There are fungal, viral and non-infectious diseases of Anthurium, affecting the plant with improper care or infection through water, soil, insects. The vast majority of diseases are easily prevented by observing basic rules for flower care. The correct irrigation regimen will help to avoid fungal infections, viral diseases are carried by pests, it is important to ensure the prevention of insecticides. It is very easy to overcome non-infectious diseases of anthurium, it is enough to provide comfortable conditions for the plant.
Causes of anthurium diseases, their treatment
Leaves turn yellow
If the leaves turn yellow during the cultivation of the anthurium, many owners do not know, but the causes of the troubles are obvious: often the problem is caused by errors in care and uncomfortable conditions, to which the flower quickly responds with a protest.
Leaf damage is a sign of a diseased flower
Conditions determining why the tips of leaves and flowers dry in anthuriums:
- irrigation in direct sunlight;
- dim light in the room;
- nitrogen bait deficiency;
- small flowerpot;
- watering with hard, too cold and not settled water.
Yellow or brown spots on the leaves of the plant often signal diseases that require surgical treatment. Waterlogging of the soil and low air temperature threaten bacterial and fungal diseases of the leaves of anthurium:
- Fusarium is introduced when changing the soil;
- chlorosis manifests itself with a lack of iron and magnesium;
- Septoria is the result of drafts, cold, humidity;
- rot forms when humidity is high, leaves may turn brown with excessive watering.
On a note! Do not forget about the natural features of the old Anthurium, when the leaves turn yellow for a natural reason. What to do? The right decision during the period of crop renewal is to reduce watering and feeding.
Why leaves and flowers turn black and dry
The following factors provoke blackened anthurium:
- Watering with cold water. The optimum temperature of the liquid used to moisten the culture is 22-26 degrees. Permissible deviation from room temperature is 2-3 degrees.
- Rotting rhizomes. The solution to the problem of why the leaves of Anthuriums turn black should be looked for in the wrong watering. Excess moisture causes the plant to blacken and die.
- Fungus on the roots of anthurium. With insufficient drainage, the flower begins to suffocate and dry out. To prevent the disease, loosen the earth and create additional holes in the pot.
- Hard water. Excess calcium negatively affects the levels of magnesium and potassium. Also decreases the percentage capacity of iron, manganese, zinc, boron. The deficiency of useful elements makes the anthurium dry.
- Excess fertilizer. The dosage should be reduced by half or temporarily stop feeding.
- Moisture deficiency. Symptoms - the leaves began to curl and darken, a change in the usual form. It is worth paying attention to spraying the crop or putting a pan with water next to it, providing increased moisture to the plant.
Blackening Anthurium Leaves
On a note! Pests are the most dangerous enemy for anthurium flower. Why leaves and flowers turn black and dry, the cause should be sought as a result of the activity of whiteflies and aphids. If the fears are confirmed, the affected areas are washed with soapy water, treated with pesticides.
Sticky leaves how to treat
Dense foliage protects "male happiness" from various parasites. But vigilance is not worth losing. With the appearance of sticky secretions on the anthurium, brown spots on the leaves, it is important to know what to do in the fight against scale insects. Usually the pest is removed with cotton swabs, the bush is treated with an actar solution - 2.5 liters of water 2 g. With a slight lesion, it is enough to wipe the foliage with a soap solution. Also, the flower is treated with "Karbofos" (2%).
Anthurium is not growing
If the anthurium does not grow what to do, the florist determines, based on the conditions of the culture, where the main factor is the location in an open and well-lit place, without drafts. Often lovers make the mistake of planting a flower. The soil is not suitable for the plant, transplantation or drainage is required - additional reasons why the anthurium does not grow.
Remember! The flower prefers plastic containers, a deep fiber substrate and does not tolerate exposure to direct sunlight. Pots for young individuals are changed once a year, for adults after 3-4 years.
Fungal diseases of anthurium, their treatment
Microscopic fungi can remain on the plant when purchased or appear during heavy watering. Anthurium is a moisture-loving culture, the probability of the spread of bacteria is highest.
Peronosporosis
The leaves of "male happiness" are covered with white, yellowish spots, gray spores are observed on the back. The source of the disease is a microscopic fungus, which is extremely sensitive to moist air. It is easy to cure peronosporosis - it is enough to reduce air humidity and treat the culture with contact-action fungicides ("Topaz", "Acrobat").
Rust on Anthurium treatment
When light spots appear on the upper side of the sheet, and brown spots-pustules on the lower side, it is likely that the anthurium began to suffer from a fungal infection such as rust. At the bottom of the leaves, spores develop quite quickly, the spots merge together, the leaves dry out. To treat the disease, fungicides are used (Albit, Alirin, Fitosporin).
Rust - A Common Anthurium Disease
Fusarium wilt
Fusariosis is transmitted in a variety of ways, including water and air. New fungal spores can grow with temperature extremes and chemical attack. Fungal wilting of anthurium produces a light pink plaque on the root neck, wilting of leaves. The main measure to combat Fusarium infection is prevention, for example, feeding the soil with the antifungal drug Gliocladin. Systemic pesticides "Vitaros", "Rovral", "Fundazol" are also well established in the fight against fusarium.
Septoria
Fungal mycosis manifests itself on leaves as red spots surrounded by yellow lines. The leaves begin to gradually fade, and the plant dies. The main treatment method is treatment of the culture with copper-containing fungicides (Bordeaux mixture, vitriol, Kuproksat).
Anthracnose
Fungal disease leads to thinning and drying out of leaves. Dry brown spots appear at the edges or in the middle of the leaf blades. Systemic fungicides (Fundazol, Acrobat, Ridomil Gold) will help in the fight against anthracnose. The spores of the fungus are quite tenacious, if it was not possible to save the anthurium, you should treat the neighboring plants with pesticides, calcine the old pot and grow a new individual in a safe environment.
Late blight
The symptomatology of the disease is the appearance of violet-brown spots on the leaves, their rapid development on the plant and damage to the roots. To kill late blight, systemic fungicides are used, including Fitosporin-M, Fundazol, Alirin-B, Previkur. Be sure to have to replace the soil, lower the roots into clean water, rinse and burn the pot. The root system is also treated with a weak solution of potassium permanganate.
Pests
Room anthurium, in addition to diseases, can dry or rot under the influence of insects: aphids, thrips, spider mites, insects, or whiteflies. When pests appear, a soap solution or an insecticide will be required, it will be necessary to process the culture once every 2-3 days.
Aphid
It is easy to find out about the defeat of anthurium aphids by yellow, twisted sheets, sticky secretions, the plant begins to die quickly. The simplest pest control measure is a warm shower or spraying the plant with a soap solution (20 g of laundry soap in 6 liters of warm water). A more effective solution will be the use of drugs: Antitlin, Aktara, Actellik.
Aphids on Anthurium
Thrips
The leaves affected by thrips are covered with bright yellow spots of various parameters and shapes. Parasites are located at the bottom of the leaves and have a brown hue. The danger of thrips is achieved by the spread of the rust virus. The optimal environment for unwanted guests is high humidity and temperature. It is necessary to adjust the climate in the room. Highly toxic drugs will help treat a flower affected by thrips: Tanrek, Actellik or Fufanon.
Spider mite
A spider mite gives out small yellow specks on the outside of the leaves, merging into huge spots. A spider web appears at the bottom of the leaf, full of small insects. Ticks love heat and dry air. As soon as the flower turns yellow, it is important to urgently treat the leaves with a soapy solution, clean from insects and wipe with mineral oil. Establish humidity and temperature.
Shield
Whitish or golden brown tubercles on the leaves of anthurium are the first signs of a scab, sucking out the vital juices of a home flower. Remove the pest from the sheet will allow a regular needle. Single individuals are also brushed off with a toothbrush, wiped with a cotton swab soaked in kerosene - under the kerosene film the shield suffocates.
On a note! Often, flower growers experiment with an oil-based spray to polish the leaves of anthurium. With the active propagation of parasites, an insecticidal solution should be made and mineral oils prepared for the treatment of greenery.
Whitefly
The flower looks oppressed, leaves are curled and discolored, buds and flowers are showered. It is necessary to carefully examine the pet, especially the underside of the leaves. Perhaps the plant has become a haven for insect pests - whiteflies. Small moths with many larvae suck out the vital juices of Anthurium. The secretions of whiteflies on the upper part of the leaf are reminiscent of a sticky shiny coating, similar to sugar streaks. When whiteflies appear, experts advise resorting to the use of chemicals: Aktara, Confidor, Akarin, Iskra, Fitoverm, Actellik, Tanrek.
Whitefly on a healthy plant
Noncommunicable diseases
Chlorosis
If yellow spots are visible on green foliage in bright light, the culture suffers from poor nutrition (lack of magnesium and iron). It is important to take care of regular dressing of the plant with fertilizers for decorative flowers.
Smallpox
Yellow-green bulges and annular yellowing are the result of low temperature in combination with high humidity. If you forget about regular feeding of anthurium, the plant will not have the strength to resist smallpox, it will take a long time to reanimate the culture.
Of enations
When a flower is infected with enacia, uneven leaf curvature is seen, an ugly and hunchbacked appearance, the anthurium may turn black. The disease progresses in cold rooms with drafts, sudden changes in dry, moist air.
How to save anthurium, if there is a stump with leaves
Luxury Anthurium chopped, rotted, and left a tree stump with leaves? You will have to use the radical method of preserving the culture: completely cut off the stems, leaves and flowers, remove the anthurium from the soil, carefully examine the rhizome for rot, peel or cut, treat with an anti-parasite agent. Transplant into a healthy soil mixture.
Anthurium requires an urgent transplant
Anthurium is a beautiful and unpretentious exotic culture. When keeping the plant at home, it is worthwhile to establish proper care for and prevention of diseases. The flower will decorate the interior for more than 10 years.
