A gray coating appeared on the leaves of cyclamen. Gray mold treatment

Of course, sterilization of the soil helps to get rid of most of the soil living organisms. As a preventive measure, the plants are also watered with a pink solution of potassium permanganate, which well suppresses a bacterial infection and partially a fungal one. In addition, you should not feed plants with fertilizers with a high nitrogen concentration, as overfed plants become susceptible to infections.
The most dangerous among plant diseases is rot. Under certain conditions, they affect all indoor plants. Most often this is due to excess moisture at low temperatures, when the plant's water consumption is minimal.

A well-groomed cyclamen is very seldom distressing, as resistance to attack by pathogens is the result of its healthy growth. It's sad if favorite plant suddenly falls ill. For 25 years of keeping cyclamens, I noticed that mainly old cyclamens are affected by fungal diseases. The age of old cyclamens, in my opinion, is plants older than 6 years. Such cyclamens have a large tuber, and their resistance to diseases is reduced. The occurrence of cyclamen diseases contribute high humidity, high or very low temperature, excess nitrogen fertilizers. Therefore, it is necessary to provide plants optimal conditions growth and development, high agricultural technology, complex preventive measures to protect them from diseases and pests.

The most common diseases of cyclamen are fusarium, gray mold (botrytis), brown rot (ramularia), root rot (pytium, rhizoctonia, etc.). Of the bacterial diseases, wet rot is very dangerous.

Fusarium wilt

Fusarium is a fungal disease caused by the fungus Fusarium; under its influence, the vascular system and tissues of the plant are affected. The disease has several names: "shrinkage", "core rot", "dry rot". With Fusarium wilt, lesions and death of plants occur due to a sharp violation of vital functions due to blockage of vessels by the mycelium of the fungus and the release of toxic substances by it. Pathogens remain in the soil for a long time plant remains, enter plants through root system and lower part stem.
Symptoms: outwardly, the disease manifests itself in yellowing of the leaves, which begins with the tops. Often the yellowing and wilting of the leaves occurs on one side of the plant. The second side of cyclamen may continue to grow, but good flowering it is difficult to wait from such a plant. The fungus enters the plant through young roots and spreads through the tuber. Affected tissues are destroyed; the general appearance of the plant deteriorates. On the section of the tuber, the affected vascular bundles are visible.
Control measures: watering plants under the root with foundationazole (0.1%), spraying the above-ground mass with topsin-M (0.1%).

wet rot

This is a very dangerous bacterial disease. Caused by the pathogen Erwinia.
Symptoms: the disease begins with the fact that the plant suddenly withers, the leaves and peduncles hang from the pot, an unpleasant putrefactive odor appears from the infected tuber. Cyclamen roots also begin to rot. The bacterium enters the plant through cracks and wounds on the tuber or vegetative organs. Often, cyclamen infection occurs in places where leaves or peduncles are torn off. The source of infection is contaminated water or a diseased plant. The appearance of the disease is facilitated by warm and humid weather in summer when cyclamens are kept in the garden, on the balcony, on the loggia.
Control measures: does not exist, cyclamen must be destroyed in order to prevent disease of other plants.

Gray rot

The fungus Botrytis cinerea infects plants that are weakened due to poor location, it is especially dangerous in damp and cold air. The spores of the fungus are spread by wind and water. Infection occurs at high humidity, high density of cyclamens and cold night content. Contributes to the development of this disease in the plant improper watering, water ingress into the "growth point" of leaves and buds.
Symptoms: gray mold appears on the leaves and stems of cyclamen, which takes off with strong air movement; the affected parts of the plant darken and die. Flower stalks are especially susceptible to this disease. Cyclamen leaves turn yellow and die.
Control measures: Carefully remove the affected parts of the plant. Ventilate the room, but avoid drafts. Spray cyclamen less often, water less (better - in the morning, so that the soil has time to dry out during the day). The diseased plant is treated with a systemic fungicide.

root rot

Root rots are caused by various fungi (Rhizoctonia solani, Ramularia cyclaminicola); pathogens live in the soil. The disease occurs when cyclamen is planted in the usual garden soil which has not been steamed. The disease often attacks young cyclamens, slowing down their growth.
Symptoms: dark non-viable areas appear on the roots of young and adult cyclamen. Symptoms appear on the leaves as if they lack chlorophyll: the leaves turn pale, as they lack nutrition due to damaged roots.
Control measures: Use only sterilized soil for planting cyclamen. If cyclamen is sick, try shedding the ground with a systemic fungicide. But this measure is not always effective; most likely, it will not be possible to save a young cyclamen. You may have to part ways with your pet. You can try to save an adult cyclamen. It must be removed from the pot, washed and the damaged roots removed, then treated with a fungicide and planted in a steamed earthen mixture.

Anthracnose

Caused by a fungus of the genus Gloeosporium. This is a soil fungus that harms cyclamens during flowering. The disease develops in warm and humid conditions.
Symptoms: the growth zone of leaves and peduncles is affected. The disease may go unnoticed for some time until cyclamen releases flower stalks. Affected peduncles stop developing, look distorted, top part flower stalks seem to dry up. Flowering does not occur, as flower stalks do not develop. From contact with infected peduncles, infection of the leaves occurs. Young leaves dry up and curl around the edges, old leaves dry up and die.
Control measures: use steamed earth to prevent disease. When symptoms appear, try to keep the humidity levels relatively low. Remove damaged flower stalks and leaves. Treat the diseased plant with fungicides 2 to 3 times.

sooty fungus

The black fungus appears on the sweetish secretions that the aphid leaves on the leaves. An ugly-looking fungus plaque in itself is not dangerous for the plant, but it clogs the stomata and closes the surface of the leaf from light, as a result of which growth slows down and the plant weakens. Affected leaves dry out over time if not taken necessary measures.
Control measures: soot deposits are washed off with a wet cloth moistened with a 2% solution of green soap, followed by treatment with a copper-soap solution, then the plant is washed with clean warm water. You can treat cyclamen with a fungicide.

Disease control agents indoor plants

Initially, this flower existed only as an ordinary perennial herbaceous plant. But after some period of time, the life of cyclamen was adapted to home conditions and made it a houseplant.

On the this moment selection of cyclamen is well developed high level. If initially there were species only with white and red flowers, now you can find all shades of pink, and pale lilac, and pale purple. Distinctive feature of this plant is its flowering in winter period: October to March.

Common causes of ailments

There are quite a few reasons why a flower begins to overcome ailments. Among them are the most basic:

• in the room where the cyclamen is located, the air is not suitable, or rather it is not sufficiently humidified;
• the soil in the flowerpot is moistened too often and abundantly (how?);
• the air temperature in the room exceeds the norm - 17-20 degrees above zero;
• soil composition is incorrectly selected;
• proper care during the dormant period is not provided (there should be moderate watering, low lighting and minimal top dressing);
• during the period of active growth and flowering, there is not enough lighting.

Sometimes it’s not worth worrying about what to do if leaves and flowers have fallen from a plant. because after the cyclamen has faded, it begins to prepare for a dormant period and discards all "extra". Determining this dormant period is very simple: the plant bloomed safely from September to March and dropped the flowers.

But if the dropping of leaves occurs in the middle of flowering, then it is worth reconsidering the flower care points:

• lighting- there should be a lot of it, but at the same time you need to ensure that direct sunlight does not fall on the leaves;
• temperature regime- the air should warm up to a maximum of twenty degrees, but at the same time the temperature should not fall below ten degrees above zero;
• humidified air- but to maintain this condition, experts do not advise spraying cyclamen, best solution will put a container of water near the flower pot;
• hygiene- it is necessary to periodically wipe the leaves from dust, and also to remove dead areas in a timely manner.

Silver plaque or gray rot

This disease is caused by the fungus Botrytis cinerea. Usually, these fungi enter plants through polluted air or water. But if normal conditions for growing cyclamen are provided, this harmful fungus will not be able to develop and will simply die.

However, when creating conditions for the development of Botrytis cinerea ( high humidity air; low temperature, especially at night; excessively abundant soil moisture; improper watering, in which water enters the growth points of leaves or buds), the flower may die, and in a very short span time.

Symptoms of gray mold infection:

• the appearance of a silvery coating on shoots and leaf plates;
• affected flower arrows begin to darken and eventually die off;
• leaves on which mold has appeared, gradually acquire yellow, and eventually disappear altogether.

Gray mold treatment:

1. isolate the affected plant in order to prevent infection of neighboring flowers;
2. remove already "sick" areas of cyclamen;
3. ensure regular ventilation of the room, but this must be done in such a way that drafts do not form;
4. reduce watering to a minimum, and completely exclude spraying from care points;
5. treat the plant with fungicides (this can be Euparen, Rovral, Ronilan).

Reference! If the disease is not detected in time, the flower is unlikely to be saved.

Fusarium

Another name is dry rot. The reason for the defeat of the plant by this disease is also a fungus called Fusarium. The advantage of this flower ailment is that it develops rather slowly. And if you regularly inspect the flower, then there is every chance that cyclamen will be resuscitated.

The fungus destroys the tissues of the flower, and then passes to the vascular system, clogging the vessels of the plant. All this leads to gradual fading cyclamen.

Symptoms of the disease:

• turn yellow sheet plates starting from the top of the plant;
• in this case, only one side is most often affected, while the second continues its development and flowering.

Fusarium treatment:

1. isolate the flowerpot with cyclamen;
2. spray with a solution of "Topsin-M";
3. water the soil with a solution of foundationazole.

Important! Very often, the Fusarium fungus remains in the ground, so it is better to replace it with a new one or process the old one. This can be done by placing the soil in the microwave for a few minutes or a few hours in freezer.

wet rot

The causative agents of this disease are Erwinia bacteria. Cyclamen can become infected in several ways:

1. through standing next to flower;
2. through contaminated water;
3. through mechanical damage to different parts of the plant.

Symptoms:

• sharp wilting of leaves and flowers;
• an unpleasant odor that comes from the rhizome;
• root rot.

There is still no really helping way to cure a plant from wet rot. Therefore, the only right decision will destroy the flower along with the soil in which it grew, so that the bacteria do not spread to other plants.

Anthracnose

Caused by a fungus of the genus Gloeosporium. But the following incorrect points of care are already developing anthracnose:

• too much heat air (over 20 degrees of heat);
• too humid air.

For a very long time, this ailment may not make itself felt. Anthracnose appears only when a flower arrow is released on the plant. It grows in a curved shape, develops poorly, and then begins to turn yellow from the top. The buds never grow and even the existing ones eventually do not bloom. Then the disease passes to the leaf plates, which also turn yellow and dry. This also applies to young leaves.

Treatment:

1. isolate the plant
2. normalize the level of humidity in the room - it should be slightly lowered;
3. remove dried sections of cyclamen;
4. treat with fungicidal preparations three to four times with a break of 5-7 days.

Rhizoctonia

Rhizoctonia rot is caused by the fungus Rhizoctonia solani J.G. Kuhn. Both flowers and already formed ones can be influenced. cyclamens. Infecting fungi are localized in the soil and from there affect the root system.

Good conditions for breeding bending are:

• high air temperature;
• too humid air;
• overly active fertilizing.

Symptoms:

• the appearance of sagging dark pigmentation both on the ground part and on the underground part of the flower (this pigmentation tends to multiply very quickly);
• in places of pigmentation, a fungal plaque is formed, which can be white or gray.

Treatment:

1. to prevent the appearance of rhizoctoniosis rot, it should be given Special attention the choice of soil - it should allow the roots to "breathe" - and loosen the earth as often as possible;
2. completely stop watering;
3. replace the soil with a new one;
4. treat cyclamen with fungicides (spraying).

Attention! Rhizoctonia rot spreads very quickly and kills the plant at the same pace, so you need to act immediately.

late blight

Excited by the fungus Phytophthora. Favorable conditions for the development of this fungus are absolutely identical to those conditions that provoke the development of rhizoctonia rot, so we will not list them.

Symptoms:

• sheet plates lose their strength and stiffness;
• the lower leaves and, followed by other parts of the plant;
• the root tuber is covered with rot.

Treatment:

1. do not forget about the importance of soil quality: it must provide air circulation;
2. temporarily stop soil moisture;
3. get rid of the infected substrate;
4. treat the affected plant with the following fungicides: Profit Gold, Ridomil, Previkur.

Fusarium leaf wilt

The disease is caused by the fungus Fusarium oxysporum Schlecht. It is this mushroom that feels great in very dry soils that lack nutrients.

Important! Sharp changes in soil dryness and moisture cause the active development of the fungus Fusarium oxysporum Schlecht.

Symptoms:

• yellowing and drying of the lower leaves of cyclamen;
• damage to the root system;
• then flower shoots are susceptible to infection.

Treatment. Fusarium wilt is very difficult to treat.. In most cases, even fungicides do not help in the fight against this disease. Therefore, it is necessary to carry out preventive measures: carefully choose the soil, avoid elevated temperatures and sudden changes in soil moisture levels.

What to do for prevention?

Of course, any disease is best prevented than treated later. Therefore, it is worth mentioning separately the measures for the prevention of cyclamen ailments.

• First of all, you need to ensure that all points are observed. proper cultivation plants mentioned above.
• It is also necessary to regularly (at least once a week) carefully examine cyclamen for the presence of diseases and various attacks and respond to these changes in time.
• When a new “exhibit” appears in the collection of domestic plants, it must be sent to a monthly quarantine in order to be able to observe the development of the flower and eliminate ailments in time.

Conclusion

Judging by the reviews of amateur flower growers, as well as the conclusions of professional flower growers, cyclamen is a very difficult plant in terms of growing, requiring constant attention and continuous care. But the sophistication and originality that lurks in cyclamen is worth all the effort that you put into growing a flower. And then the plant will thank you for all the efforts with its stormy and long flowering to the delight of others.

One of the most common cyclamen diseases is Fusarium wilt. It represents fungal disease, which is caused by the fungus Fusarium. The impact of this fungus leads to damage to the tissues and vascular system of the plant. This disease has several names, including: “dry rot”, “core rot”, “shrinkage”. In the process of fusarium wilt, the defeat and death of cyclamen occurs due to a sharp violation of the vital functions of the plant, which occurs due to blockage of the vessels by the mycelium of the fungus, which releases toxic substances. The fungus persists for a long time in the soil and organic residues. From there, it penetrates the lower part of the stem and the root system of the plant.

Symptoms of the disease are as follows: starting from the tips of the leaves, the plant begins to turn yellow. Often, wilting and yellowing of the leaves occurs on one side of the plant. On the other side of the cyclamen, growth may continue. However, you will not expect normal flowering from such a plant. The fungus penetrates the structure of cyclamen through the roots, further spreading through the tuber. Then there is the destruction of the affected tissues, deterioration appearance plants. If you cut the tuber, then the affected vascular bundles will be visible.

As control measures, watering the plants with a solution of foundationazole, as well as spraying the stems and leaves with a solution of topsin-M (0.1%) is used.

Another dangerous disease is wet rot. Its causative agent is the bacterium Erwinia. Symptoms of the disease are that the plant suddenly withers, and the flowers and leaves begin to hang from the pot. At the same time, the plant exudes an unpleasant odor due to the fact that the roots of the plant also begin to rot. The bacterium enters the structure of the plant through wounds and cracks in the vegetative organs and tubers. The source of this infection can be a nearby diseased plant or contaminated water used for irrigation. Keeping plants in warm, humid conditions can contribute to the appearance of the disease.

Among the most dangerous diseases can also be called gray rot, the causative agent of which is the fungus Botrytis Cinerea. It affects mainly weakened plants. The spread of spores of the fungus occurs with water and wind. The defeat of plants occurs in conditions of cold night maintenance and high humidity.

Cyclamen, diseases and pests. One of the most common diseases of cyclamen is fusarium wilt. It is a fungal disease caused by a fungus. Fusarium. The impact of this fungus leads to damage to the tissues and vascular system of the plant.

This disease has several names, including: “dry rot”, “core rot”, “shrinkage”. In the process of fusarium wilt, the defeat and death of cyclamen occurs due to a sharp violation of the vital functions of the plant, which occurs due to blockage of the vessels by the mycelium of the fungus, which releases toxic substances. The fungus persists for a long time in the soil and organic residues. From there, it penetrates the lower part of the stem and the root system of the plant.

Fusarium wilt symptoms

Starting from the tips of the leaves, the plant begins to turn yellow. Often, wilting and yellowing of the leaves occurs on one side of the plant. On the other side of the cyclamen, growth may continue. However, you will not expect normal flowering from such a plant. The fungus penetrates the structure of cyclamen through the roots, further spreading through the tuber. Then there is the destruction of the affected tissues, the deterioration of the appearance of the plant. If you cut the tuber, then the affected vascular bundles will be visible.

Fight and treatment

Watering the plants with a solution is used as a control measure. fundazol, as well as spraying the stems and leaves with a solution topsin-M (0,1%).

Wet rot is another dangerous disease.

Its causative agent is a bacterium Erwinia. Symptoms of the disease are that the plant suddenly withers, and the flowers and leaves begin to hang from the pot. At the same time, the plant exudes an unpleasant odor due to the fact that the roots of the plant also begin to rot. The bacterium penetrates the structure of the plant through wounds and cracks in the vegetative organs and tubers.

The source of this infection can be a nearby diseased plant or contaminated water used for irrigation. Keeping plants in warm, humid conditions can contribute to the appearance of the disease.

Wet rot control

Unfortunately, there are no measures to combat this disease. The plant must be destroyed to avoid infection of neighboring cyclamen.

Gray rot - another variety

Among the most dangerous diseases can also be called gray rot, the causative agent of which is a fungus. Botrytis cinerea. It affects mainly weakened plants. The spread of spores of the fungus occurs with water and wind. The defeat of plants occurs in conditions of cold night maintenance and high humidity.

Symptoms of the disease are the formation of gray mold on the leaves of plants. Affected leaves and stems turn black and fall off.

As control measures, the removal of the affected parts of the plant, treatment with a systemic fungicide is used.

As you can see, the disease cyclamen can simply collect. Therefore, monitor the condition of your pet and try to prevent all these troubles.

In such cases, the plant stops active growth, covered with brown or yellow spots, deforms, weakens, dies.

In the first place, the leaves may turn yellow or become stained due to a violation of the system. Yellow and twisted leaves mean that there is little water for the plant, and if they begin to rot and dry out, then watering should be done a little more modestly or less often, analyze it.

The next common problem is gray rot and the cause of its occurrence is a fungus. By the way, this problem extends not only to the leaves, but to the whole plant. She, as a result, acquires a brown color, becomes covered with bloom, dies. In order to protect your plant from this trouble, you should monitor watering, ventilate the room and steam the soil before use.

Wet rot makes itself felt bad smell, plaque on the leaves and hanging leaves. Most often, the causes of such a problem are the use of unsuitable water or the infection of some plants by others. The biggest trouble is that this problem is not treatable and the only option to change something for the better is to instantly take the plant away from others and destroy it.

Cyclamen flower diseases

Sometimes the presence of pathogenic bacteria or fungus can only be known when flowers appear on the plant, although they appear in such cases for a very short time. The most common such problem is cyclamen anthracnose. Favorable conditions for its development is moist air, moist soil and high air temperature. This disease cannot be identified until the plant grows into flower stalks, which immediately begin to distort, their upper part dries out. Peduncles suffer so much that their flowering never occurs. If the necessary measures are not taken, the disease passes to the leaves, which begin to curl and die. Subsequently, the entire plant dies.

To protect your flower from such a nuisance, it is worth monitoring the watering and the state of the air, be sure to steam the ground before planting. If the disease has already been detected, then at least four applications of the fungicide should resolve the situation.

Pests of cyclamen and methods of dealing with them

Pests that often destroy cyclamens are aphids, thrips, and cyclamen mites.

Thrips are very active and very bright, so it is absolutely easy to identify them. In addition, they leave silvery traces of their movements. These spots inhibit the growth of the leaves of the plant, which can fall off if the necessary measures are not taken and the thrips lay new larvae. For the withdrawal of thrips, there are special tape traps and insecticides.

And one more thing that you have to deal with is the cyclamen mite. It is extremely small, it is impossible to see it with the naked eye. The affected area is inner part leaf, so it may seem that it is just dust, however, if it does not climb so easily, then you should pay attention to the edges of the leaves, if they are curled. If so, then the affected leaves should be removed immediately, and the plant should be treated with chemical antiseptics.
