Spheroteca, or simply powdery mildew, appears in all its glory on gooseberry bushes in June. A white coating, similar to moss, covers the berries, leaves, shoots, mostly young ones. The disease can not only deprive a summer resident of his harvest, but also completely destroy the bushes. How to process gooseberries from powdery mildew in the spring, which means give a greater effect - these questions concern gardeners, experienced and beginners.
What kind of “chemistry” should I spray gooseberries with?
A fungus that overwinters well in the root zone, the causative agent of powdery mildew, awakens in the spring and quickly sheds spores, infecting neighboring plants and soil. Although the disease comes into full bloom at the beginning of summer, all preventive measures are 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 they must take measures to curb the spread of spheroteca and carry out preventive treatment of gooseberries. Experienced gardeners may notice signs of damage even before the buds open.
The following drugs are popular among summer residents in the fight against fungus.
- "Nitrophen". Spraying is carried out strictly until the buds open. For treatment, 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 people and pets. It is not used near bodies of water.
- "Tilt CE" - suitable for the prevention and treatment of already diseased bushes. It has the ability to penetrate the cells of the surface tissues of plants, which increases its duration of action. The emulsion for spraying is prepared at the rate of 0.4 ml of product per liter of water. The result is obvious within a couple of hours after use. The drug is not used if there is an apiary or fish ponds nearby.
Also used for treatment and prevention are “Emistar Extra”, “Vitaros”, “Skor”.
You can treat gooseberries before the buds open using proven means:
- copper sulfate – 80 g/10 l of water;
- iron sulfate – 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 shrubs, the products are sprayed onto 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.
To prevent or treat powdery mildew on gooseberry bushes, do not use colloidal sulfur, 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 unfavorable conditions.
Biofungicides
Gooseberry bushes are sprayed with biofungicides when daytime temperatures rise above 15°C. They can be used at all stages of the growing season. Planriz, Fitosporin-M, Pseudobacterin-2, and Trichodermin work effectively against powdery mildew.
Excess nitrogen in fertilizing increases the sensitivity of gooseberries to the pathogen.
Folk remedies for fighting spheroteca
The use of folk remedies in the prevention of disease is no less effective than the use of chemical or biological drugs. But the old recipes that came from the people are completely safe for people, birds, pollinating insects and other inhabitants of the garden plot.
The peculiarity of using folk remedies on gooseberries is that the bushes are not sprayed, but each shoot is generously moistened.
- Watering with boiling water
The procedure is carried out as soon as the snow melts. All debris is first removed from under the bushes. Exposure to temperatures above 60°C is detrimental to spheroteca spores; 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 (moths, aphids, sawflies, snails, slugs). At the same time, it serves as a supplier of calcium, potassium, phosphorus, and reduces soil acidity.
For spring processing, take dry ash and sift it. Dusting of bushes is carried out at the rate of 15-20 g per bush. At the same time, the ash is poured into the soil under the root (300 g/m2) when digging, spilled with water, and dry soil is sprinkled on top.
During the spring, four or five more treatments of gooseberries with ash are carried out, but in liquid form. The infusion, prepared at the rate of 300 g of ash per liter of water, is kept for 5 days, then the bush is generously sprayed.
- Soda Ash
Before flowering begins and immediately after its completion, gooseberry bushes are treated with a soda solution. First, dilute 50 g of the product in boiling water, then add water to a volume of 10 liters, add 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. Treatment of gooseberries begins from the moment the buds open and is repeated every 2 weeks.
Brilliant, common in a home medicine cabinet, also helps get rid of fungus. Add 2 drops of antiseptic to a bucket of water and spray the gooseberries.
- Mullein
The solution for treatment is prepared as follows: 1 part of rotted manure is diluted with 3 parts of water, left for 3 days, filtered, and 3 parts of water are added to 1 part of the infusion. The product is suitable for treating plants before and immediately after flowering. Rotted hay or straw is used in the same way.
- Whey, kefir or sour milk
A liter of dairy product is diluted with 9 liters of water. Spray on young leaves three times a week. 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, allowed to brew for 2 days, filtered, and the husks are squeezed into an infusion. Treatment is carried out before flowering begins and after it ends.
- Tansy
Dry leaves and flowers (300 g) pour cold water(10 l), leave for 2 days. Simmer over low heat for 3 hours, filter. The resulting solution is sprinkled on the ground under the bushes after spring digging.
- Horsetail
100 g of dry herb is soaked in 10 liters of water, after a day of infusion, it is boiled over low heat for an hour. The cooled broth is diluted with water 1:5. Horsetail is used to treat gooseberries from early spring until the end of leaf fall.
Spraying gooseberries with fertilizers immediately after the end of flowering performs two functions simultaneously: it feeds the bush leaf by leaf and prevents infection with powdery mildew. A 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 against powdery mildew?
The first treatment of gooseberry bushes is carried out strictly until the buds open. To do this, select a chemical fungicide or folk remedy, including watering hot water. The period 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 is after flowering is completed. Use biofungicides or traditional methods.
Shrubs are processed in the following order:
- To carry out the procedure, choose a dry, cloudy, windless day or the early evening hours of a sunny day.
- Carefully spray the crown, making sure that the product is sprayed on both sides of each leaf - top and bottom.
- The side parts and base of the bush are treated in the same way.
- Water the soil under and around the gooseberries with the medicinal solution.
It is advisable to simultaneously treat plants and soil in nearby beds.
Agrotechnical techniques
It is difficult to achieve a sustainable positive result by treating shrubs alone. It is also important to follow the simplest agrotechnical rules:
- thinning the bush, timely cutting out old branches that produce few berries;
- maintaining cleanliness under the bushes, regularly removing debris;
- refusal of nitrogen fertilizers.
Some gardeners successfully use dry remains of garden and vegetable plants to combat the pathogen of powdery mildew. The trunk circle is covered with tops and watered with a solution of the EM preparation. Beneficial microorganisms happily feed on the spores and mycelium of the spheroteca.
A positive result in curbing the spread of spheroteca spores is obtained by sowing doctor plants under the bushes - garlic, marigolds (tagetes), dill, parsley, mint. The first two also protect plants from pests, flowering marigolds and spices attract beneficial insects.
Protecting gooseberries from powdery mildew is a constant process; the lightest spores are regularly carried by the wind. Spring treatment of bushes protects berry bushes from pathogens introduced in the fall. In order to fully protect the garden from the sphere library, you need to constantly monitor the condition of the bushes, prevent them from shading or thickening, spray them with an optimally selected composition in due time, and cut out shoots with signs of damage with a firm hand. Compliance with the entire set of measures will preserve the harvest of gooseberries and the health of all plants on the site.
On gooseberries. These berries are often affected by this disease. You can’t eat them, the harvest is lost, and this could happen again every year. The fight against powdery mildew on gooseberries should be carried out systematically and thoroughly. So, powdery mildew on gooseberries - measures to combat it and preventive measures.
What does powdery mildew look like on gooseberries?
Gooseberries affected by powdery mildew look like this: gooseberry shoots and lower leaves covered with a white coating. The coating is velvety in appearance and dry. One gets the impression that the bushes were sprinkled with flour. If you shake the branches, the plaque remains in place, but you can remove it with your fingers if you rub it thoroughly.
The spread of plaque is rapid, throughout the entire bush. The upper foliage and branches are affected very quickly, but the berries turn white last resort. Over time, the plaque becomes darker, acquiring a brown or dirty gray tint. The disease is caused by fungal spores carried by wind and insects. If moisture is constantly maintained and heat air is ideal conditions for the development of powdery mildew.
Other factors contribute to the onset of the disease:
- There is a lot of nitrogen in the soil.
- Gooseberries are planted close to crops susceptible to powdery mildew: grapes, currants.
- Nutrient poverty of the soil.
Folk remedies for powdery mildew on gooseberries
Treatment of gooseberries for powdery mildew folk remedies must be safe for people and plants. There is no need to use sulfur as a control measure, because you can simply burn the leaves and bark of the gooseberry; it is better to use other methods. Eg:
- Making and spraying with soda solutions.
- The use of copper sulfate.
- Using solutions of potassium permanganate and ash.
- Treatment with onion peels and tansy decoction.
There are other compositions that are used by gardeners in practice. When carrying out work, even with folk remedies, do not forget about gloves, in order to avoid burns and allergic skin reactions. It is better to start all treatment activities at the initial stage of the disease, avoiding global infection.
Soda for powdery mildew on gooseberries
Soda ash for powdery mildew on gooseberries is used as follows:
- Dissolve soda in a small amount hot water and stir to form a paste.
- Add water to a volume of 10 liters.
- Add 10 grams of liquid soap (laundry or tar).
- The bush is treated before flowering begins, the second treatment is carried out before the fruit appears.
You can prepare the solution according to another recipe: add 60 grams of soda to 10 liters of water, 10 aspirin tablets, 10 grams of liquid tar soap. Spraying is carried out every 7 days 2 times. Each gardener decides for himself how to combat powdery mildew on gooseberries using soda.
Iodine for powdery mildew on gooseberries
Treatment of gooseberries with iodine for powdery mildew is carried out as follows:
- Take 1 liter of whey
- Add 2 drops of iodine.
- The resulting composition is sprayed with gooseberries at intervals of 3-4 days.
Preparations for powdery mildew on gooseberries
Preparations against powdery mildew on gooseberries are divided into 2 types: biological and chemical. Chemical ones act faster, but if time has been lost and fruits have already formed on the gooseberries, it is better to use the safest ones, which are included in the biological category. Both types of disease are effectively treated. Among the most common drugs are:
- topaz;
- trichopolum;
- baktofit;
- haupsin;
- nitrophen.
Fitosporin against powdery mildew on gooseberries
Fitosporin is a biofungicide with a broad spectrum of action. It is based on bacteria that slow down the growth of fungus. It can be used as a prophylactic and at the initial stage of gooseberry disease with powdery mildew in the form effective measure struggle. Before processing, you should carefully read the instructions for use.
Fitosporin against powdery mildew on gooseberries is used as follows: 100-150 ml of the drug is diluted into a ten-liter container of water. The bushes and the soil under them are treated in the spring before the flowering stage begins, and also in the fall after the end of fruiting. In addition to destroying the fungus, phytosporin significantly increases plant immunity.
Topaz for powdery mildew on gooseberries
Topaz is a systemic fungicide, it is an excellent treatment fungal diseases on different cultivated plants, gooseberries are no exception. The use of topaz against powdery mildew on gooseberries is as follows:
- For 10 liters of water take 2 ml of Topaz.
- Stir the working solution thoroughly.
- The composition is used once and cannot be stored.
The protective effect of the drug lasts 8 to 18 days, depending on how quickly the disease develops. To spray 1 adult gooseberry bush, you need an average of 1.5 liters of the composition. Spray the plants once every 14 days. Ideally, at least 20 days should pass from processing to harvesting the berries.
Trichopolum for powdery mildew on gooseberries
Trichopolum is a drug whose main active ingredient is metronidazole. Gardeners claim that Trichopolum for powdery mildew on gooseberries is effective as a measure to combat infection. Treatment can be carried out in two ways: spraying and watering. Spraying is more effective, the drug acts faster.
Dosage for working solution: 1 tablet of trichopolum per 1 liter of water. Spray the bushes in dry weather, towards evening. Before dissolving, the tablets are crushed into powder so that they dissolve faster. It must be remembered that there have been no specific studies of the mechanism of action of the drug in the field of agronomy, so it is worth remembering safety measures and avoiding contact of the solution with mucous membranes and skin.
Downy mildew on gooseberries - control measures
When infected with downy mildew, gooseberry leaves shrivel and turn brown. Once dry, pieces of leaves can infect healthy gooseberry bushes. If the disease is detected at the initial stage, it is still possible to fight it, but many summer residents solve the problem more radically: they destroy the affected gooseberry bushes and do not use other control measures.
Downy mildew on gooseberries differs from ordinary mildew in that it affects not only the leaves, but also the growth buds; only the petioles remain free. The disease spreads due to frequent evening watering, heavy morning dew, excess nitrogen and lack of phosphorus. As a control measure, the affected parts of the gooseberry are removed and burned; the berries should be treated similarly.
Prevention of powdery mildew on gooseberries
It is important for gardeners to learn not only about methods of treating the disease, but also about how to prevent powdery mildew on gooseberries. Prevention - The best way not only reduce the likelihood of infection, but also avoid it altogether. Powdery mildew on gooseberries - control measures in the form of prevention:
- Prune bushes in spring and fall. Remove diseased and old shoots and burn them.
- IN spring period remove all fallen leaves from last year from under the gooseberry bushes, after which it is better to dig up the soil.
- In early spring, gooseberry shoots are doused with hot water (temperature about 90 degrees). You can add potassium permanganate or baking soda to the water. This control measure should not be abused; a single treatment is enough.
- The resistance of gooseberries to powdery mildew can be increased by applying potassium and phosphorus fertilizers, for example, extract from wood ash.
Experts recommend starting measures to combat the right choice places for planting gooseberries. It is worth keeping a distance between the bushes so that the soil dries out and is ventilated. Previous crops should definitely be taken into account; you should not plant raspberries and currants next to each other. An important preventive measure can also be called increasing the gooseberry’s immunity and increasing its resistance to various types of diseases.
Powdery mildew on gooseberries is a disease, control measures for which must be effective and systemic. The meaning and effectiveness of health activities. In some cases, it is easier to destroy diseased plants than to allow them to infect all gooseberry plantings in full.
(c) Katerina Shlykova
Powdery mildew- one of the most dangerous diseases for gooseberries. It can destroy the entire crop, and in a few years the plant itself. In addition, powdery mildew is a common disease, the distribution area of which is very wide. The spores of this disease develop especially actively in warm and humid weather.
If late May - early June examine the gooseberry bushes, you can find leaves, young shoots and already established berries this is such a loose (mealy) coating white:
Apparently due to appearance and the name of the disease - .
In the future this the plaque becomes denser, darkens, turns brown, crust-like:
Affected shoots become twisted and eventually dry out. Affected leaves curl, become brittle, and stop growing. The affected berries do not have time to ripen; they simply crack and fall off the bush green. The result of such a disease is the lack of harvest and young growth, and within a few years the death of the entire plant.
Powdery mildew (or spheroteca) is a fungal disease that begins to spread in the spring with the onset of warm weather through spores. By the way, this disease comes from America, so it is often called “American powdery mildew” in the literature. Well, again, trouble is upon us from the American continent. Colorado beetles are not enough for them. Actually, as has already been said, this is a really bad disease that you should not ignore. But despite all its seriousness, powdery mildew is quite easy to combat.
Two directions of action can be distinguished here - agrotechnical and chemical, which give good results in aggregate.
For those who in no way accept the use of chemicals on their site, agrotechnical methods (including folk recipes) may be quite sufficient. But if the disease is still too rampant or the gooseberry plantations are extensive, then, perhaps, you should not give up chemicals. Moreover, literally one spraying with them is enough, while folk recipes will have to be resorted to not two or three times a season, but more, especially if warm and humid weather contributes to the spread of powdery mildew.
PREVENTION of powdery mildew:
1. Bush pruning gooseberries in autumn or in early spring promotes good development bush and helps resist various diseases, incl. and powdery mildew. During pruning, be sure to remove 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) detected disease-infected shoots and berries if possible delete. It is believed that the disease spores overwinter on affected shoots, and sometimes on fallen leaves. Therefore, in early spring, last year’s foliage should be removed from under the bushes.
3. In early spring, when the snow had just melted around the bushes and the threat had passed severe frosts, but strictly BEFORE kidney swelling, good pour hot (+90) water over the gooseberry bushes. In such water you can dissolve potassium permanganate until Pink colour or soda (1-2 tablespoons per 10 liters of water). Such a “hot shower” is good as a preventive measure against many fungal diseases, and black currant They say it also helps against spider mites.
4. Use only as fertilizers potassium(which includes, for example, ash) and phosphorus. They contribute to the resistance of gooseberries to powdery mildew disease. But it is better to refrain from nitrogen fertilizers. Nitrogen can cause the shoots to not have time to ripen and, as a result, to be more affected by powdery mildew.
It is useful to use these methods of prevention in combination.
RECIPES FOR TREATING powdery mildew with chemistry and folk remedies:
1. In early spring BEFORE the buds swell For gooseberries, spray the bushes and the litter around them (last year's grass, leaves) with a 1% solution of copper sulfate (100 grams of copper sulfate per 10 liters of water).
2. In magazines and literature it is recommended to use chemical drug"Topaz" (according to instructions). Spray with this solution twice if necessary - BEFORE flowering and immediately AFTER flowering. You can get by with just one spray - immediately AFTER flowering. I have tried this drug in practice and can confirm its effectiveness.
3. An excellent drug for combating powdery mildew is "HOM". This is a kind of Bordeaux mixture substitute. Bushes sprayed HOM solution (0.4%, i.e. 40 g 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 included with the drugs) and also dilute them in a small amount of water. Then mix these two solutions together and bring 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 grated on a grater with large holes. Copper sulfate is first dissolved separately in hot water, and then poured in a thin stream, stirring constantly, into the soap solution. room temperature. The resulting soap-copper emulsion should be bluish in color, uniform in consistency, without flakes falling out. Spray IMMEDIATELY AFTER FLOWERING, or in the worst case, immediately after setting the berries.
5.
Here are a number of other drugs recommended in various literary sources (though I have not tried them): “Vectra”, “Skor”, “Cumulus”, “Abiga-Peak”, colloidal sulfur.
"Tiovit Jet" (20-30 g per 10 liters of water) is characterized, like other sulfur preparations, by a protective and infection-eradicating effect on initial stages development of powdery mildew. It is also used on currants.
6. 50 g of soda (2 tablespoons) + 50 g of laundry soap per 10 liters of water. The soap is grated on a grater with large holes. All this is thoroughly dissolved in water. I do not spray the bushes with this solution, but water it directly from a watering can through a strainer attachment, and also water the ground around the bushes. Good prevention. This procedure must be done BEFORE flowering as soon as the leaves began to bloom, and IMMEDIATELY AFTER FLOWERING. If necessary, you can repeat the procedure 2 more times with an interval of 7-10 days.
7. The daily infusion of ash is 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 messing around with ash this way. And besides, for me, ash is primarily important as a fertilizer for cabbage, strawberries, onions and other crops. Therefore, I do not use it to treat gooseberry powdery mildew. Note - one liter jar holds 500 grams of ash.
8. And another way to combat powdery mildew. Take 200 grams (1 glass) of urine and dilute it in 5 liters of water. The resulting solution is immediately sprayed onto the bushes. This spraying is carried out immediately AFTER the gooseberries bloom. 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 Homestead magazine. I tried it, it helps.
Of course, I don’t use all the treatment recipes at once in one season. I choose the recipe that is most convenient for me at the moment. For example, this summer I resorted to a solution of soda and laundry soap (point 6). I watered my bushes before flowering and immediately after.
So I think that I should choose one of the recipes and carry out two sprayings: the first before flowering, and the second immediately 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 waste your precious time on all sorts of spraying, then it’s better to choose just such varieties and breed them on your site.
Here are some varieties that are resistant to powdery mildew:
"Kolobok" (tested in practice, a bush of this variety grows next to the local gooseberry, which every year is covered with a white coating, and "Kolobok" is fine without spraying)
"Ural grapes" (the variety's resistance to powdery mildew was also tested personal experience)
"Kuibyshevsky"
"Grushenka"
"Finnish"
"Senator"
"Harlequin"
"African"
"Houghton"
"Masheka"
"Anniversary"
In general, it has been noticed that thornless gooseberry varieties are almost not susceptible to powdery mildew. So when choosing a variety, you should pay attention to the presence or absence of thorns.
But there is varieties that are susceptible to powdery mildew:
"Lefort seedling" (I get sick every year, I always have to spray)
"Date fruit"
"Triumphal"
"Golden Light"
"Prune"
"Russian"
Another useful rule - when buying seedlings you need to be careful and do not take those that raise doubts, are covered with an incomprehensible coating and look dubious.
In conclusion, I would like to say that many plants suffer from powdery mildew - trees, flowers, vegetables. But, apparently, for each type of plant there is a separate fungus-spore of powdery mildew, which spreads only on it and nowhere else. In other words, if your gooseberry gets powdery mildew, then, for example, cucumbers planted nearby will not get powdery mildew from the gooseberries. At least this is what happens in my garden. 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.
Have a rich harvest and may your gooseberries never become covered with a white coating!
Always with you,

Gooseberries are popular among people due to their taste and health benefits. Just collect from it good harvest It doesn't always work out. This is due to powdery mildew, which constantly plagues gooseberry bushes.
Old varieties, which are the most delicious, are especially susceptible to the disease. Below we will look at how to treat gooseberries against powdery mildew in the spring, preventing damage to the berries and death of the bushes. The main thing is not to waste time by carrying out spring treatment.
Indeed, if powdery mildew is not combated, it can completely destroy the crop, and within a few years the bush may even die. This is a fungal infection, which is officially called spherotheca.
It first infects young shoots and leaves, then spreads to fruits, and then spreads to perennial branches. Parts of the bush are covered with a white coating, which after some time becomes brown and even brown. Flowers begin to crumble, leaves wither and curl, berries do not develop, branches bend and dry out.
The fungus spreads through the air or through insects. At the end of May, the disease already becomes visible. Comfortable conditions Warm and humid weather is considered to breed the infection. This disease has already adapted to our weather conditions, so it tolerates cold well.
Spores persist on fallen leaves and shoots.
But don’t be discouraged if you notice this disease on your bushes. You can fight it quite successfully. The most important thing is not to delay treatment indefinitely.
When is the best time to carry out treatment?
To prevent the appearance of powdery mildew on the bushes, as well as to destroy existing spores, it is recommended to carry out 4 treatments of gooseberries:
- Before the buds begin to bloom. It is better to do this with hot water, as described below.
- Before flowering, along the green cone.
- Immediately after flowering.
- Autumn treatment that needs to be done before leaf fall.
If it was not possible to prevent the disease using preventive spraying, you should take action immediately after you notice the first signs of the disease.
Ready-made preparations for spraying gooseberries
There are many drugs that can cure plants from powdery mildew. We will distinguish 2 categories: chemical and biological products.
Chemical
It is believed that the use of chemicals helps to quickly get rid of the disease.
However, when the fruits have already formed, it is better to use safer means:
- Nitrophen. 200 g of the drug are diluted in 10 liters of water. The bushes are processed strictly on bare shoots, until the buds open. The solution cannot be used if the buds have started to grow, as this can lead to their death.
- A solution of one of the following fungicides: Topaz, Fundazol, Thiovit-Jet, Tilt, Vectra or the like. It is advisable to treat gooseberries with these preparations twice: before and after flowering. The proportions of dilution with water should be found on the packaging of each of these drugs.
Copper based
These include big number ready-made compositions, which are diluted with water before use. For example, Hom, Oxychom, Copper oxychloride, copper sulfate etc. They are diluted with water in accordance with the instructions.
You should know! Preparations containing copper can only prevent the development of the disease, but they are not able to cure an existing disease. This is an excellent plant protection, but not a cure.
The fact is that the mycelium of powdery mildew live inside the cells of the plant, and only its spores are on the surface. Copper cannot reach the mycelium. Therefore, the best result gives spring treatment gooseberries with these substances.
Colloidal sulfur
The effect of sulfur on a fungal infection is that, penetrating inside the fungus, sulfur combines with hydrogen molecules and displaces oxygen. The mycelium, not receiving oxygen, dies.
30-40 g of sulfur are diluted in 5 liters of water. The prepared solution must be used immediately, on the day of preparation, as it is not stored for a long time. Sulfur is not mixed with other drugs, but is used only in its pure form.
Important! Colloidal sulfur can be used in the temperature range from +20 to +35 degrees. At higher temperatures, burns and leaf fall are likely.
The protective effect of sulfur lasts 10-14 days. It is recommended to use it no more than 3 times per season, but last treatment It is advisable to carry out no later than a week before harvesting. If the bushes have previously been treated with other pesticides, then before using sulfur you must wait 2 weeks.
Biological products
Let's list some of the dozens of possible options.
These products have been tested in practice and have a positive effect in the treatment of powdery mildew:
- Gaupsin. It is a concentrate. To prepare the solution, 150 g of the drug are diluted in 10 liters of water.
- Fitosporin. Available in powder, liquid or paste form. An aqueous solution is prepared, which is used for processing.
- Baktofit. This is a broad-spectrum biological product produced in powder form.
- Trichodermin. Available in powder form. Before use, dilute 10 g of powder in 5 liters of water.
Biological products contain colonies of microorganisms that feed on fungal spores.
The positive qualities of biological products are that they are safe for humans and plants, and plants can be sprayed with them at any time. Flaw - a short time actions. For example, Gaupsin is valid for only 15 days. True, during this period he manages to cope with fungi. Biological products cannot be combined with copper-based substances.
Folk remedies for processing gooseberries
Below will be given traditional methods combating powdery mildew on gooseberries.
Wood ash
Ash effectively destroys fungal spores and prevents the appearance of aphids, caterpillars and slugs on plants. In addition, it is a supplier of phosphorus, calcium and potassium, which are necessary for plants.
1 kg of sifted wood ash (2 liter jars) is infused for a week in 10 liters of water. The solution is filtered so that the sediment remains at the bottom, and then the bushes are treated with it at intervals of several days.
Multiple treatments are allowed throughout the season. But it gives the best results when used in early spring. Provided full compatibility with any substances. Ash is harmless to plants and humans.
Potassium permanganate solution
Approximately 1.5 g of manganese is taken per 10 liters of water. The bushes are processed twice: before and after flowering. Be sure to spray the tree trunk circles under the gooseberries with potassium permanganate to disinfect them. If manganese is applied in time, the disease can be stopped completely.
Infusion of mullein or rotted hay
Take 1 part of rotted manure or hay and dilute it in 3 parts of water. The mixture is infused for 3 days and then filtered. For getting ready solution you need to add another 9 parts of water and spray the gooseberries. Microorganisms that actively develop in rotted manure or hay feed on the fungus and destroy it. Treatments can be repeated every 10 days.
Baking soda
Used in combination with laundry soap. 50 g of soap is pre-grated and poured into a bucket of water (10 l). After dissolving it, add 2 tablespoons of soda to the water. The solution is used for spraying bushes or for irrigating them using a watering can. The procedure must be done before flowering, and then after flowering.
Whey, kefir, skim milk, milk
Any fermented milk product, when applied to leaves or shoots, forms a strong oily film on their surface, blocking the access of oxygen to the mycelium. As a result, the fungus dies.
The dairy product is diluted with water in a ratio of 1: 10. Plants are sprayed only in dry weather, several times, at intervals of 3 days. Increasing the number of treatments only benefits the plants, as the gooseberries receive additional nutrients.
Horsetail decoction
Both fresh and dry herbs are suitable for preparing a decoction. You need to take 1 kg of fresh grass, and 100 grams of dry grass. The grass is soaked in 10 liters of water for a day, after which it is boiled for 1 hour. The infusion needs to be cooled and diluted with water in a ratio of 1:5. Now you can spray the bushes.
Attention! Horsetail decoction can be stored for no more than 7 days.
The decoction can be used repeatedly throughout the season.
Decoction of tansy flowers
In order to prepare a decoction, you should take 300 g of fresh or 30 g of dried tansy flowers, leave for a day in a bucket of water, and then boil for 1 hour. No need to dilute. Use for treating bushes and the ground under bushes.
Onion peel
200 g onion peel need to be soaked in a bucket of hot water for 2 days. After straining it can be used. Repeated processing of gooseberries is allowed throughout the season.
Prevention
If you carry out preventive measures with gooseberry bushes during the season, you can significantly reduce the likelihood of infection:
- Bushes are pruned in early spring and autumn. Old and diseased shoots are removed, which contributes to better development of the bush. Diseased branches must be burned.
- In the spring, you should remove fallen leaves under the bushes on which the fungal spores overwintered. After this, the soil under the bushes is dug up.
- In early spring, before the buds open, it is recommended to carry out a very effective procedure. Gooseberry shoots are doused with hot water at a temperature of 90 degrees. Hot water destroys spores not only of powdery mildew, but also of many other fungal infections. For getting best result You can add baking soda to the water (2 tablespoons per bucket of water) or a diluted solution of potassium permanganate. Only one-time treatment of bushes with hot water is allowed!
- Gooseberry resistance to powdery mildew increases when phosphorus and potassium fertilizers are applied to the bushes. Extract from wood ash is an excellent way not only to feed the bushes, but also to protect them from the spherote. But it is better not to use nitrogen fertilizers. The shoots may not ripen by autumn, which will increase the likelihood of their infection.
- Planting dill, garlic, and blackbrows near gooseberries reduces the likelihood of infection.
Precautionary measures
Treatment of plants with topaz, colloidal sulfur or other fungicides should be carried out wearing protective equipment. It is also advisable to use a respirator or gauze bandage. If drugs come into contact with the skin or eyes, to avoid burns, rinse these areas with plenty of water.
It is recommended not to use any one drug, but to alternate them. This way you will be able to avoid the mycelium becoming addicted to any one substance. Also, you can choose the most effective and convenient options for treating powdery mildew.
The fight against powdery mildew should be carried out in a timely and complete manner, in several stages. In this case, it is possible to avoid the onset of the disease, as well as completely get rid of the manifestations of the disease.

How to prevent the development of the disease?
And of course, we must not forget about prevention.
- Be sure to spend the autumn or spring pruning bushes, and remove infected shoots and burn them outside the site.
- Inspect the bushes in spring and summer for the presence of infected shoots and leaves and, if found, remove them immediately.
- Before winter and early spring, carefully collect leaf litter under bushes, since powdery mildew spores can safely survive the winter in fallen leaves.
- In the spring, before the buds begin to swell, pour boiling water over the bushes - this is an excellent prevention of not only powdery mildew, but also other fungal diseases.
- It is advisable to fertilize the crop with potassium and phosphorus fertilizers and try to refrain from using nitrogen fertilizers, since the former increase resistance to powdery mildew, and the latter often do not allow the shoots to fully ripen, which leads to severe damage by this disease.
It is advisable to combine preventive measures and apply them comprehensively. Have a good harvest!
