16 PROVEN Ways to Get Rid of Aphids on Cherry Tree (2022)

How do you get rid of Aphids on Cherry Tree?

Getting rid of Aphids on Cherry Tree wasn’t as easy as I thought. Natural remedies only worked temporarily, commercial products didn’t live up to expectations, and there isn’t enough information on the internet.

That’s why I created a list of 16 PROVEN Ways to Get Rid of Aphids on Cherry Tree.

This ultimate guide is broken down by how to get rid of aphids on cherry tree and how to prevent aphids with natural remedies that work, commercial products that live up to expectations, and secrets that only experts know!


What Does Aphid Damage Look Like?

Aphid Damage can be quickly and effectively-identified. You should look for the following:

  • Misshaped, curled, or yellow cherry tree leaves
  • Sticky substance on the cherry tree stem
  • Cherry Tree that are growing deformed
  • Galls on the roots or leaves
  • Small bugs on the opposite part of the leaf
  • Large amounts of small bugs on the stem of the plant.
  • Small bugs on the root of the plant

10 PROVEN Tips to Get Rid of Aphids on Cherry Tree

#1.

Manually Remove Aphids

If there are less than a dozen aphids…

  • Use a dry paper towel, pick the aphids off the individual cherry tree leaves, and gently crush them.
  • Dispose of the dead aphids in a garbage bag. Leaving potentially alive aphids behind will just cause a re-infestation.
  • After removing the aphids you should inspect your leaf or cherry tree to ensure there are no more aphids.
  • Use a wet paper towel to rub any sap or residue from your leaf or cherry tree to prevent additional aphids or even ants from attacking your plant.

If there are more than a dozen aphids…
  • Use a wet paper towel to gently brush the aphids off the cherry tree leaves and into a garbage can.
  • Because some aphids have wings and others can crawl at a relatively fast speed you should never brush them into the grass. This can cause re-infestation or infestation of other cherry tree.
  • After removing the aphids, you should again inspect your leaves and cherry tree to ensure there are no more aphids
  • Use another wet paper towel to rub any sap or residue from your leaf or cherry tree to prevent additional aphids or harmful insects like ants from attacking your plant.

#2.

Spray the Infected Cherry Tree Leaves with a Hose

If Aphids are on your entire leaves…
  • Spray the underside of your cherry tree leaves in the morning with the high power setting on your hose until the aphids are removed. Low power settings or a watering won’t properly remove aphids.
  • Then let your leaves completely dry.
  • Spray the underside of your leaves and your plant in the evening again until the aphids are removed.
  • To be safe, it is recommended to repeat the steps every day until aphids are completely gone.
  • It is also recommended to follow the same steps with healthy cherry tree immediately surrounding your attacked plant to help prevent the spread of aphids.

#3.

Use Insecticidal Soap

If there are large amounts of aphids on your cherry tree…

  • Use an traditional choice for controlling Aphids, such as Insecticidal Soap.
  • Insecticidal Soap is a low-toxicity pesticide made of potassium and fatty acids that have been used by gardeners and farmers for centuries. It can kill large amounts of soft-shell insects like aphids without harming your plants, animals, or humans.
  • You can also make your own Insecticidal Soap by combining one cup of oil (peanut, vegetable, corn, etc.) with one tablespoon of dish soap. Do not use bleach.

#4.

Use Commerical Pesticides

If Aphids just won’t die then…
  • Spray your cherry tree with a systemic pesticide that contains the chemical, Imidacloprid early in the morning. This is a commercial chemical that is non-toxic to humans and beneficial pollinators, but deadly to harmful insects like aphids.
  • Repeat applying your pesticide until aphids are dead. It should be noted that it can take up to two weeks to fully kill an infestation of aphids and prevent them from spreading.

#5.

Apply an Organic Pesticide

If you Want to Get Rid of Aphids Organically…
  • Then create your own organic pesticide. You can create it by doing either of the following:
    • Mix 3 teaspoons of dish soap with 1 quart of water. You can either spray or gently apply this solution onto your cherry tree leaves
    • Mix 1 teaspoon of dish soap, 1 teaspoon of cayenne pepper, and 1 quart of water.

Like a commercial pesticide, you should apply this solution to your cherry tree in the morning until the aphid infestation is gone. Again, it may take two weeks to kill your infestation and it is not as effective as chemical pesticides.

It should be noted that while organic pesticides are almost guaranteed safe to you, children, and animals, it is typically not as effective as commercial products.

Do Not Use…
  • Coffee Grounds, Banana peels, or any other home remedy that you may read about.

While you may read about these remedies in other articles there is little scientific evidence that they are effective and can even attract other insects or garden pests.


#6.

Try Essential Oils

If Organic Pesticide doesn’t work then…

  • Use essential oils to get rid of aphids.
    • Use 4 to 5 drops of peppermint, clove, rosemary, and thyme and mix it with 1 cup of water. Spray onto the cherry tree with aphids in the morning. You can also apply in the evening too.
    • Repeat until the aphids are gone.

Essential oils are not only a great way to get rid of aphids, but also is an effective way to get rid of mosquitoes and other insect pests.

It should be noted that Essential Oils are a great way to Prevent Aphids and should be applied as soon as you grow new cherry tree.


#7.

Dust Your Cherry Tree Leaves

If You Don’t Want to Spray Aphids then…
  • Apply a light dusting of diatomaceous earth. While not toxic to humans or animals, it can immediately kill aphids with it’s razor sharp particles.

This type of dusting should be used as a last result. It is more expensive than other remedies and can potentially kill beneficial insects and bees that visit your cherry tree.

Dusting is also a great way to prevent aphids. Simply, apply light dusting on your leaves in early summer to prevent harmful insects like aphids from attacking your cherry tree.


#8.

Cut Back the Cherry Tree

If Aphids have spread to the entire cherry tree…

  • Remove entire leaves or branches of the cherry tree if manually removing aphids, spraying your playing, or applying insecticides don’t work.
  • It recommended to first remove leaves. Wait a day. If aphids are still on your cherry tree then remove a few branches. Never remove more than one-third of the branches on your plant or it will die.
  • Dispose of your infected leaves or branches in the garbage. Do not leave them near other plants where the aphids can spread and do not compost them.

#9.

Attract Beneficial Insects

If you don’t want to use spray…

  • Then grow cherry tree that will attract ladybugs, hummingbirds, and green lacewings.
    • These bugs and birds are the best at most effectively and quickly eating and getting rid of aphids.

Ladybugs and Lacewings are the best type of insects to eat and destroy aphid eggs and larvae.

Birds like chickadees are the best animal to attract to eat and destroy large numbers of adult aphids.

Not only are beneficial insects great to help get rid of aphids, but they are essential in preventing aphids infestations.

Ladybugs, lacewings, and chickadees are also great creatures to attract to keep ant colonies away from your plants. Ants are known to be attracted to aphids and also protect them.

  • Some of the best plants to grow that will attract these aphid predators include:
    • Mint, Cherry Tree, Dill, Yarrow, Dandelions, Coneflowers, and Daisies.

#10.

Stop Growing Certain Other Plants

If none of the above steps work then…

  • Stop Growing the Plants around Cherry Tree that are attracting Aphids. This will help get rid of aphids and also prevent them.

These plants tend to have large leaves with shade where aphids can feast. Some of these plants are:

  • Potatoes
  • Soybean
  • Asparagus
  • Green Beans
  • Corn
  • Eggplant
  • Lettuce
  • Peppers
  • Rose
  • Sweet Potato
  • Brussel Sprouts
  • Cauliflower
  • Broccoli

If you really want to keep growing these plants then it is recommended you move them to a different part of your yard to reduce the spread of aphids to cherry tree.


11.

Apply Neem Oil

The Most Effective Way to Prevent Aphids is to…

Apply Neem Oil

  • While you can make your own organic neem oil it is recommended to mix commercialal Neem Oil with water in a garden sprayer and apply it onto all your fruit and vegetable trees in mid to late winter immediately before the last frost.

*Commercial neem oil is as safe as diy neem oil*

Find your last frost date HERE.

You will need to spray your cherry tree several times before the spring to destroy aphid eggs and repel mature aphids. Neem Oil will not kill beneficial insects with hard shells and bees.


12.

Pick the Right Neighboring (Companion) Plants

If you want to increase the likelihood of preventing aphids from attacking your cherry tree then you should plant the following (around plants that get attacked) that have strong scents that insects hate:

  • Oregano
  • Chives
  • Garlic
  • Onions
  • Leeks
  • Sage
  • Basil

These are also great plants to deter other garden pests like deer, squirrels, and chipmunks.

You can also grow plants that attract aphids to a different part of your garden or yard to prevent infestation to your good plants. These include:

  • Zinnias
  • Dahlias
  • Cosmos
  • Asters
  • Calendula
  • Nasturtium
  • Mum
  • Hollyhock

If you urban garden or have a very small space for these plants then it is recommended to use gardening pots for these plants to help save space.


13.

Avoid Overfertilizing

Fertilizing promotes new growth, faster.

Aphids are attracted to new cherry tree growth almost 100% of the time.

Instead of fertilizing your cherry tree all at once, you should apply smaller amounts of fertilizer throughout the year. You can also apply fertilizer once with a slow-release solution.

14.

Keep Cherry Tree Watered

Keep your cherry tree well-watered throughout the year.

This is especially important during hot summer days or droughts.

When cherry tree aren’t watered they become weakened, which decreases their chances of producing chemicals that can help them fend off harmful pests like Aphids.

If you notice that aphids continually come back to your plants every year then it is recommended to water at least one more day a week.


15.

Use Silver Reflective Mulch

Based on scientific studies at farms and gardens across the world, it has been proven that silver reflective mulch, also known as mylar, is effective at repelling aphids.

All you need to do is lay the mulch throughout your garden, grow your cherry tree in the mulch hole, and expect no aphids or dangerous insects.

Not only that, but mulch is a great way to prevent weeds and help your cherry tree retain valuable water and nutrients they need to grow vegetables.


16.

Destroy Ant Colonies

When you find aphids around your cherry tree you’ll also usually find ant colonies.

Ants can be found around aphids because they eat the waste aphids produce called “honeydew”.

Ants then protect aphids against beneficial insects like ladybugs and this can cause infestations to get larger, quicker.

Destroy ant colonies anywhere in your yard and around your cherry tree with one of the pesticides listed above.

And don’t forget to wipe off the cherry tree that had aphids on it. Even after ants and aphids are dead, leftover honeydew can attract other ants.


Conclusion

As a reminder, there are 16 Proven & Effective Ways to Get Rid of Aphids on Cherry Tree. They are:

  • Manually Remove Aphids
  • Spray Leaves or the Cherry Tree that have Aphids
  • Use Insecticidal Soap
  • Use Commercial Pesticide

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! 🙂

Aphids on cherries

It is very easy to notice the appearance of this pest on trees - the leaves (especially at the ends of branches) begin to curl and dry up. If measures are not taken to combat aphids, then young trees may die, and adults may lose a significant part of the crop.

If you unfold the cherry leaf, you can see black and yellow small insects - this is the aphid. Most likely, along with it, you will also see a cluster of ants on the tree, as they feed on aphid secretions. If aphids are found, take immediate action.

How to get rid of aphids on cherries

The fight against aphids is either folk remedies or special preparations. What is better?

Folk remedies get rid of aphids for a short time, basically they simply reduce the number of the pest. Therefore, you will have to process cherries several times per season, and this is quite dreary. But it is safe for health. This is on the one hand.

On the other hand, it is much easier to get rid of aphids with drugs, since usually one treatment is enough. And if you follow the instructions for use, without violating the waiting time, it seems like it’s not so dangerous. But if aphids appeared when the tree had already blossomed or fruits had formed, then chemistry can no longer be used, since firstly you can poison the bees; secondly, yourself. At the chem. aphid preparations usually have a long waiting period, that is, by the time the cherry ripens, the active substances of the insecticide may not yet decompose into safe substances.

How to treat cherries from aphids

Folk remedies are all kinds of herbal infusions that repel aphids, or environmentally friendly products that help to destroy aphids. Let's consider some of them.

  • Soap solution and ash . You can destroy the aphids on the cherry (or at least reduce the number of the pest and protect it from new settlers for a while) with a soapy solution with the addition of ash. Dissolve a piece of laundry soap in a bucket of water and add a glass of wood ash to the solution. Grate soap for better dissolution. Wet the whole tree liberally with this solution, and the leaves should be sprayed on both sides. If there is no ash, then you can treat the cherry only with soap.
  • Garlic solution . Often, garlic infusion is used to kill aphids, prepared either from the arrows of garlic, or directly from the heads. Pass the garlic through the prss or grate it and cover with plain water. Usually it is 200 g of garlic per 1 liter of water. Insist for 3-5 days. Then strain and add 40-50 ml of this infusion when spraying on a bucket of water. The aphids cannot stand the garlic "spirit", so they quickly retreat to another place. Hose water . You can also knock aphids off cherries with water under good pressure.
  • Milk and iodine . Spraying cherries from aphids can be done with milk and iodine. Take a vial of iodine, 100 g of milk and 1 liter of water. Mix everything, then pour into a sprayer and spray the tree. Along the way, spray berry bushes, they will also come in handy, since aphids especially like to settle on red and black currants.
  • Coca Cola . Surprising to many, but the fact is that Coca Cola helps get rid of aphids. And the thing is that this drink contains phosphoric acid, which kills the pest. Dilute cola 1:1 with water and spray aphid-infested trees and plants.
  • Baking soda . The easiest way to control aphids is to spray cherries with baking soda. 80-100 g of baking soda is dissolved in 10 liters of water and trees are treated with this solution. The method is good because it is possible to spray trees and plants at any stage of development.
  • Dry mustard . Dissolve 100 g of mustard powder in 10 liters of water. Neither aphids nor ants can stand the smell of mustard, so with one remedy you will repel both. For better sticking to the leaves, add a little liquid soap to the solution.

Preparations for fighting aphids on cherries

  • Fitoverm . I would advise you to first try to get rid of aphids with this biological preparation. Usually treatment with Fitoverm gives good results. To prepare a working solution, dilute 1 ampoule (5 ml) per 600 ml of water. Usually, aphid spraying is carried out as soon as the pest is noticed, usually before flowering. The second time you should spray the cherry after flowering, but no later than 5 days before harvesting. It is optimal when up to 20 days pass between treatments. Do not process cherries during flowering.
  • Aktara . This drug when the number of aphids on a tree is very large, in this case folk remedies will not help you. Spraying with Actara is carried out only before flowering, as it has a long waiting period. You can eat fruits only 60 days after the treatment.
  • Confidor . In the fight against aphids, the drug Konfidor has proven itself well. It kills aphids, but it also stimulates leaf growth. Confidor is also suitable for the southern regions, since even heat does not weaken its protective effect. You need to process cherries with these drugs only 1 time per season. 2 g Confidor per 10 liters of water if there are few aphids, if the pest numbers are high, dilute a double dose. Use the solution on the same day, as it is not subject to storage. For better adhesion of the solution to the leaves, add liquid soap to it.
  • Insecticides Spark , Decis , Intavir , Karate , etc. will also help against aphids on cherries. Use these drugs strictly according to the instructions, be sure to observe the waiting period.

  • One of the main pests of gardeners is 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 damage 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

    With a daily inspection of young cherry shoots, it may be possible to notice the appearance of pests even at an early stage. But usually gardeners detect 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 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 with 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 get rid of aphids in the garden forever. Also, you can not destroy it using only one way to fight. To radically reduce the number of aphids in the garden, a set of measures is needed:
