Aphids (aphids) - the most common pests of garden crops. The fight against aphids on fruit trees is a whole complex of agrotechnical measures, which include the observance of the rules of farming, the prevention and destruction of insect colonies.

Control over the number of pests is an important task for all gardeners and it must be carried out systematically and correctly.

Harmful aphids in fruit trees in summer

Many species of aphids superfamily pose a threat to fruit crops. Massive spread of the pest initially contributes to the small size of the insect up to 7 mm and often gardeners notice the defeat of the tree only after an increase in the colony.

A characteristic of aphids is the ability to migrate. Winged individuals can travel long distances in search of a more comfortable place. The main reasons for migration are overpopulation or deterring factors (treatment with pesticides).

And they take it from plants, mainly from young buds and leaves, piercing the tissues of trees with a thin proboscis.

Stable exhaustion of amino acids and microelements from the tree leads to its depletion. At the places of numerous punctures, development processes stop. Outwardly, this can be seen by the signs:

  • twisting and darkening the tops of the leaves,
  • premature loss of green mass,
  • deformation of shoots
  • painful growths on the trunk,
  • darkening, stopping the development and dropping of the buds.

A major threat to the fruit tree is the waste products of aphids. Excess moisture and carbohydrates are eliminated from the body by a pest in the form of sugary secretions, which are called padya or honeydew.

In leafy plates and stems covered with sticky liquid, photosynthesis and plant respiration are disturbed. It creates a favorable environment for the development of fungi, the spores of which are easily carried by the wind and can cause an epidemic in the garden plot. In addition, the aphid is a carrier of viral diseases that provoke an abnormal development of trees.

The defeat of the fruit tree pest leads to loss of quality and quantity of the crop, not the correct development and pain in the future. There are frequent cases of death or long-term recovery of fruit trees as a result of large colonies of aphids.

Maintenance work

It is possible to avoid exhausting pest control and preserve the health of fruit trees by minimizing the possibility of aphids appearing at the site in advance. For this, it is necessary to create uncomfortable habitat conditions for insects, to make the garden plot unattractive for the settlement of aphids.

  • Beneficial insects. Biological enemies of aphids: ladybugs, ground beetles, wasps and hoverflies. On the garden plot they can be attracted by planting daisies, carrots, dill, calendula, parsley.
  • Repellents. Plants containing phytoncides deter aphid with their specific odor. You can plant nearby fruit trees marigold, basil, lavender, mint, coriander.
  • Neighboring plants. It is important to avoid proximity to plants whose smell attracts the pest. These are: linden, viburnum, bird cherry, legumes. Ornamental plants: petunia, cleoma, mallow, nasturtium, poppy. Many gardeners plant these plants at a distance from fruit trees, and in the autumn destroy the affected crops. This distracts aphids from the plant being protected.

Having flown to a new place, the pest lays eggs that are capable of hibernation in the bark, under mulch, in the soil, in the rhizomes of the plant and dies. In the spring, with the advent of the first heat, new individuals hatch from eggs and begin to feed on young greens.

It is necessary to remove the entire peeled bark of the trees, change the layer of mulch, dig up the trunk circle, cover up the cracks and whiten the trunk. So for the pest eggs there is practically no possibility to transfer the winter.

If preventive work is absent or a particularly favorable season is created for the development of large aphid colonies, destruction of fruit trees is difficult to avoid. In this case, it is important to prevent an increase in the number of pests and minimize damage to the fruit tree.

Fighting aphids without chemicals

Chemicals are very effective, but they have a lot of side effects for human and pet health. Therefore, many gardeners use them only as a last resort, with massive lesions of the garden plot. An alternative replacement is to get rid of aphids at the sink with solutions from natural components that are environmentally friendly.

Treating trees to combat aphids

Ash-soap solution

The composition of the two components in the complex is the strongest aphid toxin.

Preparation of the solution:

  • ash (400 g) sift and pour water (5 l),
  • boil for 30 minutes
  • filter the solution and bring to a volume of 10 liters,
  • add 50 g of soap.

Additionally, this composition has protective and nutritional properties.

Birch tar

It is a dark, oily liquid whose odor repels aphids. Additionally, it is useful for the plant antiseptic and antimicrobial properties.

The composition of the solution:

  • tar 10 ml
  • laundry soap 50g
  • water 10 l.

It is also necessary to process the near-stem circle. To prevent the reappearance of aphids in the crown of the tree hang tanks with birch tar. Birch tar insecticidal agent will be effective for the destruction of moderate pests.

Herbal remedies

Many plants contain insecticidal components, which are most pronounced after insisting and heat treatment.

Infusions and decoctions:

  • Garlic. Chopped vegetable (200 g) pour water (10 l) and insist during the day.
  • Bow. Vegetable husks (300 g) insist in water (10 l) for 5 days.
  • Pharmaceutical camomile. Above-ground part (1 kg) is poured with hot water (10 l) and infused for 12 hours. From this infusion make a solution with water 1: 1 with the addition of soap (40 g).
  • Buttercup. Stems and leaves (1 kg) pour water (10 l) and insist 2 days. Filter and add 40 g of soap.
  • Tomato plant. Fresh crushed raw materials (4 kg) are placed in water (10 l). Insist for an hour and boil for 30 minutes. The broth is diluted with water 1: 1.
  • Chilli pepper. Fresh vegetable (100 g) is poured with water (1 l) and cooked over low heat for 1 hour. Broth insist 2 days, squeeze raw materials and bring to a volume of 10 liters.
  • Yarrow Dry grass (1 kg) is poured with water to complete coverage of raw materials. Stripped in a water bath for 30 minutes. After that, pour 10 liters of water and insist 2 days.

Kitchen Techniques

Kitchen called methods that use the available products. These tools are distinguished by their speed of preparation, harmlessness and relatively fast action:

  • "Coca Cola". Lemonade contains orthophosphoric acid - a strong toxin for aphids. For the procedure uses a solution of "Coca-Cola" and water (5: 1). Processing the product has a long-lasting effect.
  • Vodka. Sprayed with a clean product, and for better adhesion, you can add liquid soap.
  • Sunflower oil. The product (200 ml) is dissolved in water (10 l).
  • Tobacco smoke. For fumigation, it will be necessary to place a pile of straw or dung near the trees, sprinkle tobacco on the surface and set fire to it. The procedure lasts 2 hours and is carried out 2 times with an interval of two weeks.

Kitchen methods are economical to use small trees and shrubs or to partially treat the most affected areas.

Folk remedies to combat aphids on fruit trees

Chemicals

Many gardeners try not to use chemicals in the garden. However, with a massive pest attack, this cannot be avoided.

According to the method of penetration and the nature of the action of insecticides are divided into three types:

  • Contact. They penetrate the body of the pest through the skin when in contact with any part of the body. Most preferred for combating aphids and other piercing-sucking pests. The main drugs: Karbofos, Fury, Fufannon.
  • Intestinal. Cause poisoning if ingested with food. It is advisable to use if gnawing pests have settled along with the aphids in the tree. Popular tools: Actellic, Confidor, Bankol.
  • System. They penetrate the plant tissue and are kept there for up to 30 days. With constant contact cause the death of insects that live in the crown. In addition, toxic substances enter the body of pests through food. Differ in relative harmlessness to humans. Effective drugs: "Tanrek", "Prestige", "Biotlin", "Aktara".

A good option for certain cases of the combined drug "Nitrofen." It is a complex action that is effective against pests, fungal diseases and weeds.

Spring processing of fruit trees

Early spring processing is carried out before bud break. During this procedure it is necessary to spray the wood with the soap-and-soap solution. With a strong defeat of the tree, the ash in the solution is replaced with 80 g of kerosene.

The second treatment is carried out at the beginning of the bud. The purpose of the procedure is the destruction of young individuals hatched from winter eggs. This measure is very important and prevents the expansion of the colony to a large scale, peculiarity of aphids - high reproduction.

With a large number of pests treatment is carried out by contact or systemic drugs. If the number of insects does not cause concern, you can do with folk remedies, the consumption of which is 10 liters per average tree.

The third treatment is carried out with no effect after previous procedures or when they are missed. Especially true when the number of aphids out of control. Held twice in the opening phase of the buds and after dropping 75% of the petals. The choice of means depends on the number of insects. The following procedure is carried out after flowering, and only if there are pests on the tree.

Aphids quickly acquire resistance to the active substances of drugs, so they must be combined. It is important to ensure that there is a period of 30 days between the period of processing and harvesting, before and after the process. In parallel with these activities, it is necessary to fumigate fruit trees.

Chemical processing of trees from aphids

Autumn processing against aphids

In the autumn, it is necessary to carry out preventive measures: remove the old bark and moss from the trunk. Trim old and damaged branches. Pristvolny circle cleaned of fallen leaves, and if the tree is affected by pests and diseases, it is burned.

Autumn processing is carried out in October or in November at temperatures above -5 ° C. A 5% urea solution (500 g / 10 l) is well suited for this procedure. Additionally, it will protect the tree from the development of scab.

How to process plum and fruit trees

The gardener's task is to hit the insecticidal solution directly on the colonies by aphids. This is difficult when the leaves curl heavily. In some cases it is much better to simply rinse the tips of the shoots with a solution.

Good spraying quality is:

  • procedures carried out in the morning or evening when there is no dew,
  • treatment in windless and cloudy weather, at high temperatures the effect of the drugs is reduced,
  • no precipitation, the drug should remain on the surface of the tree for at least 3 hours,
  • work with a high-quality sprayer, which is kept at a distance of 70 cm,
  • covering the entire crown of the tree, you need to use the ladder.

It is important to protect the skin and mucous membranes from ingress of toxins and carry out processing only in protective clothing.

A fruit garden is a small ecosystem and how it will develop depends only on the gardener. Peaceful coexistence of pests and fruit crops is possible with constant monitoring of the number of harmful insects. It does not need to violate the rules of farming, it is important to timely remove plant waste and create favorable conditions for beneficial insects.

And finally, a short video on how to deal with aphids on fruit trees:

Fighting aphids on fruit trees

Destroying such a pest as aphid is quite difficult. This insect multiplies rapidly and destroys all the greens in its path - young shoots, buds and leaves.

As a result of this damage, the plants quickly weaken, wither and shrink. How to deal with aphids on fruit trees is a topic that is relevant to many gardeners.

To destroy this pest, who settled in the garden, it is possible not only by chemical preparations, but also by home methods - without chemistry.

Folk remedies

Infusion of garlic. Crush 50 garlic and dissolve in 5 liters of water. After two days, the filtered infusion will be ready for use. They irrigate the entire above-ground part of the trees and shrubs on which the aphid has settled.

Tobacco infusion. 100 g of tobacco pour 500 ml of water, insist day. Then strain and bring to a volume of 3 liters with water. Such treatment of infected plants is carried out repeatedly, especially at an advanced stage.

Infusion of onion peel is an effective remedy against aphids in trees and shrubs. The proportions of cooking are the same as for the preparation of tobacco infusion.

Tincture of nettle. 500 g of fresh leaves and stalks of nettle seedless pour 5 liters of water for 5 days. Ready infusion filter and use for processing aerial parts of plants.

Ash-soap solution. In 10 liters of hot water dissolve 200 g of ash. Boil the solution and add 50 g of chopped household soap.

Soap solution. It can be prepared as follows: dissolve 50 g of liquid or 150 g of solid soap in 5 liters of water.

Tincture of the roots of horse sorrel. 450 g of roots pour a bucket of hot water. After infusion, after 3 hours, the infusion is ready for use.
Infusion of dandelion flowers.

700 g of grass with roots and flowers pour a bucket of warm water. Let it brew for 5 hours. Then strain and use for irrigation of the aerial part of the damaged aphids of fruit plantations.

Infusion of the dope ordinary. Harvesting of grass is carried out at the beginning of flowering plants. 1 kg of dry raw material is poured with a bucket of water and infused during the day. After this, the tincture is filtered, and a small piece of soap is added to it - 30 g. This homemade product destroys the aphids both at the initial and at the advanced stage of the lesion.

You can destroy aphids in the garden with ammonia. Often the aphid appears in the trees, where there is a large accumulation of ants. These insects are interconnected. Aphids exude a sweet substance - the pad, which ants love to eat.

In exchange for this, the ants transfer the aphids from one plant to another. Thus, you can get rid of aphids, if you destroy the ants. Ammonia - a colorless solution, which in the shortest possible time helps to get rid of this pest. They are treated with places of accumulation of insects.

Coca-Cola is a carbonated drink that helps fight aphids. It contains orthophosphoric acid. For 1-2 weeks of regular spraying this tool, you can completely get rid of aphids.

The phosphorus contained in this drink is very effective against garden pests. This trace element is part of almost all pesticides and insecticides. It is complemented by an acid that these pests do not like so much.

Typically, 10 liters of water consume a tablespoon of shampoo. The result will be visible after the first processing. If necessary, the concentration can be doubled.

How to get rid of with the help of pesticides

What to do if the popular methods of struggle have not yielded any results? In this case, it is necessary to use chemical and biological preparations.

Fitoverm, Akarin, Agravertin, Actofit, Inta-Vir, Iskra and Kinmiks are the most effective and popular biological remedies for aphids.

Chemicals of systemic action seep into all tissues and cells of the plant, including the fruit. They are not washed away by rain and retain their effect for a month. These are the most effective and at the same time the most dangerous means, the use of which requires compliance with all precautionary rules.

What time is best to garden?

Evening or morning hours are the best time to perform this procedure. Treating trees from aphids during flowering is not desirable, especially if chemicals are used for this.

In this case, it is recommended to carry out preventive spraying with herbal infusions or solutions based on soap, tobacco or ash. Thus, you do not harm the future harvest and the process of formation of ovaries.

How to get rid of aphids on plum?

Very often gardeners face such a problem as aphid. It is yellowish, green, brown, pinkish and black. This tiny (no more than 5 millimeters) and inconspicuous insect can do enormous damage to your garden, even to the death of plants.

If you notice that the leaves of the plant are sluggish, twisted and deformed, there are many small bugs on their lower part, then this is a plant louse. You need to immediately learn how to deal with it, otherwise you can lose not only the harvest, but also the whole tree.

How is she dangerous?

A massive defeat of aphid trees occurs in the spring, as soon as the young leaves bloom. Это ненасытное насекомое высасывает сок из листьев деревьев и, благодаря этому, очень быстро растет и размножается.

As soon as a whole colony of aphids bred on the plant, and there was not enough food for everyone, then young individuals with wings appeared. With their help, they fly and hit other trees, breeding up to 20 times over the summer!

During its life, aphid releases sweet juice. He is very fond of ladybirds, wasps, flies and other insects. And ants even protect them, hiding in their nests or settling on other plants.

Microscopic fungi, bacteria and viruses that cause many diseases can live on sweet aphid secretions.

How to prevent the appearance?

To prevent the appearance of aphids on plum, and on other trees, gardeners are advised to take such preventive measures:

  • It is necessary to regularly destroy weeds around trees.
  • The main enemy of aphids, and our friend and helper - ladybugs. Therefore, it is worth making a little effort to create favorable conditions for them, namely: ladybugs love the smell of calendula - get this beautiful and useful flower in your garden, do not burn all the leaves and grass before winter - in them a ladybug can survive the winter in the spring to fight again with aphids.
  • In order for plants to be stronger, they need to be watered regularly, mulched and fertilizer balanced in composition.
  • In autumn and spring, tree trunks must be lime-washed before removing the old bark. Such a procedure would interfere with laying eggs for aphids.
  • Lipa and viburnum - plums are not neighbors. They are very fond of this harmful insect.
  • Near the tree trunks planted herbs (dill, parsley, coriander, for example). They will become not only a fragrant addition to your dishes, but a place for wintering ladybirds.
  • Aphid is a treat for many birds. To attract them, take care of the device birdhouses.
  • The counterpart will also help fight the pest. To attract this insect you need to plant plants from the umbrella - dill, parsley, fennel and carrots.
  • Some gardeners are advised to destroy the ants - the defenders and breeders of aphids.

How to deal with aphids, which has already settled?

If the appearance of aphids could not be prevented, then it can be eliminated in the following ways:

  1. mechanically
  2. folk remedies
  3. chemical preparations
  4. biological products.

Mechanical combat is to remove the infected leaves and wash the colonies of the insect with water from a hose.

This will help you:

  • Garlic infusion. To prepare it, you need 100 grams of garlic per 10 liters of water. After two days of infusion, you can spray the affected aphids trees.
  • The infusion of tobacco. To make it, tobacco is poured with water. Infused for 1 day, the liquid is diluted with water in a ratio of 1 to 3 and treated with infected trees.
  • Infusion of celandine mixed with tomato and potato tops. Need to insist 3 days.
  • Also aphid afraid of infusion of onion peel.
  • Infusion of nettle - take 1 kilogram of plants per 10 liters of water and insist for several days.
  • Infusion of ash and laundry soap.

Still make an infusion of hot pepper, marigold, dandelion, yarrow, sage. Fighting the pest is also spraying the tree with soapy water, and water with soda.

Treating trees with the above infusions and solutions is necessary several times in about a week. All these infusions make tree leaves tasteless for aphids.

If previous methods of preventing and combating aphids did not help you, use the chemical method - the most effective. In this case, you need to use special chemicals.

Chemical preparations are divided into:

Each of them has its pros and cons. Contact drugs - “Arrivo”, “Fury”, “Fufan”, “Karbaphos”. Pluses - aphid dies immediately, as the substance enters through the integuments of the body into her body very quickly. Cons - if some insects survive, then they begin to actively proliferate at the same hour.

Systemic drugs - Aktara. Pluses - able to penetrate the plant tissue, making the juice poisonous. Not afraid of rain, as they are absorbed instantly. Such preparations are convenient for spraying tall trees. Cons - this is a fairly long process, it can take a fortnight.

Biological preparations - "Fitoverm", "Akarin". Made from aversectin - it is a waste product of the soil microorganism. Pros - allow you to deal with aphids without harm to nature. Cons - can lose properties if they are not properly stored.

How to use the drugs?

To combat pest was not only effective but also safe, you should follow these rules:

  • First of all - follow the strict instructions attached to the drug!
  • The first spraying should be done in early spring, the second - before the blooming of tree buds, the third - before the formation of buds. If you have noticed aphids in the summer, then the treatment should be repeated, but not later than a month before the fruit ripens on the plum (cherry, apple, etc.).
  • Use a respirator. Protect also eyes.
  • Smoking and eating while spraying chemicals is strictly prohibited!
  • Treating trees with poisons in the heat should not be done, otherwise the leaves can be burned and they will fall off. Such a struggle is also unsafe for your health. The best time is morning or evening.
  • The weather should be dry and windless.
  • Remember that any chemical preparation is poison not only for aphids, but also for other insects. Therefore, be extremely attentive to the environment and use them only when clearly needed.
  • You can not process the tree when it blooms. This is detrimental to bees and other pollinators.
  • Aphids eventually get used to the drug, if it is used constantly. Therefore, it needs to be changed.

Be attentive to your plums, and they will thank you for a generous harvest!

Useful plants

Umbrella plants - dill, carrots, parsley, fennel - will come to the rescue in the fight against aphids, attracting hots. Earwigs can also be helpful. Lavender is capable of scaring green aphids, and thyme grass, planted next to the legumes, will defend against black aphids.

Nasturtium, which grows near cherry, will lure black aphids to itself, reducing the load on the tree. Chemicals should not be used unnecessarily - along with pests, their opponents will die: earwigs, hoverflies, ladybugs, ground beetles, golden eyes, horsemen, and carnivorous bugs.

Useful broths

In the fight against aphids, decoctions are effective: from wormwood, thyme, tobacco dust, tansy, yarrow, celandine, bitter pepper, dandelion, garlic, marigold, potato tops, onions, tomato tops, mustard, rhubarb (from black aphids). This requires several treatments with an interval of 1 week.

Celandine (blooming, whole plant). 300-400 grams of fresh or 100 grams of dry ground mass insist in 1 liter of water for about a day or boil for half an hour.

Pour 100 grams of dry orange or lemon peels with 1 liter of warm water and leave for the 3rd day in a warm place.

Tobacco. 40 grams of dry tobacco insist in 1 liter of water for the 2nd day, strain, adding another 1 liter of water.

Onion. Finely chopped onions (15 grams) or dry its scales (6 grams) insist in 1 liter of water for 5-7 hours in a tightly closed container, then filter.

Dandelion officinalis. (300 grams of crushed roots or 400 grams of fresh leaves insist 1-2 hours in 10 liters of warm water (no higher than 40 degrees), filter and spray.

Soap. You can simply spray it with a solution of soap diluted in soft water (rainwater) - 200-300 grams of soap per 10 liters of water or wash the tops of the shoots with a 0.5% solution of soda ash, adding 0.5% soap to it.

Remarkable in the fight against aphids and strained decoction of wood ash (300 grams of sifted ash pour boiling water and set on fire for half an hour, adding 40 grams of household soap chips).

Before use add 10 liters of water. It is possible to powder wet leaves a couple of times with ashes, to pollinate crops with a shag (15 grams / sq. M). Spray these compositions leaves should be very carefully, wetting the surface of the leaves with 2 sides.

Useful insecticides

In neglected extreme cases, we resort to treating plants with insecticides. ("Actellic" (50% cu - 10 ml / 10 liters of water), "Intravir", "Fitoverm", etc.)

Gooseberries should not be treated with colloidal sulfur and other preparations containing sulfur, since they will also cause serious burns and leaf shedding.

We get rid of aphids by folk methods

Aphids are insects up to 0.2 cm in size, black or green. In July-August, most adult insects grow wings, so the aphids fly well from place to place and infect other cultures.

The damage that aphids inflict on fruit trees, many gardeners and gardeners underestimate. Insect pierces the leaves and sucks the juice, as a result of the tissue deformed and die.

Excess water is excreted from the body of aphids in the form of sweet secretions, which have been named “honeydew” or “pad”. These secretions cover the plants and make them more difficult to breathe. In addition, they become a good basis for the reproduction of various fungi.

Even inexperienced gardeners will be able to determine that the plant is affected by aphids:

  1. At the bottom of the leaves or on young sprouts visible groups of green or black aphids.
  2. Among other insects near the plant are white scales of aphids, which the insect has thrown off.
  3. Leaves and flowers are covered with sticky substance.
  4. The leaves are crowded and then dry up, not fully bloomed. There is a fading of colors.

Folk methods

If you want to process vegetables or flowers with environmentally friendly means, then try using the following traditional methods.

Soap solution. Rub the ordinary laundry soap on the grate and dissolve it in water in a ratio of 0.3 kg of soap to a bucket.

Green potato topper. Fill with fresh or dried tops with water, leave to infuse for about 3 hours, and then spray the plants.

Bow. Cut 0.3 kg of onion finely, add the scales and pour 10 liters of water. Leave overnight, then strain and use to spray the plants from the aphids.

Chamomile is also used as a means to combat aphids. Take 1 kg of inflorescences with leaves and stems, pour 10 liters of water, leave for the night. Then one part of the solution is mixed with three parts of water and sprayed on the plants.

Celandine, mustard, tomatoes, marigolds, citrus fruits, dandelion, tobacco, garlic and other plants are widely used as folk methods of fighting with aphids.

Plant in the trees nettle and fragrant herbs. If you build birdhouses and feeders, tits, chickens, sparrows and other birds that feed on aphids will settle in your garden.

Try not to overfeed the plants with mineral fertilizers that attract aphids. It is important to monitor which plants grow near your trees, for example, onions and garlic repel aphids, and some others may, on the contrary, attract.

Chemical control methods

To effectively deal with aphids on fruit trees, there are many chemicals. At the forum, the question how to get rid of aphids was given the following answer: use the C-30 preparation. This tool is especially effective because it destroys not just an insect, but its eggs and larvae. The spraying process is carried out during the blooming of new buds.

Now you know the folk and chemical methods of fighting aphids and can protect fruit trees, as well as vegetables and shrubs from pests. Try using your own hands to prepare formulations without toxic chemicals, and if the aphid does not disappear, use ready-made chemicals. If you see damage on the leaves, tear them off or wash the insect with water from the hose.

Pest control - aphid invasions

She is teeming everywhere: aphid! It should be remembered that there are different types of aphids. Green aphids on peach trees, black aphids on legumes and green aphids on apple leaves, for example, differ from one another like a finch, a tit and a sparrow.

However, this is not all: if the aphid is harmful in gardens, it must be dealt with - using prophylactic or active remedial measures.

Various damage

Leaf aphid infects mainly young plants by sucking out cell sap. At the same time, it releases poison, which causes leaves to curl.

Since leaf aphid weakens the plant, sucking the juice, twisted tops of the branches lead to their deformation. In ornamental and orchards, this is naturally undesirable, since the correct formation of the crown of a tree is of great importance - both from an aesthetic point of view, and for obtaining a greater harvest of fruit.

Leaf aphid can also infect plants through saliva with harmful viruses. This can cause extensive damage - especially in orchards or professional rose gardens.

Leaf aphid and “discarded food”

Finally, honeydew, released by leaf aphids, plays a significant role: since leaf aphids reproduce very quickly, especially in favorable conditions, they experience a greater need for proteins.

Protein aphid receives from vegetable juices, and releases carbohydrates (sugar) in the form of honey dew. This is especially surprising when you consider that plants are typical producers of sugars, and many animals — including humans — use sugars as food to build the proteins of their bodies.

That is why we eat plants, but leaf aphids excrete sugar as waste!

Honeydew is consumed by ants (as well as flies). Therefore, ants relate to leaf aphids about the way we treat cows: they “milk” aphids to get honeydew. To do this, the ants deliberately carry leaf aphids to plants, spreading it around the garden, take care of it and even protect it.

If ants do not consume honeydew, it remains on plants affected by leaf aphids, and they are colonized by black mold, which consumes sugar.

That is why we often notice aphids on plants only in the later stages of a lesion, when the “black mold” becomes visible.

Exceptional fertility

Before we start discussing ways to combat leaf aphids, let's take a look at its completely amazing life cycle: leaf aphids hibernate in the form of eggs, at this stage we struggle with aphids in commercial fruit farms. The so-called queen comes out of the egg and produces offspring asexually!

These females also breed asexually (parthenogenesis). Only closer to the fall in the population consisting exclusively of females, males are bred, also by parthenogenesis.

Aphids mate and the last generation of females in the current year lays eggs, while the sexual generation actually dies away, however, it provides the leaf aphids with the opportunity to spread again next year.

Considering that leaf aphid gives up to 50 generations per summer, and one “virgin” female has up to six live-born young aphids per day, it is easy to understand how one queen can produce about 1,027 aphids per year - this is why aphids infect plants almost in countless quantities. However, each leaf aphid lives only five or six days.

It is also obvious why in the northern hemisphere about 450 species of leaf aphid are among the most significant pests of agriculture, forestry and gardening.

How to deal with leaf aphids?

When considering the biology of leaf aphids, it becomes clear that attempts to remove all aphids from the garden to the last - ungrateful work. As soon as you destroy the last individual, another aphid can immediately fly in from outside the garden - or it will be brought in by ants.

In all cases where this is possible, aphids should be prevented, preventing their penetration. Air vents in greenhouses and greenhouses can be tightened with gauze, which preserves the possibility of good ventilation, but does not allow leaf aphids to penetrate inside.

Some types of garden plants are resistant to leaf leaves, for example, certain types of lettuce. You can consciously choose to grow such resistant varieties.

When growing raspberries, which is also a frequent victim of leaf aphids, you can choose varieties that, although not completely resistant, are less attractive to leaf aphids. For example, the old Scheenemann variety is more likely to suffer from leaf aphids than the more modern rumiloba and otm bliss.

How to effectively deal with leaf aphids? In addition to preventive measures, you can fight with aphids directly with the help of various chemical agents. Here it is important to choose compounds that protect beneficial insects, as well as the necessary waiting period, especially when it comes to plants that are intended as food.

Waiting period: this is the time that must elapse after using a chemical agent designed to combat leaf aphids before it can be used for food without risk to health. Information about this is specified in the instructions to the chemical means of struggle.

As a rule, the waiting period is short or absent for natural ingredients (for example, potassium soap or natural oils) used in pesticides such as those produced by Neudorff, including brands such as Neudosan, Spruzit and Raptol. For more information, please contact our pesticide suppliers.

Дедушкины приемы — не все из них подходят для современного мира!

В прошлом, когда курение еще было широко распространено, Ваш дедушка мог взять сигаретный окурок и положить его на ночь в воду. Получившийся настой слегка разбавлялся водой и разбрызгивался на листья для предотвращения распространения листовой тли.

However, we can still learn from grandfather how to promote the reproduction of beneficial insects in the garden. In the piggy bank of useful grandfather receptions include the attraction of birds using the device of birdhouses (for example, for tits) and the preservation of nesting places (for example, for redstarts).

Even sparrows, whom the grandfather was not at all pleased to see in his garden, because they were thought to damage young plants, are excellent fighters against leaf aphids during the breeding and rearing period.

Attracting beneficial animals also means attracting beneficial insects. You can attract hoops by growing daisies.

Like the hotshots, ladybugs, real gold-eyed women, gall midges and horsemen are useful.

Skillful combination

The skillful combination of primary preventive measures and - if necessary - active measures to combat leaf aphids means that you can cope with these insects, even with their growing distribution.

As for those few leaf aphids, which still remain in your garden, despite these measures, that's what people say about this - there are two reasons to spice up fresh salad from your garden with chopped dill: first, it improves the taste - and besides, chopped dill masks leaf aphids, which could hide on a salad ...

What is dangerous

Despite the fact that the aphid "ignores" the berries and fruits of plants, it still causes them significant damage, sucking the juice from the top of the shoots and thereby weakening them. As a result, plants become vulnerable in the cold season, they can freeze, become deformed, etc. This can not but affect the quality and quantity of the crop.

The small size of the pest - just 2 mm - may not seem too threatening and easy to mislead. But this is the case when quantity matters a lot.

During the summer, different types of aphids give from 10 to 17 generations. From a larva to an adult aphid turns into 7-8 days, and this adult gives the next generation, with winged aphids, which move easily to new plants.

Huge moving huddles, painting the reverse sides of tender leaves in different colors - red, black, green (the color of the aphid itself) - are able to suck all the vital sap from a tree or shrub.

In addition, aphid is a carrier of viral diseases, which often destroy even quite large and strong fruit trees - a plum, an apple tree.

How does she appear on plants

Aphids overwinter on young tree branches near the buds. At the beginning of the green cone period, faded, imperceptible larvae hatch. Usually we notice that the tree was attacked by the aphid when he saw deformed, twisted leaves, where the larvae are already teeming with a dense layer.

In the early spring to find eggs laying aphids, it is worth watching ants. If on a sunny day, before the kidneys wake up, you will carefully inspect the young branches, and you will surely see ant scouts. What do ants do in early spring on a tree?

It is ants that are its malicious carriers, guards and shepherds. Often, aphids in trees appear after they are literally transported to these small, hard-working insects, which, after eating the so-called honeydew, which aphids release.

Actually, for the sake of these sugar secretions - an excess of moisture and carbohydrates - they introduce pests on plants.

In spring, aphid is hardly noticeable and it may seem that it is absent. However, in late May, adults begin to appear. They fly around the garden, forming new colonies.

Mechanical way

The easiest and simplest method of disposal of pests is to shoot them with your hands. However, it is most convenient to perform this manipulation on low plants - shrubs, flowers. Aphids from the trees is better to beat down a strong jet of water from a hose.

As you know, this is not the most effective way to combat insect pests. Let's look at other options.

Biological methods of elimination

Nature took care of and gave us natural helpers in the fight against this voracious pest: ladybugs, some species of wasps, gold-eyed larvae, tits, warblers, sparrows, cannabloes with great pleasure eat this insect.

How to do it? Seat certain plants that will attract birds or insects that eat aphids: nettle, some fragrant herbs, green manure plants (the so-called green fertilizers).

In horticulture centers or in online stores, golden-eyed larvae are sold (as experts say, a very effective remedy for aphids in the garden) and ladybirds. This method of biological control should be used only if the pests have already multiplied very strongly in the area and threaten your crops.

In order to attract birds that love to eat aphids, in open places, but not far from a natural refuge (tree or bush), you need to hang the feeders with fresh food or plant the plants that are natural food for them.

Some plants tend to repel aphids, for example, garlic and onions, and Dalmatian chamomile. It will be logical to plant them close to those crops that are under attack from harmful insects.

But nasturtium, mallow, kosmeyu, tuberous begonias aphid just loves. In no case should these crops be planted next to pest-afflicted trees. It is not necessary to plant nearby and sleeping poppy, viburnum, linden.

However, it is worth noting that aphids on fruit trees multiply so rapidly that humans should sometimes intervene in the process of protecting plants from uninvited insects.

Chemical control agents

If you did not succeed in destroying aphids in the trees by folk methods or you simply missed this point, then you will have to use chemicals.

It should be noted right away that this method is far from safe - both fruit and useful insects can fall under the gardener's sprayer. The use of chemistry in the fight against aphids is advisable only with a high number of pests, and then not always.

The garden care service at the Lenotre Park Landscape Workshop has the necessary modern and efficient equipment for treating trees and shrubs.

Gardeners together with agronomists will make the best strategy to protect your garden from diseases and pests and will strictly follow it throughout the season. Order is made by contact phone or in person.

Chemical preparations are used to destroy aphids, which are divided into:

  • Contact: suggest the penetration of poison inside the insect. This is Karbofos, Fufanon,
  • Intestinal: penetrate the pest's digestive tract, causing poisoning. Most often produce chemicals of combined action, namely contact-intestinal - Konfidor, Bankol, Spark,
  • Systemic: get inside the plant, in its cells, as well as in the fruit. There they persist for up to 4 weeks, they are not washed off either by rain or by watering. These drugs are the most effective (based on imidacloprid), but also the most dangerous. These are Tanrek, Confidant, Biotlin, Aktar (it is used not only for the direct extermination of insects, but also for the prevention of their appearance).

These aphid preparations kill even the aphids that are in the twisted leaves. Spray poisons should be no more than 2 times per season, when insects multiply the most massively - May-June.

Means have a sparing effect on the environment, because of what they are used more often. What experts recommend: Doff All in One Bug Spray and Py Spray Garden Insect Killer.

Important Tips

Before you begin to get rid of aphids in the garden, destroy the weeds growing near the area. Many gardeners have noticed that aphid appears first on them, so they are sort of breeding grounds for the insect.

Spray the tree from the aphids should be so that the underside of the leaves was well moistened.

It is not recommended to treat trees from aphids in sunny or rainy weather. The rain will quickly wash away the solution, and the sun can leave burns on the plants.

Insect species on garden trees

Among the parasites of garden trees, the following species are widespread:

  1. Green Rose Aphid - small insect with brown antennae. It affects most fruit trees and garden bushes: apple, dogrose, pear. He also loves the parasite to settle on garden roses (about what to do if aphid started up on roses, read here).
  2. Green apple aphid - the insect differs in that it has a head of chestnut or red flowers.

The females of this parasite have wings, tail and black legs. This species affects fruit trees, such as:

  • Big Peach Aphid - a microscopic insect with the body color grayish-brown. And a tiny mustache on a black head. This species can be winged and wingless. It affects fruit trees, sucking all the juices from the leaves, and the plants can lose their immunity and die.
  • Orange aphid - this parasite with a body of 2.5 mm, distributed almost everywhere, while affecting almost all the plants located in the garden. Orange aphid eats with great pleasure as a plum and cherry plum, and parsley and cucumbers.
  • Mealy Aphid - This is a small insect, covered with white bloom and with microscopic setae on the sides. This species likes to settle on citrus trees and indoor plants, while not only the leaves and fruits fall off, but the trunk itself begins to deform.

    Read more about species of aphids in here, and from this article you will learn how to deal with white aphids on indoor and garden plants.

    What harm can cause?

    The fact is that ants protect this microscopic parasite from attacks, for example, ladybirds - they eat aphids, while they themselves feed on the sweet substance secreted by aphids (read about the symbiosis of ants and aphids here, and from this article you will learn how to get rid of from the parasite with the help of ladybugs).

    It is not difficult to learn about the aphid invasion, it is enough to consider the culture.

    The presence of the parasite says the state of the plants:

    • peduncles and shoots have a brown coating, upon close examination of which insect accumulation is visible,
    • many small parasites on the inside of the leaves,
    • the curled leaves of the plant, which subsequently fall off,
    • no development of buds, they are not disclosed - as a result, the harvest can not wait.

    It is worth noting that if you do not fight with the lice, you can lose all the plants in the garden. Insect sucks juices from all cultures. The colony grows very quickly, for example, one female can give up to 20 offspring per season. As soon as there is little food on one culture, individuals appear with wings, flying to other plants, a new colony begins to multiply.

    Individuals that give birth to offspring can produce already pregnant female aphids. The insect parasite secretes a sweet juice, which provokes the development of various fungal diseases that are transmitted to plants.

    What to process?

    The land must be treated with special pest remedies without fail.. Larvae of this small parasite and black ants hibernate in the ground, which contribute to the breeding and spread of aphids.

    1. Well helps in the fight against any parasites pink solution of potassium permanganate or copper sulfate.
    2. The same can be said about the broth of tobacco.
    3. Insecticidal preparations - force, thunder, aktar.
    4. The most common way to protect the land from the larvae of aphids, which remain in the ground for the winter - is to pour around the bush a layer of furnace ash, which the aphid does not tolerate.
    5. Infusion of onion peel or garlic helps in the fight against pests, fertilizes and nourishes the soil.

    Also gardeners advise:

    • in the fall, to remove weeds and leaves, it’s good to dig up the ground before the snow falls,
    • during the summer to constantly carry out weeding.

    It is not worth fighting with aphids and black ants by burning leaves and weeds, as these insects hibernate deep in the ground.

    Effective drugs

    Aphids are treated at least twice a season.. The first spraying is carried out before the start of flowering, the second before fruit formation.

    How to spray plants? Consider chemicals that are very effective in combating the evils of aphid colonies. Chemicals - very effective, they are able to kill aphids in the most inaccessible places, or when other drugs are not effective. Most popular tools:

    1. Aktara - It is an insecticide, acting systemically and has a high toxicity. To prepare the solution is very simple - dilute 1.5 grams of the drug in a bucket of water. This volume is enough for 1 tree. The interval between treatments 10-12 days.
    2. Confidor - this drug is absorbed into the plant. To prepare the solution, you need to take 8 liters of water and dilute 1 ml of the chemical. This is on one tree, but the effect will continue for one month.
    3. Fas - tablet preparation, take 1 tablet for a bucket of water. Spraying is done every 2 weeks.
    4. Karate - an insecticide that can be used in any weather. Working solution - 10 liters of water and 2 ml of chemical. A bucket of mortar on 1 tree, again after 14 days.

    These are the most effective means, but in addition to chemicals, you can use biological and folk remedies (for more information on folk remedies for aphids, see here).

    Features of the fight

    The effect of drugs on aphids:

    • parasites begin to die when they first come in contact with the surface treated with chemicals,
    • drug penetrating cell sap,
    • with a lasting effect, systemic action.

    On sale there are drugs that destroy, not only aphids, but also other pests living in the garden (see aphids in their habitats here). But no matter how good the chemicals are, you need to understand that improperly diluted drugs can:

    • burns on the foliage,
    • drying of ovaries and flowers,
    • the accumulation of pesticides in fruits
    • adverse effects on humans.

    If pests have settled in the garden

    Before you apply the treatment of plums from aphids, you need to know how long to plan this process.:

    1. Crowns are processed for the first time in early spring, until the plant has budded, as the eggs of aphids can be under the bark or in the kidneys.
    2. The second spraying is carried out at the cone stage, during the opening of the kidney.
    3. The flowering garden is processed for the third time.
    4. The fourth time is treated at the stage of pouring the fruit. But it is worth remembering that during this period it is better not to use chemicals.
    5. After the foliage has fallen in autumn, the plum is processed last year.

    Any processing of trees is carried out early in the morning, or in the late evening, in weather, without wind and rain.

    Citrus trees are more likely to be attacked by aphids.. Ate a lemon tree growing in a pot on the windowsill, then carry out preventive measures:

    1. To carry out water procedures at least 4 times a month.
    2. When buying a new plant in an apartment, it should be quarantined in a separate place. In the plant shop, parasites can sleep, which upon awakening will spread to the lemon.
    3. Arrange a constant daily inspection of the plant, the only way to get to seize infection by aphids at the initial stage and prevent the invasion.

    Preventive measures

    Preventive measures against aphids:

    1. Everything depends on the plant itself, if the culture has a good immunity, the gardener ensures that the tree trunks are whitewashed - the plant louse is rarely divorced.
    2. As soon as the garden throws off the leaves, you need to prepare it for wintering. Remove grass and leaves - eggs and larvae can hibernate in them.
    3. It is necessary to reduce the number of black ants in the area - they contribute to the development of aphids. But it is not necessary to completely remove insects from the site, they are the only ones who will pollinate the plants in the rainy summer.
    4. To ants do not climb trees, you just need to pour ash around the trunks, which do not like many insect pests.

    How to deal with aphids on fruit trees without chemicals

    Chemical insecticides are the most effective means against parasites in orchards. However, they are not harmless to humans, which is why many gardeners prefer other, non-toxic products to combat aphids. Insect is easily vulnerable and at the initial stage of plant damage national methods of counteraction can give the desired result. Homemade methods of dealing with aphids on fruit trees are simple, their effectiveness has been tested by time.

    Soap solution with ash

    Soap solutions to combat aphids in various combinations for decades have been used in orchards. The alkali and acids contained in them have a strong insecticidal property. Suitable soap (the darker the better) or liquid. The recipe is:

    • 0.5 tbsp. ashes
    • 1 l of water
    • 4 g of dry soap or 40 ml of liquid,

    Ash pour boiling water, insist 48 hours, filtered. Add 4 g of soap, diluted in a little water. Fighting aphids involves treating fruit trees once every 10 days.

    Herbal remedies

    Folk remedies to combat aphids on fruit trees include infusions on plants that aphids do not like. This is chamomile, dandelions, horse sorrel, marigold, wormwood. In the following recipes, the amount of dry matter calculated per 10 liters of water:

    • 1 kg of potato tops with the addition of 30–40 g of soap,
    • 200 g of onion peel in combination with a handful of citrus peel,
    • 1 kg of chamomile or yarrow and 1 tbsp. l liquid soap
    • 2 кг сосновой хвои – настаивать неделю, потом разбавить водой пополам,
    • аптечный хвойный концентрат – 4 ст. л.,
    • 200 г сухих листьев табака и 40 г. шампуня,
    • 1 ст. махорки, 1 ст. золы, 1 ст. l жидкого мыла, 1 ст. l горчицы.
    • 400 г листьев и 200 г корней одуванчиков,
    • полведра измельченных бархатцев и 1 ст. l стирального порошка,
    • 400 g of horse sorrel roots,
    • 400 g of fresh aboveground parts of celandine,

    Selected components are brewed with boiling water, kept for a day (except for needles), filtered. To combat aphids, fruit orchards are treated with the obtained agent.

    Ammonia

    Ammonia is widely used by gardeners. Being a nitrogenous compound, suitable for feeding fruit crops. Spraying trees with ammonia solution helps in the fight against aphids. The mixture is toxic to insects on fruit trees, causes its death, and even useful for plants as a foliar nitrogen fertilizer. Need to stir in a bucket of water 2 tbsp. l alcohol and 1 tbsp. l any detergent. To combat aphids, it is not necessary to combine this tool with others.

    Food

    Vodka is a rather extravagant way of dealing with aphids. It is used in pure form: a sprayer is put on the bottle and processed in fruit plants. Vodka, moonshine, diluted alcohol - great help in the fight against the pest, but there is one "but": the high cost of the product.

    Gardeners noticed that vegetable oil is an effective means of combating aphids. It forms a thin film that covers the insect's respiratory organs on fruit trees, and it dies. First you need to prepare a thick solution of 1 tbsp. oil 1 tbsp. l soap composition. For spraying 4 tsp. funds diluted in 1 l. warm water. Treatment of fruit trees for aphids is carried out once a week.

    Recently, gardeners have found that spraying fruit trees with Coca-Cola or Pepsi-Cola gives a steady result in the fight against aphids. The reason for the effectiveness of soda - orthophosphoric acid, which is contained in it and is labeled on the label as the stabilizer of acidity E338. This substance quickly destroys aphids, and is useful for the plant - it begins to actively grow. From the drink it is desirable to release carbon dioxide, and for the treatment of delicate young leaves and shoots it must be diluted with water in half.

    Unusual remedy for aphids includes fragrant substances. In 50 ml of cream you need to dilute 30 drops of lavender oil or any other with a strong smell (for example, tea tree or cedar oil), add 2 liters of water. Spray fruit trees 1 time in two days.

    Aft belt from aphid

    Trapping belts on fruit trees are designed to combat ants, because they are the main hawkers of aphids. The tape soaked in glue in spring is strengthened on the trunk at a short distance from the ground, forming a barrier for insects. Belts are purchased in specialized stores or made independently. Glue retains its properties for 14-30 days. Belts should be regularly checked and replaced as necessary (or updated adhesive layer). This aphid control has disadvantages:

    • in heat the glue flows down,
    • in the rain, the belts lag behind the bark,
    • useful insects stick to the glue.

    Mechanical methods

    Their essence lies in the trapping of insects singly or in groups, and subsequent destruction. This method of dealing with aphids is effective in the initial stage of infection and with constant attention to the problem. Some of the mechanical methods on fruit trees are agronomic:

    • collection and destruction of fallen leaves,
    • Digging and loosening the soil,
    • removing old bark from a tree
    • whitewashing trunks,
    • cutting out damaged branches,
    • wound healing
    • grouse termination.

    With a slight lesion of fruit trees, aphids can be picked off by hand, washed off with a stream of water. The method takes a lot of time and effort, while ineffective: the insect will return.

    Insect enemies aphids

    In nature, aphids have enemies - insects that feed on it. Among them, the ladybird and its larvae lead, absorbing 50–100 individuals per day. Aphid is also a favorite delicacy of the golden-eyed, sandy wasps, earwigs, cicadas, crickets, hovers, ground beetles, and spiders. To combat aphids, you need to try to attract these insects to the site, to create favorable conditions for them. Sow dill, parsley and other fragrant herbs for hotshots. Earwigs will linger on the plant, near which a container with wood chips is installed - a place where they can hide. But aphid itself attracts its enemies, emitting a sweet liquid.

    Terms and processing rules

    To combat aphids during the year, fruit plants need to be processed 2 times: in spring and autumn. In both cases, you should follow the rules of spraying:

    • the event is held in the evening, in quiet, clear weather,
    • chemical solutions to combat aphids use in one day,
    • alternate preparations, preventing insect's “addiction” to poison,
    • follow the recommendations in the package instructions,
    • remove the weeds in the wheel circle before processing,
    • if there are beehives, close the openings and cover with foil,
    • processing the crown of fruit trees, ensure that a sufficient amount of the product falls on the underside of the leaves.

    Conclusion

    The fight against aphids on fruit trees is carried out in conjunction with other agrotechnical measures aimed at increasing the yield and preserving the health and longevity of the plant. This problem should be paid close attention, taking timely measures of prevention and counteraction.

    Aphid: description of insect

    Aphid is a tiny insect, perceived by the naked eye as a dark dot of 0.5 mm in size (however, some species of aphids reach 7 mm in length). In fact, this miniature bloodsucker looks like a rounded shrimp or a drop. Insect can be both wingless and wingedIn the latter case, the aphid flying organs are represented by two pairs of transparent wings: longer front and shorter rear ones.

    Shades of aphids are very different - these insects can be black, green, gray, red, pink and even transparent. The same species can change color as it grows, in addition, the color of the insect depends on the food it uses. Wingless aphid is not able to move for long distances, such an insect spends most of its life within a limited area, using long legs moving within one or more plants.

    Winged aphid becomes when the size of the colony grows so much that within the nearest territory there is nothing for the insects to feed on. Such winged individuals fly over to a new territory and form there another colony of pests.

    A pupa does not form in aphids, live insects appear either from hibernating eggs, or directly born to an adult individual (and often the aphid cub is born already pregnant).

    Aphid on fruit trees, what are the consequences

    Aphid can cause harm to the orchard, the scale of which is absolutely incomparable with the tiny size of the pest itself. Forming colonies on the inner side of the leaves, insects are able to remain unnoticed for some time, as a result of which, after the pest settlement has been detected, it is already necessary to fight with aphids on infected fruit trees. In addition to sucking the juice from the buds, leaves, young shoots, buds and flowers, aphid releases poisonous to the fruit tree. As a result, depending on the period at which the infection occurred, the buds fall off, the leaves twist into tubes and die, the buds, if they have not yet opened, simply fall off, the flowers become similar to lace napkins, the ovary does not form after such a deformity.

    If the fight against aphids on such fruit trees is not carried out, they can stop developing altogether.

    About the excretions left by the aphids on the leaves, as a result of which the process of photosynthesis is suspended, and the tree is exposed to infection by a fungus, it has already been mentioned above. The danger of aphids for fruit trees is also caused by the fact that young shoots, the juices of which the pest especially likes to eat, become so weak that they are not able to survive even a not too severe winter. Finally, a tree affected by aphids loses its overall ability to resist various diseases and other pests.

    There are separate species of aphids that form entire growths on the branches of trees — galls. Ulcers that, due to such tumors, affect the branches of a tree, can completely kill it.

    Aphids in the trees in the garden: how to deal with the pest

    There are many types of aphids, which can only be distinguished from one another by a professional scientist. Fortunately, such personification, in general, is not required, since the aphid remedies on fruit trees are excellent for any representatives of this insect. There are several different ways to deal with aphids: mechanical, biological, chemical, preventive. How specifically to get rid of aphids in trees depends on the gardener's personal preferences, the extent of damage, as well as the period when the aphids settled on the tree (budding, flowering, formation of ovaries, the beginning or end of fruiting).

    Biological ways of dealing with aphids in trees

    In nature, aphids have both helpers and enemies. It is well known that the best remedy for aphids in trees is ladybug.

    Other nurses of fruit trees are, for example, flower flies (the popular name is hoverfly), fleece (golden-eyed) and some other insects, as well as birds. Helpers in the fight against aphids can be considered red ants. They do not feed on the aphids themselves, but they destroy black earth ants, which, in turn, are not only peddlers, but also natural defenders of aphids. It is obvious that such insects and birds should be attracted in every way to your garden, or at least to avoid actions that can drive away the natural enemies of aphids. All these beneficial insects overwinter in dry grass and dead leaves, therefore, burning such organic matter in the fall, gardeners thereby destroy their "friends."

    In order to make the garden seem attractive for ladybirds, you can use some tricks: for example, you should plant tansy, nettle, dill, yarrow, daisies and other plants that like these elegant red specks between fruit trees. It is also recommended to take care of wintering for the ladybirds: for this you need not to burn, but, on the contrary, leave bunches of dry grass in the corner of the garden, ideally - corn tops. Some even find time to build tiny houses for useful insects - something akin to birdhouses, only much smaller.

    It is even easier for this purpose to twist the tube of cardboard, compacted with grass or other materials at one end and placed in the garden among the dry leaves.

    Quite an ingenious way to start ladybirds in the garden is to simply buy a package with bugs in a specialty store (insects, indeed, are sometimes specially bred for sale).

    The "reverse" way of dealing with aphids by biological methods is planting plants in the garden that the aphids themselves cannot tolerate. For example, henbane, basil, various types of elderberry, tobacco, dandelion, sorrel, horseradish, onion, garlic, mustard, wormwood, tansy and yarrow. From the colors of ala, I don’t like the smell of buttercups, marigolds, dandelions, chernobrivtsev (marigolds), chamomile, of vegetables - bitter pepper, potatoes, tomatoes. Some of these plants can be used as a basis for spraying trees already affected by aphids. For example, it is recommended to chop the wormwood stalks with a knife or shears, pour boiling water over and insist for several hours. After that, strain, add a little bit of any soapy substance to better keep the liquid on the leaf plate, and generously spray the trees, paying particular attention to the back of the leaves.

    Solution consumption per adult tree is about five liters. Aphid preparations on fruit trees can be independently manufactured in a similar way using tobacco leaves, onion peel, chopped garlic, inflorescences and chamomile stalks, dandelion leaves and roots, horse sorrel, fruits of hot peppers, celandine stems, pine needles, peel of any citrus fruits , potato or tomato tops, etc. When spraying such plant broths and infusions, it is necessary to follow some precautionary rules. First, a high concentration of the active substance or spraying in the daytime in bright sunlight can cause burns on the leaves.

    Secondly, some plants are destructive not only for aphids, but also for its natural enemies, moreover, a person can get poisoned during the procedure.

    In any case, spraying should be carried out in a protective mask and gloves and not resort to this method of dealing with aphids during the fruiting period and at least two weeks (or better - not less than a month) before harvesting.

    Chemical ways to protect the garden from aphids

    As practice shows, you can destroy aphids on trees without the use of toxic chemicals. However, in particularly difficult cases, chemical intervention may still be required.

    When choosing what to use to destroy the aphids on fruit, it should be borne in mind that, unlike many other pests, the aphid has a not too thick shell, so getting rid of it is quite easy with the help of any chemical preparation. Based on this, You should not resort to very heavy poisons.It is recommended to stop the attention on preparations containing esters. Excellent helps to get rid of aphids made on a natural basis (flax and olives) insecticidal black soap. Also well proven drugs such as fufanon and Intavir.

    It is equally important to choose the right time and method of processing. It is best to carry out the first spraying of trees before leafing.

    Further procedures depend on the degree of contamination and the gardener's attitude to the use of chemicals. In general, no more than three sprays are carried out per season, but the latter, just as with the use of natural poisons, cannot be carried out more than three weeks before harvest.

    If the pests are already visible on the foliage, the treatment is carried out by contact: this allows the insect to be killed by direct external influence on it. The negative side of this method is that its effectiveness depends on precipitation (any unexpected rain can negate all the efforts of the gardener), as well as on the thoroughness of the treatment (the poison kills only the pest with which it directly contacts). Since the aphid often hides not just on the back of the leaves, but also inside the tube in which they are twisted, the contact processing method does not allow to achieve the goal. Help in this case can come systemic insecticides that penetrate the plant sap and kill the aphids that feed on them from the inside. This method is also good because the tree quickly absorbs poison into itself, and rain cannot prevent the effective destruction of the pest.

    Nevertheless, it should be noted that any precautions when working with pesticides can not fully ensure their point action, aimed only at one insect. Any drug has its own side effects, negatively affecting other living organisms, including humans. Therefore, to resort to chemical protection against aphids should still in extreme cases.

    How to protect fruit trees from aphids folk remedies

    In addition to mechanical protection (washing off with water or shaking off hands) and spraying with plant broth, a common aphid protection is watering the leaves with infusions of ash, soap solutions (household, liquid or tar soap is used), as well as soda solutions and birch tar.

    For spraying fruit trees with similar folk remedies, 10 g of water requires 300 g of ash (for better dissolving the ash with water is boiled for about half an hour), 100 g of tar, 300 g of household soap, or 125 ml of liquid soap. Some gardeners recommend quite original ways to get rid of aphids. In particular, it is claimed that the pest dies if the tree is sprayed with vodka or Coca-Cola, a solution of sunflower oil (1 tbsp per 10 l of water), as well as water mixed with cream (1.5 tbsp. On a bucket of water) and ethereal cedar, tea tree and lavender oils (about 50 drops each in a bucket of water).

    Another popular remedy for aphids on fruit trees is fumigation with tobacco (a small fire is made of chips in a can, sprinkled with tobacco dust on top and when thick white smoke begins to fall from the can, put it under the tree). Some authors offer even more creative versions of fumigation - for this they use burning rubber, various wipers, etc. It is quite possible that the aphid will not be delighted with the fact that she was poured with vodka and Coca-Cola and fumigated with burning tires, however, I think such a radical way can help to get rid not only of aphids, but also from neighbors and households (yes and vodka in the household can be found more appropriate use).

    Therefore, it is recommended to use less radical methods for pest control, the main of which, of course, is prevention.

    Aphids on fruit trees: prevention tips

    Для того чтобы понять, как не допустить тлю в сад, необходимо выяснить, откуда она там берется.

    Занести вредителя на участок может сам человек вместе с приобретенными в непроверенных местах и недостаточно исследованными на предмет отсутствия признаков заражения растениями. In addition, insects massively penetrate the garden if untreated fruit trees grow nearby (for example, from a nearby abandoned site). The main aphid peddler is the aforementioned black earth ants. These insects are not only peddlers, but also natural defenders of aphids from other parasites, moreover, they even “allow” ala to spend the winter comfortably inside an anthill. Such a “friendship” is explained simply: ants feed on honeydew emitted by the aphids, so that the relationships between insects are built on a completely mutually beneficial basis.

    Understanding these features, it is easier to avoid creating favorable conditions for the spread of aphids in the garden.

    First of all, while treating your own garden from aphids, it is necessary at the same time (if possible) to spray unclean trees in the neighborhood, and also not to forget about your own lawn, on which the pest can also settle.

    When mowing the grass, it is recommended to leave blooming cornflowers, a shepherd's bag, wild carrots. These plants actively attract predators - natural enemies of aphids. It is equally important for ants to block access to fruit trees. To do this, you need to get rid of the entire colony, and not to fight with individual instances.

    Since black ants live in the ground, digging up the nest and treating it with poison is a good way to expel them from the plot (you can use antimole, carbolic acid, kerosene, formalin, etc.).

    Some advise sprinkling a tree around a circle with a mixture of sawdust with grated pepper, garlic or tomato leaves (it is believed that ants do not like to crawl through such obstacles), but it seems to be more effective to direct efforts to completely expel ants trees

    In general, it has been observed that the feeding relationship between ants and aphids is so stable that it can be assumed that the formula is valid: ants will leave - and aphids will also leave.
