Treatment of currants from aphids with garlic infusion. Aphids on currants - what to do

cultivation fruit bushes- an exciting activity, but also quite troublesome, because for almost every berry you have to fight against the ubiquitous pests. Chemicals will help preserve the crop, but if, at the first sign of an undesirable neighborhood, you enter into a ruthless duel, it is quite possible to get by with simple folk remedies. What emergency measures should be taken if aphids settled on currants, how to deal with pests, and, most importantly, how to recognize the danger in time?

How to detect aphids on currant bushes

It is quite difficult for inexperienced beginners to recognize pests on currant bushes, because insects are in no hurry to find their location, hiding between leaves, in internodes and even on fruits. Currants should be carefully examined throughout the warm season, but in late May and early summer, especially carefully - it is at this time that the aphid is active and tries to settle in new territories.

The main sign of aphids is a large cluster of ant families near currants. Novice gardeners believe that ants eat pests, and diligently protect the black "helpers". Do not be mistaken and make a gross mistake - the ants feed on the sweet juice secreted by aphids, and diligently look after their "herd". Looking closely at the life of insects on the currant, you can see that the ants even help the aphids to move to healthy succulent shoots. Before getting rid of aphids, it would be useful to drive voluntary "guards" from the site.

In addition to the accumulation of ants near currant bushes, there are several more signs of aphids appearing on plants:

• reddish swellings on the leaves (usually white or red currant);
• rolled leaves (blackcurrant);
• sticky liquid on branches and leaves;
• young shoots stop growing and developing.

Having found the right signs of the appearance of pests, you must immediately take up their destruction using proven means.

Basic rules for dealing with aphids by simple means

Before you fight aphids with folk remedies, you need to familiarize yourself with a few simple requirements, strict adherence to which will certainly lead to an excellent result.

Basic rules for the use of self-prepared compositions:

1. It is better to go to fight against aphids in the evening hours - some mixtures under the influence of sunlight can lose their properties or harm currants.
2. Despite the safety of most folk remedies, it is better to protect your hands with gloves and your face with a mask.
3. You should not experiment with compositions and add your own components - in the absence of experience, you can easily destroy the bushes.
4. The weather must be calm and dry - gusts of wind will complicate processing, and rain will simply wash away the mixture that is harmful to aphids.

Summer is a period when you will not envy summer residents. And all the work on the site must be carried out in a short time so that the harvest is good, and do not miss watering, and do not forget to thin out the plants. And then there are various pests that annoy. Among them are aphids, which attack currant bushes in summer. If the plant has not faded yet, then they will help chemicals. However, most often this pest makes itself felt during the appearance of the first green berries. How to be and what means can be used to save the harvest of such tasty, fragrant and healthy berries?

Preventive measures

It is better, of course, to start the main processing of currant bushes at a time when the first green tips appear on them in the spring. Various preparations for aphids on currants ("Fitoverm", "Commander", "Aktelik", etc.) are not a problem to find today. They are offered in a wide range in any specialized stores. But do not think that one treatment of currants from aphids will be effective. Spraying will need to be repeated when the first buds appear. Two more treatments should be done immediately before flowering and immediately after it. It should be noted that after the first two sprayings green aphid on the currant it will practically disappear, and the third treatment will scare away the moth, the caterpillars of which wrap the berries in a thick cobweb. Fourth spray - preventive measure control of aphids and other pests on currants.

It is worth noting that the gall aphid on the currant is a consequence of the appearance of ants on the currant. The appearance of these insects should immediately alert you, because ants use aphids as so-called cows. Helping pests to settle on the plant, they feed on honeydew - a sweetish liquid that aphids secrete after they suck the juice from currant leaves. If you destroy the ants, then the aphids will leave the currant bushes alone. Fill all ant trails with an ash solution or an infusion of water with hot pepper.

Folk remedies

And how to spray currants from aphids, if time is lost, and the leaves on the tops of the bushes are already twisted? Summer residents have long been familiar with folk remedies that help get rid of pests. So, how to destroy aphids on currants and save the crop. Below are the methods to help solve the problem.

Currant bushes that are attacked by aphids are best treated in the afternoon three times a week. Folk methods do not give such a result as chemicals, but also harmful substances berries will not. If after processing the aphid has not disappeared, do not stop fighting it - the result will be, but later.

It is also worth planting spicy plants under currant bushes. Aromas of parsley, coriander, dill, parsnip, sage and these pests repel. But the neighborhood with corn beds is dangerous for currants, since the aphid loves it very much.

The aphid family is very extensive. The number of its representatives reaches 4 thousand. On currant bushes with red and white berries, leaf gall aphids most often settle. As a result of the activity of the pest, the leaves of the plant are covered with swellings and growths of yellowish and cherry color. They may also appear on its branches. Blackcurrants are more attracted to gooseberry shoot aphids. eating cell sap, tiny insects cause twisting and wilting of leaves, deformation of buds. Young shoots of currant bushes inhabited by pests are bent, and their growth is slowing down.

But leaf and other types of aphids are dangerous not only for this. A large colony of insects weakens the plant, making it vulnerable to viruses and bacteria. The logical result of their appearance in the garden - dangerous diseases. Unable to process all the juice they suck out, pests secrete a sweet substance (honeydew, or honeydew). The sticky film on the plant prevents it from breathing, besides, they quickly settle in it and actively develop different kind fungi. It is because of aphids that white and red currants begin to suffer from black sooty dew.

Contrary to a common misconception, ants do not fight pests, but contribute to their settlement, transferring slow and clumsy wingless insects to shoots that have not yet been colonized by them. The reason for this is the same fall. Ants love to feast on sugary substance. The appearance of hordes of these insects on the branches of currants is a reason to sound the alarm. Measures to combat aphids necessarily include the destruction of anthills located near infected plants.

Gentle methods of struggle

You can get rid of pests on currant bushes different ways. When choosing a remedy, it is necessary to take into account first of all the degree of damage. If there are few plants affected by aphids, and a colony of insects has not yet grown on them, they will come to the rescue folk recipes. The infusions made according to them are safe for humans and animals, and they can be made from improvised means.

• wood ash. 3 liters are added to 2 glasses of the substance hot water and dissolve in the resulting mixture 1 tbsp. l soap (liquid or laundry is suitable). You can spray currants with the resulting composition in a day, after filtering it. Ash will perform 2 functions at once: it will scare away aphids and provide plants with nutrients.
• Liquid soap (you can use any dishwashing detergent instead). 2 tbsp. l of a viscous substance is dissolved in 1 glass of water. The composition is used immediately after preparation. To destroy pests, currants are sprayed with them daily. The agent acts on the respiratory organs of aphids, clogging them and causing the death of insects.
• Tobacco dust (shag). Pouring 1 liter of water into a container, add 100 g of dry mass to it. The mixture is put on the stove, brought to a boil and kept on low heat for 1 hour. The cooled agent is filtered and diluted with water, adding 300 ml of tobacco infusion to a bucket of water. It is better to spray currants from a spray bottle. Re-treatment is carried out after 2 days. To enhance the effect, you can mix tobacco with wood ash. For 10 liters of water, take 400 g of each substance.
• Soda ash. To prepare an aphid remedy, the drug is dissolved in water (1 tablespoon of the substance per 1 liter), adding a little soap to it.

The treatment of currants with herbal infusions brings good results. Some common plants repel aphids.

• Celandine. Its tops can be used fresh (3-4 kg) or dried (1 kg). Filling the grass with 10 liters of water, it is left for 24-30 hours. Use after straining.
• Dandelion. Its roots (200 g) or leaves (400 g) will help get rid of insects. 10 l is added to a container with vegetable raw materials. warm water. It will be possible to treat the bushes affected by aphids with dandelion infusion in 2 hours.
• Onion. Insects are repelled by the smell of its husk. An infusion is prepared from it for 4-5 days. For 10 liters of water take 200 g of husk. Green feathers will also come in handy. A means for spraying currants is prepared from them in the same way, but the volume of vegetable raw materials is increased to 3-4 kg.
• Hot pepper. After grinding its pods, they are poured with water (1:10) and, after boiling for 30 minutes, left for 2 days. Then the composition is filtered. Before treating them with currants, the infusion is diluted (100 ml per 1 liter clean water). An aphid repellent can be prepared from orange or lemon peels, wormwood, tansy, yarrow. The same recipe is used, but with one difference: it is not necessary to dilute the resulting composition.
• Potato tops. Finely chopped it and pouring boiling water (the proportions should be the same), let the mixture brew. After 2 days, it is filtered and the currants are sprayed with it. In the same way, an infusion of marigolds and tomatoes is prepared.

To save the garden from aphids, you have to try. Insects live on the lower part of the leaves, so currants should be sprayed so that poisonous compounds fall on it. The use of a spray gun will increase the effectiveness of the procedure. Do not forget about safety rules. A mask on the face and rubber gloves on the hands will protect the skin and respiratory organs from harmful substances.

To prevent infection and fight it, professionals fumigate black and red currants with dry celandine stems. Repel aphids and tobacco-ash mixture. She powdered the lower part of the leaves. It is recommended to do this when high humidity(after rain or watering). Ash is also sprinkled under the bushes from spring to autumn.

Biological and mechanical methods

In the early stages of infection, as well as after flowering, when berries have already set and it has become dangerous to use chemicals, experienced gardeners prefer to fight against aphids on currants mechanically removing pests from plants. For this

• Carefully cut off and burn damaged (twisted or swollen) leaves and tops of shoots.
• Wash off insects with water by directing a hose under strong pressure at the bush.
• Press aphids on the plant with rubber-gloved hands.
• In the spring, cut off and destroy infected buds. This must be done before they have blossomed yet. The buds in which the eggs of pests overwintered in autumn differ from healthy ones in their larger size and rounded shape.

Despite the effectiveness of these measures, they have a significant drawback - the complexity and the need for repeated treatments. Using them, you will have to carefully examine the blackcurrant every day. When young insects hatch from the eggs, the fight against aphids will begin anew.

To protect plantings from pests, summer residents attract their natural enemies to their plots. The aphids have a lot of them, they exterminate it:

• small birds;
• ladybugs;
• lacewings;
• earwigs;
• hoverflies.

To lure tits and sparrows will help the installation of drinkers and feeders. If you break a bed with tomatoes and dill or a flower garden with marigolds, calendula, nasturtium, cosmea next to currants, their smell will simultaneously repel aphids and attract beetles that eat it. A bad neighbor for a shrub is corn. Pests love its succulent leaves. After destroying corn plantations, they will attack blackcurrants.

Insects hunting for aphids can be planted artificially on plants. They are sold in stores specializing in organic farming or agricultural markets.

Useful in the fight against aphids and weeds. Insects love swan. If you leave a few plants under the currant bushes, they will take the hit. After the aphids have settled, the quinoa is pulled out and burned.

chemical attack

With a large area of ​​\u200b\u200bdamage, it is more advisable to use special aphid preparations.

You can treat currants with insecticides:

• "Aktara";
• "Wofatox";
• "Inta-Virom";
• "Kinmiks";
• "Confidor";
• "Karbofos";
• "Rovikurt";
• "Fufanon";
• Fury.

Due to the high toxicity of these products, they should be handled with a protective mask and rubber gloves. To achieve a sustainable result, 3 treatments are carried out:

1. before bud break;
2. after the appearance of young leaves;
3. in summer (at least a month before the berries ripen).

The fight against aphids with chemicals can be safe only if the manufacturer's recommendations are strictly followed. It is necessary to take into account the duration of the action of the remedy. If the waiting period is more than 2 weeks, it is no longer possible to use it against aphids on currants at the budding stage. In this case, it is better to use preparations of biological origin ("Fitoverm").

Chemicals are a salvation for summer residents whose plots are attacked annually by aphids. Having processed blackcurrants with them at the beginning growing season and after another 2 weeks (the exact dates are written in the instructions), you can forget about pests. Since the aphid is able to develop immunity to the poisons used against it, the preparations must be changed. Better to do it annually.

Infection prevention

The appearance and rapid spread of aphids is a reason to think about whether currant care is carried out correctly. Strong and healthy plants are resistant to pests. The short proboscis of aphids is unable to break through their tough leaves, so insects do not settle on them, preferring to look for easier prey.

Prevention of aphids on currants comes down to the following activities.

• Timely watering and fertilizing bushes with low nitrogen compounds.
• Annual pruning, involving the removal of old, dry, diseased, damaged, extra branches and root shoots;
• Mulch soil under plants.
• Weed removal.
• Cleaning the trunk of exfoliated bark, in which aphid eggs can hibernate.
• Extermination of ants living under a bush or next to it. Here, ordinary boiling water will help. Having filled a bucket with it, it is poured onto an anthill. Doing this is recommended in early spring. A shallow trench dug around a currant bush and filled with a sticky substance will limit the movement of ants.

Aphids do not like strongly smelling plants: mint, garlic, onions, parsley, coriander, basil. If you plant them next to currants, you can not be afraid of insect invasions.

In autumn, the soil under the plants is slightly loosened, and with the advent of spring, their trunks are whitened. For prevention purposes, you can treat bushes with systemic insecticides that have not yet awakened buds, and spill the ground under them with the rest of the solution. This will enhance plant protection.

It will take time and patience to get rid of the aphid currants that have settled on the bushes. The best results in this difficult matter are achieved by summer residents who use an integrated approach. Proper agricultural practices, implementation of preventive measures, attraction of natural enemies of insects, planting around the berry useful plants will protect currant bushes from infection. If it was not possible to avoid it, early stages you can get by with more environmentally friendly physical, biological and folk methods destruction of the enemy. With their insufficient effectiveness, they switch to heavy artillery - preparations with an insecticidal effect.

The appearance on the leaves of white or red currant of blisters-galls of a reddish color, and on black - leaves rolled into a tube indicates that they have wound up in the berry dangerous pests. It is hosted by aphids on currants. On red and white, red-gall and currant hairy usually settle, and on black - gooseberry shoot aphid. At favorable conditions(dry, hot weather) pest colonies grow rapidly and can cause significant damage to plants and significantly reduce the yield of berries. Therefore, it is necessary to fight aphids on currants throughout the summer.

Briefly about the pest

The life cycle of aphids is very short, up to 10 generations can change in one summer. Young insects appear on plants in the spring from overwintered eggs, at the time of blooming of young leaves. The pest multiplies rapidly. Females bring offspring without fertilization (parthenogenesis), and only females are born. When the colony on the currant grows strong enough, and the affected shoots and leaves begin to wither, not providing the pests with enough food, then winged forms of aphids begin to appear en masse, which easily fly to healthy shoots and neighboring bushes. With the onset of autumn, males begin to be born. During sexual reproduction, females lay eggs on shoots near the buds, which will remain overwintering.

Digesting the juice sucked from the plant, aphids release sweet droplets - honeydew, or honeydew - that attract other insects, especially ants. Usually, many ants scurry up and down the branches if the currant is affected by this pest. They not only do not eat aphids (as some people think), but rather carefully protect it, transfer it to intact shoots. Ants watch over, cherish and even “milk” (tickling their belly antennae) “herds” of their “cows” for the sake of drops of a sweet span. It should be noted that aphids always respond to "milking", highlighting a sweet drop for their guards. Therefore, if you are going to deal with aphids on currants, you should first get rid of the anthills located nearby.

Fighting methods

If currant bushes are slightly affected by aphids and the number of bushes is small, then you can try to get rid of the pest without using pesticides. In large plantations, the fight is carried out with chemical preparations. When spraying, it should be borne in mind that the aphid colony is located on the underside of the leaves, so it is necessary to ensure that the solution gets to the places where the pests are concentrated.

• If leaves with reddish swellings (galls) are found on the berries, they must be cut off and destroyed (better - burn). You should also deal with lumps of twisted leaves at the ends of the shoots.
• You can effectively fight aphids with the help of an infusion prepared from a mixture of tobacco (shag) and wood ash(400 g per 10 liters of water).
• For spraying against aphids, you can use a solution of soda ash at the rate of 1 tbsp. spoon for 1 liter of water. Add soap to the solution.
• Many gardeners fight aphids with infusion of celandine. For 10 liters of water, about 3.5 kg of fresh grass is taken and infused for a day, then the affected bushes are sprayed. During processing, use personal protection, since the juice of celandine is poisonous.
• You can fight the aphid invasion with an infusion of onion feathers (3-4 kg) or onion peel(200 g), which are kept in 10 liters of water for 3-4 days (finely chopped heads can be used).
• You can get rid of aphids with ordinary wood ash. 200 - 250 grams should be poured with boiling water and left to cool. Soap should be added to the filtered solution (you can use inexpensive liquid soap), bring the volume up to 10 liters.
• On significant currant plantations, the fight against aphids is carried out with chemical preparations. The following insecticides can be effectively used for these purposes: Vofatoks, Kinmiks, Karbofos, Aktara, Rovikurt and others. Spraying is carried out before bud break, again - immediately after the appearance of leaves and a third time in summer, but no later than 30 days before harvest.

It should be noted that planting plants that repel aphids next to the currant reduces the damage to the bushes by pests. These plants include: onions, tomatoes, dill, garlic, parsley, mint, basil, coriander, tansy, marigolds, yarrow. The use of a set of measures allows you to almost completely get rid of aphids in the garden.

Garden plots of Belarus, Russia, Ukraine abound with currant bushes. Weight useful substances contained in the fruits of this shrub, brought him great popularity. Currant fruits have healing properties, are widely used in traditional medicine. However, currants are loved not only by people, but also by pests, the main of which is aphids. How to get rid of aphids on currants? What are the methods of dealing with aphids, you can find out by reading this article.

It is very easy to notice the presence of aphids on currants. Having carefully looked at the bush and noticed ants scurrying everywhere on it, we can safely assume that there is an aphid colony here.

After all, aphids and ants are one. Ants feed on the honeydew secreted by aphids during their digestion. By itself, the aphid is clumsy and slow, so the ants carry it on themselves to the most delicious parts of the plant. Therefore, to start the fight against aphids, you need to destroy the ants. Carefully examining the surroundings near the bush in search of an anthill, you can definitely find it near the currant, or even in its roots. Now it remains to pour a bucket of boiling water into the anthill in early spring. The ants will die at the same time, and then you can already begin to destroy the aphids.

Aphids are inside unopened buds, which appearance easy to determine. Buds with aphids inside are larger and have a rounded shape. All such kidneys are collected and burned.

How to get rid of aphids on currant leaves?

Often, red bulges can be seen on the leaves. The leaves are swollen and have a very unhealthy appearance. This means that the leaves were struck by the red-gall aphid. The eggs laid by her hibernate on the branches of the bush, and with the onset of spring, the larvae emerge from them and settle on the reverse side of young currant leaves. In places of accumulation of aphids, the leaves swell and acquire a reddish tint.

Blackcurrant leaves are more often affected by gooseberry shoot aphids. She appears on the tops of the shoots, sucks the juice out of them, the leaves curl and bend.

Measures to combat aphids on currants

You need to immediately understand for yourself that it is impossible to get rid of aphids forever. But it is necessary to correctly build and apply a line of defense.

There are two ways to deal with aphids, namely:

1. organic;
2. chemical.

The organic method of aphids includes a variety of methods associated with natural remedies, without the use of pesticides. Such methods are particularly effective for the prevention of disease or in the early stages of infestation of an aphid plant.

To prevent the spread of aphids, excess shoots are cut out, tops in which aphids freely reproduce. Next, you should regularly water, feed and mulch the plant. On a healthy bush with hard dark leaves, aphids will feel uncomfortable. It is imperative to clean the bark in the places of its exfoliation, where aphids oviposited overwintered, which contributes to its significant reduction.

We must not forget about the natural predators of aphids - ladybugs. To attract these beneficial insects you need to plant nasturtium, tansy, mallow, cosmea, calendula near the currant. The aromas of these flowers attract ladybugs and encourage their reproduction.

There is no need to rush to remove all the weeds under the currant bushes. It is advisable to leave one or two bushes of quinoa, which is a delicacy for aphids. The affected quinoa bush can be easily pulled out and destroyed when it has fulfilled its function, taking fire upon itself.

Chemical methods are used when natural remedies no longer help or when time is limited.

Chemical preparations for combating aphids are:

• contact;
• intestinal;
• systemic.

Contact preparations "Fufan", "Fury", "Karbafos" instantly rid the plant of aphids, as penetrating through its cover, they immediately kill it.

Intestinal enter the digestive system during the absorption of leaves treated with chemicals "Confidor", "BI-58 New".

The action of systemic drugs is extended in time for 15-20 days. Processing a bush with such preparations makes the juice poisonous for a very long time. Such a drug may be Aktara.
