What to do if the trunk is eaten by insects, and what to do if there are insects in the trunk of the

How to deal with insect eaten trunks:

Diseased branches should be pruned in time, and the pruned parts should be burned to prevent secondary infection;

Spray 1000 times of 90% trichlorfon or 25% of tetradimerazine as a suspension agent to kill pests and eggs;

After killing the pests and their eggs, the surface of the trunk is also coated with a layer of lime milk to prevent pests and diseases.

1. Spray insecticide: spray chlorothalonil every 1 week on the trunk. 2. Prune:

4. Maintenance management: reduce the amount of watering in the rainy season and bask in more sunlight during the day.

1. Spray insecticides

After the trunk is eaten by insects, it should be sprayed with pesticides, sprayed every 1 week to kill the eggs, and in the process of breeding trees, it is necessary to regularly spray disinfectants and insecticides to avoid pests from multiplying in the branches.

2. Prune:

In order to reduce the damage to the plant, after the trunk is eaten by insects, the rotten and insect-infested parts need to be cut off, and then the insects are manually caught and burned together, so that the eggs do not crawl into the healthy branches, causing the whole plant to be eroded by pests.

3. Apply quicklime

After killing the eggs, you need to apply a layer of quicklime on the surface of the branches, which can not only beautify, but also prevent insects, and in the process of cultivating trees, you can also sprinkle lime in the soil to inhibit the breeding of insect eggs.

4. Maintenance management

When cultivating trees daily, it is necessary to prune frequently, and cut off the diseased leaves and yellow leaves in time to avoid bacterial breeding, and the plants should be exposed to more sunlight, and the rainy season should reduce watering, so as to avoid excessive humidity and rotten roots.

Endophytic insects in the trunk of locust trees, mainly larvae of longhorn beetles, can be controlled with pesticides:

1. You can put 30 50 times 50 times 50 dichlorvos in the new fecal hole of the tree trunk.

Emulsifiable concentrate or 40 cotton balls of dimethoate emulsifiable concentrate, or put in 1 4 pieces of aluminum phosphide, and then seal the insect mouth with mud for killing.

2. It can also be punched in the trunk for prevention and control. For trees with tall canopies and difficult spray control, 40% dimethoate solution and 20% imidacloprid were injected into the trunk.

It can control the adults and larvae of longhorn beetles. The method is to drill an oblique hole deep into the xylem at a trunk 30 cm from the ground, and the dosage is generally milliliter cm DBH. It can also be injected directly from the fecal discharge hole.

3. Whitening the trunk: The eggs laid by the star beetle are mostly in the lower part of the trunk, and the whitening coating (quicklime) can be applied to the trunk.

1 serving: sulfur powder.

1 part: 40 parts of water), which has a taboo effect on adults.

If there are insects in the trunk, you can use pesticides such as organic or vehicles to irrigate the roots, or spray the trunk.

Summary. 1.Trunk coating.

To control aphids, goldenrod insects, red spiders and scale insects on pine trees such as willow, black locust, hawthorn and cherry, the trunk can be applied at a height of 2 meters from the ground, and the control effect can reach more than 95%. This method is simple and easy to use, and it is more effective if you wrap a green or blue plastic paper on the application area. The plastic paper is removed after 5 to 6 days after the effect of the drug is manifested to avoid rotting in the bandage.

What medicine is used for insects on dry trees on the house.

1 Paint treatment For some corners that have not yet been damaged, use raw tung oil, shellac paint or varnish and other coatings to brush the surface of the wood, which can isolate the moth from the air and achieve the purpose of moth-proofing. Note that all should be applied evenly. 2 pesticide treatment When the wood is moth-eaten by insects, dichlorvos and mu round water can be used to prepare the liquid medicine in the ratio of 1 5, spray Wei Xun with a sprayer, let the liquid infiltrate into the wood, to spray 3 times 5 times in a row, after 8 hours of Xunshan collapse, it can kill all the moths.

Methods for removing borers from tree trunks.

You can use hook killing, assassination, poisoning, painting and other methods to solve the insects in the trunk.

Is there any medicine that works.

One day, the wood powder from the worm drill fell.

Hook killing method: Mainly for the longhorn with straight insect paths. Inspect the tree and find fresh insect droppings, and kill them with wire hooks.

Assassination method: Mainly aimed at the first filial piety to pick up the spiral insect channel of the Ji Ding Jia. In general, the inlet is at an angle of about 45° to the xylem larval latent site, which can be pierced with a sharp drill.

Poison method: a more general method of careful keying, and does not hurt the tree. Spray pyrethroid mosquito killer on the air outlet for 1 second, and then plug it, which can basically be killed.

Brushing method: Mainly for silverfish, you can use an insecticide with good contact killing such as cypermethrin to brush the branches of the tree.

Dip 5-10 times of 80% dichlorvos EC or 40% dimethoate EC with cloth strips or waste paper, and stuff them tightly into the cavity; Or use a veterinary syringe to inject the liquid.

It is also possible to use 56% aluminum phosphide tablets (about 3 grams per tablet), divide them into 10-15 small grains (each serving of York), stuff one small grain into each cavity, and then seal the hole with soil.

Use a poison swab to insert a cavity to poison the larvae (the poison swab can be made with zinc phosphide, peach gum, oxalic acid and bamboo skewers).

Hook larvae: When the larvae are still eating under the cortex of the root neck, or when they are not deep in the xylem, they should be hooked in time.

Simple prevention and control: the use of woven bags for packaging fertilizers, etc., after washing, cut into a long strip with a width of 20-30 cm, before the star cattle lay eggs, in the main part of the easy to lay eggs, with the cut braided strip wound 2-3 times, each circle between the connection does not leave a gap, and then with hemp rope binding, the prevention and control effect is very good. Through bandaging and barrier, the longhorn beetle can only put the eggs on the braiding bag, and then the eggs will lose water and die.

**Damaged tree: During the peak period of root growth from Qingming to Lixia, choose a sunny day, dig up the root neck soil clod of the tree infested by Xingtianniu, scrape off the wound residue with a sharp knife, make the wound appear fresh color, apply rooting powder at the wound (it can also be coated without coating), and then pile the manure around the wound, and cover the film block, the upper end of the film block is tightly tied with hemp rope against the trunk, the lower end is spread on the fertile soil, and finally covered with the excavated soil and pressed. Soon, the wound produces a callus, re-sprouts new roots, and the plant regains its vitality.

1. Apply pesticides around the trunk.

Targeted measures are taken to apply pesticides directly to the trunks of insect-growing trees in the same proportion. Some ordinary insects can't stand the smell of pesticides or some insecticides or eat them, and the insects will escape or die directly, which has the effect of killing insects.

2. Pour pesticides into the wormholes.

A more effective way is to drill a hole in the trunk of a tree with insects connected to the wormhole, open the proportion of pesticides (insecticides), and then pour the prepared pesticides directly into the wormholes. With a little more fertilization, the trunk will grow back in no time. If the insects are not killed in time, the whole tree or the trunk with insects will slowly turn yellow and dry out.

5. Hang a special sticky insect board under the canopy to trap and kill flying insects to consolidate the effect of drug control. This is mainly to take advantage of the "yellowness" and "blueness" of pests.

This kind of insect is called dry boring pests, mainly including longhorn beetles (mulberry beetle, star beetle, etc.), gidding insects, etc., mainly using chemical control methods and pesticides to control. The pesticides used are dichlorvos, aluminum phosphide, etc., and a cotton ball is dipped in a little pesticide or made of poison sticks (pesticide poison sticks that can also be bought in pesticide stores) are stuffed into the cavities formed by the hazards, and all the cavities are sealed with wet mud to kill pests. Some of the pests on the branches are combined with winter pruning, which cut off the branches with insects and burn them intensively, which can reduce the occurrence of insect pests in the second year.

Treatment methods for insect moth-eaten trunks: diseased branches should be pruned in time, and the pruned parts should be burned to prevent secondary infection; Spray 1000 times of 90% trichlorfon or 25% of tetradimerazine as a suspension agent to kill pests and eggs; After killing the pests and their eggs, the surface of the trunk is also coated with a layer of lime milk to prevent pests and diseases.

Inspect the branches of the tree for signs of insect decay, and prune off the diseased branches immediately if they are found to be rotten or moth-eaten to prevent pests from invading other healthy parts. For the pruned part, it is necessary to concentrate on treatment, and the incineration method is generally used to prevent the breeding of pests.

Spray different pesticides for different pests, if grubs, white bag moths and other pests can be sprayed with 1000 times water of 90% trichlorfon for control. Be careful not to use it in combination with alkaline drugs, as chemical reactions will occur and produce a large number of toxic substances that endanger the environment and human health.

There are also broad-spectrum pesticides that can be used, such as tetramitezine. It is an organic nitrogen heterocyclic insecticide, and has low toxicity to humans and animals, and generally uses 25% suspension agent for spraying. This medicine lasts for a long time, should not be used more than 2 times a year, and generally takes effect 7-10 days after the drug.

Quicklime is mixed with water at a mass ratio of 1:7 to make lime milk. After killing the pests and their eggs, the trunk is also coated with a layer of lime milk.

Lime milk has the effect of denaturing proteins, and it can prevent pests from attacking for a long time when applied to the trunk, and it is a good medicine for dealing with insect moth.

After the tree grows insects, you can apply a whitening agent to the trunk to prevent the pests from continuing to reproduce and grow on the trunk, you can also water the diluted liquor solution into the planting soil to eliminate the eggs and pests in the soil, and you can also buy insecticides directly from the market and spray them on the trees that grow insects to eliminate pests.

1. Apply whitening agent

After the tree grows insects, you can apply a whitening agent to the trunk. Because most of the pests on the tree are hatched from the eggs in the cracks in the bark, after the pests appear, apply a whitening agent to the trunk to prevent the pests from continuing to reproduce and grow on the trunk, so as to achieve the purpose of eliminating the pest.

2. Water the liquor

After the tree grows insects, you can also water liquor on it. First of all, you need to prepare a glass of liquor, mix it with two glasses of water, and then pour the mixed solution in the planting soil, you can eliminate all the pests in the soil, and the roots of the tree absorb the water containing the liquor, which can also improve the resistance to insect pests.

3. Use vinegar

After the tree grows insects, you can also use vinegar on the plant. That is, you can directly use a cotton swab or cotton ball, dip it in vinegar, and apply it to the trunk of the tree to carefully carry the area where the pests are active, and the pests can be eliminated. However, this method is only suitable for trees with a height of less than two meters, and it is not possible to remove pests from tall trees.

4. Spray the agent

The easiest way to do this is to spray the trunk of the tree. First of all, you need to buy a special dimethoate insecticide from the market, then dilute it according to the proportion on the package, and spray it on the trunk of the tree where the pests are active, spraying it once every other week, and after three consecutive times, you can eliminate the pests.
