Why does aphid appear on apples, and how to find itAn apple-tree is struck by a red-headed or gray aphid about 2-3 mm long, with a red head and a black back and tail. Eggs overwinter on the bark of an apple tree, and in spring females are born from them, which contribute to the reproduction of entire colonies on a tree. The insect females are highly fertile and can produce 40 larvae at a time. Active aphids multiply in September. Aphid attacks only those plants that have a high content of amino acids in the juice of the leaves. This may be due to a lack of potassium, phosphorus, or an excess of nitrogen. Identifying aphid on an apple is easy: the affected leaves begin to curl down, turn black and dry. Then red blisters appear on the leaves, which signify a further twisting and dying of the leaf.
Due to the defeat of the aphids, the leaves become covered with sticky liquid. This is the pad on which the ants crawl. The appearance of ants is also one of the symptoms of the presence of aphids on apple trees. In the early stages it is difficult to identify a pest on a tree, as the aphid begins to settle on top of it. Over time, when insects eat out all the fresh leaves of the apex, they descend to the lower branches, where they are easy to detect, just enough to turn over any leaf. Since, in addition to eating the leaves, this insect is a dangerous carrier of viral diseases, it is necessary to destroy the aphids on the apple tree immediately after detection.
Unfortunately, even on the most well-groomed and properly processed area there is a high probability of hitting the apple tree by aphids. Since these pests migrate through the air, they can easily fly in from neighboring areas.
How to protect seedlings and mature trees from aphidsToday, the chemical industry is actively developing and to combat insect pests, including aphids, can offer a wide range of pesticides. At the same time, experienced gardeners use folk pest control methods that have proven to be effective. In addition, biological methods of insect control are widely used as prevention. Next, we take a closer look at how to protect the apple crop from aphids.
However, considering the effectiveness of one or another method of controlling insect pests, one cannot call one method a panacea for all cases, since the effectiveness of measures depends on the conditions at the site, the number of trees and associated plants. Sometimes it is even necessary to apply all measures in the complex, because the aphid is a living organism, and it can develop addiction to one or another means.
Chemical substancesIf a large number of insects that eat aphids (for example, a ladybug) are not found on the garden plot, then it will be the most accurate way to destroy it with chemical preparations. It is very important not to miss the time while planning methods of dealing with aphids. Early spring, when the buds are just starting to bloom, and there is an optimal time to process the trees for aphids. During this period, the probability of burning the leaves is minimized, but the damage to the aphid larvae will be significant.
A very effective remedy for eliminating most species of hibernating larvae and insects is Nitrofen. It is necessary to dilute 200 g of the drug in 10 liters of water and process the infected tree before bud break. Olekuprit is also highly effective, its 4% solution also destroys aphid eggs. Before the flowering period of apple trees, Kinmiks can also be used. It is just shown to kill insects that suck the leaves from the juices and gnaw the plants.
The solution should be made according to the recommendations of the instructions, after spraying the drug will start working within an hour and protect the tree for two to three weeks. Other aphids on trees that are popular with gardeners are Karate and Inta-Vir. The first is highly economical consumption: 10 liters of solution is enough to process 1 hundred square meters of land. And the second, “Inta-Vir”, effectively fights with more than 50 types of pests, including apple aphids. A single spraying is not enough to completely destroy aphids; however, for re-treatment, sparing preparations are needed which will not burn the leaves. These include “Spark”, “Decis” and “Cypermethrin”. "Iskra" - an effective tool that will help destroy young larvae throughout the growing season of the apple tree. It is necessary to dissolve 1 tablet of the drug in 10 liters of water. You can spray the trees with this solution every 18-20 days.
How to deal with aphids on apple folk methods
Even our ancestors knew how to get rid of pests on apple trees, gardeners use their recipes today. There are many types of infusions and solutions against insect pests that can be easily prepared at home using available tools. In addition, a big plus of such solutions is that they are environmentally friendly and are suitable for those who are skeptical of toxic chemicals. Experienced gardeners have long concluded that the aphid does not attack crops under which ash has been introduced due to its potassium and phosphorus content. Therefore, it is very effective to bring under the root top dressing containing ash, as well as to spray the apple from aphids with a solution of ash. To prepare the solution will need 10 liters of water and 2 cups of pre-sifted ash. In order to better adhere the solution, you can add 50 g of rubbed soap. Stir the mass and let it stand, then spray the plant, aiming at the opposite side of the leaves.
Helps to fight with aphids grass celandine. If it grows on your site, you can prepare a decoction for spraying. Kilogram celandine pour 3 liters of boiling water, then add to the solution another 7 liters of hot water. Allow this solution to infuse for 2 days, then spray the apple tree.
Garlic solution is another remedy than can be treated with aphids. You need to chop 5-6 cloves of garlic, soak them in 1/2 cup of water, leave for 24 hours. Then add 1 tsp. liquid soap and 2 tsp. vegetable oil. Stir and dilute the resulting mass with water in a three-liter jar. Treat affected areas with a spray bottle. It is well proven in the pest control tobacco solution, which is used immediately after the detection of aphids. Take 200 grams of dried tobacco or tobacco and for two days, draw in 5 liters of water. Then strain and add another 5 liters of water and 50 g of rubbed soap. Stir well and spray the trees. Another recipe is based on the use of onion peels: 200 g of peels insist in 10 liters of hot water for 4-5 days. Spray the affected aphids trees three times every 5 days.
And the last recipe for complex aphid medicine on an apple tree, which experienced farmers consider the most effective. In a bucket of hot water, you need to dissolve 200 g of soap, a glass of steep broth of a shag, half a glass of sifted ash mixed with a quarter cup of kerosene. Even with the mass reproduction of aphids such a solution works fine.
Biological methods: what to plant under an apple from aphidsThe biological control method determines how to get rid of aphids on an apple tree using living organisms, as well as planting plants that scare them away.
Biological measures include:
- destruction of anthills. Ants are the protectors of the aphids, because they feed on the sweet pad that it emits,
- planting beside apple trees of special plants that aphids do not like. The aroma of lavender, Dalmatian chamomile, calendula, tomato, garlic or tansy scares off various pests of fruit trees, including aphids. There are also plants that are extremely attractive for aphids, which in no case can not be planted near the apple tree. These are such as nasturtium, hypnotic poppy, kosmeya, mallow, tuberous begonia, viburnum and linden,
- the construction of birdhouses and the creation of conditions for birds that peck aphids. These are sparrows, linnets, robins, tits,
- the cultivation of insects such as ladybugs, hoverflies, golden-eyed flies and some species of wasps that eat aphids.
To attract the attention of these insects and birds, you need to plant fragrant and spicy herbs and nettles next to the apple tree.
Aphid Prevention on Apple Trees
Since it is not an easy task to fight with aphids on apple trees, requiring an integrated approach, it is not superfluous to observe some preventive measures in order to minimize the risk of a repeated pest attack. Before buying planting material, you need to carefully inspect it, because aphid can get to the site along with the seedlings.Aphids can not bite through dense and elastic leaves, so timely and regular watering, application of fertilizing, mulching and sprinkling of treetops are necessary. It is also very important not to overload the apple tree with nitrogenous fertilizers, even organic ones, such as chicken dung. This also leads to aphids. Before leaving the apple orchard for the winter, it is necessary to destroy the aphid larvae that have settled for this period in the bark of the apple tree. To do this, in the autumn they are cleaning the bark of trees. Carefully, without damaging the healthy bark of the tree, scrape off the dead bark on the trunk and skeletal branches with a scraper or wire brush. First you need to lay a film so that the pieces of bark infected with aphids do not fall around the tree. Then collect everything and burn, along with the root shoots and wen, which are also cut off.
A distinctive feature of this type of aphid is that there are swellings on the places damaged by it - galls. They may be yellow or reddish. The pest itself reaches a length of about 3 mm and has a pale yellow color of the calf,
It is easy to guess from the name that the color of the calf of this type of pest is bright green, and in length it reaches no more than 2 mm. Green apple louse breeds just lightning, and can give up to 12 generations per season (this applies to areas with favorable climatic conditions), and in areas of the Urals and Siberia - up to 6. The main damage this pest causes to apple leaves and young shoots that are under their pernicious influence bend,
Red Bull Aphid
The color of the body of this pest may be greenish-brown or dark brown with a gray bloom depending on the floor. Reach a length of not more than 2 mm. However, such a small size of individual specimens does not at all prevent the red-gall aphids from causing serious damage to apple-tree plantings: as a result of its activity, not only the leaves, but also the fruits are affected. During the season, the pest gives no more than 4 generations.
Aphids and ants on an apple tree
If ants begin to warp on an apple tree, this is the first signal that aphid appears on it. The ants themselves will not bring harm to the tree, but they will help the ats to settle comfortably on the still undamaged leaves of the plant, transferring pests in the oral organs.
The fact is that ants and aphids live in a symbiotic relationship that is beneficial for both sides: aphids, when sucking juices from apple leaf plates, produce a sticky, sweet substance containing sugar that ants eat, and in gratitude they protect and place non-flying individuals on trees. In addition, they help the hell to spend the winter, taking her to the anthills. Thus, the high number of ants in the area has a positive effect on the spread of aphids.
How to get rid of aphids, control measures
Gardeners struggle with aphids on apple trees in different ways. Depending on the specific phase of the growing season of an apple tree, aphid treatment can be carried out by chemical, biological, folk and mechanical methods.
Chemicals are used mainly for spring (before bud break and when leaves appear) and autumn preventive treatments for the apple tree. The fact is that such preparations contain substances that can poison a person if they are used in terms of tree fruiting.
Aphids can appear on the apple tree already when the leaf buds are blooming. However, there are situations when the fruit crop becomes infected with aphids and in later periods of vegetation.
What to do and how to deal with a pest if it appeared on an apple tree:
At this time, it is recommended to use folk remedies for aphids, as they do not contain any chemicals. These include the processing of trees with infusions and decoctions made from improvised means, which are in store for any experienced gardener. The same means can be used to fight in the future. Below will be considered the most effective national measures to combat annoying aphids on apple trees.
For its preparation, 0.5 kg of tobacco or tobacco waste must be poured over with a bucket of warm water and left to infuse for 3 days. After this time, the infusion should be drained, and the resulting liquid diluted with another bucket of water. In order for the tobacco infusion to stick well to the treated parts of the apple tree during spraying, you need to add a little laundry soap to the solution. In order that it is better dissolved, it can be crushed on a grater.
There will need at least 700 g of dry grass. Her poured a bucket of boiling water, then leave for a few days to insist. Immediately before using the broth, filter it, heat the resulting liquid and add a laundry soap.
The smell of tomato bushes repels aphids well. To prepare the infusion it is necessary to add 5 kg of green tops into boiling water (10 l) and cook for half an hour. thus, a concentrate will be obtained, which is further diluted with water in a ratio of 1: 3, respectively. Before use, again, you need to make soap to better fix the decoction on the leaves of the apple.
Wood ash kills aphids, while being completely safe for humans.
Moreover, it can be applied under the tree in a dry form or it can be prepared from it infusion for spraying. In the first case, the ash acts as a natural source of potassium for the plant. The fact is that aphid does not tolerate a high content of this element in plants, but prefers cultures rich in nitrogen. If you periodically make a bucket of ash under the tree, then the aphid will simply get rid of the potassium contained in it.
Of course, the effectiveness of folk remedies in comparison with purchased preparations can be considered lower, but they do not contain any chemistry harmful to humans, which means that they can be used for almost the entire season, and not only at the stage of budding and blooming of the apple tree.
After the apple trees are fading away, and tiny ovaries of future apples appear on the site of the flowers, it is possible to introduce preparations of biological action for the treatment of aphids, as well as to attract aphids by various means of biological enemies.
For example, ladybirds or ground beetles.
To do this, close to the apple plantings can grow odorous herbs. Some birds can also feast on aphids, while the ovaries will not cause harm. To attract birds in the garden arrange feeders and drinkers.
Biological drugs that can be purchased at specialized garden stores include Biotlin, Entobacterin, Fitoverm, Akarin and others. When aphids eat particles of these drugs, the pests poison themselves and become sick, after which they die within a few days.
When ripe crop
Usually, two weeks before harvest, gardeners stop making any treatments for aphids. But up to this point, you can use mechanical methods, that is, removing the affected leaves and shoots manually with their subsequent burning.
It is recommended that all treatments during the season be alternated with each other, since the same favorite method used by the gardener is addictive for the pest, and therefore its effectiveness is sharply reduced.
Of course, the best thing is simply to prevent the appearance of aphids on apple trees, than to deal with them later. The first step is to carry out preventive spraying with chemicals in the spring.
It is recommended to carry out two treatments before flowering:
- the first is before budding on the branches in order to destroy the eggs of aphids,
- the second - at the time of the appearance of the first young leaves, since it is at this time that the aphid is activated.
The most effective chemicals against aphids include "Confidor", "Fufanon", "Karbofos", "Aktara" and others. Можно использовать и растворы медного купороса, но они не гарантируют эффективного уничтожения тли, зато помогут предотвратить возникновение заболеваний яблонь.
Для того чтобы не дать возможности тле перезимовать, обработку химическими средствами повторяют осенью, уже после съема урожая с яблонь. Такая профилактика поможет облегчить борьбу с тлей в следующем садовом сезоне.
Prevention by national methods
In addition to chemical treatments during the season, the following preventive measures against the appearance of aphids can be applied:
- the use of trapping belts that will help stop the movement of ants carrying aphids,
- timely destruction of weeds around the landings,
- regulation of the level of nitrogen in the soil, because the aphid prefers to eat fatty leaves,
- planting nearby odorous herbs that will scare away aphids by their smell. These include herbs, garlic, lavender, marigold and nasturtium,
- periodic treatment of apple trees with deterrent folk remedies.
The timely implementation of preventive measures will protect the planting of apple trees in the area from the defeat of aphids, which is a great danger not only for the apple crop, but also for the trees themselves.
Aphid on the apple tree - photo of an adult female and offspring
So you can call a small insect green, gray or black. The body is 2.0-3.5 mm long. Overwhelming aphid, while still in the egg. By the spring of the larvae appear small sized larvae. The juicy buds that open at this time become a “tidbit”, from which for a month the aphid on the apple tree pulls out all the juices. Proboscis - piercing-sucking apparatus. The food organ pierces not only the leaf pulp, but also young growth and even fruit. The special form of the proboscis allows sucking the juice not only from apples. Aphids feed on the useful nectar of quince, pear, hawthorn, shadberry.
With the increase in air temperature in the first month of summer, fertile female settler flock to the trees all over the garden. There is a rapid population growth. Each insect lays about 100 larvae. By the beginning of autumn, the appearance of female polonok is observed. Their larvae with sexual characteristics (males and females) are capable of fertilization. Females leave eggs for wintering.
The occupation of the tree by aphids is indicated by twisted leaves that have lost their shape. In the end they fall. Aphids are frightened by the number of individuals. Whole columns of parasites can destroy not only the harvest, but also weaken the physiological possibilities of the tree.
The most "harmful", bringing during the growing season of 3-9 generations of their own kind, are the following types of pests:
- apple green,
- red-headed gray
- striped redhead.
Seasonal methods of struggle
You can destroy aphids on an apple tree using different methods. In the first place in terms of effectiveness is spraying, which is carried out in several stages. It is mandatory performed twice a year: in the fall and spring for preventive purposes. But they do it more often.
Aphid body structure
- For the first time it is possible to spray an apple tree in the spring, until the buds have blossomed. At the same time, “two hares” are killed: the spread of the lesion by fungal infections is not allowed, overwintering larvae are destroyed. Re-processing is carried out first on the apple blossom and immediately after the end of flowering.
- Protecting apple trees from parasites need to try in the fall. Irrigation with insecticides suppresses the foci of the disease of trees, leads to the death of those who prepared to spend the winter under the bark and on the pests.
- It should be understood that in addition to the apple aphid, there are a number of other natural pests: moths, ticks, tsvetoedy, etc. The chosen remedy for aphids on an apple tree will be an effective name for this pest. For other parasites, the poison is selected individually.
Attention! The multiplicity of processing trees for each garden is determined depending on local conditions. The theory “the more the better” is not applicable here. Overloading chemicals with constant spraying can destroy the tree. This is especially true for drugs Olekupritu and Nitrofen: re-treatment of them burns young greens.
Fight for apple trees without insecticides
The first question is caused by the aphid that appeared on the apple tree: how to fight? Opponents of radical methods refuse chemicals, especially during the fruiting period.
When there is fruit, chemistry is better to refuse
In such cases, you can use the compositions:
- Urea (urea). At the earliest stage, as soon as sap flow begins. The striking effect is to burn pests, even if they are protected by a cocoon.
- Copper sulfate (copper sulfate) and Bordeaux liquid - a mixture of copper sulfate solution (copper sulfate) with lime milk. Processing takes place 15 days after flowering. Along the way, mites and other parasites are destroyed. Protection against scab, anthracnose, and moniliasis is performed.
- Ferrous sulfate (vitriol iron). Repellent, insecticidal effects, the destruction of larvae and eggs. Processing is carried out before bud break. Covers the tree completely: branches, trunk, soil in the root zone. Penetrating into the ground, supplies the apple root with deficient iron, affecting its growth, yield.
It is important to know when aphid is detected on an apple tree - how to get rid of it while rationally spending the drugs? It is considered optimal consumption of 10 liters of the composition for spraying 5 apple trees. This takes into account that the lower part of the leaves will be irrigated.
Proponents of achieving 100% quick result prefer the use of insecticidal drugs. In this case, you need to know how to treat the apple from aphids in the spring in different periods of the growing season.
- In the first month of spring, at an average air temperature of + 5- + 10 ° С, the “bare” tree is treated with Karbofos, Olekuprit, Nitrafen, Kemifos, etc. The formulation of the dilution of each drug is indicated in the instructions for use.
- In the interval between the blossoming buds and unblown buds, Apple can be saved by Ambush, Decis, Trichlorol, Phosphamide, Cyanox, etc.
- Insecticides are used when re-processing the garden in the summer. You can use one of the organophosphate Fufanon, Bi -58 new, Rogors.
Council Measures to combat pest spraying is better to use in calm and dry weather. The right time is morning or evening without active sun. The drug will have time to destroy the aphids and not evaporate.
From the experience of older generations
How to spray apple trees from aphids, using herbal infusions, household goods?
Even at this stage of defeat, you can cope with aphids on the apple tree by folk methods.
- Laundry soap is diluted in a bucket of water. The solution irrigates the entire tree: from the top to the trunk on the ground.
- Pods of red (bitter) pepper can be used fresh or dry. In the first case, they will need 1 kg. In the second - 0.5 kg. Raw chop, pour 10 liters of water and insist day. The mixture is boiled for 60 minutes, again insist day. The saturated composition in a concentrated form is stored in tightly packed bottles in a cool environment without penetration of light. The working solution is prepared from 125 g of a concentrated composition, 10 liters of water and 0.4 kg of soap (household). They are treated with apple at intervals every 2 weeks.
- Tansy, chamomile, chrysanthemum and other cultures of the Asteraceae family contain peritroids - substances that affect the nervous system of aphids when they are fed with apple juice. Cooked decoction (1 kg of fresh plants in 10 liters of water) to spray the trees. It is advisable to plant the same plants near the apple trees for a scare effect. This also applies to wormwood (bitter).
- You can fight with folk remedies using an infusion of tobacco or shag against the aphids. Tobacco leaves (0.5 kg) chop, pour water (10 l) at room temperature. Insist 2-3 days in heat. Strain. Add water (10l). Chop 0.4 kg of soap on a grater, add to the aqueous mixture. All ingredients mix well until a homogeneous composition. After spraying, the product is not washed off for a long time: soap keeps it on the foliage and bark.
- Another way to protect the apple from aphids, based on the fungicidal properties of yarrow. Dry plant (0.8 kg) poured boiling water and stand for a couple of days. Rubbed soap is mixed into the heated composition. When it has cooled completely, it can be used for spraying.
Preserving the harvest of apples from their own garden for children and grandchildren is not such an impossible task, if properly and regularly carry out maintenance work.
Where does aphid come from
On the apple tree aphid appears thanks to winged females. In areas where preventive pest control was not conducted, a large number of them appear at the end of the summer season. From there, they settle throughout the garden and develop nearby fruit plantings. During this period, insects are extremely prolific. The main task of such females to bring the sexual generation of insects.
After fertilization, the female aphid lays a small number of eggs on the apple tree, which successfully hibernate. Adults themselves die from cold. In spring, as soon as the temperature regime stabilizes, the larvae appear from the eggs at high humidity. It is they who in this period represent a serious threat to the garden. For two to three weeks, the larvae feed on sap from young shoots, buds, buds, and tender leaves.
Under favorable conditions, after 14 days each aphid larva turns into a female, which breeds a new generation of winged females (up to 80 individuals). Spreading throughout the district, they are occupying new apple trees, pears, plums, as well as fruit bushes. At the new site, females breed the next generation of pests. And so it continues until the end of the summer. Then the cycle repeats again.
Appearing on apple trees aphid can and with the help of no less harmful insects - ants. For them, the sweet honey dew emitted by the pests is a real delicacy. Therefore, ants and tend to increase the colony of small sucking insects. They guard and protect their breadwinners.
How to get rid
What to do if aphid appeared on the apple tree? Information on development cycles and pest appearance options will help you choose effective ways and methods of control. Based on your preferences, you can choose:
- The use of folk methods of dealing with aphids on apples,
- The use of modern drugs.
Of the people, the most effective are products prepared on the basis of herbs and laundry soap. The most popular among experienced gardeners is an infusion of tobacco dust with the addition of soap.
Preparation of tobacco infusion
To prepare the infusion will require the following ingredients:
- Tobacco (shag or tobacco waste will fit) - 500 grams,
- Laundry soap - 30-40 grams,
- Water - 20 liters.
The crushed leaves of tobacco are poured with warm water in the amount of 10 liters and infused for 2 ... 3 days in a warm place. After that, the resulting infusion is filtered and diluted with the remaining part of the water. A piece of soap is rubbed on a coarse or fine grater and injected into the resulting solution and mix thoroughly until dissolved. For better dissolution of soap, it is best to dilute it in 3 liters of warm infusion.
ATTENTION: Soap is necessary so that the aphid remedy reliably lies on the branches and leaves of the apple tree. This technique will not allow the first rain to wash off the infusion.
Preparation of infusion of yarrow
Another effective folk remedy against aphids, which occupied the apple orchard - infusion of yarrow. Prepare it from the following ingredients:
- Dry yarrow - 700 ... 800 grams,
- Laundry soap - about 40 grams,
- Water - 10 liters.
Before you pour the yarrow water to boil. Bay grass boiling water let it brew for several days. After that, the infusion is heated to 60 o C and add grated soap to it. It is possible to apply means after full cooling.
No less effective tool, according to many gardeners, is the ash solution. This will require:
- Ash - 3 cups,
- Laundry soap - about 40 grams,
- Water - 10 liters.
Ash and grated soap are introduced into warm water. Thoroughly mix until complete dissolution of the soap. After the solution is left for a day, two in order for it to be infused. Such a tool would be useful for apple trees not only when getting rid of aphids, but also serves as a good foliar feeding.
Use of industrial preparations
In the absence of effect from the use of folk remedies, products of industrial production will help to get rid of aphids on apples:
- Nitrofen - used in early spring before bud break. A solution is prepared against aphids at the rate of 10 liters of water with 200 grams of the product. The drug is effective against insect eggs,
- Oleekuprit - as well as the previous tool is used in early spring to destroy the eggs of aphids overwinter on apples. Spray the trees with a 4% solution of the drug,
- Spark - is used both in early spring, before bud break and after blooming. Can be used periodically with an interval of 3 weeks. The tool is perfectly safe for humans and animals. Preparing a solution at the rate of 1 tablet per 10 liter bucket of water. The working solution is enough for processing 1..5 trees,
- Decis - as well as the previous drug can be used against aphids not only on apples but also on other fruit trees and shrubs. The product is dissolved in 10 liters of water. It is enough for one treatment of 1-2 trees, depending on their age,
When and how to handle apples
An important point in the fight against aphids, is the process of processing apples. All work on getting rid of the pest is best to start in early spring. So you can destroy the overwintered eggs of insects.
You can not reuse the drugs Nitrofen and Olekuprit, as they are able to burn the young leaves. Repeat the treatment with safer means: Spark, Decis, Inta-Vir, Cypermethrin and others.
The general rule for all preparations and agents is that they should be uniformly applied on the lower part of the sheet plates. Typically, 10 liters of one or another tool is enough to process up to 5 fruit trees. Not more. Otherwise, their effectiveness will be extremely low.
Armed with our advice, you can save your apple orchard from the invasion of aphids. Consequently, the harvest will be preserved and multiplied.
What you need to know about tl
Aphids on apple trees in June are not uncommon. It was at this time that the leaves of the trees were saturated with juice, so the young greens are the greatest delicacy for this insect. If you successfully passed this period and your trees were not hit by a pest, you should not relax. The second phase of the appearance of aphids can be the end of summer - it is then that the insect often returns.
It is worth noting that pests multiply very quickly. Females can lay up to 100 larvae at a time. To prevent this, it is necessary to observe preventive measures, and if aphids are detected, immediately spray the trees.
Every experienced gardener should know what aphid is on an apple tree, how to deal with it and win. It would seem, what threat can pose an insect whose length does not exceed 3.5 mm? And the consequences can be the most sad, ranging from small-fruited crops, ending with the death of the tree.
There are several types of aphids, they differ in color and eating habits. The juice of the young leaves, shoots, fruits, they suck with a special proboscis. After that, the leaves of the tree curl into a tube, dry up and fall off.
If you do not get rid of aphids in the summer, it is safe to say that next year this attack will again be on apples and other fruit trees on your site. The insect can winter in the egg phase. In spring, small larvae will appear from it, which will infect the buds of the tree. Closer to the summer, they will turn into winged females flying around the garden and infecting all new trees.
Many are afraid to process apples with chemical solutions, but in vain. Aphid preparations have long gone through all chemical and biological tests and have proven themselves from the best side. They not only rid the tree of this insect, but also do not represent harm to the fruit.
On apple green aphid
Green aphids love to damage young trees that are just starting to grow. As a result, the leaves curl, if there are shoots, they dry up, and as a result the apple tree ceases to bear fruit. If aphid started up at the site, by the end of the summer there will be a characteristic black bloom on the tree, which is popularly called soot fungus.
Insect breeds at an enormous pace, for the season the female can give up to 10-11 generations. Do not think that the pest will die in winter. Green aphids lay eggs in the base of the kidneys, where they have a great time before the onset of heat. In early spring, larvae can be observed, and then adults.
We get rid of the pest
Gardeners need to know how to treat an apple from aphids of this particular species. This should be done in early spring, before adult individuals appeared. In this case, the ideal tool is "Nitrafen". It will destroy not only the larvae of aphids, but also the scab of an apple tree. It is necessary to spray not only tree branches, but also the soil around, it will give 100% result. If it is not possible to purchase such a product, it is necessary to spray the concentrate with green oil.
If the insect appeared in the hot season, the question arises how to treat apples from aphids in the summer. In this case, come to the aid of tobacco infusion or other popular recipe.
What is dangerous gray aphid
Gray aphid, unlike green, affects adult trees. Как правило, весной в отложенных яйцах созревают личинки, которые первым делом поражают кору яблони. Затем переходят к листьям. Тля этого вида характерного серого цвета.
Пораженные этим насекомым листья дерева вздуваются, меняют окраску, затем скручиваются и засыхают. Размножается вредитель довольно быстро, поэтому меры борьбы должны быть применены незамедлительно.
Тля на яблоне: как бороться и победить
The initial stage of dealing with this kind of aphid is the same as with green. It is necessary to process a tree. Aphid preparations should be used carefully, following the instructions exactly.
After the chemical treatment of the tree, it is necessary to remove the upper layer of bark. Then paint the whitewash barrel. In order that the insect does not reappear on the apple tree, you can put a special trap. To do this, on the trunk of the tree attach trapping belts, which are made of thick paper or straw. If the motherfucker reappears, she will definitely lay her eggs there. In late autumn, such traps must be carefully removed from the tree and burned.
Trying folk remedies
What can prevent the harvest of a good, high-quality harvest? Of course, aphid on an apple tree. How to deal with a similar insect? This is a question that lovers of growing vegetables and fruits in country houses and kitchen gardens often ask. You need to know that spraying the tree with chemical means always helps, but there are also popular recipes that also give a wonderful result.
