Orchid is a beautiful and amazing flower, which appeared another 120 million years ago, while the peak of popularity was achieved only 3 thousand years ago. The birthplace of this flower is China and Japan. For the first time, this plant was brought to Europe for about 2nd century ago, and today there are over 40 thousand orchid varieties. With the help of scientists and breeders today there is an opportunity to grow orchid at home.

Phalaenopsis, the most popular hybrid orchid, is a pretty susceptible and capricious flower to different diseases. Therefore, in addition to the correct care and experience of cultivation, it is necessary to consider all the diseases of orchids and the methods of their treatment.

It often happens that phalaenopsis begins to hurt due to excessive care. Therefore, the most popular diseases are non-infectious diseases that are associated with illiterate departures. Very often, these diseases lead to the weakness of the bush, his death, or the formation of pathogenic organisms and pests.

Description of Phalenopsis hybrid

One of the most common orchid varieties is Phalaenopsis - the most popular hybrid in our country. This plant can have the most different buds of colors (from pure and white to dark blue color with different stains and splashes on the leaves). Orchids can be of various sizes, the number of leaves, and also not to have aroma.

The number of flowers on the plant Significantly depends on the state of the orchid itself, as well as the number of branching and may be in the range of 6-35 pieces on one branch. This plant can be quite successful to grow at home. Phalaenopsis has a shape of one stem with compacted leaves of different shapes and species, and there is also only one growth point.

This hybrid requires the same attentive care, as well as their other representatives. Since these types are the most common in cultivation, you need to tell more about their various phalaenopsis diseases with a description and photo.

Phalaenopsis is the variety of orchid, which is more often infected with noncommunicable diseases of the leaves. The appearance of the disease of the orchids phalaenopsis is due to illiterate care. However, there are other pests of the bush: bacterial spottedness, rot, various viruses, anthracnose, fusariosis.

Consider in more detail the diseases of orchids and their treatment, as well as photos of various diseases.

Non-infectious diseases of this plant are considered the most frequent. Often, gardeners complain that the orchids begin to yellow the leaves, and the yellow tint is starting and completely their bush. The reason for this may be illiterate care. This happens for such reasons:

Phalaenopsis, like any kind of orchid, needs good and high quality backlight. Lacking lighting can lead to a significant deterioration in the state of orchids: the flower stems are rapidly stretching up, the leaves get a pale green shade.

These plants are easier than any disease. And direct sun rays contribute to education of the yellowing of their leaves.

Orchid phalaenopsis is much less frequently infected with viral diseases. These diseases are distinguished by the manifestation of spottedness in the form of a mosaic on the petals of the buds and the leaves of the flower. This spotting can resemble the shape of lines, circles, arrows. When you saw signs of viral disease in orchid, first of all it needs to be isolated from healthy plants. Be sure to show an infected phalaenopsis specialist if there is no such possibility, then do at least a photo. In the case when your guesses are confirmed, this flower is best burned to prevent the lesion of healthy bushes.

Spottedness on the buton leaves is considered the first signal that the orchid began to hurt a fungal or bacterial infection. As a rule, it is the grade phalaenopsis undergoes a damage to a bacterial infection. Everything happens with the yellowing of foliage, which after a certain time gets dark color And it becomes very elastic. After the leaves are covered with wet ulcers, of which liquid substance flows. Salvation from this infection can be only circumcision of infected leaves, and you also need to make the placement of the place of cut slices by iodine.

There are more potent drugs, their use occurs at a highly launched stage. If two weeks after circumcision on orchids, new stains were not formed, the plant is no longer contagious, and it can not be afraid to install it with the other.

Anthracnose

It is also a fairly common disease, which manifests itself on the leaves of phalaenopsis. First manifest little rounded spotswhich through time begin to black and differ with a concave surface. After a certain time on these stains, a pink or yellow raid is manifested. The cause of anthrand is considered high air humidity, as well as long-term foundation of water in foliage sinuses.

To prevent the formation of this disease, it is necessary to periodically make the room ventilation. Air humidity in the room must be no more than 65%, but not less than 45%. It is also desirable to embroider the accumulated water in the foliage sinuses. With anthracnose damage, the infected leaves are removed, and the slice location is migrated to iodine. Processing with such means as soon, ritomyl, Mikasan is already produced at the launched stage of the disease.

Puffy dew

This is very . The disease appears in the form of a purple and white shade on foliage. Externally, the flower looks as if the plant sprinkled flour. This is pretty dangerous diseasewhich can lead to the death of the bush. The cause of education is considered a large air humidity and an elevated temperature, and this leads to a wallowing of the plant. For preventive purposes, phytosporin is sprayed.

Treatment of this disease of the orchid phalaenopsis is carried out by spraying the heat or a mixture of colloidal sulfur. But first, the plant is required thoroughly, and after a few hours you can begin the treatment process.

Rust

Rather rare disease rust too is fungal infection For orchids. This disease, as well as the above, infects the leaves from phalaenopsis. As a rule, weak bushes are subjected to this disease. Rust appears in the form of spots from within the leaves, which very soon get a redhead. It passes the union of fungi, which have a redhead, from this and the name of the disease - rust.

Methods of treatment are rather similar to those that apply to the diseases described above. Infected places must certainly remove, and cuts to handle with 25% alcohol. The treatment of orchids is carried out by means of splashing by Mikasan, soon and rititil.

Black fungi or sage

Also often infecting orchid pests. They are: Shield, Cherver, as well as TLL. This fungus is manifested in the form of a black laid On the sweet flower formations. These pests do not allow the passage of light to flower by climbing the litter of foliage.

Among other representatives of this type of pest, Cherver is the most dangerous. This insect has an oval look, and its size can be about 4 mm.

There are two varieties that Cherver has, capable of hitting Falenopsis:

• A bristly worm is a pest, which has a strongly pronounced reddish body and an oval shape with a snow-white raid.
• Citrus Cherver. This is a pest, which has a different color from orange to black, but, as a rule, pink with a distinctive snow-white raid. The greatest body size can be up to 6 mm.

Cherver is very similar to the shield, but it does not have a shield. Both varieties allocate the Pad - Sweetish fluid that protects them from various external factors. Chervets is a pretty malicious pest, and if there is no action in a timely manner to delete it, the orchid may die.

Cherver hurts the plant so much that all juice is managed from it, and at the same time adds your poison to flower. These substances weaken the bush, which leads to fallout foliage or its yellowing.

The formation of adhesive droplets and snow-white plaque on the foliage is the first sign that the Chervets began on the orchids.

He infects only weak orchids that are cultivated under insufficient conditions for this plant. Often these pests are formed on the bushes overlapped with nitrogen. As a rule, Cherver infects flowers in winter, at this time the day the day is shortening, and the flowers lack the light. Also, this pest may appear with the acquisition of a new flower. Therefore, during the purchase of orchids, it is necessary to be particularly prudent and attentive.

For prevention, a fairly popular means where is tree oil number. It is used only for prophylaxis, since the treatment of this drug will not show a positive effect.

You can also use the hot soul method. The meaning of this method is to irrigate orchids warm water 45-55 gr. Since these pests die at a temperature of more than 40 grams, this option is very effective in the treatment of the plant. The shields also often infect orchids.

Viral and fungal infections of phalaenopsis can lead to the formation of rot. Passes the process of reinforcement roots, as well as plant foliage. The reason for posting can be increased high humidity and temperature.

Treatment is the multiple treatment of roots and soil 0.3% Fundazola either 0.2% belanty mixture. It is necessary to completely omit orchid into this substance. The interval between sessions must be at least 2 weeks.

Rot

Fale phalaenopsis disease is a gray rot. This rot is manifested in foliage in the form of brown and black specks with fluffy education. The reason for the formation of rotes is considered high air humidity, and for the prevention, they are advised when watering is used to use kendale. It increases the resistance of the plant to different diseases. In the case of infection of orchids, rot, you need to conduct fungicide spraying. And with secondary lesions, they advise to use other fungicides, since the disputes of rotes are adapted to the funds used.

1. The formation of black rotting takes place on plants that are already infected with pests and diseases. In order not to destroy the plant, finally, you need to remove the affected areas and foliage, and cutting the cutting areas in colloid gray.
2. Fuzarion rotes infects the leaves of the plant, they begin to shut yellow and fold through time. Leaves get a grayish color. The treatment is made using the full immersion of the orchid at a 0.3% mixture of Fundazola. This procedure is required for 2 weeks.
3. The characteristic feature of the brown rot is considered the infection of young leaves of orchids. The rot is appearing in the form of bright brown formations, which grow very quickly and get a rich-brown tint. Wrestling methods are exactly the same as with other types of rot. And for the prevention, it is possible to spray with a slight solution of vigor not more than once in 30 days.

Summing up, we can say that at elevated temperatures and excessive humidity it is necessary to air often, not to install orchids are very dense among themselves, trace the water to be on foliage for a long time. Water and spray orchids are only necessary at the beginning of the day. It is advisable to put a fan in the room with a lot of and crowded plants and give it to work at least in the hottest time. It will be able to help prevent many problems and various kinds of diseases.

Orchid diseases

Luxurious orchids are increasingly appearing at home among amateur flower. Tropical plants They please the eye with gentle flowers, fill the room with a wonderful aroma.

Causes of appearance

Important! The earlier the owner detects the presence of the pest, the greater the chance to save a delicate flower.

Tripses

How to detect:

Danger:

Learn instructions for use, as well as about the advantages and disadvantages of the drug.

The rules for use of the means of getting bugs, as well as precautions are described by the page.

Treatment:

• wipe the leaves, remove damaged platinum;
• treat orchid composition, accility or phytodeterm. The optimal interval between procedures is 10 days, the number of spraying is three;
• every five days for the prevention, wipe or rinse with water leaves.

Mealybug

General information:

Treatment:

• crop your order on the upper layer of the soil: remove fallen leaves, dried pseudobulb;
• twice spray the lower part of the plant and the substrate with the preparation of phytodeterm. There should be from 7 to 10 days between processing;
• every morning to inspect the plant, remove adults and the accumulation of eggs, to process the affected area with clean water;
• for prevention every 4-5 days, carefully wipe the leaves, inspect the flowers, the soil in the vase;
• regularly clean the fallen leaves;
• the plant is considered healthy if for four weeks after processing there are no new features and eggs.

Pincers

Treatment:

• . Spraying with the preparation of phytodeterm. Three-four treatments with an interval of 4 days at a temperature of 30 s. Pliers love dry areas, excess moisture harm them. Will help the pallet with water, transfer the pot into the warm room with sufficient humidity;
• root tick. Be sure to remove damaged parts of the root system. Dilute phytodener according to the instructions, pour the soil, spend two spraying with an interval per week;
• tick \u200b\u200bflatwelt. As well as when combating a spider tick, increase the percentage of moisture in the room, pour water into the pallet. It will take four spraying by phytodeterm. The optimal interval between procedures is 4 days.

Shield

Treatment:

• water procedures;
• removing the shield from all parts of the plant;
• processing with accuters or phytodeter. Re-spraying is carried out in a week;
• it is advisable to transplant the orchid phalaenopsis into a new vase with a good, nutrient soil;
• every week inspecting the leaves, wipe with a damp cloth. Missing the substrate for a strong water stream monthly.

Caring for orchids

At home, the amateur flowers will have to work a lot to keep the luxurious flower. With insufficient attention to the instance, the plant will quickly weaken, may die.

How to get rid of in a private house and prevent their re-appearance? We have an answer!

Useful information on how to remove bugs from the apartment yourself read the page.

Go to and find out how to get rid of the midges in the apartment.

Fundamental rules:

• lighting. It is important to put the flower correctly: not allow direct sunlight to enter. The sufficient level of scattered lighting is required. Lack of light provokes a change in the shape of the leaves (stretched), rarely blossom. The duration of the daylight is 12 hours, if 10 hours and less - will need additional lighting;
• optimal temperature For orchids purchased in flower shops, is: day - from +18 with to + 27 s, at night - from +13 s to + 24 s;
• watering For orchids, phalaenopsis will need moderate: the soil must be wet, but too wet soil worsens the health of the plant. Stagnation of water is a dangerous phenomenon. It is impossible to allow frequent cutting of the substrate: the delicate flowers will not hold out such experiments for a long time. Water suits soft: melt, rain or boiled, be sure, for a couple of degrees above temperatures in the apartment. In summer, watering is carried out two or three times for a week, in winter, when the pseudobulb is wrinkled, less often - one or twice in 7 days, during flowering period - more often;
• fertilizers. The feeder is held once every three weeks. Flower shop sell fertilizers for orchids. It is impossible to "overflow" the plant: excess mineral salts Negative effect on growth and flowering. Mandatory care element - washing the substrate every two or three weeks. In winter and during the rest, it is not necessary to feather the soil in the vase. The researchers found out: too frequent feeding orchids reduces the immunity of the plant, increases susceptibility to disease.

It is important to know that the first time spent, gentle flowers appear at the age of orchid 1.5-2 years. For abundant, long blossoms need two conditions: The optimal duration of the daylight plus the difference between the night and daytime temperatures at 5-7 degrees. If orchid does not bloom, you can temporarily reduce the temperature in the room to +16 degrees for two weeks or decrease watering. Depending on the number flower kidney, bloom lasts from 2 to 8 months.

The pests of orchids Phalaenopsis penetrate the plant and in the ground with different ways. Protection of delicate colors, their treatment and daily care will provide long-term flowering, spectacular view of the tropical decoration of any apartment.

Diseases of phalaenopsis

Most diseases in phalaenopsis occur due to high temperatures, high humidity, and stagnant air, due to poor ventilation.
Most fabric orchids are soft as a result of proper care Various bacteria easily penetrate from the surface of the leaves in the fabric.
With proper care, the plants will become strong and more resistant to various diseases and insect pests.
Wounds on the leaves and stems also contribute to the penetration of bacteria in the tissue.

So the main diseases that may apply to the soulless damage to phalaenopsis and even lead to his death is:
(Bacteria)
First, bacteria: most often they are in the depths of plant tissues and with poor care or injury, wet water, start rapidly developing and affecting the plant.
(Fungal diseases)
Mushroom: The body of mushrooms is striking the leaves and induced Phalenopsis stem, usually penetrates the fabric during the damage to the plant or poor care (increased humidity in combination with reduced temperatures, stagnation of air)

(Viruses)
The virus is a physiological disease and cannot be treated

_________________________________________

(Uredo japanica or urticaria)
Disease, mainly occurs on the leaves of orchids, on early stage Dark brown rounded spots with a diameter of about 2-3mm appear on the sheet, then the disease covers all the plant. Diseases mainly occurs at low temperatures, wet weather and poor ventilation.
Control methods:
1. To keep dry foliage
2. In wet or cold weather, do not water at night
3. The air indoor should not be stamped.

Bacillus Cypriped or Erwinia Chrysanthemi
This is a very dangerous disease that is common on phalaenopsis. Bacterial pathogenic infection developing in warm high humidity. The affected areas are soft, brown and often smelling. The disease begins with a small stain that is quickly spreading. The leaf plate is quickly wrinkled, a slightly lighter spot around the edges, looks wet. The disease is developing very quickly - in the morning the spot is brown, the day is brown, in the evening or the next day, the whole plant is brown. This is a bacterial disease dissipated when watering and spraying.

Treatment: Quickly cut the affected parts, lubricate with fungicide, do not water! Avoid getting water to the plant and ensure good air circulation.

Dry spots or Cladosporium Orchideorum
Dry brown spots appear on phalaenopsis, gradually sprawling on the plant. The reason for the occurrence of the disease is pathogenic mushrooms developing in wet air.
Control methods:
1. Do not allow too humid environment, and attention should be paid to ventilation
2 Infected parts need to be removed to treat anti-GRIBC (Fungicide) drug.

Phytophthora Palmiala Block Rot Pythium Ultimum Black Rot
Mushroom infection, black rot, phytoofluorosis.

One of the most surround diseases of phalaenopsis. Infection often leads to the death of the entire plant. Called by pathogenic bacteria Palmiala Phytophthora and Phytophthora Parasitica.

Control methods:
1. Avoid stagnant air especially with its high humidity and high temperature.

2 If the plant is sick, remove the affected part, to be treated with an antibacterial preparation, contain in dry conditions.

Botrytis Cinerea or Botritis

More often develops in conditions of high humidity, and its grind. Dark brown spots appear on the drop-down petals. In more severe cases, the petals are faded. With an increase in air temperature, the disease decreases.
A warning:
1. Ventilation, prevent the stagnation of wet air,
2. Use bactericidal preparations.

Leaf fabric death (mesophyll collapse)
At first, uneven yellow spots appear, then the depressed points \\ stains. Robert Doyle Curry conducted a study, as a result of which came to the conclusion that these stains begin to develop during watering or spraying plants with cold water.

Damage caused by watering cold water

Fusariosis
The reason for the fusarium mushroom. As a result of its activities, the surrounding tissues are yellowing, parts of the plant are twisted.

Control methods:
1. Ensuring the air circulation of the proper temperature mode and reduced air humidity
2. Bactericidal preparations

Bacterial spot Cercospora

The disease is caused by the Mushroom Cercospora. Yellow spots appear on the leaves incorrect form Various intensity, from 5 to 10 mm. Sometimes mold appears on the bottomside of the leaves. This disease is developing at elevated temperatures and high humidity. More thermal-loving phalaenopsis, such as P.Lueddemanniana, R. Mariae, R. Micholitzii, are especially exposed to this disease.
Control methods:
Provide good ventilation. Do not water the plants at night, do not spray the plant, reduce the humidity. Sick plants put in privacy.

Phyllostictina pyriformis

Mushroom disease causing leaves. First, small yellow or black small spots remaining unchanged for several months appear. Nevertheless, at this time the development of mushrooms inside the fabric occurs. During the week, two after the development, the sheet plate dies. At the same time, a very characteristic spotted color is revealed.

Frostbite

Chlorosis

Arises because of the presence of chlorine in water. It begins gradually, and in the absence of treatment is exacerbated, then the leaves are covered with black spots, and the plant is dried quickly. Develops regardless of the type of substrate used by landing. Helps using a filter for water.

Yellow conical stains are a cymbidium virus and on the leaves on the right (the most terrible in my opinion) swelling of fiber ....

Burkholderia Gladioli.

The disease caused by Burkholderia Gladioli bacterium. Often such plants may come from Asia, often such stains are mistaken for frostbite.
Treatment: cut off the fabric to a healthy, handle with green, do not moisturize the leaves of tension during the month.

Dropsy
Refers to care errors. If you pour a plant in the heat and at night the temperature significantly decreased this problem can not be avoided. It often occurs on the windowsills of the southern and western, where the temperature of the temperature is very high and at night are significantly reduced.

Sunny burns

Orchid diseases at home, not so rarity. Unfortunately and orchids are sick, even despite the most attentive care, or rather, it is most often sick from excessive care. The most common diseases of orchids can be called non-infectious diseases, they are usually a consequence of improper care. Such diseases can lead to the death of the plant or simply weaken it, the development of pathogenic microorganisms may be the development of these diseases.

Wrong care - insufficient watering

Diseases of orchids Falenopsis

Since Falenopsis Orchid is the most popular for growing on the windowsill, we present a list of diseases that it most often is sick. Most often, this species is sick of non-infectious diseases associated with incorrect leaving. In addition, frequently phalaenopsis is amazed with viral and bacterial spots, anthracnose, rotten and fusariasis.
Below we will tell about all diseases and measures of struggle in detail.

Sheet of friths

Non-infectious diseases of orchids

So, for example, more often than newcomers sighs puzzled: yellow leaves from orchid Falenopsis or orchid Faleenopsis turn yellow? This may occur in the following cases:
- if the orchid frozen or percussioned,
- If there is an insufficient or excessive watering,
- Also, the leaves can also be yellow, both due to lack of lighting and due to sunburn. All the above applies to other types of orchids.
Very dangerous for orchids wrying the plant, it is much worse than sunburnSince in this case the overheating is exposed to all the plant, the kidneys, buds are damaged.
No less dangerous and planting the plant, however, if this phenomenon was briefly, then nothing terrible. But if this negative impact lasts 10 - 12 hours, then in some types of orchids may damage vegetative kidneys and the plant will surely die.

Plant affected by virus

If the plant lighting is lacking, the leaves become light green and elongated. Such plants are easily affected by disease diseases. With too intense solar exposure, the leaves can be covered with yellow burns of burns, and if the burns area is large, it cannot but affect the plant's condition.

Viral diseases Orchids

These diseases are quite rare, and can manifest themselves to the mosaic spottedness of leaves and flowers, small stains in the form of arrows, circles, stripes. Most often all other types room Orchids Types of viruses are susceptible to viruses: Cymbidium, Phalaenopsis, Odontoglossum, Vanda and Cattleya. If you have suspicion that the plant is sick with a viral disease, it needs to be as soon as possible from the rest and show by a specialist. And if your diagnosis is confirmed, the patient orchid should be burned, because it can become a source of infection for other colors.

Bacterial spotting leaves

Orchid - Diseases of Leaf

Spots on orchid leaves may most often arise due to bacterial and mushroom diseases.

Bacterial spotting leaves
Pretty specific and dangerous disease, phalaenopsis is amazed most often. The damaged sheet tissue is yellow, then darken, through time they become soft and covered with wet ulcers, of which the fluid becomes.
Measures of struggle:
The affected areas should be cut, and then process sections with activated carbon powder or iodine. The use of stronger preparations can only take place in the case when the share of the sheet is damaged or in highly running cases when there are many stains. The plant is considered not contagious if for 10 days after trimming the new stains did not appear. In this case, the plant can be put to the rest.

Anthracnose

Anthracnose
This disease is manifested as follows on the leaves less often on orchid pseudobulbs, small round, but clearly defined stains appear, brown color. Over time, small spots can be merged into large, these large sections are black and have an indulged surface. Next on this black may appear pink or yellowish flare.
The main reason for the appearance and development of the disease is too high air humidity, and besides that the cause can be the stiring of water on the leaves and in the sneakers of the leaves, as well as on pseudobulbach in the core.
Prevention of disease
In order to prevent prevention, it should be maintained in the air room from 40 to 70%, to periodically air the room, not allowing air stagnation. You should also remove the water from the leaves of the plant, getting it in the sinuses, and prevent the pseudobulb to get into the core.
Measures of struggle:
The areas affected by anthracnose are removed to a healthy fabric, and the sections of the sections are treated with activated carbon or ash. With a strong damage, the biological preparation of micosan is treated, or Ridomyl chemical preparations, soon and topxin-m.

Puffy dew

Puffy dew
This fungal disease is manifested as follows: the leaves and orchid letters are covered with a light white tap, as if the plant sprinkled with flour. The affected parts of the plant dry out over time, and in the end, the entire plant dies. The development of the disease, as in the previous case, is facilitated by excessive humidity and high temperature, in other words, the greenhouse effect.
Prevention of disease
For prevention purposes, it is recommended to use phytosporin spraying.
Measures of struggle:
At the first manifestations of signs of the disease, orchid need to be carefully sprayed with a solution of colloidal sulfur, or with topsin-M drugs or soon. Before spraying the plant, it is necessary to pour well, and after an hour or two after irrigation, spraying can be performed.

Rust

Rust
This disease can be found not as often as two previous ones. Rust, as well as puffy dew It is a fungal disease and amazes, first of all, the leaves of orchids. It manifests itself as: on the bottom side of the sheet, light spots appear, in which small brown choppers appear later, it begins the spraying of the mushroom. Rust, as a rule, affects weakened plants.
Measures of struggle:
The affected areas on the leaves or if the leaf lesion is very large, then the entire sheet is completely removed, and the sections of the sections are disinfected with activated carbon, chopped into the powder or a 20% alcohol solution. From finished drugs, a spraying of micosan biological preparation can be used, or Topcin-M chemical preparations, soon and readomy.

Sent (black) mushrooms

Sent (black) mushrooms
Sent (black) mushrooms, as a rule, a consequence of the lesion of the plant by pests (tool, tormentless cherberry, white shield), it is on their sweet highlights and a fungus appears. The resulting black chart clogs the dust of the leaves and prevents the light access to the plant, the plant weakens and can die over time.
Measures of struggle:
In case of damage to the plants, a black fungus is treated with a biological preparation of micosan, Topcin-M chemical preparations, and highly detected.

Root rot

Rot

Orchid, are also subject to different rotches, which are usually caused by both fungi and bacteria. Determine the causative agent of the disease Even a specialist is a rather complicated business.

Root rot
At the same time, the diseases of the roots and the leaves of the plant are discharged, they acquire a dark-cut color and become soft. Disease cause excessive humidity and high temperatures.
As a rule, the root rot is sick orchids of species Cymbidium, Paphiopedilum, Miltonia.
Measures of struggle:
When showing signs of the disease, it is necessary to carry out threefold treatment of roots and substrate by one of these solutions: 0.1% Benal solution, 0.2% Fundazola solution or 0.2% topsin solution. The easiest way to carry out this procedure by immersion, the break between procedures should be 10-14 days.

Gray Gnil

Gray Gnil
This disease is very subject to orchid species of Cattleya and Phalaenopsis. A gray rot on petals and cupboards, in the form of brown and black spots covered with a gray fluffy blooming. This disease is again a consequence of improper care if the plant has been kept in a long time in conditions of reduced temperature and high air humidity. Under such conditions, the plant weakens, which is why it is very important to follow the care instructions for one way or another.

Prevention of disease
IN preventive purposes It is recommended to use when watering the drug Kendal to increase the resistance of plants to diseases.
Measures of struggle:
In this case, first of all, you need to create favorable conditions for the content: adjust the watering mode and spraying, lower the humidity of the air, more often to air the room where the orchids are contained. With a strong lesion, it is worth spraying a plant with any fungicide, but in this case it is necessary to remember that when a sulfur-infection is re-infected with a gray rot, another fungicide should be used, as the mushroom disputes are very quickly adapting to drugs.

Black Rot

Black Rot
Black rot appears on plants already weakened by pests or diseases. The cause of the disease is fungal rot, it is subject to orchid species of Cattleya, Paphiopedilum.
Measures of struggle :
The parts affected by the rot from the orchids are removed with a sterile sharp knife or scissors, and the sections are sprinkled with wood coal or colloidal sulfur powder or treated with borobo liquid. After such a processing, the old substrate is thrown out, the pot is sterilized and only the plant is planted. After disembarking in a fresh substrate, the plant needs to create greenhouse favorable conditions, but not allowed in any case soaring.

Fusarious rot

Fusarious rot
Fusarious rotes most often amazes orchids of species Epidendrum, Miltonia and Phalaenopsis. The disease is manifested in the yellowing of the leaves, the edges of which are twisted and after time the plant acquires a grayish tint, and the central escape boosts and dies.
Measures of struggle:
To save plants from this unpleasant illness, it follows 10 days three times a day to process them by immersing a 0.2% solution of Fundazola.

Brown bacterial rot

Brown bacterial rot

This disease is striking, first of all, young leaves, they appear watery light - brown spots that quickly darken and grow in size. The disease arises due to the violation of the conditions of content: under reduced temperature and high humidity. More often, the rest suffer from this confusing orchid species of Cattleya, Cymbidium, Phalaenopsis, Paphiopedilum.
Prevention of disease
To avoid lesions, you can spray plants once a month with a slight solution of copper mood.
Measures of struggle:
When combating brown rot, the same struggle measures are used as when combating black rot.

These flowers belong to the nature of the orchid, which, in turn, belong to the class of epiphytic. Epiphyte foliage has great importance. Thanks to the leaf plates of orchid:

• support overall water balance;
• get the right amount of nutrients;
• take an active role in the respiratory process of photosynthesis;
• evaporate excess moisture.

Attention: Orchid hard plates fabrics are quite fleshy and dense, they serve as tanks for the accumulation of moisture flower, as well as useful nutrient minerals and microelements.

Why can her be a disease?

Orchid leaves are indicator of the overall state of the entire plant.. If they are externally healthy, then all other parts feel comfortable. The causes of lesion leaf diseases are:

• illiterate care;
• infection of orchid harmful insects;
• incorrect content parameters in home conditions;
• the development of fungal and bacterial diseases on the background of hypothermia or overcoat.

Step-by-step instructions for the treatment of ailments and their view in the photo

Most often, orchid leaves are infected with the following diseases that have their own characteristics and ways to get rid of them.

Anthracnose

This is a fungal disease, it begins with the appearance on the sheet plates of small spots of a rounded form. These stains start black through time. Each spot is characterized by concavity in a leaf of the plant..

After some time, a yellow or pink shade begins to manifest on these spots. The cause of the development of anthraznosis is considered high humidity or oversupply of moisture in foliage sinuses.

How to treat? Need to act according to the scheme:

1. All the affected foliage cut off.
2. Sections of sections must be treated with activated carbon, iodine or wood ash.
3. To get into the cloth accumulated moisture in the sinuses of foliage.
4. Conduct treatment with funds in which there is copper - the Vitaros, Hom, the forecast.

Spotted

Spotted leaves - this is a bacterial disease. On the leaves of infected orchids, dark spots appear, the leaves begin to shut up, darken, and after they become soft and ulcers of which are formed on them. To save the flower you need:

1. Crop all affected parts of the plant.
2. Required sections of sections to be treated with activated carbon powder.
3. Immediately carry out the processing of fungicides - soon, Topcin-M, Fundazol.

Important: If new stains did not appear after 10 days, the plant is completely great.

Lepacity

Procedure:

1. Remove infected flowers.
