The gooseberries are covered with a brown coating. Main diseases and pests of gooseberries and their control

Already in mid-summer, white bloom and brown spots can be found on the leaves, stems and even berries of gooseberries. At the same time, fruit growth slows down, and damaged parts of the plant become deformed and twisted. All these are clear signs that the gooseberry has become infected with powdery mildew.

Spherotheca or powdery mildew is a fungal disease that actively develops on the plant throughout spring and summer. As a rule, the fungus affects the upper part of the leaf, the berries develop poorly, begin to crack and fall off.

Where does the fungus come from? If the summer is cool and rainy, this only accelerates the development of the disease; After all, high humidity promotes the rapid spread of fungus. But in dry and hot weather the disease progresses much less.

Let us add that this gooseberry disease most often affects tall varieties, which are also often subject to pruning. But low-growing varieties that are not properly cared for also often become covered with a white coating, which is sometimes called gooseberry mold.

Experts advise using special phosphorus-potassium fertilizers to prevent such diseases, as well as regularly loosening the soil under the bushes. If the disease is already progressing, then a white coating on the gooseberries indicates that the entire harvest may be lost. Therefore, even when the first signs of the disease are detected, you need to act as quickly as possible. In addition, powdery mildew is quickly transmitted from one plant to another, and even to other crops. And you shouldn’t be surprised that after a while a white coating will appear on the currants.

So, the gooseberries are covered with a white coating, what should you do? First of all, it is worth saying that it is necessary to grow varieties that are resistant to powdery mildew whenever possible. But if the gooseberry disease is already progressing, to combat it it is necessary:

fight the wintering form of the disease;
treat the bush with special preparations three times a year;
increase gooseberry resistance to diseases.

Now we’ll tell you how to fight the fungus in more detail. The fight against wintering infection consists, first of all, in removing damaged shoots and berries from the bush and destroying them. In addition, in the fall, for the purpose of prevention, shoots should be pruned to healthy tissue. And the soil under the plantings must be regularly dug up, fallen leaves destroyed, and the soil loosened.

All this will help curb the spread of the disease. Experts also advise, in early spring and late autumn, to treat bushes with a solution of copper sulfate. Or you can simply scald the leaves with boiling water - this is no less effective, but more dangerous.

If a white coating appears on the gooseberry every year, then spraying should be done regularly.

This processing is carried out as follows:

The first spraying should be carried out before flowering using fungicides.
The plant is treated the second time after the bush has completely bloomed, with the same fungicides.
And no later than three weeks from harvest, subsequent processing is carried out.

How to treat mold on berries? The following drugs have proven themselves to be excellent: Cumulus, Vectra and Topaz.

Treatment of bushes affected by the disease can be carried out without the use of chemicals. There are also folk remedies that in certain cases can be quite effective, especially in the initial stages of the disease.

Let us add that treatments with all sorts of infusions should be carried out several times; and if it rains after treatment, then spraying must be repeated.

So, if the gooseberries are covered with a white coating, here’s what you can do:

treat the bushes with solutions of mullein and wood ash;
soap and soda infusion;
potassium permanganate solution;
onion peel;
sour milk and kefir;
horsetail;
tansy infusion.

How to treat gooseberries with folk remedies? Let's first prepare the ash solution. To do this, take one kilogram of wood ash, pour it with ten liters of warm water and leave for a week. Immediately before processing, the folk remedy is shaken. It is necessary to spray gooseberries with ash solution 4 times with an interval of 2 days.

If gooseberries are sick with powdery mildew, you can try to eliminate the white coating on the berries with mullein infusion. To prepare the latter, take one part of mullein, which is diluted in three parts of water. The resulting mixture is infused in a warm place for three days. The finished product is filtered, after which the bush can be processed.

If the gooseberries are covered with a white coating, then the plant can be sprayed with a soda solution. This substance is generally quite widely used in gardening work. After all, soda can effectively fight various fungi. The solution is prepared from 50 grams of laundry soap, 2 tablespoons of baking soda and 10 liters of water. However, gooseberries must be processed immediately after preparing this folk remedy; and it is best to do this before and after flowering.

If there is a white coating on the gooseberry bushes or the gooseberry berries are already covered with a white coating, then a manganese solution can also help. This product is prepared from 10 liters of water and 1.5 grams of manganese. Treatment for preventive purposes is carried out once a week, as well as after rain.

Many fungi die in an acidic environment, which is why sour milk, kefir and whey are effective against powdery mildew. Therefore, if a white coating appears on the gooseberry fruits or gooseberry leaves, then the bush should be treated with a solution of sour milk (9 liters of water per 1 liter of milk, kefir or whey). The solution must be shaken before use. Spraying is carried out in three doses at intervals of three days.

How else to get rid of white plaque on gooseberries? Try an infusion of onion peels - this remedy significantly improves the plant’s immunity. So, you can collect and store onion peels from used products in winter, and treat them with infusion of garden crops in spring and summer. To prepare the infusion you will need 10 liters of boiling water and 200 grams of dry onion peels. This product is infused for 2 days.

It is better to spray the plants three times:

before flowering;
during the period of berry formation;
after harvesting.

All activities for treating gooseberries with the preparations described above should be carried out only in calm weather. By the way, if a white coating forms or spots appear on the gooseberries, then other crops in the vicinity should also be treated. If this is not done, then they will become covered with mold from powdery mildew.

Fortunately, special fungicides have already been developed that can save the shrub if you start to fight the problem in time. In this article we will talk about what to do if a brown coating has formed on the gooseberries: what this may be associated with, and how to treat it.

In general, plaque on gooseberries may indicate several serious diseases at once. If we talk specifically about brown plaque, then this is a clear sign of the most dangerous and common gooseberry disease - powdery mildew.

Oddly enough, but among the people, this disease is more often called just white plaque. It turns brown at an advanced stage, when there is no point in fighting the disease, and the bush must simply be removed and destroyed outside the garden plot.

In general, powdery mildew can be of two types - American and European, and their external manifestations are similar, and the diseases differ only in the type of fungus that causes them.

The first symptoms of the disease can be detected in the spring or at the very beginning of summer: a white coating appears on young shoots, which in the initial stages is easily erased even with your fingers. But, of course, you won’t get rid of the fungus this way. And soon the colony will completely move on to the ovaries and fruits of the plant.

Moreover, every day the plaque will become denser and denser, and its color will become darker and darker, until it becomes dark brown. And if treatment is not started on time, then after 2-3 seasons the bush will die completely, and the pores of the fungus will also scatter with the wind throughout the entire garden area, infecting other plants. Moreover, powdery mildew is not afraid of even severe frosts.

When dealing with powdery mildew or spheroteca, control measures must be the most serious, and not one-time, but permanent, including preventive. And here are the most effective methods of treatment:

Affected berries and infected parts of the plant are taken outside the site and destroyed.
In early spring, the shrub is treated with boiling water to kill fungal spores.
Fungicides are applied even before the first ovaries form. Bordeaux mixture or soda ash solution is used. Moreover, it is best to add a little laundry soap to the latter. Let us add that spraying with chemicals is usually carried out in the first half of the day.
In later stages of the disease, you can try using an infusion of wood ash, which can be used to treat both the upper parts of the bush and the ground parts (300 grams of dry mixture is diluted in 10 liters of water).
If the entire gooseberry planting is already affected, then you will have to use more powerful means - complex fungicides. Fitosporin, Topaz and Fundazol have proven themselves well.
Additionally, you can use organic fertilizers - mullein, bird manure or humus. They are diluted with water in a ratio of one to three. This feeding strengthens the bacteria that fight the fungus.
If powdery mildew has already been observed on the site, then experienced gardeners recommend purchasing and planting exclusively spheroteca-resistant varieties. So that you don’t have to wonder later if the gooseberries are covered with a brown coating, what to do?

Mold on berries and spots on gooseberries: other causes

As mentioned above, there are several diseases at once, due to which various spots appear on the gooseberries, and the fruits can become moldy. And in second place in frequency after spheroteca is anthracnose. This disease is also caused by a fungus, and plants are especially susceptible to it during rainy and warm periods.

First, white spots with a glossy structure appear on the gooseberry, which merge with each other over time. And after a while they also darken, and the entire bush acquires a brown tint. If you do not start treatment, then very soon the leaves will begin to dry, the appearance of young shoots will slow down, and the harvest will deteriorate and decrease.

For proper treatment, it is important not only to use chemicals, but also to remove infected parts and remove fallen leaves. And the most effective fungicide in this case is Bordeaux mixture, which is diluted with water in a ratio of 100 grams per 10 liters of water. The crop will need to be processed at least four times a season with an interval of fifteen to twenty days.

Rust

It is immediately clear where this name comes from - glass rust, because its main feature is a characteristic stain shape, bright orange color. Infection usually occurs in early spring, when the wind brings fungal spores. The foliage on the gooseberry becomes distorted, curls and falls off. And if treatment is not started in time, then rust will affect the fruits, which will also begin to deform and dry out.

It is believed that the most effective way to combat this disease is proper planting and prevention. Thus, it is recommended to plant only varieties with resistance to this disease. In addition, bushes growing in places with high humidity and near bodies of water are most susceptible to rust.

But if infection still cannot be avoided, then Bordeaux mixture will be an effective means of fighting rust - a solution that is already familiar to us: 100 grams per 10 liters of water. But this time the gooseberries are processed in three stages:

during the formation of ovaries;
immediately after flowering;
10-14 days after flowering ends.

Well, at the end, a few words about diseases typical of gooseberry fruits.

The leaves turn yellow, followed by the berries. The reason is the already familiar spheroteka or powdery mildew. If yellow spots appear on the leaves along the veins, then most likely the bush is infected with mosaic.
Mold on berries. The reason is the same - powdery mildew, but it can also be a sign that the bush is affected by a pest - aphids.
Berries and leaves fall. Almost all of the diseases listed above and many others can cause this. But there is another reason - perhaps there is a nitrogen deficiency in the soil or some macroelements are missing.
Scab is quite rare in gooseberries, but in the garden it is a common disease. At the same time, dark brown spots also appear on the plant - on the fruits and leaves. The bush should immediately be treated with a solution of Bordeaux mixture (100 grams per 10 liters of water) or a solution of copper sulfate (40 grams per 10 liters of water).

When growing any garden crop, there is a risk of infection with a number of dangerous diseases. For example, there are gooseberry diseases that, in the absence of the necessary treatment and prevention, can cause enormous damage to the crop and lead to the death of the plant. To combat them, fungicides of different effectiveness and methods of application have been developed, allowing you to save the bush at any stage of infection.

This is a common name, or rather, a sign of the most common disease of gooseberries and many other garden crops - powdery mildew or spheroteca. It is divided into two types (European and American), both of them have almost identical external manifestations, but differ only in the type of fungus that causes the disease.

Signs

The first symptoms of powdery mildew appear in spring or early summer, immediately after the bush blooms. On the young vegetative parts of the plant (usually on the lower side) a characteristic white coating appears, which has a loose structure.

In the initial stages of the disease, it is easily erased, so some gardeners mistake the infection for ordinary pollution. Gradually, colonies of the fungus spread to the gooseberry ovaries, fruits and cover most of the plant. The plaque becomes denser every day, eventually taking on a dark brown tint.

Against the background of the disease, the growth and development of shoots stops, and they become bent.

The leaves dry out, curl and begin to separate from the plant. Powdery mildew causes the greatest damage to the crop - the fruits stop growing, a strong coating appears on the berries, they burst and crack.

If treatment is not started in time, the infected gooseberry bushes die within two to three seasons, and the pores of the fungus are carried by the wind and insects to nearby fruit bushes.

Powdery mildew can persist on fallen leaves and branches even in the most severe frosts, and when the optimal temperature is reached, the disease is activated again.

Treatment

When spheroteca fungi are detected on a plant, the fight against them should continue throughout the season, but we must not forget about preventive measures.

There are many different effective treatment methods, the most common of which are:

All infected parts of the plant, including berries, must be taken outside the site and completely destroyed.
Even in early spring, it is necessary to treat the bush with hot boiling water, since high temperature kills the fungus.
It is recommended to use fungicides until the first ovaries form. Most often, Bordeaux mixture is used (a mixture of copper sulfate and milk of lime) or a solution of soda ash (50 g per 10 liters of water). To enhance the reaction and interaction with the bush, it is recommended to add 50 g of laundry soap to the solution. It is advisable to spray with chemicals in the first half of the day.
In later stages of the disease, an infusion of wood ash is used (300 g of dry mixture per 10 liters of water). This product can be used to treat both ground and upper parts of the bush.
If the entire planting of gooseberries and nearby plants are infected, strong complex fungicides should be used. For example, “Topaz”, “Fundazol”, “Fitosporin” and others.
As an additional measure, you can apply organic fertilizers, such as poultry manure, mullein or humus (in a ratio of 1:3 relative to water). After feeding, the vital activity of bacteria increases, which subsequently begin to feed on the mycelium of the spheroteca.

There are a number of gooseberry varieties that have increased resistance to fungal diseases, including powdery mildew. If a spheroteca has already been observed on the site, it is recommended to plant them.

Anthracnose

The second most common gooseberry disease, which is also a fungal infection. The onset of the disease usually occurs in mid-summer, especially during the rainy season.

First, the leaves of the plant are affected - small white spots with a glossy structure appear on them. Over time, they merge with each other, spread over the entire surface of the bush, acquiring a brown tint.

If the necessary control measures are not taken in time, the leaves begin to dry out and fall off, the appearance of new shoots is reduced, and the quality of the crop deteriorates.

Treatment

Anthracnose is highly treatable if you choose the right medications. It is very important to remove fallen leaves, trim already infected vegetative parts of the plant, and then destroy them.

Septoria (white spot)

It is a type of anthracnose, but the main difference is the type of fungus that causes infection of the bush. With this disease, characteristic small spots appear on the leaves, which have a grayish tint with a brown border.

As infection progresses, black dots form on the plaque, in which an increased number of fungal spores is noted. The disease causes leaves to curl and fall off. In advanced cases, septoria completely affects the entire bush, which leads to its complete drying out.

The same fungicides as for anthracnose are suitable for treatment. Plus, as a preventative measure, it is recommended to treat the soil near the gooseberries with a weak solution of potassium permanganate, boron or zinc. It is advisable to carry out the treatment twice per season - in spring and autumn.

Rust

There are several varieties of this disease, but gooseberries are most often affected by goblet rust. This is a fungal disease that affects the leaves of the plant.

It got its name because of the specific shape of the spots, which look like small glasses. In the early stages they take on a bright orange hue and are located mainly on the lower part of the leaves.

The peak of infection occurs in early spring, when the pores of the fungus are carried by wind and insects from the soil or other plants. As the infection progresses, the foliage becomes curled and distorted and then falls off. If treatment is not started, rust affects gooseberries. Affected fruits lag behind in development, become deformed and dry out.

Treatment

The most effective way to combat gooseberry rust is to follow preventive measures and planting rules. It is recommended to plant only those varieties that are resistant to the disease. Plus, the disease is more often observed when planting near bodies of water, as well as in lowlands and areas with high humidity.

These points should be taken into account even before planting the gooseberries.

If the disease cannot be avoided, rust responds well to treatment with a 1% solution of Bordeaux mixture (100 g per 10 liters of water). The treatment is carried out in three stages - at the moment of formation of the ovaries, after the start of flowering and 10-14 days after its end.

This is a viral disease that is the most dangerous for most fruit and vegetable crops. Gooseberry mosaic is a specific disease for this type of plant, so infection occurs through living organisms, as a rule, various herbivorous insects (aphids or mites), as well as after pruning the bush with an untreated instrument.

External manifestations

Some time after infection, a characteristic pattern of bright yellow or light green color appears on the leaves. The spots are always located along the leaf veins, so the disease is easy to distinguish even in the early stages.

As the disease progresses, the bush stops growing and new shoots and ovaries do not appear. New sheets are smaller in size and have slight wrinkles on the surface. Fruiting practically does not occur.

Gooseberry mosaic is practically untreatable, so if an infection is detected, it is necessary to dig up the diseased bush and destroy it. Further prevention of the disease plays an important role - treating the plantings with insecticides to reduce the number of insects, purchasing and planting new bushes to update the genetic material of this garden crop.

Berry diseases

Many diseases typical of gooseberries also affect the fruits of this plant, which significantly deteriorates the quality and quantity of the harvest. When identifying any symptoms, it is important to accurately identify the disease, since treatment methods differ in each specific case.

The most common signs of gooseberry diseases:

Appearance of yellowness. If leaves and berries begin to turn yellow, we are usually talking about powdery mildew or spheroteca. This disease affects fruits only in the later stages, so before yellowing appears, a characteristic white coating can be noticed. If the leaves have small yellow spots along the veins, the bush is probably infected with mosaic, an effective treatment for which has not yet been developed.
Mold on berries. This symptom is characteristic only of powdery mildew, but mold can appear due to infection of the bush by aphids. To determine the disease, it is necessary to carefully examine the entire bush for the presence of clarifying signs.
Fall of berries and leaves. Almost all diseases cause the shrub to dry out, followed by the loss of leaves and fruits. However, the cause may also be a lack of macroelements in the soil, for example, such a symptom is observed with nitrogen deficiency.
Scab, which is one of the most common plant diseases in the home garden, is extremely rarely observed in gooseberries. Despite the fact that the risk of infection is minimal, if dark brown spots characteristic of scab appear on the leaves and fruits, the planting should be treated with a 1% solution of Bordeaux mixture (75-100 g per 10 liters of water) or copper sulfate (40 g per 10 liters ).

Prevention

Competent preventive measures can significantly reduce the risk of the appearance and development of gooseberry diseases.

Prevention of infection comes down to a few simple measures:

All affected parts of the plant must be promptly removed and burned outside the site, since the fungus continues to live even in the dead parts of the gooseberry.
Next to planting berry bushes, it is recommended to plant plants that repel insects and pests that spread diseases. Garlic, onions, dill, marigolds and chrysanthemums have this property.
You should choose the gooseberry variety wisely, since some of them have increased immunity and resistance to a number of diseases.
Treatment should be carried out at least twice per season, regardless of the presence of the disease. For preventive purposes, you can use a solution of potassium permanganate, copper sulfate or Bordeaux mixture. If there is a disease, then you need to purchase strong fungicides with a complex effect, for example, Fitosporin. When choosing a drug, you should carefully read the description and dosage of the drug.
It is important to follow processing rules. The first application of the product should be no later than 14 days after the onset of the disease, and if it rains after using the fungicide, then the treatment of the bush must be repeated after 4-5 hours.
It is necessary to apply all the necessary synthetic fertilizers on time, since the lack of macroelements in the soil (nitrogen, potassium and phosphorus) directly affects the condition of the gooseberries.
To strengthen the protective forces of the bush and renew the genetic fund of the planting, it is advisable to plant new plants and prune old bushes every 3-4 years.

In order to notice the disease in time and take the necessary measures, it is important to regularly inspect the gooseberry bushes, paying attention not only to the upper part of the leaves, but also to the lower part. Timely treatment plays an important role, since the use of drugs is much more effective in the early stages of the disease.

Like other fruit and berry crops, gooseberries are susceptible to many dangerous diseases. Treatment of the disease depends on many factors - characteristics of the variety, degree and stage of infection, choice of fungicides for treatment. To get rid of fungal and viral infection of shrubs, you should follow preventive measures, regularly replant the plant and wisely choose a site for planting.

Seeing gooseberries and a 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 not only the young shoots with the selected preparation, but also 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.

The gooseberry fruits are covered with a white coating and are falling off. How can you save the fruits?

Dear namesake! Your gooseberries are affected by powdery mildew. This is a fungal disease. IN NO EVENT SHOULD YOU USE SULFUR TO COMBAT THIS FUNGUS, YOU WILL BURN THE PLANT. To combat powdery mildew of CURRANTS and GOOSEBERRY (but only on them), use a 0.5% solution of SODA ASH with the addition of 0.4% laundry soap. If the shoots are already damaged, they should be cut off and burned immediately. Don't doubt it, it's scientifically proven to help. You can trust me. Copper-containing preparations for powdery mildew do not help.

“Topaz” - 3-4 applications per summer, this is powdery mildew.

Most likely it looks like powdery mildew (although it seems a little early) But just in case, you need to spray the copper with preparations containing preparations. Or other drugs for powdery mildew

We need to treat the bushes.

All is not lost yet. Although this season you won’t be able to taste the berries.

Spray the bushes with Topaz. In general, it was necessary to treat with this preparation in early spring before the gooseberry ovaries.

Most likely, your shrub is affected by American powdery mildew. American powdery mildew is a dangerous fungal disease of gooseberries. It also affects black currants and, to a lesser extent, red and white currants. Affects leaves, shoots and fruits. In gooseberries, the berries are severely affected, in currants - fruit branches, stalks, and occasionally berries. Diseased parts of the plant are covered with a white powdery coating, which later becomes denser, becomes brown in color and looks like felt. Plaque forms on both sides of the sheet, but more on the top. Diseased berries develop poorly, many of them dry out, crack and fall off. The tops of the affected shoots darken, bend and die. The development of powdery mildew is promoted by high air humidity and temperatures from +17° to +28°C. Hot, dry weather inhibits the development of the disease.

To destroy an overwintering infection (overwintering spores), in the fall or early spring (before the buds open!), treat the bushes with a solution of copper sulfate (50-100 g per 10 liters of hot water). As soon as the vitriol dissolves in water, process it, this must be done within 2 hours. During the growing season, spraying is carried out before flowering and after flowering with topaz (2 g per 10 liters of water) with an interval of 10-14 days. Treatment with topaz is carried out no more than 4 times per season, the last (if necessary) - no later than 20 days before picking the berries. Spraying with soda ash and soap (50 g of soda + 50 g of soap per 10 liters of water) or a copper-soap solution (10 g of copper sulfate is dissolved in 0.5 liters of hot water. Separately, 100 g of soap is diluted in 10 liters of warm water. Solution) is effective. copper sulfate is poured in a thin stream with constant stirring into the soap solution. The prepared emulsion should be greenish in color and without chlorine), or a suspension of colloidal sulfur (100 g of sulfur per 10 liters of water). Treatment with infusion of rotted manure (preferably cow manure) gives good results. The manure is infused for 3 days in the ratio: 1 part manure to 3 parts water, then diluted with water three times, filtered. Spraying should be done on cloudy days or in the evening. The solution should get on both sides of the sheet. You can use lye from ash: 0.5 buckets of wood ash are boiled in 2 buckets of water for an hour. Add 30-40 g of soap to the cooled filtered solution.

TOPAZ is faster and more effective against powdery mildew

I had the same garbage last summer, I wonder if they will heal on their own or is it necessary to spray this year? It’s probably too late to save the harvest now ((?

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).

Of course, you can treat it, but most likely the affected berries will hardly grow.

1) there is a drug TOPAZ - it is against powdery mildew. It is sprayed 2-3-4 times per season, starting 1) in early spring - only branches 2) when leaves begin to appear 3) BEFORE flowering 4) AFTER the formation of berries. You can skip one of the sprays... But you can spray it now.

2) there is a folk method - very smelly - an infusion of green grass fermented for 1-2 weeks with water (green manure). Prepare this infusion, strain and spray the bushes with it. But you no longer have time for this method.

3) buy varieties of plants and bushes resistant to powdery mildew.

if that's what I'm thinking.

The most reliable remedy is to replace old varieties with resistant ones.

Otherwise, you are doomed to constantly fight powdery mildew.

Harmfulness can be partially reduced by

adding more potassium-phosphorus fertilizers,

mulching the soil under the bushes with manure and rotted straw, etc.

But it is almost impossible to eradicate thoroughly.

Do you need chemically-treated berries?

Shadow, crowded conditions, poor ventilation,

changes in temperature and humidity,

high temperature combined with drought -

constant provocateurs of fungal activation.

It’s difficult to change this year, but for the future, in early spring, when there are still morning frosts, I pour hot water from a watering can on the currant and gooseberry bushes early in the morning and this problem will not exist.

Powdery mildew. We cut the branches down to the roots and sprinkled the remaining part of the bush with ash. It is better to burn the affected branches. Now maybe they have come up with something more perfect.

Brown plaque is SCAB, powdery mildew is white plaque! And it was necessary to spray for scab in the spring. But if you rub the berry, you will erase this coating, GOOD LUCK.

American powdery mildew or spheroteca. M, B.: resistant varieties, 1% solution of colloidal sulfur during the growing season, 0.5: solution of soda ash + 0.4% solution of laundry soap. The first spraying is before flowering, the second - immediately after flowering, the subsequent ones - 5-10 days after the previous one. And all agrotechnical measures aimed at better development of plants.

I sprayed it with a solution of household soap and soda ash - the berries were partially peeled - try - 100 grams of soda per bucket + soap using a grater by eye. soap is added. so that the soda sticks to the leaves and berries

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 berries 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).
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 steep 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 preventative 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!
