Frequent diseases of anthurium. Why do brown spots appear on the leaves of anthurium Anthurium flower how to cure rusty leaves

Many flower growers consider anthurium a capricious plant, for its successful growth and development, as well as for lush flowering, you will have to create a piece of the South American tropics in your apartment. If the conditions of detention are not observed, the anthurium can get sick or be attacked by pests.

Optimal conditions for growing anthurium

What conditions are used to anthurium in nature, and what should the grower strive for when growing "male happiness"?

First of all - high humidity, up to 70-80%. It is rather difficult to provide it in an apartment, especially in winter with central heating: either by regular spraying 2-3 times a day, or by placing a flower pot on a wide pallet with wet expanded clay, which does not always look aesthetically pleasing. In addition, when spraying from a spray bottle, white spots may remain on the bracts, so the flowers should be covered from water drops, which is also very inconvenient. A little financially expensive, but much more effective - to put a humidifier nearby. But even in this case, once a week, wipe the leaves from accumulated dust with a damp sponge.

It is impossible to increase the humidity of the air by excessive watering of the anthurium.

The next step to a healthy anthurium is a constant temperature that does not fall below 18 degrees in summer and 16 degrees in winter. It is optimal from May to September to keep anthurium at a temperature of 25–28 degrees. Drafts and even warm breezes are absolutely contraindicated. The roots of the plant can rot, and the leaves and flowers can freeze.

Spraying the plant in winter and opening the window for ventilation is almost a 100% way to kill anthurium.

Bright light and day length is very necessary for laying flower buds and powerful further flowering. But at the same time, the plant should not be placed under direct Sun rays, because in tropical forests it is covered from the sun by the leaves of trees.

Place the anthurium in a well-lit place without direct sunlight, and in winter, do additional lighting 4-5 hours a day.

The last condition is watering and soil. Anthurium loves loose moist soils, this epiphytic plant, almost like an orchid, can grow on tree branches, and in order not to be mistaken, choose soil mixtures specially selected for anthurium.

It should be watered with soft settled water as the soil dries out, but if you maintain high humidity, then watering will have to be done infrequently.

The best water for irrigation and spraying is rainwater or melted water.

If the conditions of detention are violated, pests may appear on the anthurium or the flower may get sick.

Diagnosis of diseases of "male happiness"

All the problems of growing anthurium can be divided into leaf diseases, peduncles diseases, root diseases, the general unsatisfactory condition of anthurium, which are caused by the presence of pests, infectious diseases or simply care errors.

To correctly diagnose and start timely treatment is difficult task for the grower, since the symptoms of various diseases are often similar to the consequences of improper care.

It is important to know that the anthurium kept in a dry room most often suffers from spider mites, the leaves lose their elasticity due to lack of moisture, turn yellow and curl, but these plants are very rarely affected by fungal and bacterial diseases.

In humid conditions without ventilation, plants are more likely to suffer from soil overflow, and as a result, they suffer from infectious diseases.

Having assessed the condition of your premises and the care provided, you can more or less accurately decide how to help the anthurium.

Table - diagnosis of plant diseases and pests

Causes	Symptoms
Dry room air	dry and yellow leaves around the edges leaves curl and turn black the plant becomes lethargic, the leaves lose elasticity drying of unopened buds, aggravated by rare watering
Bright light or direct sunlight	leaves are twisted into a tube, deformed the leaf plate is covered with whitish spots, dries
lack of light	leaf yellowing stretching of petioles lack of flowering
Watering with hard water, excess calcium	blackened leaf tips
Watering cold water	leaves dry, forming round holes root rot
Waterlogging of the soil, overflow	yellowing and drying of leaves the appearance of black dots on the leaf plates root death from rot pimples on leaves, peduncles "weeping" leaves the whole flower withers
nutritional deficiency	leaves fade, shrink new flowers bloom anthurium stops blooming
excess nutrition	brown and yellow spots on the leaves without signs of drying out
Watering with chlorinated water	white patches on leaves
Anthurium hypothermia	quickly browned and drooping leaves
natural causes	greening of fading bedspreads young red leaves red veins on leaves thickening of stems with age gradual death of the lower leaves overgrowth with brown scales - the remains of old leaves
Wrong care	ears disappear (flowering stops) plant growth stops no new leaves appear new leaves grow slowly anthurium falls apart (due to water entering the growing point)
Anthracnose and Septoria	Round or oval red-brown, yellow spots from 1.5 to 13 millimeters, often seen inside black dot(disputes). The stain spreads over the sheet and forms holes. Without treatment, the plant dies.
Fusarium wilt	Massive, rapid withering of the leaves and unnatural bending of peduncles and petioles, dark vessels are visible on the cut of the leaves, the roots rot.
The leaves lose their luster, brighten, then turn black. On examination, the roots are rotten and frayed, the root shell is separated from the core.
The leaves curl, turn yellow, shrink, a white coating appears on the underside of the leaf.
Rust	Red- brown spots from the bottom of the leaf and at the same time light spots at the top, the death of the affected leaves.
The leaves curl, turn yellow, covered with a sticky coating. Small green sucking insects are visible inside the leaf and on young shoots.
thrips	Affected leaves have an uneven yellow-green color, inner part The leaf is covered with black insect excrement. The leaves dry up and fall off.
Whitish or golden tubercles on the leaves.
spider mite	The leaf is covered with yellow dots, curls, dries out. With fine spraying, a web with insects is visible.
Mealybug	The affected parts of the plant are as if powdered with flour

Infectious diseases of anthurium in the photo

Anthracnose manifests itself yellow spots with a black dot in the middle Septoria affects the leaves of the plant and can lead to the death of the anthurium. Root rot can often be found in purchased specimens with constant overflow. This is what powdery mildew looks like on Kalanchoe. Anthurium is rarely affected by this disease Fusarium affects both leaves and roots of the plant Anthracnose on a rose: characteristic spots with a brown edging Anthracnose on an anthurium - brown spots with a black accumulation of fungal spores in the center Root rot can kill all the roots of an anthurium Anthurium leaf affected by a fungal disease Fungal disease of the upper leaf moved to the leaf under it. Black roots affected by root rot. There are white healthy roots, therefore, there is a chance to save the plant Anthurium leaf covered with rust Anthurium leaf affected by septoria Septoria is very similar to anthracnose, it is difficult to determine without laboratory analysis Fusarium in asters killed the plant in full bloom Fusarium wilt of violet

Flower diseases, treatment and prevention

Most often, anthurium diseases appear due to improper care, among which the greatest place is occupied by overflow and hypothermia, and as a result of this, rotting of the root system.

Infectious diseases pose a great danger to the plant: anthracnose, fusarium, septoria, as a result of which the plant often dies even after treatment.

It is easier to deal with rust on leaves and various root rots. And almost all plants recover and improve appearance if the cause of the disease was improper care.

Treatment of infectious diseases

Many infectious diseases lead to the death of the plant, but you still need to try to save the plant.

First of all, we isolate the damaged plant from the rest, examine it and make a preliminary diagnosis.

When working with fungicides, be sure to use personal protective equipment, do not eat or drink.

Fusarium wilt is an infectious disease in which the mycelium of the fungus penetrates the living tissue of the plant and clogs vital vessels. Root rot appears, passing into the trunk. Unnourished leaves quickly wither and the plant dies. The best remedy struggle - prevention. When planting, several grains of Trichodermin are added to the soil mixture, maintaining a high vitality of the plant. You can try to save a diseased anthurium by cutting off the living upper part and rooting it, after soaking it in a solution of Fundazol for about 30 minutes.

Root rot most often occurs when the plant is constantly overflowing. Treatment - pruning of rotten parts of the roots and treatment with Fitosporin-M or Maxim, transplanting into a new substrate and preferably a new pot.

Rust is a fungal disease that appears on all parts of the anthurium, but most often on the leaves. For the purpose of prophylaxis at low temperatures and high air humidity, it is possible to carry out treatment with Fitosporin, and with an already appeared disease - with Topaz, Ordan.

Powdery mildew appears with a sharp drop in temperature at high humidity. Preventive measures - do not spray anthurium in cool weather (winter content). Powdery mildew treatment - put the pot in a warm, dry place, spray with Topaz or Acrobat preparations.

Anthracnose appears due to high humidity, which is exactly what anthurium loves. The causative agents of the disease - fungi of the genus Colletotrichum and Kabatiella - may not manifest themselves for a long time, and when favorable conditions occur for them, they begin to infect the plant. Usually the first symptoms appear on the leaves in the form of spots, which are becoming more and more. The affected leaf shrinks, becomes thinner and becomes like tissue paper. Further, anthracnose infects the stems and almost the entire plant dries up on the vine. Anthracnose treatment should be started as early as possible. The first step is to remove all damaged leaves and destroy them. The soil is changed to a new one, and the roots of the anthurium are disinfected. The plant is quarantined with a decrease in air humidity and a reduction in watering. It is absolutely impossible to spray, as the spores of the fungus are carried by droplets of water. If the plant is very sick, then fungicides are used: Baktofit, Fitosporin, Fundazol, Ridamin Gold, Silk. Spray the plant 2-3 times in 10-14 days.

Anthurium pests

Often, small midges (wine gnats) become uninvited guests of indoor flowers, although they are unpleasant, they are practically harmless, the appearance of the following insects sucking juice from anthurium is much worse.

It is usually introduced "from the outside" with other plants and spreads very quickly through indoor flowers. For treatment, wash the affected areas with soap and water, after covering the soil with a bag, treat with infusion onion(15 grams of finely chopped onions or 6 grams of dry scales are infused in 1 liter of water for 5–7 hours), Fitoverm, and in advanced cases - Actellik, Karbofos, Fitoverm, Iskra, Biotlin.

thrips. Thin midges up to 2 mm long. They suck the juices from the leaf. Occurs in damp environments high temperature. Treat with Fitoverm, diluting according to the instructions on the package. Processing is carried out several times every 5-7 days.

Shchitovki. They cover not only the leaves, but also the stems of the plant, suck out the juices, and are easily removed with a needle. Since the insects are covered with thick scales, it is necessary to manually collect the scale insects, and then treat the anthurium with a solution of crushed garlic (mix 1 part of garlic with 1 part of soap and 3 parts of water, insist for a day), if it does not help, wipe the stems with a cotton pad soaked in kerosene.

spider mite. Appears in a dry and hot place. It entangles young shoots with cobwebs, sucks the juices from the leaves, and leads to the death of most of the leaves. It is better to immediately apply Fitoverm, and not only on the affected plant, but also treat neighboring plants for prevention.

Mealybug. White fluffy insect 4–5 mm long. With mass reproduction leads to the death of the plant. Small colonies of the pest are removed by wiping the affected parts of the plant with soapy water and then every 7–10 days with repeated procedures, as well as spraying with garlic infusion. Heavily damaged plants are sprayed with Fitoverm.

Scale insects suck juices from leaves and stems Aphids can cause great damage to young leaves of anthurium Spider mites drink juices from leaves, drying them up mealybug colonies on the anthurium stem can destroy the plant Thrips appear in a humid room and at high temperatures The scale on anthurium looks like brown tubercles, easily removed with a needle Spider mite leaves such traces on anthurium leaves It is difficult to notice thrips, but the affected areas and excrement are very clearly visible

Prevention of the appearance of any insects is regular care of the plants, wiping the leaves from dust, quarantine for new plants for two weeks.

We reanimate the anthurium after care errors

Many flower growers misunderstand the advice of maintaining high humidity for anthurium and begin to flood the plant. As a result of such care - rotting of the roots, which is manifested by various spots on the leaves.

Too caring owner poured the anthurium and got such spots Bubbles on the leaves and peduncles - a sign of frequent overflow of the anthurium Spots on the anthurium can appear for several days, even after transplanting into dry soil The appearance of various brown dry spots on the anthurium is a sign of overflow, cold content and damage to the roots side of the frozen leaf With poor packaging in stores, flowers often freeze slightly

Revival of a plant affected by rot

In cold and wet ground, the roots of anthurium often rot, the leaves begin to wither, dry out, and fall. If the plant is neglected to such an extent that there is not a single living leaf left, then there is very little chance of resuscitation.

We save the anthurium that has lost its roots

Various rots and infections often begin with root rot. And sometimes there is nothing to save there, but if the leaves and trunk of the plant are alive and without signs of a mass disease, then you can try to root the upper part of the anthurium with aerial roots.

Saving a frozen flower

If the leaves of the anthurium are slightly frozen, then a healthy plant will be able to recover. It is much worse if, shortly before this, the anthurium was watered and the roots were subjected to hypothermia. All damaged leaves should be cut off, the plant should be transferred to a warm room and sprayed with a solution of the HB-101 vitalizer. If in the following days the plant becomes worse, then the roots are damaged, and the plant should be immediately transplanted, cutting off all rotten areas, and treat the cuts with cinnamon. The HB-101 stimulator can be sprayed and watered with a plant to strengthen immunity.

Video - disease prevention

An important prevention of anthurium diseases are regular inspections of the plant, which are carried out when rubbing the leaves. Then you definitely will not miss the alarming signs of the onset of the disease and will be able to treat the plant in time. And in order for it not to hurt, follow the conditions of detention.

Anthurium is a perennial houseplant that looks attractive regardless of the time of year. The flower is especially beautiful during flowering, when bedspreads of pink, white, purple and red colors appear on the plant. This is not to say that the plant is capricious, but with improper care it can get sick. In this article, consider the question: Anthurium disease, caused by viruses, infectious and non-infectious way. We will try to deal with the causes of yellowing of foliage and consider the question of how to avoid mistakes when growing anthurium at home.

Anthurium is an evergreen plant. Tropics are considered the birthplace of the flower. Especially beautiful during flowering. It is for the bizarre shape of the flowers that anthurium is called flamingo flowers.

The flower, the photo of which can be seen in our gallery, is a success both among simple amateur flower growers and among professional collectors. Home anthurium can be used for interior decoration, leaves and flowers are used to compose compositions and chic bouquets.

The flower is notable for the fact that it can stand in a vase for a long time in a cut form. However, there are many diseases that this beautiful plant is susceptible to.

Leaf diseases: description and causes, photo

Anthurium diseases can be not only fungal. There are also viral diseases, infectious and non-infectious. Treatment of a flower from diseases is impossible only folk remedies. More fungicides need to be applied. Such drugs as Fitosporin-M, Fundazol have proven themselves well.

Treatment with drugs should be carried out in well-ventilated areas or, in general, take plants outside.

Before processing, the flower pot is placed in a large plastic bag. After spraying, the bag is tied up and the plant is left in such a mini-greenhouse for 15 minutes. When time passes, 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. Mandatory third spraying, which is carried out a week after the second treatment.

Fungal diseases of the flower, causes and treatment of anthurium

Anthurium fungal diseases 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 temperature lead to a disease such as root rot. When the root system is affected, the leaves become much lighter than usual, then turn yellow and wither.

If you take the plant out of the pot and examine its roots, you can see that they have lost turgor, become lethargic and soft. If you take a closer look, then, starting from the middle, the roots begin to delaminate and hang like “rags”.

If the disease is in early stage, it is necessary to stop watering, remove the plant from the ground, let the earthy coma dry and transplant it into a new nutrient soil. It is important to monitor the humidity in the room.

If, upon inspection of the plant, it is found that the roots are badly damaged, it is necessary to cut off all damaged parts to healthy tissue. The cut points must be sprinkled with crushed coal.

Attention! When planting in new soil, you can not forget about the drainage layer, which will not allow the roots to rot. Expanded clay can be used as drainage.

For watering the plant, it is important to use water with Alirin-B or Fitosporin-M preparations 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 is affected, 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 can occur due to excessive watering and constant maintenance of soil moisture. The decisive factor is also the low temperature in the room.

At the beginning of the disease, vague, black-colored watery spots 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 closer, that is, through a magnifying glass, you can see a huge number of sporangia. First they are whitish, then they turn black.

Patient 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 between sprayings of 1 week.

If the disease is running, it is possible that the plant can no longer be helped. You need to gain strength and throw away the flower. And all the other plants with which the anthurium grew, inspect for the disease.

Infectious diseases

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

Septoria

Brown spots on the leaves of plants indicate the presence of the disease. Usually they have an irregular shape, around the edges they are surrounded by a border of brown or yellow color. If you look at the spots through a magnifying glass, in the middle of them you can see small black dots - sporangia.

How to treat anthurium leaves for septoria?

With a strong defeat, septoria will have to cut off all the foliage and burn it. Reduce the humidity in the room. It is recommended to exclude such a plant care procedure as spraying foliage.

The flower needs to be fed with complex fertilizers for flowering plants. After inspection for pests, the anthurium should be treated with copper-containing preparations or sprayed with Fitosporin-M.

Fusarium wilt

Enough serious illness, in which the foliage wilts en masse. First, it turns yellow, then it dries up and falls off. If you examine the root neck, you can notice a white-pink bloom. An infectious disease spreads during irrigation, when the optimum humidity does not match the temperature.

Attention! So far not found effective way control of Fusarium wilt. You can try to spray the green mass of the plant with fungicides, and shed the soil with pesticides. To save the plant, it is important to try all methods of struggle.

Processing should be carried out three times with an interval of a week. A single treatment never brought a positive result.

Rust

With a disease, spots can be seen on the upper part of the leaf plate. irregular shape, painted in light yellow, and on the underside of the sheet - spots Brown, pustules. With the development of the disease, the spots spread throughout the leaf, the plate withers and dries. Treatment is carried out with the use of fungicides.

powdery mildew

It would seem that the plant likes everything, it is fragrant and pleasing to the eye, and, suddenly, an incomprehensible leaf fall begins. What is the reason , why did the leaves of the plant begin to turn yellow and dry? A plaque testifies to the defeat of powdery mildew white color, which is distributed throughout the green mass of the plant. A good result is obtained by treatment with Topaz.

Viral diseases

Among the viruses that affect anthurium, one can name the bronze virus.

Bronzing virus

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

The virus is spread by insects such as thrips. The disease cannot be cured, it cannot be cured. A diseased copy will have to be thrown away. And others houseplants should be examined for thrips so that they cannot spread the bronze virus. For processing, you can use Actellik or Aktara.

Diseases of a non-infectious nature

The appearance of diseases contributes to improper care of plants. Smallpox, chlorosis, enations are considered non-communicable diseases.

vegetable pox

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

On a note! We must not forget about the timely feeding of anthuriums. After all, healthy specimens are less susceptible to disease.

Chlorosis

The disease occurs as a result of a 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.

Enation

The disease can be recognized by ugly leaves. The first sign is that the foliage began to grow unevenly, the plates themselves become convex and humpbacked. The appearance of enation is facilitated by the wrong temperature of the content. The room can be either too stuffy or too cold, either dry or humid. Establishing proper care for the plant and observing agrotechnical methods of growing will help get rid of the problem.

• thrips;
• spider mite;
• shield.

Aphids are a malicious pest, it is advisable to fight with him until the insects have multiplied. When a plant is massively affected by aphids, it becomes increasingly difficult to cure the flower. To fight, you can use chemicals or apply a mechanical method of struggle: hang sticky tapes for catching flies near the plant itself.

The flower suffers from the invasion of thrips. To understand that it was this pest that wound up on the plant, you need to carefully examine the underside of the leaves. Black dots testify to its presence. The insect is active in spring and summer.

Not only adults of thrips are dangerous, but also their larvae. Feeding on the juice of the plant, they gradually lead to its death. You can fight thrips with 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 in time, feed it and, of course, provide the plant with an influx fresh air, carrying out daily airing of the room.

If the anthurium is damaged by a scab, you need to prepare for the fact that the fight against it will be long. And it depends only on the persistence of the owner whether the result will be positive or negative. At an early stage of the appearance of pests, it is unlikely that they can be seen with the naked eye. The bugs have a strong shell, so when processing chemicals good results are not always obtained.

Before spraying the plant with insecticides, you need to lather the sponge laundry soap and wipe the plant itself, leaving the foam from the soap on the flower for half an hour. Then the flower must be washed in the shower, allowed to dry and only then processed.

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

Attention! When processing anthurium from scale insects, it is necessary to shed the earth with a weak solution of the prepared preparation, and even better, replace the old soil with a new one.

The spider mite is no less dangerous pest. Thanks to its vital activity, the leaves of the plant begin to turn yellow, gradually curl and fall off. You can understand that a spider mite has wound up by a thin cobweb, which will be located on reverse side sheet.

You can deal with the pest with folk remedies. First you need to wash the plant in the shower, free from the 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 with laundry soap.

The main 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:

1. Irregular spots on the leaves and the presence of black dots. Such symptoms appear when keeping a pet in a cold room. The problem can be solved by moving the plant pot to a warmer room. You can not water the anthurium more often than expected. The plant does not like stagnant water.
2. Leaf plates turn yellow, dry out at the edges. If you keep the anthurium in a brightly lit place, for example, on the southern windowsill, its foliage will certainly get burned. You can solve the problem by rearranging the plant in a place with diffused lighting.
3. Yellowing and wilting of foliage. The plant does not like the air temperature in the room. For normal growth and development, the air temperature + 22 ° C is considered optimal. During winter dormancy, the plant needs to be kept at a temperature of + 16 ° C.
4. The tips of the leaves turn black. This is a clear sign that there are quite a lot of nutrients especially calcium. To solve the problem, you need to transplant the flower into a new nutrient soil.
5. Why does anthurium not bloom? It is possible that the plant grows in a dimly lit place, planted too in a spacious pot. The lack of flowering is also affected by low humidity.
6. Why does the leaves roll up into a tube? The problem may be in too bright lighting. In order for the leaves to take their original position, you will need to remove the flower away from the direct rays of the sun.
7. The leaves turn black. Perhaps the reason lies in watering the plant with too hard, chlorinated or cold water. After watering, it is important to ensure that the pot is in a dry pan. If the plant does not drink all the water, it must be drained from the pan, otherwise rotting of the root system can be provoked. In order to soften the water, you need to add a pinch to it. citric acid or a drop of lemon juice. It is desirable to water with settled water heated to room temperature. When watering, you must comply Golden Rule Everything is good in moderation.

Video: the main mistakes in caring for home anthurium.

The yellowing of anthurium foliage depends on many factors. For example:

• excessive soil moisture;
• cramped pot;
• lack of nutrients;
• lack of optimal lighting;
• cold air;
• the presence of drafts;
• poor soil.

To understand what is the reason for the yellowing of the foliage, you will need to analyze the growing conditions and identify misses in order to correct the situation for the better.

Prevention measures

Proper care of green pets can 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.

Conclusion

Houseplant Anthurium whose diseases 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 a beautiful and healthy plant in the house, which pleases with its long flowering.

Anthurium is a beautiful tropical plant that can be a great decoration for any home. For all its external attractiveness, this flower is quite capricious, and a violation of the rules of care can cause yellowing of the leaves or the occurrence of viral and fungal diseases.

In order to prevent the development of anthurium diseases, you need to learn how to correctly identify pathologies and treat them. This article will help you with this: it describes in detail the main diseases of the flower, as well as tips to help cure the plant.

Diseases of the leaves of the Anthurium flower

A healthy anthurium is amazingly beautiful. But under certain conditions, its appearance can change dramatically. A change in the color or structure of the leaves can provoke improper care, exposure to pests or pathogens.

All the reasons that can provoke yellowing, blackening or drying out are usually divided into infectious and non-infectious. The first occurs when the plant is affected by fungi or viruses. The second group of factors is provoked by the owner himself, who could inadvertently violate the rules for caring for a flower.

Since the determination of the method of treatment directly depends on the establishment of the cause of the disease, we will consider each group of factors in more detail.

Noncommunicable diseases

Improper care most often causes leaf diseases in anthurium. Since this flower is found in nature in the tropics, at home it should be provided with conditions similar to the tropical climate.

In addition, in case of violation of agricultural technology, the plant weakens as a whole, and becomes more susceptible to pests and diseases. Therefore, before starting treatment, the culture care schedule should be reviewed. It is possible that it was the non-compliance with the basic recommendations for growing that caused the pathology (Figure 1).

temperature violation

Anthurium is very sensitive to temperature conditions, and if it is not observed, above-ground plants may begin to turn yellow. It is important to remember that in summer time+ 20 + 28 degrees is considered a comfortable temperature for a flower. In winter, this figure is reduced to + 15 + 16.

Figure 1. Yellowing of the leaves in case of violation of the temperature regime, dry air, aging of the culture and improperly selected substrate

Any significant deviation from these indicators can not only provoke yellowing of the leaves, but also cause a lack of flowering. In addition, you should not put the pot with anthurium in a draft, as this culture is very sensitive to cold air currents. Yellowing can also appear in summer if the plant is exposed to direct sunlight for a long time. This process is called leaf burn, and to eliminate it, it is enough to rearrange the flower to another place where the sunlight will be diffused. If this cannot be done, it is enough to lightly shade the plant.

dry air

As mentioned above, under natural conditions, anthurium grows in the tropics, so high humidity is considered habitual for it.

Note: In winter, when the heaters are turned on, the air in the room becomes too dry for the anthurium, and its leaves may begin to turn yellow.

To provide the plant with the required level of humidity, it is necessary not only to develop an optimal irrigation schedule, but also to regularly spray the leaves with settled water at room temperature. In addition, from time to time you need to arrange a plant warm shower, and if the roots of the culture began to protrude above the soil surface, they must be covered with wet sphagnum moss.

plant age

Yellowing of the leaves can also be provoked by an absolutely natural cause - the aging of the plant. In this case, the lower tiers of the leaves of the culture begin to gradually turn yellow and die. This is a completely natural phenomenon of leaf cover renewal, which does not require any treatment.

However, if you notice that not only the lower, but also the upper leaves turn yellow, or uncharacteristic spots and stripes appear on them, you should take action, since such a process is provoked by a fungal or viral disease.

The wrong substrate

Improperly selected soil for growing anthurium can also cause yellowing of the leaves. No matter how strange it may sound, but too fertile soil is not very suitable for anthurium. Quality soil for a flower should be loose and light.

But most often, leaf problems are not caused by the composition of the substrate, but by its density and lack of drainage. In this case, moisture begins to stagnate at the roots. They gradually begin to rot and do not provide the leaves with the necessary amount of nutrients. As a result, they turn yellow, and if measures are not taken in time, the plant may die.

A good substrate for anthurium should consist of hardwood, peat and sand, and a drainage layer must be laid on the bottom of the pot to remove moisture. Without these conditions, every watering will pose a risk to the crop.

Infectious diseases

This group of diseases is provoked by viruses or fungi, but is inextricably linked with the previous paragraphs. The fact is that if the anthurium is not properly cared for and the plant is weakened, it will be more susceptible to the effects of diseases or pests.

Consider the symptoms of the most common infectious diseases of anthurium so that you can independently determine possible problems with a flower.

Septoria

This disease is of fungal origin, and fungal spores spread very quickly in heat and moisture. If it is too hot in the room where the anthurium grows, and the plant itself is watered too intensively, after a while the first signs of fungal pathology may appear on the leaves - brown spots with a specific brown rim (Figure 2).

Figure 2. Signs of septoria

The affected leaf gradually dries up, but the spores of the fungus continue to spread through the air and can infect not only the anthurium itself, but also other plants in the house. To cope with the disease, you need to remove and burn all affected parts of the plant. Next, the aerial parts of the culture are treated with fungicides containing copper. The soil should also be cultivated. For this, the drug Abiga-Peak is used.

Rust

This is one of the most common diseases that occurs not only on indoor flowers, but also on plants that are grown in open ground.

Figure 3. Symptoms of rust on leaves

A characteristic symptom of the disease is a characteristic rusty coating on the lower part of the leaves (Figure 3). The upper part begins to gradually lighten and turn yellow. Over time, the rusty spots completely merge and the leaves dry out. You need to start saving the flower after the first symptoms are detected. In this case, it is necessary to spray the flower with systemic fungicides, after removing the affected parts.

powdery mildew

This disease is also provoked by a fungus and occurs if the room is too hot, and moisture stagnates in a pot with anthurium. It is noteworthy that powdery mildew can spread rapidly, so the fight against it should begin after the first signs are detected.

Distinguishing powdery mildew from other diseases is quite simple: a characteristic powdery coating appears on the leaves. At the same time, the leaf plates themselves begin to deform, decrease in size and gradually dry out.

As with other fungal diseases, powdery mildew should be treated with systemic fungicides. However, it should be borne in mind that this disease develops very quickly, so treatment cannot be postponed.

Virus bronze

Unlike previous diseases, which are most often triggered by improper growing conditions for anthurium, the bronze virus is carried by thrips pests.

This disease also has characteristic symptoms: the leaves begin to gradually discolor, become covered with wrinkles and small holes. You should not wait until the symptoms become more pronounced before starting treatment. Unfortunately, effective methods there is no fight against the bronze virus, so the affected plant must be destroyed along with the soil as soon as possible so that it does not become a source of infection for other crops in the house.

Anthracnose

This disease also applies to fungal infections. It is manifested by the formation of brown spots with black dots on the leaves, which contain spores of the fungus (Figure 4).

Figure 4. Plant damage by anthracnose

It is noteworthy that the fungus develops at high humidity and a temperature of + 23 + 27 degrees, which is comfortable for anthurium. Therefore, when growing such a flower, you need to carefully monitor that moisture does not stagnate in the soil.

To eliminate the disease, it is necessary to carry out a therapeutic treatment with fungicides, strictly observing the dosage indicated in the instructions, and then carry out an extraordinary top dressing with potassium-phosphorus fertilizers.

Fusarium wilt

This disease is accompanied by massive yellowing and wilting of the leaves (Figure 5). Another feature- the formation of a white-pink plaque on the root collar. As with other anthurium diseases, increased temperature and humidity contribute to the spread of pathology.

Figure 5. Signs of Fusarium wilt

To eliminate Fusarium wilt, fungicide treatment should be carried out, and spraying is carried out several times with an interval of two weeks in order to completely destroy the pathogen.

Insect harm

Anthurium can become a victim of pests, and in most cases it is inhabited by insects common to indoor crops. These include thrips, scale insects, aphids and spider mites.

The danger of pests is not only that they feed on the sap of the plant and spoil its appearance, but also that such an effect significantly weakens the culture, making it more susceptible to diseases.

The video discusses the main factors that can cause yellowing of the leaves, as well as the main ways to solve this problem.

-popular exotic flower who came to us from the distant expanses of the tropics of South and Central America.

Due to the incredible color, anthurium is increasingly grown at home, but due to various features This plant is highly susceptible to various diseases.

In order to understand how to save anthurium in case of illness, you need to know what they are.

Non-infectious diseases of anthurium, methods for their elimination

Non-infectious diseases of anthurium- the most common problem that often occurs in the process of growing not only anthurium, but also other domestic plants. As a rule, they are associated with violations of the content rules or their abrupt change.

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

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

Important! In a pot with anthurium, there must be a drainage layer, which will ensure the supply of oxygen to the root system and the removal of excess water. Stagnant water is one of the main enemies of anthurium, so there must be holes in the pot.

Problems with missing flowering are solved quite simply: you just need to create "greenhouse" conditions and feed the root system with mineral fertilizers.

Why anthurium dries up

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 out 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 advisable to feed the plant with mineral fertilizers.

In the case of correct and timely actions, problems such as "anthurium leaves dry" are usually solved, but there are options when the cause is infectious septoria and anthracnose, the methods of dealing with which are not non-infectious and will be described below.

Did you know? Anthurium is quite difficult to tolerate an excess of moisture in a pot, however, as a representative of tropical plants, it is practically dependent on spraying over the leaves. To this end, professional flower growers recommend at least once a month to put a flower under a small pressure of the shower, and then gently wipe the dust from the leaves of the plant.

Yellowing leaves (chlorosis)

Answering the question why anthurium is sick, we can definitely say that the main problem is growing conditions and improper care. Chlorosis, which causes spots on anthurium leaves, is a consequence of a violation of the microelement composition in the supplied water, soil and fertilizers.

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

• inconsistency of the soil and lack of drainage system, which interferes with the free access of oxygen and water;
• high chlorine content in water;
• excess natural light;
• the presence of drafts;
• excessive watering or watering with insufficiently warm water;
• infectious diseases of anthurium.

It follows from this that the anthurium withers due to the banal problems inherent in other house plants. Treatment - creating proper conditions for keeping anthurium, providing irrigation with settled water, as well as regular feeding with mineral fertilizers.

Important! The root system of anthurium is very sensitive to a sharp change in the content of minerals and other substances in the soil, so it is extremely important not to overdo it with flower fertilizer. In order not to harm the plant, you should carefully follow the instructions on the packaging of a particular fertilizer for home flowers.

Leaf spot (burns)

Violation of anthurium care at home in some cases contributes to the appearance of some kind of 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;
• planting in poor-quality soil, with a lack or low content of minerals;
• improper watering;
• hypothermia.

Did you know? The soil for such flowers, that is, plants from the tropics, must necessarily contain multicomponent mineral mixtures. This is due to the nature of the tropics - in real, and not at home, anthurium receives sufficient nutrition from environment. The flower soil offered in stores also contains the necessary components, but they are all of a chemical nature and are obtained in production.

Vegetable Enationmanifested by the fact that the anthurium withers, its leaves acquire an ugly shape and are often disfigured by growths. The nature of such a non-communicable disease is not fully understood, but it is absolutely certain that problems of this kind arise after a sharp change temperature conditions content. Enations can be cured only by creating favorable conditions, proper care and regular fertilization of the flower.

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

The variety of infectious diseases is amazing, but do not be afraid and give up, since almost every one of them can be easily defeated on your own at home. The main thing is to understand why anthurium leaves turn black, flowers fall, spots and other problems appear.

Septoria and anthracnose

Septoria anthurium, like anthracnose - fungal infections, appearing as spots of red and brown. With such diseases, the tips of the leaves often turn black.

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

If there is no effective result within a week, the flower must be destroyed and the pot treated chemical compounds and high temperature.

Gray rot

An infectious disease of this type begins its spread with damage to the stem and shoots of the flower, gradually spreading to the leaves. In a short time plots plants affected by gray rot die off, therefore, the treatment of plant gray rot should be started immediately.

As a rule, experts recommend resorting to the use of chemical compounds, completely refusing folk methods, referring to their low effectiveness 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. In the absence of a proper result, the plant should be destroyed and the pot disinfected.

When pus appears in the root system of the flower, its leaves lose color, and then begin to fade rapidly. In the early stages of such an anthurium disease, it is necessary to reduce watering, increase the air temperature in the room.

In case of severe damage, the root system is treated with fertilizers, transplanted into another soil, removing infected roots.

Fusarium

Fusarium is a type of plant fungal infection. Influencing the flower anthurium, fusarium provokes rapid wilting and shedding of leaves.

By now effective way there is no treatment for fusarium, therefore, the infected plant should be immediately removed from other domestic plants, and if there is no effect from feeding with multicomponent mineral mixtures, it should be completely destroyed.

The pot, after a plant infected with Fusarium, must be carefully treated with high temperature and detergents.

The manifestation of rust on the leaves of anthurium is an invariable sign of the infectious disease of the same name. Problems of this nature are eliminated by carefully processing the sheets with chemical or alcohol solutions.

In this case, you must first remove the infected sheets. This treatment should be carried out every three to four days for two weeks.

Important! During infectious diseases of flowers, watering by means of a sprayer should be completely abandoned, since in most cases it is the water that contains the bulk of the infections.

downy mildew

downy mildew- an infectious disease that affects most domestic plants. A plant becomes ill when it is exposed to a changeable temperature, as well as a sharp change in the level of humidity in a short period of time.

The disease is manifested by the appearance of spots, as well as a sharp deterioration in appearance. Spots on anthurium leaves are most often the influence of downy mildew. This problem is solved quite simply - by timely fertilization of the soil and the creation of greenhouse conditions.

Anthurium pests, ways to deal with them

Often, the causes of anthurium disease are certain types of pests that in one way or another affect the root system of a flower, its trunk, and leaves. Anthurium, like other domestic flowers, is most susceptible to aphids, scale insects, mites and others.

Aphids, despite their small size, quite often cause significant damage to the plant.

Settling on the lower surface of the leaf, aphid begins to subscribe with the juice of the flower, provoking its rapid drying. The reproduction rate of this pest is very high, which is why it is important to respond in a timely manner and begin treatment.

Like other pests of anthurium, aphids are eliminated quite simply - just buy a ready-made preparation and treat painful surfaces with it.

Important! A day after treatment with the chemical composition of the drug, the leaves of the flower should be thoroughly washed with plain water. This is done in order to prevent the formation of chemical burns.

The scale insect can also be considered one of the most dangerous types of pests. Like others, scabprecipitates the leaves and stem of the flower and feeds on its juice. Due to its small size, the scale insect is well camouflaged on the dark trunks of anthurium, and therefore it can be quite difficult to detect it with the naked eye.

If you still managed to find this pest, you should immediately take action. First of all, the infected flower is isolated and washed with warm water.

After these procedures, you need to carefully treat all the surfaces of the flower with purchased or self-prepared compositions. As in the case of treatment from other pests, after a day the plant should be thoroughly washed with warm purified water. This procedure is repeated twice.

Did you know? The composition offered by specialized stores for treating home plants from pests, as a rule, has a multicomponent structure, which allows it to effectively act on any pests. However, the usual soap solution, which can be easily prepared at home, just as easily and quickly kills aphids, scale insects and mites.

Mealybug

Chervets- one of the most simple and noticeable pests. Already from the first days of its settlement on the plant, the surface of the leaves is covered with a white coating, which makes it possible to detect a worm.

Along with other pests, it feeds on the sap and surface layer of the plant, which undoubtedly destroys the anthurium. Fortunately, mealybugs can be dealt with by simply treating them with a soapy or alcohol solution and then rinsing off with warm, filtered water.

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

- the most difficult pest to eliminate for anthurium, however, as for other flowers. This is due to the fact that the tick hides well and, weaving a web for itself, is protected from external influences.

So, just washing off the spider mite will not work, and the use of the usual means of processing will not give the proper result. Settling on the leaf and trunk of the plant, the spider mite methodically destroys its surface, feeding on the juice and minerals of the flower.

Moreover, the tick differs from a number of other pests in the habit of destroying not only the leaves, but also the flowers of the plant, which is undoubtedly more serious and unpleasant.

Despite the apparent severity of the spider mite, methods of influencing it still exist. So, the pest does not tolerate high humidity and low temperatures. In view of this, the flower should be practically soaked in water, but immediately after that, the soil should be almost completely dried, otherwise the anthurium may get a non-infectious disease.

Important! In some cases, experts recommend treating the anthurium with potent chemical compounds, which allows you to quickly and effectively cure the plant from any pests and infectious diseases. It is important to remember that in such compositions there may be components that are equally dangerous for both pests and humans, and therefore the treatment should be carried out as carefully as possible and with the use of personal protective equipment.

Growing anthurium at home is a reverent process that requires compliance with the rules and recommendations.

The occurrence of problems and diseases, of course, is possible, but do not despair, because the simplest and most understandable methods can kill anthurium pests. And, most importantly, remember - any costs and experiences will more than pay off with the impeccable appearance of tropical anthurium.

Anthurium is special and very beautiful flower that will delight you regardless of the time of year. It blooms beautiful flowers red, pink, white and purple hues with a waxy surface.

However, anthurium is a plant that requires careful care, like any other indoor flower. Most common problem- these are anthurium diseases associated with its leaves. How they manifest themselves and how to treat them, we will consider below.

What does anthurium look like: photo

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

Anthurium is very popular among amateurs and professional flower growers. It looks unusual in itself, and it can also be used in different ways in different flower arrangements and bouquets. If you wish, 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 owners a lot of trouble. Most flower growers believe that it is better to prevent them than to treat them in fact.

Causes of yellow leaves

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

Leaves turn yellow for reasons such as:

• problems with care;
• chlorosis;
• sunburn;
• freezing of a flower;
• other diseases.

If you notice that the leaves of the anthurium have begun to turn yellow, then pay attention to how you water it, maybe not enough water or it's too hard. It may also be due to insufficient fertilizer or lack of sunlight. As a treatment, you just need to revise the watering schedule and rearrange the pot.

Diseases with yellowness and treatment

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 veins is preserved, and the leaf turns yellow. Anthurium will also need more light.

Leaves may also 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, they themselves then begin to twist and eventually dry. The best treatment in this case, there will be a rearrangement of the flower for some time in a darkened place.

You can not put the anthurium in a draft and use very cold water for irrigation. In this case, it may freeze, due to which small white spots will appear on the leaves. In such cases, they need to be moved to warmer places.

In addition, yellow leaves can signal the presence of fungi. We will talk about them a little later.

Why do anthurium leaves turn black?

Anthurium leaves can change color due to improper care. Brown spots 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 are a sign of improper plant transplantation. It is best to use a substrate for bromeliads or orchids, which will allow the flower to fully grow. It includes soils such as:

• coniferous;
• turf;
• sheet.

It also contains a mixture based on sand.

In addition to unsuitable soil, the cause of darkening of the leaves during transplantation is root damage, there is always a risk of damaging it, so read carefully in advance how to do it.

Sometimes diseases of the root system and anthurium flowers occur due to strong temperature changes. Brown heel and holes along the edges lead to the death of the plant, and there will simply be no time to treat. Therefore, it is better to take care of it properly in order to prevent this from happening.

What most often affects anthurium leaves?

To immediately remove a diseased plant from a healthy one, in order to avoid infection, it is necessary if there are such symptoms:

• specific spots;
• plaque on the leaves;
• dryness on both leaves and stems.

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

Most common fungal diseases Anthurium is:

• sooty fungi;
• gray mold;
• soil fungi;
• rust;
• and rot.

Fungal diseases of anthurium and their treatment

A disease such as rust mainly affects the stem and leaves. At the same time, brown spots of different sizes appear on them. Then the leaves may fall off entirely, and the plant will rot. This can happen if the air and soil are too dry. For treatment and prevention, wipe the plant with a Bordeaux mixture, and tear off and burn rusty leaves and shoots so that other plants do not become infected.

sooty mushrooms most often appear on the sugary secretions of aphids. They infect leaves, stems and young shoots of anthurium. Because of this disease, the plant cannot produce more shoots and its reproduction stops. In this case, it is necessary to treat the plant by cutting off the affected areas and treating the entire flower with potassium soap. It is it that will remove the resulting raid.

powdery mildew can be determined by white bloom, although it is divided into false and real. Treatment in this case in both cases occurs with the use of fungicidal preparations.

This disease appears due to the following factors:

• high humidity at high air temperature;
• sudden changes in temperature;
• care problems.

soil mushrooms provoke rotting of the hearths, they can appear when the plant is transplanted into infected soil, and also due to very abundant watering and poor drainage in pots. It is necessary to remove the affected parts of the anthurium in time and immediately treat the plant.

Gray mold is characterized by a touch of gray on the leaves and flowers. It is typical for young and weakened plants and appears due to keeping in unventilated rooms, abundant watering, poor drainage and the fact that dry and dead parts were not removed in time.

Other common fungal diseases of anthurium include:

• fusarium;
• gommosis;
• caescospore fungus.

The last disease is not as dangerous as the others, but it is strong spoils the appearance of the plant, and paints its leaves first in yellow, and then in dark shades.

• thrips;
• scab.

It is very difficult to fight with a shield, since armored bugs are not visible at the initial stage of the disease. Only with careful care can the disease be cured. Bugs can bring the plant to wilting and death, so if you notice them, you should immediately apply insecticidal preparations and do mechanical cleaning of the plant.

Thrips can be identified by black dots on the back of the leaves. They can appear regardless of the time of year, but they are especially active in spring and summer. For anthurium, both adults and larvae are dangerous. For the purpose of treatment, the flower is isolated from healthy ones and treated with an insecticidal solution. For the purpose of prevention, you should properly and regularly care for the plant and constantly ventilate the room where it is kept.

Enough dangerous and spider mite, when it is detected, you need to prepare for a long treatment process. The first sign of the disease is a thin web that envelops the leaves, stems and flowers. Then they dry up and curl up.

Treatment will be like this:

• we clean the anthurium from the web;
• wipe the pot and the surface on which it stood;
• wipe the plant with laundry soap.

Remember to keep your plant in right conditions, temperature and humidity must be optimal for its existence. The tick may return if care is started..

Anthurium diseases are better, of course, to prevent than to treat after the fact. In addition to observing the conditions of the plant, you need to constantly inspect its leaves, flowers and stems for the appearance of spots and larvae on them, and also pay attention to the change in the shade of the leaves.
