Gooseberry berries have a bright, unique taste and contain a huge amount of vitamin C. The appearance of white bloom on the shrub may indicate the presence of powdery mildew on the plant. This type of fungus develops rapidly, infecting other plants, may eventually destroy them. Therefore, you should find out how to deal with powdery mildew on the gooseberry and when to prevent it.
How to recognize powdery mildew
Mealy dew is a fungus of the sphere library, which spreads through spores, falling on vegetation from neighboring plants that are sick of them. It affects not only gooseberries, but also currants, cucumbers and other crops. Wet weather and temperature equal to 17-28 degrees contribute to its development.
The main symptom of powdery mildew is a whitish-gray patina on fruits and leaves. It is quite thin and looks like dust at the beginning of the disease, but over time it becomes denser, begins to blacken. Small brown balls appear on the surface of the leaf - these are the fruit bodies of the mushroom-sphere library. Powdery dew can be seen already in the period of blooming of the plant, then on ripening berries and new shoots.
How powdery mildew spreads
Leaves that are sick begin to dry out, and the processes become crooked at the ends, darken and die. Most often the disease affects the leaves and shoots that are near the ground. But over time, the infection rises gradually higher and infects the whole plant. If you do not figure out how to deal with powdery mildew on the gooseberry, if the berries have already appeared, then they will crack and rot.
In winter, the sphere is located on the tops of the gooseberry shoots of the current year. The development of the fungus promotes favorable conditions during which an active spore release occurs. Further, the disease spreads throughout the plant, depressing its vital activity. Affected bushes become crooked and stop developing. Powdery mildew should be combated, both on the gooseberry, currant, and other plants that are susceptible to this disease.
Factors affecting the development of powdery mildew
The mildew fungus begins to spread under high humidity in warm weather. The most favorable conditions for its growth is moderate air temperature, while the humidity should be about 90%. During hot days, when the thermometer shows values above 28 degrees, the fungus slows down and begins to die.
The degree of development of powdery mildew strongly depends on the climate in the season when it appears on the plant. This is due to weather conditions that may vary over several years. In the period from two to three days to a week, the disease affects all young growths and ovaries. In the hot year, when there is little rain, spores of the fungus do not develop well, so gardeners can rejoice at the rich harvest of gooseberries.
Powdery mildew is affected by the following factors:
· The use of some soil disintegrators for growing plants,
· The distance between gooseberry bushes,
· Excessive watering, etc.
Mealy dew faster and more abundantly affects plants that grow in low areas of the garden. The soil there breathes worse, and water often collects in the lowlands, which is the ideal conditions for development for the fungus.
Summer residents themselves can also provoke outbreaks of the disease on their vegetation. They can pour gooseberry bushes heavily and also use dark materials as mulch. When using such agrotechnical methods, the humidity and temperature of the air directly near the plant increase, which has a beneficial effect on the fungus and its reproduction.
Also some insects can be the cause of the disease. Leaves that have been eaten or dried, become most vulnerable to fungus. The appearance of a large number of shoots can cause excessive thinning and improper pruning.
How to deal with powdery mildew on gooseberry
In order to get rid of the powdery mildew, first of all you need to cut off all the sick parts and burn them. If this is not done, then they will accumulate a large number of malicious disputes, in the spring they will infect new branches, as well as other shrubs. It is important to know how to deal with powdery mildew on gooseberry fruit. In case of illness, plants are treated with fungicides at least one month before harvesting.
Why powdery mildew appears
Powdery mildew spores are always in the soil. They are found extremely rarely, because they begin to manifest themselves only in certain conditions. With sunny and warm weather, good watering and feeding of plants, the fungus in rare cases can hit the shrub. When the temperature drops to 12-15 degrees, which lasts for some time, powdery mildew actively begins to manifest itself.
So, we select the main factors that contribute to the infection of plants:
· Damp, cool weather with high humidity about 80%,
· Excessive nitrogen content in the earth,
· Too densely planted plants,
· The soil was first strongly dried out and then flooded with water,
· Watering the plant occurs even if the top layer of the earth has not dried yet after the previous irrigation.
Such conditions are favorable for the fungus spores, in which case they wake up and may infect other plants. It is worth noting that they are able to quickly transported with the help of wind or water. Another variant of their distribution is the gardener's clothes and skin, which, when touching an infected plant, transfers the disease to a healthy one.
What activities are carried out in the fight against fungus
The easiest time to carry out preventive measures than to engage in the treatment of gooseberry powdery mildew. Strict compliance with certain rules will help get a good crop of berries. Begin to fight with powdery mildew on gooseberries, both in autumn and in early spring.
Anti-fungal activities are divided into:
· Natural and chemical means for external processing,
Such measures are aimed at improving the plant’s own protective capabilities, as well as at the fastest maturation of their integumentary tissues.
In order to avoid the appearance of powdery mildew it is necessary:
· Periodically thin out plants,
· Tearing the lower leaves as they come into contact with the ground,
· Water the plants when the ground is well dried,
· Not to get involved in nitrogen fertilizers,
· Feed plants with potassium phosphate mixtures.
In early spring, before the trees bloom buds, gooseberries are poured with boiling water. Conduct this procedure instantly using a watering can. They pour branches completely, not lingering on one of their sections. Such a rapid effect of boiling water will not damage the plant, but the powdery mildew spores will have time to die. You can also use a household steam cleaner.
Powdery mildew treatment
To effectively cure the disease, you should remove the mycelium and spores of the fungus.
How to deal with powdery mildew on gooseberries?
· Stop all spraying,
· Not to feed those gooseberry bushes, where the fungus is already showing,
· Make the best possible plant lighting,
· Thin out planted bushes, get rid of dried leaves and branches,
· In plants planted in pots, the top layer of soil must be renewed,
· Pour or spray the gooseberries and the ground around it with a fungus agent.
You can use special tools or self-made substances.
Powdery Mildew Chemicals
Topaz-fungicide, which is often used in the treatment of various fungal infections - is the tool most used by gardeners. Its main active ingredient is penconazole. For spraying gooseberries, dissolve 1 ampoule in 10 liters of water and 5 liters for flowers. Apply only fresh solution, evenly distributing it throughout the plant. Treat every 2 weeks, because its protective properties after this time ends. Topaz is dangerous for fish and is moderately toxic to people and animals.
Tilt CE - systemic fungicide, which is used as a medicine and fungal prevention. The active ingredient is propiconazole. It is a concentrated emulsion. The tool is able to suppress the formation of fungal spores, which prevents the development of the disease. It can get into the tissue of the plant, which makes it moisture resistant. It has a high duration of action, at elevated temperatures the effectiveness of the agent is enhanced.
The emulsion is prepared shortly before processing at a concentration of 0.4-0.5 ml. per liter of water. It should not be used at temperatures above 29 degrees and humidity less than 60%. The tool protects plants for about 3 weeks, and a noticeable result occurs within 2 hours. The drug provides danger to fish and bees.
Before you deal with powdery mildew on gooseberries, you should take into account that the disease is fungal in nature. 3 methods of plant treatment are used: agrotechnical, chemical, and also agrochemical. When using the first method, you should immediately cut the places where the fungus accumulates, as well as do the planned pruning of the shoots before the beginning and at the end of the growing season of the plant. It is better to do a preliminary prevention of such a phenomenon as powdery mildew of gooseberry. Fighting the disease in the spring is not early; with the arrival of heat, it is necessary to begin to free the bushes from damaged and old branches, and the ground from last year’s foliage.
It should be borne in mind that mushrooms form spores 2 times a year. Therefore, the gooseberry must be processed before and after its flowering, as well as when autumn comes. It is better to perform the procedure in the evening, generously watering the whole plant and the soil under it. To do this, use a wide-spectrum sprayer, carefully irrigating the wrong side of the leaves of the gooseberry. Before dealing with powdery mildew on the gooseberry, it is necessary to remove its affected areas even before the plant is processed.
If the shoots are formed correctly, they will be strong and will be able to resist the powdery mildew. It is necessary to feed gooseberries with potash and phosphate fertilizers. Avoid the use of nitrogen supplements, they inhibit the growth of shoots, which leads to their defeat fungus. If you have suffered a large area with plants, then you need to use strong chemicals.
To begin to deal with powdery mildew, both on the gooseberry and other plants, it should be even with the onset of spring. Using natural methods or chemical means, you should regularly treat them bushes. Also, experienced gardeners recommend timely treatment of the disease and its periodic prophylaxis. It is necessary to combat the powdery mildew on the gooseberry, both in June and autumn, after the completion of active growth of the plant.
What is powdery mildew?
Its scientific name is sphere library. This is a fungus that affects not only gooseberries. It is often found on currants, vegetables, flowers and trees. The causative agent is a marsupial fungus, belonging to the family of powdery mildew. Its disputes are able to calmly survive the winter on the fallen leaves in the fall, infected branches. When at the beginning of spring the temperature of the air rises above seventeen degrees of heat, the mycelium bursts, the ascospores fly away.
What is powdery mildew dangerous?
Spraying occurs twice a year. In the spring, when the plants appear buds, the first leaves. In the summer season, when favorable conditions are created for this. And these are frequent rains and, as a result, prolonged high humidity of the soil, air, in the atmosphere no higher than twenty-six degrees. In addition, there are other reasons:
- Bushes are densely planted, which means that they are poorly ventilated,
- poor, organic soil unaffected,
- poor care made more than urea, nitrogen fertilizer, manure,
- there is a cardinal pruning.
All this greatly reduces the immunity of the plant. But if you properly care, apply potash fertilizers to the earth, the plant will avoid infection. Moreover, even if the weather contributes - the optimum air temperature is above thirty degrees, arid, hot summer, then there will be no disease, its development will stop completely.
How to recognize this disease?
In May and June, each gooseberry bush should be carefully examined. Infection occurs when the ground is warm enough, and the weather is often rainy. It is easy to recognize, the main thing to notice in time.
Signs of presence of a sphere library:
- On the ovaries, and after and on the berries, a spotted white bloom appears, then it forms a creamy film, which when dried becomes a thick, brown crust, affecting their entire surface, gradually turning to leaves, shoots, they turn brown
- the upper part of the branches turns yellow, then darkens, bends
- leaves, affected by a light loose coating, wither, then curl
- the shape of the fruit changes, they become small, cracked, brown in color, not sufficiently developed, dried out and not ripening, fall down.
It is necessary to get rid of the fungus as early as possible. Gooseberry, other plants located on the site will be saved and capable of high yields. Otherwise, the disease will affect the gooseberries, nearby neighbors - raspberries, currants, strawberries. Insects can transfer it to pumpkin vegetables (cucumbers, squash, zucchini).
It is undesirable to poison such a useful plant with chemical preparations, because the fruits ripen quickly, and other methods can not always help. We have to look for a more suitable way out.
Possible treatments for plants
The subject matter is real even with meticulous care, and therefore safe fighting options are required. Gardeners are offered to treat gooseberry powdery mildew with chemical agents, agricultural equipment and home methods.
Agrotechnology, homemade methods do not give a bad result, if the possibilities allow the gardener to often stay on the site, to disinfect the shrubs regularly or the disease is not widely spread.
The treatment of shrubs with alkaline solutions from rotted hay or wood ash is popular. But as evidenced by the reviews, it does not give the desired result and then you have to use chemical agents - biofungicides, fungicides.
They are effective, so you can familiarize yourself with common solutions that strengthen the immune system of the plant and prevent the disease itself.
It takes one hundred grams per ten liters of water. After dissolving the agent, the solution is ready for spraying. They are immediately sprayed with bushes, because it works only for two hours after production, then it is ineffective. Here you can add soap. Ten grams of the drug is diluted in half a liter of heated water, soap (100 grams) is diluted separately, preferably without chlorine. At connection the emulsion with a greenish shade turns out. It processes the shrubs in the spring before the budding of new buds, after flowering or at the beginning of the ovary.
Which is a preventive and curative (therapeutic) drug with high rates against fungal and other diseases of berries, fruits, vegetables, ornamental crops. It is not toxic to insects and is able to suppress the primary infection of the fungus. It is used in the development of culture and fruit ripening. Two grams of the drug is diluted in ten liters of plain water. Cultures are sprayed with this solution immediately and repeatedly in ten days. For gooseberries, it can be used several times a season.
This means it is necessary to moisten the green mass and branches of the shrub. The drug is practical and easy to use. It takes fifty grams, ten liters of water and fifty grams of soap. This prophylactic agent is used once or twice in the spring and summer period. The remains can be poured into the ground under a bush.
As a violator of the fungi life cycle. It has systemic activity, resistance to precipitation, a long period of protection, increased yields.
Not bad proven killing infections - Vitaros, Acrobat MC, Skor, Fundazol, Previkur.
Alkaline solution with ash
It is effective after the gooseberry bloom. A mixture of a kilogram of ash and a bucket of water must be boiled for half an hour. Then cool, for better hitch add soap.
In the second such variant, the ash is not boiled, but simply infused for ten days. After draining, soap is added here. Processing is carried out twice a day in cloudy weather with an interval of seven days. Leaves should be moistened above and below. Residues can be poured into the ground to eliminate hibernating infections,
Отлично предупреждает появление грибка. Его берут один килограмм свежего или сто грамм сушеного на десять литров воды. Сутки настоять и один-два часа проварить, потом остудить, отцедить. Рабочий раствор для опрыскивания готовится в соотношении один к пяти. Таким отваром пользуются весь сезон с перерывами в семь дней. It can be stored for a week
Tansy (three hundred grams fresh or thirty grams dry)
It is filled with ten liters of warm water. Let the mixture stand for a day, then boil, cool, filter. Such liquid can be used immediately without dilution. Processing of fruits, all green mass, and the soil around the bush can be carried out in spring and autumn,
You can also apply. His two drops are added to the whey. This solution can both heal and increase the resistance of the plant to ailments,
Everyone has a first-aid kit. Two tablets dissolve in six hundred milliliters of water, the solution is ready for use,
It has high antiseptic properties. It is used in proportion - two drops are dissolved in one liter of water Fresh cattle manure is a good biological tool. The solution consists of a third manure bucket, filled with water to the edges of the tank. After three days of infusion, it is filtered. The proportions of the working solution - one to ten,
In the application of all gooseberry treatment options, you should follow the general recommendation - a month before picking berries, all spraying stops.
Plant disease prevention
The most ideal remedy for disease is prevention. Its purpose is to prevent the ingress of fungus disputes on plants, the soil and their further development. Therefore, as soon as the summer season begins, it is necessary to engage in the prevention of the entire site.
It should follow the useful recommendations of experienced gardeners, gardeners:
- At the time of purchase, carefully consider cuttings. They must be healthy, strong, adapted to the conditions of certain regions. Should not be lethargic, stained, other damage, or generally causing doubt. It is worth finding out what varieties are offered. Susceptible to fungus - Prune, Russian, Triumphal, Date, Lefora, Seedling,
- Since powdery mildew is afraid of heat, the gooseberries should be planted where the sun is constantly, it is necessary to maintain the distance between the bushes (preferably one and a half meters) so that they are well ventilated. The ground near the bushes should be promulcated with sawdust, cardboard or covered with foil,
- As soon as the first leaves appear, the bushes are poured with hot water (not higher than ninety degrees) with the help of a watering can, with the possible addition of soda or manganese,
- Last year's fallen leaves on the bite area should be removed, there may be overwintered fungal spores on it,
- It should be cut dry, not fruiting branches, you should not allow thickening, you need to build a special rounded grid that supports the branches of the plant,
- Infected shoots, in the fall, in the spring, are removed far away from the site and burned, the ground near the bush is dug up, the spores remaining in the ground or in the fallen leaves must go down into the ground by no less than fifteen centimeters,
- It is not safe to inspect healthy specimens after examining infected bushes and caring for them; the disease can be transmitted through hands and watering,
- A good prevention are the stems of the nightshade - potatoes, tomatoes. This litter should be watered with either preparations or fertilizers containing microorganisms useful for asthenia. After exposure to bacteria, they are able to eat disease spores, decompose mulch, improve the soil,
- In no case do not apply nitrogenous fertilizers. For gooseberries, potassium chloride, potassium sulfate, that is, potash fertilizers, which improve immunity, sugar content and color saturation of fruits, are considered ideal
- You can plant garlic, parsley, mint between the bushes.
It is advisable to purchase gooseberry resistant to fungal diseases. According to gardeners, the most resistant non-prickly varieties: Chernomor, Captain, African, Northern, English yellow, Eaglet, etc.
The sphere is a widespread disease of shrubs. Than to process a gooseberry from mealy dew, each gardener decides for himself - either with purchased or home remedies. Not least, and prevention, it also leaves no chance of disease, but if there is no proper care, you will have to say goodbye not only to the harvest, but also to the plant itself.
Mealy dew is the gooseberry's worst enemy
Even the thorns on the bushes do not prevent pests from settling on the plants and eating them. Most of all, gooseberry and currant are affected by fire-earing and sprouting. But the most dangerous are spore fungal diseases. One of them is a scab, or a sphere library, which summer residents call even powdery mildew (it is very similar to cereal powder).
Once this problem was brought to Europe from America along with berry seedlings, and powdery mildew almost ruined the gooseberry plantation.
On a note. Under the influence of the sphere library, young shoots begin to grow crookedly, the leaves curl into a tube. Multiplying, spores cause rotting of the tissues on the plant and subsequent drying of the bush.
Affected leaves no longer participate in photosynthesis, causing the respiration of the whole plant to be disturbed. This affects the development of berries - they are badly poured and lose their taste. If the mycelium reaches the fruit, the gardener will be left without a crop - the affected gooseberries are no longer suitable for food.
What is a sphere library
When powdery mildew appears on the gooseberry, control measures are taken immediately, because the disease spreads over the area at high speed. Disputes from bush to bush are transferred by means of wind, insects or with splashes of water during irrigation (rain).
The raid, which can be seen on all parts of the gooseberry, really looks like a flour of a grayish-white shade. This is the mycelium, on the surface of which, by the end of the growing season, the celestocarpia will appear - fruit bodies. Outwardly, they look like microscopic felted balls of dark brown color and contain spore bags inside. In this form, the sphere library winters and continues to infect plants in spring.
For the progressive stage of the disease is characterized by a brown film, enveloping shoots and berries. If a large part of the leaf plate has darkened, we can talk about the final phase of the defeat by dew.
Phase of the disease spheroid
The main causes of infection - agrotechnical: The greatest activity of fungal spores occurs with the onset of spring and summer. Favorable conditions for reproduction of the sphere library are increased humidity and heat. If the plant managed to pick up the fungus last season, then in the current one it will hurt in dry weather.
- there is a high occurrence of groundwater,
- for the berries chosen lowland area,
- seedlings with weak immunity were used,
- the planting pattern was not followed, making the berry thickened,
- a surplus of nitrogenous fertilizers.
To stop the spread of infection, gooseberry processing from powdery mildew is carried out in the spring before budding, during flowering, in the summer and autumn before the most frosts. At the same time, the bushes need not just be sprayed, but also plentifully poured gooseberries, capturing every particle of the plant, not forgetting to thoroughly cultivate the land around, as well as neighboring crops.
You need to combat powdery mildew in a complex way, using chemicals, folk remedies, and also following the basic rules of agricultural technology.
Means of prevention and control
Spraying gooseberries as a preventive action is mandatory. But even in time, the protection measures taken do not always work, and the plants can get sick. Therefore, the bushes need to be processed at the first signs of a lesion, using reliable fungicides. Pick them up, given the period in which the disease occurred.
List of Recommended Chemicals for Powdery Mildew
Interesting. Most gardeners prefer Bordeaux liquid as a universal remedy for various misfortunes. The chemical industry also produces analogues of this drug: Phthalan, Copper Oxide, Oxyh. Iron sulfate, colloidal sulfur, fast, and phyton also give good results.
The last two means in the table are biological products that do not affect the quality of the fruit. Therefore, they are boldly used in the middle of summer, when a lot of berries have started to tie on the branches. Chemical fungicides are a spring control method, but they can be used in early summer (June), as well as some of the protective measures should be moved to autumn.
Mealy dew: what it is, how the disease affects the yield of berries
Determine the infection of the bush is simple. On the berries, a cobwebby friable white bloom is formed, which eventually develops into dense brown spots. Gradually, the fungus passes from the berries to shoots, bending them, and then to the leaves, which makes them turn yellow and curl.
Berries begin to crack and crumble, even before ripening. If you do not take appropriate measures in time, the powdery mildew of the gooseberry will amaze and spoil the whole crop, and over time will destroy the whole plant.
How to get rid of powdery mildew, country ways
It is necessary to fight the scourge immediately after detection. If the berries have already appeared, they are ruthlessly destroyed along with the affected shoots. If, however, it was possible to detect the disease before the buds were dissolved, it is necessary to take appropriate measures immediately.
How to beat powdery mildew? We offer several proven folk methods.
To fight using different types of nitrate, but about the same proportion. So, for the treatment of bushes after flowering do ammonium nitrate solution: on a bucket of water take 50 g of funds. Also used potassium nitratetogether with potassium permanganate in a ratio of 50 g and 3 g per bucket of water.
Aspirin and soda
When white raids appear on the gooseberry bushes for spraying, they prepare a solution of soda with the addition of aspirin and soap. The last is necessary in order that means well adhered to a bush, lingering on it.
About 50–60 g of soda and about 10 g of liquid or grated laundry soap are taken to a bucket of water.. It is important that the solution is thick enough. It is necessary to spray every week two or three times.
How to remove white bloom on gooseberry with ash
Among the safest folk remedies for powdery mildew is considered wood ash solution. To prepare it, you need to take a kilogram of ash, clean it and sift. Then heat the bucket of water and dissolve the purified ash in it.
He must insist about a week, occasionally stirring. And on the last day they do not touch him, giving him the opportunity to settle well.
Then it must be filtered, add household soap and use as intended. Processing bushes should be carried out in calm weather in the evening. Leave a little solution, add water to it and pour the bush.
Use kefir or sour milk
Surprisingly, but the struggle with powdery mildew folk remedies has in the stock such means as fermented milk products - sour milk and kefir.
The fact that their texture helps to create a kind of film on the plant, which interferes with the breathing of mycelium. At the same time, the gooseberry itself receives beneficial substances and improves its health.
To prepare the solution using lactic acid products and water in the ratio of 1:10. In this case, the bushes are treated only in dry weather. This must be done three times in three days.
The use of drugs in the treatment of powdery mildew on the gooseberry
There are many traditional methods of fighting fungus. On the market there are a number of chemicals that really quickly and effectively fight the disease.
But some gardeners prefer a less reliable, but more bacterial treatment method that is safer for the plant and man. Let's consider each of them so that every gardener who has a sick gooseberry can decide for himself how to spray the plant.
Use of chemicals (fungicides)
The current fungicidal agents can effectively deal with powdery mildew. They penetrate the plant cells, treat it, protect and inhibit the development of the fungus.
Depending on how you decide to fight the disease, the bushes should be processed one to four times with a break of about 7–10 days.
The most popular mealy dew products are:
- Amistar Extra,
- Acrobat MC,
Biofungicides: how to cure gooseberries with biological preparations
In the fight against white plague also use fungicides of biological origin.
First of all, it is fresh manure cattle. To prepare the solution is taken one-third of a bucket of manure, which is filled with water to a full bucket.
The mixture is infused for three days, then filtered and diluted with water in a ratio of 1:10. Dilute the infusion each time before processing.
In the fight against powdery mildew, weeds from the garden are also suitable, which are used in the preparation of fermented grass.It is necessary to chop half a bucket of weeds finely, pour them with hot water to the very top of the container and mix. The mixture is also infused for several days, filtered and used undiluted.
Actions to prevent
Prevention consists, first of all, in the correct care of a bush. So, you need to make sure that the planting does not thicken, has moderate moisture, and the soil is sufficiently fertilized with organic matter.
Be sure to cut off the old branches and those that bear bad fruit. It is also recommended to fold the tops of tomatoes and potatoes under a bush, watering it with a solution of EM preparations.
The plant will slowly decompose under the action of bacteria, which will absorb the spores of the fungus.
But after leaf fall, the leaves must be removed from the site and burned. Be sure to dig in the fall and spring area.
Another means of prevention - landing powdery mildew-resistant gooseberry varieties. These are Chernomor, Captain, Northern, English Yellow, Consul, Eaglet and others.
For the planting of any variety, it is necessary to choose exceptionally healthy and strong plants that are adapted to the given region.
Mealy dew is a dangerous disease that can destroy not only the harvest, but also the entire shrub planting. Therefore, it is important to immediately begin to fight the fungus at the first sign of its appearance.
It is possible to fight with it both national methods, and special preparations. The latter are very effective, but the former are safer. In order not to bring the matter to treatment, it is better to carry out preventive measures in advance for gooseberry bushes.
The mealy dew on the gooseberry leads to dire consequences, but this is only if you do not start a fight with it. In fact, the treatment of affected plants is quite simple. You can resort to the help of folk and chemical means.
Recommendation! These two methods of struggle will give a positive result much faster if you apply them together!
If you are an ardent opponent of the use of chemicals in your area, then you can resort to using only popular recipes, of which there are quite a lot. But if the disease is in a neglected state, then it is simply impossible to do without chemicals. In addition, chemicals can be enough to carry out just one treatment, while folk preparations will need to be applied 2-4 times. And with a high temperature of air and humidity, it will be quite problematic to defeat the disease with such means.
- The most popular remedy for powdery mildew on gooseberries is copper sulfate solution. It is prepared as follows: 75 g of finely chopped laundry soap is dissolved in 5 l of water at room temperature, 20 g of copper sulphate is introduced into a soap solution in a thin stream. The finished emulsion should have a slightly bluish tint and a smooth, flaky, consistency. The finished product is treated bushes before the beginning of the flowering period. If for any reason this phase has been missed, then, in extreme cases, the culture can be sprayed after the ovaries of the fruit appear on the bushes.
- Another chemical that shows high efficiency in the fight against powdery mildew is called Topaz. It must be diluted to a certain concentration, as written in the instructions, and used to spray the bushes after they bloom.
Tip! If the disease is started, then it is advisable to carry out the treatment twice - not only after flowering, but also before it. However, as evidenced by reviews of gardeners who had time to try Topaz in action, in most cases only one spray is enough!
- For the first tool you will need a tablespoon of soda, 75 g of soap and 15 liters of water. First you need to prepare a solution of soap and water, then add soda. The finished tool is poured over the root zone of the plant, as well as the leaves with a watering can with a nozzle-strainer. Процедуру проводят один либо два раза с промежутком в 7-8 дней.
- 1,5 кг золы растворить в 5 л горячей воды и оставить на 24 часа. Настой профильтровать и использовать для опрыскивания культур. Обработку провести дважды – до цветения и после. Spray plants after flowering, if necessary, can be 2 times. The interval between procedures should be 7-9 days.
- 200 g of urine diluted in 5 liters of water. The resulting agent is sprayed immediately after flowering. The treatment can be repeated 3-4 times at the usual weekly intervals.
- In the early stages of the disease, spraying with a solution of potassium permanganate is recommended. To prepare a bucket of water, add no more than 1.5 g of potassium permanganate and mix.
- 1 part of fresh mullein is diluted with 3 parts of pure water and left for 4 days. The resulting solution is diluted again in the same way (1: 3) and used for spraying the plants. The treatment should be thorough, and for irrigation it is advisable to use a regular broom, with which you will be able to apply the drug as much as possible to the leaves.
Mealy dew is not a rare problem. And if you don’t want to get involved with it, then you should plant varieties resistant to it on your plot. These include:
On a note! Leaves of a gooseberry without thorns are subject to the most powdery mildew!
But there is such a gooseberry, which has a high predisposition to this disease:
How to prevent the development of the disease?
And of course, we must not forget about prevention.
- It is imperative to carry out autumn or spring pruning of the bushes, and to remove infected shoots and burn outside the site.
- Examine the bushes in spring and summer for the presence of infected shoots and leaves and if they are found, remove them immediately.
- Before winter and in 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 period of swelling of the kidneys, pour boiling water over the bushes - this is an excellent prevention of not only powdery mildew, but also other fungal diseases.
- It is desirable to fertilize the crop with potash and phosphate fertilizers and try to refrain from using nitrogen supplements, as the former increase the resistance to powdery mildew, and the latter often do not allow the shoots to mature fully, which leads to a strong defeat of this disease.
Preventive measures are desirable to combine and apply comprehensively. Have a good harvest!
Mealy dew on gooseberry - prevention and measures to combat it and other diseases
Plant a mildew resistant variety .. now there are such.
Damp, do not ventilate the bushes. "Topaz" from mealy.
If the disease in the garden is highly developed, one of the following preparations of the gooseberry are prophylactically sprayed in the autumn before the leaf fall and in the spring before the budding of the buds.
Possible, and it is extremely effective if on time. If not, it will be necessary to more thoroughly prepare for spraying, to produce it more often, if not at all, to carry out the processing by chemical means.
The solution of mullein specially prepared and infused for 3-4 days will also help to cope with the disease. It is only necessary to take a fresh mullein and dilute it with clean water, 1: 3, then insist and dilute again, also, 1: 3. To spray the plants is not very abundant, but carefully, preferably with a simple broom, every week.
Try to keep the site as clean as possible from weeds, in time to remove the shoots, mowed plants, to prevent contamination and thickening,
Recognizing a serious disease of a cultivated plant is very simple, you just need to pay attention in time to the bush and berries.
The solution of copper sulfate, which is obtained from a bucket of water and 80 g of substance, has proven itself well in eradicating the disease. The same effect is exerted by the nitrafene solution, which is prepared from 200 g of the substance and 10 liters of warm water. Any of these agents is sprayed onto the gooseberries before the buds bud on the branches.
Compulsory cleaning of leaves and fruits fallen after the disease, which must also be immediately destroyed (especially if powdery mildew is diagnosed),
The prevention of powdery mildew is similar to the work on the prevention of anthracnose - spring digging and spraying. When processing young shoots, good results are given by the preparation prepared as follows: 3-liter container is filled with charcoal and ash, topped up with water, brought to a boil and “boiled” for about half an hour. In the resulting solution, add about 40-50 g of chopped soap, stir, cool and use for spraying. And of the ready and safest fungicides that treat powdery mildew and other fungal infections, Fitosporin is considered.
One of the dangerous fungal infections. Their first signs can be seen on the green parts of the gooseberry - foliage, young shoots and even on the stalk. At first, these are just separate brown specks that grow and grow, spreading the infection. Leaves fall on the diseased plant, it stops its development and no longer wait for their berries.
Glass rust and columnar rust
Chemistry sorted out. I know a person so he still when the snow did not come down and the buds did not move, did so. Boil the bucket in the watering can and watered the bush. I thought I would cook everything. No, everything grows well and does not get sick.
The simplest is to cut and burn!
Septoriosis (white spot)
However, I believe that in the garden it is better to have gooseberry varieties resistant to powdery mildew, like: African, Russian yellow, Jubilee, Finnish and. others
Hello, Khalilov Frans Khasanovich! How to deal with powdery mildew on gooseberries?
Solutions of mullein and potassium permanganate to combat powdery mildew on gooseberry
- Choose for planting only healthy and strong plants, necessarily adapted to the planting region,
- Fruits are covered with white bloom or light white-yellow film, which dries and turns into thicker formations that affect the entire surface. Mealy dew can pass on the leaves, but more often it is found on currant bushes.
- The leaves are sprayed with a 3% solution of Bordeaux liquid. It is obtained by thoroughly mixing 10 liters of water, 300 g of quicklime and 300 g of copper sulfate.
- Avoid stagnation of moisture under the bush (landing on a hill, a drainage device, improvement of clay soils by making sand and peat)
Mealy dew on gooseberry - control measures
It is found in many popular berry crops - strawberries, strawberries, but sometimes it also affects gooseberries. Although gray mold is not considered as dangerous as the diseases mentioned above, the damage from it is palpable. It is not difficult to determine the signs of infection - gray bloom on fruits and their inevitable loss. The berries on the affected plants rot and crumble.
Powdery mildew control methods
Like all fungal diseases, anthracnose spores are activated in wet weather conditions that occur after a long rainy period or cold fogs. If the plots are located in lowlands or the soil on them is heavy, with frequent stagnation of water, the probability of outbreaks of the disease is high.
It is desirable to replace the variety. we do not have gooseberries at all. What about boiling water works if your neighbors are approximate and there are no diseased plants. as well as the wind all the infection spreads around. We had a conversation with Angran on this topic. Spray constantly is money to spend on poisons and harmful procedure for the person himself.
Powdery mildew control with folk remedies
I changed the grade planted "pear"
This is a fungal disease and it appears after flowering on young shoots and ovaries in the form of a white powdery plaque, which gradually thickens and becomes like a brownish felt. The shoots, damaged by powdery mildew, are severely bent and dry, the berries are showered, and the rest lose their presentation.
Unzirka, perhaps from diseases, the greatest harm to the gooseberry brings
Powdery mildew on gooseberry - chemical methods
Spraying wood ash solution is considered very effective, and most importantly, safe for plants and humans.
To prune and form plants, remove distant branches and plants from the garden or even the entire dacha, burn them outside the territory,
The fruits of the gooseberry under the influence of a dangerous disease change and in shape, become smaller, develop poorly and dry, and the leaves curl, dry and lead the plant to death. When the gooseberry blooms, you can apply a solution of soda ash.
Annual rejuvenating pruning, contributing to better lighting and ventilation of the bushes.
Signs of powdery mildew on gooseberry
Spores of the fungus overwinter on damaged shoots and leaves, and in the spring they are spread by wind and insects. Getting on a healthy plant, they quickly germinate, hitting the plant. Wet and warm weather is especially favorable for the development of powdery mildew. If gooseberry bushes are located on an elevated open area, the degree of powdery mildew damage decreases.
For the preparation of powdery mildew it is necessary to perform a whole ritual, but it is quite simple. Immediately 1 kg of pure and, what is desirable, sifted ash is dissolved in a bucket of heated water. The resulting solution is stirred once a day and insisted for 4-7 days.
Try to clean the site after leaf fall, clean the soil (cultural mulching and warming are not considered here).
Due to the rapid development of the disease, it should be fought very actively, otherwise lesions can spread not only to one bush and spoil its crop, but also spread to nearby plants, which will deprive you of the entire crop.
It is taken in a volume of 50 g and dissolved in 10 liters of water. For better effect, a small amount of soap dust can be added to the solution. A good solution has a weak solution of potassium permanganate, which is prepared from a bucket of water (10 liters) and 1.5 g of the substance. Such spraying must be repeated after 7-10 days.
How to protect plants from powdery mildew?
One of the most dangerous diseases of gooseberry is powdery mildew. This fungal virus that affects almost all parts of the shrub (leaves, shoots, branches and berries), appears gray-white bloom, which eventually darkens to a brown-gray shade. Most importantly, with the arrival of winter, the fungus does not die, but carries on the affected parts of plants. In the spring, he throws spores, and neighboring shrubs become infected. That is why many gardeners want to know about the measures to combat the American powdery mildew of gooseberry, which is so called due to the fact that the disease has come to Eurasia from America.
It can be diagnosed by noticing the appearance of yellowish tubercles on the underside of the leaves, as well as on the buds, flowers and ovaries. Over time, they turn into a kind of "felt" plaque, the plant weakens, the quality and quantity of the crop falls. The cause of the appearance of Goop rust is considered to be the unfavorable neighborhood of gooseberry with sedge or cedar plantings. From this we can conclude that the effective prevention will be timely cutting of sedge, or in the case of cedars, the transfer of a bush to a new place. Infection with columnar rust can occur if the area is located next to a pine-tree, on the basis of which measures to prevent the disease become apparent.
The first procedure must be carried out before bud break, and given that the gooseberry is very early in this regard, it is important not to miss the moment!
- Thaw the bushes so that each branch is blown by the wind (about 10 cm between the twigs). Dilute in the bucket hoz. Soap 100 g and add to the bucket 1 liter of sifted wood ash. Stir well and leave overnight. In the morning a broom to handle all the bushes. Do this:
- Most importantly, plant varieties resistant to the sphere library (powdery mildew). If you need to save this particular grade, then only chemistry. All folk remedies, alas, do not help. About nitrofen, what they wrote to you is effective, but it has long been discontinued and banned for use. Of the more benign and non-chemist Fitosporin. This is a biological product. But they need to handle almost every 2 weeks. In the early spring, still in the snow, before the swelling of the kidneys I spray copper sulphate or Bordeaux mixture, it is possible with Topaz. Then, when the kidneys are cracked, again. After flowering for the prevention of already the same phytosporin. In the fall of the fall foliage again Topaz. Foliage must be collected and burned. Yes, this is chemistry, but at least I control when and how much. But gradually I turn to varieties that are matched to the spherotereka. Correctly they wrote that the varieties are more strongly affected if they are bleached or in the shade. But one variety I was even very sick at the most "trump" place, until I began to heal
- Powdery mildew is as follows:
- . The disease manifests itself in the form of white bloom (flour) on young shoots and leaves. Then, in the second half of the summer, it passes over to the fruits and covers them in the form of a thin felt layer. Berries do not increase in size, become unsuitable for consumption. Shoots bend, stop growing, leaves curl. The spread of the disease contribute to thickened planting and wet weather.
Copper sulfate from powdery mildew
Far from the fact that preventive measures will help to fully resolve the issue. And it may just happen that the disease will come from the other side of the garden, which you didn’t treat, or even from neighbors, who don’t even take care of the garden. In general, the problem is real even with the closest attention, and therefore we need safe methods of dealing with it.
Gooseberry treatment with soap and soda
Time to recognize the disease will help signs of powdery mildew
To destroy the powdery mildew on the gooseberry, you can use fungicides (that is, chemicals that are used to combat fungal diseases), which are sold in specialized stores. These are, for example, “HOM”, “Abiga-Pik”, “Tiovit Jet”, “Vectra”, “Kulumus”, “Skor”. They are diluted in water according to the attached instructions, most often about 25-40 g per bucket of water.
A solution of potassium permanganate from powdery mildew
The main method of dealing with this dangerous gooseberry disease is spraying. A solution is prepared, which then needs to be sprayed onto the shrub and the soil beneath it using a sprayer with a spray nozzle. The solution is treated, as a rule, first the upper part of the bush. Then the lateral and lower parts of the shrub are sprayed: try to get on all the shoots and leaves from all sides, and, of course, cultivate the land around the bush. The first spraying is carried out in early spring, before the active growing season, that is, before bud break. The second procedure is carried out at the beginning of flowering, and the third - in 7-10 days. Spraying, by the way, is carried out in calm, calm weather.
Processing gooseberry solution mullein
In addition to radical transplant measures, treatment and prevention may include traditional spring digging of soil around the plant and spraying them with antifungal drugs (Fitosporin, Bordeaux mixture, and others).
Opponents of the use of "chemistry" can replace drugs with organic solutions: one third of a bucket of fresh manure, mullein or bird droppings is poured with water and allowed to brew for 2-3 days. After this infusion filter, diluted with water three times and used for spraying.
Treatment of gooseberry ash solution
= Before bud break,
Earlier was the drug Colloidal sulfur Now Tiovit Jett instead
1. To destroy the wintering stages of the fungus, in the fall or early spring, cut the affected shoots, remove the fallen leaves and berries, and dig up the soil under the shrub.
In recent years, amateur gardeners have found a very effective and environmentally safe method for protecting currants and gooseberries from powdery mildew: spraying the bushes in early spring with boiling water. This is how I spray. Early in the spring, as soon as the snow melted, the currant buds had not yet begun to swell, heating the water to a boil and immediately pouring it into the watering can and pouring the bushes evenly and carefully over this boiling water. On a large fruiting shrubs spend a full watering boiling water. The bush should be sprayed very carefully, so that drops of boiling water wetted each branch from top to bottom.
Spraying should be carried out in the evening, in calm weather, carefully processing all the leaves and shoots. The remaining mixture can be supplemented with water and water the plants to kill all unnecessary and in the soil.
A solution of copper sulphate, namely a mixture of 80 g per bucket of water, is recommended to be used for treating plants and soil in early spring, even before bud break. It is desirable to carry out the processing of the sprayer, very carefully.
Proper care for gooseberries (video)
Mealy dew can attack gooseberries from other plants, for example, from currants, strawberries and others, but it often happens that the causative agent of the disease just hibernates in the soil and moves to plants during a favorable period.Gooseberry powdery mildew is indeed a serious problem.
How to get rid of powdery mildew on gooseberry?
Which should be approached with caution. It is not always convenient to poison the plants with chemicals, since the fruits are sown quite quickly, and other methods do not always help. So what to use summer residents in the fight against powdery mildew of gooseberry?
Говоря о борьбе с мучнистой росой, в первую очередь следует упомянуть народные средства. Хороший результат можно ожидать после обработки крыжовника зольным раствором. Его готовят из ведра теплой воды и 1 кг древесной золы, настаивают 4-6 дней, а затем используют трижды, каждые 2 дня.
The effective protection for the gooseberry is the same as in the case of powdery mildew - the treatment of the bush before bud break with a solution of blue vitriol or the drug NITROPHEN. After a while, spraying can be repeated using Bordeaux mixture at a concentration of: 100 g per 8-10 l of water.
Another name for this gooseberry disease is American powdery mildew. Signs of infection are whitish bloom that appears after a period of flowering. Later spots of gray become more dense and become brownish. Owing to the disease, the plant slows down all development processes, their shoots weaken and deform, the leaves dry up, and the formed ovaries fall.
= When young shoots grow to 10 cm.
Pour boiling water from the kettle
3 Immediately after the gooseberry blooms, it should be sprinkled with a solution of soda ash (50 grams of soda, 50 grams of soap per 10 liters of water) or a solution of ammonium nitrate (50 grams per 10 liters of water) or infusion of mullein (1 part of rotted manure and 3 parts of water insist for three days, then diluted with 3 parts of water and filtered).
I repeat the second important feature: at the time of spraying the currant buds should not be swollen and open. For ease of spraying and increasing the effect before the procedure, the bush should be collected and tied up with a string, so that it has a diameter of 60-80 cm. If the bushes are not yet released after the autumn binding, then, on the contrary, they are somewhat free. Spring spraying of the bush and the soil under it with boiling water naturally kills the beginnings and other diseases, as well as the pests eggs laid on the surface of the branches.
Any treatment is recommended beforehand, even before the plant starts to hurt!
Copper sulfate, soda ash and soap from powdery mildew in the garden
Is it possible to protect gooseberry from powdery mildew? What preventive measures to use?
Today, DachaDecor.ru specialists are ready to solve issues with diseases and pests of plants on a turnkey basis, and therefore we very much hope that our efforts will help each of our readers.
Among the means to combat powdery mildew, infusion of mullein is popular. It is produced from 1 part of a mullein, diluted in 3 parts of water, then infused for 3 days. After this infusion is decanted and used for spraying.
General rules for dealing with any fungal diseases necessarily include:
The most effective prevention of powdery mildew is the cultivation of certain varieties that are fairly resistant to fungal infections. Among gardeners and gardeners, the cultures of our breeding are well-deserved: Spring, Russian, Lada, Pink 2, and others, and from overseas, Pearl, Jocelyn, Houghton. It is possible to improve the plant immunity by planting it in sunny, well-ventilated areas, as well as fertilizing with phosphorus and potassium.
And do not overfeed with fresh manure and nitrogen fertilizers.
On a liter of water TEA spoon of baking soda, gooseberries and currants sprinkle.
4 When buying seedlings, give preference only to ultra-resistant gooseberry varieties, and then powdery mildew will not dare to approach them.
A further fight against powdery mildew continues before the gooseberry blooms and then after flowering. The gooseberry responds more painfully to copper medications than other crops. Therefore, the use of Bordeaux fluid, iron sulfate is not desirable. At this time, gooseberry against powdery mildew can be sprayed with folk remedies. For example, a suspension of kefir in water. For this treatment, 1 liter of kefir is diluted in ten liters of water. Sprayed twice: before and after flowering. At the same time (before and after flowering) you can spray it with other means: infusion of mullein, infusion of 1 bucket of mullein in ten buckets of water. Spraying gooseberry with lye (infusion of ash) at the same time as an effective measure to combat powdery mildew and good phosphorus - potassium foliar top dressing. Go
To combat powdery mildew on gooseberry bushes
Mealy dew is a serious gooseberry disease that can take away your harvest.
A good result gives and the processing of the gooseberry soap and soda solution. It is prepared to a homogeneous liquid from 50 g of soap, which should be rubbed on a coarse grater, 2 tablespoons of soda and a bucket of water. The solution is then used before and after flowering.
Cutting infected branches, followed by burning,
On the other hand, excessive spring pruning and frequent application of nitrogen fertilizers can lead to the fact that plant protection will weaken and it will be difficult to resist the disease.
Prevention and treatment.
Signs and features
Gooseberry bushes can be infected by disease spores using insects or wind. In addition, the disease can affect the bushes of raspberry, currant and some other shrubs.
The disease foci can be detected in a visual way: a characteristic white bloom appears on infected leaves. It looks like flour scattered on leaves.. However, the disease affects not only the leaves of the plants, but also the shoots themselves, and therefore it is worthwhile to study in more detail how to get rid of the powdery mildew on the gooseberry. After all, if appropriate efforts are not made in time, the disease will first destroy the fruit, and then the plant itself.
The peak of the disease occurs at the end of spring. Indeed, in May, young shoots begin to form on the shrubs and fruit are tied. In addition, warm weather and humidity contribute to the rapid proliferation of spores.
Initially, the characteristic symptoms appear on the lower branches of the gooseberry. It is there that infectious disputes can persist since last summer. Summer residents with experience immediately understand the danger and destroy such branches. If this is not done, then the light patina becomes brown with time, and the disease enters a new stage, which ends with the death of the fruit.
The remaining berries have an ugly peel and are practically unsuitable for human consumption.
In addition, the affected leaves twist first, and then completely fall off. The same happens with the ovaries. On the already available fruits small cracks appear and after a while they begin to crumble from the bush.
Methods of dealing with the disease
With the right approach, you can win such terrible diseases affecting fruit bushes, like fungal spores. First of all, you should learn how to deal with powdery mildew on the gooseberry and destroy this disease. There are several methods to combat this infection. Let us consider in more detail each of them:
Used in the primary lesion of fruit bushes. It is based on the selection and planting of resistant plant varieties and pruning of branches that show signs of infection. The operation is carried out in early autumn or spring. These varieties include: Kolobok, Ural grape, Jubilee and some others. Cut the branches should be burned or carried out of the site. For prevention in early spring, the shrub is cleared from last year's foliage and dried branches. It is there that disease spores can hide.
Besides, as all damaged leaves are found and the branches are removed. After the snow melts, before the buds swell, the gooseberry bushes should be treated with hot water and potassium permanganate. This will destroy the pathogenic bacteria on the plant itself, and in the soil near the bush.
At each bush will need a bucket of water, where two large spoons of potassium permanganate are dissolved.
In order for gooseberries to have strong shoots, it is necessary to feed its bushes with potash and phosphate fertilizers. It is not recommended to use nitrogen fertilizers, which are bad for the growth of young shoots and, therefore, weaken the protection of the shrub from various diseases.
It is used to infect all gooseberry bushes in the area. Spraying of chemicals is carried out before flowering and after picking the fruit.
To do this, use the following drugs:
- Copper sulfate.
- HOM and some others.
The method is combined. It combines both methods described above.
All these methods need to be known in order to imagine how to deal with a disease such as powdery mildew on gooseberries. Measures to combat it are quite effective.. But sometimes gardeners give preference to folk recipes, which, as practice shows, are no less effective than scientific ones.
Among them are measures such as:
- Spraying gooseberry with a special solution of a mixture of soda ash and laundry soap, previously crushed. On a bucket of water you need to take fifty grams of each ingredient.
- Treatment with ash solution. On the bucket of water will need three kilograms of the substance.
- You can use any dairy products or even whey. Liter of product is diluted in nine liters of water. Processing is carried out in three stages with an interval of three days.
- The method, which is known even to inexperienced gardeners, is to treat gooseberry bushes with boiling water. This is done in early spring, when the buds are still not swollen.
If necessary, it is necessary to process and spray plants several times. This method will help get rid of the dispute in advance.
To prevent disease, it is necessary to carry out some preventive measures.
- In autumn, all the old branches are cut off, and the soil under the bush is covered with tops of solanaceous crops. The plant decomposes, and the secreted bacteria absorb disease-causing spores. But in the winter of rotted layer should be eliminated. It is removed and burned off-site. In addition, it is necessary to periodically loosen the soil on the site.
- When choosing material for planting, make sure the bushes are healthy and have no damage. It is best to acquire plants that are initially adapted to the climate of your region and have good protection against most diseases.
- For prevention, you can use the drug Fitosporin. It is made by protective bacteria and is considered the most effective way to protect shrubs from various diseases. But unfortunately, the drug can not be used for the direct treatment of an existing infection. Therefore, choosing what to treat gooseberry from powdery mildew in the spring, you need to visit a specialty store and choose an effective chemical agent.
In conclusion, we can say that the disease can be a serious problem for gooseberry bushes and to combat it, prophylaxis should be carried out, clearing the area of debris, eliminating the bushes from dry branches and feeding plants. But if you missed the moment of infection, use all methods to save gooseberries from the disease, otherwise your crop and the bushes themselves may die.
If you are an opponent of chemistry, use folk remedies, which are sometimes no less effective than those that can be bought in the store.
Only with close attention to your garden, timely prevention and effective fight against diseases, by processing and spraying, you can get healthy plants and a good harvest of healthy berries.
