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.
Control measures against powdery mildew or spheroid 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 could not be avoided, then Bordeaux mixture will be an effective means of combating 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).
White blooms on gooseberries are usually a sign of powdery mildew. This disease is dangerous for many cultures. If measures to combat powdery mildew are not taken in a timely manner, it can lead to massive death of plants on the site.
A whitish coating can be found on the stems, fruits or leaves of gooseberries. Organs affected by the disease change shape and become twisted. In this case, fruit growth slows down significantly.
Powdery mildew occurs in spring or summer as a result of crop damage by fungal organisms. The disease progresses in cold, rainy summers, as high air humidity promotes the spread of the disease.
Representatives of tall berry varieties are most susceptible to the disease, because such plants are often pruned. Low-growing plants can be susceptible to powdery mildew if they are not properly cared for.
Fighting methods
When the first signs of a disease are detected, you should first of all eliminate all unhealthy plant organs, and then treat the crop with chemicals or natural solutions.
Folk remedies
A white coating has appeared on the gooseberries - what to do?
You can spray the bushes with natural solutions that are absolutely harmless to humans.
There are many recipes for creating such solutions, but the most commonly used are:
- Pour 3 kilograms of tree ash into a bucket of hot water and let the solution sit for 24 hours. Next, you should strain the mixture and spray the gooseberries with it before flowering and immediately after it. It is worth repeating the treatment several more times (frequency: once a week). On average, one bush requires about 3 liters of spraying liquid.
- Fermented grass that can be created using weeds and water. The collected weeds should be chopped and poured with hot water. You need to use about 5 kilograms of weeds (half a bucket). After placing the herbs in a container, you need to fill them with water to the top of the bucket. After this, you need to let the mixture brew for several days. Before processing, the tincture must be strained. The procedure is best done in the afternoon.
- Mullein will help cure crops from powdery mildew. To do this, you need to fill a third of the bucket with mullein and fill it to the top with cold water. Next, you need to let the solution brew for several days (a couple of days). The infusion should be stirred periodically and filtered before processing the bushes.
- Dairy products will also help rid gooseberries of white plaque. To prepare the solution you will need water and whey (homemade or purchased). There should be 10 times more water than whey. The components in such quantities are mixed until a homogeneous solution is obtained. The mixture in its finished form needs to be treated with plants from time to time until they are completely recovered.
Chemicals
Today there are many chemicals that can defeat powdery mildew on gooseberries. However, summer residents prefer the following:
- Copper sulfate. Based on it, you can prepare a solution that will help defeat the disease in the shortest possible time. It is enough to use 0.1 kilograms of vitriol per bucket of water. Gooseberries need to be processed from the beginning of spring until the buds begin to bloom. Not only the bush, but also the ground under it must be processed.
- The drug "Topaz". This chemical is widely used by gardeners. Plants need to be sprayed in stages. The first time is before flowering begins, and the second time is immediately after it.
- The drug "HOM" is an alternative version of Bordeaux mixture. It is worth diluting 40 grams of the substance in a bucket of water. On the basis of "HOM" it is possible to create a complex preparation. To do this, you need to add some substance against pests to the solution. Each component is diluted in a separate container. After this, all solutions are poured into one container.
Secrets of prevention
You can prevent the appearance of powdery mildew on gooseberry bushes. To do this, it is enough to carry out simple activities:
- Timely and properly pruned bushes will help the healthy development of the crop. A plant that develops properly is able to resist various ailments, in particular powdery mildew.
- During active berry growth (spring/summer), you should carefully monitor the condition of the plant. As soon as you find diseased branches on the bushes, remove them immediately. Timely elimination of diseased organs prevents the development of the disease. The spores of the pathogenic fungus overwinter on the shoots of the plant and last year's fallen leaves. Therefore, in the spring it should be removed too.
- With the onset of spring, when the snow has melted and the temperature does not drop below zero, gooseberries can be given a “contrast shower” with hot water (the procedure is carried out until the buds swell). You can add a little soda or manganese to the water.
- You can increase a crop's resistance to disease by fertilizing the plant with phosphorus and potassium fertilizers (but not nitrogen!).
Powdery mildew is a dangerous disease, but it can be overcome. Effective control will be beneficial both to the plant itself and to its harvest.

- Brown spot (anthracnose) is a fungal disease of currants. Appears as small brown dots on the leaves. The spots subsequently merge, the leaves turn brown and fall off. Anthracnose on currants, gooseberries and raspberries - with a 1% solution of Bordeaux mixture or a 1% solution of ferrous sulfate.
- baking soda per liter of water. Try spraying it like this now.
- In spring, rust spores are carried by the wind to leaves, shoots or young gooseberry ovaries. At the sites of infection, bright yellow-orange pads appear, resembling glasses. They are clearly visible on the underside of the leaves or against the background of the green ovary. The affected parts of the plants fall off without infecting healthy leaves. The carrier of the disease is sedge.

As soon as the bushes come out from under the snow, pour hot water (80°C) over them. When the first signs of the disease appear, spray with topaz (2-3 times with an interval of 10-14 days), Vectra (before and after flowering) or strobe (once every 2 years after flowering). To prepare a working solution, 20 g of one of these drugs is diluted in 10 liters of water.
a But in the fall or next early spring, it is imperative to cut off and burn the tops of the affected shoots. Pre-treatment of gooseberries or in the first stages of the disease can be done using a very weak solution of potassium permanganate, up to 1.5 g per bucket of water.

places increased demands on potassium nutrition, then on soils with high fertility you can get by by adding only ash (1 cup each) or 20-30 g of potassium sulfate (or potassium magnesium, depending on age) under the bush. On rather poor soils, such as sandy, sandy loam or ordinary, but poorly cultivated soils, it is advisable to add compost or humus. When planting in such soil in the summer, it is advisable to carry out 2 feedings. The first in June, and the second at the beginning of berry set. As a fertilizer, you can take an infusion of grass or manure, to which it is good to add Baikal EM1 in a ratio of 1:100 to reduce the odor and improve the chemical composition. If you have no time to prepare an infusion or have nothing to use, then you can use an organic fertilizer such as Gumistar, which can also be used for foliar feeding (by leaves). After heavy rains, especially on light soils, magnesium deficiency may occur, manifested in the lightening of the leaf between the veins. In this case, you should feed with a solution of magnesium sulfate or Aquadon-micro Universal fertilizer (in addition to microelements, it also contains magnesium). It is worth paying attention that the dose of compost depends on the method of application. That is, if organic matter is applied as fertilizer and embedded in the grooves, then 4-6 kg is enough to provide nutrition, but if you simply scatter it as mulch, then up to 2.5-5 buckets, that is, with a sufficient amount of organic matter, mulching alone is enough. If compost is in short supply, you can do this: first add ½-2/3 of a bucket of it into the grooves, and then mulch with sawdust (preferably soaked in a solution of urea or ammonium nitrate) or dried grass, for example, weeded weeds. However, this approach is also applicable to other crops, for example, currants, honeysuckle, gooseberries, and some fruit trees. The only difference is the dose. For high fruit set, it is advisable to provide it with cross-pollination: for this you should plant a blackcurrant and gooseberry bush.

When growing gooseberries on your property, you may encounter an unpleasant disease - powdery mildew. At the initial stage of infection, a white coating appears on the plants. Advanced stage – brown spots on berries and leaves, growth arrest, leaf deformation. If you do not treat the bush, the shoots may dry out and the berries may fall off.
Causes of white plaque on gooseberries
Powdery mildew is a fungal disease that progresses from spring to summer, during periods of high air humidity. Due to rainy weather, fungal spores multiply quickly in a humid environment. White plaque affects the leaves, berries, and stems of gooseberries. In dry, hot conditions, the spread of fungus is reduced. Tall plants after pruning and perennial low-growing, neglected bushes are susceptible to this disease. The spores infect gooseberries, getting into the cut wounds.
Be careful, powdery mildew can infect neighboring garden plants.
Signs of powdery mildew:
- white bloom on gooseberries, on the underside of the leaves;
- deformation of the affected parts, curling of leaves;
- slowdown in fruit growth and leaf mass development;
- white bloom turns into fluffy flakes on the berries, the upper and lower parts of the gooseberry leaves;
- the appearance of brown spots with black dots (fungal spores);
- drying of shoots;
- falling, cracking of berries.
Folk remedies
To successfully combat powdery mildew, when gooseberries are covered with a white coating or show other signs of the disease, the following available components are used:
Ingredients | Cooking method | Directions for use |
Wood ash | Pour sifted ash (1 kg) with warm water (10 l), leave for 6-7 days. | Ash infusion is used to spray bushes 4 times, with an interval of 2 days. |
Onion and garlic peels | Pour boiling water (10 l) over dry husks (200 g) and leave for 2 days. | Spraying with infusion before the flowers appear, after flowering and in the fall before the leaves fall off. |
Laundry soap, soda and water | Add grated laundry soap (50 g) and two tablespoons of baking soda to a bucket of water (10 l). Stir until completely dissolved. | The gooseberries are immediately sprayed from all sides with the prepared solution. |
Cow dung | Concentrated mullein (1 l) is mixed with water (3 l). Leave for 3 days in a dark place in a hermetically sealed container. Before processing, strain the resulting concentrate and dilute it with water in the ratio: one to three. | Spray during budding, after flowering, before leaves fall. |
Whey, fresh milk or kefir | Any dairy products (1 l) are mixed with water (9 l). Immediately applied for processing. | Spraying gooseberry bushes from all sides 3 times with an interval of 3 days. |
Potassium permanganate solution, tansy infusion, wormwood | Potassium permanganate (1.5 g) is diluted with water (10 l). Instead of water, cold decoctions of medicinal herbs are used: tansy, wormwood (30 g of raw material per 10 liters of water). | Treatment is carried out throughout the season, after rains. |
Chemicals
If the leaves, stems and berries of the gooseberries are covered with a white coating, and folk remedies for combating the disease do not bring the desired results, you should resort to specialized means. During the spring-summer period, there are three main phases of treating gooseberries against powdery mildew:
- before flowers appear;
- after flowering;
- a month before harvest.
Gooseberry diseases American powdery mildew, spheroteca Among the chemicals, the most effective are:
Name | Cooking method | Directions for use |
Copper sulfate. | Dissolve the powder (100 g) in a 10 liter bucket of water. | The cultivation of the bush and the ground under it is carried out from the beginning of spring until the buds open. |
Superphosphate, potassium chloride, urea, potassium permanganate. | In a bucket of water (10 l), stir superphosphate (20 g), potassium chloride (50 g), urea (30 g), potassium permanganate 5 g. | Treatment is carried out once after flowering. |
Fitosporin. | Stir the product (100-150 g) in a bucket of water (10 l). | The gooseberries and the soil under them are processed three times per season. |
For 10 liters of water, use 2 ml of product. Apply immediately. | Treatment is carried out throughout the growing season with an interval of 14 days. Liquid consumption: 10 liters per 100 square meters. |
Prevention
In autumn, parts of the plant damaged by white or brown plaque are removed. All fallen leaves and weeds must be collected and destroyed. The soil next to the plants is regularly loosened and dug up in spring and autumn. Such procedures contain the fungus and prevent it from spreading further. For prevention it is used:
- Fertilizing with phosphorus-potassium fertilizers strengthens gooseberries, increasing resistance to diseases and adverse weather conditions.
- Timely rejuvenating pruning and cutting off old, diseased branches throughout the growing season.
- In the spring, after the snow melts, before the buds open and the air temperature is above zero, a “shock shower” is done with hot water. To disinfect and enhance the effect, soda or manganese is added to this water.
Old gooseberry varieties are less resistant to various diseases. Even an experienced summer resident who carefully monitors his plantings may be affected by a white coating on his bushes.
Often you don’t want to remove the variety you like, but what to do with diseases and how to treat them?
Where does the white coating on gooseberries come from?
In mid-summer, a whitish coating and brown spots can be seen on the leaves, stems and fruits of gooseberries. Damaged parts of the plant curl, become deformed, and fruit growth slows down. This indicates that the plants have been attacked by powdery mildew.
Powdery mildew is a fungal disease that progresses on gooseberries throughout the spring and summer. Fungi infect the upper part of the leaf, the berries crack and fall off, and develop poorly.
In cold and rainy summers, the development of the disease accelerates. High air humidity favors the spread of fungus. In dry and hot weather, the disease progresses less.
Most often, tall varieties of gooseberries, which are often pruned, are affected by the disease. Low-growing, weakened species that are not properly cared for are also susceptible to powdery mildew.
As a preventive measure and to enhance immunity plants need to apply phosphorus-potassium fertilizers, loosen the soil under the bushes. A progressive disease, the presence of a strong white coating on the berries can destroy the entire crop. When the first signs of the disease are detected, control measures must be taken immediately.
Powdery mildew is transmitted from one plant to another. Fungal spores multiply quickly and can infect neighboring currant plantings.
How to treat white plaque on gooseberries
You can avoid the appearance of powdery mildew by growing varieties that are resistant to its appearance. But if the gooseberries are still covered with plaque, then what should you do in that case?
1. It is necessary to begin the fight against the wintering form of the infection.
2. Carry out preventive spraying three times a season.
3. Increase plant immunity.
Overwintering infections need to be fought regularly. All damaged shoots and berries must be removed from the plant and burned. In the fall, carry out preventive pruning to healthy tissue. It is imperative to remove all fallen leaves and weeds from under the bushes. The soil under plantings needs digging and constant loosening. Such methods inhibit the development of the disease. In late autumn and early spring, when the buds have not yet blossomed, you need to treat the bushes with copper sulfate. People often advise scalding the bush with boiling water.
If gooseberries become covered with plaque every year, then spraying should be done regularly.
The first spraying is carried out before flowering with systemic fungicides.
The second time the treatment is done immediately after flowering, with the same preparations.
Follow-up treatment should be no later than three weeks before harvest.
Traditional methods of processing white plaque on gooseberries
Gooseberry plantings that are not yet severely affected by the disease can be saved without the use of chemicals. Folk remedies for the fight are quite effective in the initial stages of the disease.
It is important to remember that treatments with infusions must be carried out several times, and the bush must be sprayed again after rain.
When the gooseberries are covered with a white coating, spray with the following solutions:
Ash infusion;
Mullein;
Soap and soda infusion;
Potassium permanganate;
Kefir and sour milk;
Onion peel;
Tansy infusion;
Horsetail.
Preparing the ash solution
Treating shrubs with ash infusion gives good results. You need to prepare such a solution from 1 kg of wood ash and 10 liters of warm water. You need to infuse the ash for a week, shake before processing. Spraying should be done four times with an interval of two days.
Mullein as a remedy for powdery mildew on gooseberries
Many summer residents successfully treat powdery mildew with mullein infusion. To do this, 1 part mullein is diluted in 3 parts water. The resulting mixture should be infused in a warm place for three days. The finished infusion is filtered and the gooseberries are processed.
Soda is the first assistant against white plaque in berry crops
Soda is widely used in gardening. Its ability to fight lime fungi has been around for a long time. To prepare the solution you will need 50 grams of laundry soap, which is pre-grated, 2 tbsp. l. soda and 10 liters of water. The prepared solution is used immediately and is not stored. Spraying with soda is best done before and after gooseberries bloom.
How to make a manganese solution
Manganese can be used to spray gooseberries to remove white plaque on the berries. The solution is prepared from 10 liters of water, to which 1.5 grams of the substance is added. Preventative treatment should be carried out once a week and after rain.
How to prepare a solution from sour milk
As you know, fungi quickly die in an acidic environment, so sour milk or kefir is used to spray gooseberries during the growing season. Serum is used for the same purpose. For the working solution, take 1 liter of sour milk and mix it with 9 liters of water. The prepared solution is shaken well and sprayed three times, with an interval of three days.
How to use onion peels to remove white plaque on gooseberries
To combat powdery mildew and boost immunity, plants use an infusion of onion peels. During the winter, you can collect and store onion peels, and when spring comes, use them to spray plants.
An infusion is prepared from 200 grams of dry husk and 10 liters of boiling water. You need to insist for two days. It is useful to spray gooseberries with this infusion before flowering, during fruit formation, and after harvesting.
Tansy decoction
Medicinal plants help fight many diseases of berry crops. Tansy infusion is prepared from 30 grams of dried flower and 10 liters of water. Infuse the mixture for 24 hours, then boil it for about two hours and process the gooseberries. The ground around the bush is treated with a hot decoction in early spring and autumn. The treatment should be carried out after harvesting the foliage.
Horsetail infusion
A working solution for spraying is prepared from 1 kg of fresh horsetail. To do this, the plants are crushed and boiled in 10 liters of water for about two hours. The prepared and cooled decoction must be filtered, diluted with water in a ratio of 1:5 and the plant treated.
A decoction of tansy can be used to treat gooseberry bushes throughout the summer season. The interval between treatments should be at least a week.
How to spray gooseberries
Spring and autumn digging of the soil, loosening and other methods are less effective than spraying in the fight against white plaque on gooseberries. Shrubs need to be processed correctly.
The prepared solution of drugs must be thoroughly sprayed with the smallest nozzle. The leaves, shoots and soil under the bush are treated. First, treat the upper part of the leaves, then the lower part. When spraying, you should try to get on all the leaves and shoots from all sides of the bush. The ground around should be moistened with the solution until moist.
All work with drugs should be carried out in calm weather. All plants that are located near the affected area can and should be treated.
