The main diseases of black and red currants

One of the most useful berries is currants. It is used not only fresh, but also dried, frozen, preserved. To get a rich harvest, you should know what currant diseases exist and how to deal with them.

Currant diseases and pests

There are a variety of pests and diseases of currants, and the fight against them is reduced to timely processing, as well as proper care of the plant.

With proper care and timely treatments, the plant will delight with large berries and a stable, high yield.

Noticing the spots on the bushes, changing the color of leaves, gardeners begin to look for currant diseases and stand up to fight them.

One of the most common pathologies is anthracnose. This is a fungal disease that affects all types of currants. At a temperature of about 14 degrees, the fungus is activated. This is manifested by changes on the leaves of the plant: yellowish-green spots appear. Gradually, they become brown in color. Then the spots merge, and the leaves look as if they were burned. Then they begin to wrap up the edges and fall, exposing the lower parts of the shoots. If the fight against currant diseases in the spring and during the growing season is started in time, the defeat of the bushes with anthracnose can be avoided.

Infection with fungus can occur in different ways. Most often it is carried by insects and wind. At high humidity, the fungus spreads rapidly, damaging all available shoots. The disease destroys the bush in just three years.

In order not to manifest fungal diseases of currants, the fight against them should begin in the spring. When the buds swell, it is necessary to treat the plant with a 3% Bordeaux mixture. After flowering, re-treatment with a one-percent solution of Bordeaux mixture. After harvesting, the plant is treated with copper oxychloride.

So that the fungus does not spread, all fallen leaves are collected and burned, and the soil under the plant is sprinkled with ashes.

To combat currant diseases and pests in spring and late autumn, after the leaves fall, the bushes can be sprayed with a 3% Nitrafen solution. In the summer, they use a solution of blue vitriol (diluted according to the instructions) and one percent colloidal sulfur. Processing is carried out before and after flowering, and then after picking berries. When spraying, it is important to ensure that the solution reaches the lower parts of the plant.

To reduce the likelihood of infection with fungal diseases from the ground, the soil under the bush is dug to a depth of at least ten centimeters. Be sure to conduct regular cleaning of weeds. Thickened landing necessarily thinned.

Mealy dew

To get high yields of berries, you should know what are the diseases of black currant and what is the fight against them.

One of the most common diseases of black currant is powdery mildew. It is a fungal disease that rarely affects red and white varieties.

Mealy dew appears at the end of spring - at the beginning of summer. For the disease is characterized by the formation of whitish plaque on the underside of the sheet. In this case, the upper surface begins to noticeably brighten. These are the first manifestations of the disease.

In wet, warm weather, the fungus actively moves from one leaf to another, striking all the young and then old shoots. Leaves become corrugated, shallow. There is a shortening of internodes. The shoots begin to dry up, the berries fall.

On affected leaves, fungus over-winterizes well.

To avoid infection, it is necessary every two weeks to treat the plant and the soil beneath it with a solution of copper sulfate with the addition of soap, as well as other means:

  1. 20 grams of vitriol is diluted in ten liters of water. To this solution add 150 grams of laundry soap.
  2. 50 grams of soda diluted in 10 liters of water and add 50 grams of soap.
  3. Three kilograms of ash diluted in ten liters of water. Means insist day, then the composition is filtered and used for processing plants.

To combat powdery mildew, you can use a variety of special preparations offered in the shops of country goods.

To prevent reinfection, all the leaves from the plant are removed, the fallen leaves are removed, the affected shoots are cut off. All parts of plants are burned.

The fight against diseases and pests of red currant, white and black is reduced to the preventive treatment of bushes and the timely detection of any changes in the appearance of leaves, shoots, berries. This will help to quickly respond to the emerging disease.

One of the dangerous diseases of currant is Septoria, or, as it is also called, white spotting. This type of pathology is characterized by the appearance of yellow-brown spots of an angular shape. Gradually, the edges of the formations acquire a brown hue, and in the center the color becomes white. On the upper side black dots form on the leaves - these are spores. The appearance of the lesion can be seen in the bottom photo. Currant diseases and the fight against them are the eternal problems of gardeners. Success is the timely identification of changes and quick response. If you stretch with the treatment of septoria, by the end of the summer all the leaves will fall off, and the bush will die.

To fight septoria, carry out the processing of plants on the same principle and the same means as with the defeat of anthracnose.

You can see what other types of diseases affect the plants in the photos provided in the article. Diseases of currants and struggle with them worry all gardeners. The latter should be carried out from early spring to late autumn. This will help avoid a variety of fungal diseases, including rust.

Proper currant care, pest and disease control are important components of a successful plant growing in the garden. As you know, bushes can be affected by a disease like rust. For currants are characterized by a variety of rust types, among which the most common are columnar and goblet.

The columnar type is found on those bushes that are planted near coniferous plants. This type of fungal infection is characterized by the appearance of small orange pads on the underside of the leaf. Then spores are formed from these pillows. In autumn, the leaves of the plant are completely covered with orange fungi, the foliage falls, the shoots are not prepared for wintering.

Diseases of black currant and the fight against them - the constant care of gardeners. To cope with columnar rust, you must follow the rules of landing. Shrubs are located remotely from conifers. If suddenly the disease manifested itself, then all the leaves, the affected shoots are removed and burned. During the growing season, for the prevention and treatment of rust, they treat the Bordeaux mixture: before the buds swell, the shrub is treated with a 3% solution, and after picking berries, with a 1% solution.

Another type is glass rust. This type of fungus affects the bushes in early summer. At occurrence of a glass rust on shoots, flowers, leaves pads of a yellow-orange shade appear. With the defeat of parts of the plant, the leaves and ovaries fall off.

Usually this fungus falls on currants with sedge. Therefore, as a preventive measure, it is recommended to mow a sedge with a radius of 500 meters.

Gardeners can observe the yellowness of currant leaves. And if yellowness does not appear because of autumn leaf fall or because of violations of the rules of agricultural engineering, then this may indicate a disease like a mosaic.

When examining the sheet, you can see streaks or stripes of a yellow shade along the main veins. You can see what a defeat looks like in the photo. Diseases and control of black currant should be known to every owner of the plot. It is necessary to take all measures to eliminate the affected bushes. It is better to dig up diseased plants and burn them. This action will prevent the transition of the virus to healthy bushes.

Proper currant care in the spring, combating diseases and pests will help get a good harvest in the summer.

Among the most common pests - aphid. Usually it settles on the lower side of the sheet. In the process of life aphid sucks the juice from the plant. Damage to aphids leaf visible. They are characterized by tubercles on the upper side, which become brownish in color.

Garden ants carry the plant from one plant to another. To prevent the appearance of a pest, it is necessary to begin the fight against the extermination of ants. They feed on sweet juice, which is released by aphids. To kill the colonies, you can use boiling water or use special preparations from ants sold in garden stores.

After the destruction of ants, you can begin to eliminate aphids. There are many different ways to deal with a pest. Someone uses various drugs sold in specialized stores, and someone removes aphids by popular methods. One of these is the following remedy: take tobacco, sorrel, yarrow, dandelion and potato tops in equal parts and mix. Then two glasses of the mixture are steamed with a liter of water. The composition is infused overnight, and in the morning it will feed, and they can process currants from aphids.

Proper care of the currant in the spring, the fight against diseases and pests by folk methods help to preserve the plant and the crop. Folk remedies are safe for beneficial insects, pets.

The treatment of plants with the above means is carried out at least five times per season with an interval of two weeks.

Gooseberry ognevka

At the moth is light green larvae. They are very nimble and try to fall from the leaves to the ground. Usually the moth appears during the period when the berries begin to ripen. The larvae develop about a month, then fall to the ground and go to the ground until next year. With the development of a fireworm greatly damages the plant.

To control pests and currant diseases, the photos of which you see in the material, should be correct.

It is possible to overcome the fire by destroying the affected brushes with berries. Find out exactly where the pest sits, you can on the web.

If there is a lot of moth, then you can treat the bush with tobacco infusion (half a glass is poured with a liter of boiling water and the night is infused). To destroy the pest in the ground, it is necessary to dig up the earth under currant bushes in late autumn.

Glass cup

Pest currant glass is one that is difficult to fight. Caterpillars penetrate deep into the shoots, eating the core. In this way they gradually eat their way down to the roots of the plant.

With the defeat of the plant glass leaves shallow, can die individual branches. They must be removed and burned. In case of severe damage to the pest caterpillar, the currant is uprooted and the bush is completely burned. The fight against diseases and pests of black currant is the timely processing of bushes.

To prevent a glass case, it is recommended that the bushes be treated with a solution of "Karbofos", "Fufanon" or other means designed to combat the glass case.

Nectrimal drying of the shoots

For the red and white varieties of currants is characterized by such a disease as non-spritter drying of the shoots. Allow to see how the diseases of red currant look, photo. The fight against fungus should begin in early spring, from the moment of kidney swelling.

The disease is manifested by the formation on the shoots and branches of orange dots. Gradually, they grow and turn into big brown mounds. During the beginning of the ripening of the fruit, the affected areas are painted black. When young shoots are damaged, the shoots dry out and die.

If you do not start treatment in time, you can lose the whole hive. When the first signs of damage appear, the currants are cut, the affected parts are burned. Places slices necessarily treated with garden pitch or Bordeaux mixture.

To prevent infection, it is necessary to regularly remove weeds, fallen leaves, to carry out timely feeding of the plant. With proper care, the plant is not afraid of any disease.

Spider mite

This pest begins to actively damage currants with the onset of warm days. In April, spider mites crawl out of wintering grounds and make their way to the branches. Detect pests can be on the underside of the leaves. On examination, the cobweb on which the tick sits is visible.

In the course of his life, he actively absorbs currant juice. This is manifested by the formation of light spots on the upper side of the sheet. With a strong lesion, the plant dries.

To cope with a spider mite, you can use "Akarin" (divorced in the proportion of 1 gram per liter of water) or use folk remedies. Infusion of garlic or onion peel is considered one of the best.

When forming buds, the activity of the gall midge begins. During this period, the females lay eggs on the surface of the leaves. After hatching, the larvae feed on currant leaves. This causes premature yellowing and abscission of foliage. You can fight gall midge by treating the bush with a Ditox solution (400 grams are diluted in a liter of water).

Currant treatment in early spring

For the prevention of diseases of the white currant and fight against them they carry out timely processing. The best time to start spraying is considered to be early spring, before sap flow.

Begin spring spraying with hot processing. This helps the bush to fully develop.

To carry out the hot spraying, you must take the water, heated to a temperature of 80 degrees, and pour it with the bushes. On one bush will need about three liters of water.

After the shower, pruning of weakened and damaged branches is carried out. Also on all branches pruned tips, which over the winter frostbite.

During treatment, all buds and twigs that are affected by the mite are removed. After these works, the ground under the bush is necessarily cleaned from all the cut branches.

To prevent the pest from penetrating from the ground, it is necessary to dig up the ground by about ten centimeters, and pour any preparation for pests and fungal diseases from above. This can be Bordeaux mixture or any other tool that can be bought in a special store.

Disease treatment

In the spring, at the time of blooming buds, it is necessary to spray the bushes with various solutions that prevent the development of currant diseases.

It is recommended to treat the plant and the soil under it with a 2% solution of Nitrofen or Karbofos.

A week later, Bordeaux liquid is treated according to the instructions. As a preventive measure, it is also possible to carry out the treatment with "Fundazole" (according to the instructions).

As the plant develops, it is processed by aphids and other pests that appear on currants. It is best to treat the bushes once every two weeks with products designed to combat various pests. This will serve as a good preventive protection against the appearance of pests.

During the growing season, about three treatments of currants with antifungal solutions are carried out. This may be Bordeaux mixture, "HOM" or any other means. The folk remedies have also proven themselves well in currant processing. Ash, infusions and decoctions of dandelion, garlic, onion peel, yarrow help from the pest. Among these funds, special attention is paid to ash. It not only helps to fight some pests, but also perfectly protects currants from fungal and viral diseases.

How to deal with terry?

The main causative agent of currants terry kidney mite. Terry currant characteristic ugly state of the extreme leaves. As the disease progresses, the flower brush becomes thinner, and the scales replace the flowers.

There is a strong stretching of the leaves of young shoots. From the five leaves, they turn into three leaves. Veins become rough. The color of the foliage becomes dark green. Disappears spicy aroma, characteristic currants.

How to fight? Spray the plant 1% suspension of colloidal sulfur or lime-sulfur decoction.

The treatment is performed during the period when the mite leaves the old kidneys. After 10 days, re-treatment.

If the damage is severe, two more spraying is required (upon completion of flowering and berry picking).

For the treatment of currant from the terry it is necessary to spray the bush with 1% suspension of colloidal sulfur or lime-sulfur decoction

White spot or septorioz - what to handle in summer and spring?

White spot or septoria causes the fungus Septoria sibirica. This ailment is one of the most common.

Septoria is characterized by the appearance of small brown spots on the surface of the leaves. In the future, they become white, but the brown edging remains. Spots are able to spread on berries.

Harm from white spot:

  • premature leaf fall
  • stop the growth of the bush and its wilting,
  • crop failure.

For the treatment of currant plantations and soil carry out processing "Nitroferon" or copper sulfate in the form of a solution. The event should be carried out in the spring before the start of bud break.

В летнее время допускается проведение четырёхэтапной обработки 1 % раствором бордоской жидкости или хлорокиси меди.

Для профилактики необходимо monitor soil moisture, timely destroy dead foliage, make black currant plantings, process and dig up soil in the autumn and early spring period.

From white spot, currant treatment should be carried out in spring and summer: “Nitroferon” or copper sulphate in the form of a solution, 1% solution of Bordeaux mixture or copper oxychloride

What to do with rust?

There are two varieties of rust currant: columnar and goblet.

Crown rust causes mushroom Cronartium ribicola Dietr. The pathogen has a negative effect on foliage.

On the underside of the leaves, orange growths develop, which, when powdered, form many bright spores. Yellow spots appear on the upper side of the leaf.

Columnar rust appears on currant bushes in early August and is rapidly spreading. The disease causes a massive fall of the leaves ahead of time and reduces yield.

Also, with columnar rust, there is a decrease in the growth of young animals and a decrease in nutrient reserves.

Cup rust rust is caused by the fungus Puccinia ribesii caricis. With this disease, bright orange pads develop on the foliage, flowers and ovaries.

Active infection occurs at the flowering stage. For this reason, flowers and ovaries are badly damaged.

Humid climate and neighborhood with sedge favorably acts on the harmful fungus. Glass rust affects almost all foliage and flowers. This causes their premature fall and leads to a significant decrease in yield.

Two varieties of currant rust are distinguished: columnar and glass, spraying is carried out with Topaz, Previkur and Fitosporin-M, 1% Bordeaux liquid

For both types of rust currants can be treated equally. Fungicides "Topaz", "Previkur", "Fitosporin-M" inhibit the development of the pathogen, do not allow disputes to ripen and divide.

Also allowed to spray bushes with 1% Bordeaux liquid.

As prophylaxis transplantation of plants on a hill, drying of the soil, removal of sedge thickets.

Why does off-shot drying of shoots occur?

Nectrimal drying of the shoots causes the fungus Nectria ribis. The disease is characterized by the formation of orange-colored spots on the branches and shoots.

They gradually grow and are transformed into bulk tubercles. At the stage of maturation of the spore, the tubercles are colored black, and the young processes dry and die.

When the first signs appear, it is necessary to start a struggle: to cut off the infected branches and burn them. Sections are sanitized by Bordeaux mixture and treated with garden pitch.

For prophylaxis should regularly remove weeds, remove fallen leaves and feed.

Nektrievaya drying of the shoots are treated by pruning infected branches and burning them, the sections are disinfected with Bordeaux mixture

Striped mosaic: disease control measures

Striped mosaic is a viral disease. Ailment is characterized by the appearance of a bright yellow pattern on the leaves around the main veins after blooming.

No cure for striped mosaic: Infected bush should be removed.

If a currant bush is affected by a striped mosaic, the bush should be removed.

How to process a bush from currant leaf midge

Currant leaf gall midges are brownish yellow mosquitoes. Insects lay eggs on young leaves of growing shoots.

Unblown leaves are damaged by the larvae. In the future, they disfigure and die. Shoots stop their growth and begin to branch incorrectly.

Damaged shoots should be cut. no hemp in summer or autumn (until mid-September). Be sure to dig up the soil in the autumn season.

To get rid of currant leaf midge need spring in the time of budding to treat plantings insecticides

What diseases threaten red currants?

Like other species, red currant is subject to fungal and viral diseases. The most dangerous among them is the terry. This is a very insidious virus, as it develops, it changes the appearance of the bush and leads to currant infertility. Most often it affects the black currant, but since the carrier is a kidney tick, settling on a red one, the bushes with scarlet berries are also not insured from it. If no signs of a kidney tick were found on the currant, the virus was transferred with planting material or through infected garden tools. Reversal - Terry is a popular name - it does not develop in one year, and the longer an infected shrub remains in place, the higher the risk of disease of other plants.

Determine the presence of the virus during flowering:

• the currant lacks flavor,

• flowers are ugly, greenish or dirty pink (up to purple), with pointed elongated petals,

• leaves are darker than usual, more dense and wide, with three corners instead of five.

Because of the terry, the inflorescences do not develop: not having had time to give the ovary of the berries, they fall off to the ground. The virus is not cured: the infected bush will lie down for removal. For several years, currants can not be planted in this place.

Another common virus is striped mosaic. On the leaves of an infected plant, along the vein, a bright pattern appears, gradually filling the entire surface of the leaf. This leads to a decrease and a complete lack of harvest, and the death of the plant. Just like with terry, a bush with a virus is uprooted and burned.

Red currant: disease and treatment. How to beat anthracnose?

In common people it is called a flyworm. For red currants, it is even more pernicious than for black or white. Infection can be identified by spots: first, small brown dots on the leaves gradually increase in size, and, merging, form tubercles that deform and disfigure the leaves.

This leads to their fall: in the red currant even a few spots can cause premature leaf shedding and a sharp decrease in yield.

It is good that anthracnose is treatable:

• spraying the bush and the ground around it with a solution of blue vitriol or “Nitrafen”: this must be done before bud break,

• spraying three times with 1% solution of Bordeaux mixture after flowering with a frequency of two weeks,

• recommended fungicides "Titan", "Agrolekar", "Title 390".

Disease prevention gives a very good result, not allowing the fungus disputes to spread through the garden:

• in autumn and spring, they dig up the soil around the bush,

• fallen leaves, in which the fungus winters, are collected and burned,

• do not allow thickening of the bush and carry out timely pruning,

• before use, scalded garden tools are boiled with boiling water so as not to transfer spores to healthy plants.

Since anthracnose leaves leaves and shoots other than leaves, treatment should be quick and complex.

Glass rust

One of the most unpleasant diseases. The lower surface of the leaf is covered with small orange spots, which, if you do not take measures, grow into “glasses”: it is in them that the fungus spores mature, which at the end of summer are transferred by wind to neighboring bushes and ... sedge. If there are thickets within a half kilometer radius of the site, then it is from there that rust has flown over to your site. It is necessary to get rid of the sedge: in the spring the rust spores are carried by the wind onto the currants.

In addition to the standard treatment of Bordeaux mixture and fungicides, there is a proven popular recipe:

• make two infusions: for the first, take 1 cup of garlic cloves and 2 liters of water, for the second 200 g of tobacco and 3 liters of water. Both infusions to keep in a dark place for 2-3 days, strain, and then drain into a 10-liter bucket,

• add to the bucket 1 tsp. ground pepper, 1 tbsp. l any liquid soap, insist 3 hours, drain.

The composition is prepared in advance: to spray the plants to combat the diseases of red currant need to bloom before. The residue of garlic, tobacco and pepper can be used as mulch. After a couple of weeks, the bush is sprayed with an infusion of onion peel.

And if there is no trust in folk remedies, then you can purchase special preparations: Agrolekar, PropiPlus, Prognoz, and Chistoplor.

Septorioz on red currants

It should be noted that red currants are not as often affected by white spot as other species. However, sometimes this happens - it means you need to be treated.

The disease begins with the appearance of brown spots. As they grow, the center of the spot fades, and as a result, a large gray-white spot with a brown border remains on the leaf plate.

Septoriosis is treated with practically the same methods as anthracnose, its pathogen also tolerates winter in fallen leaves. In addition, you can use the fungicides: "Cichome", "Fitosporin-M", "Chistophlor" and "Prognoz". For the prevention of the appearance of the disease, the currant bush is sprayed with Bordeaux mixture, copper sulphate or Nitrafen before flowering. Be sure to thinning the bush and remove shoots with signs of septoria.

Sphereotek red currant: what is this disease? Powdery mildew treatment

The name "powdery mildew" is more familiar to the gardener. This disease delivers a lot of trouble with its frequent relapses, but it is already well known and studied, so there is a chance to win. Signs of defeat currant powdery mildew:

• the appearance on the leaves and fruits of light gray bloom, which gradually acquires a brown color,

• leaf deformation: twisting, shedding,

• Fall of unripe berries.

The danger of the sphere library is that due to the disturbed growth, the plant becomes less winter-hardy, and if it survives the winter, the powdery mildew will overcome the bush completely next year and move on to the next plant.

The measures of struggle include:

• full spraying of currant fungicides,

• folk remedy: a solution of soda ash (50 g per 10 liters of water),

• prepare a solution of mullein and water in a ratio of 1: 3, insist 3 days, once again breed in the same proportion and weekly spray the infected shrub.

Among the fungicides, “Alirin-B”, “Baktofit”, “Tiovit Jet”, “Fitosporin-M”, “Topaz” can be used.

There are preventive measures to combat powdery mildew. This is a mandatory pruning of damaged shoots, cleaning and burning of fallen leaves. You can not treat this with disdain, because if you do not destroy the infected parts of the plant, the spores of the fungus-pathogen will sooner or later be on other plants, and the whole course of treatment will have to start all over again.

In general, methods of combating diseases of red currant do not differ from the treatment of bushes with black or white berries. It is just that some diseases are subject to more or less: this must be taken into account before starting treatment in order to have time to save the plant.

Black and red currants: diseases and treatments

Known disease of red currant (black is less common), powdery mildewthat appears when exposed to the marsupial fungus Erysiphales. At different stages of the disease, the surface of young leaves and fruits is covered with a white friable bloom (You can see how the problem looks in numerous photos on the Internet). If signs of powdery mildew are present in the crop grown in your garden, treat them with Fitosporin or pharmacy iodine. With the low effectiveness of such an agent, apply 1% bluestone. If you do everything right, the illness will be damaged in the shortest possible time. The main preventive measures are:

  • proper care
  • regular use of dressings,

Among the common fungal diseases of currants should highlight anthracnose. The problem occurs when growing crops in conditions of high humidity. The fungus forms its colonies on green young shoots. The early stages of anthracnosis are accompanied by the appearance of tiny dark spots that grow in size as the disease progresses. Further development of the disease is accompanied by deformation of the leaves and fruits, and then, a complete deterioration of the external condition of the bush. Different forms of anthracnose lead to premature falling of foliage and worsening of the winter resistance of the plant.

Treatment of the disease in red and black currants is carried out with the help of "Fitosporin", "Previkur", "Acrobat", "Ridomila" and other medicines. It is known that fungal spores have the ability to hibernate on fallen leaves, therefore, for productive control, infected leaves must be burned.

Combat terry

Such a problem arises as a result of vital activity. kidney mite. Terry leads to the loss of decorative appeal and the ugly state of the extreme leaves.

Further progression of the problem is accompanied by a thinning of the flower brush, as a result of which, the flowers are replaced by scales. The leaves on the young shoots are strongly drawn out, and the five-leaf copies become three-leafed. The thickness of the vein increases, and the color of the foliage becomes dark green. The spicy flavor disappears.

To effectively deal with such a disease of black and red currants, gardeners use a 1% suspension of colloidal sulfur or lime-sulfur decoction. Treatment will be useful in the stages of mite excretion from old kidneys. The procedure is repeated after 10 days.

If the damage is represented by too strong a form, two more events will have to be applied, as the flowering is complete and the fruit is picked.

White spot, fighting disease in summer and spring

The appearance of white spot on currant leaves is a merit of the fungus septorioza. The disease is considered the most common and dangerous, so you need to deal with it radically and quickly. The activity of the fungus leads to the formation of small brownish spots on the upper side of the leaves. In the future, these parts get a white color, keeping the brown edging. In this case, the spots quickly spread to the berries. How does the condition of the affected bush, you can find out with hundreds of photos that are available at gardening resources.

It is known that such a dangerous fungus is capable of hibernating on fallen leaves, and its spores can move to the surface at high humidity, for example, in rainy weather or with abundant watering. Leaves are affected by spotting on the underside. Among the final consequences of the development of the disease:

  • premature leaf fall
  • the deterioration of the growth of currant,
  • yield loss

In the fight against white spotting, it is necessary to treat bushes and soil mixture with the preparation "Nitroferan". Also, a solution of copper sulfate, which is sprayed with an infected plant in the spring, during the period before bud break, is not bad.

In the summertime, it is possible to realize 4-stage treatment with 1% Bordeaux composition or copper chloroxide. As for preventive measures, they include the control of soil moisture and the timely removal of fallen leaves. It is also necessary to dig and cultivate the soil in autumn and early spring.

Rust treatment

Among the common diseases of currants, known rust. This problem is represented by two forms:

As they become infected, orange growths appear on the underside of the leaves, which, as they grow further, lead to the formation of many bright spores. As a result, the upper part of the leaf is covered with yellow spots. Columnar rust can affect currant bushes in the period from early August to mid-autumn. The progression of the disease is accompanied by a massive fall of the leaves and a deterioration in yield.

In addition, this disease causes a decrease in the nutrient content in the culture, and adversely affects the growth activity of young shoots.

Rust type of glass leads to the development of bright orange pads on the foliage, flowers and ovaries, which, as infection develops further, lead to severe damage to the flowers and ovaries.

Humid climatic conditions and proximity to sedge leads to the rapid spread of harmful fungus, which is why all the foliage and flowers are under the influence of the pest. As a result, leaves fall and yield loss occurs.

To combat two types of rust use fungicidal drugs, including Topaz, Previkur, Fitosporin-M and others. Experts advise to spray bushes with 1% Bordeaux mixture.

For preventive purposes, you can transplant the crop to elevated places, dry the soil or remove sedge thickets.

What causes off-shoot drying?

Dangerous disease in the form of off-drying shoots appears as a result of the activity of the fungus Nectria ribis. The progression of the disease leads to the appearance of orange spots on the branches and young shoots. As they grow, these specks turn into large bumps that are colored black. In the end, the young processes dry up and die.

In the absence of proper and timely treatment, the hive completely dies.

If you notice signs of off-shoots, prune the infected branches as soon as possible and burn them. After that, the slices formed need to be disinfected with a mixture of Bordeaux mixture, and then with a garden shaft.

Preventive measures consist of regular cleaning of the soil from weeds and fallen leaves, as well as the use of fertilizing.

Кроме этого, черная и красная смородина часто подвергается полосатой мозаике. Это вирусное заболевание сопровождается появлением ярко-желтых узоров на листьях в районе основных прожилок. Бороться с проблемой какими-нибудь профилактическими методами или лекарственными препаратами бессмысленно. Остаётся удалить зараженный куст.

Смородинная златка и паутинный клещ

Greenish-copper bugs up to 9 millimeters long prefer the juicy core of the currant branches. As a result, the upper part of the shoot dries out, and then the bush completely ceases to be viable. Ultimately, the fruiting bush worsens.

To get rid of currant Zlatka should be low pruning and burning of affected branches.

Very dangerous pest for currants is a spider mite. It is a sucking insect with a tiny size, which lives on the underside of the sheets and braids its entire surface with a thin web.

At different stages of the lesion, the sheets are covered with bright dots, which gradually increase in size and cover the plate completely. Heavily damaged sheet plates become marble, dry up, and then completely fall off. Active development of ticks is seen in July and August. Treatment methods are as follows:

  • In the spring it is necessary to spray the infected shrub with acaricides, observing the correct dosage. Otherwise, the sheets may be burned,
  • A strong form of injury involves the use of re-spraying with the additional use of chlorophos solution,
  • Preventive measures consist of the destruction of fallen leaves and digging up the soil,

How to deal with currant glass bowl?

A tiny butterfly measuring 1.5 centimeters called currant glass bowl can debug up to 60 eggs in the cracks of the bark of branches. As a result, numerous caterpillars are formed of them, which, as they develop, begin to nibble at the core of the branches and lay their shoes in them for the next winter.

As early as next autumn, they turn into two-centimeter individuals, however, they still remain in the bark, not getting to the surface. As soon as May comes, the larvae gnaw through the exit and begin the process of becoming a butterfly. When the flowering of the currant ends, the damaged parts wither and dry.

Preventive measures include regular inspection of the plantation to determine the activity of the pest. It is enough for the gardener to regularly trim the damaged parts of the bush and spray it with special preparations.

Firestrike: how to get rid of the pest

Among the common currant pests should be highlighted a little gray butterfly called flameworm. Its size rarely exceeds 1 centimeter, but life activity is accompanied by terrible consequences and losses. During the flowering period of the butterfly, the pest lays numerous eggs in the flowers of red or black currant. As a result, they are affected and dry up.

It is very simple to detect the presence of such a pest on a crop: you will see hatched caterpillars on a bush and a characteristic web of berries. Caterpillars are able to feed on currant berries. Unfortunately, there is no effective fight against such a problem. It remains to cover the affected bush with roofing material or linoleum before flowering.

By following such recommendations, you can protect your currants from the attack of numerous diseases or pests.

Conclusion

Many gardeners grow on their plots the most different varieties of currants. Unfortunately, this plant is very often sick, it affects pests. To protect the bushes, it is necessary to carry out timely processing, properly care for the plants.

If cure currants for any reason fails, the plant is dug and burned. All loose parts are also collected and burned. This is necessary in order to protect other currant bushes from infection. In the place of an injured plant, another is allowed to be planted not earlier than in three years.

How to save the crop from currant Zlatka?

Currant Golds - greenish-copper beetles up to 9 mm long. The legless, flattened larvae with an enlarged anterior end are yellowish-white. They prefer the core of the currant branch.

The top of the damaged shoot dries out, and then the whole shoot dies. As a result, fruiting bush decreases.

To get rid of currant Zlatka need conduct low pruning and burning of affected branches.

How to spray from spider mites?

The spider mite is considered a small sucking pest. He lives on a sheet from the bottom and he weaves the surface with his cobwebs.

Damage is characterized by the formation of a bright spot at the beginning of the infection, then a complete discoloration of the area. Heavily damaged sheets take on a marble look, eventually drying and falling.

Active development of ticks occurs from July to August.

For spring treatment (during bud break) the bush is sprayed with acaricides. Drugs with sulfur can cause leaf burns.

With a strong defeat spend re-spraying. Acaricide can be added to the chlorophos solution and applied after flowering.

For prophylaxis fallen leaves are destroyed, and the soil is dug up.

To get rid of spider mites in spring, currants are sprayed with acaricides.

Sphereoteka (American powdery mildew)

The causative agent is a fungus of the genus Spherotec (Sphaerotheca). The first signs of infection of the currant with a sphere library are already noticeable in May: the leaves, stalks of the bush, and later the fruits are covered with white bloom (later the color turns brown). Then the berries become smaller and lose sweetness, the diseased bushes do not have time to grow and die. The development of the disease is promoted by high humidity, dry soil saturated with nitrogen.

Septoriosis (white spot)

The causative agent is a fungus of the genus Septoria. As well as for other fungal diseases, the most suitable conditions for the development of white spot - high humidity, low light, thickened planting. Brown spots appear on currant leaves (2-3 mm in diameter), which become lighter in the center by the middle of summer and become brown at the edges.

Control measures

The affected parts of the plant should be immediately cut and burned, and the bushes themselves should be treated with a fungicide (Fundazol, Topaz, etc.). For the prevention of the sphere library in the autumn, it is necessary to clean the fallen leaves, thin out the bushes. It is also effective dusting wood ash.

Septoriosis (white spot)

The causative agent is a fungus of the genus Septoria. As well as for other fungal diseases, the most suitable conditions for the development of white spot - high humidity, low light, thickened planting. Brown spots appear on currant leaves (2-3 mm in diameter), which become lighter in the center by the middle of summer and become brown at the edges.

Reversion (Terry)

Viral disease, from which it is impossible to cure the plant. Signs of currant terryiness: the appearance of the leaves changes - they lengthen and become pointed, later the fruitless flowers of irregular shape grow.

Currant anthracnose (lat. Pseudopeziza ribis)

The causative agent of this disease is the mushroom Colletotrichum orbiculare. The first manifestations of infection can often be seen in the middle of the summer season. Main symptoms:

  • leaves appear red and brown spots of small size (up to 1 mm) with dark tubercles in the center,
  • spots gradually increase, hitting the whole leaf,
  • leaves dry out and fall off.

This disease is typical for all types of currants, but it is especially common on red. In the rainy season, the fungus is more active and dangerous for the plant. Its spores can easily tolerate winter on plant debris. Finding on the site currant anthracnose treatment should begin immediately.

To do this, use Bordeaux liquid (0.1 kg of the drug per 10 liters of water). Spraying is carried out immediately after detection, and again - after harvesting berries.

To prevent the disease, you can use simple preventive measures:

  • all fallen leaves and plant residues must be removed from the soil and burned,
  • It is not recommended to plant young healthy bushes in the place where there was an infected plant.

Rust on currants (lat. Puccinia ribesii-caricis)

It is possible to detect rust on bushes at any time of the season. There are 2 types of it:

  • cup-shaped - expressed in the presence of bulging orange humps on the leaves, resembling warts,
  • columnar - small orange dots form on the leaves. Pillar rust on the currant appears as an orange bloom.

Columnar rust

This disease differs from bead rust in that on the underside of leaves the orange pads gradually turn into horn-like spore columns, which look like felt. By the end of the summer, they turn brown and cover the affected leaves like a nap.

Infection with columnar rust is most often associated with Siberian cedars and five-pine conifers - spores matured on currants settle on them. And those that develop on homochniki, again infect currants. On berry bushes, the first signs of a lesion become noticeable in June.

Prevention and control measures:

  • plant currants as far as possible from the coniferous forest,
  • collect and dispose of all the fallen leaves of the currant,
  • carefully dig the soil in the berries,
  • apply organic fertilizers and ash in the spring under the currants,
  • feed currant bushes with fertilizers with microelements: zinc sulphate and copper sulphate,
  • spray in the spring and autumn with the same drugs used for anthracnose,
  • in case of severe damage spray the bushes with Bordeaux mixture.
The curved rust of the currants significantly reduces yields. The disease belongs to the fungal diseases of currants. Spores of the fungus overwinter on fallen leaves and spread by water in wet weather.

Black currant reversion, or Terry ramus (lat. Ribes virus 1)

The causative agent of the disease is Ribes virus 1, and the vector is a kidney tick. The virus leads to a mutation of the original form of the species and infertility of the plant.

The main symptoms are:

  • leaf shape change: lengthening, asymmetry, the presence of sharp teeth, the leaves can become three-lobed,
  • reducing the number of veins,
  • leaves may turn purple
  • flowers become elongated with narrow petals,
  • no fruiting and characteristic smell of the plant.

Detect a similar disease can be already in the flowering period. Infected plants are a source of infection for healthy, so the first must be removed. Drug treatment or pruning will not be effective.

You can prevent terryiness in the following ways:

  • for planting it is necessary to choose only healthy and proven material,
  • Potash and phosphorus supplements make the plant more resistant to disease,
  • an excess of nitrogen supplements reduces immunity to the virus,
  • After harvesting, the bushes are treated with Karbofos according to the instructions.
Sick bushes bloom and bloom a few days later healthy. It also signals the presence of the disease. Terry flowers do not give berries or small and ugly fruits form from them.

Striped Black Currant Mosaic

Striped mosaic is a viral disease. Characteristic signs of the disease: a pattern of gray-yellow color appears near the veins of the leaves.

Infection occurs by grafting a diseased cutting onto a shrub, by cutting with one tool of an infected plant and then a healthy plant.

Also other carriers of the disease are known - it is a kidney tick and aphid. There is no cure for the striped mosaic: the infected shrub should be removed.

Currant pests, signs of their appearance

A variety of currant pests not only cause damage to all parts of plants, weakening them and destroying the crop, but often serve as a backdrop for the development of currant diseases, and sometimes as carriers of viruses. The most dangerous pests are discussed below.

  • Black Currant Mite

A characteristic feature of infection is the wintering of the tick directly in the affected kidneys. External signs of lesion currant following:

  1. Tick-borne buds do not bloom in spring, swell unnaturally and dry up. Mites hatching in a dead kidney migrate to other shoots, affecting new buds, where they can give another 1-2 generations.
  2. Infected with a small number of ticks buds bloom, forming underdeveloped shortened shoots, the bushes do not ripen and are subject to freezing.

The omnivorous pest, which weakens the bushes strongly, hibernates on the shoots and can subsequently develop on all parts of the plant. Young shoots and leaves are most susceptible to damage.

Pictured currant bud mite

  • Aphids on currants

Features of aphid parasitism are presented below:

  1. Insect generations come out of eggs in spring, and when warm and humid weather sets in, they multiply rapidly, and the population is undulating.
  2. Mature light green individuals are visible to the naked eye, colonies are more often localized on the underside of leaves and tops of the shoots.
  3. Affected leaves swell in the form of light bubbles, shoots bend and remain undeveloped.
If there are already berries on the currant, then it is not worth sprinkling the aphids with chemicals. You can fight with aphids by folk methods: the infusion of onion peel, the infusion of marigolds. Also, the aphid does not like red pepper, tobacco, ashes.
  • Currant Zlatka and glass

The insect larvae of these species infect the currant branches and in a short time with a strong infection can completely destroy the plantations. Determine the presence of pests as follows:

Suspicion of defeat by the larvae should arise if in the spring the gardener observes the withering and drying currant shoots. Cutting along such a shoot, one can see inside an oblong dark course, in which either the legless larva of the currant beetle beetle or the white caterpillar of a currant glass bowl are present.

The larvae of both species pupate in May, in June the years occur, and the larvae hatch again in July, damaging the shoots.

In the photo is a pest butterfly glass. The flight is observed in the last days of June, just about 2 weeks after the flowering of the black currant. With straightened transparent wings, its size reaches 25-28 mm. A small oblong body all in dark gray scales. And only the belly plowing the light transverse stripes: the male has 4, the female - 3.

  • Gooseberry moth

Gooseberry moth is a butterfly with wings covered with black and yellow spots. Usually, she prefers gooseberries, but she also wants to eat currants. Laying eggs occurs on the back of the leaves.

Emerging caterpillars devour the leaves from all sides. In the middle of summer, they turn into pupae and are hung along branches.

For prevention it is necessary:

  • carefully clean and cultivate the land
  • collect all the pupae in July and destroy,
  • process urea in the fall,
  • spray plantings ("Fitoverm", arsenic calcium DDT and others).

How to spray currants from pests

Cutting and burning damaged shoots, digging the soil under the bushes remain the main measures to reduce damage from pests on currant landings.

For complex protection of berries, obligatory treatments are carried out in the following periods:

  • After bud break

Against aphid, apply 0.1% emulsion of 25% anometrine-H, solutions of decis, condor or calypso in concentrations according to the instructions of the preparations.

  • Before flowering and immediately after it.

Processing of colloidal sulfur contribute to the destruction of not only the powdery mildew, but also detrimental to the currant mite. To do this, spray the bushes and the ground beneath them with a 0.5% sulfur suspension prepared according to the recipe suggested above.

  • 20 days after flowering.

Currant bushes are sprayed from goldfish and glass case with a 0.9% emulsion of 10% karbofos, a 0.3% solution of chlorophos, or a preparation BI-58. The use of drugs in this period is effective in the foci of high pest spread, as there are years of mature individuals.

Folk remedies in the fight against diseases and pests currants

Restricting the use of pesticides significantly improves the ecological compatibility of the crop, in many cases folk remedies are quite effective and much more accessible than modern chemical remedies.

With the defeat of aphids, ticks, other sucking pests effective treatment of herbal preparations, prepared according to the following recipes:

  1. Fresh garlic in a mass of 100-200 g is pounded into a meat grinder, 10 liters of water are poured, filtered and immediately treated diseased plants.
  2. Husk onions weighing 200 g pour 10 liters of water and insist 4-5 days.
  3. Dandelion leaves (400 g) or plants with roots (200 g) pour 10 liters of water heated to 40 C and leave for 2 hours.

For the control of gold and glass in the same time as in the processing of pesticides, that is, 20 days after flowering, use such means:

  1. Soap emulsion, prepared at the rate of 200 g of crushed soap on 10 liters of warm water.
  2. Broth wormwood is prepared from 1 kg of raw material, pour it with 2-3 liters of warm water and boil on low heat for 15 minutes, leaving to infuse for 5-6 hours. Bring the volume to 10 liters of water and process the plants.
  3. Green potato tops (1 kg) are crushed, poured 10 liters of water and infused for 4 hours.
  4. Во время лета насекомых устанавливают ловушки с фруктовыми сиропами , периодически их проверяют и уничтожают вредителей.

Правила ухода и меры профилактики

Чтобы посадки смородины были здоровыми и неизменно радовали урожаем, необходимо придерживаться ряда несложных правил ухода за растениями:

Обязательными агротехническими приемами являются:

  • planting seedlings with a root deepening of 3-5 cm and cutting the shoots, so that 2-3 buds remain above the ground,
  • timely watering and mulching the soil with peat, compost or humus, replacing bushes older than 7 years old with young plants,
  • the correct annual pruning, in which every year 2-3 best basal shoots are left, and the rest are cut.

Currant glass and plant care

Currant glass bowl - this is a 1.5 cm long butterfly. It is covered with black scales with a lilac shade. On the abdomen of the glass case there are light transverse stripes.

Female pests are able to lay up to 60 eggs in the cracks of the bark of the branches. The white caterpillars that appeared appear gnaw through the core of the branches and make wintering walkways in them.

By next fall, they reach a length of 2 cm, but do not go outside. They are inside the currant branches spend another winter.

At the end of May, the larvae gnaw out and pupate. In June, butterflies fly out. After flowering, the branches damaged by the larvae wither and dry.

For prophylaxis regular inspections of plantings with signs of glass. It is important to carry out pruning and destruction of damaged branches in time.

To get rid of currants glass you need to prune and destroy damaged branches.

How to get rid of firearms?

Firestrike is a small gray butterfly 1 cm long. The pupae of the flame-guns winter over currant plantations. During flowering butterflies lay eggs in flowers. This leads to the defeat of the flower.

The presence of pests can be determined by the presence of hatched caterpillars on a bush and spider web tangled. Caterpillars feed on currant berries.

This cover will not allow pests to get out of the soil. After flowering sheets can be removed.

For prophylaxis from fire damage, cover the soil around currants with roofing material or linoleum before flowering.

Anthracnose disease blackcurrant

In black currant, the fungus mostly affects the leaves, and in the red and white, their petioles and fruits. The disease begins to develop in the spring, as soon as the air warms up to 15º C. The first symptom is small reddish-brown spots. Gradually, they increase in size, merge. The leaves and brushes of the fruit twist, dry and fall in the middle of summer. The bush's frost resistance is sharply reduced. The development of the disease contributes to heat and frequent precipitation. If summer is given dry, anthracnose infection is practically excluded.

For prevention, the stem close to the trunk is thoroughly cleaned from plant debris and the soil is deeply loosened. Shrubs affected by the fungus are sprayed with a 1% solution of blue vitriol or Bordeaux mixture in mid-autumn. The procedure is repeated in early spring, before the leaves bloom. Buds are treated with Topsin-M, Previkur with the addition of any biostimulant (potassium humate, Appin, Heteroauxin).

During the vegetative season of the bush every two weeks sprayed with infusion of colloidal sulfur or wood ash. If the disease manifests itself during fruiting, when the use of any chemicals is excluded, to combat it use fungicides of biological origin - Fitosporin-M, Gamair. The concentration of the solution and the frequency of treatments is determined by the manufacturer's instructions.

Disease septoriosis (white spot) of black currant

The causative agent is a fungus of the genus Septoria. As well as for other fungal diseases, the most suitable conditions for the development of white spot - high humidity, low light, thickened planting. Brown spots appear on currant leaves (2-3 mm in diameter), which become lighter in the center by the middle of summer and become brown at the edges.

Infected leaves and shoots must be removed, then treated with 1% Bordeaux liquid. For prevention, you need to conduct annual pruning of bushes, dig up the aisles, in the fall to remove fallen leaves from the site.

What to spray on the moth?

Gooseberry moth - butterfly with wingscovered with black and yellow spots. Usually, she prefers gooseberries, but she also wants to eat currants. Laying eggs from the back of the leaves.

Emerging caterpillars devour the leaves from all sides. In the middle of summer, they turn into pupae and are hung along branches.

For prevention you need:

  • carefully clean and cultivate the land
  • collect all the pupae in July and destroy,
  • process urea in the fall,
  • spray plantings ("Fitoverm", arsenic calcium DDT and others).
For the treatment of currant from moths need to spray the bush Fitoverm, arsenic acid calcium DDT

Processing and spraying bushes in the fall with chemical and folk remedies

Processing currants in the fall carried out in order to get rid of various pests and diseases. After all, with the onset of spring, all microorganisms come alive and begin their vigorous activity.

In order to protect the currants from pests and diseases, a number of activities are needed during the autumn:

  • doing autumn digging around the bushes,
  • destruction of fallen leaves
  • pruning damaged, weak and old branches,
  • preventive spraying.

For preventive spraying Experts recommend the use of chemical solutions, which include drugs from pathogens and pests.

When spraying red and black currants must adhere to the recommendations:

  1. The procedure is best done in cool weather. In warm temperatures, parasites and pests multiply faster.
  2. The optimal is the holding of 2 procedures with a break of 10 - 14 days.
  3. Before spraying, release the plant from the sick and old parts. Deleted items destroy.
  4. To enhance the immune system of currant bushes is recommended to make mineral or organic fertilizers.

We struggle with diseases and pests of currants without chemicals:

Timely care of currant bushes, their treatment from pests and diseases - pledge of growing a healthy plant over the years and getting a good harvest.
