How to process currants in the fall: popular fungicides, insecticides, complex preparations and tank mixtures

The currant has many enemies: kidney and spider mites, fire flies, aphids, glass, powdery mildew fungi. It is difficult to deal with them, since the culture blooms in early spring, and in summer it pours berries. Therefore, it is better to carry out treatments for all misfortunes in the fall. And there are very different and effective drugs for this.

Goals and terms of processing currants in the fall

During the season, a large number of pathogenic fungi accumulate on currant leaves, shoots, buds, and in the ground. In the same places, insects lay eggs and hide for the winter. Without autumn processing, fungi and pests will overwinter, wake up in the spring, begin to feed on young leaves and juices from them; multiply, multiplying their numbers and destructive effects on currants.

There are two favorable periods for processing currants at the end of the season:

  1. In early autumn, when the air temperature still rises above +15 ... +20 ° C. Many drugs are most effective in warm weather, especially biological ones.
  2. In late autumn, when the shoots are no longer growing, the bark has become woody, the air temperature is kept below +10 ° C for a long time, the leaves may still remain green, but they have already become coarse and dark. All this speaks of the termination of the development of the above-ground part. It is not necessary to wait for leaf fall, you can start eradicating treatments with chemical and highly concentrated preparations, sparing no foliage. Moreover, in many regions, frosts and snow come before it has time to crumble.

Decide which period is more favorable for you and buy drugs with the appropriate application temperature. If you could not or did not have time to process the currants in the fall, you can postpone this event until early spring, before budding, the deadline is along a green cone. Later, the pests will settle in all the bushes, the period of flowering and fruiting will begin, it will be difficult to fight.

Review of means for processing currants

Many different products are produced today, but they all lend themselves to classification:

  • fungicides - for diseases;
  • insecticides - from insects;
  • acaricides - from ticks;
  • complex impact:
    • insectoacaricides - against insects and ticks;
    • 2 in 1 - from diseases and ticks or from diseases and insects;
    • 3 in 1 - against diseases, ticks and insects.

Within each group, both chemically synthesized drugs and biological ones can be found.

Chemical and biological fungicides

Of the chemical fungicides, Bordeaux liquid is the most popular. In early autumn, a 1% solution is needed, and in late autumn, a 3% solution. This is a drug of contact action, that is, it kills fungi if they come into direct contact with them. This means that it is necessary to spray very carefully, wetting all surfaces of leaves, shoots and the ground under the bush.

You no longer need to mix powders, you can buy ready-made Bordeaux liquid and dilute

There is a similar preparation, also containing copper - HOM. The solution is prepared from 40 g of powder and 10 liters of water. It is necessary to spray thoroughly, as well as with a Bordeaux mixture. In the fall, one treatment with HOM or Bordeaux liquid will be enough.

HOM - similar to Bordeaux liquid

Another chemical often uses urea. The fertilizer known to all has fungicidal properties and is especially effective against the main enemy of any currant - powdery mildew. They are treated with urea in late autumn. A highly concentrated solution is prepared: 700 g (about 2 half-liter cans of granules) per 10 liters of water. Spray well the bush and the ground under it. All fungi, larvae, insects die from burns. If leaves still remain on the branches, they will turn yellow, crumble and quickly decompose together with the parasites that lived on it.

Highly concentrated urea solution has fungicidal properties

Chemical fungicides used in late autumn, if the instructions are followed, are low-toxic, since the foliage no longer absorbs substances, they do not enter the plant, they do not accumulate, they cannot poison us.

Biofungicides (Fitosporin, Trichoderma, Alirin, Glyokladin, Gamair) on currants are ineffective in any season, since most of these are soil fungi and bacteria, they do not live on leaves and shoots. They can shed earth under the bushes, but only for prevention, strengthening the immunity of currants and improving the soil. For the vital activity of beneficial fungi, conditions are necessary:

  • soil temperature from +4 ° C;
  • high humidity;
  • nutrient soil with organic matter;
  • acidic soil reaction: pH 4–6.

Chemical and biological preparations for pests

In the fall, it is better not to waste time on insecticides and acaricides, there are insectoacaricides that allow you to destroy both insects and ticks in one spraying:

  • Karbofos - 60 g / 10 l of water;
  • Actellik - 2 ml / 2 l;
  • Fufanon - 5 ml / 5 l;
  • Karate Zeon - 5 ml / 10 l.

The drugs are most effective in the temperature range: +15 ... +25 ° C. If the pest infestation was strong and it is still warm, then after 10-14 days it is necessary to repeat the treatment. The listed chemicals in large doses are toxic to humans, animals, all insects and ticks, including beneficial ones.

For opponents of chemistry, biologics are produced:

  • Neem oil - migrated from natural cosmetics to bioinsecticides. Neem is an evergreen tree native to India. For spraying, 30 ml of oil is dissolved in 3 liters of water and 1 tbsp. l. green soap. The solution forms an airtight film, under which insects and larvae suffocate. The treatments are repeated every 3-5 days.

    New-fashioned biological product from the Indian tree Neem

  • Avermectins - a group of bioinsectoacaricides containing waste products of microorganisms. They are detrimental to ticks and insects. Most Popular:
    • Fitoverm - 2 ml / l, application temperature - from +20 ° C;
    • Aktofit - 6 ml / l, works at +18 ° C and above.
  • Bitoxibacillin - bioinsecticide, contains microbes that get inside insects feeding on leaves and cause their death. For spraying currants in 10 liters of water, it is necessary to dilute 80-100 g of the preparation.

Biologicals from the last two points are suitable for early autumn, since they act only on feeding parasites, and at the end of the season, due to the coolness, they are already inactive. It is necessary to process the leaves, three times or more with an interval of 5-7 days.

Complex action means

There are means that allow one treatment to simultaneously get rid of diseases and pests. There are not many of them, but in stores, you can still find:

  • Fundazol produced as a fungicide, but it turned out that it suppresses ticks and their eggs, inhibits the transition of the larvae of aphids and leaf beetles to the adult stage, and is slightly toxic to whitefly eggs. The solution is prepared from 10 g of the drug and 10 liters of water. They are processed with it during the growing season, that is, in early autumn. Fundazole is toxic to humans, animals and fish, slightly toxic to birds and bees.

    Fundazole is a fungicide capable of inhibiting the development of ticks, aphids, whiteflies

  • Tiovit Jet effective against all fungal diseases and mites. It is also used at the very beginning of autumn at temperatures: +20 ... +28 ° C. The drug is moderately dangerous: it does not harm the plant, birds, fish, animals, it cannot be used during the flight of bees.

    Tiovit Jet - a drug for diseases and ticks

  • Colloidal sulfur will save you from powdery mildew, mites, aphids, thrips, if the temperature is above +20 ° C. Consumption rate for 10 liters of water 50 g of liquid soap and:
    • 40 - 50 g sulfur when processed without leaves;
    • up to 30 g on the leaves.

      Colloidal sulfur is a biological preparation for a complex of problems

Tank mixes

Tank mixtures are compiled immediately before spraying from compatible preparations. Such kits can be found in stores, for example, Garden Saver contains 2 ampoules: with a fungicide and an insectoacaricide. The products dissolve in 10 liters of water.

You can create your own sets:

  • Gardeners have already tested the compatibility of the insectoacaricide Karbofos and the fungicide Skor. In 10 l of water, 60 g of Karbofos and 2 ml of Scor are dissolved.
  • Compatible biological products: Fitoverm, Aktofit, Lipidotsid, Bitoxibacillin. The amount of each is taken according to the instructions, but the volume of water remains the same. For example: we mix Fitoverm (2 ml / l) and Aktofit (6 ml / l), which means that we dissolve 2 ml of the first and 6 ml of the second in 1 liter.

Pesticides in the tank mix can be of different purposes (to solve a set of problems), and one. By mixing 2-3 insecticides or fungicides, they expand their spectrum of action and increase their effectiveness.

Folk recipes

For early and late autumn, film-forming solutions are suitable and will be effective:

  • Dissolve 40 ml of ammonia (10%) in 1 liter of serum, bring the volume to 10 liters with water. Spray the aboveground part and the soil under the bush. During the fall, you can make 3 or more treatments with an interval of 5-7 days.
  • Mix 100 ml of green soap and 100 ml of unrefined vegetable oil. Dilute the resulting emulsion with water to 10 liters, process as in the previous version.

At the end of the season, currants are no longer dangerous and it is desirable to treat them with chemicals, they are more effective than biological ones. But when choosing products, pay attention to the application temperature. Some are only suitable for early and warm autumn.

Shrubs are susceptible to damage depending on the variety. Consider what problems are encountered in the known varieties of currants and gooseberries.

Small insects settle in large clusters on leaves or other green parts of the crop, drinking juices and killing the plant.

Gall aphid

The pest forms reddish swellings on the outer surface of the leaves. Most often affects red currants.

Sprout aphid

Insects damage the tops of young shoots. You can recognize the pest by the folded leaves of the bush. After removal, it is better to burn the affected parts so as not to infect healthy shoots.

Kidney currant mite

This pest is a carrier of terry. The insect penetrates into the kidney, as a result of which it increases in size. Affected vegetative organs are removed before opening. If there are not so many of them, then the plant can be saved. In case of damage to most of the bush, the planting is removed.


Insects are difficult to spot as they are similar in color to the branch. The pest sticks to the bark, sucks out useful juices, gradually leading to wilting and drying out of the plant.

Fireflies, sawers

Butterflies of these pests lay eggs in currant flowers. After the caterpillar eats a certain number of leaves, it pupates and gives a new generation. Moths often emerge from the soil after hibernation. Covering the ground with a film before the flowering of currants will help to avoid this.

The sawyer is a parasite on berries. Affected fruits should be immediately separated and burned.

Powdery mildew

A fungal disease in which spores are carried by the wind. When in contact with shrubs, they grow sharply. Leaves are covered with white bloom. If measures are not taken in time to combat the disease, then the fungus passes to the berries.

Currant pests and diseases

Comprehensive protection of currants from pests and diseases in the spring in the future will affect a good harvest. Depending on the variety, the fruit shrub is more or less prone to damage. However, if no protective measures are taken, even the most resilient culture is at great risk.

The following diseases are most often found in currants:

  • Powdery mildew is a fungal type of disease. Symptoms appear in May with a white bloom on foliage and branches. Over time, the fungus spreads to the berries.
  • White spot is a fungus that appears on the leaf blades with brown spots. They brighten closer to July. A brown edging is formed along the edges of the specks.
  • Anthracnose also belongs to fungi. The disease is manifested by spots of red color on the leaf plate. Over time, they begin to grow in size, taking the shape of a ball.
  • There are two types of rust. If orange pimples have formed on the back of the leaf plate, then this type of disease is called goblet. If the leaf is covered with small red dots, then this type of rust is called columnar.
  • Terry is manifested by a change in the shape of the sheet plate. It becomes elongated with sharp ends. The shape of the inflorescences changes. They become sterile and do not form an ovary.
  • The striped mosaic is manifested by the yellowness of the leaf. At first, it spreads along the veins. A cobweb pattern appears on the leaf plate.

Diseases affect currants due to poor care, weed beds, rainy weather with unstable temperatures. Insects are often carriers of pathogens. For currants, the following insects are considered the most dangerous:

  • The kidney moth most often settles on crops with white and red fruits. The insect loves black berries less. The pest in the form of a larva hibernates under the bark. In the spring it feeds on the buds of a bush, turns into a butterfly. An adult moth lays eggs in fruits.
  • Aphids settle in large clusters on young foliage, green shoots. Insects drink the juice, destroying the plant.
  • Moth is a small butterfly that loves to lay eggs inside a flower. The resulting larvae eat the set fruits and leaves.
  • A kidney mite is a carrier of an incurable disease - terry. The insect settles inside the kidney, which can be determined by its strong increase in size.
  • The glassworm is a caterpillar that lives under the bark in the branches of a bush. The pest eats wood, completely destroying the plant.

Preventive measures, caring for currants in the spring, combating attacking pests, and keeping the beds clean reduce the likelihood of a crop disease.

Spring processing of gooseberries and currants against pests and diseases

The growing processes in northern berry bushes begin much earlier than in most other horticultural crops, therefore, measures to protect these plants from insects and diseases should be started almost immediately after the onset of the calendar spring.

Boiling water

Spring watering of gooseberries and currants with hot water helps to destroy the larvae of most pests that have successfully overwintered in fallen leaves and plant debris. Processing is carried out in early March before the leaves bloom. Plain water is brought to a boil, quickly poured into a watering can or a spray bottle (it is important that the temperature does not have time to drop below 80 ° C). The bushes are poured with boiling water from a distance of about 70 cm so that the water hits all the branches. Water consumption 3-5 liters per bush. The same hot water can be used to irrigate the soil in near-trunk circles: the roots of this treatment should not be afraid, since the ground is still quite cold, and the larvae of pests and spores of fungi "soul" from boiling water will not be able to transfer.

Copper sulfate

Copper sulfate works well against many types of fungi. The substance is not toxic and does not accumulate in berries if used in strict accordance with the instructions. Use it to disinfect the root system of young bushes before planting them in a permanent place. 5 g of the drug is diluted in 10 liters of water, the resulting solution is plentifully watered the soil under the bushes and sprayed on its ground parts (consumption - 1.5 liters per 1 bush).

Bordeaux liquid

The drug protects currants and gooseberries well from many fungal diseases, but negatively affects the taste of berries, so it should be used with caution. The liquid can be prepared at home. This will require copper sulfate, quicklime and plain water:

  1. 100 g of vitriol is poured with a glass of hot water, after a few minutes another 5 liters of boiling water is added.
  2. In another container with a volume of at least 10 liters, 150 g of lime is poured and diluted with 5 liters of cool water.
  3. A solution of vitriol is very carefully poured into a lime solution.
  4. Litmus paper is used to check the readiness of the liquid for processing: the blue color of the indicator indicates a low concentration of the solution, red - about high. The first will be ineffective, the second will burn the plant. The concentration of vitriol is regulated by adding lime solution.

The consumption rate of Bordeaux liquid is 1.5-2 liters for the treatment of 1 bush.


The paste-like agent effectively destroys the larvae of pests and pathogens of most diseases of currants and gooseberries. The drug is toxic and tends to accumulate in berries, therefore it is not recommended to use it on fruit bushes.

Urea (urea)

It is used as a fertilizer, but it also helps protect plants from various dangerous insects (especially aphids). Spring treatment of currants and gooseberries from pests with urea is carried out by spraying the bushes with a solution of 0.5 kg of the product and 10 liters of water.

Biological preparations

Low toxicity products are not as effective as harsh chemicals, but they can be used during all stages of the growing season with the exception of the harvest period.


A widely used biological product against a complex of insect pests of cultivated plants, incl. aphids, sawflies, leafworms, scale insects, etc.


An insecticide, safe for humans and animals, used to destroy caterpillars and larvae of all insects harmful to fruit bushes.


A broad-spectrum insecticidal preparation against caterpillars of sucking and gnawing pests (aphids, currant moths, etc.).


Complex biological product of insecticidal action, destroying larvae and caterpillars of leaf-eating insects.


A biological agent that effectively suppresses the growth and development of pathogenic fungi and bacteria, as well as providing plants with additional nutrition and supporting their natural immunity.

Chemical based preparations

Severely neglected diseases are difficult to defeat with folk or biological means. How to process gooseberries or currants in such cases? Most likely you will have to use chemicals:

  • Topaz or Hom against powdery mildew
  • Cuprozan or Chemicin versus anthracnose
  • Fitosporin against most fungal diseases.

All products should be used strictly following the instructions for use.

Spraying is recommended in cloudy, windless weather, since chemical compounds are easily destroyed by external factors.

Preparations for processing

There are several of the most common drugs that help get rid of pests and plant ailments. Consider the features of each of them in order to determine the optimal solution for solving your problem.

Copper sulfate

Copper sulfate in spring is suitable for processing shrubs and trees. Copper sulfate is considered useful for periodic spraying no more than once every five years. Gardeners note its high efficiency.

The concentration depends on the degree of damage and the type of plant. It is important to carry out recovery and prevention measures in early spring before the appearance of buds. After such treatment, you are guaranteed to get rid of fungal diseases.

For currants, up to 100 grams of vitriol per 10 liters of water will be enough. To obtain a homogeneous liquid, the components must be thoroughly mixed. To disinfect the root system of seedlings, you can soak them in a solution of vitriol for a couple of minutes.


Urea is a proven way to get rid of pests and protect the shrub from disease. Even if your currant overwintered well, fertilizer in the form of carbamide will only help it enrich itself with all the necessary substances, prepare for the fertile summer period.

Top dressing is recommended at other times of the year, if the leaves turn yellow quickly, the bush grows slowly, and the inflorescence is not pleasing to the eye.

Also, urea will help in the event of a poor harvest or when the berries are abundantly crumbled, not having time to reach sufficient size. Treatment with a solution is carried out in dry weather in the morning or in the evening. 40 grams are diluted in 10 liters of water, after which each bush is thoroughly sprayed.

Bordeaux liquid

Bordeaux liquid is a universal preparation based on copper sulfate and hydrated lime. For its preparation, it is enough to combine the indicated components, reaching 1 or 3% concentration.

Bordeaux liquid copes with fungal formations and helps to cure currants from scab, mold, rot, powdery mildew.


Fitospirin is a versatile and prophylactic microbiological preparation suitable for combating bacteria and fungal formations. If you find suspicious symptoms of ailments on currant bushes, apply it immediately in order to prevent danger to your crop.

With the help of phytospirin, spraying is carried out not only in spring, but also throughout the year. Once every two weeks, you can treat the bushes as a preventive measure.

Treatment of currant bushes in the spring from pests.


Probably there is no such dacha where wonderful aromatic currant berries are not grown. However, not everyone can boast of a really good, high-quality harvest.

The reason may be both non-compliance with the necessary rules of agricultural technology, and numerous pests that zealously attack the fruiting currant bushes. Many of the parasites tolerate winter frosts well, and in the spring they begin to destroy currants with a vengeance.

It is possible to significantly reduce the number of pests if the necessary measures for the care of currants are carried out correctly and on time throughout the year.

In early spring, cut out all diseased, dry and broken branches from the currants. Cut the tops of the frozen shoots to healthy buds. Rake and burn old leaves and all trimmed branches, because it is in this wholesome environment that pests hibernate, which with the arrival of spring are activated.

Sprinkle the ground under the currant bushes with ash and loosen. Dig up the soil between the bushes. This allows damage to nests and large concentrations of larvae and spores. In addition, fertilizers penetrate into the soil better.

Then sprinkle the soil under the currant bushes with humus, which will serve as top dressing all summer.

After winter, carefully inspect the currants and early in the spring be sure to spend processing of currant bushes from pests .

Processing of currant bushes in the spring from pests.


Shrub processing

Autumn processing of fruit trees and shrubs: disinfect currant and gooseberry bushes from anthracosis and powdery mildew after harvesting. In the raspberry berry, cut off the last fruit stems on a typical raspberry and collect the remaining berries on a remontant raspberry.

After harvesting, the raspberry tree should be sprinkled with Bordeaux liquid or its substitutes for fungal diseases. On strawberries in autumn, sprinkle with 1% Bordeaux anti-spotting liquid. Grapes in the fall must be properly pruned and wrapped for the winter.

Gardening will require perseverance and free time from you. However, this is a mandatory set of procedures, without which you will not have to wait for a healthy harvest.
