In this case, the trunk can be controlled by coating the trunk with a stone sulfur mixture in spring and autumn every year.
-
If a hazard is found, you can spray the trunk with a new set to kill the stem boring pests. It can also be applied to the root of the forest road fertilizer to prevent and initial control. Whether it is a tree trunk borer or a peach borer that harms the fruit, it is necessary to apply pesticides in time, and try not to spray pesticides 20 days before the fruit is ripe.

Adult insects are killed by hand. In the adult occurrence period from May to June, manual hunting is organized. on the canopy.
can be killed after using its feigned death vibration. It can also be used to trap and kill at night. Artificially kill insect eggs.
During the oviposition period or after the oviposition of the adult worms, the base of the trunk is examined, the oviposition groove is looked for, and the infested area is dug up with a knife; It can also be struck with a hammer to kill eggs and larvae.
Walnut trees. The drill worm on the main trunk is called the cloud-spotted longhorn beetle. The adult insect stage is generally in July, and it can be controlled by foliar spraying. It is the larvae that damage the trunk of the tree, and when insect droppings are found, a disposable syringe is used to inject the agent, usually 50 times the amount of cypermethrin.
That's it. The pruning of walnuts is generally in autumn, after the leaves turn yellow, the nutrients of the pruned leaves have been refluxed, and the cutting will not cause damage to the flow.
The borer worm of walnut trees can be controlled with 50 times more cypermethrin.
Suyun is available. Foliar spray control of bacillus.
Peach heart-eating insect control should be sprayed with insecticides when the buds appear during the flowering period, and sprayed three times every other week.
Walnut tree borborer is controlled with cypermethrin.

There are two main ways to kill the trunk borerworm. The first method: turn over the soil next to the tree, then sprinkle it with octactal sulfuric acid and Miller granules, and use it twice in a row; Second method:
Mix dichlorvos, trichlorfon and sugar water together and spray on the trunk where insects are growing.
-
After the borer worm appears on the trunk of the peach tree, diluted trichlorfon or dichlorvos and water in a ratio of 1:2000 with water, sprayed on the leaves or poured directly into the trunk. Red wasps can also be placed around the peach tree to kill the borrower worms in the peach tree.
When the situation is more serious, the soil around the trunk can be turned over and sprinkled with octanosulfuric acid powder**.
After the peach tree trunk out of the borer, you can buy insecticides such as borer, trichlorfon, dichlorvos emulsifiable concentrate, dilute the agent and water in the ratio of 1:2000, spray the peach tree with spray, and then pour the insecticidal solution into the trunk to kill the borer on the trunk.
In the process of reproduction, the red wasp will lay eggs in the eggs of the heartworm, and after the larvae hatch, the larvae of the red bee will parasitize into the body of the heartworm, resulting in the death of the heartworm.
I want to control the borrower in the trunk of a peach tree. The soil around the trees also needs to be properly turned. The soil around the trees can be turned over, and then evenly sown occult sulfuric acid and milol particles, and sprayed twice in a row to achieve the best effect.
It should be noted that in the daily maintenance of peach trees, it is necessary to ensure that the environment is ventilated and breathable, so that the peach trees can receive sufficient light. Management needs to be strengthened before rainy weather arrives. When the light is too strong, it is necessary to increase the amount of watering to prevent germs from invading the plant and allowing the peach tree to grow healthily.

Peach trees are planted all over China because of their strong ability to grow. Compared with other regional fruits, the yield is also relatively large. However, sweet and delicious peaches are threatened by pests and diseases, and eliminating pests and diseases from peach trees has become one of the major tasks.
Next, let's introduce how to get rid of pests and diseases in peach trees.
Agricultural control techniques for peach tree pests and diseases
1. Reasonable layout to prevent mixed planting of peaches and pears and avoid rampant harm of small solid pear insects. The larvae of the pear small solid insect generation mainly harm the peach tree generation mainly harms the fruit of the pear, and if two kinds of fruit trees are planted in one orchard at the same time, it will cause serious harm. Therefore, separation zones should be set up whenever possible.
2. Scrape off diseased tissues and warped skin. Peach trees often have branch diseases such as gum disease and rot disease, which can be effectively controlled by manually scraping the diseased tissue and then applying pesticides such as 843**.
3. Reasonable pruning and pruning of diseased and insect branches. Pruning of peach trees is divided into winter and summer pruning. When pruning in winter, you can cut off the branches harmed by the bulb scale and the mulberry scale, the branches where the grasshopper lays eggs and the diseased fruits and stiff fruits left on the tree.
One of the most effective ways to prevent and control the disease is to prune the disease, burn it intensively or bury it deeply.
4. Reasonable fertilization and irrigation. More application of organic fertilizer, reasonable application of chemical fertilizer, and timely irrigation can promote the growth of peach trees, make the tree healthy, and the damage of diseases and insects is light; On the contrary, the damage of pests and diseases is serious. In addition, peach trees are extremely waterlogging tolerant fruit trees, so they must be drained in time during the rainy season.
5. Remove dead branches and leaves, and pay attention to the hygiene of the peach orchard field. After the peach tree has fallen leaves, combined with winter pruning, it can remove the dead branches, fallen leaves, weeds, etc. in the peach orchard in time, and bury them deeply or burn them intensively, which can eliminate the source of overwintering insects. In addition, it is necessary to pay attention to the hygiene of peach orchards during the growing season.
6. Sweet and sour liquid traps adult insects. Use sweet and sour liquid into a bowl or small jar to act as a trap. Sweet and sour liquid recipe:
Brown sugar, 1 part vinegar, 10 parts water, and a small amount of liquor are ready. When using, hang the trap on the tree with wire or rope, remove the dead insects every day, and replenish the sweet and sour solution to the original water line.
7. Wrap the trunk around the straw. Using the habit of laying eggs on the trunk of the tree or overwintering under the warped skin and in the crevices of the skin, the peach-necked beetle, the pear heartworm and the hawthorn leaf mite are used to entangle the grass on the trunk to attract these pests.
8. Black light traps and kills adult insects. The installation of black light in the peach orchard can trap and kill a large number of peach borers, leaf rollers, peach leafhoppers and other adults.

There are white bugs in the stems of the peach tree, which are the larvae of the red-necked longhorn beetle. Peach tree red-necked longhorn beetle control method:
1.Adult worms are caught manually. During the period of 6 and July, the adults are at their peak and can be captured manually.
Hook a long bamboo pole with an iron hook to the branch and shake it vigorously, and the pests will fall to the ground one by one and catch them one by one. Manual capture is fast, effective, labor-saving, drug-saving, and does not pollute the environment. After the pupa of the pupa is feathered, during the adult activity in June and July, the habit of the adult having resting branches from noon to 3 p.m. can be used to organize personnel to capture in the orchard, which can achieve better control results.
2.Whiten the main branches. 4 During May, i.e. before the adult emerges, the trunk and main branches can be coated with a "white coat".
Crack and void in the bark to prevent the adult from laying eggs. Taking advantage of the habit of being afraid of white, the main trunk and main branches of the peach tree were painted white before the occurrence of adults, so that the adults did not dare to stay on the main trunk and main branches to lay eggs. Whitening agent can be used quicklime, sulfur, water, press 10:
1:40 ratio for preparation; It is also possible to coat the branches with the sediment of the stone sulfur mixture of the year.
3.Kill S. in advanceLarvae.
The larvae hatched before September are eaten under the bark, and at this time, they can look for fine reddish-brown insect droppings on the main trunk and main branches, and once they find insect droppings, they use a sharp knife to cut the bark to kill the larvae. Branches can also be inspected in the spring of the following year, and once reddish-brown sawdust-like droppings are found on the branches, the larvae in the xylem can be dug out with a sharp knife to kill S.
4.Methods of drug prevention and control. Depending on the growth period of the pest, different methods are taken.
During the peak stage of adult occurrence and the larvae just hatching in 6 July, spray 1000 times of 50% borer pine emulsifiable concentrate or 10% imidacloprid 2000 times on the tree body, 7 10 days 1 time, spray several times. or wormhole application. Older larvae have bored into the xylem, and spraying has no effect on them, and can be treated by wormhole application.
Clean the fecal hole on the trunk, fill the hole with dichlorvos tampon, use a disposable medical syringe, and pour 50% dichlorvos 800 times or 10% imidacloprid 2000 times into the cavity, and then seal the orifice with mud.

I don't know how many generations happen a year where you are, and three generations a year where I am. The first time is during flowering. Before the ovary is allowed to form in the flower, the larvae have already entered the young fruit.
This is the first time. It is not very harmful to peach trees, but it is very harmful to plums. The second time is from late April to early May.
This was the most harmful to the peach tree. When you notice that the new shoots of the tree are wilting, the larvae are still in the new shoots of the tree, not yet in the fruit. This is to be prevented quickly.
You can use BT (Bacillus thuringiensis) or Kangkuan to prevent and control it, and the effect is very good. The third time is from late June to early July, and the characteristics and control are the same as the second time, and other pests and diseases can be controlled at the same time. The drugs can be used alternately, and the effects are more than 30 days, so that your peach trees are pest-free for a year.
