Gooseberry powdery mildew fight after flowering. Effective measures to combat powdery mildew on gooseberries

The sweet and sour gooseberry is loved by many gardeners. Yes, and how to do without a single bush on your suburban area knowing about great benefit gooseberry? After all, it is the richest source of vitamin C.

That's just growing in your garden this berry, not everyone manages to get large and beautiful fruits of the crop due to ignorance of how to protect the bushes from various pests and diseases. One of the most difficult problems for beginner gardeners is the appearance of powdery mildew on gooseberries. This disease is the worst enemy for the plant, which destroys not only the fruits, but also eventually kills the viability of the entire bush, even affecting the roots.

powdery mildew

Powdery mildew on gooseberries is fungal disease spread by microscopic spores. Gooseberry bushes can become infected through insects that carry spores, or mycelium with spores can get on the plant bush with the help of wind masses.

Read also the article:! Powdery mildew develops not only on gooseberry bushes, but is also worst enemy raspberries, currants, . Finding the affected areas with this disease is not at all difficult. Mushrooms with spores form a white coating on gooseberry foliage, similar to scattered dry flour.
Powdery mildew affects not only the leaves of the bush, but also young gooseberry shoots. If measures are not taken in time, then powdery mildew eventually affects gooseberry fruits.

The disease begins its development at the end of May, when the gooseberry forms new shoots and throws out the color for the further formation of the fruit ovary. favorable conditions warm weather and a humid atmosphere provide spore breeding.

The development of the disease begins with the lower branches of the bush, it is on them that last year's infecting spores can survive. Many summer residents, not recognizing powdery mildew at the very beginning, are surprised at such a picture.
This is what powdery mildew looks like after a few weeks, the light coating becomes rough and changes its color to brown. Such fruits are unsuitable for consumption, since the peel is very difficult to peel off the berries, especially when they ripen.

All affected leaves curl over time, stop growing, and the shoots change their arcuate shape and dry out. Most of the ovary falls, resulting in crop loss. If the plant is not helped, then it simply dies.

How to deal with powdery mildew?

Even such complex diseases fruit bushes, like powdery mildew, can be prevented and defeated. Fighting powdery mildew involves three approaches.

• Agrotechnical - applicable for minor damage to the bushes, when isolated cases of damage are found.

This method consists in planting gooseberry varieties resistant to powdery mildew and timely pruning infected branches in autumn or in early spring.

To resistant varieties include Kolobok, Harlequin, Ural grapes, Grushenka, Kuibyshevsky, Masha, Senator, African, Jubilee, Finnish, Houghton.

Cut off infected material is burned or buried in the soil in places remote from the gooseberry plantation.

With the onset of the first spring heat, it is necessary to remove last year's foliage from under the gooseberry bushes, which can also serve as an excellent breeding ground for spores.

Damaged leaves and branches should be removed immediately. Before the buds swell on the branches of the gooseberry bushes, they are treated with a potassium permanganate solution heated to 90 ° C, namely hot shower disinfects all branches and soil under the bush itself (two tablespoons of potassium permanganate are diluted in ten liters of water).

It is worth feeding gooseberry bushes only with potash and phosphate fertilizers, which are responsible for the formation of full-fledged strong shoots that can resist powdery mildew, while nitrogen fertilizers, on the contrary, inhibit the development of young shoots, due to which they are more susceptible to damage by this disease.

• Chemical - applicable when large gooseberry plantations are infected and consists in spraying the bushes with potent drugs.

To do this, use copper sulfate (one hundred grams per ten liters of water), drugs "Topaz", "HOM", "Thiovit Jet", "Vectra", "Cumulus".

• Agrochemical - a combination in practice of the above methods of combating powdery mildew.

In the question of how to deal with powdery mildew on gooseberries, folk recipes are also valuable, the effectiveness of which has been proven by the practice of many gardeners.

Folk methods of treating gooseberries for powdery mildew include the following measures of influence:

• preparation of a solution for spraying gooseberry bushes from soda and grated on a coarse grater laundry soap(for ten liters of water, fifty grams of soda and soap);
• preparation of a solution with ash (for ten liters of water, three kilograms of ash);
• preparation of a solution with urine (for five liters of water one glass of urine).

Spraying of bushes is carried out in the same way as with chemicals, before flowering and after it, if necessary, the action is repeated several more times.

Gooseberries without powdery mildew - video

Sferoteka, or in a simple way - powdery mildew, appears in all its glory on gooseberry bushes in June. A white moss-like coating covers berries, leaves, shoots, mostly young ones. The disease can not only deprive the summer resident of the harvest, but also completely destroy the bushes. How to treat gooseberries from powdery mildew in the spring, what means give a greater effect - these questions concern gardeners, experienced and beginners.

What kind of "chemistry" to spray gooseberries?

The fungus that winters well in the root zone - the causative agent of powdery mildew - awakens in the spring and rapidly sheds spores, infecting neighboring plants and soil. Although the disease enters its full "color" in early summer, all preventive actions carried out in the spring, as soon as the snow melts.

If powdery mildew was noticed on the site last season, in the first days of spring, measures must be taken to curb the spread of the sphere library, and preventive treatment of gooseberries is carried out. Experienced gardeners may notice signs of damage even before bud break.

The following drugs are popular in the fight against fungus among summer residents.

• "Nitrofen". Spraying is carried out strictly before the opening of the kidneys. For processing, 200 g of the drug is diluted in 10 liters of water.
• "Topaz" - a solution for spraying is prepared by diluting the contents of 1 ampoule of the product with 10 liters of water. Plants are treated 2-3 times before flowering with an interval of 2 weeks. The drug is moderately toxic to humans and pets. It is not used near water bodies.
• "Tilt KE" - suitable for the prevention and treatment of already diseased bushes. It has the ability to penetrate into the cells of the surface tissues of plants, which increases its duration. The spray emulsion is prepared at the rate of 0.4 ml per liter of water. The result is obvious within a couple of hours after application. The drug is not used if there is an apiary or fish ponds nearby.

Also for treatment and prevention use "Emistar Extra", "Vitaros", "Skor".

It is possible to process gooseberries before the buds bloom, with proven means:

• copper sulfate - 80 g / 10 l of water;
• iron sulphate - 30 g / 10 l of water;
• ammonium nitrate - 50 g / 10 l;
• potassium permanganate - 1.5 g / 10 l of water.

Simultaneously with the treatment of the shrub, the funds are sprayed on the ground.

At the stage of bud formation, it is effective to use copper oxychloride, dissolving 30 g of the drug in 10 liters of water.

For the prevention or treatment of powdery mildew on gooseberry bushes, colloidal sulfur is not used, since it causes loss of leaves in the plant.

Chemical preparations of the same name are not used for more than 2 years in a row, since the mycelium can adapt to adverse conditions.

Biofungicides

Spraying gooseberry bushes with biofungicides is carried out when the daytime temperature is above 15 ° C. It is possible to apply them at all stages of the growing season. Effectively work against powdery mildew "Planriz", "Fitosporin-M", "Pseudobacterin-2", "Trichodermin".

An excess of nitrogen in top dressing increases the sensitivity of gooseberries to the causative agent of the disease.

Folk remedies to combat the sphere library

The use of folk remedies in the prevention of the disease is no less effective than the use of chemical or biological drugs. But the old recipes that came out of the people are completely safe for people, birds, pollinating insects and other inhabitants of the garden plot.

A feature of the use of folk remedies on gooseberries is that the bushes are not sprayed, but each shoot is abundantly moistened.

• Watering with boiling water

The procedure is carried out as soon as the snow melts. Previously, all debris is removed from under the bushes. Exposure to temperatures above 60 ° C is detrimental to the spores of the sphere library, very often such a simple procedure is enough to completely get rid of the causative agent of the disease.

• wood ash

Ash - good remedy against a number of gooseberry pests (moth, aphids, sawfly, snails, slugs). At the same time, it serves as a supplier of calcium, potassium, phosphorus, and reduces the acidity of the soil.

For spring processing, they take dry ash, sift it. Dusting bushes is carried out at the rate of 15-20 g for each bush. At the same time, the ash is poured into the soil under the root (300 g / m 2) when digging, spilled with water, and dry earth is poured on top.

During the spring, four or five gooseberry treatments with ash are carried out, but already in liquid form. An infusion prepared at the rate of 300 g of ash per liter of water is kept for 5 days, then the shrub is abundantly sprayed.

• soda ash

Before flowering and immediately after its completion, gooseberry bushes are treated with a solution of soda. First, 50 g of the product is diluted in boiling water, then water is added to a volume of 10 liters, 1 tbsp. l. liquid detergent.

• soda with aspirin

Prepare a solution for spraying from 1 tbsp. l. soda, 1 aspirin tablet, 1 tsp. liquid soap, 1 tbsp. l. any vegetable oil, 4.5 l warm water. Gooseberry treatment begins from the moment the buds open, repeat every 2 weeks.

Normal for home first aid kit Zelenka also helps to get rid of the fungus. 2 drops of antiseptic are added to a bucket of water, gooseberries are sprayed.

• Mullein

The processing solution is prepared in the following way: 1 part of rotted manure is diluted with 3 parts of water, insisted for 3 days, filtered, 3 parts of water are added to 1 part of the infusion. The product is suitable for treating plants before and immediately after flowering. Similarly, use rotted hay or straw.

• Whey, kefir or sour milk

A liter of dairy product is diluted with 9 liters of water. Spraying is carried out three times during the week on young leaves. To increase the effectiveness of the solution, add 10-15 drops of iodine to it.

• onion peel

200 g of raw materials are boiled for 10 minutes in 10 liters of water, let it brew for 2 days, filter, squeeze the husk into an infusion. Processing is carried out before flowering and after it ends.

• Tansy

Dry leaves and flowers (300 g) are poured cold water(10 l), insist 2 days. Slowly simmer for 3 hours, strain. The resulting solution is sprayed on the ground under the bushes after spring digging.

• horsetail

100 g of dry grass is soaked in 10 liters of water, after a day of infusion, boil over low heat for an hour. The cooled broth is diluted with water 1:5. Horsetail is used to treat gooseberries with early spring until the end of the fall.

Spraying gooseberries with fertilizers immediately after the end of flowering performs two functions at the same time: it feeds the bush along the leaf and prevents infection with powdery mildew. The solution is prepared from 20 g of superphosphate, 50 g of potassium chloride, 30 g of urea, 5 g of potassium permanganate, 10 l of water.

How to properly treat gooseberries from powdery mildew?

The first treatment of gooseberry bushes is carried out strictly before the opening of the kidneys. To do this, select a chemical fungicide or folk remedy, including watering hot water. The term of the second treatment is the beginning of flowering, it is optimal to use biological products or products prepared according to folk recipes. The third spraying - after flowering is completed. Apply biofungicides or folk methods.

Shrubs are processed in the following order:

1. For the procedure, choose a dry cloudy windless day or the afternoon hours of a sunny day.
2. Carefully spray the crown, making sure that the product is sprayed on both sides of each leaflet - upper and lower.
3. Similarly, the side parts and the base of the bush are treated.
4. Watered medicinal solution soil under and around gooseberries.

It is advisable to simultaneously treat plants and soil in nearby beds.

Agricultural practices

It is difficult to achieve a stable positive result with the treatment of shrubs alone. It is also important to observe the simplest agrotechnical rules:

• thinning shrubs, timely cutting of old branches that give few berries;
• maintaining cleanliness under the bushes, regular removal of debris;
• rejection nitrogen fertilizers.

Some gardeners successfully use the dry remains of garden and garden plants to control the powdery mildew pathogen. trunk circle cover with tops, watered with a solution of the EM preparation. Beneficial microorganisms feed on spores and mycelium of the sferoteka with pleasure.

A positive result in curbing the spread of spores of the sphere library is given by sowing under the bushes of doctor plants - garlic, marigolds (tagetes), dill, parsley, mint. The first two also protect plants from pests, flowering marigolds and spices attract beneficial insects.

Gooseberry protection from powdery mildew is a constant process, the lightest spores are regularly carried by the wind. spring processing bushes protects berry bushes from pathogens introduced in autumn. In order to fully protect the garden from the spherical library, you need to constantly monitor the condition of the bushes, prevent them from shading, thickening, spray them with the optimally selected composition in due time, and cut out shoots with signs of damage with a firm hand. Compliance with the whole range of measures will preserve the harvest of gooseberries and the health of all plants on the site.

The gray-white coating that appeared on gooseberry berries is a sign of infection of the plant with a dangerous fungal viral infection- powdery mildew. An uninvited "guest" came to us from America. The disease spreads rapidly throughout the culture. White color over time it becomes gray and even acquires a brown tint. Adaptation to harsh winters contributes to the survivability of viruses. They endure our frosts on damaged bushes, so that with the onset of spring they multiply again with spores that already fall on nearby growing plants. When the first signs of powdery mildew are found, you need to know what to do with fruit crops, what control measures to apply.

Dangerous fungus

The fact that the gooseberry is useful, a storehouse of vitamin "C" is known not only to man. Powdery mildew also "knows" about it. Microscopic spores of the fungus are brought by the wind, along with birds and insects. Raspberries, yoshta, currants settle on bushes. In the last decade of May, according to the characteristic white bloom – initial stage infections - on the green shoots of the pest and are found. These are mushrooms. Given the rapid reproduction, the fight against powdery mildew on gooseberries begins immediately after the first symptoms appear, until the fruits have formed.

Spring warm days with rains create comfortable conditions to reproduce spores. 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. Leaves, and then fruits covered with a white coating, after a while have an unattractive appearance of rust with a hard crust that is difficult to clean. Sheet plates deform, twist, stop developing. Young growth on the bushes dries out.

"Weaknesses" of powdery mildew

Like any pest, powdery mildew is "afraid" of chemistry. All preparations in liquid form are applied by spraying three times during the development period: in the spring, before the onset of active vegetation, when the first flowers appear, and another one and a half weeks after the start of flowering. Moreover, for preventive purposes, it is also necessary to treat neighboring plants with chemicals.

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

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, to the soil in the root zone. Special attention given to the wrong side (shadow) side: under the branches, with reverse side leaves. The plant is conditionally divided into zones and irrigated in turn: the “top”, “sides” and the bottom of the bush with the capture of the soil around it.

• Among the available and inexpensive means -. 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.
• Good effect and from the solution (0.2 kg of the drug and 10 liters of water room temperature). Apply before bud break.
• You can get rid of powdery mildew on gooseberries with the appearance of buds if their branches are sprinkled with a composition. It is sold in specialized stores or prepared independently. Bordeaux mixture from powdery mildew on gooseberries is used 3%. For cooking, you need to take: copper sulfate (copper sulfate) - 0.3 kg, lime - 0.4 kg, water - 10 liters. First, vitriol is dissolved in 1 liter of water. Then, after complete dissolution of the salt, another 5 liters of water are added. Received saline solution poured gradually into a solution of lime. Well mixed, filtered. You should get 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). In a weak solution prepared from 1.5 g of the drug per 10 liters of water, it is applied to the gooseberry twice: before flowering and again after 10 days. 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. To hot compositions, the branches of the plant, as well as the soil under the bushes, are irrigated before the formation of buds for the purpose of prevention.
• In the distribution network you can buy drugs for chemical basis that kill the fungus (fungicides):, Skor, HOM, Abiga-Peak 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 the plant and during the fruiting period.

Physical and cultural measures

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

• When the snow melts, all the foliage wintering under the bushes is burned along with spores.
• Gooseberries are regularly inspected. Cut off at the first appearance of infected branches. This should be done on the eve of winter and with the onset of spring. All trimming is burned, or it needs to be dug outside the boundaries of the garden.
• In a critical situation, when none of the processing methods helps, you should act radically: uproot and burn the infected bush.
• Most effective method get rid of the pest - plant varieties resistant to powdery mildew fruit crops: "Finnish", "Harlequin", "Houton", "Gingerbread Man", etc.

From public stocks

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

Common household formulations, nutritional supplements or medications in our home first aid kits will help get rid of the pest without resorting to drastic measures.

If the gooseberry is a longtime inhabitant of the dacha, growing there since the time of your grandmother, who got hold of cuttings from her great-grandmother, then most likely you have encountered the problem of powdery mildew more than once. It manifests itself as a whitish coating covering the leaves and stems, and unpleasant brown spots on berries. The advantages of old varieties include a wonderful taste and the absence of various modifications, but there is also a huge disadvantage - low disease resistance.

Cut out delicious variety I don’t want to, but the desire to part with the pest is great. And preferably without the use of toxic pesticides. Take advantage of proven folk remedies. They are highly effective both in the fight against powdery mildew and in measures to prevent it.

What is powdery mildew

In scientific circles, this gooseberry ailment is called a sphere library. It affects almost the entire plant, from shoots to fruits. At first, a whitish coating forms, which later becomes brown, similar to felt. Diseased stems are bent, the leaves are twisted, and the berries are smaller and weakly poured.

Fungal microorganisms with the same name provoke the disease, and they throw out spores both in spring and in spring. summer period. Therefore, it is optimal to carry out the treatment three times: before the formation of flowers, after that and before dropping the leaves. It is better not to spray the shoots, but to wet each branch entirely. And do not forget that spores love to winter in the litter, which means that it is necessary to shed the soil near the bush with the same medicinal composition. Wellness procedures are best done in the evening.

• Ammonium nitrate. 50 g of the substance must be dissolved in 10 liters of water. The gooseberry bush is processed after it has faded.
• Aspirin + soda. To prepare the composition, use a tablespoon of sodium carbonate and sunflower oil, a tablet of acetylsalicylic acid and a teaspoon of any dishware. All ingredients are mixed in 4.5 liters of water. The plant is systematically treated once every two weeks throughout the season.
• Water. They take boiling water and pour it over a bush from a watering can. The procedure is carried out in early spring before the snow melts.
• Gaupsin or trichodermin. For 10 liters of water, 150 ml of one of the biological products is used and the shoots are sprayed every two weeks throughout the entire growing season.
• Ash. Several options are possible here.
• First. An infusion of ash and water (1:10) is kept for a week, stirring occasionally. After that, the composition is poured into clean dishes trying not to capture the sediment at the bottom.
• Second. Ash and water (0.3: 10) are boiled for half an hour, cooled and, after waiting for the ash particles to settle, are poured into another container.
• The third. Take ash and boiling water (3:10), mix and leave for about a day. After filter. Processing ash composition carried out in the last decade of May or the first - June 3 times, making a daily break. The sediment is slightly diluted with water and the soil is shed under the gooseberries.
• Soda ash. In half a glass of hot water, it is necessary to dissolve 50 g of the substance, pour the solution into 10 liters of water, adding about 10 g of liquid soap. The berry is processed before and after the formation of flowers.
• Kefir or curdled milk. In 9 liters of water, stir 1 liter of fermented milk product. Spray the plants three times with a three-day interval.
• Mullein. It must be diluted with water (1:3) and insisted for three days. Then water is added again in the same proportion and filtered. Medical procedures are done before the bush blooms, after that and before the leaves fall.
• Onion peel. Golden scales (200 g) are placed in 10 liters of boiling water and left for two days. Spraying is done before and after forcing flowers and immediately before leaf fall.
• Whey from milk. A liter of the product is diluted with nine liters of water. Gooseberry branches are processed three times with a three-day interval.
• Tansy. They take 10 liters of water, tansy - 30 g of dry inflorescences and insist for a day. After boiling for 1.5-2 hours, filter. Tansy broth is shed around the bushes at the beginning and end of the growing season.
• Overripe hay or forest litter. Hay is placed in a bucket by one third, filled to the top with water and kept for 3 days. Then the composition must be diluted with water 1: 3 and filtered. Bushes are treated before and after flowering and before foliage falls.
• Soda. Two tablespoons of the substance and 50 g of dark laundry soap, grated in advance, are mixed with ten liters of water. Spray the bush before and after forcing flowers.
• Fertilizers. Superphosphate - 20 g, urea - 30 g, calcium chloride - 50 g, potassium permanganate - 5 g are added to ten liters of water. The treatment is carried out once after flowering.
• Phytosporin. Combine water and a biological product in a ratio of 10:0.1-0.15. Branches and soil are processed before the formation of flowers and after picking berries.
• Horsetail. A kilogram of fresh grass and 10 liters of water are boiled for 2 hours, cooled, filtered and diluted with water 1:5. The entire growing season, the bushes are treated once a week.

Remember that powdery mildew thrives in wet, dense plantings and in soils poor in organic matter.

That is why it is necessary to systematically remove old shoots so that the bush is well ventilated with air, and also enrich the soil with organic compounds. Instead of traditionally digging the ground under the berry bush, weeding out the weeds and removing the litter (a fungus can hide there!), It would be better to put tops under the gooseberry - potato and tomato are very good for this - and water it with solutions of EM preparations. Then the beneficial microflora will take matters into their own hands and “gobble up” the organic remains, having a bite of a fungal nursery.

Processing gooseberries from powdery mildew (video)

Powdery mildew control methods

First of all, you need by autumn remove all diseased branches and burn them, also leaves under the bush, as they accumulate a huge amount of acrospores, which in the spring they will disperse and infect new branches and other shrubs.

Early spring, even before bud break, bushes sprinkled with hot water and sprayed solution Bordeaux liquid, which is bred according to the instructions. If, during flowering and tying berries, areas with white bloom still appear, treat them fungicides, but no later than 30 days before harvest.

You can save gooseberries from powdery mildew with the following folk methods:

. calcined soda and laundry soap. To do this, dilute 100 g of soap and 50 g of soda in 10 liters of water, mix and spray diseased shrubs.

. Laundry soap and blue vitriol. The working solution is prepared from 100 g of laundry soap and 5-10 g of copper sulfate. The soap is cut into shavings and dissolved in 1 liter of water, then vitriol is poured into 9 liters of water, mixed and poured soap solution. If done correctly, you will get a bluish liquid without flakes.

Process garden shrubs several times at intervals of 4-5 days and you can get rid of American powdery mildew.

Powdery mildew PREVENTION:

1. Pruning gooseberry bushes in autumn or early spring contributes to good development bush and helps to resist various diseases, incl. and powdery mildew. During pruning, be sure to remove the branches affected by the disease, and then it is better to burn them or take them away from the site and bury them deeper.

2. During the entire growing season (i.e. spring and summer), the shoots and berries found infected with the disease should be removed if possible. It is believed that the spores of the disease hibernate on the affected shoots, and sometimes on fallen leaves. Therefore, in early spring, last year's foliage from under the bushes should be removed.

3. In early spring, when the snow has just melted around the bushes, and the threat of severe frosts has passed, but strictly BEFORE the buds swell, it is good to pour hot (+90) water over the gooseberry bushes. In such water, potassium permanganate can be dissolved up to color pink or soda (1-2 tablespoons per 10 liters of water). Such a "hot shower" is good as a prophylaxis against many fungal diseases, and on blackcurrant, they say, it also helps with spider mites.

4. As fertilizers, use only potash (which includes, for example, ash) and phosphorus. They contribute to the resistance of gooseberries to powdery mildew. But it is better to refrain from nitrogen fertilizers. Nitrogen can cause the shoots to fail to mature and become more susceptible to powdery mildew as a result.

These methods of prevention are useful to use in combination.

RECIPES FOR TREATMENT of powdery mildew with chemistry and folk remedies:

1. In early spring, BEFORE the gooseberry buds swell, spray the bushes and the litter around them (last year's grass, leaves) with a 1% solution of copper sulfate (100 g of copper sulfate per 10 liters of water).

2. Magazines and literature recommend using chemical drug"Topaz" (according to the instructions). If necessary, spray with this solution twice - BEFORE flowering and immediately AFTER flowering. You can get by with one spraying - immediately AFTER flowering. I have tried this drug in practice and can confirm its effectiveness.

3. An excellent preparation for the fight against powdery mildew is "HOM". This is a kind of substitute for Bordeaux mixture. The bushes are sprayed with a solution of HOM (0.4%, i.e. 40 g of HOM per 10 liters of water) BEFORE the gooseberries bloom. Despite the fact that "HOM" is a copper-containing drug, it can be used in combination with drugs against pests. That is, we take 40 grams of HOM and dilute it in a small amount of water. Then we take ampoules of "Fufanon" or "Decis" (calculation according to the instructions attached to the preparations) and also dilute in a small amount of water. Then these two solutions are mixed together and brought to 10 liters of water. Spray BEFORE flowering.

4. 150 g of laundry soap + 20 g of copper sulfate per 10 liters of water.
Laundry soap is rubbed on a grater with large holes. blue vitriol first dissolved separately in hot water, and then pour in a thin stream, stirring constantly, into a soapy solution at room temperature. The resulting soap-copper emulsion should be bluish in color, homogeneous in consistency, without flaking. Spray IMMEDIATELY AFTER FLOWERING, or at worst case immediately after setting the berries.

5. Here are a number of preparations recommended in various literary sources (I, however, have not been tested): Vectra, Skor, Cumulus, Abiga-Peak, colloidal sulfur.
"Thiovit Jet" (20-30 g per 10 liters of water) is characterized, like other sulfur preparations, by a protective and eradicating infection effect on early stages powdery mildew development. It is also used on currants.

6. 50 g of soda (2 tablespoons) + 50 g of laundry soap per 10 liters of water. Soap is rubbed on a grater with large holes. All this is thoroughly soluble in water. I don’t spray the bushes with this solution, but I water it directly from the watering can through the strainer nozzle, and also water the ground around the bushes. Good prevention. This procedure should be done BEFORE flowering, as soon as the leaves begin to bloom, and IMMEDIATELY AFTER FLOWERING. If necessary, you can repeat the procedure 2 more times with an interval of 7-10 days.

7. Daily infusion of ash - 3 kg of ash per 10 liters of water. The ash is poured with boiling water and left for a day, then strain the resulting infusion and spray the bushes with it before and after flowering. This procedure is usually repeated 2-3 times with an interval of 7-10 days. One bush consumes 2.5-3 liters of liquid. I don’t really like this method, because I don’t like to mess around with ash in this way. And besides, for me, ash is primarily important as a fertilizer for cabbage, strawberries, onions and other crops. Therefore, for the treatment of gooseberry powdery mildew, I do not use it. Note - one liter jar holds 500 grams of ash.

8. And one more way to deal with powdery mildew. Take 200 g (1 glass) of urine and dilute in 5 liters of water. The resulting solution is immediately sprayed with bushes. This spraying is carried out immediately AFTER the gooseberry blossoms. The procedure is repeated 3-4 times per season with an interval of 7-10 days. This recipe was shared by one of the readers of the magazine "Plant farming". I tried it, it helps.

Of course, I do not use all the treatment recipes at once in one season. I choose the most convenient for me on this moment recipe. For example, this summer I resorted to a solution of baking soda and laundry soap (point 6). I watered my bushes before flowering and immediately after.
So I think that to choose one of the recipes and carry out two sprayings: the first before flowering, and the second right after, and this will be quite enough to defeat powdery mildew.

It must be said that among the gooseberries there are varieties that are resistant to powdery mildew.
And if you don’t want to get involved with this disease at all and spend your precious time on all kinds of spraying there, then it’s better to choose just such varieties and breed them in your area.
Here are some varieties that are resistant to powdery mildew:
"Kolobok" (tested in practice, this bush grows next to the local gooseberry, which is covered with white bloom every year, and at least he needs something without any spraying there)
"Ural grapes" (also tested the resistance of this variety to powdery mildew on personal experience)
"Kuibyshevsky"
"Grushenka"
"Finnish"
"Senator"
"Harlequin"
"African"
"Houghton"
"Masheka"
"Anniversary"

In general, it has been observed that thornless gooseberry varieties are almost not subject to powdery mildew. So when choosing a variety, you should pay attention to the presence or absence of thorns.

But there are varieties that are prone to powdery mildew:
"Seedling Lefora" (I get sick every year, I always have to spray)
"Date fruit"
"Triumphal"
"Golden Flame"
"Prunes"
"Russian"

One more useful rule- when buying seedlings, one must be very careful and not take those that are in doubt, covered with an incomprehensible coating and somehow do not look very good.

In conclusion, I would like to say that many plants suffer from powdery mildew - trees, flowers, vegetables. But, apparently, for each plant species there is some separate powdery mildew spore fungus, which spreads only on it and nowhere else. In other words, if your gooseberry is sick with powdery mildew, then, for example, cucumbers planted nearby will not become infected with powdery mildew from gooseberries. Gooseberries have their own powdery mildew, which is not transmitted to other crops, cucumbers have their own, flowers have their own, apple trees also have their own, etc.

Gooseberry pruning:

Pruning of gooseberry branches should be carried out one year after planting..

Only weak annual branches should be cut.

Annually it is necessary to leave no more than four or five strong branches.

All other branches should be cut to ground level.

In subsequent years, it is necessary to leave 3-4 good basal escape.

Mandatory Branches older than 6 years are subject to removal, which have a weak growth.

Most high yield berries can give branches aged 4-6 years. However, if the branch is older than this age, but looks quite healthy and strong, it is not necessary to cut it at all.

With proper care, it is able to bear fruit well for several more seasons, giving high yields.

If your gooseberry bushes are in running state, you can leave on them a few really strong and healthy branches, and cut off the rest.

Gooseberry pruning should be done early spring before bud break or late autumn. M can be cut branches growing inside the bush, if they thicken it and interfere with the development of other, stronger branches. Gooseberries perfectly tolerate forming anti-aging pruning.

It must be done in late autumn and only with bushes aged eight to ten years. It is necessary to cut off all the branches at the level of the soil, but do not touch the strong zero shoots.
