The main diseases and pests of anthurium


Anthurium, a plant with a large, elastic leaf plate and any violation of the conditions of detention, will immediately affect its appearance. With gross disregard for the rules of care, diseases and pests attack the flower. They mainly affect young, not matured plants. Many diseases are difficult to treat and the plant dies.

Consider the most common disease, anthurium

It is considered not parasitic, that is, not an infectious disease. The exact reason for its occurrence has not yet been determined, but it is assumed that the plant becomes ill due to sudden changes in humidity and temperature. The leaf plate of the diseased plant is deformed, rounded. On it appear growths. Anthurium begins to grow unevenly.

The treatment does not require isolation of the plant. It is enough to treat the plant with the preparations “Antitlin”, “Fitoverm”, “Detsis”

Stem rot

Not a parasitic disease, but fungal. The cause is the high humidity of the soil and air in the room where the plant is contained. Recognized, by dark, water spots. The spores of the fungus, at the initial stage of their development are white, and then acquire a black color. The disease first appears on the shoots, and then goes to the trunk and can lead to the death of the plant.

When the first signs of the disease appear, the flower must immediately be isolated from other plants, sent to quarantine. Cut off the diseased leaves and process the plant with fungicides: “Rovral”, “Saprolo” or “Fitosparin - M”, “Alirin - B” bioproducts. You can also treat the plant with copper sulphate. Under the film, which it forms spores of the fungus, do not survive. If after treatment the disease does not recede, the plant should be disposed of, in order to avoid infecting other plants.

A contagious, fungal disease caused by spores of the fungus Puccinia anthirrhini Diet Et Holw. Causes of the disease is considered to be high humidity and low temperature in the room. In conjunction with high soil moisture get this result. Spots with spores appear on the stem and leaf plate, rusty yellow. Sheet dries and falls. Without treatment, the plant dies.

Affected leaves are cut off, and the remaining ones are rubbed with Bordeaux mixture. You can also wipe the leaves with furgicides: "Rovral", "Saprolo". It is forbidden to spray the plant, as this can infect healthy sheets.

Anthracosis or powdery mildew

A viral disease that is caused by the mushroom Solletorichum. The cause of the disease is increased humidity of air and soil. At first the leaf is affected, brown spots appear on it, with black dots in the center - these are fungal spores. At high humidity spores germinate well and fly away. The leaf becomes colorless, shrinks and falls off. From the leaf plate disease can go to the root of the plant. Distributors of the disease are pests, thrips.
There is downy mildew, which is caused by the fungus Peronospora anthirrhini. The spores of the fungus are gray. In the affected plant, the leaf plate is covered with chlorotic spots, the leaf becomes small. Such a plant grows crowded.

During treatment, watering should be reduced, fungicidal preparations “Saprolo”, “Rovral” should be used. Sprinkle the plant with blue vitriol.

A terrible disease caused by spores of the fungus Septoria. High temperature and high humidity provoke the development of the disease. A leaf plate of the plant is affected. Brown or red spots appear on it, with a yellow rim. Under the magnifying glass or magnifying glass you can see the black dots - this is a controversy. Under their influence, the leaf dries, and the spores of the fungus move to other, healthy sheets and infect them.

Starting treatment, the affected plant is sent to quarantine, in order to avoid infecting other plants. Then they start treating the leaves with copper-containing preparations, as well as with the preparations "Fitosparin", "Arilin". If a week, the treatment does not bring a positive result, the plant should be disposed of.

Fusarium wilt

Severe, fungal disease caused by Fusarium spores. The reasons for the appearance of the fungus are a combination of abundant watering and moist air, as well as a long stay of the plant in a moist environment. The first sign to which attention should be paid is the unnatural curvature of the peduncle, in consequence of the deformation and curvature in one direction. Dark spots appear on the leaf plate - dead tissue, with a light fungal patina. Leaf fades and falls. Without proper treatment, the disease affects the stem. In the zone of the root collar, a white - pink bloom forms, the spores of the fungus spread in irrigation water, the root system is affected, the plant dies.

When starting treatment, the first thing that is required is the complete isolation of the plant. Then you should treat the soil in which the plant is located, the drug "Glyocladin". It is better to transplant the plant into a new soil, removing the old soil from the roots. When using an old pot, it should either be ignited or boiled over. Cut off the damaged leaves and process "Fundazole." To get rid of anthurium from this disease is difficult, so start treatment as soon as possible.

Gray mold

Basically this disease affects young, not grown up plants. The reasons are in violation of the rules for care, namely abundant watering and poor drainage. As well as a long stay in a poorly ventilated room and not timely removal of dry sheets and parts of the plant. The defeat starts from the trunk and reaches the shoots, and only after that goes to the leaf. Manifested in the appearance of gray bloom. The disease spreads very quickly and in a short time, it can hit the whole bush.

Treatment should begin immediately.
The affected leaves can no longer be saved, so they need to be removed. The plant is isolated and subjected to treatment with fungicides "Fitosparin-m", "Rovral".

Black mushrooms

Infectious, fungal disease. Due to the lack of nutrients and is associated with the appearance of pests - thrips and aphids. Fungi live on thrips and aphids sugar secretions. Infected leaf acquires a yellowish-white color. Also prone to disease stem and young shoots. The plant does not multiply.

Before starting treatment, the plant should be isolated. The affected leaves can no longer be restored, therefore, it is better to cut them off. At the initial stage of the disease, the plant can be treated with potassium soap. A good effect is given by the use of the drugs "Fitoverm", "Intavir", "Lightning".

This disease is not contagious. It is associated with improper care, high humidity, low temperature and late feeding. Damage to the root system is also possible. As a result, the sheet plate is deformed, bulges of rounded shape appear on it, with green-yellow growths.

The treatment is to reduce watering and move the anthurium pot to a warmer place. Avoid direct sunlight. Insulation is required.

Root rot

Infectious disease caused by soil fungi. Causes of occurrence, abundant watering, because of which the increased soil moisture, poor drainage and low acidity of the soil. Also, the reason may be contaminated soil. The sheet plate becomes pale green or matte. Over time, it turns yellow, fades and dies. The disease affects the root system. The roots of the plant turn black, become soft. The root shell is behind the middle. From the side it looks unsightly, frayed. There is a process of decay.

Serious disease, difficult to treat. The plant is transplanted into a new pot with coarse grain primer. Pre-well shaking off the old soil from the roots.

Before planting for a short time, soak the roots of the plant in "Fitosparine" or "Alirine." And after transplantation, pour anthurium under the root of the same drugs. Old, contaminated land is best disposed of.

Leaf diseases: description and reasons, photo

Anthurium diseases can be not only fungal. There are also viral diseases, infectious and non-infectious. Flower treatment for diseases is impossible alone with folk remedies. It is necessary to apply more fungicides. Such drugs as Fitosporin-M, Fundazol have recommended themselves well.

Before processing the pot with a flower is placed in a large plastic bag. After spraying, the bag is tied and the plant is left in such a mini-greenhouse for 15 minutes. When time passes, remove the anthurium from the bag, let it dry and return to its original place.

After the first main treatment, 7 days should pass, then the treatment should be repeated. Be sure to third spraying, which is held a week after the second treatment.

Infectious diseases

Among the diseases spread by infection can be distinguished septoria, fusarium wilt. If it is too late to identify the disease, it will be practically impossible to cure it.

The presence of the disease is indicated by brown spots on the leaves of plants. Usually they have an irregular shape, with brown or yellow girdles around the edges. If you look at the spots through a magnifying glass, you can see small black dots in the middle - sporangia.

How to treat anthurium leaves for septoria?

With a strong defeat, septoriozm will have to cut off all the foliage and burn. In the room should reduce the humidity. It is recommended to exclude such a procedure for the care of a plant as spraying the foliage.

The flower needs additional fertilizing with complex fertilizers for flowering plants. After inspecting for pests, anthurium should be treated with copper-containing drugs or sprayed with Fitosporin-M.

Mealy dew

It would seem that the plant likes everything, it is fragrant and pleases the eye, and suddenly a strange fall of leaves begins. What is the reason, Why did the plant start to turn yellow and dry leaves? On the defeat of powdery mildew indicates white bloom, which spreads throughout the green mass of the plant. Good result gives treatment with Topaz.

Bronze virus

An unpleasant disease that manifests by discoloration of the foliage of plants. With the armed eye on the surface of the sheet you can notice pronounced wrinkles, small through points.

The virus is spread by insects, for example, thrips. It is impossible to treat the disease, it is not treatable. Sick instance will have to throw away. And other indoor plants need to inspect for the presence of thrips, so that they could not spread the virus of bronze. Actellic or Aktar can be used for processing.

Plant pox

In case of a disease caused by care errors, various bulging spots appear on the leaves. They can be colored yellow or yellowish green. Such ugliness of leaf plates can occur when the air humidity does not match temperature.

The disease results from the deficiency of two important elements - iron and magnesium. Their lack is manifested in the yellowing of the foliage or in the appearance of yellow streaks on the leaf plates.

The disease can be identified by ugly leaves. The first sign - the foliage began to grow unevenly, the plates themselves become convex and hunchbacked. The appearance of enation contributes to the wrong temperature content. Indoors it can be either too hot, or too cold, or dry, or humid. Getting rid of the problem will help the establishment of proper care for the plant and compliance with the agrotechnical methods of cultivation.

Parasitic diseases: anthurium pests

Parasitic diseases should be attributed to a separate group of diseases. Strangely enough, but even those plants that are properly cared for are affected by these diseases. With the defeat of pests leaves, flowers, root system and green shoots suffer. The main pests of anthurium include:

Aphid is a malicious pest, it is desirable to fight with it until insects have multiplied. When a plant is massively affected by an aphid, it becomes increasingly difficult to cure a flower. To fight you can use chemicals or use a mechanical method of struggle: hang sticky tape for catching flies near the plant itself.

The flower suffers from the invasion of thrips. To understand that it was this pest that started up on the plant, you need to carefully inspect the underside of the leaves. His presence is indicated by black dots. The insect is active in spring and summer.

Not only adult trips are dangerous, but also their larvae. Feeding on the sap of the plant, they gradually lead to its death. To deal with thrips, you can use pesticides. It is better to buy in specialized stores, paying attention to the shelf life of the drug.

Insects appear on the plants, for which the wrong care. To minimize errors, it is necessary to carefully observe the anthurium, water it in time, feed it and, if necessary, provide the plant with fresh air, carrying out daily ventilation of the room.

If the anthurium is damaged by the shield - you need to prepare for the fact that the fight against it will be long. And only on the perseverance of the owner depends on whether the result is positive or negative. At the early stage of the appearance of pests, it is unlikely that they can be seen with the naked eye. Bugs have a durable shell, so when processed by chemical means is not always a good result.

Before spraying the plant with insecticides, you need to soap the sponge with laundry soap and wipe the plant itself, leaving the foam on the flower for half an hour. Then you need to wash the flower under the shower, let it dry, and only then do the processing.

It is necessary to spray a plant 3 times with an interval of 7 days. If this condition is not met, the scale insects will reappear, as some adults are in the soil.

Spider mite is a no less dangerous pest. Due to its vital activity, the leaves of the plant begin to turn yellow, gradually twisting and falling. Understand that the spider mite was wound up, it is possible by a thin spider web, which will be located on the back of the sheet.

With the pest can handle folk remedies. First you need to wash the plant under the shower, to release from the web. Then you want to wipe the surface of the leaves, the pot itself, and the window sill, on which stood the anthurium, with a sponge with soap.

What does anthurium look like: photo

In the photo in our gallery you can see what this flower looks like. He's very handsome, refers to evergreens. Anthurium comes from the tropics, and its flowers have a special fanciful shape, so it is often called the flamingo flower.

Anthurium is very popular among amateur and professional florists. It itself looks unusual, and it can also be used differently in different flower arrangements and bouquets. If desired, you can find photos of examples of such combinations.

Another feature of the plant is the ability to stand cut in a vase for several weeks in a row.

However, there are a number of anthurium diseases that affect the leaves of the plant. They give the owners a lot of trouble. Most flower growers believe that they are better prevented than cured after the fact.

Causes of yellow leaves

The key to beautiful anthurium bloom is proper care. If you neglect the rules and advice on this matter, the leaves of the plant will turn yellow. This is very bad, since such a phenomenon is not characteristic of anthurium.

Leaves turn yellow for such reasons as:

  • problems with care,
  • chlorosis,
  • sunburn
  • flower freezing
  • other diseases.

If you notice that the leaves of anthurium began to turn yellow, then pay attention to how you water it, perhaps there is not enough wateror it is too hard. It may also be a lack of fertilizer or lack of sunlight. As a treatment, you just need to revise the irrigation schedule and rearrange the pot.

Yellowing and treatment of diseases

If the leaves of anthurium turn yellow due to the disease, then you need to identify it and begin the required treatment. So, if we are talking about chlorosis, then you need to spray the plant with iron chelate or algae extract. With this disease, the normal color of the vein is preserved, and the leaf turns yellow. Also Anthurium will need more light.

Also leaves may turn yellow due to sunburn. That is why you can not overdo it in terms of the sun. A characteristic symptom is yellow or brown spots on the leaves, then they themselves begin to curl and eventually dry. The best treatment in this case would be a permutation of a flower for some time in a darkened place.

You can not put anthurium in the draft and use for watering very cold water. In this case, it can freeze, which is why small white spots will appear on the leaves. In such cases, they must be transferred to warmer places.

Помимо этого, желтые листья могут сигнализировать о наличии грибков. О них мы поговорим чуть позже.

Почему листья антуриума чернеют?

Листья антуриума могут менять цвет вследствие неправильного ухода. Пятна коричневого оттенка may appear due to abundant watering. It is better to know the measure in this matter, otherwise the plant will die.

Black and sluggish leaves - a sign of improper transplant plants. It is best to use a substrate for bromeliads or orchids, which will allow the flower to grow fully. It includes soils such as:

It also contains a mixture based on sand.

In addition to unsuitable soil, the cause of leaf darkening during transplantation is root system damage, the risk to damage it always exists, so carefully read in advance how to do it.

Sometimes diseases of the root system and anthurium flowers occur due to strong temperature extremes. Brown heel and holes along the edges lead to the death of the plant, and there will simply be no time to heal. Therefore, it is better to properly care for this to prevent.

What are the most affected anthurium leaves?

Various diseases can concern both room samples, and garden. If they are improperly cared for or planted incorrectly, their leaves may be affected by fungi and parasites. This is especially true for transplantation, here the risk is especially great.

Immediately remove the diseased plant from healthy, in order to avoid infection, it is necessary in the presence of such symptoms:

  • specific spots,
  • raid on the leaves,
  • dryness both on the leaves and on the trunks.

Treatment in this case should be started immediately. using special meansto save the flower.

The most common fungal diseases of anthurium are:

  • black fungi,
  • gray mold,
  • soil mushrooms,
  • rust,
  • powdery mildew and rot.

Yellowing of Anthurium foliage depends on many factors. For example:

  • excessive soil moisture,
  • cramped pot
  • nutritional deficiencies
  • lack of optimal lighting
  • cold air,
  • the presence of drafts,
  • poor soil.

To understand the reason for the yellowing of the foliage, it will be necessary to analyze the growing conditions and identify misses to correct the situation for the better.

Preventive measures

Proper care of green pets allows you to avoid a lot of problems. Timely and rational watering, sufficient fertilization, optimal lighting and air temperature will allow the flower to feel good and delight the owner with its beautiful flowering.

Unlike fungal diseases, which often appear with improper care, parasitic diseases damage even well-kept plants. To avoid many problems, you need to carefully monitor the anthurium and inspect the leaves for the presence of pests.

For preventive purposes, it is recommended to arrange the shower plant from time to time, to wash it with a solution of laundry soap. And if the pests were still noticed, it is necessary to immediately begin to combat them.


Houseplant anthurium disease which can be caused by various infections, with proper care, it is possible to reduce the risk of developing various diseases. Compliance with agricultural practices allows you to have in the house a beautiful and healthy plant, which pleases with its long flowering.

Non-infectious diseases of anthurium, methods of their elimination

Non-communicable diseases of anthurium - The most common problem, often arising in the process of growing not only anthurium, but also other household plants. As a rule, they are associated with violations of the rules of content or their drastic change.

Watering frequency and water hardness, land quality, soil feeding, light, fresh air and much more - all this together determines the rate of anthurium growth and flowering, which is why you should be very scrupulous, and in case of problems and diseases, pay attention to change of conditions.

Anthurium does not bloom

In matters of non-communicable plant diseases, anthurium differs little from other flowers. This allows not only to easily determine the cause of the problem, but also ways to solve it. As with any other flower, anthurium diseases sometimes affect its flowering, simply stopping it.

This can be caused by the infectious component, but, as a rule, the reason lies in violation of the rules of the content. So, Anthurium at home should be kept at a temperature of at least 18 ° C, in the absence of drafts, and also hidden from direct sunlight.

Solving problems with absent flowering is quite simple: you just need to create "greenhouse" conditions of maintenance and feed the root system with mineral fertilizers.

Why anthurium dries out

As in the case of the first problem of the disease state of anthurium, in most cases the plant dries up due to non-compliance with the conditions of detention. Anthurium leaves dry up primarily due to insufficient watering and low room temperature..

In such a situation, it is extremely important to quickly change the conditions of detention in the direction of improvement and it is desirable to feed the plant with mineral fertilizers.

In the case of correct and timely action, problems like “leaves dry at the anthurium” are usually solved, but options are possible when the cause is infectious septoriosis and anthracnose, the methods of which are not non-infectious and will be described below.

Yellowing of the leaves (chlorosis)

Answering the question why anthurium is sick, it is absolutely possible to say that the main problem is growing conditions and improper care. Chlorosisthat causes stains on the leaves of anthurium, is a consequence of the violation of the microelement composition in the feed water, soil and fertilizer.

Moreover, the essence of the problem can be hidden in one of the factors, and in all at the same time, so you need to eliminate them all without exception. Among the causes and factors can be noted:

  • inconsistency of the soil and the absence of a drainage system, which prevents the free access of oxygen and water,
  • overestimate of chlorine in water
  • Excessive natural lighting
  • the presence of drafts,
  • excessive watering or watering is not enough warm water
  • Anthurium infectious diseases.

From this it follows that anthurium languishes due to the banal problems inherent in other home plants. Treatment - the creation of proper conditions for the maintenance of anthurium, the provision of irrigation with settled water, as well as regular feeding with mineral fertilizers.

Leaf spotting (burns)

Violation of care for anthurium at home in some cases contributes to the appearance of some spotting on the leaves, that is, burns. Brown spots on anthurium leaves can be caused by the following factors:

  • excessive moisture content and lack of proper drainage,
  • landing in poor quality soil, with the absence or low content of minerals,
  • improper watering
  • hypothermia

Vegetable Enaciamanifested by the fact that anthurium wasting away, its leaves acquire an ugly form and are often ugly with growths. The nature of this non-infectious disease is not fully understood, however, exactly the problems of this kind arise after an abrupt change in the temperature regimes of the content. Enacii can be cured solely by the creation of favorable conditions, proper care and regular fertilizer of the flower.

Smallpox - non-parasitic disease peculiar to plants that have undergone a sharp deterioration in conditions of maintenance and care. It is manifested by the appearance of growths and bulges on the sheets. To get rid of smallpox is quite simple - you need to move the pot with a flower in a warm place, protected from drafts and direct sunlight.

Anthurium infectious diseases, their treatment

Infectious diseases of anthurium in the home are quite common, which is caused by many factors, including the tropical origin of this plant, its preferences for conditions of detention and the requirements for care.

A variety of infectious diseases affects, but do not be afraid and give up, because almost every one of them can easily be won on your own at home. The main thing is to understand why the leaves turn black, the flowers fall, spots and other problems appear in Anthurium.

Septoria and anthracnosis

Anthurium septoria, as well as anthracnose - fungal infectious diseases, manifested in the form of spots of red and brown. With these diseases, the tips of the leaves often turn black.

The treatment of anthracnose anthurium is similar to the measures prescribed for the treatment of septoriosis - immediate treatment with mineral chemicals, removal of infected areas, thorough washing of the flower.

In the absence of an effective result during the week, the flower must be destroyed, and the pot must be treated with chemical compositions and high temperature.

Gray rot

Infectious disease of this type begins its spread with a lesion of the stem and shoots of the flower, gradually spreading to the leaves. In a short time plots gray rot plants die off,therefore, the treatment of plant sulfur rot must begin immediately.

As a rule, experts recommend resorting to the use of chemical compounds, completely abandoning the popular methods, referring to their low efficiency in this matter. The affected leaves are removed, after which the flower is treated with medicine.

There should be at least three cycles of such processing. If there is no proper result, the plant should be destroyed and the pot should be disinfected.


Redhead - One of the most simple and visible pests. From the very first days of its settlement on the plant, the surface of the leaves is covered with white bloom, which makes it possible to detect the worm.

Along with other pests, it feeds on the sap and surface layer of the plant, which undoubtedly ruins anthurium. Fortunately, a powdery mealybug can be tackled by simply treating it with a soap or alcohol solution and then rinsing it with warm filtered water.

To fix the effect, such treatment should be repeated at least twice, with a weekly interval.
