Plaque on gooseberries, what to do. White coating on gooseberries

Pathogenic microflora affecting berry bushes most often negatively affects the productivity and quality characteristics of the crop being formed. In very difficult cases, diseases may well cause the death of the plant.

Fungal infection is accompanied by the appearance on the berries of a very quickly spreading grayish-white coating, which after some time acquires a pronounced brownish tint. The fungus is perfectly adapted to severe Russian frosts.

The disease spreads through the foliage, stems and fruits of the bush

How to fight

Treatment of bushes should be carried out in early spring at the stage of active flowering and a week and a half after the plant has flowered. For this purpose, a mixture prepared on the basis of 150 g of copper sulfate, 200 g of lime and 5 liters of water is used.

Gooseberry anthracnose

A fungal infection that affects gooseberry foliage and causes the appearance of small, vague spots of a dark brown color on them. On a diseased plant, the yield decreases, and the growth of young shoots is also reduced.

The disease is characteristic of currants and gooseberries and manifests itself equally on both plants.

Control measures

In addition to burning fallen leaves, it is necessary to remove leaves affected by the fungus from the plant, and then spray the above-ground part of the gooseberry bush with a solution based on copper sulfate (20 g per 5 liters of water).

White spot or septoria

It is characterized by the ability to infect a wide variety of garden crops, causing the appearance of small and even round spots of off-white or brownish color with a dark border on the leaves.

The causative agent of the disease is a fungus of the genus Septoria

How to fight

When the first signs of the disease appear, all infected leaves must be removed and disposed of. At the initial stage of flowering, it is necessary to carefully spray the branches of the bush with a 1% solution of Bordeaux mixture.

Glass rust

The leaves of the bush affected by a fungal infection become deformed, wither and dry out prematurely, after which they fall off. In the absence of therapeutic measures, after some time the entire plant dies.

Appears on flowers, ovaries and leaves

Control measures

Sanitary pruning of branches followed by treatment of the plant with special fungicidal preparations “Abiga-Pik”, “Topaz”, “Bayleton”, “Hom” or a standard solution of Bordeaux mixture.

Gooseberry mosaic

Viral infection is accompanied by the appearance of a yellow peculiar pattern along the veins of the leaves, a stop in the plant's growing season, the formation of small and wrinkled young foliage, and the absence of berries.

The disease cannot be treated

Control measures

The main condition for maintaining the health of plantings is timely prevention of disease and destruction of aphids. Diseased bushes must be uprooted and then burned outside the site.

Scab

Microscopic fungi and bacteria cause the formation of brown spots on foliage, ovaries and branches, the appearance of green and brown growths on fruits, leaf fall, peeling on berries and their deformation.

A dense brown film on the fruit is a sign of severe infection

How to fight

Treatment of the above-ground part of the plant with the biological preparation “Fitosporin-M” before and immediately after flowering, as well as at the beginning of crop formation, in order to destroy fungi and increase the immunity of the bush.

Mold

Gray rot appears on gooseberries quite rarely. In the first stages, the disease affects the shoots from below, after which it causes massive rotting of the berries and complete or partial loss of the harvest.

May appear in wet weather if the gooseberry bush is too thick

Control measures

Treatment of the plant with a low-toxic, broad-spectrum drug “Fundazol” immediately before flowering, as well as immediately after the final harvest.

Gooseberries turn yellow

In addition to seasonal changes, as well as weather phenomena, insufficient moisture and nutrients, the yellowness of berry crops can be caused by certain diseases, including spheroteca and verticillium.

Symptoms may include: malnutrition or dangerous diseases.

What to do

Follow the rules of agricultural technology, timely irrigation measures, and regular fertilizing. To combat pathogenic microflora after harvesting, the shrub is additionally treated with the drug “Isofen”.

The berry falls

Too much drooping of gooseberries can be caused not only by natural reasons, including excess moisture and lack of nutrients, but also by certain diseases, among which powdery mildew is the most common.

Falling gooseberries may also indicate insufficient watering.

Control measures

Compliance with agricultural technology, timely irrigation measures, regular fertilizing. Preventive treatment with a mixture based on 150 g of copper sulfate, 200 g of lime and 5 liters of water.

The main pests of gooseberries and their control

Aphid

Small, sedentary insects of black, dark brown or light green color are distinguished by rapid reproduction, causing curling of shoots, as well as the appearance of honeydew and a large number of ants on the leaves.

Plants affected by gooseberry aphids develop slowly in the next season

For control purposes, it is necessary to treat the aerial parts of plants with special preparations “Fufanon”, “Bi-58”, “Aktara”, “Aktellik” or “Arrivo” and “Inta-vir” in accordance with the instructions supplied by the manufacturer.

Caterpillars

Gooseberry leaves are attacked by several types of caterpillars, among which the most common are moths, sawfly larvae and moths. The pest damages leaves and shoots, eats away all the internal parts of berries and flowers.

One of the most unpleasant bush pests

At the stage of swelling of the buds, the drug “Inta-Vir” is used. Repeated treatment can be carried out if pests are detected. In conditions of mass destruction, it is recommended to use the Iskra-M product.

An insect disguises itself as a wasp

Treatment requires urgent treatment with chemicals or bioinsecticides, which include “Bitoxibacillin” (80–100 g/10 l), “Dendrobacillin” (30–50 g/10 l) and “Lepidocid” (30 g/10 l). l).

Mite

The pest appears on the plant in early spring, settling on the underside of the foliage, which is abundantly entangled in cobwebs. The insect feeds on the juice of the berry crop, as a result of which the leaves turn yellow and gradually die.

Despite its small size, the insect can cause serious damage to the bush.

Control measures: the aboveground part of the bushes is carefully treated with a fungicide of inorganic origin. You can prepare a spray solution yourself based on 5 g of colloidal sulfur and ½ liter of water.

Gooseberry processing

The effectiveness of all preventive measures and therapeutic treatment of berry crops directly depends on the correct choice of product, as well as compliance with the method and scheme of its use.

The listed products may not be used at all stages of the gooseberry growing season, but these products show the highest efficiency and most often have a combined effect.

Diseases and pests of garden gooseberries often cause not only a reduction in the yield of the berry crop, but can also cause the death of the bush, so it is important to detect the damaging factor in time and choose the best method of control.

Stable, unpretentious, productive, our favorite berry bush - gooseberry - sometimes suddenly becomes covered with mold. Over time, the bush weakens, stops growing, the berries become sick and fall off. At this time, the gardener begins to ask himself the classic question - what to do? To answer it, you need to know what disease struck the wonderful gooseberry.

What diseases do mold cause?

First of all, you need to figure out what disease causes mold on gooseberries. Unfortunately, there are several such diseases. Berries become moldy due to the following fungal infections:

American powdery mildew (spheroteka);
European powdery mildew;
gray rot of berries;
glass rust.

Spheroteka

American powdery mildew or spheroteca has a characteristic feature at the beginning of its development. It appears after the gooseberry blooms. Leaves, berries and young shoots are covered with a white powdery coating, similar to mold.

At first it is easy to remove by hand. The fungus grows rapidly and changes color from white to brown. It is no longer washed off from the affected parts of the plant. The berries stop growing and become mummified. Young shoots become crooked, lag behind in growth and finally dry out. After 2–3 years, the gooseberry bush also dies.

Powdery mildew (European)

European powdery mildew initially looks like spheroteca. A white powdery coating appears on the leaves and shoots. The difference is that the disease begins in the second half of summer, rarely affects gooseberries, and the coating does not change color. The white color of the mold can be rubbed off with your fingers and always remains whitish. Under the influence of the fungus, the leaves turn yellow and fall off, and the shoots dry out.

Gray rot

The fungus only affects the berries; they simply dry out on the branches. During rainy summers, fungal spores grow through the skin of the berries and they become covered with a smoky gray coating. Fortunately, the disease rarely affects gooseberries.

Glass rust

If the gooseberry grows in a damp place where sedge is a weed, it will soon begin to become covered with bright orange rust spots. The fungus attacks leaves and berries in early summer. The mold on the berries is rusty in color; by mid-summer they fall off along with the dried leaves.

In addition to the diseases described, gooseberries are often affected by diseases in which the foliage becomes covered with:

brown;
gray;
black spots;
black soot.

These diseases are also caused by fungus, but they do not cause mold.

Causes of the disease

The culprits of infection with fungal diseases can be various reasons:

warm and damp summers;
too dark or low-lying landing site;
excessively wet location or rainy season;
infection from plants, insects, humans and wind;
thickening the bush with old shoots or a large number of new shoots;
excess nitrogen fertilizers in wet summers;
the growth of weeds, which are carriers of many diseases.

A weakened plant can hardly tolerate unsuitable climatic conditions, as well as violations of agricultural practices. While a strong and healthy plant is rarely attacked by pests and resists various infections for a long time.

Mold control

To get rid of spheroteca and other fungal diseases, the bushes and the ground under them at the end of the season are sprayed with a 3% solution of iron sulfate. On treated bushes, all young shoots, leaves and dried berries are cut off, collected and burned. In the spring, gooseberries are again treated with iron sulfate, and then with a soda solution. This double treatment gives very successful results.

Treatment with special means is carried out several times until the bushes are cleared of fungus.

The application of nitrogen fertilizers provokes the development of the disease. Fertilizing with phosphorus and potassium fertilizers, on the contrary, helps gooseberries cope with mold. Gardeners have developed many techniques for treating fungal infections.

An infusion of ash not only helps to get rid of fungus, but is also an excellent fertilizer. A kilogram of ash is poured into a 12-liter bucket, left for 3 days, filtered and watered the bushes. It is good to add liquid soap to this infusion for better adhesion to the leaves.
Liquid mullein has always been an excellent tool for feeding and disinfecting plants. Take 1 part mullein to 3 parts water, leave the mixture in the shade for three days, filter, add water to the volume of the bucket and water the diseased bush.
Kefir or sour milk is diluted with water in a ratio of 1:9. I treat the bushes with this solution even during flowering; it is harmless to bees.
During the onset of the disease, we get rid of fungi using a milk solution: 1 liter of whole milk is diluted in a bucket of water and the bushes are watered. The solution has an alkaline environment, which inhibits the development of fungi.

Treatment with any remedy for mold, that is, fungus, must be repeated several times until the gooseberry is completely cured.

With the widespread release of fungicides for use in private gardens, the question of how to get rid of fungal infections no longer arises.

If the branches do become covered with mold in the summer, then a variety of chemical and biological preparations can cope with all known diseases. The most popular were:

Topaz;
Fitosporin-M;
Nitrophen;
Fundazol;
Oksikhom;
Strobe.

These drugs should be used if the disease persists. They are used four times:

before flowering;
after flowering;
after picking berries;
2 weeks after the third application.

Resistant varieties

There have been big changes in gooseberry breeding recently. Breeders add new characteristics to new varieties:

thornless;
large fruit;
resistance to major diseases.

Resistant varieties include:

Beryl is a popular variety, zoned for Western Siberia. Sweet, yellowish-green berries grow on purple shoots. The yield of the variety is good. Thorns grow only from the bottom of the bush. Powdery mildew is not affected.
Vladil (Commander) is another very popular gooseberry variety, zoned for the Ural region. Sweet and sour cherry berries contain a lot of sugars and vitamin C. They do not suffer from powdery mildew.
Cossack is a new variety for the Central Black Earth region. Dark red berries have an excellent taste. Very high yielding. Resistant to powdery mildew.
Senator is a gooseberry from the Ural region with very tasty red berries. Not affected by powdery mildew.

In addition to varieties that do not suffer from spheroteca, there are many varieties that are resistant to this disease:

African;
Malachite;
Russian;
Harlequin;
Stanichny.

Mold prevention

Some agricultural practices will help prevent mold damage to gooseberries:

choosing a variety resistant to fungal diseases;
purchasing seedlings from trusted nurseries;
selection of the right place for planting;
preventative during the season;
weed removal;
proper preparation of the bush for winter.

Preventing fungal infections starts with choosing the right planting location. Since its appearance in Russia, they have been trying to plant it in well-lit and heated places. Planting should be protected from blowing winds, but stagnation of cold air should not be allowed.

Planting in a dark, damp or damp place is absolutely contraindicated.

The soil under the gooseberries is loosened until the buds open, and covered with a thick layer of mulch or black film. Branches and shoots must be treated with fungicides (Karate, Parachute, Bi-58, Danadim) if the bushes were affected by mold last season.

Instead of purchased products, you can use:

infusion of ash;
soda solution;
liquid mullein;
herbal infusion;
boiling water.

Before flowering, the branches and the ground under the bush are sprayed with a Strobi-type fungicide. If insect pests are noticeable on gooseberries, in addition to mold, then insecticides are used:

Karbofos;
Actellik;
Kinmiks.

After harvesting the fruits, the fight against diseases begins again with the help of the drug Strobi, with pests - with Karate and Karbofos.

In autumn, all fallen leaves are removed, sanitary pruning is done, all organic residues are removed and burned. You should not leave dried leaves, spider nests, or branches with traces of fungi or pests.

The soil under the bushes is dug up, spilled with disinfectant and covered with organic mulch.

You should not hope that the fungus will dry out from the heat or freeze in winter from the cold. The spores are very persistent and cannot be eliminated without appropriate treatment.

Conclusion

How to deal with the disease if mold appears on the gooseberries? By following correct agricultural practices, feeding and watering on time and in moderation, and protecting the bush at the onset of the disease, you are unlikely to ever have to remove your favorite gooseberry bush from the garden.

A gray-white coating that appears on gooseberries is a sign that the plant is infected with a dangerous fungal viral infection - powdery mildew. An uninvited “guest” came to us from America. The disease is spreading rapidly throughout the culture. Over time, the white color becomes gray and even acquires a brown tint. Adaptation to harsh winters contributes to the survivability of viruses. They survive our frosts on damaged bushes, so that with the onset of spring they can reproduce again with spores that fall on nearby plants. When you detect the first signs of powdery mildew, you need to know what to do with fruit crops and what control measures to use.

Dangerous fungus

The fact that gooseberries are healthy and a storehouse of vitamin C is known not only to humans. Powdery mildew also “knows” about this. Microscopic spores of the fungus are carried by the wind, along with birds and insects. They settle on raspberry, yoshta, and currant bushes. In the last ten days of May, the pest is detected on green shoots by the characteristic white coating - the initial stage of infection. These are myceliums. Given the rapid reproduction, the fight against powdery mildew on gooseberries begins immediately after the first symptoms appear, before the fruits have formed.

Warm spring days with rain create comfortable conditions for spore reproduction. If the bush has been infected since last year, the spores were not destroyed and overwintered safely, then in the spring, most often, the spread of powdery mildew begins from the lower branches. The leaves, and then the fruits, covered with a white coating over time have an unattractive appearance of rust with a hard crust that is difficult to clean. The leaf plates become deformed, curl, and stop developing. The young growth on the bushes dries out.

"Weak points" of powdery mildew

Like any pest, powdery mildew is “afraid” of chemicals. All preparations in liquid form are applied by spraying three times during the development period: in the spring, before the onset of active growing season, when the first flowers appear and another week and a half after the start of flowering. Moreover, for preventive purposes, neighboring plants also need to be treated with chemicals.

The lesions are already in a critical phase - the fruits cannot be consumed, and the bush must be treated with aggressive chemicals

Attention! Proper irrigation of plants should be carried out with a sprayer with a wide-spectrum sprayer. In this case, the liquid is applied to the crown and to the soil in the root zone. Particular attention is paid to the seamy (shadow) side: under the branches, on the back of the leaves. The plant is conventionally divided into zones and irrigated in turn: “top”, “sides” and bottom of the bush, capturing the soil around it.

Among the available and inexpensive means is. It is dissolved in an amount of 100 g in 10 liters of water. Spray at the beginning of the growing season.
A good result during the flowering period from treatment with a solution of sodium carbonate. For 10 liters of water you will need 50 g of soda ash.
The solution also has a good effect (0.2 kg of the drug and 10 liters of water at room temperature). Apply before buds open.
You can get rid of powdery mildew on gooseberries with the appearance of buds if you spray their branches with the composition. It is sold in specialized stores or prepared independently. Bordeaux mixture for powdery mildew on gooseberries is used at 3%. For preparation you need to take: copper sulfate (copper sulfate) - 0.3 kg, lime - 0.4 kg, water - 10 l. First, the vitriol is dissolved in 1 liter of water. Then, after the salt has completely dissolved, another 5 liters of water are added. The resulting saline solution is gradually poured into the lime solution. Stirs well and filters. The result should be a rich blue Bordeaux mixture.
Copper-containing preparations against powdery mildew on gooseberries: Gold, Ridomil Thanos, etc.
A proven remedy for powdery mildew on gooseberries is potassium permanganate (KMnO4). A weak solution prepared from 1.5 g of the drug per 10 liters of water is applied to the gooseberries twice: before flowering and again after 10 days. The drug Topaz is used for the same purposes.
Crystals of permanganate salt (2 tablespoons) are diluted in water (10 l). The mixture is heated to 90°C. The branches of the plant, as well as the soil under the bushes, are irrigated with hot mixtures until buds form for the purpose of prevention.
In the retail chain you can purchase chemical-based preparations that kill fungus (fungicides): , Skor, HOM, Abiga-Pik and others. When preparing the solution, you must strictly follow the instructions.
Fitosporin has a good effect. This is a complex effect on the fungal and bacterial environment of the drug, especially in the soil litter. It's all about. preserved live bacterium Bacillis subtilis, which does not die even at –20 or +40 °C. The fruits and soil are treated both before planting and during the fruiting period.

Physical and agrotechnical measures

Treatment with copper sulfate - as a way to prevent powdery mildew

When the snow melts, all the foliage that overwintered under the bushes is burned along with the spores.
The gooseberry is inspected regularly. Pruned at the first appearance of infected branches. This should be done on the eve of winter and with the onset of spring. All trimmings are burned, or they need to be buried outside the boundaries of the garden.
In a critical situation, when none of the treatment methods helps, you should act radically: uproot the infected bush and burn it.
The most effective way to get rid of the pest is to plant varieties of fruit crops resistant to powdery mildew: “Finnish”, “Harlequin”, “Houghton”, “Kolobok”, etc.

From folk repositories

Folk remedies in the fight have a gentle effect on the plant itself and on the future harvest.

Ordinary household compounds, food additives or medications in our home medicine cabinets will help get rid of the pest without resorting to radical measures.

Gooseberries are one of the most common plants in our region, producing a rich harvest of delicious fruits filled with vitamins and saturated acids. But, like any other plant, it is often affected by various diseases, including very dangerous ones, such as powdery mildew. Today we will talk about the most effective measures to combat the unpleasant white coating on gooseberries and when to spray it.

Powdery mildew: general information, main symptoms

Powdery mildew is an extremely dangerous fungal disease for gooseberries, the causative agent of which is several types of fungus. The danger of this disease is that the damaged plant not only loses its decorative appearance, but also becomes practically incapacitated: the parts of the plant affected by the disease turn black and die, and the inflorescences do not form ovaries. The disease has a negative effect even on those plants that were only slightly affected by it: shoots and buds will become less resistant to cold, which will lead to their complete freezing with the onset of winter.

Most often, the disease manifests itself in early summer, when spores emerge from the fungus. The rapid development of this disease is facilitated to a large extent by hot weather with a lack of precipitation and the presence of sharp temperature fluctuations. Powdery mildew spores are spread by wind or water splashes when watering gooseberries and even when a diseased plant comes into contact with a healthy one.

Powdery mildew on gooseberries

You can recognize powdery mildew by the following signs:

A white, loose coating appears on the leaves, shoots and even fruits of gooseberries, which looks like a layer of flour. Over time, it turns into a yellowish-brown film, which dries and becomes a crusty, dense formation. It is worth noting that the disease appears extremely rarely on gooseberry leaves (this picture is more often observed on currant bushes).
The fruits of the plant begin to change their shape, gradually decrease in size, stop developing and eventually simply dry out.
Gooseberry shoots begin to bend, their ends darken and gradually die, and the leaves curl and dry out.

Advice. Powdery mildew develops on gooseberries at an incredible speed, so it is necessary to carry out a set of measures to destroy it when the first symptoms appear, otherwise it can destroy not only the affected plant, but also spread to nearby ones.

Methods to combat the disease

When symptoms of the disease appear, the first step is to destroy the parts of the gooseberry affected by the disease, and only then begin to treat the plant with chemicals or natural solutions (at your discretion). Below are some of the most effective methods of combating the disease.

The best folk remedies

There are many recipes for “resisting” powdery mildew; we will look at a few of the most effective:

To create the solution we will need about 3 kg of wood ash and a bucket of water. The ash is poured with very hot water and infused for 24 hours. After this, the solution must be filtered and the bushes treated with it before flowering begins and after it ends. The procedure is repeated several times until the signs of the disease completely disappear at intervals of a week. Keep in mind that each gooseberry bush will require about 3 liters of solution.
Fermented grass. To create it, we need ordinary garden weeds and water. So, the weeds previously pulled out from the garden need to be finely chopped and then poured with hot water. We use approximately 5 kg of weed (half a bucket), then fill it to the top with water. Mix everything thoroughly and leave to brew for several days. Before processing the plant, the infusion must be filtered through cheesecloth. It is advisable to spray in the evening.

If you don’t want to use chemicals, try folk remedies

Mullein can also be an excellent gooseberry treatment. To prepare it you will need fresh mullein and water. Pour the mullein into a bucket (1/3 is enough) and fill it to the top with cold water. Let it brew for several days (2-3 days will be enough). Don’t forget to stir the infusion periodically and strain before spraying.
Oddly enough, even dairy products can help get rid of powdery mildew. Homemade or store-bought fermented milk whey is suitable for these purposes. To prepare the solution you will also need water. Its amount should be 10 times the amount of whey. The composition must be thoroughly mixed until a homogeneous consistency is obtained. The finished mixture is used to periodically treat the plants until they are completely cured.

Chemicals

Among the variety of chemical preparations for treating gooseberries against powdery mildew, perhaps the following can be distinguished:

Copper sulfate is a magical remedy that helps cope with the spread of the disease. Copper sulfate and water are used to prepare the product. 100 g of vitriol is enough for a bucket of water. Gooseberry processing is carried out in early spring until the buds have blossomed - not only the bush itself should be processed, but also the soil under it with last year's foliage.

Advice. You can try to reduce the amount of vitriol by replacing it with laundry soap. So, instead of 100 g of copper sulfate for a ten-liter bucket, we only need 1/5 of it, to which we add 150 soap. Dissolve the soap, previously thoroughly crushed. Separately, dissolve copper sulfate in warm water, which is then carefully poured into a solution with soap.

A drug called “Topaz” is incredibly popular among experienced gardeners. Spraying with the drug is carried out in two stages: before the beginning of the flowering period and immediately after its completion.
A drug called “HOM” is an excellent remedy (a kind of alternative to Bordeaux mixture). 40 g of the drug is enough for a bucket of water. You can prepare a combination preparation with the addition of some pest control agent. Everything is diluted separately in a small amount of water, and then combined and brought to the required volume with water.

Carry out preventive treatment so as not to lose the entire harvest later

Preventive measures

To prevent the possibility of gooseberry disease from powdery mildew, a number of simple preventive measures should be taken:

High-quality and timely pruning of bushes in the autumn-spring period. This will allow the formation of a healthy and developed plant, and it is one that can resist various diseases, including powdery mildew.

Advice. When carrying out the pruning procedure, it is important to remove damaged or diseased branches, which are either destroyed or buried in the ground away from the place where the gooseberries grow.

In the spring and summer (that is, during the period of active plant growth), you should carefully monitor the appearance of affected branches on the bushes. Their timely removal will increase the chances of preventing the development of the disease. It is believed that the spores of the fungus that causes the disease overwinter on gooseberry shoots and fallen leaves. Therefore, it is also important to remove it in the spring.
With the arrival of spring, when there is no more snow and the temperature does not drop below zero, you can give the gooseberries a “shock shower” (the main thing is to do this before the buds swell) using very hot water. You can add a little potassium permanganate or soda (a couple of teaspoons will be enough). Oddly enough, such a procedure is an excellent preventive measure against many diseases.
To increase gooseberry resistance to powdery mildew, feed the plant with fertilizers containing phosphorus and potassium, but avoid nitrogen.

As you can see, even though powdery mildew is a serious disease, it is quite possible to fight it, and even without negative consequences for the plant itself. Follow the tips presented in the article, and you will be able to grow healthy gooseberries that will delight you with a rich harvest. Good luck!

Powdery mildew on gooseberries: video

White plaque on gooseberries: photo

Seeing gooseberries and white coating on the berries, gardeners, faced with this problem for the first time, give up in bewilderment. Yes, it's a bush disease called powdery mildew. At first, the coating is less noticeable: an almost invisible “frost” is visible on the berries and leaves. These are spores of a fungal disease that grow and infect the plant more and more. If the bush is not treated, the white coating becomes more and more expressive and collects into whole fluffy flakes, affecting the berries and leaves. Then it changes in color - it becomes brown with black dots (fruiting bodies of mushrooms). The bush begins to lose its shoots - they dry out, the berries fall off. The following summer, the disease progresses even more as the spores multiply more intensely, and as a result the plant dies.

What to do if the gooseberry fruits are covered with a white coating of powdery mildew?

If, after examining the gooseberries, you notice a white coating on the berries only in the initial stage, you need to take the necessary measures to stop the development of the fungal disease. At the initial stage (as in our case), the best method is spraying. Active substances for this purpose can be ordinary laundry soap and copper sulfate. Take 20 g of copper sulfate and 150 g of laundry soap per 10 liters of water. It is better to dilute copper sulfate in not too hot water. Pour the thoroughly mixed mixture into the prepared soap solution in a stream. Laundry soap can be grated on a coarse grater. When spraying, special attention should be paid to areas affected by spores. To prevent the occurrence of the disease, it is advisable to spray the entire gooseberry (in this case, a white coating will not appear at all), as well as the soil around it.

Gooseberries by nature are an unpretentious shrub, but they need to be prevented against fungal diseases regularly, every spring. If we talk about currants, fungal spores often infect its leaves and young shoots, while gooseberries are damaged: they wrinkle, dry out and fall off. If the bush is neglected and your gooseberry is white, the coating on the berries is already clearly visible, you need to act immediately. All shoots heavily damaged by mushrooms should be cut off and burned. Do not be afraid that the bush will not give you fruit this year. But you will save him from an insidious disease - powdery mildew.

Prevention of the disease

To prevent plaque on the berries from appearing next summer, in early spring thoroughly treat the bush with the above mixture or use special ready-made preparations for spraying - “Cumulus”, “Tiovit Jet” or “Vectra”.
You can purchase them at any hardware store or supermarket.

For the purpose of prevention, start spraying the plant at the moment when the first young leaves appear. Treat the selected preparation not only to the young shoots, but also to the ground around the bush itself. The second spraying should be carried out during the flowering period, the third - during the formation of the ovary. When the berries ripen, use more gentle preparations for prevention.

how to process gooseberries. A white coating has appeared on the gooseberries. How can you treat the bush to get rid of mold?

Powdery mildew is a type of fungal disease. Mushrooms have one peculiarity - where one type of mushroom grows, there is no place for another - the ecological niche is occupied. In order not to fight the disease, it must be prevented or eliminated by planting other, but harmless, mushrooms on the gooseberries in advance. They are always found in mullein or goat manure. In late autumn or early spring, we cover the gooseberry bushes with a thick layer of fresh manure along the entire perimeter of the crown. And when the leaves come out, you can pour mullein or goat infusion directly over the leaves. Gooseberries are a wonderful feeder and don’t get sick in any way. The harvests are huge and it reproduces easily. We grow the kolobok variety - it has no thorns. Sweet, tasty, productive and easy to collect and not painful.

Try phytosporin, these are natural bacteria. not chemistry. works great against all fungal infections, rot and mold, and you don’t have to treat it like vitriol all summer long

I got rid of the white coating on the berries this way: 7 ml bottle of iodine per 7 liters of water, spray the bushes.

If you start with chemistry, you will continue to process it all the time,

because powdery mildew will periodically return,

if the variety is unstable.

Try Fitoverm, as Elena advises.

Feed heavily with potassium-phosphorus fertilizers,

mulch the soil with rotted straw

(bacillus hay, the enemy of powdery mildew, grows on it).

The bushes should not be thickened.

It is better if such unstable varieties grow in the sun.

Every autumn we prune old shoots. and everything is fine

In winter I pour boiling water over the bushes, in the spring I treat them with Acrobat, and in the summer, if necessary, with Fitosporin.

A matchbox of soda ash + a quarter of a piece of laundry soap in a bucket of water. We process until the buds open for the first time, then every 10-14 days until flowering, and the last time when the fruits set. Pick off diseased fruits and burn them, and severely damaged branches too; they will dry out anyway.

Powdery mildew is a fungal disease. It appears when the bush is poorly heated and has high humidity. Processing needs to be done.

Measures to combat gooseberry powdery mildew: spray with fungicides. Before the buds open, gooseberry bushes and the soil underneath are sprayed with a solution of nitrafen (eradicating spraying). Or you can treat the bushes with a 3% solution of iron sulfate (30 g per 10 liters of water) or 1% solution of copper sulfate (10 g per 10 liters of water).

it's called powdery mildew

This is a complete bummer and it is completely impossible to defeat him with anything. It’s better to buy a variety resistant to powdery mildew and plant

This is a mess for the gooseberries, nothing will help

Delete\. until powdery mildew crawled onto other bushes.

Powdery mildew. The variety is probably not resistant to powdery mildew, but hurry to throw away the bush, there are ways to get rid of it and what to do for prevention. Look in a search engine about much. dew on gooseberries.

Powdery mildew. It’s better to throw out the bush and not bother and cultivate the infection with your own hands. New varieties are resistant - look on the Internet or gardening magazines.

A gray-white coating has appeared on the gooseberries. Looks like powdery mildew, but the leaves are normal. What could this be??

American powdery mildew, treat with Fitosporin, Alirin, Gamair (biofungicides)

well, it’s either a disease, or someone sprayed your gooseberries...

It all starts with berries.

Treat twice with an interval of 7 days. In case of severe damage

The snow melted and, without waiting for illnesses, I sprayed the burgundy mixture. with copper sulfate which. the result is good.

Treat with Topaz. It helps a lot.

I have the same. First one bush, a year later the second. For two years I treated the bushes with everything - in March I poured hot water with potassium permanganate, then sprayed them with Bordeaux mixture, infusion of ash, Topaz, soda ash, etc. This year the berries are again covered in bloom, and the foliage is beautiful. I uprooted both bushes so that it wouldn’t spread to others. I will plant bushes that are not susceptible to powdery mildew, for example, “Emerald”.

There is a white coating on currant and gooseberry bushes, powdery mildew, methods of control

Alas, your plants are affected by powdery mildew. This year the disease has spread very strongly in the Moscow region, causing a huge

harm. The development of this dangerous disease is facilitated by high relative humidity and warm weather (17-28°C). Hot and dry weather somewhat slows down the development of the disease.

Now the white powdery coating has thickened, turns brown, and takes on the appearance of felt with black dots interspersed with it - fruiting bodies

mushroom. Berries covered with a felt coating become gray and inedible. Unfortunately, the time to fight the disease has already been lost.

But in the fall or next early spring, it is imperative to trim and burn the tops of the affected shoots.

Prevent the development of powdery mildew It is possible only in the initial stage of the disease, immediately when a white coating appears on the underside of the leaves. For

To eradicate foci of disease, plants should be sprayed in the fall or spring with the following preparations: 0.02% topaz 2-3 times with an interval of 10-15 days, or 0.02% Vectra (before and after flowering), or 0.2- 0.3% thiovit jet (only on currants!) after flowering.

Other means are also used: 1/3 of a bucket of mullein or rotted hay is poured into 3 liters of water, left for 3 days and diluted

water in a ratio of 1:3. Then the infusion is filtered and sprayed on the plants.

There is a folk remedy. Take 1 liter of whey, skim milk or buttermilk, add 9 liters of water and spray the bushes. In early spring, use an infusion of wood ash (300 g per 10 liters of water). Plants

sprayed 2 times with an interval of 10-12 days. You can add dry wood ash to the tree trunks of bushes (300-500 g for each bush), mixing it with the soil.

If you plant varieties of currants and gooseberries on your plot resistant to powdery mildew, then there will be no hassle.

White coating on gooseberries and currants, what is it?

This disease is powdery mildew.

This is a disease of shrubs. Powdery mildew is dangerous for gooseberries and currants. The disease manifests itself on shoots, leaves, and fruits. The fruits are covered (and the shoots and leaves too) with a dense gray or white coating that does not wash off.

Last year I tried treating it with phytosporin. And this year it’s the same picture again. What to do? should I remove the bushes?

Powdery mildew. It is necessary to treat.

Powdery mildew - useless to treat, remove

powdery mildew fungal disease

Powdery mildew affects many crops. It also happens on weeds. It is better to grow resistant varieties, especially for gooseberries and currants. To eradicate, try leaving yourself without a crop for one year, but conducting a very active fight. So to speak, eradicate the reptile. But more often, unfortunately, the plantings have to be replaced. I bought 2 bushes of a resistant variety and propagated them. Now there are no such problems.

In early spring, before flowering, you need to spray it with “Topaz”, it helped my gooseberries.

A white coating appears on gooseberries, like mold. What is it and what can you spray it with?

A white coating appears on the gooseberries, like mold... what is it and what can I spray it with??

Most likely it is powdery mildew. Last year I tried to treat currant and gooseberry bushes with a hot shower in early spring before the buds burst. I read that you can add potassium permanganate to the water. Before and after flowering, try the drug “Tiovit Jet”. You can also process “Hom” and “Topaz”. From ecological methods - infusion of ash. In general, new varieties of gooseberries are now being developed that are more resistant to powdery mildew. Last edited on March 14, 2016, 21:09

Tatyana, we water the bushes with hot water every year. Unfortunately, this did not help the gooseberries; all the berries were gone((.

Svetlana, and for gooseberries they write with potassium permanganate. I'll try it this year, I haven't doused it yet. We still have a lot of snow and the frost today is -6 C. In general, old varieties, no matter what you do with them, can still get sick. We refused them. A relative several years ago shared a good variety (green berries), and that was all they kept.

I think you're right. We need to change

It is necessary to spray with copper-containing preparations (hom or others) once every 14 days according to the instructions.

After flowering, treat with soda ash in a soap solution (take 50 grams of soda and 10 liters of water, enough soap to stick better). Soda ash was previously used to wash clothes. First, prepare a soap solution, dilute the soda separately in water, then carefully combine everything. If necessary, filter.

There is also a substance that is used in the food industry in the production of cheese and condensed milk, this is disubstituted sodium phosphate. It is also called disodium phosphate or food additive E339. This substance is used to combat gooseberry powdery mildew. And other powdery mildew mushrooms, for example, on zucchini and pumpkin. The powder is dissolved in water and three treatments are done after 7-9 days. At the same time, it is also a phosphorus fertilizer. To process gooseberries, 100 grams of the substance are diluted in 10 liters of water. The last treatment should be carried out 20 days before harvest.

Maybe these remedies are not so eradicative, but safer for humans. Last edited on March 15, 2016, 08:22

Why poison the garden with drugs when new immune varieties of gooseberries have appeared. There are many of them, they have been known for 50 years. No one in the world grows gooseberries that are not immune to powdery mildew. Change and only change.

This is powdery mildew. You can effectively escape from it if you spray it with Topaz, but it is better to do this right away when you see several of these berries (or leaves). If almost the entire bush is already affected, then Topaz will help little, and it’s unlikely that anything else will help.

How to treat brown coating on gooseberries?

Why do gooseberries become covered with a brown coating?

phytosporin, you can eat it even on the day of treatment, it is impossible to overdose on the concentration, several treatments (biologically a preparation from living bacteria)

powdery mildew.. too late to treat.. will not help

It seems like it’s already too late to treat, it’s powdery mildew, at the first sign (something in the form of white foam at the tips of the shoots) it was necessary to spray with 1% Bordeaux - this is due to temperature changes, thickening, etc.

They spelled it correctly - it is spherrotheca, American powdery mildew. Now there is nothing to save. Before the buds swell, it is necessary to treat with Bordeaux mixture or something like Topaz or Fundazol. Then a couple more times at intervals of 2-3 weeks. Then there is a chance that he will be alive and well. Be sure to process in the fall. This happens from thickening, from excess moisture, but the main thing is the variety! New varieties resistant to powdery mildew have now been developed.

your variety is not resistant to powdery mildew, it must be treated throughout the season from the moment the leaves begin to bloom, the last time in August after harvesting; it is easier to plant resistant varieties

You have IMPASSABLE DEBRES in the gooseberries, that’s why they “bloom.” Elisheva wrote to you about soap and baking soda. This WILL HELP, BUT, collect all the affected berries and burn them. Then treat the plants, treat the inside of the bushes well. They are not ventilated in your place, so there is STEAM and all sorts of fungi are happy about this and grow for their own pleasure. Afterwards, if there are branches affected by powdery mildew, they will look like they are burned, but it is better to remove them, they are weak and will only spoil the appearance. And the bushes need to be thinned out so that they can be ventilated by the wind.

you need to treat it in advance, for this there is Ridomil Gold, for example

soda ash and slurry will help you
