How to get rid of black aphids on cherry tree


How to Get Rid of Black Aphids on Cherry Tree? (Complete Guide)

Cherry trees are grown for their fruits. Cherries are loved by almost everyone.

Black cherry aphids love them too. They infect cherry trees and devour the sap out of the tree.

They especially love the sweet cherries. Do you see these wretched pests on your cherry trees?

Signs of Black Cherry Aphids

These pests are easy to spot. Black Cherry Aphids are shiny, metallic black, and 0.3cm long.

They are bigger than most aphids. Mature black aphids may be winged or wingless.

If you see curled, distorted leaves and sticky, black ‘honeydew’ on fruits and leaves your tree is housing these pests.

What are the little black bugs on my cherry tree?

These are most probably Black cherry aphids. They love to hang out on cherry trees and suck the sap.

They are often seen in large numbers(colonies) on leaves.

Are black aphids harmful to plants?

Black aphids are a nightmare to cherry plantation owners.

Black aphid infestation can definitely harm growing cherry trees. Some trees may even die.

But they can not harm a well-established cherry tree. If the infestation is heavy then it may even harm fully-grown trees.

They cause honeydew deposits on leaves and branches.

At such points sooty mold, a fungus thrives and can be a cosmetic problem. If this mold spreads to fruits too, they won’t be edible.

Where do black aphids come from?

Adding too much fertilizer to the soil increases foliage growth and attracts these pests.

They hatch from their eggs shortly before bloom. These newly hatched aphids undergo many reproduction stages and can rapidly multiply.

Wingless females are hatched from the eggs and undergo asexual reproduction to produce more aphids.

In such reproduction, some winged aphids are produced.

These winged pests migrate to Mustard plants. When it’s time for them to lay eggs, they come back to the cherry trees.

Black Cherry Aphid eggs

Eggs of these pests are shiny black and oval in shape.

Black Cherry Aphids lay eggs on buds or bark. These eggs hatch just before bud break in the spring.

How do black aphids spread?

Adult Black Aphids usually spread from an affected plant to a healthy plant via ants.

Winged Aphids can fly. They go to Mustard plants and return to Cherry plants to lay eggs.

How do I get rid of black cherry aphids?

As these pests harm your fruits, it becomes crucial to get rid of them for good.

The best time to get rid of them is early spring, as they replicate rapidly at this time.

There are various ways to do it.

The most effective way to control these pests is to encourage their natural predators.

What eats Black Aphids?

Biological control of Black Cherry Aphids can be done by introducing Syrphid flies, Lacewing larvae, Parasitic wasps, and soldier beetles.

This method is completely safe for our plants and gets the job done.

Will ladybugs eat Black Aphids?

Ladybugs are the main predators of Black Aphids. If they are introduced on an infected plant, these pesky pests will be gone.

An adult ladybug will eat 50 or more aphids in a day!

The convergent lady beetle is specifically used to control the spread of aphids.

This type of beetle will not harm other types of insects.

Cutting the infected leaves

Whenever you see leaves with colonies of Black Aphids, cut the leaves off and drop them in a basket.

If you leave such leaves/branches on the ground, the aphids go back to the tree.

If you actively cut leaves with aphids on them, your cherry trees will be completely fine.

Tip: You can dislodge small colonies of aphids using a powerful stream of water.

Black Cherry Aphids vs. Neem Oil

If the Black Cherry Aphid infestation is heavy, it needs to be controlled by other means.

Many choose to spray chemical insecticides, but I wouldn’t advise this.

You can spray Neem oil on the affected branches. This solution is completely organic.

You can also spray horticultural oils on the affected leaves and branches.

Prior to treating the tree with these oils, water abundantly. A well-watered tree will not have side effects from horticulture oils.

Catch ’em early

If you could predict aphid infestations early, wouldn’t it be great?

It can be done.

Place sticky cards on branches of cherry trees in late winter. This helps you monitor the populations of aphids.

Check these sticky cards regularly. If you see tiny black aphids on them, spray it with Neem oil.

Insecticidal soap spray

I take care of these pests via biological control methods or other natural means. Some people choose to use Insecticidal soap.

Do not spray insecticidal soap when the temperature is warm or when the bees are active.

Spraying insecticidal soap in the evening is ideal.

Two or three such applications may be needed in case of stubborn infestations.

A Combination of Insecticide and Horticulture oil

Spray a combination of horticulture oil and insecticide chlorpyrifos on the trunk and branches of your cherry tree.

This solution can kill bees. So, it is ideal to do this in the evening when the bees aren’t around.

Preventing an infestation

As you already know prevention is better than cure. How do you prevent an aphid infestation?

  • Do not overfeed your plant. Some people tend to feed a lot of nitrogen fertilizer to their trees. This has proven to attract Black Cherry Aphids.
  • Deter ants. Ants move the aphids around. Control ants and you can control the spread of the Black Cherry Aphids. You can do so by making a 3-5″ barrier of tanglefoot on your cherry tree’s trunk. Do this every spring and you’ll no longer see aphids on your cherry tree. Make sure ants do not reach branches of the cherry tree and your tree will thrive just fine!

I hope this article will be helpful to you, happy gardening! 🙂

How to Kill Aphids in Cherry Trees Before Spring | Home Guides

By SF Gate Contributor Updated July 26, 2021

Aphids are trouble for a wide range of plants, and the cherry is not exempt from this pest. The most common aphid in cherries is the black cherry aphid (Myzus cerasi), a 1/8-inch-long, shiny black aphid that overwinters as eggs on the bark of smaller cherry branches, emerging in the spring about the time buds are opening. After three to four weeks, these young females begin giving live birth to more wingless females without the need for fertilization. Populations of cherry tree aphids, or black bugs on cherry trees, can quickly get out of hand – killing them before they hatch is the best form of control.

  1. 1. Water Your Tree

    Provide your tree with supplemental water at least a week prior to beginning to treat it for aphids. Water it until the soil is moist, but not so much that the tree is standing in water. A well-hydrated tree is less likely to be injured by horticultural oil treatments.

  2. 2. Treat Your Tree

    Spray horticultural oil on your cherry tree, making sure to coat the bark and branches thoroughly. Apply this treatment in the evening if bees are active near your cherry tree, since it can be toxic to these pollinators. Allow the spray to dry at least four hours before treating the tree further.

  3. 3. Monitor the Population

    Place yellow sticky cards on the branches and trunks of cherry trees in late winter, as buds begin to swell, to help monitor aphid populations. You can find these from integrated pest management dealers. Check the sticky cards regularly – if you see tiny black aphids (immature aphids are much smaller than adults), prepare to spray again before populations climb.

  4. 4. Use Insecticidal Soap

    Coat your cherry with insecticidal soap as soon as black cherry tree aphids are active, or wait until after the petals fall from the tree to apply imidacloprid to the soil around your tree. Repeat applications of insecticidal soap weekly until you don't see any more aphids on sticky cards if you choose this option.

  5. 5. Control Overwintering Aphids

    The Old Farmer's Almanac suggests that if you spray dormant horticultural oil, you will kill overwintering aphid eggs. That should give you a head start on aphid control in spring. Most aphids cause damage when temperatures are between 65 and 80 degrees.

  6. 6. Use Biological Controls

    One of the best ways to get rid of cherry tree aphids is to introduce biological controls, according to Washington State University Tree Fruit. Lady beetles, soldier beetles, predacious midges, lacewing larvae and syrphid flies are all good biological controls of aphid populations.

    Things You Will Need
    • Horticultural oil

    • Sticky cards

    • Insecticidal soap (optional)

    • Imidacloprid (optional)

    • Biological controls (lady beetles, lacewing larvae, etc.)

    Tip

    Aphids are often well controlled by beneficial insects once abnormally large populations are reduced in size. Refrain from applying broad-spectrum insecticides to allow these insects to help you with pest control. Cherry trees (Prunus spp.) are hardy in U.S. Department of Agriculture plant hardiness zones 2 through 8.

    Warning

    Watch for ants in your trees – if they discover an aphid population, they may protect these sap-sucking insects from natural predators by feeding on honeydew that the aphids secrete.

Every gardener had to deal with the fact that the trees in the garden are occupied by pests. For example, aphids on cherries are quite common. Consider the signs of its occurrence, control and prevention measures.

General information about the pest

Black aphids, which most often appear on cherries, are small, dark-colored insects averaging 2 mm in length. They feed, like other species of this pest, with juice, which is obtained from the tissues of young shoots, leaves and buds. Aphids especially love the tops of the shoots with the most tender leaves. Thus, insects weaken the plants, the leaves on them curl, do not develop, and if the pests managed to occupy the shoots before flowering, then the flower buds are also affected.

Aphids begin active activity on cherries in early spring, with the onset of the first warm weather. As soon as the buds begin to bloom, the pests reproduce quickly, they are able to give several generations in a season. If urgent measures are not taken, the crop can be seriously affected by aphids.

How to tell if an aphid has settled on a cherry tree

Finding pests on the leaves of trees is not difficult, you just have to look at them carefully. Aphids are more often located on the youngest leaves, mainly on their lower side, and if single specimens are not so clearly visible, then it is difficult to miss an already sufficiently multiplied colony.

A characteristic sign of plant damage by aphids is a sticky liquid that covers the leaves, which makes them shiny. The leaves are deformed and curled. Ants can be seen near the pests, which specially grow aphids because of their sugary secretions.

The danger and harm of aphids is not only in the weakening of plants, but also in the fact that it carries viral infections, and the sweet liquid serves as a breeding ground for soot fungus.

How to deal with aphids in the garden

Naturally, it is impossible to leave everything as it is, so as not to lose a significant part of the future harvest. The fight against aphids should be started immediately, as soon as it is detected. You can save a tree with the help of folk remedies, agricultural chemistry, or attracting natural enemies of the pest. Each of these methods has its own advantages and disadvantages. Which one would be more appropriate to apply depends on the desire and capabilities of the gardener.

Folk remedies

If there are still few aphids, it is better to try to get rid of them by using water, that is, simply wash them off with a stream of water. But this method is only suitable if the pests have not yet had time to multiply strongly.

In addition, you can fight with folk remedies. They are not as aggressive as commercially produced insecticides, and are not harmful to plants, do not poison them. But it should be borne in mind that folk remedies are not so effective - cherries will have to be processed not once per season, but several.

Soap and Ash

Cherry aphid killer recipes:

  • Soap solution. It will be necessary to dissolve shavings from ½ a piece of laundry soap (150 ml of liquid or 150 g of tar) in 10 liters of hot water. Spray the cherries with this solution.
  • Ash infusion. This tool is doubly useful: it not only destroys aphids, but also feeds cherries with mineral elements. Cooking it is simple: pour 0. 3-0.5 kg of ash into 5 liters of boiling water and leave to infuse in a sealed container for a day. Then add another 5 liters of water, add 50 g of any soap and use the infusion for spraying.

According to gardeners, these aphids are time-tested and show good results after the first application.

Herbal infusions

No less effective in the fight against aphids and plants with insecticidal properties, which can be found in any household.

Top 10 herbal infusions against aphids:

  1. Bow. Take 30 g of husk, pour 1 liter of boiling water, leave for 6 hours. Add a little laundry soap to the liquid for the product to stick to the leaves.
  2. Garlic. 200 g of crushed cloves insist 5 days in 1 liter of water in a sealed container. Before use, dilute 25 g of infusion in a bucket of water.
  3. Tobacco. 200 g of dry leaves insist in 5 liters of water for 2 days. Add another 5 liters of water.
  4. Chamomile. 100 g of inflorescences and herbs insist 12 hours in 1 liter of water. Working solution: dilute the infusion with water 1 to 3, add 5 g of soap for every 1 liter of the resulting liquid.
  5. Marigolds. Fill the bucket up to half with crushed plants (together with flowers), add water to the top, leave for 2 days, add 50 g of soap to the bucket before spraying.
  6. Hot pepper. 1 kg of fresh pepper in pods or 0.3 kg of dry insist in 10 liters throughout the day. Dilute with water 1 to 10.
  7. Pine. Infuse 1 kg of needles in 4 liters of water for a week. The concentration of the working solution is 1:1.
  8. Citrus. Pour 100 g of dry peels into 1 liter of hot water, leave for 3 days.
  9. Potatoes or tomatoes. Infuse 1 kg of fresh or 0.5 kg of dry leaves in a bucket of water for 6 hours.
  10. Celandine. 400 g of fresh grass or 100 g of dry, pour 1 liter of boiling water, leave for 1-1.5 days.

All infusions must be filtered before use so that the liquid is clear, without impurities and does not clog the sprayer, and then spray the plants.

Spray carefully to get the solution on both surfaces of leaves and shoots. Processing of cherries can be carried out during budding, after flowering, during the period before the berries ripen, but no later than 2 weeks before they are harvested.

Agrochemistry

Those who want to deal with black aphids "immediately and permanently", of course, will have to choose synthetic insecticides. They act quickly and as efficiently as possible, but you need to remember that you can use them only at the beginning of the season, but not when the berries are already ripe.

Insecticides may be used in the home garden:

  • Iskra;
  • "Fitoverm";
  • "Commander";
  • "Aktara";
  • Corado;
  • "Confidor";
  • Fufanon and others

It is recommended to spray cherries for prevention even before bud break - this will destroy the wintering aphids. And during the season it is better to alternate drugs so that the pest cannot get used to one of them.

The last treatment before picking berries must be carried out no later than the time indicated in the instructions for the drug as a waiting period!

Biological methods

Control measures for black aphids include planting crops and flowers with a strong smell near fruit trees:

  • coriander,
  • garlic,
  • fennel,
  • daisies,
  • lavender,
  • basilica,
  • marigolds,
  • mint,
  • mustard,
  • shit.

Their pungent or spicy smell should repel pests.

You can fight aphids by attracting birds that actively eat pests to the garden:

  • sparrows,
  • tits,
  • warblers,
  • wrens,
  • hemp,
  • kinglets,
  • robins.

Insects that are enemies of aphids can also be attracted:

  • hoverflies,
  • earwigs,
  • riders,
  • wasps,
  • predatory bugs,
  • ground beetles,
  • ladybugs.

Plant daisies for hoverflies, amaranth for ground beetles, ferns for lacewings, and earwigs in wood shavings. Naturally, if such a control option is chosen, it is impossible to use pesticides so as not to poison the birds and beneficial insects.

Aphid control

So that the cherry aphid does not breed in the garden and it is not necessary to figure out how to deal with it, some preventive measures must be taken. For example, a pest likes to hide in weeds, it can live on viburnum, linden and bird cherry, so you need to regularly weed out weeds, shoots, remove their remains in the fall, then whiten tree trunks to prevent aphids harmful insects from getting wintering. Anthills should be destroyed, preventing ants from taking care of aphids and spreading them to new plants.

The pest is more likely to settle on plants overfed with fertilizers, so it is important to adhere to the norms during top dressing, not to add more mineral elements to the soil than necessary. The same applies to cherries weakened from nutritional deficiency, they are also chosen by pests. In this case, you will need to feed the plants in the garden with fertilizers.

Aphids on cherries can appear at any time of the season. To combat it, you can use any method you like or alternate them.

    • 3.1 - the appearance of aphids on plants. If you miss the moment and allow these insects to multiply, you will not have to wait for the harvest. With garden crops, things are a little easier, since a short-growing plant can be completely watered with insecticide. If an aphid started up on a tree, it is unlikely that it will be possible to get rid of it completely. For example, it is possible to process a whole cherry from aphids only from some kind of lifting mechanism. This is a tall tree and parasites will almost certainly remain on the upper branches.

      Why aphid appeared on the cherry

      In general, the answer is obvious: he wants to eat. The food of this large superfamily of Aphids is plant sap. In nature, there are 5000 species of aphids, and all of them parasitize vegetation. If all these insects could feed on the juice of any plants, there would be no flora left on Earth. Fortunately, aphid species are relatively specialized. Stone fruit trees are most commonly parasitized by Myzus Cerasi or the cherry aphid.

      Much more interesting is the question “how aphids appear on cherries”. After all, if you consider these insects, it turns out that they are wingless.

      There are three ways for pests to appear on trees:

      • insects have hatched from eggs left on the branches of cherry trees or other crops since autumn;
      • ants brought their "cattle" to "graze";
      • arrived.

      There are very few winged individuals on plants, as they are fertilized females. They can no longer stay on the old tree, they must expand their habitat. After fertilization, the female simply flies away to another plant.

      Winged females in the colony are not numerous, they quickly fly away to a new place

      What aphids look like

      These are small insects, usually 2-3 mm in size. Although in the superfamily there are species whose representatives grow up to 7 mm. The mouth apparatus of these insects is of a piercing type. They pierce the surface of leaves or young shoots with them and drink the juice.

      The length of the proboscis of aphids is different. In some species, the mouth apparatus can reach very large sizes. This is due to the feeding habits of insects.

      In all types of aphids, there are wingless and winged forms. The first can also reproduce, but it ensures the reproduction of the population on the original host plant. Wingless females are unfertilized and reproduce by parthenogenesis.

      After fertilization, the female grows wings and flies away. This is how host plants change. On cherries, Myzus cerasi or cherry aphid most often appears.

      Description

      A sexually mature, unfertilized female cherry aphid has a pear-shaped, wide body. The head is at the narrow end of the body. The length of a wingless adult is 2-2. 4 mm. The color is black on top and brown on the side of the abdomen. In immature individuals, the color of the back is dark brown. The body of the cherry aphid is shiny.

      Dark green antennae divided into 6 segments, about 1 mm in total length. Antennae grow from wide frontal tubercles that form a groove.

      The fertilized winged specimen is brilliant black. The length of her body is 2.4 mm. The flying female lays oval black eggs.

      The coloration may seem to reveal black aphids on green cherry leaves. This is the case. But this color hides insects well on the dark bark of cherry branches. The same applies to insect eggs.

      The most common form of aphids: viviparous unfertilized female

      The area of ​​distribution of these insects excludes only those regions where their main food crops are not grown:

      • South America;
      • Antarctica;
      • South and Central Africa;
      • Southeast Asia.

      Cherry aphids cause the greatest harm in the southern regions of the former USSR, which stretch along a line from Moldova to Central Asia.

      Feed base

      Black aphid is an oligophage and eats not only cherries. Her diet also includes other stone fruit horticultural crops:

      • sweet cherry;
      • drain;
      • apricot;
      • peach.

      Black aphid prefers sweet cherry as a relative of cherry. But he will not refuse other fruit plants either.

      In addition to cultivated trees, the cherry aphid feeds on:

      • soft bedstraw;
      • eyebright straight;
      • clinging bedstraw;
      • Veronica officinalis;
      • spring gear.

      The presence of aphids on wild plants would be of little concern if the species did not have flying females. If there is any of the listed herbs in the vicinity of the garden, affected by aphids, there is no doubt: insects will soon appear on garden trees.

      Pest life cycle

      The black aphid life cycle begins in early spring, when the first generation of insects emerge from overwintered eggs. Eggs hibernate at the ends of annual shoots near the buds. And the first larvae appear simultaneously with bud break. Aphids feed on the juice of young leaves, which is why the latter turn black and dry. During the season, several generations of pests change on the tree.

      Since the birth of already living small copies of adults occurs during parthenogenesis, 14 generations can be born during the warm season.

      Light and small individuals - young aphids

      Signs and causes of the appearance of aphids on cherry leaves

      By daily inspection of young cherry shoots, it may be possible to notice the appearance of pests even at an early stage. But usually gardeners find aphids when they are already comfortably nestled on a tree:

      • this year's shoots are strewn with black insects;
      • whole colonies of insects are found on the back of the leaves;
      • leaves curl and turn black;
      • the flowers are starting to fall off.

      The first appearance of aphids is possible even in early spring, when flower buds are just beginning to bloom on cherries. These are the pests that came out of the overwintered eggs. The second wave will be after the females of the first generation grow up and are fertilized. Around the same time, ants can bring insects to the trees. They also want sweets. Excrement excreted by aphids contains a lot of sugar. Further, pests can appear at any time. It all depends on how quickly the winged female reaches the tree.

      Measures against aphids on sour cherries

      Treat cherries for aphids for the first time in early spring. But not when tree trunks are usually whitewashed, getting rid of overwintered bugs, but a little later: at the time of bud break. At an earlier time, only those drugs that act on pest eggs can be used. These are usually strong chemical insecticides. It is possible in early spring. Later, before processing cherries from aphids, you need to pay attention to the degree of ripening of the berries.

      How to get rid of aphids on cherries folk remedies

      Most chemical insecticides have a long duration of action. Many of them are systemic, that is, they can penetrate into plant tissues. Trying to drink the juice, the aphid absorbs the poison at the same time. This is almost ideal if you spray cherries from aphids with such insecticides in early spring, when sap flow begins.

      But it is undesirable to use such preparations during the ripening of the crop, although the manufacturer assures consumers of the safety of modern insecticides. At the stage of half-ripe berries, aphids on cherries are best treated with folk remedies:

      • ammonia;
      • tar soap;
      • ash;
      • soda ash;
      • decoctions of aromatic herbs.

      The practice of gardeners shows that the best option is soda ash. But other recipes have a right to exist. The dosage in all recipes is calculated on a bucket of water.

      Attention! Particular attention should be paid to the underside of the leaves.

      Aphids cluster closer to the central vein on the leaf

      Ammonia

      Grate half a bar of laundry soap and dissolve in hot water. The resulting soapy solution is poured into a bucket of water and a 100-ml bottle of 10% ammonia is added there.

      It is necessary to treat black aphids that have settled on cherries twice with a break of a week. Pay special attention to the underside of the leaves.

      Tar soap

      If it is not available, you can use ordinary household soap. Tar is more effective because of the smell. Otherwise, there is no difference between detergents. The recipe is the same as with ammonia, but without the latter.

      Herbal decoctions

      These agents do not kill aphids, they only repel them. Therefore, the effectiveness of decoctions and infusions of herbs is very low. But if you need to do something urgently, and only herbs are at hand, you can use this method. For decoctions use:

      • St. John's wort;
      • tansy;
      • wormwood;
      • calendula;
      • yarrow;
      • dandelion leaves;
      • tobacco.

      A stronger and at least slightly poisonous remedy: an infusion of potato or tomato leaves. It can also be made from fresh dandelion leaves or tobacco. For infusion, take equal parts of greens and water. Fresh chopped greens are poured with water and left to infuse for a day so that the plants secrete poisonous juice into the water. Then the infusion is filtered and sprinkled with cherries.

      Ash infusion

      Pour 0.5 kg of ordinary wood ash into a bucket of water and infuse for 3 days. Don't forget to strain before spraying the trees.

      Garlic infusion

      Crush the head of garlic and add a liter of water. Insist 5 days. Use diluted: 50 g of infusion in a bucket of water. 2 hours will definitely work.

      Garlic can be found in any home

      Dry mustard

      Mix 100 g of mustard powder in a bucket of water. Spray the cherries with the resulting mixture. For better adhesion of mustard to the leaves, soap can be added to the solution.

      Milk with iodine

      You will need a vial of iodine and half a glass of milk. The ingredients are diluted in a liter of water and the plants are sprayed with the resulting solution from aphids. Given the size of the cherry tree, the mortar will take a lot.

      Soda Ash

      It is sold in housekeeping departments as a substitute for dishwashing detergents. Experienced gardeners believe that using a soda ash solution is the best way to rid cherries of aphids during ripening. Since soda is used to wash dishes, it can even be used on already ripe cherries. The method of preparation is also simple: soda is diluted in water. Each gardener has their own proportions. Some use 3 tbsp. l. to a bucket of water. Others believe that you can’t spoil porridge with butter, and add the same 3 tbsp. l. per liter of water.

      All these traditional methods allow you to get rid of aphids on cherries in the summer when the crop is ripening. Until stronger drugs can be used. Plus, folk remedies are safe for human health.

      Biological treatment of cherries against aphids

      Biological preparations do not immediately kill aphids on trees, as happens when spraying with chemical insecticides. But their plus is that they are harmless to humans and they can be used even a few days before harvest. Minus: biological products are easily washed away by rain. But after the rain, you definitely don’t have to worry about the presence of an insecticide. Biologics include:

      1. Fitoverm: treatment of aphids 10-12 hours after application.
      2. Entobacterin: the effect is similar to Fitoverm. Can be applied 5 days before harvest. The best result is shown at an air temperature of 28-30 ° C, that is, it is best to spray the trees in the height of summer. At lower temperatures it is necessary to increase the concentration of the insecticide.
      3. An arrow with the active ingredient bitoxibacillin is harmless to warm-blooded animals. The insecticide starts working 2 days after spraying;
      4. The drug 30-plus is called just that. Its active ingredient is an emulsion of vaseline oil, which covers the aphids of the spiracle. The advantage of this insecticide is that it is not washed off by rain. In addition, vaseline oil is completely non-toxic. It can be applied at any time. Minus: the emulsion will not reach the aphids inside the rolled sheet.

      Biological preparations are a good and reliable alternative to folk methods of aphid extermination.

      You can also attract predatory aphids to your garden

      How to deal with chemical aphids on cherries

      All chemical insecticides can be applied no earlier than 20 days before harvest. The drugs give the best effect in the early stages of the growing season. To almost completely get rid of black aphids on cherries, the first spraying should be done at the beginning of sap flow. And it is necessary to use systemic preparations that can penetrate into plant tissues. The larvae that emerge from the eggs will die either by direct contact with the insecticide, or by trying to drink the juice.

      Of the chemicals used:

      • imidacloprid: class of neonicotinoids, enteric-contact action, systemic;
      • karbofos/malathion: reliable insecticide against aphids, but very toxic to humans, non-systemic;
      • thiamethoxam: neonicotinoid class, enteric-contact action, systemic;
      • alpha-cypermethrin: pyrethroid class, enteric contact, valid up to 2 weeks if not rained;
      • beta-cypermethrin: pyrethroid class, enteric contact;
      • deltamethrin: pyrethroid class, enteric contact.

      These insecticides are unlikely to be sold under their real names. Usually these are active ingredients in the composition of registered trademarks. Imidacloprid is sold under the names: Biotlin, Confidor Extra, Tanrek.

      Karbofos can be found under the brands: Prophylactin, Aliot.

      Thiamethoxam is one of the most favorite preparations by gardeners: Aktara, Voliam Flexia, Engio Forte.

      Trademarks for other insecticides are not very diverse. Alpha-cypermethrin - Neophral, ​​beta-cypermethrin - Kinmiks, deltamethrin - Decis Profi.

      How to mechanically remove aphids from cherries

      Mechanical methods for removing aphids from cherries include:

      • breaking off infected shoots;
      • washing off aphids from the crown of a tree with a strong water jet;
      • use of ant belts.

      It is impossible to completely remove aphids from cherries in this way. You can only reduce its concentration on one plant. Anti-ant belts will not allow ants to bring their "cows" to the trees, but they will not protect against flying aphids.

      In addition, this belt will not help against aphids on felt cherries. Today this plant belongs to the genus of plums, but it is a shrub 1.5-2 m high. Sometimes the felt cherry grows up to 3 m. It is also suitable for spraying.

      Pests will have to be knocked down from tall cherry trees with a jet of water. But along with insects, the whole crop falls on the ground. However, with a high degree of probability, it will just be possible not to worry about it. All the same, it will not ripen, since the aphid will drink all the juice necessary for normal fruiting. Well, if you can save the tree itself.

      Twisted leaves are best cut off immediately

      Comprehensive measures

      It is better to get rid of aphids by applying a complex of measures at once. To prevent the ants from bringing their "cattle" to the branches, you need to put trapping belts on the cherry trunks and regularly update the adhesive surface. Branches in spring and leaves in summer should be regularly sprayed with insecticides or insect repellents. It will not be superfluous to weed weeds, which also serve as a food base for aphids. It is necessary to remove already dying, twisted leaves manually, as insects hide there.

      How to properly treat cherries from aphids

      To properly treat cherries, you need to follow some rules. This includes not only the choice of the drug depending on the season, but also checking the weather forecast, and observing safety precautions.

      When can cherries be treated against aphids? Oil-based insecticides are chosen to prevent larvae from hatching from eggs. Such preparations are poorly washed off with water and can last for a long time until the snow melts and frosts with frost are possible.

      Chemical insecticides can also be applied during the cherry blossom season. At this time, it is better to use long-acting systemic drugs.

      After the berries appear, chemical insecticides can be used while the cherries are still green. After the reddening of the fruit, it is more advisable to switch to biological products, and shortly before harvesting, use folk remedies. The latter will have to be applied weekly until the crop is harvested.

      After picking cherries, closer to autumn, you can switch back to systemic insecticides. Late autumn to apply something like this does not make sense. It is only necessary to clear the trees of pieces of old bark and carry out the usual autumn procedures.

      Personal protective measures

      When processing cherries with folk remedies, protection is not particularly required, since all these substances are in the kitchen of any housewife. But when spraying trees with chemical insecticides, especially karbofos, protection is already necessary. Today, it is not difficult to buy a full chemical protection suit.

      Attention! Work with karbofos should be carried out only in such clothes.

      Other insecticides do not require such strong protection, but the minimum necessary: ​​a respiratory mask, goggles and gloves. However, cypermethrins are moderately toxic to mammals.

      This “dress” is acceptable when spraying cherries with folk remedies, but is completely unsuitable when working with industrial insecticides

      Processing rules

      Cherries should be processed in dry weather, after checking the weather forecast. It is necessary that there is no rain for the next 3 days. Otherwise, insecticides will be washed away with water. Time of day for processing: early morning or evening. At this time, flying aphids can no longer rise into the air and will also fall under the action of the insecticide.

      Dosage of commercial preparations is indicated on the packaging. Depending on the type of insecticide, both the dosage and the frequency of treatment may vary. Folk remedies do not have strict dosage norms, and the frequency is at least once a week.

      Preventive measures

      It is impossible to permanently get rid of aphids in the garden. Also, you can not destroy it using only one way to fight. A set of measures is needed to radically reduce the number of aphids in the garden:
