Aphids on plum leaves how to fight. How to get rid of aphids on trees (apple, plum, cherry): methods of struggle and folk remedies. Good spray quality

The plum is a fruit tree that produces sweet and sour fruits.

Since this tree is quite capricious, therefore, cultivation must be approached with special attention.

Plum does not like strong winds, but will bloom and bear fruit if the sun's rays penetrate it.

Aphids on the plum

Aphids are one of the most common garden and garden pests. It settles colonially on the lower part of the leaves. These are small sucking insects, widely distributed throughout the world in more than three thousand species. Always found in large numbers and attack almost any plant. Aphids on the plum do not attack the plant, but, as a rule, young shoots and weakened leaves.

By sucking the juices of the tree, the aphid grows and multiplies rapidly. When the plant begins to die and ceases to satisfy the needs of insects, the pest produces offspring that have wings (over the summer, this offspring will reproduce about 17 generations).

The insects secrete a sticky substance typical of honey nectar, which is an ideal breeding ground for gray mold and other fungal infections. The main threat to plums are also viral diseases that are spread by aphids. Every year, malware contributes to multimillion-dollar losses in agriculture and horticulture, so it's worth taking the time to learn how to deal with aphids and how to treat plums for aphids after flowering.

Aphids on the plum: how to fight in natural ways

First of all, it is very important to fight aphids, since the speed of their reproduction is lightning fast. If you do not want to resort to drastic measures and use chemicals, try to get rid of insects with natural ingredients with popular aphid control methods on plums.

So, 10 methods of dealing with aphids:

1. Garlic infusion. In order to cook it, you need to take 8-10 cloves of garlic and 5 liters of barely warm water. Garlic can be chopped a little, the effect will be better. Add it to water and wait 2 days. After that, add another 5 liters of water to the bucket and process the plum (sprinkling the leaves well).

2. Infusion of ash. For this mixture, you need to prepare wood ash (about 1 liter) and fill it with water (10 liters). Insist all day long. Then mix well, strain and add a little crushed laundry soap (5-7 grams). The resulting solution must be sprayed on the tree.

3. Tobacco. Tobacco is considered one of the best means in the fight against garden pests. You can even use leftover cigarettes or buy snuff from the store. A couple of presses of tobacco should be diluted with water and let it brew for 24 hours. The next day, you can start processing plums from aphids.

4. Infusion of nettle. To do this, you will need 1 kg of nettle and 10 liters of water. Mix and let steep overnight. The next day, proceed to the destruction of pests.

5. Infusion of onion peel. For this remedy, you will need 1 cup of husk and a bucket of a little warm water. Mix and let it brew for 5 days. After the expiration of time, you need to strain and immediately begin processing.

6. Fresh cow's milk (10 l) should be diluted with water and immediately sprayed with plum leaves.

7. Potato tops, tomatoes and celandine shoots (fresh) are poured with water (7 l) and allowed to brew for a couple of days (or more). After plentifully process the tree.

8. Soap solution of laundry soap. You will need kerosene (100 ml), 50 g of soap (a quarter of a piece) and 10 liters of heated water (boiling water). Add kerosene and soap to water and stir until smooth, proceed to the destruction of insects.

9. For this infusion, you will need horse sorrel, or rather its roots (300g) and 10 liters of water. Boil everything and let stand for 3-4 hours.

10. Infusion of chili peppers. In order for insects to stop liking the taste of juicy plums, you need to treat the tree with an infusion of hot pepper. To do this, take 6-7 liters of water and 8 pods of pepper (it needs to be finely chopped). Do not throw away the pepper seeds, but mix with the pulp in water. In order for the solution to last for a long time and allow the pests to settle again, a little soap should be added to the infusion.

And how to process aphids on the plum after flowering? This question worries many, both experienced and beginner gardeners. 15 days after flowering, the tree should be treated with a saturated soapy solution. Moreover, you can use not only laundry soap, but also liquid soap.

A weak concentration of urea is used by agronomists. 7 days after the end of flowering, you can use a solution of water and urea. Water will need 10 liters, urea 50 grams.

Do not rush and spray ahead of time. After all, you want to get rid of aphids once and for all.

How to get rid of aphids on a plum using grandmother's methods

In addition to the fact that there are a huge number of recipes for infusions from natural ingredients, there are also ways that can scare away the invasion of insects. The knowledge of our grandmothers and great-grandmothers is passed on to us, so let's find out how you can get rid of aphids on a plum tree safely for the environment and the tree itself.

Methods of dealing with aphids folk methods:

1. Many gardeners with experience attract ladybugs to their garden, they are a natural enemy of aphids.

2. Between plums, you can plant a flower such as calendula (phytoncides of this plant will suppress many types of pests);

3. The plum trunk should be treated with grease or wrapped with burlap (this is necessary in order to scare away ants, they are the carriers of aphids);

4. Many birds are very fond of eating aphids, so make houses for them on the drain, thereby doing good for animals and saving the tree from pests.

If you actively protect the tree, she will thank you with good fruitfulness.

Chemistry in the fight against aphids on the drain

Chemicals will help quickly and for a long period to get rid of a pest such as aphids. There are many ways and means, however, you should remember the basic precautions. First of all, you should wear a special protective mask and clothing. Hands should be protected with gloves. The jet of preparations should be directed to the lower part of the leaf (exactly where the aphid is located).

The following preparations, which we will consider, are used for gentle spraying. They destroy only aphids, and beneficial insects survive.

The main ones are:

1. "Akarin". It will be needed for repeated use, as it is not very stable and evaporates quickly. You will need to dilute 3 ml of the drug in 1 liter of water.

2. "Dimethoate". Belongs to the class of pesticides. For 1 liter of water you will need 400 g of the drug.

Toxic drugs include:

1. Kinmiks. Valid for up to 3 weeks (maybe more, depending on the weather). Use as directed and only freshly prepared.

2. "Inta-Vir". Able to destroy both aphids and ants. It is strictly forbidden to spray the tree during flowering. Use according to instructions.

In pest control, the main thing is not to miss the moment when the aphid is just beginning to infect the tree. It is important to respond in time to signs of leaf damage.

Plums are often attacked by pests, one of which is aphids. The first signs of the appearance of a colony are sluggish, twisted, deformed leaves, sticky branches and a large number of small bugs on the lower part of the foliage. Some mistakenly believe that aphids cannot do much harm to a strong plant, but this is not so. If the plum is not treated with anything, you can lose not only the crop, but the tree itself.

If an aphid appeared on a plum, how to deal with the invasion of pests? Consider what is the danger of a bug for a plant and how to treat a plum from aphids in order to cure a tree and prevent the spread of an insect colony.

Danger of aphids for plums

Aphids are tiny insects ranging in size from 0.5 to 2 mm, its body is colored green, brownish, yellowish or black. On the territory of Europe and our country, there are about 1000 species of aphids, among which there are wingless and winged ones. Despite the slow movement of bugs, they are able to capture a vast territory in 2-3 months if the owners of the garden do not take serious measures to destroy insects. The danger of aphids lies in causing great harm to garden plants:

Despite the fact that the aphid does not damage the fruits, it strikes the plant before the crop ripens: it sucks the juice from the green parts of the plant, destroys flower buds and buds, as a result of which the yield is significantly reduced.
In the course of their vital activity, the aphid covers the leaves and branches of the plum with a sticky, sweetish coating - honeydew, which makes it difficult for the plant to breathe.
Sweet honeydew serves as an excellent breeding ground for fungi, bacteria and viruses, which, together with insects, can destroy a tree in a short time.
Trees affected by a colony of pests weaken and may not survive the winter frosts.

The defeat of the plum culture by aphids usually occurs in early spring, when young leaves begin to bloom. Beetles suck the juice from the foliage, breed and multiply rapidly. After capturing one plant, young winged individuals fly to another and spread throughout the garden.

The appearance of aphids can also be caused by the activity of ants, which breed bugs as "milk cows" for the sake of sugar pad and protect them from other insects.

Folk ways

The easiest way to deal with aphids is to remove them mechanically, that is, manually. In this case, the infected leaves are cut off and the plant is washed with water from a garden hose. But this method can be used in cases where the pest colony has not spread throughout the tree.

When aphids appear on the plum tree, organic horticulturalists use all sorts of infusions. These drugs do not kill aphids, but have a deterrent effect.

The following are used as insecticide plants: yarrow, wormwood, tansy, pepper, mustard, dandelion, marigolds, garlic, potato tops and tomato stepchildren.

The most popular recipes for fighting aphids:

Nettle infusion. 1 kg of green nettle pour 10 liters of water and leave for several days.
Garlic infusion. Infuse 100 g of garlic cloves in 10 liters of water for 2 days, and then treat the infected trees.
Infusion from celandine. Pour celandine greens, potato tops and tomato stepsons with water, leave for 3 days and process garden plants.
Ash and laundry soap. Pour 300 g of wood ash into 10 liters of water, add a piece of laundry soap (72%).
Salt solution. Dissolve 80 g of table salt in 1 liter of water.
Decoction of capsicum. Pour 100 g of fresh hot pepper with 1 liter of water and boil for an hour, then add water to obtain 10 liters of solution.
Soap-kerosene emulsion. Mix 80 g of kerosene, 40 g of grated laundry soap and a small amount of hot water. Dilute the mixture in 10 liters of water.

Trees are sprayed with the listed means, and the treatment is repeated regularly with an interval of 1-2 weeks.

Tip: It is recommended to add a small amount of soap or washing powder to any infusion or decoction of herbs., so that the product sticks to the leaves better and is not washed off by rain.

The effectiveness of folk methods is inferior to chemical insecticides, but environmental products do not harm the environment, ripening fruits and human health.

Chemical methods

How to deal with aphids on a plum if it has bred into a large colony? It makes sense to use effective chemicals, since the choice is now great. All modern insecticides are divided into contact, intestinal and systemic. Their impact on pests occurs in different ways:

1. Contact. They enter the body of aphids through the integument of the body and act almost instantly. However, the surviving pests begin to multiply actively. Of the contact drugs, Arrivo, Karbafos, Fufan, and Fury have proven themselves well.
2. Intestinal. As the name implies, intestinal preparations enter the body of aphids while eating foliage. Good results were shown by "Confidor" and "BI-58 New".
3. Systemic. Systemic drugs penetrate the green tissues of plants and poison the juice of leaves and stems. When insects eat green mass, the poison penetrates the body of pests and destroys them. An example of effective systemic drugs are Aktara, Tanrek, Biotlin. They are quickly absorbed and are not washed off by rain, but the action of the poison stretches over time and can last more than half a month. Systemic preparations have a significant drawback - the processing of trees with such means cannot be carried out later than one and a half months before harvesting. Otherwise, the poison can get into the fruit and cause poisoning when eaten.

Tip: Any insecticide over time causes aphids toresistance(resistance) to a toxic substance and ceases to have an effective effect on pests. To prevent this from happening, periodically replace one drug with another.

Tree processing rules

Having chosen any of the chemicals, you must strictly observe the precautions when working to destroy aphids in order to harm insects, and not yourself:

strictly adhere to the dosage indicated in the instructions for the drug;
use a respirator and goggles;
do not smoke, eat or drink while working with poison;
remove strangers and pets from the site;
in case of deterioration of health and ingestion of poison into the body, take first aid measures in case of poisoning.

Regardless of the means chosen to combat aphids, it is worth adhering to the general recommendations for spraying:

The first treatment should be carried out in early spring, the second - before the blooming of plum foliage, the third - before the formation of buds. During the summer, a reappearance of a colony of insects is possible. Then the processing is carried out no later than 1-1.5 months before harvesting the fruits.
A dry, windless day is suitable for spraying plums.
It is forbidden to spray trees on a hot afternoon - poison can be detrimental to foliage, and poisonous fumes to humans.
Insecticide preparations destroy not only pests, but also other insects that do not pose a danger to garden plants. Therefore, they should only be used when absolutely necessary.
It is unacceptable to process plums during flowering, as toxic substances are detrimental to pollinating insects (bees, wasps, bumblebees).

Compliance with these rules will help minimize the negative impact of "chemistry" on human health and the environment.

Preventive measures

Aphids on the plum, as well as on other garden trees, will not appear if preventive measures are taken:

Periodically pull out weeds near trees.
Regularly water the plum and mulch the trunk circles, as well as feed with a balanced fertilizer, which will increase the plant's resistance to pest invasion.
In autumn and spring, whitewash plum trunks with lime, after removing the old bark. This measure will prevent aphids from laying eggs.
Plant thyme and lavender in a flower garden or flower bed - their smell repels aphids.
Do not plant linden and viburnum near plums - these aphids capture these plants in the first place, and then move on to fruit crops.
Sow herbs next to the trees. Dill, coriander or parsley will not only improve the taste of various dishes, but will also attract ladybugs - the main enemies of aphids. For the same purpose, you can plant calendula on the site - its smell attracts red "suns".
In order for ladybugs to settle and overwinter in the garden, it is worth leaving a piece of foliage for the winter, which will serve as a shelter for beneficial insects during the winter.
Many birds will not refuse to eat aphids. If you equip a birdhouse near the plum, the pests will have little chance of survival.

The main breeders and guards of aphids are ants. Fighting them will help reduce the risk of spreading a colony of harmful bugs on the plum.

To prevent the ants from getting on the tree, gardeners wrap the trunks with a trapping belt. This is a film 15-20 cm wide, smeared with grease or other sticky substance. Ants fall into a sticky trap and cannot move.

As an alternative, you can use birch tar, sold in any pharmacy. Ants cannot stand the smell of tar and leave the territory treated with this substance. To protect the plum from ants and, accordingly, from aphids, it is enough to apply birch tar with a brush on the tree trunk with vertical strokes, as in whitewashing. A more economical way, but no less effective, is to wrap the plum with a cloth soaked in a solution of 5 liters of water and 10 ml of tar.

Conclusion

The appearance of aphids on a plum is an unpleasant phenomenon, and it is necessary to deal with it at the first sign of a pest invasion. Each gardener himself determines which insect control methods to choose, whether it be folk remedies or "chemistry". Only timely processing will help save the plum crop and the trees themselves from small pests.

With the beginning of spring sap flow, many pests are also activated on horticultural crops. Such a disaster for stone fruit crops is aphids on plums. The ability of a tree to produce a lot of basal shoots increases the extent of the lesion.

General characteristics of the insect

The plum aphid is also called mealy aphid (Hyalopterus arundinis). This is due to its characteristic, as if dusted with flour, appearance. During the calendar year, the insect undergoes several cardinal transformations. Future spring pests emerge from autumn masonry. The wingless female lays them on the buds of a plum tree, and she herself dies. The eggs overwinter safely, and with the first greenery, individuals (females) appear on the branches, just causing harm to the horticultural crop. They are easily recognizable by their three intense green stripes along their light back. Their dimensions do not exceed 2.5 mm.

Every 10 days, females lay eggs, and a new generation of pests emerge from them. When the colony grows, insects need to expand their habitat. That's when individuals with soft wings appear from this environment and begin to populate neighboring stone fruit crops. The breeding process continues.

For good reproduction of aphids, the optimal ones are:

temperature from +23 to +27 °С;
air humidity is about 75%.

These conditions just correspond to the territory of cultivation of stone fruit culture. Plum plantations in the south of Russia and adjacent territories of the former Soviet republics suffer from mealy aphids. Plum is also cultivated in warm climatic zones. It:

Europe east and west.
Middle Asia.
Caucasus.
North Africa.
North America.
Australia.

Signs of defeat

Stone plants bloom and bloom almost simultaneously. Therefore, it is difficult to notice, if you have not seen before, white insects against the background of white foam of flowers. The whole picture opens when the tree fades - it turns out to be strewn with aphids. By the way, this type of insect does not exist on apple and pear trees, since they bloom later than stone fruits.

Aphids on the plum are located on the wrong side of the leaf and draw the juice from the cells. Literally 4-5 days after the appearance of aphids, you can see the extent of the lesion. They say about it:

yellowed veins on the leaves;
curved edges of sheet plates;
deformation and drying of branches;
the appearance of a sticky sugary film on the surface of the leaves;
excessive activity of ants that spread other pests.

The last two points are no less dangerous. These insects, firstly, eat the waste products of aphids and leave their own, and secondly, ants on trees are pest carriers. Honeydew sugary substance is fertile ground for a colony of soot fungus and other pathogenic bacteria.

Daily fight plan

To save stone fruit crops from the invasion of aphids, it is necessary to carry out systematic work. Gardeners' mistakes are:

the use of the same chemicals to combat aphids;
measures of struggle only by folk remedies;
neglect of mechanical processing.

For the success of the enterprise, it is necessary to use all types of processing. Planned and in order. This is the only way to deal with green aphids.

Order of events

1 day. Cutting and destruction of plant parts inhabited by pests. Installation of adhesive belts on the trunk to close the path for ants. Treatment of the cleared near-stem zone of a tree with the Fitoverm biopreparation. The solution is prepared at a dosage of 1 ml "Fitoverma" per 1 liter of water. The best result is achieved when spraying in the evening.

2 day. Treatment of the crown with a solution of the non-poisonous chemical preparation "Akarin". Dissolve 3 ml of concentrated product in one liter of water. It must be borne in mind that the active substance does not last long on the treated surface. To increase resistance to diseases and insect attacks, plums are fed with diluted potassium humate. Dilute 50 ml of concentrate in 10 liters of distilled water.

Day 7. The second spraying "Akarin".

Day 14. Spraying plum leaves with potassium monophosphate. The solution increases the resistance of the plant to diseases, promotes the growth of healthy leaves, flowers and ovaries. Prepared at the rate of 15 g per 10 liters of water.

21 day. Spraying with an infusion of citrus peels (lemon, orange, grapefruit, tangerine, pomelo). To prepare the infusion, the peels are crushed, poured into a liter jar by a third of the volume and pour boiling water to the top. The fertilizer is insisted for a day, then filtered, and the liquid in the jar is topped up with settled water. Top dressing is carried out with a solution of potassium humate (50 ml of concentrate per 10 l of settled water).

Pre-winter work

Revision of trees with cutting out damaged and diseased branches. Uprooting of shoots in the root zone, cleaning the near-stem circle and processing with Fitoverm.

If you can’t get rid of aphids with non-toxic chemicals, toxic ones will come to the rescue. True, they exterminate all living organisms, including useful ones. Therefore, work should be carried out in June, before or after flowering, before choosing how to process the plum from aphids. Otherwise, there will be no one to pollinate the flowers and the harvest will not wait. There are many drugs, and they are different in the method of influencing pests. They are:

contact action. These include the following: "Fury", karbofos, "Arrivo", "Fufanon", "Decis". When processing, the agents affect the surface of the body of the insect.

Systemic. For example, Aktara. It is absorbed by the plant and leads to the death of the insect through the poisoned juice. Long-acting agent, does not evaporate and is not washed off with water.

Intestinal extermination method. For this method, the preparations "Confidor", "BI-58 New" are effective. When aphids enter the gastrointestinal tract, death occurs instantly.

The first mass appearance of pests in the garden is observed in late spring and in the first half of summer. What is the danger of aphids on the plum, how to deal with these insects without endangering the future crop?

Plum pollinated aphid and other varieties

In nature, there are many types of aphids, which in one way or another harm garden and garden plantings. For plums, cherries, cherry plums, sweet cherries, apricots, peaches and other stone fruits, one of the most dangerous pests is pollinated plum aphids.

Small grayish-green insects settle on leaf and flower buds, on young shoots and on the back of already opened leaves. With a mass infection, these parts of the plant are completely hidden under a layer of pests and dead whitish scales. Feeding on the juices of the most delicate greens, aphids cause:

weakening of the shoots that become the desired prey of other pests and those suffering from lack of nutrition, the cold of desiccation more than others;
deformation of young leaves, taking the form of a spoon or boat;
massive damage to the fruit plant by soot fungus and pathogens;
early fall of foliage and poor preparation of trees for wintering;
yield decline in this and next season.

While the warm period lasts, pollinated plum aphids can give a dozen generations. At the same time, insect eggs wait out the winter not only in cracks in the bark, but also on nearby grasses, preferring cereals and reeds.

Green aphids on the plum become noticeable when the number of insects is critical. But to find a black, cherry variety that does not disdain other types of stone fruits is much easier. This pest, giving up to 14 generations, is no less dangerous. The defeat of them leads to the complete folding of the tops of young shoots, the cessation of their growth and development of foliage.

Aphids of all kinds are dangerous because they can spread quickly. Winged individuals migrate independently, and wingless ones are carried from plant to plant by ants, literally grazing aphids in the hunt for the sweet secret of insects.

The defeat of the garden by this soft-looking pest can lead to weakening of trees and loss of crops. How to deal with aphids on the plum? When and what measures should be taken to maximize the effect?

Only an integrated approach gives the best and stable results, including preventive work to protect the garden, compliance with agricultural practices and regular processing not only of plums, but also near growing crops.

Chemical agents for aphids on the drain

The sap-eating aphid plants are easily destroyed by modern insecticides. The category of agents intended to combat aphids is called aphids and includes preparations:

damaging pests upon contact with the treated surface;
penetrating inside with cell sap;
acting systemically and giving a long-term effect.

Commercially available formulations are available, can be used to destroy other enemies of the plum, and are highly soluble in water, which simplifies and reduces the cost of processing.

It is not surprising that when answering the question: “What to do with aphids on the drain?”, Many experienced gardeners speak without a shadow of a doubt about the need for urgent spraying. It's really not worth the hassle.

Without human intervention, aphids will capture the young part of the crown in a matter of days. But neglect of safety rules and non-compliance with the terms of processing threatens not only with a danger to plants, but also harm to human health.

Chemical insecticides are the only correct solution for massive plant damage, as well as in spring and autumn, when insects are not yet species. The choice of a particular preparation depends on the degree of damage to the garden, the presence of other insects on the branches, the time when aphids were noticed and the preferences of the gardener. Before you deal with aphids on the drain, you need to remember that the improper use of insecticides threatens:

burns of the green part of plants;
falling flowers and ovaries;
accumulation of chemicals in fruits;
damage to the skin, organs of rhenium and human respiration.

Therefore, no matter what remedy for aphids on the drain he uses, you must strictly adhere to the instructions, not forgetting about personal safety.

Features of processing plums from green aphids

The fight against aphids is carried out in several stages. If there are no insects on the trees, or individual individuals are found, it is not worth spraying with chemicals. Aphids, especially on small seedlings, are easily destroyed by hand or folk remedies using herbal infusions, soap or ash solutions.

A gardener who knows how to process aphids on a drain needs to imagine what time it is better to schedule such a treatment for:

The first time the procedure is carried out in early spring before the opening of the kidneys. At this time, it is impossible to see insects. But if they covered the shoots in abundance last season, it is likely that there are aphid eggs near the buds and under the crown.
Repeated fruit trees are processed at the green cone stage. At this moment, the probability of destruction of the already hatched larvae, which quickly form multi-million colonies, is high.
If in the spring measures to combat plum aphids were not taken or did not give the desired result, it is possible to spray a flowering garden when the flowers are just opening and have almost completely fallen off.

In order not to risk their own health, synthetic preparations are used at least 30 days before harvest. When the fruits are already pouring, and the degree of damage is small, it is better to use safe folk methods of pest control.

In the fall, after fruit removal, the last treatment of the year is carried out with the help of ready-made insecticides or a 5% urea solution, which is not only effective against black and green aphids on plums, but also protects trees from scab.

It is necessary to spray the trees in dry, calm weather, preferably in the morning or evening hours, when the risk of sunburn of wet foliage is minimal. When irrigating, special attention is paid to young shoots and the back of the leaves, as well as tree trunks.

How to get rid of aphids on the drain folk remedies

Before the formation of the ovary, neither folk remedies nor chemical insecticides cause harm. And how to treat the plum from aphids after flowering? An excellent alternative is proven folk remedies based on herbal infusions, soap-ash and other solutions.

To prepare a soap-ash liquid, you will need:

400 grams of sifted wood ash:
50 grams of liquid or laundry soap;
10 liters of water.

Before use, a solution that is effective for moderate pest damage is carefully filtered. Tobacco infusion mixed with soapy water will bring no less benefit. Instead of ash, you can take 10 ml of birch tar. This oily odorous substance repels insects, and also has a pronounced antibacterial effect. Good results are obtained by fumigating plantings with tobacco smoke.

Many plants contain substances that have a similar effect on garden pests as industrial insecticides. At the same time, they are safe for humans and the environment. How to get rid of aphids with plants?

To prepare such folk remedies for 10 liters of water at the choice of the gardener, you will need:

200 grams of garlic cloves;
300 grams of onions;
1 kg of vegetable raw materials based on pharmaceutical chamomile or caustic buttercup;
4 kg of fresh tomato or potato tops;
100 grams of hot capsicum;
1 kg of yarrow herb, tansy or wormwood.

An adult fruit tree consumes about 10 liters of infusion. Severely affected shoots should not just be sprayed, but immersed as far as possible in liquid so that it penetrates into the deformations formed by pollinated plum aphids.

Preventive measures against plum aphids

Since the pest migrates easily and multiplies rapidly, before treating aphids on the drain with folk remedies or insecticides, attention should be paid to:

ant control;
correct and regular pruning of the crown;
maintaining the health of the tree trunk;
digging and mulching tree trunks;
elimination of weeds and basal shoots.

There are other ways to make insects in the area uncomfortable.

Pollinated plum aphid pests not only on stone fruit crops, but also on reeds, wild cereals and other plants. Peas and beans, young shoots of beans and nasturtium, petunias, small-leaved and cultivated large-leaved linden are especially attractive to the insect. These plants are planted at a distance from plums and other fruit trees. If this is not possible, then they are sprayed along with stone fruit crops.

Among the inhabitants of the garden there are also green repellents that repel aphids. For the most part, these are essential oil plants, which include mint and basil, lavender and lemon balm, cilantro and unpretentious marigolds. Umbrella garden plants, such as carrots, fennel, dill and other spicy-flavoring herbs, perfectly lure insect predators, for which the green aphid on the plum is a welcome delicacy.

The invasion of aphids scares novice gardeners with mass character. However, with the observance of agricultural technology, maintaining cleanliness under the trees and their timely processing, insects, the number of which is easy to control, cease to be a serious threat.

Fighting aphids on plants - video

How to deal with aphids on a plum depends on the height of the tree, the degree of infestation, weather conditions, and personal preferences. The fight is carried out with folk remedies and professional preparations. Aphids on plums suck out juices, damage inflorescences, and make the tree vulnerable to many diseases.

Pests on the plum

Several species of garden aphids live on the tree.

the body size of the insect does not exceed 2 mm;
coloring black, green, brown, yellow, red;
in the middle of summer, wings appear in individuals, which indicates the beginning of the mating season.

Aphids on the plum

The life expectancy of aphids does not exceed 2 weeks. During this time, the female lays about 150 eggs. The larvae develop within a week, immediately after birth they begin to sabotage. Insects feed on plant sap, leaving behind damaged, vulnerable areas.

Twisted, deformed leaves with spots, mold, rot appear on the plum. The lack of emergency measures calls into question the yield and health of the plum.

On a note!

Aphid pests begin with the advent of heat, even before the leaves are fully blooming. Green aphids continue to live throughout the plum growing season. At the end of August lays eggs near the kidneys under the bark. In this state, the larvae hibernate.

mechanical destruction

You can destroy aphids on the drain at any time mechanically. To do this, cut off the affected leaves, twigs, new shoots. A stream of water is directed to the accumulation of insects under pressure, or sprayed with water and laundry soap from a spray bottle.

Mechanical control of aphids

In late autumn and early spring, the trunk, plum branches are carefully inspected for the presence of eggs and larvae. Around the plants they dig up the earth, water it with hot water, sprinkle with ashes.

Auspicious time to start the fight

It is necessary to monitor the condition of the tree all year round. The fight against aphids on the plum begins in early spring during sap flow. During this period, many pests wake up, larvae emerge from the eggs. It will not be difficult to process the plant, the aphids will not have time to lay new eggs.

The use of folk remedies is allowed at any stage of the growing season. Not prohibited during flowering. It is recommended to use safe products during the fruiting period. Chemical preparations should be used in early spring before flowers appear, or in early summer after flowering.

On a note!

You can save a plum with insecticides in 1 day. However, it is always necessary to weigh the pros and cons. The toxic component remains active for 20 days. If more time passes from the last treatment to harvest, a person runs the risk of replenishing his body with toxins.

How to process aphids on a plum, everyone decides for himself. There are only 2 ways - folk remedies, chemicals.

Effective folk recipes

Destruction of aphids by folk methods

You can spray the plum from small pests with a solution based on safe folk components.

Vinegar. Dissolve 200 ml of table vinegar in 10 liters of cold water, add 50 g of laundry soap. To consolidate the effect, it is necessary to spray the plum after 3 days. As a preventive measure - every month.
Tar soap. With aphids on a plum based on birch tar, you can rid the tree of rot, mold, fungi, and other pests. In 1 liter of warm water dissolve 100 g of tar soap. Add 9 liters of cool water. It does not hurt to process plums with fruits in the height of summer, closer to autumn.
Plum aphids are afraid of ash. One of the applications is to sprinkle a thick layer around the tree, dig up the ground, pour hot water. This method will help get rid of aphids on the plum when there are a lot of them. Ash poisons the sap of the plant, but for a person such a poison is absolutely safe, it also does not affect the development of fruits. The second option is to dilute 200 g of ash in 10 liters of water, add a soap base. Treat the tree with a spray gun. For prevention, repeat every month.
Garlic will help to remove aphids. It is allowed to spray the plum at any time during the warm season. A glass of chopped garlic is added to the water, insisted for a day, poured in soapy water, sprayed. They rub the bark with arrows of garlic, tie them to twigs, and scatter them around the garden.

You can also use:

ammonia;
soda;
milk and iodine;
Coca Cola;
celandine;
mustard;
vodka;
Green soap;
Birch tar;
tobacco;
boric acid.

Folk remedies involve repeated processing. The frequency of procedures depends on the degree of contamination of the garden.

Biologicals

The active components of biological products are natural substances - the waste products of bacteria, insects, fungi. They act within 10 days, there is no instant effect. Preparations are absolutely safe for humans, non-toxic for plants.

You can process a plum after flowering:

Akarin;
drug Fitoverm;
Entobacterin;
means Tanrek;
spark;
Aktara.

It is necessary to make a solution immediately before use. The product is poured into a spray bottle, watering can, spray bottle. The choice depends on the number of trees, the height of the plant.

Aphid preparations

Chemistry against pests

It is possible to defeat aphids with a strong infection of the garden with insecticidal preparations. The active ingredient is a broad-spectrum toxic substance.

On a note!

Aphids on cherry plum appear a little earlier, initially you should pay attention to this tree. Aphids on prunes are activated later. This is due to the movement of sap in the tree. The sooner this happens, the sooner the tree will become infected with pests.

It is necessary to spray the plum from aphids in early spring, even before flowering, or immediately after it. During work it is necessary to use rubber gloves, a respirator, a protective suit. Reapply in the summer.

The most effective drugs:

Karbofos;
Dimethotad;
Sharpei.

The disadvantage of chemicals is that they destroy not only aphids, but also beneficial insects, which, at the time of processing or the action of the poison, will be on the tree. For this reason, do not spray the plum before flowering. Insects that pollinate flowers die, and the yield of plums will decrease.

To reduce the number of aphids on the land, to protect the plum from infection, it is necessary to get rid of ants in parallel. It is they who spread pests throughout the trees. Attract ladybugs to the garden, which are the main enemy of aphids. To do this, simply plant dill in the garden. Grow mint, calendula, parsley on the plot. These plants repel aphids with a persistent smell.

Plum aphid is considered the most dangerous insect pest of plants, literally drinking “all the juices” from them. The small size (up to 5 mm) of a representative of the Hemiptera order can mislead those who, on their plums, have not seen the scale of the disaster caused by hordes of aphids. These are diseased twisted leaves, literally dotted with small insects. Failure to take proper control measures threatens not only the loss of the crop, but also the death of fruit horticultural crops.

omnivorous insect

This picture can be seen on any garden tree.

Aphids have chosen not only plums. All stone fruit crops (except cherries) are subject to its invasion. But the situation is best known when the plum blossomed and was covered with aphids. Dangerous for the plant and sugary coating, on which ants crawl. This is a ready-made "soil" for the development of soot fungus, viruses, bacteria. Microscopic organisms give fruits, leaves, stems an unpresentable black color.

In addition to being a voracious aphid, it is also extremely prolific. Starting from early spring, when the first greenery blooms on the trees, new pest populations appear every one and a half to two weeks. It is not difficult to recognize it: a pale green, yellow, light brown, or pink color of the back is cut off along the dark three stripes. The forces to grow and multiply are given by sap flow in plants. With a large population, when there is a shortage of life-giving food, hemiptera individuals begin to appear. They migrate well, flying from tree to tree. They leave their offspring on them up to 2 dozen times per season. In social networks, on forums, some gardeners give advice, others are looking for an answer to the question: aphids on a plum - how to fight? We offer the most proven methods for review.

Preliminary measures

In early spring and late autumn, all lagging bark, broken branches are removed. Damaged places, the trunk are whitened with lime. Egg clutches prepared for wintering are destroyed, the possibility of new deposits is prevented.
It is quite possible to influence the population size in another way. Do not dry out the soil. Carry out its mulching. The birth rate will decrease significantly if you use a complex remedy for aphids on the plum as a top dressing: dilute potassium sulfate (3 tablespoons) in water (bucket).
The space under the crown near the plums should always be kept clean, free of weeds.
In order not to attract aphids, you do not need to plant viburnum and linden near the trees. But dill, parsley, cilantro, parsnips, coriander - sharp-smelling herbs - desirable "neighbors" of stone fruits.

Plum damaged by aphids

Interesting. Processing plums from aphids in the spring with diesel fuel is a long-standing proven method. It is not used in its pure form. An aqueous solution is used for spraying even before the appearance of buds on the branches.

The first individuals that appear are washed off with water from a hose under pressure.
Deformed and twisted leaves are immediately torn off and destroyed.

Saving "chemistry"

Poisonous preparations for aphids on the plum differ in the way they act.

contact action. Fury, Karbofos, Arrivo, Fufan. Infection occurs through the upper shell of the body when the poison comes into contact with an insect. You can spray the plum after flowering from aphids again with compositions containing copper: Decis, Karbofos.
Systemic. Aktara. Through the upper covers of the plant, the reagent penetrates into the juice, leading to the death of insects that feed on it. Doesn't wash off when it rains.
Intestinal mode of infection. Confidor, BI-58 New. Defeat and death are instantaneous as soon as the poison enters the digestive tract.
It is also possible to process a plum from aphids in the spring with biological preparations based on microorganisms: Akarin, Fitoverm. Eco-friendly for humans, bees, animals.

But if the trees bear fruit, and aphids appeared on the plum - how to process it in the summer? The drug 30 is effective. It differs in the principle of action from the usual "chemistry". When processing "thirty" on the surface of the bark, a special thin cover is formed. The aphid that has fallen under it does not receive air and moisture in the right amount for life, which leads to its death.

Aphids have the ability to adapt to the repeated use of the drug

The performance of any drug decreases significantly if you use it constantly. To prevent the addiction of aphids to reagents, they must be changed periodically. No later than two decades before harvesting, all spraying with chemicals is stopped.

Attention! Aphids on the plum during flowering are not etched. Otherwise, you can kill bees, drones, and other beneficial insects that pollinate inflorescences.

Without resorting to radical methods

And if insecticides cannot be used, but aphids appeared on the plum: how to deal with natural methods? Experienced gardeners attract a natural enemy to the garden - a ladybug. To do this, plant a flower - calendula on the beds and between the trees. But ants - peddlers of aphids - should not be welcomed in the garden or in the garden. To prevent them from falling on a tree, the trunk is wrapped with burlap, corrugated cardboard, treated with insect glue or grease.

Spray plum from aphids with solutions and infusions of plants containing insecticidal components: tobacco, marigolds, tops of tomatoes and potatoes, garlic, yarrow, dandelions, etc. Cultures have repellent properties, give an unpleasant smell and taste to young leaves for aphids.

Nettle infusions and milkshakes are used against aphids.

The most effective folk remedies for aphids on the drain:

Cow's milk (1 l) is diluted with water in a volume of 7-10 l. You can immediately process.
Leaves or waste tobacco, shag, rub into dust. In equal proportions, add hydrated lime or ash (wood) to it.
It is possible to treat the plum from aphids after flowering (in two weeks) with a soapy saturated solution, provided that the primary treatment was carried out with the same composition, but only before the inflorescences bloom. For these purposes, not only household, but also green liquid soap is used.
Pour onion peel (glass) with warm water (bucket). Leave to infuse for 5 days, then strain and process.
Mince the garlic cloves. Pour half a kilogram of raw materials with water (3 l). Insist in a dark place for 5-6 days. The concentrated solution is not used, but before spraying it is diluted in proportion: 60 g per 10 liters of water. For better fixation on the foliage and the tree, crushed soap is added to it (preferably laundry soap 50 g).
If an aphid attacked a plum, starlings, titmouse and other birds that settled in the garden in bird houses made for them can become salvation.
An aqueous infusion of fresh celandine shoots, potato and tomato tops is aged for 3 days, after which the crops are processed.
You can use nettle (1000 g of raw materials per 10 liters of water withstand 3 days).
Laundry soap from aphids is used in the form of a soap solution or emulsion. Take half a glass of kerosene, a quarter of a bar of laundry soap and 10 liters of hot water. All components are mixed until a homogeneous mixture is obtained.
Pour 0.3 kg of horse sorrel roots with water (10 l), bring to a boil. Insist 4 hours.
Many gardeners try to spray the plum after flowering from aphids with a weak concentration of urea. A week after the end of the process, a solution of water (10 l) and 50 g of carbamide is used.

In the fight against aphids, the main thing is not to miss the moment of its appearance. To do this, it is imperative to carry out daily inspection of trees, respond to the first signs of the appearance of pests, know the list of aphids and how to apply them.

observe the terms of processing (they are indicated in the instructions for the chemical preparation).

Non-poisonous chemicals

To kill aphids, first try less aggressive pesticides. They exterminate green aphids, leaving beneficial insects alive:

The drug "Dimethoate" belongs to the class of organophosphorus compounds. This pesticide is effective for up to 2 weeks after spraying. It begins its poisonous effect from the very first minutes. Belongs to the third class of danger to humans. It is recommended to dilute 10 ml of concentrate per 10 liters of warm water.
"Akarin" quickly evaporates from the treated area, so this substance should be treated repeatedly. It is necessary to dissolve 3 ml of the concentrate in 1 liter of water.
Ammonia is a great helper in the fight against aphids. Dilute 50 ml of ammonia in a large bucket of water and treat the damaged areas. For greater effectiveness of the solution, add half a bar of laundry soap.

"Akarin" evaporates quickly from treated plants

These substances will save the plum not only from aphids, but also from beneficial insects:

The action of the drug "Into-vir" has a wide spectrum. Not only green aphids on the plum will die, but also ants, bedbugs, and the Colorado potato beetle. Beneficial insects that pollinate plants will die. Processing should be carried out before plum blossom and after. Dissolve 1.5 tablets of the chemical in 10 liters of water. Spray only with freshly prepared solution.
"Kinmiks" is available in ampoules. Dilute one ampoule (2.5 ml) in 10 liters of water and immediately spray the infected tree. The validity period lasts up to 25 days, then the processing should be repeated.

Aphid loves not only plums. She manages to feast on any stone fruit crops. But most often, gardeners are familiar with the situation when the plum has just faded and the tree is literally covered with aphids.

Aphids on the plum

Signs of defeat

Despite the fact that the aphid is a voracious insect, it is also prolific. In early spring, when the first greenery blossomed on the tree, after 7-10 days new insects begin to appear. To recognize them, you need to know that they have a green, yellow or pink back color. Three dark stripes run along it. If the lesion is massive, then it leads to a lack of life-giving food, resulting in the emergence of semi-coleoptera individuals. They are distinguished by good migration, moving from one tree to another. Thus, the pests leave their larvae there, from which new individuals will appear after a while. But what to do when it appeared on cucumbers, and what can be done about this problem.

Prevention

Aphid Commander

Still to be removed from the trunks of old wood and carry out whitewashing. And garden paint is perfect for this. Its advantage is that it will not be washed away by rain, and it also contains the necessary substances for pest control. All leaves that have fallen must be removed from under the tree.

Chemicals

Even before the fruits begin to ripen, it is necessary to treat the plum with chemicals. Thanks to them, it is possible to instantly defeat the pest. Such funds have a prolonged effect. In 30 days, all substances that have penetrated the fruit will disintegrate, so that the fruit can be eaten.

It is necessary to carry out spraying of trees in the morning or in the evening. If the weather is cloudy, then processing can be done throughout the day.
