Treatment methods
Most violet diseases are incurable, and therefore little helps in the fight against them. Infected flowers are removed from other plants and destroyed along with the soil ball.
However, if there is hope for the salvation of at least one specimen, then fungicides will come to the rescue.
The drugs are aimed at destroying fungal spores and fighting infections. In addition to proper processing, violets need to change the conditions of detention:
- reducing moisture levels by reducing watering of flowers;
- placing violets in a warm and lighted place;
- removal of the top layer of the earth, in which fungal spores can live.
What to do, if
Sometimes novice florists have questions, the answer to which can be given by their more experienced colleagues.
Drops appeared on the violet
The question is often asked why droplets of liquid formed on the violet, there are 2 answer options:
- if these are drops of water at the edges of the leaves and they appear in the morning, then high humidity can cause their occurrence (after watering, the plant releases excess liquid that accumulates in the form of drops);
- if the drops look like sugar syrup, then, most likely, scale insects have started on the plant.
The violet has lumpy leaves
When novice violet lovers buy a young plant, they see smooth, even leaves. After a while, you can see that the leaves have become hard, bumpy, the rosette has become very thick. This may be due to overexposure, when the plant is at the window and most of the day is well illuminated by the sun. To eliminate this problem, the violet bush must be sent to the east window or shaded with something.
Midges started
If you notice that midges have started over the violets, there may be several reasons:
- excess moisture due to excessive watering;
- high air humidity;
- the use of organic fertilizers such as humus, tea leaves;
- rotting old leaves;
- the use of garden (unsterilized) soil for the preparation of soil mixture.
The larvae of gnats, hatching in the ground, feed on rotting organic particles and damage the roots of the plant, causing considerable harm to it. If a midge appeared on violets, how to get rid of it:
- spray the flower with a pink solution of potassium permanganate;
- add wood ash to the ground;
- Dissolve 10 g of soap in 0.5 l of water, pour over the soil in a pot.
How to care for a violet at home
Diseases are most often the result of improper care of indoor plants. After all, the wrong content of the flower most often leads to problems in its development. A person who does not know how to water and transplant a plant can make many mistakes that will be visible in its appearance very soon. Therefore, let's start with what should be the care of a violet at home. Diseases from the photo will be considered after that.
Most flowers need to be repotted periodically. Otherwise, they begin to grow poorly, do not bloom and simply wither before our eyes. The reason may be too tight a pot, which limits the development of the plant. Also, with a rare transplant, the soil can become covered with a white bloom. This means that it does not allow air to pass through well. In such soil, the plant can become seriously ill. If you notice pests in the soil, then a transplant is necessary. By changing the pot filler, you can get rid of unwanted microorganisms.
It is necessary to transplant the violet by the transshipment method so as not to damage its roots. The new land should be moderately damp. After transplanting, make sure that the soil does not sour and does not become salted.If you see such signs, immediately repot the plant again, it will not be able to live in bad soil: it will either rot or not bloom, which is also unpleasant.
With a lack or excess of light, leaf diseases may appear. Violet reacts very sharply to light conditions. If too little sunlight reaches it, then it may simply not bloom. Too aggressive rays can provoke yellow leaves or even their falling off.
Watering the violet must be done carefully. Any drop falling on its leaves can provoke putrefactive processes.
Also, do not give the flower too much moisture, otherwise the roots will start to deteriorate. The best way to add water to the pan, from there the flower will take as much as needed. The frequency of watering should depend on the indoor climate. If the soil in the flowerpot dries up too quickly, then you need to water it more often, and vice versa.
If you have a lot of violets, then watering can be organized using a large bowl. Water is poured into it, and flowerpots with flowers are placed on top. After a while, they are returned to their usual place.
Watch also the humidity of the air. If it is too high, the violet may start to rot. The problem will start with leaves that cannot survive in too humid conditions.
Fertilization is necessary, but here it is important not to go beyond measure. If fertilized too often, the plant may suffer.
In such cases, leaf curling, lack of flowering is often observed.
Decay is generally characteristic of a violet. It can happen if you transplanted a flower and the soil does not fit. Also, putrefactive bacteria can appear on the leaves if the plant has not been watered for a long time, and then immediately received a lot of moisture. That is why these flowers are called delicate, because they can die due to the most insignificant reason.
Application of fungicides
The most effective and fastest way to treat powdery mildew violets is fungicide treatment. Before the procedure, the flower is removed from dust and dirt by rinsing under running water. Spraying should be abundant, until the liquid drains from the leaves.
The drug "Baylon"
Fungicide of systemic action "Baylon" effectively fights powdery mildew, rot, scab. Its active ingredient is Triadimefon 250g / kg. It is used in the fight against fungus on vegetables, fruit trees, flowers. The product is available in two forms:
- concentrated emulsion (10%);
- water soluble powder.
The drug is applied by spraying a solution (1 g per 1 liter of water). Apply to all sick and healthy violets. The procedure will stop the spread of the disease. Leaves are processed on both sides. The rest of the solution is poured into an earthen lump. They will act on the disease by being absorbed into the roots. The product enriches the violet with zinc, this element is responsible for the health of decorative flowers. The effect of the fungicide is noticeable at 4-5 days. The effect of the drug lasts for two to three weeks.
Means "Topaz"
Fungicide with the active ingredient penconazole 100 g / l is used in the treatment and prevention of fungal diseases. It goes on sale in the form of a liquid concentrate. The drug is most effective in the early stages of powdery mildew. Ampoule "Topaz" (2 ml) is designed for dilution in 5 liters of water. The resulting solution is used to treat the rosette of the plant, wetting the leaves on both sides. With extensive damage to the flower, the concentration of the composition is increased. The number of treatments depends on the state of Saintpaulia, the interval between sprays is two weeks. To avoid resistance and enhance the effectiveness of action on pathogens, alternate the use of "Topaz" and "Bayleton".
Pros:
- has no smell;
- does not leave streaks on the leaves;
- protective effect - two weeks;
- safe for people and animals.
Usually one treatment is enough to completely cure flowers.
The drug "Fundazol"
The tool destroys a large number of pests and pathogenic fungi. It is used to treat powdery mildew in violets and other indoor flowers. The release form is a powder that is slightly soluble in water. Any part of the plant can be treated with the drug; high efficiency is manifested when absorbed through the roots. The active ingredient is benomyl, a compound that inhibits the ability of fungi to divide. Dosage: 20 g per 1 liter of water.
Safety measures - the drug is toxic to humans and animals. The processing of the plant is carried out with gloves, glasses and a respirator.
Prevention of diseases on violets
To reduce the risk of infection of violets with various diseases, following some recommendations for their care will help:
- Plants that have just been bought and brought home must be "quarantined" away from other flowers.
- Do not reuse soil left over from other plants.
- Before transplanting violets into a new container with soil, it is necessary to sterilize the soil - calcining or freezing.
- The most common reasons for the growth of pathogenic bacteria are improper care of Saintpaulia - insufficient light, low temperatures, drafts and excessive watering.
- Do not use soil from greenhouses with many types of flowers or greenhouses, as it can be contaminated. Better to take the land from the forest, away from the city.
The diseases that violets suffer from can be very dangerous. If treatment is not prescribed on time, then Saintpaulia and neighboring species can become infected and die.
They are especially demanding in terms of care and conditions - soil, temperature, feeding, etc. varietal violets, for example "Raisins" and "Chimera". They immediately stop blooming and, if not given proper attention, may die.

Violets - diseases and pests
We analyze diseases of violets on leaves, which are caused by various parasites, such as ticks, aphids, and scale insects. Explanations from specialists with photos and a detailed description of the treatment.
The violet does not grow leaves at the point of growth. Over time, they lose their color and become yellowish-grayish, blacken and die off. The disease affects both young and old plants. The cause of the violet disease: spider mite. As a result of its vital activity, a plaque appears on the leaves of the violet, the latter deform over time, lag behind in growth, turn yellow and die off. Treatment of the disease: a warm shower and treatment with acaricides. Contrary to popular belief that the leaves of the uzambar violet (Saintpaulia) cannot be wetted with water, a plant that infects a spider mite is given a warm shower. So that after a shower the leaves of Saintpaulia do not turn yellow, the flower is transferred to a bright and warm room (the optimal temperature is + 18 ... + 25 degrees), where there are no cold drafts. This is followed by treatment with phytoverm, acarin, neoron preparations of the maximum concentration suggested in the instructions. You do not need to cover the violet with a bag. It is not recommended to use Actellic and Fufanon preparations indoors.
Plaque on the leaves of the violet in the form of ordinary flour indicates that the plant has been affected by powdery mildew (real or false). When the violet is affected by powdery mildew, the leaves and flowers of the plant are covered with a bloom in the form of flour, the plant lags behind in growth. If downy mildew has settled on the flower, then light green or brownish spots are added to the bloom in the form of flour. Over time, the leaves of the violet deform and it dies.
How to treat powdery mildew on a violet? Powdery mildew is a common disease of violets that spreads through the air as spores, as it is a fungus. Its development is facilitated by high humidity and low air temperature. Therefore, when starting to treat plants, it is necessary to increase the temperature of the content. Then violets and plants standing next to them are treated with Topaz or a similar preparation. Processing alone will not be enough.
Violet flowers and leaves are covered with sticky drops. On the reverse side of the leaf plate, there are black and green insects. Domestic violet disease - aphid. The insect infects the plant in conditions of high temperature and air. Treatment of the disease: repeated treatment with an interval of 7-10 days with insecticides. It can be Aktara, Fitoverm and others.
Brown spots on violet leaves may indicate systematic waterlogging of the soil. But if brown spots appear on the leaves of several plants at once, this indicates fungal diseases.
Fusairosis (tracheomycosis). The active stage of the disease occurs in the ground and affects the root system. The fungus then spreads to the green part of the plant. Spots appear on the leaves and cuttings of violets of a light brown color, moist to the touch. The stalk of the plant rots. Such a plant can no longer be cured and, in order to avoid contamination of the entire flower collection, it is thrown away. Then the entire collection of violets is subject to prophylactic treatment with phytosporin solutions. Solutions of tetracycline preparations (500 mg per 1 liter of water), trichopolum (1 tablet per 2 liters of water) also help. To prevent violets from being affected by such a disease as fusairosis, you cannot overmoisten the soil, keep flowers at low temperatures, make sure that the soil in the pot does not become compacted and sour.
Gray rot. The spots on the leaves of the violet of a brown color, covered with a grayish bloom in the form of mold, indicate that the plant has been struck by gray rot. It appears if the plants are kept at low air temperatures (+16 degrees and below), high humidity, and abundant watering. The development of gray rot is favorably influenced by an excess of nitrogen in the soil. In order to prevent, violets are fed with liquid, complex fertilizers, the room where the flowers are placed is regularly ventilated. But you need to remember that cold air currents can destroy them. At a low temperature of the content (below +18 degrees), watering is significantly reduced. Violets should not be sprayed frequently. It is enough to put a bowl of water next to the pots.
If spots of gray rot appear on the leaves of the violet, you need to treat it like this: isolate all flowers affected by the disease, normalize the temperature of their plant content and watering. Remove all leaves along with cuttings that have been affected by the disease. This is followed by treatment with systemic fungicides. Experts recommend using the drug with the active substance fenexamide - teldor, you can use sumilex, switch, topaz.
Diseases
Powdery mildew
Violet leaves are covered with a white coating, similar to dust or flour, but do not disappear when washed or sprayed with water. Promote active propagation: lower temperatures and increased air humidity.
Treatment by spraying with preparations "Topaz", "Saprol", "Baylon".
Late blight
Promotes the development of this disease - plant hypothermia. lack of lighting and excessive watering. When affected by this disease, the foliage of the violets droops.
Treatment: The violet can be saved early on by ripping off any infected limp leaves. Next, the violet should be transplanted into a different soil, having previously cut off all decayed roots. Treatment with Fitosporin.
Fusarium
Often manifests itself in the cold season, conditions conducive to the appearance: excessive watering, excessively heavy soil, too spacious a pot, sudden temperature fluctuations, watering with cold water.
The leaf stalks turn brown and fall off. The roots darken and rot.
Treatment: as with late blight. For prophylaxis - with a solution of "Fundazol"
Gray rot
Careless watering (falling of water droplets on foliage and petals) contributes to the appearance of the disease, they quickly turn brown and rot.
Treatment: removal of diseased leaves, treatment with "Fundazol".
We hope that this article about what diseases and pests of violets are, will help you save your green beauties.
And finally, advice, be careful when buying new plants, do not rush to put the purchase right on the windowsill next to the rest of the plants. Wait a while and make sure it is not infected.
What does it mean if violet leaves become lethargic
A situation can become dangerous for the life of a flower when the stem begins to lose its elasticity, the aerial part of the indoor flower suddenly becomes sluggish. There may be several reasons for this wilting:
- a fungal infection has got into untreated sections;
- serious mechanical damage;
- the appearance of pests that feed on Saintpaulia juice;
- the wrong temperature regime for the plant;
- diseases of late blight and fusarium, in which rust-colored spots are characteristic.
Note! If a transplant was recently carried out, then the cause may be a burn of the plant root with fertilizers added to the soil. In this case, it is impossible to save Saintpaulia.
The leaves have blown
The question often arises when a violet has sluggish leaves, what to do to resuscitate the plant. The best solution would be a transplant. At the moment of sprout extraction, all parts of the root and aerial system can be examined. Remove the soft parts and transplant the rest of the seedling into a new container.
Insect pests
Mealybugs
Mealybugs feed on young peduncles, can live in leaf axils and soil. They multiply actively, being saturated with plant sap, which is almost completely deprived of nutrients.
Signs of damage to violets by mealybugs:
- discoloration of leaves to grayish or yellowish;
- leaf plates lose their shine, become less elastic;
- new leaves grow deformed and small;
- the plant stops growing;
- decay of roots and stems begins.
If you feel that the soil in the pot smells something like mushrooms, then it is infected with worms. By the way, you can even see these pests. They look like white fluff.
Treatment for mealybugs is insecticidal treatment.
Translucent insects with a black, green or red body are aphids. It feeds on the plant's intracellular sap, depriving shoots and leaves of nutrition and causing them to die off. Aphids can be removed by washing all the ground parts of the plant with soapy water, and then rinsing in the shower, preventing the soil from washing out of the pot.
There are several types of mites that can harm violets.
Cyclamen mites are almost invisible. Their appearance can be diagnosed by the yellow traces on the plant. Leaves and young leaves are food for cyclamen mites.
Spider mites feed on violet leaves. In the place where the spider mites dined, reddish punctures with a thin cobweb appear.
The treatment for ticks is insecticidal.
Mites can severely damage the plant. In addition, they carry various diseases.
Common diseases of Saintpaulia with a photo
Powdery mildew
Many indoor plants are susceptible to this fungal disease. It manifests itself by the appearance on the leaves of a white bloom. However, it is quite difficult to remove it from the flower. High humidity and low room temperature contribute to the formation of powdery mildew. The following drugs will help to cope with this disease: saprol, byteleton and topaz. Moreover, it is recommended to alternate them. Sulfur is also considered an excellent powdery mildew remedy. First, she needs to powder the violet, and then cover the flower with plastic.
Insidious late blight
When Saintpaulia is infected with this disease, the main thing is to start treatment on time, otherwise the plant will quickly die. Late blight affects the stems, as a result, they acquire a brown tint. With such a disease, the leaves fall off strongly, exposing the trunk.Its appearance is provoked by a fungus that penetrates through the affected areas of the flower or the root system.
During treatment for late blight, the violet will have to be pulled out of the pot and the root system should be examined well. Any damaged roots should be removed. It is quite simple to define them - they have a brownish appearance. When the roots are completely affected, it is better to cut off the stem with a razor. The resulting stalk can be rooted in water under plastic wrap. After that, it is advisable to plant the violet in new soil and a pot.
Dangerous fusarium
This disease occurs most often if the grower violates the conditions for growing violets:
- Uses an overly spacious pot;
- Does not protect the plant from sudden temperature fluctuations;
- Pours with too cold water;
- I planted a flower in a very heavy ground.
All this leads to the fact that the shoots of the flower are affected by the Fusarium mushroom. It leads to decay of leaf stalks and roots. It is easy to detect the disease, because when infected, the leaf stalks turn brown and fall off, and the roots darken and separate from the ground. To prevent the occurrence of such a disease, it is necessary to periodically water the violet with fundozol. Affected indoor plants should be treated with fungicides, removing all dried flowers and decayed areas.
Gray rot
If a fluffy coating of a brownish-grayish hue has formed on the violet on the processes, flowers and leaves, then this indicates the appearance of the fungus Botrytis. Such a disease in a short time is able to cover the entire flower, leading to its death. Gray rot usually penetrates along with plant residues in the soil. It quickly infects other plants, and botrytis spores can be found in any soil. It is for this reason that the earth should be frozen in the freezer and spilled with a solution of potassium permanganate.
To prevent such problems, it is necessary to immediately remove the brown parts of Saintpaulia, and apply fungicides to the affected flowers. Do not feel sorry for rotten plants, they should be immediately thrown out along with the soil. As a preventive measure, do not overfill the uzumbar violet with water, besides, do not allow sudden temperature jumps.
Rust
This disease of violets is caused by rusty fungi. If the plant is affected by rust, then yellow-brown tubercles appear on both sides of the leaf. For the spores of these fungi to ripen, a little water on the leaves is enough, as well as a humid and warm microclimate in the room.
But remember that the specks on the leaves of the violet are not always a symptom of the disease. Yellow dots can appear on the plant if it is in an awkward location. Insufficient lighting, drafts and direct sunlight quite often lead to holes and yellow leaves on them.
With an excess of fertilizers, yellowing of the leaves is also observed, so it is imperative to observe the proportions during the preparation of fertilizers for violets, and also adhere to the advice of agricultural technicians on their use.
White bloom
On the ground
If there is a white bloom on the violets - what to do, how to treat it? To begin with, it should be clear that plaque is different. If such a plaque appeared only on the ground, then the grower has much less reason to worry.
White bloom on the ground can have different origins.
White bloom on the ground has several reasons:
- physical evaporation of water creating a salt crust of white or white-yellow color. The reasons are in the heavy mechanical composition of the soil, which leads to high capillarity of the soil and the suction of water to the upper layers of the soil. Either poor drainage, which causes excess evaporation;
- watering errors: infrequent or overflow;
- over-fertilized soil as a result of errors with the dosage of top dressing;
- hard water;
- dry air, leading to increased evaporation, which provokes the removal of salts to the soil surface;
- fungal microflora caused by excessive watering.
Rarely, but occurs, mold living in the ground.
To get rid of white bloom on the surface of the soil, it is necessary to find out the reason for its appearance and eliminate it in a timely manner, preventing it from spreading to parts of the plant. Fungal diseases are best treated with chemicals or a complete replacement of the soil mixture.
On flowers
Usually, the appearance of white bloom on buds or flowers occurs when the heating is turned off. The room becomes cool and damp, which causes the appearance of fungi.
If the mold on the flowers covers a small area and the damage is not too extensive, then fungicide treatment can be dispensed with.
In case of neglect or rapid development, it is better to remove buds damaged by the fungus and process the plant.
Conclusion
Most often, plants get sick in winter when:
- It's cold on the window;
- And the plant is at rest.
At this time, we continue watering, but the plant does not have time to absorb all the moisture it receives, and it stagnates. This is where many soil pathogens arise.
Do not forget that cleanliness and order are important not only for people. Do a spring cleaning at least once a month. The windowsill, shelves, shelves all need to be washed! Dust and dirt clog pores and interfere with normal gas exchange.
Don't panic if your violet leaves turn white. As the sockets are updated, they will change. And if you fix the problem that caused the lightening, then the new ones will be green and healthy. The main thing is that this ailment should be noticed and eliminated in time.
