There are a lot of borers on the cherry seedlings, how to solve them?

Adult fruit flies begin to lay eggs on the fruit in late May each year, laying their eggs under the skin of large cherries, and when the eggs hatch into larvae, these larvae feed on the surface of the fruit to the core. It will come to lay eggs, and the eggs are laid directly under the peel, so when the fruit is ripe, these larvae are still not ripe, then they will be eaten by us, after all, when we eat cherries, the larvae of a fruit fly are different from the "maggots" in our usual impression, it is close to flies, but not flies, it is a fly that lives on ripe fruits, and it may appear on various ripe fruits. Fruit flies are very sensitive to pesticides.

<> not only cherries have small white worms in them. Even mulberries and apricots have small white worms, and mountain chestnuts also have two small white worms in the early (small) fruit period, but the chestnuts have no two small worms as they grow! And cherries.

Mulberry seeds. The more ripe the apricots, the more fruit fly larvae resemble maggots, eating in the fruit, and there are needle-tip-sized cavities on the fruit surface, which are hollow, and the fruit is rotten, completely losing its commodity value. Consumers feel particularly uncomfortable when they see the white wriggling larvae, which seriously affects the sales If the fruit has heartworms in May every year before the fruit is ripe, it is necessary to continuously spray the medicine to prevent the heartworms, and the weather is hot in mid-May, the heartworms will crawl out of the ground, and the prevention will start spraying drugs in May.

Fruit flies may also lay eggs in fruits, so people are easy to eat these white insects when they eat, and even soak them in water for a while, there are a lot of white insects floating in the water Fruit flies are a kind of high-protein, nutritious insects, unlike the houseflies we usually see, the larvae are in a pollution-free environment from birth to growth, and rarely carry germs. In addition to cherries, cherry trees with high sweetness such as bayberry, strawberry, mangosteen, orange, orange and so on are relatively resistant to disease, and fruit fly larvae are rare, but in recent years, consumers have an increasing demand for cherries and tend to buy cherries with more sugar and sweeter taste, making this large cherry widely cultivated.

There are a lot of borers on the cherry seedlings. This should be disinfected and sprayed. If these borers are not treated in time, they will cause a bad harvest of cherry seedlings.

It is necessary to spray the cherry seedlings with some pesticide in time, so that this situation can be avoided.

1. When aphids occur sporadically, you can use a brush dipped in water to gently brush off and kill them. 2. When the number of aphids is large, it is necessary to spray in time. There are many pesticides to control aphids, such as spraying 1000-1500 times of 40% dimethoate or 80% dichlorvos emulsion, or spraying 1000 times of rotenin, or 60 times of lime water (plus laundry detergent), etc.

3. The control of aphids can be controlled with drugs such as imidacloprid, thiamethoxam, and dimidoxam; Drug control of aphids, pay attention to the alternating use of drugs, aphids with one drug for a long time, aphid resistance will appear. 4. Pyrethroids can be used to control ants, such as bifenthrin, cypermethrin and other drugs.

Red cherries are a delicious fruit that everyone loves, their beautiful appearance, sweet and sour taste is very lovely, and many people now have a cherry tree planted in their homes.

In spring, the cherry blossoms of the trees are gorgeous, and when they bear a red fruit, it is mouth-watering.

Because of the delicious taste of cherries, some pests also like them, and cherry trees are particularly susceptible to insect infestation, especially their roots.

Like some stinging sea worms.

Their breath prolongs the breath and pierces the leaves of the cherry tree when the stone is taken, and the fruit absorbs the sap inside, which can cause damage to the tree.

And red spiders.

These spiders lurk in swarms on the leaves and branches of the cherry tree, and when they spread, they become a large patch, and when it is serious, the leaves of the whole tree will wither and fall.

We can use artificial methods to control these pests, and we can scrape off some of the dry skin of the branches before they germinate, and burn them all in one place.

You can also spray a time relaxation agent about the degree, and wait until 1 or 2 weeks after the cherry blossoms wither, it is these larval mites.

During the active period, we can spray some mites and so on.

Especially when the fruit tree is dormant, brush your teeth with some stiff bristles to eliminate all the overwintering females on the branches, and some of the branches that are infested by the insects.

These pests are really like wildfires that can't be burned out, and the spring breeze blows and grows again.

All their eggs must be eliminated en masse, so as to prevent them from growing more.

In the early stages of these larvae, we can use their social habits to hunt and exterminate.

The most common and rampant ones I think are the leaf-curling moths, which eat the growth points of the new shoots of the leaves, causing the leaves to curl up in a ball.

Large cherry trees are particularly susceptible to a kind of root cancer, which is a root tumor disease, which generally occurs in the rhizome under the table, and some lateral root joints, etc., these germs will invade from the wound, and eventually form tumors, and these diseased sketches may not be obvious in the early stage, but as the tumor grows larger, it will occur short and weak, and the leaf color will be yellow, etc.

Therefore, when we select seedlings, we must prohibit the selection of some diseased seedlings, and do not trauma the rhizome and nearby roots when we plough.

Some pesticides should be sprayed in a timely manner, and a large number of pesticides should be seen especially at this stage of pollen dissemination, so as to ensure that there will be no more pests and diseases in the process.

For this insect infestation, the best way is to use imidacloprid solution for root irrigation, which is generally effective in one time.

Pesticides should be sprayed in a timely manner, and they must be watered more often and ventilated to prevent pests.

In fact, cherries are very good to manage, generally in the month after the fruit to reduce the management of water and fertilizer to prevent the seedlings from growing, about September, that is, a month before the winterWhen it is reduced to minus 5 degrees to 2 degrees Celsius, if the growth of cherry trees is weak, or when the nutrients stored in the old and young trees themselves are insufficient, more than 98% of the flower buds will be frozen to varying degrees. Even if the flowers bloom, they will fall off early due to the formation of separation at the base of the stem, which seriously affects the cherry fruit set. Watering promotes flowers and is not good to serve.

<> but as I am doing professional greening management, there is still a set of relatively perfect theory and experience technology for the planting and management of cherry trees, and the problem of low fruit setting rate of cherries is also a common problem for fruit farmers. This is a symptom of severe boron deficiency. Severe boron deficiency can greatly affect the normal growth of cherry leaves, flowers, fruits, roots and stems.

During the growth process, the external morphology of the cherry plant is abnormal.

Cherries are boron deficient and only bloom but do not bear fruit. Under the influence of low temperature, the probability of frost damage to flowers and fruits in strong cherry trees is only accounted for, while the cherries in weak trees are as high, that is to say, nutrition has a great impact on the flowers and fruits of cherries. If the nutrient storage is insufficient, the tree is poor, the flower buds are thin and shriveled, the quality is poor, and the flower drop is serious.

Scientific and rational use of plant growth regulators!

Even bad weather doesn't affect pollination! One thing to note when using fruit set is that it must be fertilized in autumn and fertilized early! Fertilizer must be fed enough and fed!

Also, be sure to comb the fruit! If you need technical information, you can follow me and send me a private message. The quality is not good, which is mainly reflected in the lack of nutrient reserves, how to work hard if you can't eat enough, so there will be only flowering and not fruiting or a large number of fruits.

Pay attention to the autumn application of basal fertilizer, which must be organic fertilizer, change the usual single chemical fertilizer, apply less nitrogen fertilizer, and increase phosphorus and potassium fertilizer.

Salt washing. 1. Rinse off the spoils on the outside of the cherries with water and soak them in water for five minutes.

2. Fill a basin of water, it is best to soak all the cherries, add an appropriate amount of salt according to the amount of water, stir the salt water well, and take a little salty taste as the best.

3. Soak the cherries for 15 minutes, then rinse both sides with water, dry and serve.

Function: Edible salt not only has the effect of sterilization, but also can wash away the insects in the cherries.

In mid-April, when the larvae of cherry fruit bees have not yet shed the fruit, the insect fruits should be removed in time and buried deeply, and at the early flowering stage of cherries, pyrethroid insecticides or organophosphorus insecticides can be sprayed.

10 cherries and 9 worms? Teach you how to clean cherries and easily remove insects from cherries.

Hello, Hubi's new orchard should be avoided as much as possible to be mixed with other fruit trees, and the mixed fruit trees should be strengthened for their main hosts; Eradicate overwintering pests. trap and kill overwintering larvae before fruiting; In early spring, before germination, scrape off the coarse and old warped skin, and burn them intensively, and cut off the damaged new shoots in time in May and June; Prompt medication. Generally, spraying is sprayed when the worm is still in the egg stage, and the drug is targeted according to different insect pests.

The whole garden is carefully sprayed with 5 Baumé stone sulfur mixture, which can effectively reduce the number of overwintering larvae. From budding to the bud dew red period, that is, when the overwintering nymphs crawl out of the wax shell and transfer, the pants are noisy, sprayed for control, and the agent refers to the mulberry white scale. Spraying should be done at the latest before the female shell hardens.

In the peak period of nymph hatching, combined with the prevention and control of other insect pests in mid to late May, spray 10% imidacloprid wettable powder 2000 3000 times, or 48% Lesben collapse 1500 times, or 40% quick-culling emulsifiable concentrate 1200 times, etc., spray once every 7 10 days, spray 2 times.

1. New orchards should be avoided as much as possible to be mixed with other fruit trees, and the main host of fruit trees that have been mixed should be strengthened;

2. Eliminate overwintering pests. trap and kill overwintering larvae before fruiting;

3. Scrape off the coarse and old warped skin before germination in early spring, and burn it intensively, and cut off the damaged new shoots in time in May and June;

4. Timely medication. Generally, spraying is sprayed when the worm is still in the egg stage, and the drug is targeted according to different insect pests.

1. Introduction to cherries.

Second, the type of pest.

3. Prevention and control methods.

In fact, for the heart-eating phenomenon that occurs in cherry trees, we can control it through various methods, so that the damage of these heart-eating insects to fruit trees can be minimized. Let me propose a few solutions for you, first of all, when we plant in the orchard, we avoid mixing other fruit trees with cherry trees, so as to reduce the heart-eating insects in other fruit trees to run to the cherry trees. Secondly, for the damaged treetops on the fruit trees, the fruit farmers should cut the trees in time.

Finally, if the occurrence of heartworms is more serious, it should be controlled by drugs**.

Pear heartworm, which is a very common pest, the damage to the trees is also relatively large, be sure to spray pesticides in time, try not to mix all kinds of plants. Be sure to pay attention to bagging and pay attention to the cleaning of the orchard.

If there is such a pest, then we can use professional pesticides, spray in advance, or sprinkle some quicklime solution, or use osthole, which can have a good effect.

Probably a green blind bug. When planting, you must choose fertile soil, and then during planting, you should also do a good job of weeds treatment, regular watering, regular fertilization, and spraying pesticides to prevent pests and diseases in advance. In this way, the invasion of these pests and diseases can be well controlled.
