How to cure the woodworm in the apple tree, and how to cure the woodworm in the fruit tree

The longhorn beetle, also known as the woodworm, is one of the main diseases that harm the branches of fruit trees in recent years, and the situation is serious, and there is a danger of destroying the garden. The insect occurs in 2 3 years, harms the xylem and the medulla, and there is a row of fecal holes at certain intervals in the infested part, and the insect path is straight, and the reddish-brown feces are discharged and accumulated on the ground.

The original method was to use 100 times dichlorvos solution to fill insect eyes, or use aluminum phosphide to make a poison swab and stuff it into the penultimate or second fecal hole, and block all the fecal holes with wet mud. However, it did not work well.

A new recipe can be used: per kilogram of water, add: Roushui Tong 3 5 ml Dexkop 1 bag (g) Jinlis 3 5 ml Dichlorvos 20 ml (after the fruit tree leaves fall to before germination, use dichlorvos 50 times after germination) A small spoon of sugar.

The application effect is particularly good after multi-point test. In early spring, the medicine was poured thoroughly, and now the insect eye has healed.

The "drill woodworm" is the larvae of the longhorn beetle. You can inject 5 10 ml of 10% dichlorvos solution into its excrement hole (where fresh wood chips have fallen), and then seal it with soil, and the bugs inside will die

It's too simple, just use the cooking oil to drip into the hole of the wood worm, and the ants like to eat peanut oil the most, so let the ants introduce it into the hole, and then the ants will haha! It's better to drop a little more oil and flow it under the tree. Give it a try!!

I've used it and it feels good...

You mean the Celestial Cow, right? Inject medicine into the wormholes. Specifically, check the prevention and control methods of the longhorn beetle on the Internet.

1. Pesticide spraying or brushing.

There can be dichlorvos, phosphine, dimethoate, insecticidal squint, pine borer, phoxanthion, phosphophos, insecticidal net, pharmacarb, dimethoate, fluoroacetamide and so on spraying or brushing the trunk.

2. Pesticide injection method.

With 20 times of 80% dichlorvos emulsifiable concentrate, before and after the Qingming Festival and the autumn equinox, where there is fresh insect feces on the tree body, use iron wire to clean the sawdust-like insect feces in the hole, and inject the liquid with a syringe without a needle. Then seal the wormhole and the hole near the wormhole with clay, and remove the wood chips from the ground to check the control effect.

3. Mothballs killing method.

Stuff the crushed mothballs powder into the worm holes, with a dosage of 1 5 1 4 grains per hole, or you can dip the mothballs in alcohol, gasoline or diesel with absorbent cotton and stuff them into the holes with clay to seal the orifices to smoke the longhorn beetle.

4. Plant bait trees to trap and kill.

The adults have a strong selectivity to tree species, and can take advantage of this habit to plant a certain number of bait trees to attract the adults of the longhorn beetle for pesticide or artificial control and adult occurrence monitoring.

5. Strengthen garden management.

Timely pruning and treatment of insect dead branches to promote the vigorous growth of fruit trees and reduce the damage.

**The way to drill wood worms in apple trees is to add 3-5 ml of soft water, Kedekop, 3-5 ml of Jinlis, 20 ml of dichlorvos (after the fruit tree falls leaves and before germination, use dichlorvos before germination, and use 50 times the liquid of Anmin after germination) and a small spoon of sugar, mix well and pour into the insect eyes.

Apple trees are deciduous trees, usually up to 15 meters tall, but cultivated trees are generally only about 3-5 meters tall. The trunk is grayish-brown, and the bark has a certain degree of shedding. The fruit is generally red in color, but it depends on the variety.

The fruit of the apple tree is rich in minerals and vitamins and is one of the most commonly consumed fruits.

The flowering period of apple trees depends on the local climate, but it is generally concentrated in April and May. Apples are cross-pollinated plants, and most varieties do not produce fruit and fruit on their own. Generally, apples do not begin to bear fruit until 2-3 years after they are planted.

The length of the fruit growth period is generally 65-87 days for early-maturing varieties, 90-133 days for medium-ripening varieties, and 137-168 days for late-maturing varieties. Under normal circumstances, apples can have a lifespan of 15-50 years after planting.

Apple's presentation

The apple is a familiar fruit, it is chubby, and has a harvest red color all over its body. Apples are a fruit that grows in the north. Idioms"Fruitful"That's what it is.

Flowering or transporting apple trees deciduous trees, up to 15 meters high, generally 3 5 meters tall under cultivation conditions. The trunk is grayish-brown, the old bark is irregular, and the twigs are smooth. The leaf order is single-leafed alternate, elliptical to ovate, with serrated margins.

The flowering period of apples varies greatly depending on the climate in different places, generally in April and May, each flower bud has 3 7 flowers, and the center flower blooms first. Umbel inflorescence, petals white, pink when bracting, stamens 20, columella 5. Apple trees begin to bear fruit 2 to 3 years after planting, and the fruit is a kernel fruit, and the color and size vary depending on the variety.

Apples love light and prefer slightly acidic to neutral soils. There are more than 7,500 known varieties of apples. Good Breed:

Red Star Series", "Red Fuji", "Jonathan" and many more. In addition to fresh varieties, there are also cooked apples. Because the fruit acid of apples has the effect of retaining moisture, it is suitable for baking.

<>**Apple tree drill wood worm can refer to the following method: add 3-5 ml of soft water, Kedekop, 3-5 ml of Jinlis, 20 ml of dichlorvos (after the fruit tree leaves fall to before germination, use dichlorvos before germination, and use 50 times the liquid after germination) and a small spoon of sugar, mix evenly and pour into the insect eye.

Control method 1, manual killing of late June to August under the shed Sun judge adult occurrence period, every evening to patrol the orchard, catch adults. Adults are inactive during the day, but they can vibrate the trunk to make the insects fall to the ground to kill. The second is to make self-made tools to stab the larvae, and the lowest 1 new fecal hole can be selected during the prevention and control, and the moths will be pulled out, and then the steel wire or metal needle will be inserted into the hole to hook or stab the larvae.

Article **52, drug control larval occurrence period, for the new fecal hole, the following agents can be used: 40% chlorpyrifos 1000 times, 20% butylthiol carbofuran 1500 times, deltamethrin 1500 times, 80 dichlorvos EC 100 times, 10 imidacloprid wettable powder 500 times with veterinary syringes injected into the cavities, a few days after application, timely inspection, if there is new fecal discharge, should be timely treatment. Each well is filled with a maximum of 10ml of liquid medicine chain modification, and then the hole is sealed with wet mud, and the insecticidal effect is very good.

At the same time, in July and August, during the oviposition period of adults after each rainfall, combined with spraying on the tree, mixed with 20% butadisulfone carbofuran 2000 times or deltamethrin 2000 times, the main stem and branches should be sprayed finely when spraying, and the larvae should be eliminated before the egg stage and the initial hatching before the holes.

<> agricultural control: keep the orchard clean, sweep the residual branches and leaves in time, cut off the branches and fruits that are affected by pests and diseases, and then burn or bury them deeply. Chemical control:

In the first generation of larvae hatching stage, mid-May adult occurrence stage, late May egg peak stage, the canopy was sprayed with Uranus emulsifiable concentrate or 30% peach net (1500 times liquid), with an interval of 10-15 days each time.

July is the period when adults are in full bloom, and you can use the morning after the rain or the evening when the adults appear in large numbers to manually kill, which can reduce the pest reproduction base and kill an adult.

If the larvae have penetrated deep into the branch and there is a fecal hole, find out the lowest fecal hole, and use a poisonous bamboo skewer or a small wooden stake to block the orifice, and the larvae can be killed.

Wood drill has become a major pest of apples, peaches, apricots, plums, cherries and other fruit tree branches. On June 19, after the rain, the sky was clear, and the adult red-necked Mulberry beetle was found to lay eggs in the field.

In July, the larvae will feed downward under the skin and in the xylem of the branches, and bored 1 hole at intervals to ventilate and excrete debris at intervals, weakening the tree at least and dying in the worst cases. July is the peak period for adult oviposition and larval orange infestation.

The apple borer worm makes the leaves densely covered with yellow spots in the early stage, turns red in the later stage, and the leaves are wrinkled and uneven, followed by the damage to the fruit, so that the apple yield is greatly reduced. The main reason for causing apple borer is that the environment of the fruit tree is not clean, and it can be sprayed on the trunk with high-efficiency cyfluthrin, or injected directly into the wormhole.

Apple heartworm symptoms.

Apple borerworm, also known as Mulberry Bull Royal Mountain Crack, is mainly distributed on apples, pears, peaches, apricots and other fruit trees. In recent years, the occurrence of apple trees is serious, mainly because the larvae drill holes in the main trunk and main branches, and the degree of damage to the fruit is secondary, and it can cause the death of apple trees in severe cases.

Heartworm damage.

The leaves are densely covered with yellow spots at the beginning, turn red in the later stage, the leaves are wrinkled, bent longitudinally from the edge to the back, the leaf tissue thickens, and finally dries out, turning black-brown, and does not lose leaves in winter.

Causes of apple borrower.

The apple borer worm is caused because the environment of the fruit tree is not clean, or the fertilizer is not well absorbed.

What medicine is good for apple heartworm.

Apple borer can be cured, you can use cyfluthrin to spray on the trunk, add silica gel is better, pay attention to be sprayed evenly, thoroughly.

**Apple heartworm effect.

**Drill worm apple can be applied to the wound with copper oxychloride suspension or carbendazim solution to avoid bacterial infection.

Apple heartworm control methodThe best time for heartworm control.

**It is best to apply the only medicine when the apple borrower has just laid eggs on the trunk of the tree, and inject the agent directly into the wormhole.

Drill heart worm ** method.

Use the phototaxis of apple borrower to trap and kill, in early May and early September, install an insecticidal lamp for every 15 20 acres of orchards to trap and kill adults.

Cardioworm precautions.

**Apple borer beetle should pay attention to keep the orchard clean and clean up the fruit drop in the ground in time. In winter, fill the tree hole with soil, scrape off the trunk and bark, burn the grass ring and the bark to remove the insect source, and brush the main part of the fruit tree with mortar and a certain proportion of insecticide.

Drill wood insect damage prevention and control methods: Trichlorfon or dichlorvos can be injected with a needle, and the hole can be sealed with mud after beating, which can be used to kill the drill wood worm. You can also use cotton dipped in the pesticide dichlorvos, stuff it into the insect eye, and seal it with mud or tape on the outside to kill the wood worm inside.

In addition, fruit farmers can also spray insecticides such as imidacloprid into the orchard in the process of spraying the agent into the pest hole to kill the wood drill insects.
