have 1-12 holes in the lower part of the trunk, depending on the diameter of the chest, and 2 ~ 90g of 2-12g per hole were injected with a permeable insecticide (Table 1).

Control Example

Table 1

The above embodiment can be added or subtracted according to the pruning state, and trees left without pruning should increase by about 50 to 100%. After the insecticide was injected, a stopper was made of cork, styrofoam, rubber, sponge, or PVC, and then covered with a coating agent.

Thereafter, whenever necessary, the medicine was injected into the syringe through a stopper.

As a result of investigating the control effect through the above embodiment, the method of the present invention, the leaf beetle that is rapidly spreading in the plane of the tree, the larvae after 2-3 days, the adult larvae after 3 to 5 days Killed. The eggs die after hatching, resulting in 100% complete control, especially white fire moth and plane beetle.

Therefore, the control method of the present invention is economical and effective by significantly reducing labor costs compared to conventional foliar spray control methods, and in the case of roadside trees, foliar spraying of toxic pesticides reduces pesticide damage to pedestrians or vehicles and obstructs the flow of traffic. Not only does it reduce the destruction of the ecosystem due to foliar spraying and at the same time prevents the invasion of the liver, it is a very useful invention in the plant control industry because it has an excellent effect of preventing the liver from rotting.
