What to do about powdery mildew on petunias. Powdery mildew on petunia, how to fight. Causes of powdery mildew

When eating jellied meat for pancreatitis, many patients do not think about the health consequences of such a diet. Most products used in the preparation of jellied meat have a negative effect on the pancreas.

How can it be dangerous?

Jellied meat cannot be classified as a dietary dish. When consumed, the load on the digestive system increases. The fat content of the dish is at least 15%. Purine-rich broth, when digested, increases blood flow to the mucous membranes of the gastrointestinal tract. The spices contained in jellied meat are irritating to the gastrointestinal tract.

Makes it difficult to work digestive system and such a factor as low temperature dishes. Patients with acute and chronic pancreatitis are not recommended to eat cold foods. Its temperature should not be lower than +15°C.

Do's and don'ts for pancreatitis Diet and nutrition.

What can you eat if you have pancreatitis?

In acute form

Despite the abundance of useful substances and microelements, due to the large amount of carbohydrates, fats and extractive ingredients, jelly stimulates the secretion of the pancreas, provoking an increase in the inflammatory process. It is difficult for the enzyme produced by the organ to cope with the breakdown of those entering the gastrointestinal tract nutrients. A lack of lipase leads to overstrain of the gland, spasm and painful symptoms.

In the chronic stage

Eating jellied dishes to patients with chronic pancreatitis can cause an exacerbation of the disease. Inflammation provoked by a high dose of substances harmful to the pancreas will destroy the therapeutic effect achieved during long-term treatment.

Only after achieving stable remission, patients can, after consulting with their doctor, include jellied meat in the diet subject to the following conditions:

• only poultry meat can be used in its preparation;
• minimize the amount of spices in the dish;
• eat jelly in limited portions.

Recipes for preparing dietary jellied meat

A dietary dish for patients with pancreatitis should contain a lot of proteins and a minimum of fats and carbohydrates. Chicken and turkey meat meets these requirements, so jellied meat from it is less harmful to health.

Making this type of aspic is faster and easier than jellied beef or pork.

With Chiken

It is better to prepare a dish from chicken breast, since this part of the carcass is the least fatty. Required:

• 1 chicken breast fillet;
• 1 onion;
• 2 carrots;
• 20 g gelatin;
• salt.

The breast should be washed and placed in a pan. Then 1.2-1.5 liters of filtered water are poured into the container. The broth is simmered over low heat, skimming off the foam from its surface. After the water boils, place the washed carrots and unpeeled onion into the pan and add salt.

After 1.5 hours of cooking, remove the breast from the broth. Carrots and onions can be discarded. If desired, carrots are cut into cubes and used to decorate the dish. The broth is filtered. 200 ml are poured from it, in which gelatin is dissolved. All parts of the broth are combined and mixed. The cooled liquid is poured into the disassembled fillet.

Jellied meat can be decorated with cut in half quail eggs and greens. The dish is placed in the refrigerator for 8-10 hours.

Turkey

Turkey is a more dietary product than chicken. It contains a minimal amount of fat, but when preparing jellied meat for a patient with pancreatitis, it is better to use only skinned, washed turkey breast. To obtain dietary jelly, the meat is boiled twice. The first broth after boiling is drained. The breast is refilled. This broth will become the basis of the jellied meat.

The same ingredients are used in the preparation of the dish as in the chicken aspic.

Causes

Typically, the disease develops under concomitant weather conditions and improper care of plants. The fungus itself lives in the soil. It does not manifest itself in warm and dry weather if the rules for caring for plants are carefully followed. But if conditions are unfavorable, entire fungal colonies develop, which very quickly infect the plant.

• Cool weather and high humidity. If there is also a shortage sunlight, conditions for healthy plant growth become extremely unfavorable.
• High nitrogen content in the soil.
• Frequent planting of plants, therefore, insufficient air circulation between them.
• The watering schedule is not followed. Don't water the plants too often. It is also unacceptable to over-water the plant after a long drought. These actions destroy the plant’s immunity, and, as is known, diseases most often affect weakened plantings.

When you find plants affected by powdery mildew in your area, it is important to remember that one of the ways the disease spreads is by transporting spores through the air.

When caring for plants, it is enough to touch a diseased plant and then touch a healthy one - powdery mildew infection occurs.

How to define a disease?

Powdery mildew appears as a white coating on petunia leaves.(read about what to do if petunia leaves have a coating on them or they become sticky, and why this happens). At the initial stage of the disease, it looks more like someone lightly dusted the leaves with flour or powdered sugar. But once the leaves are affected, the disease quickly spreads to flowers and buds.

Powdery mildew infection progresses very quickly, infected leaves turn yellow and fall off (read more about what to do if petunia leaves turn yellow and why this happens). Even if new leaves manage to grow on the plant, they look twisted and extremely painful. In just two days, the disease can affect an entire planting of petunias. If treatment is delayed, the plant dies.

You can read more about diseases and pests.

How to fight?

How to get rid of the disease? As soon as a white coating is detected on the petunia leaves, it is necessary to immediately begin treatment of the plant:

1. The first step is to cut off the affected areas and burn them to prevent the infection from spreading further.
2. Under the plant, you need to cut off the top layer of soil and replace it with a new one soaked in an antifungal drug.
3. The plant itself is sprayed with fungicide.

Folk remedies are also widely used in the fight against powdery mildew. Before using solutions, diseased parts of the plant are also removed first.

Despite the fact that when infected with powdery mildew, spraying is not recommended, before the widespread use of fungicidal preparations, gardeners successfully fought the disease with the help of spraying:

1. Treatment with copper sulfate. For 5 liters of water, take 5 g of copper sulfate, add 50 g of laundry soap and mix thoroughly. Treat the plant with the resulting solution once a week for a month.
2. Potassium permangantsovka. Dissolve approximately 3 g of manganese in 10 liters of water, treat the plant with this solution 3-4 times every 5 days.
3. Soda Ash. Prepare a soda solution: 5 liters hot water take 2 tablespoons of soda and 1 tablespoon of shaved laundry soap. Spray petunia bushes with a warm solution 3 times every 7 days.
4. Fermented milk whey. Dilute 1 liter of serum in 10 liters of water and spray the plants with this solution.
5. Mustard powder. Dilute 2 tablespoons of mustard powder in 10 liters of boiled water. With the cooled solution, you can water and spray the petunias.

Remember that if the disease has spread widely, then folk remedies cannot save the plant - the use of fungicidal agents is necessary.

They are most active in the fight against powdery mildew and are able to suppress the spread of the disease at the cellular level. Treat petunias in the evening and in calm, dry weather.

What to treat: drugs

• The fungicidal drug is widely known in the fight against powdery mildew. Topaz", its average price is 75 rubles.
• The drug has proven itself well " Score", its approximate price is 25 rubles.
• Popular among gardeners for the treatment of powdery mildew " Fundazol" Available in powder form, the price is about 40 rubles.
• « Vitaros» is another popular fungicidal agent for controlling powdery mildew. Approximate price 50 – 60 rubles.

Preventive measures

The best way to combat powdery mildew is to prevent the disease. Of course, to avoid problems, you can plant varieties of petunias that are resistant to fungal diseases. But if you do not adhere to basic rules in caring for plants, then even plants with genetic immunity will not resist diseases. Therefore, first of all, try to provide the plants with proper care:

1. Water your petunias only after you are sure the soil ball is dry enough, but not too dry. Use warm, settled water to water your plants.
2. Plantings must be periodically thinned, first removing flaccid shoots (what to do if and why this happens?).
3. When feeding petunias, follow the proportions and do not get carried away with nitrogen-based fertilizers.
4. Give preference to potassium-phosphorus mixtures, they promote the development of immunity in petunias.
5. Inspect your petunia plantings daily.
6. Periodically spray the plants with a biofungicide. You can use “Fitosporin” or “Pseudobacterin”.

By following these simple rules, you can give your plants a long life and give yourself the joy of positive results of your labor.

It is better to prevent a disease than to fight it later. Do not forget about the prevention of plant diseases, and then you will not have to use fungicidal preparations on your plots. Following agricultural practices will help, if not completely avoid diseases, then certainly reduce their likelihood by 90%.

Experienced gardeners know that most diseases develop on plants due to insufficient care. Be attentive to your plantings, devote very little time to inspecting the plants daily, and they will thank you with lush flowers, becoming a true decoration of both flower beds and balconies.

The life of any plant begins with seedlings, which are transferred to the ground after it has grown stronger. And already at this stage it is worth taking care of the health of petunia, since seedlings can also be susceptible to diseases and pests. Moreover, most diseases and problems are caused by improper care and gardener mistakes.. Let's take a closer look at the most common errors.

It’s worth starting with poor or late shoots. How to determine this? Typically, the package with seeds indicates the approximate time when seedlings appear. The average period is about five days. But many gardeners who planted petunias do not wait for them to appear even after a week. The problem can be either in the seeds and their improper storage, or in non-compliance with the rules of planting and growing seeds, for example, planting too deep, as a result of which petunia cannot germinate, so it is better to plant it superficially.

It also often happens that the seedlings do not shed the shell, that is, the greenish sprout has already risen, but cannot free itself from the seed skin. This problem can be caused by too dry air - it is very difficult for a young and recently hatched plant to shed the dried hard shell. If you encounter such a problem, humidify the air in the apartment or simply sprinkle the seedlings with water. If the problem remains for several days after moistening, then, most likely, the plants will not be able to be saved - the immunity of such petunias will be very low.

Petunia seedling disease

Another problem with young plants is the thinned stem, which can break when the wind blows. This indicates the presence of a fungal disease such as blackleg. Many fungal diseases live in the soil along with the flower, but if you frequently ventilate the plantings, avoid waterlogging and do not overdo it with nitrogen fertilizers, the fungus will not manifest itself in any way. And if you do not provide the plant with proper care, the fungus will definitely awaken, and at the same time it will not be possible to save the seedlings from the black leg.

If you notice plants with thinned stems, remove them immediately and treat the soil with potassium permanganate to kill fungal spores.

Also, the seedlings may turn yellow, which may indicate the presence of chlorosis, that is, a lack of iron. This usually happens due to too much watering or “poor” soil devoid of vitamins and microelements. If you notice yellow leaves, feed your petunia with iron chelate, which can be purchased at a store that sells seedlings, seeds and gardening tools.

It happens that the seedlings begin to stretch upward strongly, while there are almost no leaves on the seedlings. This usually occurs as a result of lack of light or due to elevated temperature in the room. If this happens, there is no need to despair. Try trimming the tops of the seedlings, deepening the planting to the cotyledons. But remember that it is necessary to lower the temperature in the room and provide the plants with additional lighting. In general, you can fight viral and fungal diseases (black leg, gray and white rot) of young seedlings and adult plants according to one scheme: first, remove all damaged plants, and treat the soil with potassium permanganate.

Now let's look at which pests can attack your petunias, and what methods of control are best used against them. The most famous pest is aphids, the main symptoms of which include deformation of leaves and shoots, and wilting of plants. Aphids can be detected by the appearance of shiny dew on the green part of the petunias. If you notice this pest, be sure to treat your petunias with any of the following medications:

• Aktara;
• Ram;
• Kemifos;
• Arrivo.

Another dangerous pest is the whitefly, the appearance of which leads to wilting and yellowing of the leaves. Whiteflies, which look more like white moths, usually live on the undersides of leaves. One of the control options is trapping using glue traps. But if there are too many whiteflies, petunias should be treated with drugs such as Taran and Aktara.

Pest of adult flowers whitefly

Thrips can also be dangerous, the appearance of which is very easy to determine: silvery streaks and a scattering of dark excrement form on the upper side of the leaves. Moreover, the insects themselves are so small (up to 0.5 mm) that it is impossible to see them. Preparations that can be used to treat petunias affected by whiteflies and aphids will also help in the fight against this pest.

Spider mites can also cause damage. The main symptoms of their appearance are lightened leaves, which over time will begin to become covered with dark spots. If you do not start fighting, a thin web will appear on the petunias, and then the plant will die. To combat this pest, you should use powerful means - Demitan or Apollo, preparing the solution strictly according to the instructions.

Why did we decide to talk about powdery mildew separately? This disease is considered one of the most dangerous, but if you know all the rules and remedies, you can cure yours. Before learning how to combat powdery mildew, you need to know what it looks like and why it appears.

This fungus covers the leaves and other parts of the plant with a white coating that is somewhat similar to simple powdered sugar. If you do not start fighting, the old leaves on the petunias will begin to fall off, and new ones will grow crooked and already diseased. Without treatment, your favorite flowers will simply die, so as soon as you see plaque, immediately begin treatment.

• The weather outside is too humid (for plants grown indoors, weather not important).
• You have used too much nitrogen fertilizer.
• Did not comply correct mode glaze. For example, petunia was watered when the soil was not yet dry or, conversely, the plant was not watered at all for a long time.

Powdery mildew on petunia

And, of course, powdery mildew can creep from diseased plants to healthy ones, so try not to plant flowers too close to each other, which will also ensure normal ventilation. To get rid of powdery mildew, you need to use A complex approach in treatment. First of all, remember about proper care:

• Water petunia only when the soil in the pot or flowerbed has dried out.
• Try not to spray weak plants.
• The infected flower must be placed in the sun until it is completely cured.
• If you are sick, stop using nitrogen fertilizers.

Next, you should cut off all the affected areas of the petunia, not forgetting about the flower stalks - the more affected areas you remove, the faster the flower will recover. Due to the fact that mushroom spores are dissolved in top layer soil, it needs to be removed. Do not forget to treat petunias with fungicides, also wash the pots and disinfect them with a solution of potassium permanganate.

The methods listed above are very effective, but they can only stop the development of powdery mildew. To completely cure petunia, it is worth resorting to folk and chemical methods of control. Let's first study the most popular recipes folk remedies against powdery mildew:

• Mix 20 g of soda ash with a few drops liquid soap, dissolve the mixture in 5 liters of water. Stir the liquid well and spray the flowers.
• Garlic will also help you: grate 30 g of garlic, fill it with 5 liters of water. The resulting mixture must be infused for 24 hours, after which it is filtered through gauze - and that’s it, it’s ready for use.
• Mustard powder saves you from powdery mildew - mix 2 tablespoons of the product in 10 liters warm water, mix thoroughly to avoid lumps, and water the plants after the liquid has cooled.

But if traditional methods did not help you, try using effective fungicides. So, the most effective remedies against this fungal disease are such remedies as Forecast, Vitaros and Previkur.

Many gardeners complain that petunia leaves become covered with a white coating. Why is this happening. Let's try to figure it out in this article.

Petunia leaves become covered with a white coating for several reasons. In this article we will look at the main causes of this unpleasant phenomenon.

White plaque is not a very good symptom. It indicates petunia disease.

If the petunia leaves are covered with a white coating, then most likely it is powdery mildew. It could also be downy mildew.

How to distinguish powdery mildew from downy mildew?

Powdery mildew is one of the most common diseases of plants, including petunias. This disease is fungal. It manifests itself in a white coating on leaves, stems and flowers. If no measures are taken, the plant will dry out and die. The following factors lead to the occurrence of powdery mildew:

• High air humidity.
• Large temperature changes.
• Lack of nutrients.

Downy mildew manifests itself practically. In order to distinguish downy mildew from real powdery mildew, you should pay attention to plaque spots. Also, true powdery mildew seems to suffocate the entire plant, and downy mildew affects the green parts of the plant. Downy mildew has a very characteristic “fluffy” appearance. white coating.

You can also distinguish by conditions. Powdery mildew appears in conditions high humidity, and false appears in conditions of lack of moisture.

Fighting powdery mildew on petunia: what to do?

If you determine that your flowers are covered with a white coating due to powdery mildew, then the following remedies are perfect for the fight:

• Fundazol;
• Topaz;
• Acrobat MC;
• Previkur;
• Speed;
• Vitaros;
• Amistarextra.
• Fitosporin.

These drugs help quite well with powdery mildew. Follow the instructions on the package.

Control of downy mildew on petunia.

If the petunia leaves are covered with a white coating due to downy mildew, then the following remedies can be used:

• Solution of iodine and milk. (Drop 10 drops of iodine into 1 liter of milk and mix in 10 liters of water. Spray petunia with this solution). This product helps very well.
• Polycarbacin.
• Copper oxychloride.

All these products can be easily purchased at a gardening store. They help a lot and the white coating will disappear very quickly.
