Since early spring, summer residents have a lot of worries: watering, weeding and pests are annoying. When the first leaves on the currant bloom, aphids immediately appear. The pest settles on young shoots, which are deformed and dry out. The currant crop is declining. What to do and how to deal with aphids on currants?
How to detect aphids on currants
Most often settles on currants gall aphid- small sucking insect. The aphid feeds on young shoots and currant leaves. You can find a colony of pests on the bottom of a currant leaf. On damaged leaves, red or yellow swellings are formed, tubercles - galls.
Around mid-July, when the currant leaves stop growing, the aphids develop wings. At this point, the pest leaves the bush. If there are a lot of weeds around the plantings, the gall aphid will move to them, where it will feed until autumn. During the season, more than one generation of pests is bred, 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. Weak bushes, affected by a large number of pests, are unable to develop normally. The yield of adult bushes drops sharply, the berry becomes smaller.
How to deal with aphids on currant bushes
One of important factors in the fight against gall aphids on currants, prevention is. From early spring, you need to carry out the main 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, such as ladybugs;
Conduct spring scalding of the bush with boiling water.
Important! If ladybugs and lacewings have settled on currant bushes, then insecticides should be used carefully. It is better to replace them with infusions of herbs. Beneficial insects will help to quickly get rid of aphids.
By attracting beneficial insects to the garden, you can get rid of gall aphids without resorting to chemicals. To attract insects, experienced gardeners practice planting medicinal plants under currant bushes:
Marigold;
Allisum;
yarrow;
Many insects that are useful for the garden prefer to live in plantings of dill or buckwheat.
How to get rid of aphids on currant bushes: garden fumigation
Very often, one of the methods of dealing with aphids is fumigating the garden. Experienced gardeners they practice fumigation with rubber, tobacco and mushrooms.
It is necessary to carry out fumigation before bud break, at the moment of their opening.
Fumigation with rubber is carried out as follows: a piece of rubber is placed in an old pan and put to smolder under each currant bush.
Fumigation with tobacco and mushrooms with a raincoat is carried out with the help of 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 aphid dies completely, there is no need to use chemicals.
The disadvantage of this method is acrid smoke, which adversely affects 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 necessary only in advanced cases and mass attacks of pests.
1. The first spraying of currants is carried out in the spring, at the time of bud break.
2. The second time it is necessary to carry out the processing when the shrub 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 full harvest.
How to treat currants from 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 in the fight against 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, use the following infusions:
Tobacco infusion;
Infusion of marigolds;
Infusion of red hot pepper;
Infusion of tomato tops;
Infusion of onions 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, 500 g of tobacco dust is poured into 10 liters of water and the mixture is infused for several days. The finished infusion is filtered, diluted with 10 liters of water and 100 g of grated laundry soap is added as an adhesive.
Spraying is carried out in the evening, in clear weather. Repeat after rain.
2. Infusion of marigolds
Very effective in the fight against gall aphids is an infusion of marigolds, which is prepared from dried flowers. For a 10 liter bucket, take ½ of the crushed marigolds, which are poured warm water. Infuse the mixture for three days. The finished solution is decanted and 50 g of grated laundry soap is added.
3. Infusion of red hot pepper
You can prepare a concentrated infusion from red capsicum. To do this, 1 kg of fresh pepper must be cut and put in a saucepan, pour 10 liters cold water. Bring the mixture to a boil and simmer for 1 hour. The cooled solution is removed in a warm place for several days. The prepared 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! 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 leaves
From tomato tops, a good infusion is obtained to combat gall aphids on currants. To do this, dry tops of tomatoes, about 2 kg, and fresh tops of 4 kg are crushed by pouring 10 liters of water. The mixture is boiled for 30 minutes. The resulting concentrate is cooled and stored in the cold. 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! The working solution of their tomato leaf concentrate can be used to control ticks, scoops, codling moths, cruciferous flea and gooseberry sawfly.
5. Infusion of onion and garlic
Experienced gardeners advise spraying currants with an infusion of green onion feathers. To do this, 1 kg of chopped green onions is poured into 10 liters of water, the mixture is infused for 6 hours. Strain the prepared solution and spray.
You can use pre-prepared onion peel. For this 500 gr. husks insist in 10 liters of water for about 5 days.
Important! Onion and garlic infusions not only fight pests on currants, but also increase plant immunity.
6. Ash infusion with wormwood
Affected currant bushes are treated with an aphid ash solution with the addition of wormwood. To do this, 500 g of crushed wormwood is poured with water, about 5 liters, adding 1 glass of ash and 50 g 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 of the infusion and 2 parts of water.
7. Soda ash solution
You can treat currants against aphids with a solution of soda. Prepare a working solution of 1 tbsp. l. soda ash and 1 liter of water.
Spraying with such a solution will help get rid of not only aphids, but also drive the fungus out of the bush.
8. Infusion of celandine
Summer residents are fighting aphids with the help of celandine infusion. A solution is prepared from 4 kg of fresh celandine grass, which is crushed and poured with 10 liters of water. You need to insist the solution for a day. Ready solution carry out spraying currant bushes.
Important! When processing plantings of currants with a solution of celandine, it is imperative to use individual protection, since celandine juice is very poisonous.
What to consider when processing currants from gall aphids
Young currant shoots bend well, they can be dipped in any remedy prepared according to recipes and washed well, without the risk of breaking the branch.
You need to spray and wash each branch, without missing a single section of the bush.
You need to spray not only the shrub, but also the soil under it.
The weather during processing should be calm. Keep an eye on the bees when using chemicals. It is important not to poison beneficial insects, which are very necessary in the garden. It is better to transfer spraying to the evening when the bees no longer fly.
When spraying, it is imperative to moisten the lower part of the leaf; for this, the sprayer is directed inside the bush.
Should not be assigned great expectations on the folk ways fighting aphids on currants, if time is lost and the pest has chosen roses, plums and gooseberries. In such a situation, the use of chemicals is indispensable.
In the fight against aphids on currants, it is important to keep the area clean, to prevent a riot of weeds and the neighborhood of shrubs with anthills. Often carry out preventive spraying with infusions of herbs, monitor the density of the bush and cut out diseased branches in time.
Ugly swellings and growths on the leaves of red currant at first glance look like a disease, but it was the gall aphid that worked. Feeding on the juices of the plant, it causes its deformation - traces of vital activity are similar to healed wounds. Worst of all, the voracious and prolific insect prefers young shoots, which means it harms not only current state bush, but also reduces the chances of good harvest in future.

Description of the insect, its harmfulness
The leaf gall aphid is one of the 4 thousand species of the aphid family living 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.
It is red and white currants that act as a food base and host plant for the species, sometimes it can slightly populate black currants. As a facultative (intermediate) plant, she uses herbs of the Lamiaceae (labial) family. In the second half of summer, or if the colony is overcrowded, aphids populate nearby mint, sage, oregano, thyme, lavender, and are very fond of chistets.
In structure and appearance, the gall aphid is similar to its many relatives. small insect egg-shaped 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 fertility that exacerbates its harmfulness. One single founding aphid gives life to tens or even hundreds of thousands of sucking pests. What is the size of the damage from gall aphids that have settled on currants?
- Sucking out the juices, she depletes the shoots. To “heal” wounds, the plant produces special tissues that form growths at the site of damage - galls. If the aphids are not dealt with, they will give birth to new generations and live on the branches until they dry out.
- Attracts other pests, such as ants, to the garden. Not only do they “graze” aphids, protect their entomophages, contribute to its spread, but they themselves feed on the juice of the berries of the same strawberries or grapes.
- Gall aphid can be a carrier of pathogens viral infections plants.
Young shoots affected by aphids, even after the destruction of the pest, lag behind in growth, recover for a long time, therefore, their productivity decreases.
Note! Thunderstorm of aphids - insects-entomophages, in particular ladybugs, lacewings, hoverflies. But if the colony is guarded by ants, they will not let them come close.
"Family" hierarchy of the gall aphid
The life cycle of leaf gall aphids is characterized by such a phenomenon as polyformism. This means that different generations of an insect can differ not only in appearance, but also perform different functions. How does the hierarchy of aphids look like during the growing season and the full cycle of transformation?
- The founding aphid hatches from the egg. She is the "mother" of all generations that will appear during the season. This is a parthenogenetic individual, besides viviparous, that is, 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 the gall aphids that we observe on currants. They do not have wings, so insects are constantly on the host plant, parthenogenetic females give birth to their own kind.
- Settler aphids are a winged generation, they perform a slightly different function. When the colony expands or the food base is depleted, they fly to a new place and establish the next settlement.
- Aphids are a transitional generation of an insect from which females capable of laying eggs and males appear.
- Aphids-females and aphids-males are bisexual generation, which provides wintering of the species. From eggs laid in the bark of currant stalks, aphids-founders appear in spring.
How does a pest develop?
Leaf gall aphids lay their eggs under the bark of red currant branches, closer to the buds. Here it depends on the climatic zone and weather conditions may be up to 9 months. In the spring, as soon as the buds begin to bloom, the founders emerge from the eggs and populate the plant.
Active reproduction of the insect begins from the moment the shrub blooms. The peak of harmfulness falls on June, when the colony reaches its maximum dimensions. In the second half of summer, currant leaves coarsen, aphids begin to settle on intermediate plants. Several more generations of the pest feed on them. A bisexual generation also appears here, which will return to the currant to lay eggs. It happens closer to autumn.
Ways to deal with 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 vegetation. On them, the galls look like small red spots. In addition, the presence of a pest in the past season - serious reason start preventive measures on the bush as early as possible.
Prevention of infection of a berry bush
In order not to rack your brains on how to get rid of gall aphids, you can try to prevent its appearance. What is recommended for this?
- In early spring, before bud break, or in autumn, after leaf fall, spray the bushes and the near-stem area with a solution of nitrafen. The drug is harmful to the leaves (burns them), so the treatment should not be late. Its plus is that it destroys the eggs of wintering pests. For currants, a 3% solution (30 ml / l of water) is used. To process an adult bush, you will need about 0.5 liters.
- In order to protect the berry planter from settling an insect from the 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 the cleaner (the second name is deaf nettle). This perennial weed is an intermediate host of 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. How effective this is, only our own experience can show.
mechanical method
At the initial stage of infection, it is recommended mechanical removal shoots with a colony of pests. The bush is carefully examined, all branches are cut out with the slightest deformation of the leaves. If at least a few individuals remain, they will quickly multiply again. Cut shoots must be disposed of, best of all, burned. This method of struggle gives a good effect in combination with the treatment with natural insecticides.
Advice! Along with young growth, the insect is very fond of fatty shoots. At spring pruning bush, first of all, remove the wen, cut out all the excess zero shoots.
Spraying with natural insecticides: recipes
Some plants contain in large numbers fungicides, pyrethrins, and other substances that have a destructive effect on gall aphids, so they are widely used to control the pest. For amplification negative impact it is recommended to add soap to the infusions, which envelops the insect, blocks its access to oxygen (aphids breathe through the skin). Here is a recipe for several popular infusions.
- Based on tobacco dust. To prepare a bucket of infusion, you need 300 g of a herbal preparation. It is poured with boiling water and insisted for 2-3 days. The settled solution is filtered, 100 g of laundry soap dissolved in water are added. Can also be used tar soap or other liquid detergent, for example, for dishes.
- Infusion of marigolds. For infusion, take half a bucket of crushed flowers, fill them with 10 liters hot water and insist for 48 hours. In the finished strained infusion add 50 g liquid soap.
- Infusion of mustard powder. To prepare 10 liters of working solution, you need 25 g of dry mustard. First, a concentrate is prepared - mustard powder is poured with a liter of boiling water, insisted for 2 days. Then it is brought to full volume, soap is added.
Biochemical way of fighting
When the gall aphid has already bred, it is impossible to do without chemicals. Given the toxicity and retention time of toxic components in plant tissues, it is recommended to spray currants with insecticides at the budding stage, and the second time after harvesting. Spraying with Calypso, Confidor Maxi, Aktelik, Vofatoks, Proteus gives a long-term effect.
In addition to chemical insecticides, the modern "plant pharmacy" offers biological preparations harmless to humans and pets. They are made from spore bacteria, components of fungi, viruses. Getting into the body of an insect with food, they affect the intestinal tract, paralyzing and destroying it. Examples of such drugs are Avertin, Aktofit, Bitoxibacillin.
The fight against aphids on currants:
With the advent of the summer season, every summer resident and gardener is fighting for productivity with various diseases and pests. If currants grow on your site, its most dangerous and frequent enemy is aphids. The presence of aphids on the currant can be spoken of by its appearance- the leaves become convex, as if with red pimples. Currant shoots infected with aphids become painful and stunted.
How aphids harm currants
Aphids are small insects 1-2 mm in size, which can be green, gray and white color. Aphid females lay eggs for the winter, and with the advent of warm days, insects come to life. The aphid feeds on the juice of the fruits and leaves of the plant, piercing juicy greens with its proboscis. The aphid colonies are numerous, so they quickly suck out all the life-giving forces from the currant, leaving the bush to wither. Without life-giving juice, currants cannot resist foreign diseases; they often die.
The life cycle of aphids is small, more than a dozen generations change over the summer. The female lays a huge number of eggs, and without fertilization, and only females are born. Over time, when the aphid completely eats the plant, winged forms of insects may appear that easily infect neighboring shrubs. And only in autumn males are born in the colony. The fertilized female lays eggs that can survive the harsh winter.
Aphids and ants
Separately, I would like to say a few words about ants. Some mistakenly believe that ants fight aphids. But it's not. Aphids produce sweet dew, which ants love to feast on. Therefore, they protect and protect their "breadwinners" in every possible way. If the currant is infested with aphids, you can observe a huge number of ants near the bush. Ants deliberately tickle the abdomen of aphids with their antennae to get some sweet treats. Not only that, the ants carry aphids to uninfected shrubs so that the insect produces more of its favorite treat. Therefore, in the fight against aphids, it is very important to destroy ants as the main "accomplices" of these pests.
How to deal with aphids professionally
There are many professional tools fight against aphids that do not harm currants. Among them are the following insecticides.
- Kinmix
- Karbofos
- Aktara
- Rovikurt
- Vofatoks
The plant is sprayed three times. The first time before the appearance of the kidneys. The second time - after the appearance of the first leaves. And the third time - at the end of the season, but at least a month before the start of the harvest. The insecticide is diluted according to the instructions, usually the dose is a tablespoon per 10 liters of water. Thoroughly need to spray the roots and stems of the shrub, its leaves on the reverse side.
Do not forget to simultaneously fight the ants. If there is an anthill near the infected shrub, you need to pour boiling water over it. This will kill the insects but not damage the branches and roots of the plant.
But professional insecticides are not always at hand. Then you can use folk recipes.
The very first and most important thing you should do when you find "painful" leaves is to pick them up and burn them. Collect all the convex and twisted leaves - a colony of insects is concentrated on them.
- Tobacco and ash. Take the usual shag, which is used in the manufacture of cigarettes. Half a kilo of tobacco must be mixed with the same amount of ash and diluted with ten liters of water. Treat the diseased bush with the prepared remedy.
- Ash and soap. Dissolve 200 grams of ash in 10-15 liters of water. Add a glass of cheap liquid soap. If liquid soap is not at hand, you can grate ordinary laundry soap and dissolve in the total mass.
- Soda ash. A solution of soda ash perfectly fights aphids and other pests. Dissolve the powder at the rate of one tablespoon per liter of water. For greater effect, you can add a little soap to the mass.
- Celandine. Among natural remedies the fight against aphids can be noted celandine. Celandine bushes are torn off and filled with water. For 10 liters of water, you need to take a couple of kilograms of fresh green grass. Insist medicinal herb it takes about a day, after which the infusion is filtered and sprayed under a bush with a spray bottle. Before processing, be sure to wear gloves, as the celandine is quite poisonous.
- Onion. It is very effective in controlling aphids and other pests. To prepare a healing infusion, you need to grind onion or green onion, pour it with water and let the mass brew for 4-5 days. After that, the bushes affected by aphids are watered with the prepared remedy. Usually, after a couple of such treatments, there is no trace of pests left.
- Ladybugs. These insects contribute to the extermination of aphids, so you need to attract ladybugs to your site in every possible way. To do this, near the currant bushes, you need to plant calendula, tansy, mallow, nasturtium. The smell of these flowers attracts ladybugs and they are happy to settle on your site.
- Tops of tomatoes. After picking tomatoes, do not rush to throw out the tops. She fights aphids very well. The tops are crushed, placed in a large vat and filled with water. After a couple of days, the "medicine" is ready. They are watered with diseased bushes so as to cover the largest possible area of \u200b\u200bthe earth at the roots, stems.
- Quinoa. In the fight against insidious aphids, you need to use all means and be smarter. Do not remove all the weeds under the currant bush. If you have not dealt with aphids yet, leave a little quinoa under the bush - aphids love it very much. So you can at least protect a little and take pests away from currants.
If you find aphids - do not rush to give up. This pest can and should be fought, otherwise the aphid will spoil your crop from year to year. Do not give up trying to get rid of aphids in order to collect sweet and delicious fruits currants.

Aphids can cause irreparable harm to the plant
Regardless of food preferences, all aphids are phytophages, capable of piercing the epidermis of leaf blades and young shoots and sucking juices rich in carbohydrates and amino acids from the mesophyll. The end product of the digestion of aphids is honeydew, a sweet liquid that is very attractive to ants.
Adult aphids of any species, depending on the time of their birth, can take the form of wingless females (having eggs at the beginning of the growing season) or winged males and females (born in mid and late summer).
Symptoms of damage to currant aphids
Bushes of red and white currants are affected by red-gall and hairy currant aphids, as evidenced by specific orange or red blistering swellings on leaf plates and the skin of young shoots.
Red bumps on leaves and stems are a sign of aphids.
Gooseberry aphids “eat” blackcurrant, the presence of which can be judged by:
- upper leaves curled into a ball;
- twisted and drooping young shoots.
Prevention of aphid infestation
To prevent infection of a currant plantation with aphids, you should:
1. In autumn and again in early spring sanitary pruning of suspicious and old shoots.
Attention! All branches removed from the bushes must be immediately collected in a bag, taken out of the site and burned.
2. Before the plants begin to grow and the buds come to life on them, scald the currant bushes with boiling water from a watering can with a shower head.
Damaged aphids branches and leaves must be removed
Advice. To prevent ants from crawling onto currant bushes, wrap the trunks of the lower branches of plants with double-sided sticky tape or coat them with special, long-lasting garden glue.
4. Plant the berry with marigolds, sage, mint, garlic, coriander, calendula, lavender or dill, the smell of which repels aphids.
5. At the stage of bud swelling, fumigate currant bushes with smoke from smoldering worthless tires, raincoat mushrooms or self-garden tobacco.
The fumigation procedure should be carried out for 3-4 hours, in the evening, in calm weather. Pieces of old tires can simply be placed in tins, rubber set on fire and smoky braziers placed between rows of currant bushes, for fumigating with mushrooms or tobacco you will need a bee smoker.

Folk methods of dealing with aphids on currants
Industrial pesticides can solve the problem with aphids in a fundamental way, but the crop obtained after their use can no longer be called environmentally friendly. Therefore, before using such “heavy artillery”, try to get by with mildly acting herbal decoctions and infusions, the main advantage of which is their safety for environment and human health.
- Cut into large pieces 1 kg of fresh hot pepper and fill it with a bucket of spring water. Boil the "hellish" spicy mixture and boil it over minimal heat for one hour. Leave the pepper broth to infuse under the lid in a warm place, after 2 days strain it through a strainer, pour the tincture into a bottle and put it in the refrigerator for storage. When it becomes necessary to process currants, dilute 1 cup of burning concentrate in a bucket of settled water, add a handful of soap chips to the solution for better adhesion, and spray damaged aphids with the resulting preparation.
- Pick up a large armful of celandine. In order not to stain your palms with poisonous yellow juice that is difficult to wash off, put on rubber gloves and cut the grass with a cleaver. Half fill the bucket with chopped celandine, fill the grass with water and let the mixture brew for 18-20 hours. After the specified time, strain the tincture, bring its volume to 10 liters and spray the affected currant bushes with the resulting working solution.
- Pour a liter jar of finely chopped fresh wormwood into a bucket and fill it halfway with water. Add to the herbal gruel 2 cups of crushed wood ash and a quarter of a bar of gray laundry soap (cut with a knife or chopped on a grater). Stir the preparation with a stick, after 6 hours strain the liquid, and prepare a working solution consisting of 1 part of the resulting tincture and 2 parts of settled, slightly warmed water.
Before using chemicals against aphids, you can try folk
General rules for processing currants
Regardless of which herbal remedy you have chosen for spraying, currant treatment should be carried out:
- in calm weather;
- late morning or early evening;
- at least 4 times per season, and even better weekly, and repeat it after every heavy rain.
In addition, before spraying it is necessary:
- inspect the bushes, cut and burn badly damaged shoots;
- bend down and completely dip the tops of young twigs into a bucket with a working solution;
- hand wash the back sides of slightly damaged large leaves.
It is necessary to spray the currants evenly, inserting the nozzle of the sprayer deep into the bushes and directing it in all directions (including from the bottom up).
"Aktara" against aphids
Chemical preparations for aphid control
In case of severe damage to aphids, currant bushes can be processed industrial insecticides, the best of which are:
- "Vofatoks";
- "Aktara";
- "Aktellik";
- "Ratibor";
- "Rovikurt";
- "Confidor";
- "Decis".
"Aktellik" against aphids
All of the above drugs are diluted in water in accordance with the manufacturer's instructions and used no more than 3 times per season, namely:
- before bud break;
- in the phase of leaf formation;
- at the end of flowering, but not later than one month before harvest.
It is not so difficult to ensure that the currant bears abundant fruit and is not affected by aphids. To do this, you need to carefully care for the bushes, carefully monitor the condition of the plants and carry out their protective treatment in a timely manner.

Currant is not only delicious, but also incredibly useful berry. It contains many vitamins, so necessary for normal operation organism. But in order to get a rich harvest, you need to be patient and take a responsible approach to caring for berry bushes.
Preparations
The first time to process currants is necessary after the buds have blossomed. The second time processing is needed a month before the appearance of the crop.
The following drugs remain effective against aphids:
Of the chemicals, the most effective are the following:
In order for the poison to have the maximum effect, it is necessary to strictly adhere to the instructions that are in the package with the drug.
Folk remedies
In the assortment of non-traditional composition against aphids, there are a lot of recipes. Each of them is effective in its own way, so let's consider each separately.
