Healthy and well-groomed indoor flowers always please with their appearance, but even minor mistakes in caring for plants can lead to the development of fungal and other diseases. In this article we will try to understand in detail where anthurium diseases come from.
Often, improper care can cause houseplant diseases.
Anthurium is a houseplant of the Araceae family, a close relative of Monstera, Dieffenbachia, Spathiphyllum and Zamioculcas. In indoor culture, Anthurium Andre and Scherzer are grown more often than other species.
Usually these spectacular plants differ good growth, they adapt perfectly to the conditions of the rooms, but sometimes, for no apparent reason, the plants begin to hurt. It is impossible to say that this is nonsense - after all, anthuriums, deprived of their usual living conditions, are subject to stress, like others houseplants Therefore, it is very important to strictly observe the requirements of agricultural technology when growing home flowers.
Under what conditions does anthurium feel great?
Lighting
The flamingo flower requires bright, diffused lighting, so the plant does not feel comfortable on southern and northern windows. in the best possible way. The bright sun burns the leaves; it is too dark on the northern windowsill for buds to form.
Temperature
In summer, the suitable temperature for anthuriums is from +20 to +28C. With the onset of autumn, flowers are kept at lower temperatures. During this period, plants need around +15-16C, and for Scherzer’s anthurium, a cooler maintenance regime is established - flower buds are formed only when the room temperature drops to +12-16ºC.
From mid-January, the temperature of the plants is gradually increased, bringing it to + 20-22C.
Air humidity
The tips of the leaves can dry out for many reasons.
Anthuriums are inhabitants of the tropics, so they are accustomed to high air humidity. IN room conditions have an effect on plants Negative influence dry air and drafts. Plants require additional care: daily spraying with warm soft water, placing aerial roots in moistened moss, bathing in the shower, and measures to humidify the air in the room where exotic plants grow.
In winter, when it works central heating, the air in the rooms becomes very dry. To make anthuriums feel good, it is worth equipping radiators with air humidifiers. Pots with indoor anthuriums can be placed on a large tray with wet expanded clay. It is useful to humidify the air around the flowers several times a day using a spray bottle, being careful not to get water on the flowers.
Watering
Anthurium loves high humidity, but disappears very quickly if the soil in the pot is waterlogged. Between waterings, it is useful to dry the substrate by about ½ the volume of the pot. Water for irrigation is well protected; it is even better to water the anthurium with water from a filter. During the formation of flower buds, watering is reduced.
Top dressing
Anthuriums - flower diseases are associated with improper care. Overdose of fertilizers is one of the possible errors flower growers who forgot that the plant does not tolerate high concentrations of minerals.
Fertilize the plant during the period of active growth approximately once a month, while the nutrient solution for feeding is prepared in half concentration. It is best to use special fertilizers for Aroids to feed plants.
The soil
Too heavy soil in an anthurium pot can also cause plant disease. The ideal soil for planting anthuriums should have a slightly acidic reaction (pH 5-6). The soil should not cake or compact - the roots are strongly compressed in such a substrate. Best cast soil for growing anthurium:
- Peat – 2 hours.
- Finely chopped sphagnum moss – 2 tsp.
- Leaf soil - 1 tsp.
- Pine bark or coconut fiber – 1 tsp.
Unbalanced soil and other errors in anthurium maintenance can cause stress and disease to the plant.
How to determine the cause
Yellow and dry spots on the leaves are a sign of a developing disease.
Diseases of indoor anthuriums can be roughly divided as follows:
- Non-compliance agrotechnical techniques by flower content.
- Diseases caused by infections.
- Damage caused by insects.
Let's take a closer look at each point.
Failure to comply with agricultural technology rules
Leaves on plants that are kept in improper conditions turn yellow and dry out.
These non-infectious diseases can greatly undermine the health of a houseplant, and they arise only from improper care.
- Flowers do not appear for a long time - thus, the plant signals problems in care. In order for buds to appear on anthurium, the plant must be kept at a temperature of at least 18C, at complete absence drafts, and also protect the flower from scorching sun rays. The soil should easily allow water to pass through; the pot must have a drainage layer. Treatment: bring the conditions of maintenance into compliance, feed the plant with mineral fertilizers.
- Leaves dry out - due to insufficient watering and low room temperature, leaves can actually dry out. Plants must be periodically examined to determine the causes of diseases; sometimes such symptoms are characteristic of infections, which require certain treatment. Treatment for non-infectious causes: streamline the care of your pet.
- Chlorosis - yellowing of anthurium leaves indicates unbalanced watering with hard chlorinated water, untimely (or excessive) application of fertilizers, draft, lack of drainage, long-term keeping of a pot with a plant in a pan of water. Treatment: normalize the regime of keeping the flower indoors.
- The appearance of dry spots on the leaves is possible when anthurium is kept in a sunny window. Burns on the leaves of the flower cannot be treated.
- Plant pox is characterized by the appearance of swollen areas on the leaves; the disease begins when the plant is not maintained correctly (severe cooling, a significant drop in temperature, high humidity). Treatment: streamline care.
- Enation - with this little-studied disease, deformation of anthurium leaves occurs. Treatment: normalize plant care.
Diseases caused by infections
Infectious diseases are the most dangerous.
Septoria
The disease is caused by the fungus Septoria, which spreads quickly in warm and humid environments. Appear on the leaves of the flower brown spots with a characteristic yellow rim. Gradually the leaf dries out, and the spores infect other parts of the plant.
Treatment: treatment with copper-containing fungicides. The soil is treated with Abiga-Pik.
Anthracosis
It is characterized by the appearance on anthurium leaves of dried brown spots with black dots (spores), the diameter of which can range from 2 to 12 mm. The disease progresses with high humidity and temperatures from +23 to 27C, these are exactly the conditions that are vital for an indoor flower. The disease is caused by the fungus Colletotrichum orbiculare.
Treatment: treatment of anthurium with Previkur, Fitosporin, Abiga-Pik, Acrobat MC, Fundazol, Ridomil Gold MC, Skor, be sure to follow the instructions for use. Feed with phosphorus-potassium fertilizers.
Fusarium wilt
The leaves on the plant turn yellow and wither en masse, and a white-pink coating appears on the root collar. When watering, infection of plant parts only increases. Contribute to the spread of infection heat and humidity.
Treatment: repeated treatments with fungicides.
Rust
Characteristic rust-colored rashes appear on the underside of the leaves; the upper part of the leaf in the area of infection becomes lighter. The spots quickly merge, covering the entire leaf, which eventually dries out.
Powdery mildew
The leaves of the flower turn yellow and become smaller, the internodes become shorter, and on the underside of the leaf blade, spores similar to a powdery coating are clearly visible. The leaves very soon dry out and fall off.
Treatment: use of systemic fungicides.
Bronzing virus
Carried by thrips. Symptoms of the disease: partial discoloration of leaves, the appearance of wrinkles and small holes on the leaf blades.
Anthurium diseases caused by viruses cannot be treated; the plant is destroyed.
Damage caused by insects
This is what a scale insect looks like.
Indoor anthurium is greatly weakened by pests that can settle on the leaves and stems of the flower: scale insects, spider mite and mealybug. By sucking the juices of the plant, these pests can provoke the development of diseases on the weakened flower.
Treatment: use of systemic insecticides.
May occur during natural aging. In this case, the color of one or two lower leaves changes. These gradually dry out and fall off. To improve appearance, It is recommended to rejuvenate the anthurium.
If the plant is young, and the leaves are already turning the color of straw - it is quite possible that the flower is receiving too much light. To fix the problem, just move the pot to a less lit place.
The color becomes pale with a yellowish tint and with a lack of sun, if the flamingo stands far from the window. You can equip the place with additional lighting or simply move the flower to the windowsill of the western or eastern window.
Drying
Drying leaves are a sign of improper care.
The flamingo stands in a draft, is kept in constant coolness, and lacks moisture in the soil or external environment.
Appearance of spots
- Large spilled brown spots indicate frostbite.
- Beige dry specks are evidence of the activity of the sun's rays, which caused burns. Shading or changing the location will save the plant from further damage.
- Stains different diameters covering any part of the leaf surface may indicate a pest invasion, especially when growth stops at the same time. If the new leaves become excessively large in size, and any marks form on the more mature ones, then we are talking about an excess of fertilizers in the soil.
Why do the tips of Anthurium leaves dry out?
The most obvious reason— the air in the room is always dry, from which the plant suffers. You can increase the humidity by regular spraying and installing a tray filled with wet stones such as pebbles or expanded clay.
Have you followed all the recommendations, but the edges are still drying out? This means that the roots of the delicate epiphyte do not receive oxygen. The soil should be changed by adding loosening components such as pieces of brick, charcoal, pine and fir cones, perlite.
The flower is drying
Usually this is a sign of physiological aging of the inflorescence; it dries up and forms a fruit. Also, the cause may be excessive dryness of the soil and air, excess light and sunburn.
The leaves of the flower turn black. Male happiness
This problem occurs when the calcium content in the soil is high. The soil must be changed to fresh, high-quality soil and the application of fertilizers must be reduced in the future.
Flowers turn black
Black or chestnut marks unexpectedly appear on the bedspread only in one case - when spraying, water got on the inflorescence.
Anthurium really doesn’t like this! Pick off any damaged flowers and remember the lesson so you don't repeat the same mistake again.
The leaves are curling
In this way, the tropical resident is protected from unfavorable conditions external environment, namely:
- drafts
- lack of light
- direct rays of the sun
- arid air.
Wilting foliage
Loss of turgor occurs due to rotting of the root system.
If the plant is watered too often, without waiting for the soil to dry out, root rot will certainly attack. Then the leaves lose their elasticity, wither and droop.
Urgent resuscitation of a sick flower is required. It is removed from the soil, the roots are washed in warm water to completely free from dirt and carefully inspect. All affected parts are cut off and the remaining parts are dried. in the air for at least 30 minutes. During this time, the soil is completely replaced with fresh one, and the pot is disinfected in a strong solution of potassium permanganate.
Flower diseases male happiness
Smallpox
The disease is non-infectious, caused by errors in. The decorative surface of the leaf is covered with convex plaques, swellings and marsh-colored rings. Smallpox becomes a provocateur cold air indoors, especially against a background of high humidity; any root damage or deficiency nutrients.
Enatsii
Presumably the disease occurs due to sudden changes in temperature and humidity. There is a loss of decorativeness of the leaves; they become deformed, develop unevenly and become covered with convex growths of a rounded shape.
Stem rot
A fungal disease that appears when there is high humidity in both the surrounding air and the soil. Externally it is manifested by the formation of dark watery marks on the shoots and the death of stems. Characteristic sign - small sporangia in the affected areas, at the initial stage they are white, then darken.
The plant is quarantined, the affected parts are cut off and treated with fungicides, for example, Rovral, Fitosporin, copper sulfate. If treatment does not help, the flamingos are disposed of.
Anthurium pests
Aphid
A small pest that multiplies quickly, forming large colonies. It feeds on plant sap by piercing tissues. Sits on inside leaves, so it is not immediately detected. Usually it is not insects that are noticed, but the consequences of their activity - curled leaves, dried parts, slowed growth.
Various are used to fight insecticides, both biological and chemical in nature— Fitoverm, Actellik, Karate, Intavir, Decis. Among the folk remedies, infusions of onion and garlic help.
Scale insects - real and false
If oval convex tubercles of brown or beige color begin to appear on the leaves, which can be picked off with a needle or toothpick, This means that the anthurium was attacked by scale insects. These are small sucking pests, reliably protected by a dense shell. They suck out the juices, inhibiting the development of the affected flower.
Contact insecticides will not help; scale insects are destroyed using systemic drugs - Confidor, Bankol, Biotlin.
Their active substances penetrate inside the plant and poison the juice, which subsequently enters the body of pests and kills them.
Spider mite
Microscopic pests, completely invisible to the eye. However, they cause quite a lot of damage. By feeding on plant sap, ticks greatly inhibit the further development of the victim, often leading to its death. They settle where dry air and warmth prevail. Distinctive feature presence of mites- thin cobwebs clinging to the ground parts of the anthurium. In addition, the surface of the leaves is covered with pinholes that are light yellow in color.
Acaricides are used against ticks - Actellik, Flumite, Oberon, Akarin, Omite.
Thrips
Inconspicuous sucking insects that look like small flies. They feed on sap, infecting their victims with viruses and polluting them with secretions, which the sooty fungus likes to attack. Their presence is revealed by the strange coloring of the leaf surface, which takes on an unpleasant yellowish-white color.
They are used against them sticky traps and various preparations— Fitoverm, Karate, Molniya, Actellik, Intavir.
Whiteflies - tobacco and greenhouse
Small cute butterflies with delicate wings, as if sprinkled with starch. At the slightest movement, they fly up from their favorite plant and scatter in different directions, so it is not difficult to detect them.
Used to get rid of insects insecticides, for example, Fufanon, Biotlin, Tanrek, Iskra, Bison.
Why did Anthurium's leaves become small and growth stop?
In this simple way, exotics report a lack of nutrients. This may be insufficient lighting, deficiency mineral fertilizers or soil with a neutral or alkaline reaction. The absorption of nutrient compounds occurs only in the presence of acidic soil, the only one suitable for the flamingo flower.
Anthurium is a rather complex and capricious plant.. It is susceptible to attack by many pests and diseases, is sensitive to any care errors and takes revenge on its owner for inattention. Therefore, it is recommended to start it only for experienced flower growers who have enough time and desire to deal with their acquisition.

Next you will see photos of Anthurium leaf diseases and pests and their treatment at home: 
Keep an eye on this and do not leave the anthurium in drafts during ventilation. It is better to initially place it in a place where, when opening the windows, gusts of wind from the street will not hit the plant.
Unsuitable room temperature
Being a heat-loving tropical plant, anthurium tolerates summer temperatures up to +28°, if it is not exposed to direct sunlight. It tolerates cold much worse.
When the air temperature drops, the leaves of Male Happiness become covered with black spots, after which the plant dies quite quickly.
Anthurium should not be allowed to stay in a room with an air temperature below +16° for a long time., even in winter it should be higher for this heat-loving flower.
The owner of the anthurium needs to carefully monitor temperature conditions and the absence of drafts in the room.
Important! The critical temperature for the well-being of the plant is +16°.
Calcium salts in the soil
If a suitable microclimate has been created for anthurium, but the leaves still turn black, the reason lies in unsuitable soil. It must be replaced with a substrate for aroids, which can be bought at a gardening store or ordered online.
Also you can make a mixture of chopped moss, peat and turf soil (2:2:1). A mixture of equal proportions of peat, sand and leaf soil, you need to add a small amount of charcoal or pine bark to it. At 1/3 of the height of the pot, you need to lay out drainage, for example, from expanded clay.
Shields
These are tiny insects that can live on anthurium leaves. Because of them, small black spots appear in the form of dots.
- You need to carefully examine the plant; if insects are found, it should be removed away from other indoor flowers.
- Scale insects are removed manually cotton swab, soaked in an insecticide solution.
- After this, wipe the leaves with a cloth soaked in soap solution with the addition of kerosene.
It is unlikely that you will be able to notice all the scale insects at one time., you need to re-inspect the leaves and stems for several days.
Why does the plant become covered with yellow specks?
Excess moisture in the soil
Do not turn the soil in the pot into non-drying mud. There is no need to wait for the soil to dry completely; you need to water it when its top layer has dried, but adequately and little by little.
Important! You cannot leave water in the pan; it must be drained immediately.
If there is high air humidity in the room, for example, the anthurium is located next to a huge aquarium, you need to water even less often; the soil in the pot will remain moist for a long time.
Chlorine in irrigation water
Do not water with water that has been in the refrigerator, because low temperature water can harm the root system of this delicate flower.
If it is not possible to water with filtered water, tap water should be collected in a wide container, for example, a bucket, and left open in the room for a day so that the excess chlorine disappears and the water itself becomes warm.
Pot too small
The problem is solved by transplanting into a suitable pot. In the new one, there should be 2-3 cm from the walls to the root.
Attention! Anthurium needs a narrow, high pot. Ceramic ones are not suitable, the best option is plastic ones.
Excess fertilizer
In spring and summer, it is necessary to feed no more than once every 2-3 weeks with azophoska at a concentration of 1 g/l with the addition of potassium humate in an amount of 200-300 mg/l. Organic fertilizers feed no more than once a month.
Lack of light
Anthurium does not like the scorching rays of the sun, but it is also too far from the window in its shade. The best option– western and eastern windows or place it on a table next to a south window.
Natural aging
If all the leaves are green and healthy, new young ones are growing, the plant is provided with proper care, but one or more lower leaves have turned yellow, they need to be cut off. This is a natural process, no need to worry about it.
Causes of dry spots
Excessive air dryness
You should regularly spray water around the plant from a spray bottle or install a humidifier.
Insufficient watering
Anthurium does not like excessive soil moisture, but The earthen ball should not be allowed to dry out completely. The plant will tolerate this especially poorly if it remains in dry soil for several days.
If you want the plant to remain healthy, be sure to ensure regular and moderate watering.
The owner of the plant should also remember that anthurium is very sensitive to changes in humidity, so they must be smoothed out as much as possible when the heating is turned on.
Anthracnose
This is a fungal disease. The leaves begin to appear, and gradually the dry spots move to the center. All affected leaves must be cut off and the plant treated with a fungicide.
You can find out what other diseases, besides anthracnose, can threaten anthurium.
Aphid
All leaves below, above and stems are treated with a special preparation against aphids.

Here you can see what flowers with similar problems look like.
Foliage care
You need to regularly wipe the dust off the leaves with a damp cloth. A thick layer of dust should not be allowed to remain on the leaves for too long, as this will cause them to “suffocate.” When creating comfortable air humidity for the plant using a spray bottle, water should be sprayed nearby, but so as not to get on the leaves, otherwise, after drying, unsightly traces of drops will remain on them.
To keep anthurium leaves green and healthy, proper care is important. capricious plant, creating a suitable microclimate, as well as the correct watering and fertilizing regime.

Anthurium is beautiful and exotic, but when growing, you often have to deal with diseases of the capricious flower. Anthurium can become ill either from improper maintenance and care, or from various diseases; it is also attacked by pests. In this article we will look at all the most common ailments and diseases of anthurium and find out how to treat the plant.
general information
Anthurium or, as people say, “male happiness” is a tropical flower, heat-loving and delicate. The plant is very sensitive to external conditions, watering, fertilizing and other care. If you deviate from correct agricultural practices, you will soon notice that the flower is unwell.
If you see that the anthurium looks bad, is weakening, the leaves are turning yellow, suspicious spots appear on them, or other alarming symptoms are observed, you should inspect the flower as soon as possible.
Having identified a problem, you need to start eradicating it. In most cases, this requires normalizing living conditions and paying more attention to care. However, sometimes the anthurium gets sick quite seriously - then more effective measures have to be taken.
In total, there are three major factors that are the causes of anthurium disease:
- violation of agricultural practices and maintenance in unsuitable conditions;
- infectious diseases;
- pest damage.
Each of these factors hides many specific reasons that cause flower malaise in individual cases.
Violation of agricultural technology and conditions of detention
These reasons are the most common when cultivating an exotic beauty at home. Most often, it is because of improper care and maintenance that the flower begins to hurt. Fortunately, the situation in this case can be corrected quickly, the main thing is not to delay it.
No flowering
The problem is most often associated with violation of the conditions of detention. In much rarer cases - with infectious diseases. The following factors can cause the cessation of flowering:
- too cool external temperature (below +18 degrees);
- keeping the plant in drafts;
- exposure to direct sunlight;
- stagnation of water in the pot.
The last reason is the most common. Anthurium roots are very sensitive to soil moisture levels, and allowing the soil to become waterlogged is critical for the plant.
What to do
Flowering is caused in this case by eradicating the cause that gave rise to the absence of buds. In any case, additional feeding with complex minerals will not hurt.
Spots on leaves
Often, improper care leads to the appearance of unsightly spots on the leaves, slow growth, and changes in foliage color (see photo). Sometimes you can see spots Brown not only on the leaves, but also on the neck of the plant. The first step is to evaluate what kind of stains appeared:
What to do
The nature of the stains should be assessed and the cause of their appearance should be eliminated. But if the plant is flooded, it is recommended to transplant it into another pot with dry soil. Before replanting, trim off rotten roots.
The flower dries up
This usually happens due to insufficient soil moisture, less often because the air temperature is too low.
What to do
As in other similar cases, it is necessary to correct the situation by normalizing the conditions of keeping and caring for the plant. That is, water and place the flower in more warm room. Feeding won't hurt either.
Enatsii
This disease is expressed in the drying of the flower, deformation of the leaves, and the appearance of ugly growths on them (see photo). The disease is non-infectious in nature and why it appears is still unknown. However, it has been noticed that enation is more often observed after the anthurium has been exposed to sudden temperature changes.
What to do
You can cure a flower in this way: you should normalize the conditions of its maintenance and prevent strong temperature fluctuations. Gradually, the plant will return to normal, and unsightly defects in its appearance will disappear on their own. Don’t forget to feed the plant so that its immunity is always high.
Smallpox
Although this is a disease, as in the previous case, it is, however, non-infectious, non-contagious and occurs due to non-compliance with the rules of care and poor maintenance. The symptom is unsightly growths on the leaves of a convex shape (see photo).
What to do
The pot must be removed to a warmer place, protected from direct sun and drafts. Usually this is enough.
Other ailments
It happens that anthurium grows very poorly and develops poorly. The cause is usually a lack of nutrients. In this case, you need to either apply fertilizer or (if the soil is severely depleted) transplant the plant into a fresh substrate.
The leaves turn yellow and dry, and the root collar becomes brown and mold appears on it due to critical waterlogging of the flower. In this case, you cannot hesitate - urgent resuscitation measures are necessary. It is necessary to replant the anthurium and remove all damaged, rotten fragments.
Attention: after removing the affected parts, do not forget to sprinkle the cut areas with crushed coal or ash for disinfection and faster healing.
Infectious diseases of anthurium
Anthurium, due to its delicate constitution, suffers from infectious diseases quite often. But still less often than from violations of agricultural technology. You should not despair if the flower is struck by some kind of disease - thanks high level With modern fungicides and timely treatment, almost any situation can be corrected. Next, let's look at the most common diseases.
Anthracticosis and septoria
These are fungal diseases that most often affect anthurium. A symptom of both diseases are brown and reddish spots that appear on the leaves (see photo). The tips of the leaves may also turn black.
What to do
Watering for fungal diseases must be reduced, since it is often waterlogging that causes them. Treated with chemical fungicides. The composition of fungicides must include copper - it is this mineral that helps to quickly deal with the causative fungus. The soil also needs bactericidal treatment: Abiga-Pik is suitable for this purpose.
Affected parts should be removed and burned before processing. If the processing does not produce results, you will have to part with the flower: it is destroyed along with the soil. The pot may still be useful, but it needs to be thoroughly washed, treated with a disinfecting solution and thermally treated.
Gray rot
The disease is also fungal in nature and first affects the trunk of the plant, then the shoots, and lastly the leaves (see photo). The infection spreads very quickly, and as soon as possible the affected areas of the flower die.
What to do
It is necessary to get rid of rot immediately as soon as the first signs are noticed. Highly effective chemicals should be used - only they can be guaranteed to save the plant. Traditional medicines will not help in this case.
All affected fragments should be removed, followed by chemical treatment. There should be at least three such treatments - after short breaks. If the case is already advanced and treatment does not help, the flower is destroyed.
Fusarium
This fungal disease causes the anthurium foliage to wilt and fall off. The disease affects the roots of the plant, therefore it is extremely dangerous and often leads to the death of the flower. The first sign is a sudden and sharp wilting, wilting of the anthurium. Peduncles bend at an unnatural angle, the foliage suddenly and strongly turns yellow (see photo). With this disease, the fungus penetrates the plant tissue, clogging vital vessels.
What to do
A sick flower should be urgently isolated from other indoor plants. If the disease has not yet seriously affected the plant, you can try to cope with it with additional mineral supplements, increasing the immunity of anthurium.
And if the disease has not yet affected the root, you can try to cope with fusarium with the help of copper fungicide. Experienced flower growers use the following method:
- remove the plant from the soil, wash it off the ground;
- soak the roots in a solution of Fundazol (weak);
- cut off affected and rotten parts of the plant;
- transplant the anthurium into new soil and new pot.
If the treatment has no effect, the flower is destroyed.
If the roots are already affected, you can cut off the top of the flower and try to root it. Hold before placing in the ground bottom part tops in Fundazol solution for half an hour.
The best way to combat this dangerous disease- prevention and prevention in principle of its occurrence. When planting a flower, in order to prevent fusarium, it is recommended to add several granules of the drug Trichodermin to the soil. In addition, it is necessary to constantly take care of maintaining the health and high immunity of the plant.
Rust
This disease cannot be confused with another, since the symptom of rust is very characteristic brown-rusty spots on the leaves. The spots spoil the decorative appearance of the flower and gradually spread, becoming wider, the foliage then dries out and falls off. Look at the photo of anthurium leaves affected by rust.
What to do
Rust should be treated by treating the flower with chemical and alcohol fungicides. Treatment is carried out every 3-4 days for two weeks. Suitable medications include:
- Ordan;
- Topaz.
Fitosporin-M can be used as a preventative against rust.
With this disease, you cannot spray the plant, as fungal spores can quickly spread to healthy leaves. The treatment is carried out by wiping the leaves with a fungicidal solution.
Root rot
The disease usually occurs due to systematic waterlogging of the flower. The disease is dangerous as it can lead to the death of the plant.
What to do
The anthurium is removed from the pot, the roots are inspected and those affected by rot are cut off. The remaining healthy rhizomes are treated with Maxim or Fitosporin-M, and then transplanted into a new pot with dry soil. Do not forget to read the description of the drugs to choose the correct dose and proportions. You should not water the plant for some time after transplanting.
Powdery mildew
The disease usually occurs due to keeping the plant at low temperatures simultaneously with waterlogging.
What to do
If the flower is flooded, a transplant is required. In other cases, you can get by by moving the pot to a warm place and spraying with Acrobat and Topaz.
Pest infestation
Aphid
Since pests multiply very quickly, you need to get rid of them quickly. Fortunately, removing aphids is not difficult: you just need to buy a suitable insecticide and treat the plant. A day after treatment, the leaves should be washed with water to wash off dead and still living insects. And such washing of the leaves will protect against chemical burns.
Shchitovka
What to do
When the scale insects multiply, the insects can be seen with the naked eye: treatment should then be undertaken urgently. The flower must be isolated from other plants and washed with water.
Then an insecticidal treatment is carried out, a day after which the flower should be washed again. There should be two treatments in total. If the scale insect has not yet had time to reproduce, you can try to deal with it using a regular soap solution.
Mealybug
This pest is the easiest to deal with, since it can be noticed almost immediately. The scale insect covers the leaves with a whitish coating, which immediately catches the eye. However, if rescue measures are not taken quickly, the scale insect may even destroy the anthurium.
What to do
You can cope with the misfortune by washing the flower with a soap or alcohol solution. After treatment, you must also rinse clean water. To ensure a guaranteed result, the treatment is carried out in two stages: the second one a week after the first.
Whatever ailment happens to anthurium, useful general tips care and maintenance will come in handy in any case.
Humidity level
When growing a tropical flower, you should remember that high air humidity is a vital necessity for it. The humidity level should be 70-80%, if less, then only for a short period.
To ensure such humidity in our apartments, you will have to either spray the plant more often, or purchase a special humidifier, or place the flower on a tray with wet expanded clay. Last option least labor-intensive, and does not require any expenses.
Why spraying is not the best the best way out? Because water leaves whitish, unsightly spots on the leaves.
If the flower grows in a dry room, it will get sick more often and is more likely to be affected by spider mites. In addition, dry air leads to:
- drying and yellowing of foliage;
- in severe stages - to curling and blackening of leaves;
- drying of buds - both those that have blossomed and those that have not yet bloomed.
Air temperature
Since this plant is heat-loving, it must be kept at a temperature not lower than +18 degrees in summer and +16 degrees in winter. The best option and most suitable for the flower would be to keep it from May to September at a temperature of +25-28 degrees.
Drafts and cool wind blows are completely contraindicated for the plant. Under the influence of drafts, the roots of anthurium often rot, its flowers and leaves freeze. And spraying in winter followed by opening the window for ventilation is the most reliable way destroying a flower.
Lighting
Anthurium needs abundant lighting, which is important for its lush and long flowering. However, being under direct sun rays(especially at noon) the plant does not tolerate. In nature, it grows in the lower tiers of tropical forests, shaded from above by tall trees.
Place the flower in a place that is sufficiently lit but shaded. In winter, the anthurium will require additional lighting for normal functioning.
Watering and substrate features
The flower grows best in moist, permeable, loose soil. Watering should be done only with soft water without impurities of salts and bleach. If the air humidity is high, it is not worth watering often.
So, we found out what diseases and why anthurium suffers and found out how to cure the plant in each case. The main measure to combat disease is proper care of the plant and maintaining it in suitable conditions. By complying with the requirements of agricultural technology, you will greatly reduce the likelihood of flower disease. Well, if the plant does pick up an infection or pests, you shouldn’t hesitate with treatment: the sooner you start taking action, the greater the chances of success.
Anthurium is a perennial indoor plant that looks attractive regardless of the time of year. The flower is especially beautiful during flowering, when blankets of pink, white, purple and red colors appear on the plant. It cannot be said that the plant is capricious, but if not proper care may get sick. In the article we will consider the question: “ Anthurium disease, caused by viruses, infectious and non-infectious." We will try to understand the reasons for the yellowing of foliage and consider the question of how to avoid mistakes when growing anthurium at home.
Anthurium – evergreen. The tropics are considered the birthplace of the flower. Particularly beautiful during flowering. It is for the bizarre shape of the flowers that anthurium is called flamingo flowers.
The flower, a photo of which can be seen in our gallery, is popular both among ordinary amateur flower growers and among professional collectors. Homemade anthurium can be used for interior decoration; leaves and flowers are used to create compositions and elegant bouquets.
The flower is notable for the fact that it can stand in a vase for a long time when cut. However, there are many diseases to which this beautiful plant is susceptible.
Leaf diseases: description and causes, photos
Anthurium diseases can be not only fungal. There are also viral diseases, infectious and non-infectious. Treatment of a flower for diseases is impossible alone folk remedies. It is necessary to apply more fungicides. Such drugs as Fitosporin-M and Fundazol have proven themselves well.
Treatment with drugs should be carried out in well-ventilated areas or, in general, the plants should be taken outside.
Before processing, the flower pot is placed in a large plastic bag. After spraying, tie the bag and leave the plant in such a mini-greenhouse for 15 minutes. When time will pass, you should remove the anthurium from the bag, let it dry and return it to its original place.
After the first main treatment, 7 days should pass, then the treatment should be repeated. A third spraying is required, which is carried out a week after the second treatment.
Fungal diseases of flowers, causes and treatment of anthurium
Fungal diseases of anthurium include root and stem rot, fusarium, rust, septoria and powdery mildew. In the fight against diseases, fungicides and special preparations are used to combat diseases of indoor plants.
Root rot
Excessive watering, constant soil moisture, along with low air temperatures lead to a disease such as root rot. When the root system is damaged, the leaves become much lighter than usual, then turn yellow and wither.
If you remove the plant from the pot and examine its roots, you will see that they have lost turgor and become lethargic and soft. If you take a closer look, then, starting from the middle, the roots begin to separate and hang like “rags.”
If the disease is at an early stage, it is necessary to stop watering, remove the plant from the ground, allow the earthen coma to dry and replant it in new nutritious soil. It is important to monitor the humidity in the room.
If upon inspection of the plant it is discovered that the roots are severely damaged, it is necessary to cut off all damaged parts to healthy tissue. The cut areas must be sprinkled with crushed coal.
Attention! When planting in new soil, you must not forget about the drainage layer, which will not allow the roots to rot. Expanded clay can be used as drainage.
To water the plant, it is important to use water with Alirin-B or Fitosporin-M dissolved in it. When preparing the solution, the concentration described in the instructions must not be exceeded.
At an advanced stage, when the entire root system, the anthurium is unlikely to be saved, so it is better to destroy it so that the disease does not spread to other plants.
Stem rot
The disease may occur due to overwatering And constant maintenance soil moisture. A decisive factor is also the reduced room temperature.
At the beginning of the disease, vague watery spots, colored black, appear on the leaves. If no action is taken, the disease will begin to spread to other parts of the plant. The affected parts of the anthurium die off over time. If you look at the affected area more closely, that is, through a magnifying glass, you can see a huge number of sporangia. At first they are whitish, then they become black.
The sick person needs to be isolated indoor flower from other plants, cut off all damaged parts of the anthurium and treat the plant with a fungicide. It is necessary to carry out 2 treatments with phytosporin with an interval of 1 week between sprayings.
If the disease is advanced, it is possible that the plant can no longer be helped. You need to gain strength and throw away the flower. And inspect all other plants with which the anthurium grew for disease.
Infectious diseases
Among the diseases spread by infectious means, septoria and fusarium wilt can be distinguished. If the disease is detected too late, it is practically impossible to cure.
Septoria
The presence of the disease is indicated by brown spots on the leaves of plants. They usually have an irregular shape, with a border of brown or brown around the edges. yellow color. If you examine the spots through a magnifying glass, in the middle of them you can see small black dots - sporangia.
How to treat anthurium leaves from septoria?
If septoria is severely affected, you will have to tear off all the foliage and burn it. The air humidity in the room should be reduced. It is recommended to exclude plant care procedures such as spraying foliage.
The flower needs feeding with complex fertilizers for flowering plants. After inspection for pests, the anthurium must be treated with copper-containing preparations or sprayed with Fitosporin-M.
Fusarium wilt
A rather serious disease in which the foliage withers massively. First it turns yellow, then it dries out and falls off. If you examine the root collar, you will notice a white-pink coating. Infection spreads during watering, when the optimal air humidity does not correspond to the temperature.
Attention! Still not found effective way combating fusarium wilt. You can try spraying the green mass of the plant with fungicides and spraying the soil with pesticides. To save the plant, it is important to try all methods of control.
Treatment should be carried out three times at weekly intervals. A single treatment has never brought a positive result.
Rust
When the disease occurs, spots may be seen on the upper part of the leaf blade. irregular shape, painted light yellow, and on the underside of the leaf there are brown spots and pustules. As the disease develops, the spots spread throughout the entire leaf, the plate withers and dries out. Treatment is carried out using fungicides.
Powdery mildew
It would seem that the plant likes everything, it smells fragrant and pleases the eye, and suddenly an incomprehensible leaf fall begins. What is the reason , Why did the plant's leaves begin to turn yellow and dry? About defeat powdery mildew evidence of plaque white, which spreads throughout the entire green mass of the plant. Treatment with Topaz gives good results.
Viral diseases
Among the viruses that affect anthurium is the bronze virus.
Bronzing virus
An unpleasant disease that manifests itself as discoloration of plant foliage. With the armed eye, you can notice pronounced wrinkles and small through dots on the surface of the sheet.
The virus is spread by insects, such as thrips. The disease cannot be treated; it cannot be cured. The diseased specimen will have to be thrown away. And other indoor plants need to be inspected for the presence of thrips so that they cannot spread the bronzing virus. For processing, you can use Actellik or Aktar.
Non-communicable diseases
The appearance of diseases is promoted by improper care of plants. Non-infectious diseases include smallpox, chlorosis, enation.
Plant pox
When a disease is caused by errors in care, various raised spots appear on the leaves. They can be yellow or yellowish-green in color. Such deformity of leaf plates can occur when the air humidity does not match the temperature.
On a note! We must not forget about timely feeding of anthuriums. After all, healthy specimens are less susceptible to diseases.
Chlorosis
The disease occurs as a result of a deficiency of two important elements– iron and magnesium. Their deficiency manifests itself in yellowing of the foliage or the appearance of yellow stains on the leaf blades.
Enatsii
The disease can be recognized by its ugly leaves. The first sign is that the foliage began to grow unevenly, the plates themselves become convex and humpbacked. Incorrect temperature contributes to the appearance of enation. The room may be too stuffy, too cold, dry or humid. Getting rid of the problem will help by establishing proper care for the plant and following agrotechnical growing practices.
- thrips;
- spider mite;
- scale insect.
Aphids are a malicious pest; it is advisable to fight them before the insects multiply. When a plant is massively infested with aphids, it becomes increasingly difficult to cure the flower. Can be used for fighting chemicals or apply mechanical method control: hang sticky tapes to catch flies near the plant itself.
The flower is suffering from a thrips invasion. To understand that this particular pest has infested the plant, you need to carefully examine the underside of the leaves. Black dots indicate its presence. The insect is active in spring and summer.
Not only adult thrips are dangerous, but also their larvae. Feeding on the sap of the plant, they gradually lead to its death. Thrips can be controlled using pesticides. It is better to buy in specialized stores, paying attention to the expiration date of the drug.
Insects appear on plants that are not properly cared for. To minimize errors, you need to carefully monitor the anthurium, water it on time, feed it and, of course, provide the plant with an influx of fresh air, carrying out daily ventilation of the room.
If an anthurium is damaged by a scale insect, you need to prepare for the fact that the fight against it will be lengthy. And it depends only on the persistence of the owner whether the result will be positive or negative. At the early stage of pest appearance, it is unlikely that you will be able to see them with the naked eye. The bugs have a strong shell, so when processing chemicals the result is not always good.
Before spraying the plant with insecticides, you need to soap the sponge with laundry soap and wipe the plant itself, leaving the soap foam on the flower for half an hour. Then you need to wash the flower in the shower, let it dry and only then carry out the treatment.
You need to spray the plant 3 times with an interval of 7 days. If this condition is not met, scale insects will appear again, since some of the adult individuals are in the soil.
Attention! When treating anthurium against scale insects, you need to spill the soil with a weak solution of the prepared preparation, or even better, replace the old soil with new one.
Spider mites are no less dangerous pests. Thanks to its vital activity, the leaves of the plant begin to turn yellow, gradually curl and fall off. You can tell that there is a spider mite infestation by looking at the thin web that will be located on the back side leaf.
The pest can be controlled with folk remedies. First you need to wash the plant in the shower and free it from cobwebs. Then you need to wipe the surface of the leaves, the pot itself, and the window sill on which the anthurium stood with a sponge and laundry soap.
Basic care mistakes lead to problems with growing anthurium: video
In addition to diseases caused by viruses, as well as infectious and non-infectious diseases, with improper care you can encounter a number of problems that inhibit plant growth and can lead to disease:
- Irregularly shaped spots on the leaves and the presence of black spots. Such symptoms appear when the pet is kept in a cold room. The problem can be solved by moving the pot with the plant to a warmer room. You cannot water anthurium more often than it should. The plant does not like stagnant water.
- The leaf blades turn yellow and dry out at the edges. If you keep anthurium in a brightly lit place, for example, on a southern windowsill, its foliage will certainly get burned. The problem can be solved by moving the plant to a place with diffused lighting.
- Yellowing and wilting of foliage. The plant does not like the air temperature in the room. For normal growth and development, the optimal air temperature is + 22 °C. During winter dormancy, the plant needs to be kept in conditions at a temperature of + 16 °C.
- The tips of the leaves turn black. This a clear sign the fact that the soil contains quite a lot of nutrients, especially calcium. To solve the problem, you need to transplant the flower into new nutritious soil.
- Why doesn't anthurium bloom? It is possible that the plant is growing in a dimly lit place and is planted in a pot that is too spacious. The lack of flowering is also affected by low humidity.
- Why does the foliage curl into a tube? The problem may be that the lighting is too bright. In order for the leaves to return to their original position, you will need to remove the flower away from direct sunlight.
- The foliage turns black. Perhaps the reason lies in watering the plant too hard, chlorinated or cold water. After watering, it is important to ensure that the pot stands in a dry tray. If the plant does not drink all the water, it must be drained from the pan, otherwise the root system may rot. In order to soften the water, you need to add a pinch of citric acid or a drop of lemon juice. It is advisable to water with settled water heated to room temperature. When watering, you must follow Golden Rule- everything is good in moderation.
