Currant is a berry that grows in many countries. Healthy fruits are tasty and suitable for canning. In the process of growing shrubs, gardeners are faced with insect pests. The size of insects is small, which does not prevent them from forming whole colonies, damaging the bush. Therefore, for summer residents, the question of how to deal with aphids on currants plays a special role.
Varieties of pests
Aphids are small insects that feed on the sap of plants growing in the garden. Summer residents grow a lot of vegetables and fruits, so there are many types of aphids. Some bugs feed exclusively on a particular plant, while others have adapted to attack several types of crops. The appearance of aphids is observed in early spring with the blooming of young leaves.
The body length of the parasite does not exceed 2.5 mm. It is found on white, red and black currants. It is the causative agent of viral infections that enter the plant through insect bites. As a result, abnormal neoplasms are formed on the leaves, which are called galls.
It lays eggs that calmly endure the winter at the base of the buds. The larvae appear in April. Sucking the juice from the buds, they gradually move to green shoots and petioles of newly blossoming leaves.
Winged individuals are found in spring and autumn. Summer is a favorable period for distribution. They look for plants with young shoots, settling on their tops. Gooseberry aphids are parasites on all types of currants.
You can calculate the insect by the shape of the leaves of the plant. They curl up like a cocoon. Aphids use them as protection against bugs. Unfolding the leaf, you can see a large number of aphids along with ants.
After the larvae emerge from the eggs, they populate the lower part of the leaves. In the place of accumulation of insects, the leaves grow and become covered with swellings. Later they take on a reddish tint.
The main signs of damage to the bush
It is very easy to recognize that aphids are eating currants. There are small bugs on the branches, roots of leaves and their lower part. The bushes often have twisted leaves filled with insects inside.
Examining the currants every day, you can notice the appearance of ants climbing the branches.
If there are more affected areas of aphids, the fruits become smaller and fall off, never having time to reach maturity.
Why insects are dangerous for currants
With the first signs of damage to aphid bushes, it is necessary to start fighting. The insect feeds on plant sap, helping to stop the growth of new shoots. Gradually, the infected culture weakens and dies.
In the risk zone, not only red currants, but also other species. The most dangerous are colonies working with black ants. They accelerate plant death by transferring aphids to other parts of the greenery.
What is the connection between ants and aphids?
Ants protect aphids from insect enemies that destroy them. They also transfer aphids to other plants, providing them with food. In turn, the aphids secrete a sticky sweet liquid and leave on the leaves, which the ants feed on. This feature is typical for white, red, green, black and other types of aphids.
Ways to deal with the invasion of aphids and ants
To save the currant bushes from the invasion of aphids, they begin to fight in the spring. Insect control measures are developed depending on the degree of damage to the culture. If aphids are few, traditional medicine will help.
More aggressive methods are used against large infestations of parasites. If an aphid attack has led to the appearance of new colonies, drugs of chemical origin are used. These are fungicides and insecticides.
To prepare solutions that are sprayed on the culture, different products are used. Most are always at hand. Some can be purchased at the pharmacy, as they are freely available. These are drugs that are familiar to everyone from early childhood.
The tool not only helps to defeat aphids on currants, but also saturates the shrubs with nitrogen. There is an acceleration of their growth, the formation of berries and the healing of injuries that were obtained as a result of parasitic aphids. The recipe for baiting is easy to make at home.

Ash allows you to completely get rid of aphids in 4-5 treatments.
Spraying with tobacco-based liquid is carried out three times per season:
- before the buds appear;
- after flowering;
- at the time of ripening of berries.
Tobacco, like ash, can be used undiluted. In order not to prepare solutions, the plant is planted near shrubs. The culture requires constant care, but thanks a person by scaring away aphids and other pests.
Making recipes using simple products involves adding soap. Thanks to it, parts of the plant are covered with a protective film, making it difficult for aphids to feed and hinder movement. For spraying, a soapy solution prepared in water is useful. It can be grated laundry soap or liquid soap.

Another event that does not imply the use of pre-prepared solutions. Affected branches are pruned with a secateurs. Twisted leaves are also torn off. The cut off parts of the bushes are removed from the site and set on fire.
Biologicals and chemicals
It is possible to remove signs of plant damage by aphids with the help of chemicals. But the use is limited to certain periods of the growing season. Insecticides are permitted for spraying in early spring before flowers appear. Poisonous substances that enter the tissues of currants during processing remain in it for up to a month.
Aphids are also removed with biological products. They act much more slowly, but not as aggressive as chemicals. They are based on the waste products of microorganisms, which have the peculiarity of destroying aphids. They do not harm the human body, but are not recommended for use before harvesting.
