How to fight aphids on currants: effective control methods, chemical and folk remedies. What to do if aphids appear on currants, how to fight

Since early spring, summer residents have a lot to worry about: watering, weeding and pests. When the first leaves on the currants bloom, aphids immediately appear. The pest settles on young shoots, which become deformed and dry out. The currant harvest is declining. What to do and how to fight aphids on currants?

How to detect aphids on currants

Most often, gall aphids, a small sucking insect, settle on currants. Aphids feed on young shoots and currant leaves. You can find a colony of pests on the bottom of the currant leaf. Red or yellow swellings and tubercles—galls—form on damaged leaves.

Around mid-July, when the currant leaves stop growing, the aphids develop wings. At this moment the pest leaves the bush. If there are a lot of weeds around the plantings, gall aphids will move to them, where they will feed until autumn. During the season, more than one generation of pests is hatched, which in the fall, around September, migrate back to the currant bush. The females begin laying eggs.

Gall aphids on currant bushes are a great danger, especially for young plants. Immature bushes affected by a large number of pests are unable to develop normally. The yield of adult bushes drops sharply, the berries become smaller.

How to fight aphids on currant bushes

One of important factors When fighting gall aphids on currants, prevention is the key. From early spring, it is necessary to carry out basic preventive measures:

Be sure to remove all weeds under the bushes;

Conduct sanitary pruning bush, cutting out all diseased branches;

Attract beneficial insects that feed on gall aphids, for example, ladybugs;

Scald the bush with boiling water in spring.

Important! If ladybugs and lacewings have settled on currant bushes, then insecticides must be used carefully. It is better to replace them with herbal infusions. Beneficial insects will help quickly get rid of aphids.

By attracting beneficial insects to the garden, you can get rid of gall aphid without resorting to chemicals. To attract insects, experienced gardeners practice planting medicinal plants under the currant bushes:

Marigold;

Allisum;

Yarrow;

Many insects that are beneficial to the garden prefer to live in dill or buckwheat plantings.

How to get rid of aphids on currant bushes: fumigating the garden

Very often, one of the methods of combating aphids is to fumigate the garden. Experienced gardeners They practice fumigation with rubber, tobacco and mushrooms.

Fumigation should be carried out before the buds open, at the moment of their opening.

Fumigation with rubber is carried out as follows: put a bush of rubber in an old pan and leave it to smolder under each currant bush.

Fumigation with tobacco and mushrooms is carried out using a beekeeper's smoker.

You need to fumigate the garden for at least three hours. This should be done in the evening, in calm weather. The aphids die completely; there is no need to use chemicals.

The disadvantage of this method is the acrid smoke, which has a bad effect on human health.

Fighting aphids on currants: treating bushes with chemicals

Chemicals that need to be applied in several stages will help get rid of gall aphid colonies on currants. Use chemicals Only necessary in advanced cases and massive pest attacks.

1. The first spraying of currants is carried out in the spring, at the time of bud bloom.

2. The treatment should be carried out a second time when the bush is flowering.

3. It is better to spray currants for the third time immediately after flowering.

4. Last processing should be carried out only after the harvest is complete.

How to treat currants against gall aphids?

For treatments, chemicals are used that are dissolved in water. The following drugs have proven themselves well:

Actellik (dilute 15 ml per 10 liters of water);

Novaktion (dilute 5 ml per 10 liters of water).

Folk remedies for fighting aphids on currants

Applying folk remedies in the fight against aphids, you can get rid of the pest without interfering with beneficial insects. For these purposes, the following infusions are used:

Tobacco infusion;

Infusion of marigolds;

Red infusion hot pepper;

Infusion of tomato tops;

Infusion of onion and garlic;

Ash infusion with wormwood;

Soda ash solution;

Infusion of celandine.

1. Tobacco infusion

An infusion is prepared from tobacco dust or shag, with the addition of laundry soap and water. To do this, pour 500 grams of tobacco dust into 10 liters of water and leave the mixture for several days. The finished infusion is filtered, diluted with 10 liters of water and 100 grams of grated laundry soap is added as an adhesive.

Spraying is carried out in the evening, at clear weather. After rain, repeat the treatment.

2. Infusion of marigolds

An infusion of marigolds, which is prepared from dried flowers, is very effective in combating gall aphids. For a 10 liter bucket take ½ part of the crushed marigolds, which are poured warm water. Infuse the mixture for three days. The finished solution is decanted and 50 grams of grated laundry soap is added.

3. Red infusion hot pepper

You can prepare a concentrated infusion from red capsicum. To do this, 1 kg of fresh pepper needs to be cut and placed in a pan, pour 10 liters cold water. Bring the mixture to a boil and cook over low heat for 1 hour. The cooled solution is stored in a warm place for several days. The finished solution is filtered and stored in the cold.

For spraying, a working solution is prepared from the concentrate. For 10 liters of water use 1 glass of concentrate. You can add grated laundry soap to the solution as an adhesive.

Important! The ready-made working solution and red hot pepper are used not only in the fight against aphids. It is good to use against slugs.

4. Infusion of tomato tops

Tomato tops make a good infusion for controlling gall aphids on currants. To do this, dry tomato tops, about 2 kg, and fresh tops, 4 kg, are crushed and filled with 10 liters of water. The mixture is boiled for 30 minutes. The resulting concentrate is cooled and stored refrigerated. Before spraying, prepare a working solution. To do this, the concentrate is diluted with water in a ratio of 1:5, adding grated laundry soap.

Important! A working solution of their tomato tops concentrate can be used to combat mites, cutworms, codling moths, cruciferous flea beetle and gooseberry sawfly.

5. Infusion of onion and garlic

Experienced gardeners advise spraying currants with an infusion of green onions. To do this, pour 1 kg of chopped onion into 10 liters of water and leave the mixture for 6 hours. Strain the prepared solution and spray.

You can use pre-prepared onion skins. For this, 500 gr. The husks are infused in 10 liters of water for about 5 days.

Important! Infusions of onions and garlic not only fight pests on currants, but also increase plant immunity.

6. Ash infusion with wormwood

Affected currant bushes are treated for aphids ash solution with the addition of wormwood. To do this, pour 500 grams of crushed wormwood with water, about 5 liters, adding 1 glass of ash and 50 grams of laundry soap. The mixture is infused for about 5 hours. Spraying is carried out with a working solution, which is prepared from 1 part infusion and 2 parts water.

7. Soda ash solution

You can treat currants against aphids with a soda solution. Prepare a working solution from 1 tbsp. l. soda ash and 1 liter of water.

Spraying with this solution will help not only get rid of aphids, but also drive away the fungus from the bush.

8. Infusion of celandine

Summer residents fight aphids using celandine infusion. Prepare a solution from 4 kg of fresh celandine herb, which is crushed and filled with 10 liters of water. The solution needs to infuse for a day. Ready solution spraying currant bushes.

Important! When treating currant plantings with celandine solution, it is imperative to use personal protection, since celandine juice is very poisonous.

What you need to consider when treating currants against gall aphids

Young currant shoots bend well, they can be dipped in any recipe prepared and washed well, without the risk of breaking the branch.

You need to spray and wash every branch, without missing a single section of the bush.

You need to spray not only the bush, but also the soil underneath it.

The weather during processing should be calm. When using chemicals, keep an eye on the bees. It is important not to poison beneficial insects, which are very necessary in the garden. It is better to postpone spraying to the evening, when the bees are no longer flying.

When spraying, be sure to wet the bottom of the leaf; to do this, point the sprayer inside the bush.

Should not be placed big hopes on traditional methods combating aphids on currants if time is lost and the pest has chosen roses, plums and gooseberries. In such a situation, you cannot do without the use of chemicals.

In the fight against aphids on currants, it is important to monitor the cleanliness of the area, to prevent a riot of weeds and the proximity of shrubs to anthills. Carry out preventive spraying with herbal infusions more often, monitor the density of the bush and cut out diseased branches in a timely manner.

Currants are quite unpretentious garden culture, which bears tasty and healthy fruits.

Caring for it is not difficult and uncomplicated, although sometimes it is associated with troubles and disappointments in the form of aphids on currants. How to treat a shrub to save it from pests? Is it possible to take preventive measures to prevent their occurrence?

Before you find out effective ways, how to treat aphids on currants, let's find answers to such important meaningful questions: what do aphids look like and why do they appear on currants? What are the types of pests and how to recognize that a bush is affected by them? Let's find out.

What are aphids

The body of insects is soft and uneven, without protective layers, covered with small growths and fluff.

Pests are divided into two types:

Leaf gall aphid.
Gooseberry fruit aphid.

Pest danger

It is important to do this as early as possible, since insects are capable of multiplying at lightning speed and quickly damaging the bush. How does this happen?

Each individual aphid is equipped with a mouth proboscis, with which it pierces young greenery or tender shoots to suck out the sap of bushes. This occurs throughout the warm season, from spring to autumn.

When there is not enough food, the aphids develop wings and fly from the currant bush to nearby weeds. However, in the fall, the harmful family will still return to their “father’s house” to begin laying eggs. At this time, males appear and fertilize females for further procreation.

By sucking the vital juices from the stems, the colony of pests oppresses the bush so that it is unable to develop normally. The currant leaves begin to become deformed, the plant withers and dries out, stops bearing fruit and eventually dies.

How can you identify damage to a bush in the early stages and help the diseased plant?

Signs of pests

First of all, it is necessary to regularly and carefully inspect currant bushes: aphids are always hidden on the inner (bottom) side of the leaves.

What other signs should you look for before starting a rescue operation? Here are some of them:

the growth of seedlings stopped for no reason;
branches are bent and deformed;
the shape of the leaves is twisted and distorted;
With outside leaves swell, red or yellow spots form;
Dried shoots predominate in large numbers.

What are the reasons for the appearance of aphids on currants (we will learn how to treat and how to save the shrub a little below)?

Reasons for appearance

To find out what preventive measures need to be taken to prevent aphids from appearing, it is important to know the causes of their occurrence. They may consist of the following conditions:

Universal methods

loosening the soil near bushes, destroying dry and dead shoots;
eliminating weeds around currant seedlings;
manual removal of pests from affected foliage (manually or with a water jet);
attraction to garden plot insects that feed on aphids and other pests (for this, marigolds, tansy and yarrow can be planted in close proximity to currants);
treating shrubs with homemade solutions or pesticides.

Now let's discuss these methods in more detail.

Boiling water to help

In most cases, you should worry about the currant bush in early spring, before the appearance of flowering buds.

How to treat currants against aphids in spring? First of all, you can think about scalding the bush with boiling water. However, this must be done even when the kidneys are not swollen.

Where should I start? It is necessary to heat a lot of boiling water (several buckets or barrels), pour the water into an iron watering can and start watering.

This is not an easy matter. Because scalding currants should begin from the upper branches, and for this you will need to stand on a chair or bench. In addition, it is important to remember that you will need a lot of boiling water, since one bush can require an average of eight to ten liters of water.

But the effect is worth it. Treatment with boiling water will help kill not only aphids, but also kidney mite, and other unpleasant pests.

Fumigation

What else can you use to treat currants against gall aphids? Fumigate the garden. The essence of this method is that the affected bushes are exposed to acrid, thick smoke, which is formed as a result of the combustion of various substances. Thanks to this, all unwanted pests die.

Fumigation can be carried out using rubber, tobacco or mushroom. In the first case, the lit rubber is placed in an unnecessary non-flammable container and placed under each bush. For tobacco or mushrooms, a beekeeper's smoker is used.

It would seem that fumigation is a fairly simple and easy method, but it is important to remember some nuances:

The process must be carried out in the evening, when there is no wind.
You should set aside at least three hours for fumigation.
If a mushroom is taken as the main combustible substance, then it should be a large, well-ripened puffball.

In addition, the slow smoldering method is applicable only in early spring. But what if you discovered the pests much later? How to treat currants against aphids after flowering?

Spraying with pesticides

There are several dozen types of synthetic drugs that can destroy huge colonies of harmful insects. When using these substances, several rules must be followed:

It is necessary to apply the products in several stages: before the buds appear, during flowering, immediately after flowering and after harvesting.
Pesticides should be used in particularly advanced cases: when too many aphid colonies are found on shrubs, when other methods do not work, and when pests reappear.

What specific insecticides can be used to treat aphids on currants? The more you know about the proposed remedy, the better. Before buying a particular pesticide, it is important to collect objective reviews about it, as well as carefully study the instructions for use.

The most commonly used products are: “Karbofos”, “Akarin”, “Aktellik”, “Biotlin”, “Tanrek”, “Aktara”, “Decis Profi”, etc. Some of them can be used to treat aphids on currants in June. The more carefully you read the instructions regarding this issue, the better. Since not all preparations can be used during the fruiting period or immediately before picking berries.

Although each insecticide should be diluted according to the instructions attached to it, there are general rules spraying currants with toxic solutions.

How to treat shrubs

Here are some specific tips for different types spraying:

Dip each currant sprig into a bucket of diluted solution.
Spray each shoot with a spray bottle (and even the soil under the bush).
It is important to predict weather conditions (so that there is no wind or rain in the near future).
Use protective equipment during processing: mask and gloves.

In addition to pesticides, there are other effective means, which can be used to treat black currants against aphids. How are they different from chemicals? First of all, because they are safer for human health.

Folk methods of struggle

Before treating currants against aphids with folk remedies, it is important to decide what substance you want to use to control pests. As practice shows, it is not necessary to choose just one method. To find out which remedy is most effective, you can alternate infusions prepared from different components.

Garlic infusion. Grind two large heads of garlic in a meat grinder, stir in a bucket warm water and let it brew for 24 hours. Treat the affected shrubs with the strained infusion daily for two to three weeks.

Citrus infusion. Finely chop the frozen peel of 1 orange and pour 1 liter of boiling water. After cooling, add two drops of liquid soap.

Infusion of celandine. Grind four kilograms of fresh herbs, add a bucket of water and leave for 24 hours.

Infusion of ash and wormwood. Pour half a kilogram of finely chopped grass into five liters of water, add a glass of wood ash and fifty grams of laundry soap. Let it brew for five hours. After this, mix the resulting infusion with water (in a ratio of 1:2) and process the currants.

N hot pepper infusion. Finely chop one kilogram of fresh red vegetable, add ten liters of water and cook over low heat for an hour. Then put it in a warm room for several days. After this, strain the infusion and mix with water (one glass of infusion per ten liters of liquid). If desired, you can add grated laundry soap to the prepared solution.

Forecast

In addition, an important way to eliminate aphids will be regular preventive measures, which were mentioned in this article. Then no pests will be able to affect the health and fruiting of your currants.

Ugly swellings and growths on the leaves of red currants at first glance look like a disease, but it was the gall aphid that was at work. Feeding on the juices of the plant, it causes its deformation - traces of vital activity look like healed wounds. The worst thing is that the voracious and prolific insect prefers young shoots, which means it harms not only current state bushes, but also reduces the chances of good harvest in future.

Description of the insect, its harmfulness

The leaf gall aphid is one of 4 thousand species of the aphid family that live on the planet. The distribution area of the redcurrant pest is Europe, the Caucasus, Siberia, Central Asia, and is currently found wherever this berry bush is grown.

The food source and host plant for the species are red and white currants; sometimes they can slightly colonize black currants. As a facultative (intermediate) plant, it uses herbs of the Lamiaceae family. In the second half of summer or if the colony is overcrowded, the aphid colonizes mint, sage, oregano, thyme, and lavender growing nearby, and is very fond of thyme.

In structure and appearance, gall aphids are similar to their many relatives. small insect ovoid in shape reaches a length of no more than 2–2.3 mm. The majority of representatives are wingless; winged individuals appear in later generations. Among the differences are a pale, greenish-yellow, almost transparent cover, as well as the presence of small hairs on the body, which is why it is also called hairy.

During the season, from 4 to 19 generations of the insect develop - the warmer the region, the more. It is its fertility that aggravates its harmfulness. One single founder aphid gives life to tens, or even hundreds of thousands of sucking pests. What is the extent of damage from gall aphids that have settled on currants?

By sucking out the juices, it depletes the shoots. To “heal” wounds, the plant produces special tissues that form growths at the site of damage - galls. If aphids are not controlled, they will spawn new generations and live on the branches until they dry out.
Attracts other pests to the garden, such as ants. Not only do they “graze” aphids, protect their entomophages, and contribute to their spread, but they themselves also feed on the juice of strawberries or grapes.
Gall aphids can be carriers of pathogens viral infections plants.

Young shoots infected with aphids, even after the destruction of the pest, lag behind in growth, take a long time to recover, and therefore their productivity decreases.

Note! The threat of aphids are entomophagous insects, in particular ladybugs, lacewings, and hoverflies. But if the colony is guarded by ants, they will not let them get close.

"Family" hierarchy of gall aphids

The life cycle of leaf gall aphids is characterized by the phenomenon of polyformism. This means that different generations of an insect can differ not only in appearance, but also perform different functions. What does the hierarchy of aphids look like throughout the growing season and the full transformation cycle?

The founder aphid hatches from an egg. She is the “foremother” of all generations that will appear during the season. This is a parthenogenetic individual, and is also viviparous, i.e. it gives birth to ready-made insects and only females, which in turn produce the next generation of offspring.
Virgin aphids represent the bulk of gall aphids that we observe on currants. They do not have wings, so the insects are constantly on the host plant; parthenogenetic females give birth to their own kind.
Dispersal aphids are a winged generation; they perform a slightly different function. When the colony grows or the food supply is depleted, they fly to a new place and establish the next settlement.
Aphids are a transitional generation of insects that produce females capable of laying eggs and males.
Female aphids and male aphids are a bisexual generation that provides wintering for the species. Founder aphids emerge from eggs laid in the bark of currant stems in the spring.

How does the pest develop?

The leaf gall aphid lays its eggs under the bark of red currant branches, closer to the buds. Here it depends on the climate zone and weather conditions can be up to 9 months. In the spring, as soon as the buds begin to bloom, the foundresses emerge from the eggs and populate the plant.

Active reproduction of the insect begins from the moment the bush blooms. The peak of harmfulness occurs in June, when the colony reaches its maximum sizes. In the second half of summer, currant leaves become coarser, and aphids begin to spread to intermediate plants. Several more generations of the pest feed on them. Here a bisexual generation appears, which will return to the currants to lay eggs. This happens closer to autumn.

Ways to combat leaf aphids on currants

An attentive gardener will not miss the appearance of gall aphids on currants; he will immediately take adequate control measures. It is important to notice the deformation of young leaves at the initial stage of the growing season. On them, galls look like small red spots. In addition, the presence of the pest last season - serious reason start preventive measures on the bush as early as possible.

Prevention of infection of berry bushes

In order not to rack your brains about how to get rid of gall aphids, you can try to prevent their appearance. What is recommended to do for this?

In early spring, before the buds open, or in the fall, after leaf fall, spray the bushes and tree trunk area with a solution of nitrafen. The drug is harmful to the leaves (it burns them), so treatment should not be delayed. Its advantage is that it destroys the eggs of wintering pests. For currants, use a 3% solution (30 ml/l of water). To process an adult bush you will need approximately 0.5 liters.
To protect the berry garden from insects from outside, for example, from neighbors, it is recommended to plant it next to berry bush plants with a pungent odor - calendula, marigolds, chamomile.
Destroy weeds in the garden, especially nettle (another name is dead nettle). This perennial weed is an intermediate host for the gall aphid, for which it will thank you.

Advice! One of the options for destroying gall aphid eggs, which can be found in the literature, is scalding the bush with boiling water in the spring. Only one’s own experience can show how effective this is.

Mechanical method

At the initial stage of infection it is recommended mechanical removal shoots with a colony of pests. The bush is carefully inspected, all branches with the slightest deformation of the leaves are cut out. If at least a few individuals remain, they will quickly reproduce again. The cut shoots must be disposed of, preferably burned. This control method gives a good effect when combined with treatment with natural insecticides.

Advice! Along with young growth, the insect is very fond of fatty shoots. At spring pruning First of all, remove the wen from the bush, cut out all the excess shoots.

Spraying with natural insecticides: recipes

Some plants contain large quantities of fungicides, pyrethrins, and other substances that have a destructive effect on gall aphids, so they are widely used to control the pest. To enhance negative impact It is recommended to add soap to infusions, which envelops the insect and blocks its access to oxygen (aphids breathe through the skin). Here are the recipes for several popular infusions.

Based on tobacco dust. To prepare a bucket of infusion you will need 300 g of herbal preparation. It is poured with boiling water and left for 2-3 days. The settled solution is filtered, 100 g of laundry soap dissolved in water is added. Can also be used tar soap or other liquid detergent, for example, for dishes.
Infusion of marigolds. For the infusion, take half a bucket of crushed flowers and fill them with 10 liters hot water and insist for 48 hours. Add 50 g of liquid soap to the finished strained infusion.
Infusion of mustard powder. To prepare 10 liters of working solution you will need 25 g of dry mustard. First, prepare a concentrate - pour mustard powder with a liter of boiling water and leave for 2 days. Then it is brought to full volume, soap is added.

Biochemical method of struggle

When the gall aphid has already multiplied, to combat it you cannot do without chemicals. Considering the toxicity and shelf life of toxic components in plant tissues, it is recommended to spray currants with insecticides at the budding stage, and a second time after harvesting. Spraying with Calypso, Confidor Maxi, Aktelik, Vofatox, Proteus gives a long-term effect.

In addition to chemical insecticides, a modern “herbal pharmacy” offers biological drugs, harmless to humans and domestic animals. They are made from spore bacteria, fungal components, and viruses. Entering the insect's body with food, they affect the intestinal tract, paralyzing and destroying it. Examples of such drugs are Avertin, Actofit, Bitoxibacillin.

Fighting aphids on currants:

Aphids are quite voracious insects that a short time can destroy a lot of plants. In addition to flowers, it also harms berry bushes, for example, currants. However, not everyone knows how to fix this problem. If you have aphids on your currants, our advice will tell you how to fight them.

Before fighting aphids on currants, you should carefully inspect the bushes. If the situation allows, then it is better to cut off the damaged shoots on which the insects are located. In principle, they can also be washed off the leaves with a strong water jet, but in this case the pests may return to their place. Soapy water kills aphids very effectively. To prepare it, it is better to take liquid potash, which has good solubility. As a last resort, you can always use laundry soap. For the mixture you need to take about 30 g of product per 1 liter of water. After spraying, the insects stick together, cannot move and feed, and therefore die.

If you don’t know about currants, you can also make traps for these pests. For example, take a small container and pour soapy water into it. The color is attractive to aphids. Insects willingly climb into the container and drown. If you don’t have time to bother with preparing mixtures, you can place pieces of aluminum foil between the bushes. This way you can prevent the spread of insects.

Before fighting aphids on currants, determine the degree of damage to the bushes. Maybe, mechanical methods fixing the problem will not help. However, there is a large number of various decoctions that will help both destroy pests and protect the bushes from their further appearance. For example, you can prepare a decoction from potato tops. To do this, you will need about 1200 g of green mass to leave in water for several hours. Then the mixture should be filtered and the bushes can be sprayed. Alternatively, you can use dried raw materials.

If you don’t know how to treat currants against aphids, or you don’t have tops, then you can use onion peels. To do this, the scales should be infused in 10 liters of water. For this amount of liquid you should take about 200 g of raw material. A decoction from the plant helps well. To prepare it, you need the green mass of the plant in the amount of 1 kg (the raw materials must be dried). It should be boiled in a small amount of water for about 15 minutes. Then the mixture must be cooled and strained. In addition, the resulting liquid must be diluted with water (10 l) and soap (40 g). It is now ready to use. These are all the answers to the question of how to fight aphids on currants.
