Real mildew: frequent and wrong, manifestations, control measures
Real mildew is a kind of many diseases that are susceptible to flowers, plants and vegetables. Sometimes it is also called linen or ashtray, because of its appearance a white rash on the leaves.
What is mildew and the conditions for his appearance?
The disease is mushroom-like, the cause of its occurrence is erysiphos or mildewed, of which there are about 700 species. A large part of the crops are susceptible to the disease, only a small percentage has a resistance to it. The most sick are grapes, gooseberries and roses. Peach, beets, pumpkin, cereals are also susceptible to mildew. Signs in all plants + are the same, while pathogens are different. So Sphaerotheca Mor s-Uvae loves gooseberries and black currants, Blumeria Graminis attacks grain, uncinula necator – grapes and erysiphe cichoracearum – zucchini and cucumbers.
The first, most striking symptom is a white covering on leaves, leafsticks, young drives and stems. Moisture drops can appear on the surface.
The disease contributes to the quick wither of the plant and the disturbance of photosynthesis.
In addition, the real mildew’s cracks form cracks on the leaves, through which other pathogens can penetrate, which leads to a new infestation.
Plants of this infection are most common in persistent rainfall, high humidity and also due to an excessive amount of nitrogen in the soil.
Improper watering can cause diseases.
Mr. Dachnik informs: General rules to combat the real mildew
When the first signs are found, the withered plant parts must be removed. After treating sick bushes and the ground around you with a fungicide, this will prevent the further development of mushrooms.
In the case of houseplant diseases, treatment takes place to a characteristic as in the field. After removing the infected parts, the top layer of earth must be removed from the container in which the culture is grown because it contains a mushroom colony. Pour a new one in its place and treat it like the plant itself with a fungicide.
As a preventive measure, you must carefully follow the rules for the care of a flower.
Differences between real mildew and false mildew
Powls of mildew grow on the surface, when the disease develops, they first cover the outside and only then the inside (mold looks like flour). The leaves roll in, but rarely fall off. False mildew always develops from the lower inside, graywood is visible from below, and a yellow or light brown surface is visible from above. The leaves rarely dry out, they become stained, turn black and then fall off.
Real mildew on vegetables
As mentioned above, the disease also affects vegetables, especially mushrooms, beets and pumpkins.
Real mildew on cucumbers is treated with fungicidal solutions (Topaz, Oksihom). Folk remedies are also suitable, for example 1 liter of kefir or sour milk in a bucket of water, process three times in three. In addition to this solution, you can also use sulfur powder in the ratio of 30 g per 10 m², colloidal, 30 g per bucket of water.
Among other things, combat methods: infusion of royal candle, marig flowers, solutions of potassium perhanging in water, soda with soap. On our website you can read more about all means, including the folk remedies.
Grow house tomatoes are often affected. In order to prevent possible diseases, disinfection with fungicides is required.
The disease often manifests itself in the stage of planting seedlings, while the leaves on the edges begin to dry out. Wrestling does not differ from cucumbers.
More drastic measures are required. Remove all infected leaves and grab the earth carefully. Then spray the area with a solution from soda or chemicals Kefalon, Carboran.
You can destroy the infection with a solution from soda or fungicides. It takes 4-5 sprays, nothing less.
It is more often affected by the wrong mildew (false mildew). With a normal lesion, it begins outside the green mass and with a wrong inside.
The wind or raindrops are worn wrong. However, the conditions for its development are exactly the same as for the usual. Diseases can be combated by destroying the affected parts and spraying with a solution made of soda or blue vitriol with the addition of soap. So you cook the first: take 10 liters of hot water (bucket), add 100 g detergent and rub it on a grater, 2 tablespoons. Stir the tablespoon of soda with a film. Spray 3 times a day, interval – about a week.
Leaves and stems of the harvest are affected, a characteristic whitish coating appears on the surface.
The disease quickly develops in hot climate and high humidity.
Prevention measures include earlier disembarkation.
The use of energen is effective for the first signs of damage. 1 m² area is sprayed with one liter of solution: 10 drops of the drug per 50 ml of water. Make sure to repeat in a week and a half.
As with peas, leaves and stems are susceptible to diseases. If a white covering occurs, the affected parts should be removed immediately.
A regular spray with fungicides or folk remedies is recommended as a preventive measure.
Powdery dust control on bushes and trees
Powdery growth often affects fruit bushes and trees.
It is impossible to delay the treatment, since in the second half of the summer the entire bush and possibly infected nearby.
Combating is in the timely removal of infected parts with subsequent spraying with fungicides. You can also use folk remedies, but only if you know all the properties of the plant, otherwise a different disease can develop.
The situation is exactly the same as with currants. Soda asha is used as folk methods with kefir, wooden ash and cow. Gaupsin is very popular among chemicals.
The disease, for which grapes are susceptible, is called Oidium and refers to real mildew. The symptoms are exactly the same as with the original disease, it develops at high temperature and moisture.
The fight is no different. Timely removal of affected leaves, treatment with fungicides. It is also recommended to dig the soil carefully.
Berry damage is noticeable on the ruffling edges of the leaves, which take on a bronze tint, appear a white rash and a musty smell.
As a preventive measure, it is necessary to follow the growing rules. It is also recommended to spray the plant with a suspension from colloidal sulfur (1% solution). This can only be done after the end of the flower or after the harvest.
If prevention does not help, use medication such as Fundazole, Topaz.
The difference to other plants is that the apple tree does not die during an infection, but loses 50 % of yield and also deteriorates the taste of the fruits. A side effect is the poor resistance to low temperatures.
In order to get rid of the disease, the best solution is to use soda that has to be mixed with soap. Dissolve 50 grams in 2-3 liters of water, then fill up to 10 liters (bucket) and add 10 grams of soap. Colloidal sulfur (30 g per bucket of water) is also good. Regularity – three times a day every 3-4 days.
Real mildew on garden flowers
Even the beautiful representatives of the garden did not escape this problem.
If symptoms of the disease are determined, the leaves affected must be removed. Dine the entire bush with a strong defeat. Spray plants or leftover flower nearby with a solution made of colloidal sulfur (20-30 g per bucket of water).
Signs are premature wrinkles of leaves, the formation of a felt coating on the stems.
The disease does not let the roses grow any further and will finally destroy them. If symptoms are found, it is necessary to spray with already known solutions. In detail: real mildew on roses: description and control measures
As a preventive measure, keep the earth around the roses as clean as possible. It shouldn’t have weeds.
The disease provokes the formation of putrefaction, which contributes to the sudden death of the flower. The symptoms are the same – a whitish rash. Control methods – removal of infected parts, spraying of the survivors, thorough ditch of the soil.
With this flower, the buds are most susceptible to the disease.
The reason for the occurrence of mushrooms is often an excessive nitrogen content in the soil. To remove this problem, you must first carry out a complete analysis and then apply fertilizers that stabilize the content of different substances in the soil.
Real mildew on houseplants
Housing plants are no less at risk than those that are grown outdoors. In your case, however, it is much more difficult to defeat the disease.
Veils in real mildew
When identifying signs, as always, you must first remove all infected parts and then spray the survivors. After you have removed the top layer of earth from the container, the thicker, the better, there are mushrooms.
Set fresh, disinfected and fertilized instead of the cleaned.
In some cases, however, a complete transplanting of the plant into another floor is required if the disease has developed significantly.
As a preventive measure, it is worth paying more attention to water. Floods are the most common cause of real mildew. Too moist, used air and excessive use of fertilizers containing nitrogen are also not acceptable. However, it is clear that all plants are different, so simply follow the recommendations for growing your special flower.
This is a kind of illness. It is most frequently found on vegetables.
It usually manifests itself in August when the temperature drops to rather low indicators at night. For this reason, condensate is formed, which in turn is an ideal environment for the spread of unwanted disputes. In addition, a lack of potassium, phosphorus in the soil can also cause the disease.
It is best to use stable varieties (Valentius, Orion, satellite, hazelnut vexion).
If the first signs appear, it is necessary to immediately exclude organic fertilizers and top dressing based on nitrogen. Reduce irrigation to prevent the possibility of further reproduction. Spray 1% Bordeaux liquid. You can eat onions in 20 days. After removing the harvest, treat the soil with fungicides.
The struggle is to be badly damaged and to remove the use of fungicides and folk remedies. Help a lot:
- Dairy products (sour milk, kefir, yogurt) in part of 1:10 with cold water;
- Handled once a week with wood (50 g per 1 m²);
- Rleed grass, pour half of the weeds with hot water, exist for 2-3 days, strain and use for spraying.
The causes is plasmopara halstedii. The disease affects growth, the sunflower is delayed behind the maturation plan, the root system stops developing. Most of the time this leads to death, but it is also possible that the plant will bloom, but much worse.
Funizids are used to fight.
Everything is very serious about grapes. If you do not pay attention to any noticeable signs in time, this can lead to the loss of the entire vineyard. It is therefore necessary to carry out regular prevention, although there are no signs.
With the colors, the disease develops extremely quickly, literally harmful in one day of irreparable damage. Solutions such as Tanos, Previcur and Ridomil are recommended as existing funds.
A sign is the appearance on the leaves of the yellow spots, dilapidation.
To avoid this, the seeds must be subjected to hydrothermal treatment before planting. To treat treatment, carry out a 5-session spray with a solution of 1% bordeaux fluid or fungicides.
Real mildew. Causes and methods of the struggle
Florists and gardeners often hit a whitish badge on their plants, which does not look hazös, but in reality it is a serious fungal infection. This badge is referred to as mildew or, as it is also called linen or ash. The disease is considered one of the most freely found and influences different types of plants such as flowering, vegetables, berries and occasionally fruit. There is an attack thanks to bundl e-free mushrooms, which are called ERYSIPHALES in Latin. It occurs on the leaves, but in a neglected form affects the stems and fruits. There is such an infection as peronosporosis (wrong mildew). They are often confused because the external signs of manifestations are identical.
The problem is that despite the death of the affected fruits, the mycelium does not disappear, but refuge under the fallen leaves, in the ground and under the bark. The Myzel is waiting for the cold season in this state and wakes up with the first warmth and spreads out on the rising plants and affects their stems. Signs of the manifestation of the disease in plants are similar, but pathogens differ in species. For example, American mildew is caused by 3 types of balls.
The infection develops pretty quickly, especially if it is favored by a high humidity of the environment, for example in greenhouses. The ripening period of the dispute is taken into account from one month to three. When the weather is warm and moist, the real mildew grows faster and actively affects the plants. Low resistance to peaches, grapes, gooseberries, cereals, roses, pumpkins and beets.
Causes of real mildew
A characteristic of the disease is the transmission of spores through the air. In fact, they are constantly in the air, but certain conditions are required for their development. Here are the reasons why real mildew can arise:
- Air temperature from +17 to +25 degrees, humidity in the range of 60-80%. Most of the time there are such indicators in greenhouses;
- weakened vegetable immunity, which is reduced by strong pruning of branches;
- greatly increased nitrogen content in the soil;
- if fruit trees are planted too densely. This increases the humidity and air circulation decreases;
- If the soil is excited.
Real mildew symptoms
Belle is activated with the advent of heat and freezes in autumn. If you look closely, you can already see the plaque in the stadium of budget. It looks like a bluish-white dust that is close to a stem or leaf. Due to such a dense formation, the inflorescence fades quickly and disappears.
If nothing is done, the parasite gradually changes its color and becomes gra y-brown. The color changes to red on plates and cuttings. The mushroom inhibits the development of the sprout strongly and leads to the rotting of the leaves.
Territorial location of the real mildew
Real mildew is almost popular throughout Russia and the CIS countries. The highest degree of damage is in Armenia and Moldova, Central Asia and Transcaucasia and is 90 %. Transcarpaties, Georgia and Kyrgyzstan are a little less susceptible to disease activities. Here the number reaches 60 %. The Black Central Strip and the Baltic States define the spread of the mushroom to just 40 %.
Common combat methods
It is most difficult to treat mushroom plaque in the active running phase. In addition, the forecasts can be disappointing. Experts therefore recommend that the disease do not start and get rid of it in the early stages of occurrence. It is even better to take preventive measures. In order to minimize the risk, it is advisable not to flood the plants, but to use a special scheme for planting, which is designed for the free pass of air masses between the plants.
Fruit trees need rejuvenation. This procedure enables you if it is carried out correctly and without excess to eliminate the thickening of the crown and thereby prevent the manifestation of mildew. To prevent the spores of the mushrooms from remaining in the ground, you should regularly remove dirt and leaf and flower remains on the construction site. It is important to prevent the development of weeds, form dense vegetation and hinder free air circulation.
It is difficult to expect that we can prevent mildew’s occurrence and cutting the crown. Experts use chemical treatment as a preventive measure. There are fungicides that are rather aggressive means, as well as environmental connections such as copper sulfate and copper oxychloride. Sometimes Bordeaux mixtures and other similar connections are used. As a rule, around 3 times are processed from March to October.
Fertilizers also play an important role. They enable us to strengthen immunity and increase the resistance of plants with diseases. Potassium salt and superphosphate are great for these purposes. It is calculated in 15-20 g for a tree.
Below you will find various methods for treating mildew with special medications:
- The use of fungicides such as bailon, quadris, rayok, speed, inclination, topaz, thiotive jet, foundazim, foundationazole. Topaz is taken in part of 2 ml per 10 liters of water. Before use, you must read the instructions and take security measures for the operation of the chemical recipe. All medications are instructions in which doses and processing methods are written.
- The use of biofungicidis. They are inferior in the effect of fungicides, but environmentally friendly. Fitosporin-M, Alin-B, Gamair, Pseudobacterin-2, Planris are known. Putty cans depend on the degree of infection of a certain culture. Incidentally, Ftosporin and Gamaire actively influence the manifestation of peronosporosis.
- Spraying with copper preparations – Bordeaux liquid is taken 1 teaspoon. for 10 liters of water or chloride in the same ratio.
advantages and disadvantages
Chemical methods for processing defects are larger than the advantages:
- Phytotoxicity (plant growth is inhibited);
- The ovary can fall;
- Reduced immunity in plants against pathogens;
- Environmental pollution;
- Possible negative consequences through the consequence of the contact with various elements in the soil;
- destroy useful ethnophaun;
- A few years later, pests develop resistance to fungicides and are immune to later treatment.
- Bad effect on insect orders.
The advantage is one, but significant: the medication quickly and qualitatively eliminate the focus of the disease and prevent their appearance throughout the season.
In order for the folk methods to work, it must be used on the first sign of the occurrence of a badge. They act gently for plants and do not poison the fruits, and therefore their use is harmless to humans. Below you will find several popular popular opportunities for the fight against powder mildew:
- The most popular method of fighting the parasitic fungus is the s o-called “milk cocktail”. 7 liters of water and 1 teaspoon are taken for 3 liters of milk serum. Copper sulfate. All ingredients are mixed thoroughly and sprayed into damaged seedlings. Or as an option 1 ml serum, 1 ml iodine and 9 liters of water. Iodine is seen as an active drug for false mildew.
- The onion tincture is made from 200 g onion shells, which is poured with 10 liters of hot water. It is passed for 2 days, then it is filtered and sprayed on the plants.
- A mixture of calcified soda and soap is produced as follows: 60 g calcified soda is rubbed on a bucket of water and 30 g soap with an antibacterial addition. The composition is well mixed until the soap has completely disappeared. Then spray plants with a parasitic mushroom three times with one interval per week.
- 1 kg ashes on a bucket of water is taken and stirred. The solution is infused and filtered for a week.
- A quick way to use ashes takes place as follows: 200 grams of ash per bucket of water
advantages and disadvantages
- Environmental friendliness;
- Accessibility of the components of the ingredients;
- A positive effect on a parasitic disease after several treatments.
- small efficiency after the other;
- To create a solution, you sometimes need a lot of time.
In the following you will find a video overview in which methods for combating mildew are presented in powder
Reviews of the owners
The parasitic mushroom attacked all of my tomatoes and only then added the meaning of the problem. I decided to use Fitosporin’s biological product and the problem was no longer worried. The badge disappeared and no longer appeared. This is not that, fätze also disappeared to the fruits. Manufacturers say that the drug is harmless to humans so that they can certainly spread the fruits.
