Orchid disease white bloom on the leaves. How to save orchids? Orchid diseases and their treatment

Orchid - beautiful and spectacular indoor plant. But if it is not properly looked after, then various pests or diseases can appear on it. Advanced diseases of orchids can lead to the death of the plant. And so that it does not die, it is necessary to identify diseases and pests of orchids in a timely manner and begin treatment.

Before you start pest control, it is worth determining their variety. Various pests require special preparations for destruction, so beginner gardeners should be able to identify pests on their own.

This dangerous view the pest infects orchids. The pest itself looks like a small one fluffy ball oblong shape, which has a long antennae. It usually lives in the axils of leaves near the ground. The pest feeds on plant sap. Because of this, the leaves of the orchid begin to turn yellow, and all parts of the flower become lethargic. home flower immediately separated from other plants, otherwise all indoor flowers will be affected by this pest.

To get rid of this insect, you must carefully examine the entire flower. All damaged leaves must be removed. If these pests of phalaenopsis orchids are found, then they should be collected and destroyed. The orchid needs to be dug up and the roots inspected, all damaged roots should also be removed. Destroy all old substrate. The new substrate must be treated with fitoverm, it is used according to the instructions. If there are damages on the leaves, then it is worth processing them. soapy water. For the solution you need to prepare warm water and dissolve in it a large number of grated laundry soap.

The flower is kept in quarantine for a month, and every day it is necessary to carefully examine the plants.

Shield and false shield

Spider mite infestation can be identified by a white coating on the leaves of the plant. White spots on orchid leaves at first have a small diameter, but then turn into one large spot. The tick feeds on the cell sap of the orchid. Before spraying the plant with a special preparation, it is necessary to manually remove most pests. You can clean them off with a damp cotton swab. The substrate must be replaced, and the pot itself must be thoroughly rinsed.

It is worth treating the plant twice with special preparations.

This pest looks like a small butterfly white color. It can live on all parts of the plant. The larvae are deposited on the roots or leaves of the orchid. All of them feed on the juice of the plant, which leads to a weakening of the orchid. And a weakened orchid begins to fall ill with various diseases.

Larvae and adult butterflies can be destroyed with a soapy solution. A large amount of laundry soap dissolves in water. You can also use Fitoverm.

Thrips: features

These pests most often settle even before the acquisition of the plant. Thrips are small black beetles that live in the substrate. But they feed on young roots and leaves. They move fast, it is not easy to catch them manually. Therefore, immediately after the purchase, you must get rid of them. The flower pot must be lowered into the water. Thrips cannot live in water, so in 10 minutes they will come to the surface.

Nematodes - inhabitants of the roots

These small worms live inside roots and stems and feed on juices. The plant loses vital substances and gradually dies. If there are few nematodes, then you can soak the pot or water the plant with a solution of Decaris or Levimisil. But if the lesion is severe, then it is worth pulling the plant out of the pot, cleaning the roots from the substrate and soaking the entire plant in this solution.

Leaf pest - aphid

These pests are easy to spot. First they settle in reverse sides leaves. They multiply rapidly and fill the entire plant. In places of settlement, aphids leave sticky secretions. To begin with, it is worth removing all pests with your hands. If individual parts are severely affected, then these areas are removed.

Then the whole plant is treated with Aktelik or Decis. Re-treatment must be carried out in a week.

Orchid diseases and their treatment

The plant can be subject to various diseases. They require different treatment.

Phalaenopsis orchid diseases and their treatment:

• Bacterial. Most often, such diseases affect injured plants. Synthetic antibiotics are used for their treatment.
• Fungal. These diseases can appear as a result of improperly selected temperature and water regimes. Exactly high humidity leads to the growth of fungal organisms. Treatment is usually carried out with the help of fungicides.
• Viral. Usually appear under unfavorable growing conditions for orchids. It is extremely difficult to determine such phalaenopsis diseases at home. Treatment is carried out by changing the growing conditions.

Phalaenopsis can be affected by various diseases, most often they occur due to the general weakness of the plant. Most often, phalaenopsis orchids are affected by diseases due to:

• Wrong watering.
• Insufficient ventilation.
• Pest infestations.

Phalaenopsis orchids are most commonly affected by this disease. Fusarium appears if the plant is kept at high humidity air, but ventilation is difficult.

The leaves of the orchid first turn yellow, then they begin to curl, and a pink coating forms on the surface.

How to treat an orchid? If Fusarium orchids are suspected, treatment should be started immediately. It is necessary to use the drug Fundazol. It is bred according to the instructions and the orchid is processed. You can immerse the plant completely in this solution. For a full recovery, you need to process the orchid daily for two weeks. It is also worth making sure that the roots are ventilated.

This disease appears when high rates humidity, low air temperature, using the wrong substrate and too abundant watering. First of all, it is worth using a light substrate, if it is too dense, then the airing of the roots is difficult and the roots experience discomfort.

The disease begins with blackening and rotting of the roots. Through a transparent pot, the onset of the disease is quite easy to detect. The roots completely rot, the flower lacks nutrition and the leaves turn brown.

Treatment begins with an examination of the roots. All black and damaged roots are removed. And the remaining roots should be treated with a fungicide solution. The substrate is better to take a new, high-quality. But if you have to use an old substrate, then it must be treated with a solution of Fundazol. The entire pot is completely lowered into the solution for 10 minutes. The plant itself should be processed three times. Between treatments it is necessary to maintain an interval of two weeks.

Gray rot appears due to the high dampness inside the pot and the low temperature in the room. Appear on flowers dark spots and the whole plant becomes sluggish. The disease develops quite quickly, and the orchid dies.

A good prevention of gray rot is the use of Kendal. It enhances immunity and protective functions of the flower.

The flower should be sprayed with a fungicide solution. If gray rot recurs, then the previous preparation cannot be used. It simply will not work, gray rot is resistant to such drugs.

anthracnose disease

First of all, small spots appear on the leaves of the flower. Then the spots on the leaves of the phalaenopsis orchid become larger and merge into one spot. The stain turns black. An infected flower should be isolated from the rest, otherwise the disease will spread to all plants.

To prevent the disease, it is necessary to ventilate the room well, create air humidity in the range of 50-60% and make sure that water does not stagnate in the axils of the leaves.

Large lesions are cut out with a sharp knife. The rest of the plant should be treated with a solution of fungicides. And it may take several treatments.

When defeated bacterial disease orchid leaves become lethargic, and cracks appear on their surface. Wet black dots and spots may also appear on the leaves. This disease is easy to cure.

First you need to remove all damaged areas and stains. For this use sharp knife and carefully cut out the damage. All sections should be treated with a disinfectant. For example, alcohol tincture iodine or charcoal. Some experts recommend using cinnamon or ground pepper, they will also disinfect the cuts, but will not harm the flower.

If the damage is severe, then it is worth using a fungicide solution. If bacterial spot does not appear within two weeks, then the flower can be considered healthy.

Disease prevention

In order for the plant not to be affected by pests and diseases, it is necessary to correctly organize the conditions and care. It is more difficult to cure a disease than to prevent a home flower.

Conditions for disease prevention:

• After acquiring a new plant, it is necessary to keep it for about one month separately from other plants, otherwise all flowers will get sick.
• Periodically, it is necessary to inspect the plants, check for pests, damage to leaves and flowers, and the condition of the roots. At the slightest suspicion, the flower should be placed in a dry room separately from other plants.
• Phalaenopsis orchid loves high humidity, with insufficient moisture, the plant can get sick.
• Lighting must be continuous. IN winter period you can increase the duration of daylight hours with the help of phytolamps.

Phalaenopsis orchid - very beautiful and showy plant so it needs to be taken care of properly. Moreover, competent care will help to avoid the appearance of pests and diseases.

Even with caring care for indoor flowers, they can get sick. Phalaenopsis orchids are no exception. They often get sick, as it seems to us, with rather careful care on our part. But it's not. Only violations of the rules for growing a beautiful orchid lead to disastrous results. We will analyze the diseases that are common in the Phalaenopsis orchid and their causes, as well as talk about methods of treatment.

Why do Phalaenopsis orchid leaves turn yellow and what to do?

• if Phalaenopsis stands on a sunny windowsill, its leaves can get sunburned;
• if the flower stands in the back of the room, far from sunlight, its leaves will stretch, become lethargic, lose turgor. Therefore, it is important to guess where the flower is most comfortable - there and organize a place of residence for Phalaenopsis.
• if you do not protect it from drafts when ventilating the room;
• if the pot is in the way of air flows from the air conditioner;
• if you keep it long time at low temperatures;
• if you over-moisten the substrate, the roots may lack oxygen and begin to rot. Leaves turn yellow and fall;
• sometimes, with frequent abundant watering, brown spots soaked in water appear on leaves, stems or flowers. Over time, they increase and merge into large spots. In damp, warm weather, pink, gelatinous masses of spores appear in the centers of these lesions. These are the characteristic signs of the disease called Anthracnose. Treatment begins with the removal of diseased areas from the plant, then the treatment of sections with crushed coal or iodine. For more confidence, treat with Mycosan biological preparation or copper-based fungicide;
• with bacterial or fungal infections, spots appear on the leaves different color, sometimes weeping. Bacterial leaf spot is especially dangerous. It is necessary to cut off all the affected parts of the plant. Treat slices with crushed activated carbon or iodine. If within 10 - 14 days new spots do not appear, the treatment can be considered successful. At the slightest doubt, treat the orchid with Mikosan, and the substrate with a 0.2% solution of Previkur.

Phalaenopsis Orchid Diseases

Consider some diseases and their causes.

Fusarium

1. If you use soil that is not suitable for orchids as a substrate, if you often waterlog this substrate, if the roots are constantly in heavy and not drying soil and do not receive enough oxygen and sunlight, then your flower may become infected with a fungal disease called Fusarium.This is a very dangerous disease that has no cure. The plant will have to be destroyed along with the pot.

   

   root rot

2. Phalaenopsis roots rotted, what to do? In a humid and warm environment with frequent and abundant watering, the Phalaenopsis root system rots. The lower leaves of the plant also suffer. This disease is called root rot. The rosette of leaves turns creamy yellow and the other parts turn brown. Sometimes porcini mushrooms can be found on stems, pseudo bulbs and leaves. If the disease is detected early, cut out the affected areas with a sterile instrument and treat the wounds with a fungicide. To prevent recurrence, move Phalaenopsis to a cooler, dry place for a while after treatment. If you missed the onset of the disease, and the disease has spread widely throughout the flower, then the chances of saving it are slim.

   

   Hives

3. If there is stale air in the room with a flower, if you rarely ventilate it, then there is a danger of a viral infection called Urticaria.
4. Sometimes appears on Phalaenopsis leaves brown spot. If it is not sunburn, and your orchid is not standing in the sun, then this is possibly dangerous bacterial disease. At first, it appears as a small blister spot on the leaf, which gradually turns brown and forms a bacterial fluid. Once you find the stain, cut it out with a sterile sharp instrument. Process the sheet with damaged area cinnamon or crushed charcoal. If you do not detect this disease in time, it will spread to the entire crown and the plant will die.

   

   black rot

5. Sometimes, when the humidity and temperature are too high, individual parts of the Phalaenopsis turn black like coal. The disease begins with the leaves, then the shoots and roots turn black. The disease is called Black Rot. Remove the affected areas, then treat the plant, especially its cuts, with a suitable fungicide.
6. Other viral infections can infect Phalaenopsis with improper care, for example, Cymbidium Mosaic and Odontoglossum virus. They are very similar, but various diseases orchids. The first appears on the orchid flower in the form of stripes or spots on the petals, and the second affects the leaves. They become stained, discolored and deformed. If your sick Phalaenopsis has similar symptoms, we advise you to get rid of it as soon as possible, along with the pot, so that the infection does not spread to other flowers, as these viral diseases incurable.
7. In too wet room when, after spraying or watering, moisture remains in the axils of the leaves and on the petals of the flowers, small black or light brown spots appear on the buds and flowers. It's evolving fungal disease- Botrytis. If left untreated, the buds will eventually wither and fall off. It is necessary to carefully cut off the affected flower with a sterile tool, and treat the cut with a fungicide. To prevent the spread of the disease, remove all wilted flowers from the plant on time. And gently spray the blooming butterfly orchid. Drops of water left on the flowers contribute to the emergence and spread of Botrytis disease.

   

   Gray rot

8. If small watery spots appear on the buds and flowers, which then turn into dead brown patches, your Orchid has contracted the Gray Rot disease. Along with the flowers, Phalaenopsis leaves also suffer. They appear on them gray spots with an ashy coating inside them. This plaque is easily erased with a finger. The cause of the development of Gray rot can be any of the following:

• incorrect mode of watering and spraying Phalaenopsis during flowering;
• lack of lighting;
• too much low temperature in room;
• too high ambient humidity;
• lack of ventilation;
• high concentration of fertilizers in the substrate, especially its nitrogen part;
• water unsuitable for watering orchids.

Healthy and strong plants Gray rot never strikes.

If Phalaenopsis disease is suspected, isolate the flower from other plants. Remove the affected parts of the plant. Treat the flower with some fungicide. Correct the errors in its content.

Phalaenopsis orchid pests

Most often, Phalaenopsis is attacked by such insects - pests such as thrips, spider mites, shields, . They feed on the sap of the plant, disrupting the process of photosynthesis in the tissues of the flower. The stems wither, the buds and leaves of the Phalaenopsis wither and fall off.

Thrips on Phalaenopsis leaves

Shchitovka on Phalaenopsis

All phalaenopsis are elitist. They grow in nature large trees, stumps of plants as a support. The flower has one stem, no branching. Its height reaches 10-100 cm. Orchid leaves grow slowly, as does the stem. In a year, only a few green leaves may appear. They are formed during the flowering period. It lasts 3 months. At first, the upper buds open, while the lower buds are still being formed.

How are diseases different from pests?

Reference. Phalaenopsis diseases are a common phenomenon, the main cause of which is not proper care. Diseases can be fungal, viral, and rot is also common.

Each of them has its own symptoms that allow them to be distinguished from. Most often, when a flower is affected by a disease, the leaves darken almost instantly, dry out and fall off (you can learn more about leaf diseases). And when the plant was visited by insects, then this whole process occurs gradually: the leaves become stained, slowly fade, and only then fall off. This allows the grower to react in time and save the flower.

The most common diseases of phalaenopsis include:

What are the reasons?

The following reasons can affect the development of the disease in an orchid:

• Violation of the light regime. Phalaenopsis belongs to the shade-tolerant types of orchids. They feel comfortable on windowsills facing north.

  Note! The sun's rays are dangerous for them, and if they directly penetrate the leaves, thermal burns can develop. They do not cause significant harm to the plant, but leave behind ugly spots.

• Wrong watering. The orchid prefers high humidity, but reacts negatively to constant watering water. As a result, rot and leaf fall may occur.
• Low temperature. At home, the orchid has little chance of freezing. Most often this happens during the transportation of her from the store or moving. Affected areas become covered with white spots and die off. A similar effect can occur when spraying a plant at low temperatures and as a result of poor ventilation.

How to determine what happened?

The difficulty in making a correct diagnosis is that some external signs similar to pest symptoms. So to make a final diagnosis, you will have to carefully examine the flower.

If not only the symptoms of the lesion were found on it, but also insects, then most likely they are the cause of the problem. In addition, you need to know the main symptoms of common orchid diseases. Then it will be possible to understand for sure whether it is a pest or a disease.

What parts of the plant spoil?

Most often, the defeat is applied to the leaves, roots and stem of the plant. The leaf plate begins to turn yellow, wither and dry out. The stem is darkening and rotting. root system most often affected by rot, as a result of which its roots rot and die (read how to care for orchid roots).

Characteristics of problems, photos and treatment

View photos of each disease and its description.

This fungal disease, which is formed due to high humidity and stagnant water. As a result, burns form on the leaves of the plant.

To combat the disease, it is necessary to remove all affected areas to healthy tissue., and then sprinkle them with ash. If the lesion is massive, then the plant will have to be completely treated with Mikosan preparations. Install the orchid in a dry room and constantly drain the water from the pan.

The main reason for the development of the disease is care errors. The defeat is applied to the leaves of the plant.

To combat the disease, cut off diseased areas, sprinkle cut areas with powder activated carbon. A 20% alcohol solution can be used for disinfection. If the lesion is too extensive, use Mikosan, Skor or Ridomil.

High humidity and temperature can affect this disease. You can recognize the disease by a whitish coating on the leaves.

When the first signs are found, water the orchid thoroughly, and after 2 hours, treat it with a solution of colloidal sulfur using a spray bottle. You can also use Fitosporin. They spray the leaves 3-4 times with an interval of 10 days.

You can use folk remedies, for example, a soap and soda solution. To prepare it, take 25 g of soda, 5 g liquid soap, 5 liters of hot water. Dissolve baking soda in water first, then add soap. As soon as the solution has cooled, then spray every 7-10 days.

This disease affects the leaves of the orchid, which become sticky (read about sticky leaves in phalaenopsis). The resulting black coating prevents the leaves from receiving sunlight in required quantity so that the plant weakens.

For treatment, the drug Mikosan, Ridomil, Topsin-M, Skor is used. Folk remedies are powerless here.

Black

She is one of the most common. The first manifestations of the disease are observed 12 hours after the lesion. Young shoots are most often affected. They turn black and become covered with a sticky coating.

Important! If black rot is found, it is necessary to isolate the diseased plant from the healthy one.

The transmission of a harmful fungus occurs by contact, so the treatment is difficult. Its essence is that you need to remove the affected areas, and treat the cut points with a defect of cinnamon or sulfur. After they dry, treat them with a fungicide.

Watch a video on how to cure Phalaenopsis from a fungal infection on the neck:

Root

This is a bacterial disease that is formed at high humidity and temperature. The orchids begin to darken and rot the roots. At the same time, the leaves acquire a specific brown tint.

Resuscitation of the roots should begin with treating the plant with a fungicide solution and removing the affected areas. The soil is also processed. To do this, use Fundazol or Topsin. Processing should be carried out at least 3 times with an interval of 2 weeks.

We talked about the treatment of this root disease, take a look at how this problem looks in the photo:

Gray

This the disease is the result of a violation of the rules of care. With the development of gray rot, spots appear on the flowers. They are dark in color, and then covered with a gray coating.

Note! If left untreated, the plant will weaken and die.

Treatment is reduced to the removal of affected areas and the treatment of fungicides. If after the first treatment there is no positive result, then a similar preparation cannot be used, since the gray rot pathogen has acquired resistance to it.

You can learn more about gray and root rot.

Urgent resuscitation at home

What it is?

urgent resuscitation- these are therapeutic measures that allow you to save plants in short time and prevent orchids.

When is it required?

On a note. The main sign by which you can understand that the flower will die soon is the presence of dry and sluggish leaves, a dried peduncle.

If 1-2 leaves have dried up below, then this phenomenon is normal. But when this process is extended to the entire sheet plate, urgent measures must be taken. Help your orchid if it gets sick and save it from death.

How to save?

Here detailed plan how to reanimate an orchid yourself:

1. Rinse the roots, remove the affected.
2. Prepare a container, pour expanded clay on the bottom, and carefully steamed and cleaned sphagnum on top.
3. Moisten the mixture well.
4. Lay a leaf rosette and until the plant grows roots 3-5 cm long, keep it under cover.
5. For resuscitation of an orchid, it is necessary to observe following conditions: temperature 22-28 degrees, humidity - 70-100%. Lighting should be 12-14 hours a day.

To make the orchid bloom and delight for a long time bright colors, and the disease never struck her, the grower will have to observe the following preventive measures:

Phalaenopsis is a type of orchid that, with proper care, is disease resistant. But you should not relax. The florist should regularly inspect the plant, and if abnormalities are found, immediately begin treatment.

Sometimes it happens that unwanted guests - pests - settle on your favorite orchid. This can happen for many reasons, and the grower needs to know what to do in this situation to help his tropical beauty.

Consider the main pests of orchids and describe the damage they cause to the plant.

If on phalaenopsis onion mites attack they suck the juice from the roots.

Actively eat leaves:

• thrips larvae,
• slugs,
• snails,
• Caterpillars.

• Nematodes,
• spider mites,

If pests are not detected in time and not destroyed, then the plant may die.

Phalaenopsis orchid pests and treatment with photos: causes

Buying an infected plant from a store

Take a closer look at the orchid and substrate in the shop.

Attention! A healthy phalaenopsis should have dense, resilient and smooth bright green leaves. If the leaves are wrinkled or wilted, look like rags, then do not buy the culture. Do not purchase a flower whose leaves are sticky or white coating.

Infected substrate

If you take a substrate from a flower garden in the yard, then, firstly, it is not suitable for an orchid, and secondly, very often it is infested with pests. Therefore, it is better to buy bags of substrate for the store.

Transfer from another plant

Pests can crawl on from neighboring flowers.

If you have a lot of plants in the room, then the risk of harmful insects increases.

A lot of ticks, bugs drink juice from variety of plants and crawl in search of a new plant.

Don't put plants too tight on the windowsill.

Major pests

thrips

Insects move fast penetrate the soil.

You can understand that thrips attacked the plants if you saw white spots and dots on the leaves, as well as a thin silver film.

Thrips are small insects with an elongated body.

If you get up at night, turn on the flashlight and light it up, then you will see thrips, which are on the surface of the substrate..

They are lay eggs inside leaves, then they hatch into larvae that eat the leaves. Spots appear on the leaves, the leaves turn brown, fall off.

Black dots are visible on the flowers, and “constrictions” are visible on the rhizome.

Nematode

These are tiny worms up to 2 mm long they feed on juice.

On the roots of a damaged orchid necrotic patches appear, then flows to the leaves and pseudobulb.

The worms lay their eggs on the underside of the leaves.. White spots and dots are visible on the foliage.

shell mite

Tiny insect with a body length of 0.7-0.9 mm, the body is dark brown or black.

females lay brownish eggs. They run very fast. They run and hide from the world.

They can crawl all over the orchid, but eggs are laid on rotten roots , on fallen leaves.

Appear in wet ground. They eat fallen leaves and do not pose a danger to the orchid.

spider mite

Spider mites can be grayish, whitish, sandy, brownish-red, yellowish, brick shades.

Not afraid of the light, are on the bottom sheet plate. Eggs are laid on green leaves.

Spider mites live in large aggregations on bottom surface leaves.

They are noticed by a silvery coating, similar to a cobweb, which the pest leaves on the foliage.

Yellowish, white or black spots are visible on the leaves.

Aphid

Aphids can have many shades, they can be yellow, black, orange, pink, gray, green, white. Most pests translucent.

Their body has the shape of an oblong oval 0.5-2 mm long. The female, which has 2 pairs of wings, is larger than the wingless female.

You can see insects bottom of leaves.

When the aphid breeds, feeding on juices, the top of the orchid is deformed, yellowish spots are visible on the foliage.

Place a piece of cucumber or apple on the ground as a bait and see if anyone crawls out to eat the piece. To prevent mold on the soil, remove a piece in the morning.

Woodlice, snails and slugs can only be found at night.

You can put a saucer by pouring dark beer into it. Get up at night and try collect slugs by hand. It usually takes a week for new snails to hatch from eggs, so keep baiting.

Podura in the substrate

Podura reminiscent of tiny caterpillars:

• whitish,
• yellowish,
• greenish,
• Silver.

Podura appears on the soil surface in early spring, feeding on various plant residues.

They have body length 2 mm, but there may be larger specimens up to 1 cm long. From the bottom of the abdomen they have a fork, with its help crawl and jump.

Fools appear if you are too pour phalaenopsis. Moisture stagnates on the surface of the substrate and silt appears.

To catch phalaenopsis podura, place in a basin of water so that the water completely covers the pot.

Then the fools will come up and you you can collect them.

Woodlice

Woodlouse has an elongated body, covered with scaly armor. The body is dark gray or yellowish-marble. She has 7 pairs of legs and mustache.

In length adult up to 1 cm. Usually wood lice crawl into the substrate after taking the orchid outside.

Woodlice often appear on orchids with improper care.

Woodlice eat young sprouts, leaves, stems, roots, holes appear on them. Woodlice afraid of water, because of this, lower the container with phalaenopsis for 10 minutes. completely into the water.

And then wash away the insects soapy water. If there are a lot of wood lice, then change the substrate, transplant the flower, after washing the roots.

Caterpillars

If your phalaenopsis is standing on a loggia, then adults butterflies can lay their eggs on it, and the caterpillars, as soon as they hatch, immediately begin to eat the green parts.

Can be used to eliminate pests spray plants with decoctions with onions, garlic, hot pepper, jalapeno, basil, coriander, wormwood, mint.

Pour the leaves into hot water. Strain before use.

If there are too many caterpillars, then take acephate and spray phalaenopsis, but remember that composition is toxic so please follow the safety precautions.

Centipedes

They have many pairs of legs.

Centipedes eat insects and do not harm phalaenopsis.

Means of struggle

Aktara

The drug destroys aphids, whiteflies, thrips, scale insects, false scale insects, soil flies. Aktar contains thiamethoxam, it completely eradicates pests.

Aktara effectively and quickly destroys pests.

Pour 4 g of the drug into 5 liters of water, and then use. You can put the flower pot in this solution for a few minutes, or you can spray the leaves and water the substrate with the solution.

First of all, it is worth saying a few words about the proper care of these plants. After all, this is the main factor in the prevention various diseases and a guarantee of good flowering.

7 major mistakes in the care of orchids

• overweight and frequent watering- this is one of the main reasons why an orchid dies. Strictly follow the recommendations regarding the water regime.
• Cold drafts in the room. Remember that they in no way replace ventilation and are not an equivalent concept.
• Too dry air in the apartment. Orchids are residents where the humidity is close to 100%.
• Hitting straight in summer period. From the midday heat, the plant must be shaded.
• Wet leaves. Spray and water the plants should be in the morning. If you systematically do this in the evening, then you will surely provoke diseases of orchid leaves.
• A source of heat nearby, namely, radiators. Most often this leads to damage to the leaves.
• Too much abundant top dressing fertilizers. It is impossible, firstly, to make them during the dormant period, and secondly, in an arbitrary concentration, strictly follow the instructions on the package.

To avoid the question of how to save orchids, adhere to these basic postulates. Otherwise, you may experience some difficulties.

Problems associated with care errors

The fact that something is wrong with the plant, first of all, we learn from the leaves. This is the most important indicator, or at least the most visible one for us.

The first signal that not everything is in order is a change in the color of the leaves. If they purchased yellow tint or turned red, then perhaps the reason is too bright sun. If the emerging new leaves have become too dark, then most likely they do not have enough light. A sign of malnutrition can be a change in color intensity, when all the greens become uniformly pale. These changes are not fatal. And if there is no question about how to save orchids, then helping the plant is simply necessary.

A more serious sign is the wilting of leaves or even their fall. The first thing to do is to carefully inspect the plant for pests. If his appearance is healthy enough, then the cause may lie in dehydration. Surprisingly, it is a fact: the same symptoms can indicate both an excess of moisture and a lack of it. When the substrate dries out, the roots of the orchid lose their source of water and, accordingly, cannot supply the leaves with it. And with an excess of moisture, they simply rot and also do not cope with their function. As a result, you get wilted or falling leaves.

Well, another most common situation is the appearance of black spots. They appear either on the entire surface of the leaf, or only at the tips. In the first case, the reason lies, most likely, in an excess of sun, and the plant simply burned, and in the second, waterlogging and drafts are to blame.

Bacterial diseases of orchids and their treatment

This is perhaps the most difficult category of diseases, because by the time signs are noticed, it is usually too late to do anything. Brown leaf spot is specific to orchids, especially Phalaenopsis. A leaf affected by this disease first turns yellow, and then acquires brown shade. Infected tissue becomes soft and covered with ulcers, from which cell sap comes out. The question arises, how to save orchids with such a disease. First of all, a diseased plant must be isolated from the rest. Areas of leaves affected by brown spot are carefully cut out, while capturing healthy tissue. Slices are best sprinkled with chopped This measure is effective on initial stage. After all the sections have dried, the plant should be treated with special preparations (fungicides). For example, "Strobi", "Vectra", "Fitosporin", etc. If the flower is damaged too much, including the bulb, then it will not be possible to help it, you will have to throw it away.

In addition to bacterial and fungal diseases, orchids are often attacked by pests. Let's consider each option in more detail.

Aphid

These are small (from 1 to 4 mm) insects, which, depending on the species, may have a green, yellow or black color. They suck the juice from the plant, so buds, flowers, young leaves and sprouts are a favorite location. In places of their greatest accumulation, a copper coating is formed, on which dark mold subsequently develops. At the initial stage, the plant should be washed with soapy water, and the buds and flowers affected by insects should be cut off. If the colonies are too large, then insecticides are used, for example, Fitoverm, Inta-Vir. Keep in mind that most often they all require re-treatment after a certain period, so read the instructions carefully and follow the safety measures.

thrips

These are very small flying insects with a yellow or black body. Most often they can be seen with the naked eye. In addition, signs of the appearance of thrips are spots and stripes on leaves and flowers of silver color. Buds affected by insects begin to deform. Their appearance and active reproduction is facilitated by prolonged drought. Therefore, it is so important to know what kind of soil for an orchid is needed and how to maintain constant moisture in it.

spider mite

A small insect that most often appears on orchids with soft leaves, such as cymbidium. Its active development and rapid reproduction is facilitated by dry indoor air and elevated temperatures. characteristic feature is the appearance of first pale, and then darkening spots, sometimes a cobweb is noticeable. Control and prevention measures are the same. Treat the plant once a week. Similarly, when a false flare appears.

Shchitovki

This is a very insidious pest. Often his abilities are underestimated, as a result, it is simply impossible to save the plant. Appearance pests resembles plaques of brown or gray color. They suck the juice from the plant, so they can be found most of all on the leathery leaves. The female adult spends her entire life immobile, protected by a wax shield. It is with this feature that it is difficult to get rid of them. The appearance of scale insects may be the answer to the question of why the orchid dries. Insects draw the juice from the leaves, as a result of which they begin to wither, then turn yellow and eventually fall off.

The main object of these pests are, first of all, weakened plants with impaired metabolism, "overfed" nitrogen fertilizers. You can get rid of the scale insect, but it will take some effort. Initially, isolate the affected orchid from other plants. Next, you should wash it with water or ordinary soapy water - this will help get rid of young and mobile individuals. There are many folk ways, but is it worth the risk and run the disease even more? Therefore, we advise you to immediately use insecticides. Treat the plant carefully, scale insects like to hide in the axils of the leaves, especially in orchids with sympodial branching.

Mealybug

These are very small insects, which seem to be covered with fluff, resembling cotton wool. They, as a rule, settle in the axils of the leaves or on their underside, on the pseudobulbs. With the formation of large colonies, the plant stops growing. Wilted leaves can also be a sign of their appearance. Very often, a mealybug can be brought home with a freshly purchased plant. Therefore, it is so important for the first few weeks to keep a new orchid, and any other flower, in isolation from others and observe. In this case, the advice especially applies to phalaenopsis. Ways to deal with mealybugs are similar to those with the appearance of scale insects.

Slugs and snails

Of course, in room conditions they are unlikely to appear. Slugs and snails are a scourge for those who breed and keep orchids in greenhouses and conservatories. These mollusks primarily damage buds and flower stalks, as well as the tips of rhizomes in orchids. Prevention of their occurrence is timely garbage collection and plant residues from greenhouses. These pests are nocturnal, so at nightfall, you can try to collect them by the light of a flashlight. But it is best to decompose special anti-slug granules.

The whole secret of a healthy plant is proper care of it. Observing the desired temperature and humidity, choosing correct soil and the location of the plant in the house, by setting a competent watering regimen, you will save yourself from many problems.
