Orchid - a flower that amazes with its beauty and elegance. But unfortunately, they, like other plants, are prone to pests. Pests on orchids do not just appear. They rarely threaten a healthy plant, but as soon as unfavorable conditions for orchids (heat, cold, waterlogging, lack of light) develop, the plant's immunity decreases and they come, pests!
The worst and most difficult pests on orchids - spider mites. There are spider mites on orchids because of the dry air in the apartments and the high temperature, it is possible that they would enter the houses through the half-open windows in the spring-summer period or with a gift bouquet. Like all other pests, mites drink the juice, which leads to the death of the flower.
Mite to detect with the naked eye will not work, in order to see them, you need to use a magnifying glass with a twentyfold increase or more. If you noticed spiderwebs on an orchid, but you didn’t find any spiders, then know that a spider mite settled on it and once the spiderweb is visible, then the damage is already serious, because the spiderweb is not visible at first. A red mite can also appear on the orchid, it is easier to detect because of the color, on the back of the sheet there will be red spots, grains or stains.
Fight ticks difficult because they are not just insects, but spider-like, then insecticides will not work. To get rid of the tick need to use acaricides or insectoacaricides. The first thing you need to wash the plant with water to reduce the number of mites. Then treat with acaricides (Sunmite, Apollo, Actellik, Fufanon, Nissoran, Oberon, Actofit, Fitoverm) 3 or 4 treatments with a five-day interval. Mite is a very insidious "animal" capable of adapting and therefore for the successful extermination of the population should use different chemicals to avoid addiction from ticks.
Thrips is a gray or translucent insect, has an elongated body and wings. Thrips appear as a result of high temperatures. and when the air in the apartment becomes dry. Since thrips has wings, it can move around the apartment and thus harm all your plants.
With the defeat of this pest, the color of the leaves changes to a lighter color and “depressed” points and strokes appear on the back side of the leaf, sometimes they can be silver. Thrips drinks cell sap, which leads to the death of the flower. To reduce the thrips colony, the plants should be washed under a warm shower, then treated with insecticides (Aktara, Aktellik, Aktofit) three times with a break of 5-10 days, depending on the selected drug.
Mealybugs - white bugs on an orchid, leaving a white bloom similar to cotton wool. Appears as a result of improper care. It can be found between the leaves. and beneath them, he hides in hard to reach places. A cotton pad or a toothpick will help get rid of all visible individuals. Then you need to wash the plant. After that, it is necessary to treat the plant with insecticide, Aktara will cope best of all, it can be watered and sprayed. Spraying should be carried out 3 with a break of 7 days. After watering, the protective effect lasts for a month.
The shield is a pest which is quite easy to find in the adult stage since they are covered with brown “shell” and look like tiny growths from the inside of the leaf most often. At the larval or “teenager” stage, the shield cannot be seen with the naked eye. In order to get rid of the scale you need to manually remove all adults, rinse the plant under the shower, to reduce the number of "adolescents" and larvae shchitovki, then spray insecticides. Treatments to spend 3 with an interval of 4-8 days, depending on the selected drug.
Aphid rarely appears on orchids, but nevertheless, such cases are not excluded and you need to know how to get rid of it. Due to the dry air in the apartment or when the plant is rarely watered and often overdried, aphid may appear. These are insects of green or blackish color, you can notice them with the naked eye. Often aphid leaves on the leaves sticky drops. But if you find sticky droplets on the leaves, but you have not identified any pests, do not rush to treat the plant with chemicals, this may be the “nectar” that the orchid produces when it is watered excessively, rather than aphids.
If you still have aphid on the orchid how to get rid of it? First you should wash the flower under water, you can wipe it with soapy water (household soap or “green soap” is used for plants), then treat it with insecticide (Actofit, Fitoverm, Aktara). 2–3 treatments should be performed with an interval of 5–8 days.
The least dangerous, but no more pleasant pest is the poduras. Pods in orchids are small white or gray bugs that inhabit the substrate or on its surface. Podols appear due to over-wetting of the substrate and feed on rotting roots, the upper part of the plants rarely falls under their “menu”, but nevertheless in places damaged by pouters, rot and bacteria may develop, especially during a favorable period (cold, lack of light, excessive watering).
Fighting them is not particularly difficult: you need to dry the substrate well in a pot with an orchid, and then shed it with an insecticide (Aktara, fitoverm). It will be enough and one treatment, but it is better to hold them two. It is necessary to adjust the watering in order not to flood the plant and not to provoke the appearance of suckers.
What you need to remember when processing plants from pests
- it is necessary to process not only the diseased plant, but also the plants standing with it on the same window sill,
- before treatment you need to wash the plants with water or soapy water, you can use a shower to reduce the number of pests,
- during processing, do not neglect personal protective equipment (mask, gloves), work in a well-ventilated area, away from pets and children,
- if it is possible to treat the plants outside the house, then do it in the morning or in the evening, when there is no wind and dry weather,
- when breeding chemicals strictly follow the dosage, so as not to "burn" the plants and the interval between treatments is also important to observe,
- Always treat the plants at least three times and for about a month closely observe if the pests reappear.
So as not to have to treat orchidsbetter to prevent possible problems. What to do to avoid the appearance of pests:
- always inspect the newly purchased specimens for the presence of a pest armed with a magnifying glass,
- regularly inspect your entire collection of plants for the presence of a pest,
- Newly purchased orchids should be put in a “quarantine” for a month, i.e., apart from other flowers, and see if uninvited “guests” appeared on them,
- if you were given a bouquet, you should not put it next to house plants because there is a high risk of catching the pest,
- optimize orchid growing conditions:
- increase the humidity (this can be done with a humidifier or put an orchid on wet expanded clay / pebbles, just so that the pot does not touch the water),
- adjusting watering (do not pour or over dry the orchids) it is better to water less than pour, on average it is necessary to water the orchids once every 10 days by soaking the pot for 5–10 minutes, if the roots are silver, the pot is light and there are no drops in the pot can,
- to monitor the temperature in the room (in the hot season on the southern windows you need to tint the plants),
- provide good lighting (in the fall and winter, light up the orchids with fluorescent lamps or phytolamps, especially if they “live” on the north window),
- Sometimes it is worth pampering your plants with vitamins and means that support plant immunity (Zircon, HB -101).
If you want toso that the orchids will delight you with flowers, and you will not have to fight with endless crowds of pests, you should take a little care and attention to your beauties, because healthy plants are invulnerable!
Causes of pests
Orchid is a very capricious plant. To ensure her healthy growth and lush flowering, the organization requires careful care. In addition to diseases, orchid phalaenopsis is susceptible to the attack of pest bugs.
Insects can get to the indoor flower in the following way:
- The flower was purchased already infected by insects. In the flower shop, before you buy a plant, you need to conduct a thorough inspection. The site of pests are the sinuses, as well as the underside of the leaves.
- The orchid was transplanted into a pest contaminated soil. If you take raw land (from a flower bed, in forests or in parks), then the risk of soil damage by various pests is very high. For indoor flowers it is recommended to purchase a special primer (you can buy in a specialty store).
- Pests "moved" to the orchid from the neighboring indoor plants. If indoor plants are attacked by insect pests, then almost 100% of all new flowers will also soon be affected. To get rid of parasitic bugs, it is required to take appropriate measures when the first signs of their vital activity appear.
Beautiful orchid attracts pests. Aphids, mites, and spiders can encroach on leaves and fragrant flowers.
It is very simple to detect the vital activity of pests on a plant - its leaves begin to curl and turn yellow, the “consequences” of wrecking bugs (yellow or black spots, through holes, etc.) are clearly visible on the surface, the flowers fall.
Some insects are carriers of serious diseases. To prevent disease and death of the flower, it is necessary to timely deal with pests.
What pests often affect orchids and how to get rid of them?
- small insect, the length of its body is 2, 5 mm.,
- Externally, thrips resemble oblong “sticks” of black or dark brown tone,
- thrips can move quickly,
- insects hiding in the ground, and at night "attack" on the flower.
Signs of flower damage:
- on the surface of the leaves of the plant, you can visually see small black dots, as well as the thinnest silvery film,
- if at night to turn on the flashlight and direct it to the orchid, then there will be a mass of small insects hurrying to hide from the bright light in the soil.
Danger to the flower:
- Thrips lay eggs inside the leaf. The hatched larvae begin to actively eat the leaf pulp, with the result that dark spots appear on its surface with time. An insect-infected leaf curls and falls.
- Thrips can parasitize not only on orchid leaves, but also on its root system, as well as flowers. Wrecking thrips causes the death of the plant.
- Gently wipe the affected plant leaves with a damp cloth.
- Treat the flower with special compositions (Fitoverm, Aktar).
- As a preventive measure, wipe the leaves of the plant every week with a damp cloth.
- a small insect, but very dangerous for indoor plants,
- the pest body is elongated, ribbed, its surface is covered with white bloom.
Signs of flower damage:
- the mealy worm forms deposits (externally similar to a web or a small piece of cotton wool) on the surface of the affected part of the flower,
- the leaves of the affected plant are twisted, the structure of the stem and flowers are deformed,
- A numerous mealyworm damage often provokes plant rotting, and signs of a bacterial fungus form on it.
Danger to the plant:
- White bugs parasitize under the stem scales, under the base of the flower, on the root system of the plant. The pest hides in fallen leaves on the top layer of soil. Affected parts of the plant dry, fall off.
- Late treatment of the plant leads to its death.
- To collect from the top layer of soil the fallen leaves, dry inflorescences.
- Treat the lower part of the flower and the soil with a special compound (Fitoverm).
- Inspect the flower daily: clean and destroy adult pests, collect its larvae. Wash affected orchid structures with a damp cloth.
- Prevention: Do not allow the pot to have fallen leaves and dry parts of the flower. Periodically wash the leaves and stem of the orchid with a damp cloth or clean warm water.
An orchid can parasitize several species of mites. The problem of pest detection is that they are too small; it is not possible to visually examine them on the flower.
Ticks that parasitize houseplant:
- False spider mite. The insect is colored yellowish or red, its larvae have the same coloring. Food pest - sap plants. Signs of detection: the lower part of the affected leaves is covered with white shiny bloom, over time, brown spots appear at this place, and the affected leaf will fall off. In addition to the leaves, the false mite also affects the flowers. The affected inflorescence falls, even without blossoming.
- Bulb mite. The insect is small, it is very difficult to notice it visually. The little body of the pest is white in color, its larvae are yellow and white. The bulbous mite feeds on the juice of the roots of the orchid, gradually the insect's wrecking leads to the death of the flower. Another place of onion mite localization is the flower stalk near the base of the leaves. Defeat of an orchid with an onion mite can provoke the development of a fungal infection.
- Red spider mite. Small insect whose body is painted in red tone. Signs of a damaged flower: the surface of the affected leaves is covered with white cobweb. On the bottom of the leaves are formed yellow spots. Red ticks feeding on sap plants gradually lead to the death of the flower.
- spray the affected plant with a special compound (Fitoverm),
- move the plant to a warm room with high humidity,
- put a pot of water near the orchid (mites do not like moisture, preferring dry areas).
- remove and destroy the pest-affected part of the root system,
- process the soil with a special compound (Fitoverm),
- spray the plant with a solution against pests.
Red spider mite:
- increase the humidity in the room (near the flower to place a pot or pan with water),
- process the affected flower Fitoverm.
- small pest, body length is 2 mm.,
- Externally, the body of the shield is similar to half a match head,
- the insect is firmly attached to the leaves and parasitize them for a long time,
- females of the pest secrete substances on the surface of the affected part of the plant that trigger the development of the soot fungus.
Signs of flower damage:
- the surface of the affected plant structure becomes denser, acquires a brown color.
- wash the plant regularly with a damp cloth
- remove pest accumulations from the surface of the flower,
- process the orchid with a special compound (Fitoverm, Aktellik),
- in case of heavy lesion with a shield, it is recommended to transplant the orchid into a new pot and completely replace the soil,
- prevention - regularly inspect the plant, conduct water procedures.
To keep the orchid luxurious and charming, it needs to provide quality care. With insufficient attention, the plant begins to dry and die.
If a flower is damaged by pests, it is necessary to urgently take appropriate measures. Fighting them must be effective and safe for the plant. Otherwise it will lead to the death of the orchid.
The whitefly is a small white butterfly laying its eggs on the underside of the leaf or under the bark. Butterfly larvae eat the leaves, causing damage to the plant. Spraying a plant is a waste of time: butterflies quickly flutter and it does not harm them. To get rid of them, move the leaves and slap the fluttered insects.Methods of dealing with the remaining larvae: treat the soil with a solution of "Phyto farm" or "Aktelikt", repeat the treatment after a week. It is necessary to wash the foliage with running water for at least five days. Folk method of dealing with pest orchids - make a soap solution and wipe the entire ground part of the plant.
Earthworms often crawl into pots standing on the ground in stores or greenhouses. They do not harm the plant, but they make gardeners nervous. To get rid of worms, put the pot in a deep container filled with water, so that the water covers the soil in the pot. After 7 - 10 minutes, the worms will crawl out. Repeat the bath after ten days.
Dummy and shield
Dummy shield and shield are frequent pest phalaenopsis. About the presence of these parasites prompt yellow or brown growths, under them sits an adult individual. Insect larvae move throughout the plant, drinking juice and hindering orchid development. To get rid of the parasite, prepare a solution "Aktellika", as indicated in the instructions, and process the plant. Re-treatment is carried out in a week. The plant needs to be transplanted into a new ground, as a preventive measure, flush both the plant and the ground with running water. Есть и народные средства борьбы с этими вредителями орхидей. Метод, подходящий растениям с плотными листьями, – протирание этиловым спиртом. Толчёным чесноком можно протереть повреждённые места цветка и наросты, под которыми прячутся взрослые особи. The third method is a solution of olive oil with water (2 tbsp. Liters per liter of water). It should be applied to all above-ground parts of the plant with a brush for drawing.
Ticks (spider mite and flat mite)
Flat-tick mite is a microscopic insect of red or yellow color with green larvae. You can see the insect with a magnifying glass. A parasitic flower loses white-coated leaves. If time is not detected, the peduncle buds will begin to fall off, not having time to blossom. Spraying with "Fitofarm" will help to get rid of the insect. At a room temperature of not more than 20 ° The procedure with ° 0 should be repeated three times, once a week. If the temperature in the room is above 30 ° C - three to four times with an interval of three days. At the same time, rinse the plant and the soil with running water for five days.
A spider mite on an orchid can live a long time, as it has the ability to develop immunity against insecticides. Therefore, getting rid of the insect, alternate preparations. Actellic, Tiofos, Fitoferm and Neoron are suitable for fighting pest.
Popular method:Cyclamen tubers cut into large pieces and boil in water for forty minutes. Broth insist day, then filter and spray the plant with them. Spraying is carried out three to four times every five days. For orchids with dense leaves, wipe with medical alcohol will do. There is one subtlety: before you wipe, test the reaction of the plant in one place.
As already mentioned, the orchid often suffers from pests in the soil and it is necessary to know how to get rid of them without the risk of losing the plant or re-invasion of the parasites. These pests include wood lice. This insect eats away everything that comes its way: leaves, branches, young shoots. You can learn about their appearance by noticing the holes on the plant. Water procedures will help you - put a pot with a flower in a deep basin filled with water. Water should cover the potted soil. Parasites themselves crawl out of the ground. Repeat bathing after a week. In the case of a large number of parasites and failure in water procedures, change the soil. The plant must wash the roots.
Popular method:To lure woodlice out of the ground, around the pot place the bait from pieces of raw potatoes or apples.
Rootbird - this parasite on the orchid harms the root system of the flower. The insect has a body in size from two to four centimeters, yellowish, gray or pale pink. As a result of his life, the plant fades and dies.
The infected orchid is removed from the pot, the roots are thoroughly washed and watered with a weak solution of potassium permanganate. When the root system dries, the plant is transplanted into a new soil, pre-disinfecting the pot. Old substrate must be thrown away. Another method is to tillage the soil with a dry powder insecticide. When you water an orchid, the insecticide reacts with water, saturating the roots with a chemical. The barn, eating poisoned juice, dies.
The pods are gray or brown small insects that live in the soil and feed on the substances there. Buttocks are the most innocuous of the pests of orchids, but they also need to be plagued and treated. In a small amount, bugs feed on what they find in the soil, and after breeding, if there is a shortage of nutrients in the soil, they can switch to young root shoots.
With the appearance of blackflies, treat with the preparation "Fitoferm", referring to the instructions. Repeat the procedure after a week. For prevention, treat the place where the pot is kept with bactericidal compounds and do not allow overflows.
Nematodes are small worms up to two millimeters, it is difficult to examine them immediately. With a long stay of the parasite on the orchid, the plant receives poisoning from waste products of the pest. Gradually, the orchid becomes covered with putrid touch and dies.
Infected plants must be removed from other flowers. For treatment, dilute the tablet in a liter of water with a left-leveled tablet and pour soil over it. Repeat watering in a week. Another method - water treatments in water with a temperature of 40 degrees. Nematodes die at these rates.
Aphid on the orchid - carrier of diseases. You can easily notice it and get rid of it immediately.
The insect, feeding on the sap of leaves, leaves behind itself a deformed tissue covered with a sticky substance. On this sticky mass, spores of a black fungus multiply with time. Treatment consists of spraying insecticides.
You can cope with aphids with the help of popular methods. Prepare the onion brew: the ground onion is filled with boiling water and infused for seven hours. Then the infusion should be drained and sprayed the plant. Perform the procedure several times a day for four days. The second method: wash the plant with a tobacco-soap solution. You can also use the infusion of the peels of any citrus. Pour the peels (100 g) with a liter of water and leave for three days. Spray the orchid every five hours with the mixture. Dry crusts can be put on the ground around the stem of the flower.
Thrips are invisible because of their small size - just over 2 mm. The parasite destroys not only the foliage, but also the roots of the orchid. Thrips lay their offspring in orchid leaves, hatched larvae from eggs, feed on the juice of the latter. Black spots appear on flowers, the foliage dries, and growths form on the roots. If time does not get rid of the pest, the plant will die.
To get rid of thrips, you need to spray the flower "Aktellik" or "Fitoverm" three times. The interval between spraying ten days. If you do not want to use chemicals, spray onion extract, or a solution of olive oil and water.
What are the dangers?
Since the pests feed on the juice and nutrients in the orchid, it stops growing, flowering stops or becomes scarce, the leaves change shape, become elongated. After a while, the phalaenopsis will start to wither and then die. What parts of a plant strike? Pests mainly affect the stems, roots and leaves of the plant.they suck the juice out of these elements, causing the flower to wither and die.
How to find out about their existence?
Most often, parasites attack a flower in the summer. There are several ways to detect them:
- At night, put a slice of an apple or cucumber around the plant right in the pot. In the morning you can see who came to eat.
- This method allows you to identify insects that live in the root system. It is necessary to immerse the pot with a flower in a container with water. Parasites within 1-2 minutes will quickly float.
To get rid of pests that hit phalaenopsis, you can, if you use the following drugs:
- Aktara. This drug has a systemic effect on pests such as scab, chervintsy, aphid and thrips. At the same time the tool is absolutely safe for others. When using it, the plant receives protection for up to 2 weeks.
- Aktara. It is possible to use means for spraying or watering. Processing carried out with an interval of 7-10 days.
- Actellic. This drug is effective against aphids, whitefly, mites, fleas, scutes, and thrips. Sometimes even one treatment is enough.
- Agrevertin. This remedy acts against the same pests as the previous drug, but only it has a weaker effect. To prepare the solution, take 1 liter of water and 5 ml of the product.
- Bi 58. This is a powerful drug of universal application. Disposable treatment is carried out with a solution obtained from 30 ml of product and 1 liter of water.
You can get rid of pests with the help of proven home remedies:
- Phalaenopsis leaves can be treated with a cotton swab dipped in vegetable oil. Under the oil film, cherventsy and shchitovki will start to choke. To carry out processing in the morning or in the evening.
- To carry out oil spraying should take 1 liter of water and 40 ml of olive oil. The resulting emulsion is applied to the affected areas. To do the procedure 1 time per week 3 times.
For the treatment of phalaenopsis such biological preparations are effective:
- Bicol. This is an acaricidal drug that is derived from the bacterial strain Bacillusthuringiesisvar thuringiesis. Apply to eliminate spider mites. Bicol quickly eliminates pests, as it has an intestinal effect.
- Verticillin. This is an insecticide that was derived from the fungus Verticilliumlecanii. The drug is used in the fight against whitefly. Its effect lies in the fact that the conidia or blastospores of the fungus seep through the integument of the insect and penetrate into its body. There they grow and infect his organs.
Common harmful insects with photo
These pests can infect the plant in the store or at home. Ticks pierce phalaenopsis leaves, causing them to hurt., dry out and fall away. Buds can not open, and instead of this slow die. The parasite can be recognized by the presence of a cobweb on the leaf plate. You can get rid of ticks if you collect them with your hands and put them in water. You can also spray the plant with Fitoverm once every 2 weeks.
These little pests live practically everywhere in the gardens. They have a black color and 2 pairs of wings, so moving from one plant to another is not a problem for them. They hide in the ground, so it is much more difficult to find them. After the bugs on the foliage silver traces remain. Thrips suck the juice from phalaenopsis, and in the roots they lay the larvae. To overcome the pest, you need to spray the flower with the complex solution Aktellika and Fitoverma.
This group includes pests that feed on plant sap. Most often it is springtails. You can notice them on the brown color. They do not crawl and do not fly, but jump, so it is very difficult to catch the parasite. If there is a massive pest damage, they feed on the roots of the orchid. You can get rid of springtails, if you reduce watering (2 times a week), and still process the flower with a phyto-farm.
This parasite does not pose a danger to the flower, but its release, which it leaves on the leaves, prevents them from obtaining oxygen. It is on such leaves that bacteria and fungi begin to multiply. To get rid of aphids, you need to use a solution with soap, but they do not spray the orchid, and wipe the affected leaf plates.
These are worms that are rounded. They seep into the roots, stem and leaves. Pests feed on all the beneficial substances of phalaenopsis and suck the juice. Nematodes not only feed on the plant, but also leave their secretions on it. Because of this, the orchid stops growing, and dies out after a while. Nematodes do not like hot water, so you can warm the flower. Just do it carefully so as not to destroy it.
These parasites are frequent guests of the orchid. You must fight them immediately, immediately after detection. And though wood lice move slowly, they are quite active in the ground. They hide during watering, so finding pests is not easy. To overcome the pests, you need to lower the orchid into the water and wait a bit. After 2-3 minutes, wood lice begin to crawl out. If the parasites remain, it is better to transplant the flower, just before that, thoroughly rinse the roots.
Shchitovka and false shield
These insects suck out all the nutrients from phalaenopsis, and after them sticky liquid remains on the leaves and stems. It is an excellent medium for the development of fungus and rot. Adult shchitovki can lay larvae directly on the stem. They are attached to the plant, feeding on its juices. In a few days, the individual will become mature and will cause significant damage to the plant.
To defeat such parasites is quite simple: you need to wash the flower with water, after which the insects will go away. You can also process the orchid Aktellik and Fitoverma. To carry out such a procedure 2 times a month. After completely getting rid of parasites, phalaenopsis needs to be transplanted.
Buying an infected plant from a store
Look carefully at the orchid. and substrate in the store.
Consider the outletto see pests: scutes, thrips, centipedes.
If you notice spots and dots on the leaves, this is a sign the presence of parasites.
The middle of the plant should be clean, without spots and rotting.
If you find that the pier sticks out from the outletone sheet that means growing point is healthy.
Carefully inspect the roots. If they are gray or green, then that's good.
If there are air roots above the soil, this absolutely normal.
Healthy roots are firm and elastic if touched.
Do not acquire a culture with brownish, dusky or rotten roots.
Shake the pot, a healthy plant will not hang out.
Better buy a plant that contains flowers and buds.
On flowers there should be no spots or dotsthey must be fresh and supple.
Transfer from another plant
Pests can crawl on phalaenopsis from neighboring flowers.
If you have a lot of plants in the room, the risk of occurrence of harmful insects increases.
Many ticks, bugs drink juice from a variety of plants and crawl in search of a new plant.
Do not put plants too tight on the windowsill.
These are very small parasites, their body is 2-2.5 mm, they resemble "sticks"having brownish or black wings.
Insects move fast, they penetrate the soil.
It can be understood that the plants were attacked by thrips, if you saw white specks and dots on leavesand a thin silver film.
Thrips are small insects with an elongated body.
If you get up at night, turn on the flashlight and light up the ground, then you will see thrips, which are on the surface of the substrate.
They lay eggs inside the leaf, then because of them the larvae hatch, which eat the leaves. On the leaves there are spots, they turn brown, fall.
On the flowers black dots are visible, and on the rhizome - “waist”.
It's tiny worms up to 2 mm longthey feed on juice.
On the roots of a damaged orchid necrotic spots appear, then the disease flows into the leaves and pseudobulb.
Foliage turns yellow and falls. Then the pseudobulb dries out.
Phalaenopsis can be attacked by the short-haired nematode Scribner, during her activity roots die off, and the plant dies.
Tiny insect with body 0.7–0.9 mm long, the body is dark brown or black.
Females set aside brownish eggs. They run very fast. From the light run away and hide.
Can crawl all over the orchid, but eggs lay on rotten roots, on the fallen leaves.
Appear in the wet ground. They eat fallen leaves and do not pose a danger to orchids.
Signs and description of a tick:
- He has a little body in the form wide oval, by the end of the betrothed,
- Body color is white or cream,
- Insect up to 1.5 mm, has 2 pairs of legs.
Tiny parasite penetrates the roots, eats juice.
If you later discover a tick, then roots become in the form of threadshaving a void inside.
Slugs in the substrate
Slugs and snails eat everything:
If you find them, then catch everybodytransplant orchid. It is better to reduce the amount of watering.
Put a piece of cucumber or apple in the form of a bait on the soil and see if anyone crawls out to eat a piece. To prevent mold on the soil, clean a piece in the morning.
You can put a saucer, pouring dark beer into it. Stand up and try it at night. collect slugs by hand. Usually, new snails from eggs appear in a week, therefore constantly put baits.
Podura in the substrate
Pins resemble tiny caterpillars:
Pododa appears on the soil surface in early spring, feeds on various plant debris.
Have them body 2 mm long, but there may be larger specimens up to 1 cm long.
From the bottom of the abdomen they have a fork, with its help crawling and jumping.
Ghosts appear if you are too fill phalaenopsis.
Moisture stagnates on the surface of the substrate and silt appears.
To catch the fossil - a phalaenopsis pot, place it in a basin of water so that the water completely covers the pot.
Then the poduras will pop up, and you can collect them.
Mokritsa has an elongated bodycovered with scaly armor.
The body is dark gray or yellowish marble. She has 7 pairs of legs and antennae.
In length adult up to 1 cm. Usually lice crawl into the substrate after the removal of orchids on the street.
Young sprouts, leaves, stalks, roots eat the moss, holes appear on them.
Mokritsy afraid of water, because of this, lower the phalaenopsis container for 10 minutes. completely into the water.
And then wash away the insects soapy water.
If there is a lot of lice, change the substrate, transplant the flower, after washing the roots.
If your phalaenopsis is on a loggia, then adults butterflies can lay eggs on it, and the caterpillars, as soon as they hatch, immediately begin to eat the green parts.
It is possible to eliminate pests spray the plants with decoction with onions, garlic, hot pepper, jalapeno, basil, coriander, wormwood, mint.
Put the leaves in hot water. Strain before use.
If there are too many caterpillars, then take the acephate and spray Phalaenopsis, but remember that the composition is toxic, therefore, comply with safety measures.
Means of struggle
Drug destroys aphid, whitefly, thrips, scythe, false shield, soil flies.
In Aktar is thiamethoxam, he completely eliminates pests.
Thiamethoxam completely decomposed in soil, растворяется в воде, поглощается фаленопсисом из земли.
Актара воздействует на пищеварение паразитов, они сразу же прекращают питаться орхидеей.
Pour 4 g of the drug in 5 liters of water, and then use.
You can put a pot with a flower in this solution for a few minutes, or you can spray the leaves and pour the substrate with the solution.
Aktar can be easy mix:
Actellic considered analogue of the drug Bi-58which is forbidden to use in Russia.

- Do not neglect preventive measures,
- Properly care for phalaenopsis,
- Remember that among all means of extermination of pests, fitoverm is considered the safest biological product.
The orchid is one of my favorite flowers at home, given as a birthday present. Recently I read about preparations for spraying street plants, but I wondered if they were suitable for orchids. to protect against diseases. In particular, I mean fungicides.
Fungicides are able to fight fungal infections and other diseases of orchids. Organic fungicides not only fight against fungi, but also contribute to the development and growth of the plant. The methods of application are different: they can be processed during transplantation, sprayed a diseased plant, or used during watering. For orchids, fungicides can and should be used.
Fungicides are suitable for absolutely all outdoor plants - without exception. If you annually process them an orchid, protect it from diseases.
Two and a half years ago I bought a pink orchid phalaenopsis yellow orchid. A couple of weeks ago, it bloomed again, but a pink border appeared at the edges. The flower has become even more beautiful, but this is the first copy of my thirty, which changed color. Is this normal?
And today I discovered some tiny moving black dots on the roots and the bottom yellowed leaf of a flower that barely went out. In August, the leaves from the neck began to quickly turn yellow, I cut them all, because before that I completely rotted the flower in quarantine, and I watered healthy roots every week, from January the radical root grew, it already has five leaves, and suddenly some kind of creeps creeps on it and 2 yellow leaves fall off. What to do?
Reduce watering, do not over-humidify. Wash the plant with a solution of laundry soap and water, and spray Fitoverm. Color change happens, do not pay attention to it.
Most likely you overdid it with watering, which phalaenopsis do not like. Watering an orchid is necessary only when the roots are dry and the substrate is dried. I advise you to wash the leaves of the plant with a solution of household soap, and then with Phyto farm process.
Hello, please help . I found very small bugs with the size of a small dot on my orchid. They are black and almost imperceptible, the leaves began to turn yellow and red at the base, and eventually to anger. Small drops of sticky Russia were also noticeable. Please help, as they have spread to two orchids (
Good day! Treat the plant with Tanrek's solution, its advantage is that it does not accumulate on the plant itself, as soon as it destroys the beetles, it evaporates from the leaf surface.
Good afternoon, thank you very much for the advice.
Victoria, first of all isolate the infected plants from the rest of your collection, then change the soil to a new orchid, rinse the roots well, and treat the plant itself with “Fetoparm”. Further for several days I advise you to rinse the orchid under warm running water.
Good afternoon, thank you very much for the advice.
I can not find information - which of the pests eats the unblown buds of phalinopsis?
Good day! I convey the answer from the author of our articles:
Unfortunately, there is no photo so that the pest can be identified by the nature of the damage. Therefore, to choose from, unblown Phalaenopsis buds can eat:
• Little Fingers, the main damage is caused by their larvae and caterpillars. The orchid must be transplanted into a fresh substrate, thoroughly washing the roots and leaves. Peduncle will have to be removed. If you are transplanting into an old pot, then it must be disinfected. Drugs that help exterminate a pest should be based on substances such as Thiacloprid, Azadirachtin or Spinosad.
• If the peduncle of your orchid is practically lying on the leaves, and not worth it, then it can be a shell mite. To get rid of this pest, transplantation into a fresh substrate and treatment with acaricides several times with different active substances will also be required.
• Aphid. The same orchid will require transplantation and thorough washing of the whole plant. Insecticide treatment marked "aphid".
• It can be thrips. Treatment - as in previous cases, only chemicals should affect this pest.
Hello! Your help is very necessary. I have an orchid, a gift, I can’t say the age, it has 7 leaves. Recently I noticed a mealybug on it, turned to the Internet and processed it as it is written. Now everything seems to be clean. When processing, I pulled it out of the ground to wash and treat the roots, and I saw that some of the roots had rotted. I cut them, processed the sections with activated charcoal. In general, the roots are left quite a bit in the ground, but a lot is growing above the ground, what is visible. Prokalila its soil-bark in the oven, and planted it again. But a day later I noticed that she began to lose the turgor of the leaves, and not only the large lower ones, but also the one that only grows from the middle. This orchid, released about 2 flower stalks about a month ago. Please tell me what to do, it's a pity to lose the plant, can I trim one peduncle and it will be easier for the plant to recover? Every day I wipe the leaves 2-3 times with a solution of succinic acid. All this happened 3 days ago. I am waiting for your advice. Thank you.
Hello! I convey the answer from the author of our articles:
It is a pity that you did not send a photo of your plant. After the mealybug, the orchid could be infected with Fusarium. If after the destruction of the pest was not carried out processing fungicides - process, in the instructions should be marked from Fusarium. If, during the re-planting of an orchid, aerial roots remained in addition to the pot, then the remaining roots may not be enough to provide the orchid with moisture.
Try the following:
1. Remove the plant from the pot.
2. Soak the roots, including the air, for 20-30 minutes in a solution of Gamair and Alirin, sold in stores for summer residents. You can soak the entire orchid completely, just do not forget to carefully wipe the leaf axils.
3. Inspect the base of the stem. If it is black and the base of the roots is dried, then cut a few millimeters from the base of the stem. In the case of a brown or burgundy cut, cut further down to green. If after 15 minutes the cut remains clean, then coat it with undiluted “Maxim”.
4. Dry and plant in a fresh substrate with aerial roots. After soaking, they will be more elastic, and it will be easy to do.
Slugs and snails
Slugs and snails are especially dangerous for plants, as they eat up all the juicy parts of an orchid. These parasites love heat and moisture, and often you bring them along with the store you buy in the store. In the case of snails and slugs need careful cleaning. For pests put bait: slices of apple or cucumber. When the invertebrate creeps out, it is harvested by hand. The collection procedure must be repeated until complete disappearance. Snails can leave offspring that appear after three weeks, so make a control bait.
So, you bought an orchid. Do not rush to transplant it and put on a permanent place. Make her a water bath: put the pot in a container filled with water so that the soil in the pot is under water. You will see whether the pests have been brought with you or not. If brought, immediately treat the flower, let it dry and plant in a properly selected soil. For orchids, phalaenopsis is a soil containing bark and moss. In such a ground, the orchid will feel as if it were in natural conditions, because in nature the flower grows on tree trunks or peeled stumps.
What it is?
When choosing an orchid in a store, the florist often inspects only its leaves, flowers and the stem. However, it is very important to carefully check the soil in the pot as well. It is in the substrate that pests dangerous to the flower prefer to settle. These are all sorts of beetles with antennae, white worms, winged insects, etc.
The most common pests include:
The negative consequences of the life of parasitic insects on an orchid can be very different - from growth inhibition to its complete destruction. If the leaves began to turn yellow, dry and curl, or their surface is covered with a sticky mass, if there are strange bumps on the stem, points and punctures that were not previously observed, then there is a huge probability that the flower was attacked by pests.
Determination of insect species
Determine which pest will have to fight either by the appearance of the insect, if it was found in the process of inspection or immersion of a flower pot in water, or by the harm that was caused to the plant.
- Brownish-yellow tubercles on the stem talk about infection with a shield.
- The deformation and twisting of the leaves implies that nematodes or aphids may be present in the flower pot.
- A large number of black dots on the plant directly indicates that the orchid is threatened by thrips.
- And if you find a bloom on the orchid, which is very similar to a web, then the plant has been subjected to the most malicious pest - a spider mite.
Common ways to fight
Perhaps, it will turn out to be limited to mechanical removal of harmful insects. A careful inspection of the plant, the collection of the found pests, cutting of yellow leaves and sluggish shoots, carrying out the procedure of immersing a flower pot in the water, of course, will have a positive effect. But in this way 100% deliverance from parasites is not achieved.
Far more pronounced effect will give all kinds of drugs, both chemical and folk. With their help, you can fight not only with the insects themselves, but also with their larvae, which will provide a more complete treatment of orchids.
- Soap solution. In 1 liter of water dissolve 1 tablespoon of any liquid soap. Suitable even dishwashing detergent. As an option, you can take the laundry soap, rubbing it pre-grated. This solution should thoroughly wash the entire ground part of the flower.
- The infusion of tobacco. 30-40 gr. Tobacco dust pour 1 liter of water. Allow the mixture to infuse for a day, periodically stirring the ingredients. After one day, strain the infusion and spray the plant with it.
- Onion infusion. Take the average onion, mash it in a mush and pour boiling water. After 7 hours, the infusion will be ready for use. Such a mixture is treated with leaves and a flower stalk for 3-4 days in a row.
The name of the parasite, the appearance and photo, than to process the flower
The midges are able to multiply very quickly, so the fight against them must begin as soon as possible. But first you need to find out their appearance. Most often they are sciarides, they are also called “mushroom mosquitoes”. It is easy to recognize them - a black body, a length of about 4 mm, a pair of almost transparent wings. The insect itself is not dangerous for the orchid. But his the larvae adversely affect the roots of the plant, gradually weakening the flower.
To combat the midges, complex treatment is resorted to - the upper part of the plant is sprayed with Reid or Raptor preparations, and the substrate is pickled with Fitoverm or Actellic.
Supporters of popular methods use tobacco, a solution of household soap or potassium permanganate, citrus peels or garlic cloves, etc.
The appearance of an ant is familiar to everyone - red or black insects, from 2 to 4 mm long, have 3 pairs of paws. They live in numerous colonies. They love to feast on the sweetish discharge of aphids and cherries. Swarm tunnels in the ground, ants damage the roots of the plant, as a result, his death may occur.
Ants are able to multiply rapidly, so it is impossible to delay with their extermination. If you are a supporter of radical methods, then you should immediately use chemical means. For example, "Fitoverm", "Permethrin" or special traps with insecticide, used according to the instructions, will give a quick and lasting effect.
Experienced flower growers offer these pests to try to just drown. To do this, the flower pot is poured with plenty of water (it is convenient to do this by placing flowers in the bath), after which it remains only to wait 30 minutes. During this time, some of the ants will scatter, and the remaining insects will drown. After the procedure, it is desirable to change the soil in the flower to a new one.
Another common remedy in the fight against ants is a soap solution.wiped with orchid leaves and stalk.
In general, domestic cockroaches do not live in flower soil. However, they can easily arrange a temporary shelter in the lower part of the flowerpot. Cockroaches usually enter the pot through drainage holes. Plants that are on the ground are especially susceptible to this.
It is easy to cope with them - cockroaches do not tolerate abundant watering, as a result of which they run away or drown.
Nematodes are light translucent worms about 2 mm long. It is very easy to identify this pest, it leaves characteristic grooves around which bright spots are visible. After some time, these spots darken. Nematode affects both the stem with leaves and the root system.
To deal with it is quite difficult.Usually flower growers, instead of getting rid of insects, prefer to throw away the diseased plant so as not to infect other flowers. But at least try to reanimate the orchid and shed the soil with Decaris solution in a dosage of 1 tablet per 1 liter of water.
What actions for destruction can not be taken?
When dealing with phalaenopsis parasites, the following actions should not be performed:
- Use strong pesticides, as they can destroy not only pests, but also beneficial organisms.
- Use solutions prepared over several days. To eliminate insects suitable only freshly prepared composition.
- To prepare the solution is not according to the instructions, without complying with the concentration, norms of costs and technology.
Care of flowers after their treatment
After all pests of phalaenopsis have been eliminated, the flower must be properly maintained:
- Lighting. Orchid must be placed on a site with good lighting, but without penetration of direct sunlight. Due to lack of light, the leaves are drawn out, and flowering becomes rare.
One of the rules of phalaenopsis care is pest prevention. But due to bad weather conditions or a violation of agricultural practices, the invasion of parasites cannot be avoided. So that the orchid does not wither and disappear, it is necessary to start pest control and plant treatment as quickly as possible, using the most safe means possible.
- Like the woodlice, the millipedes fall into pots that are on the streets in the summer.
- And since they do not have an extensive menu, they begin to eat up tender and juicy roots and newly growing orchid leaves.
The very first and most important step, in order to prevent the appearance of parasites on orchids, will be the placement of newly acquired flower pots in quarantine.
The duration of quarantine should be at least two weeks, during which the flower should be carefully monitored and, if necessary, preventive processing. Only this way it will be possible to secure those already “living” in the apartment.
The whitefly is a small white butterfly. It lays the larvae on the underside of the leaf, as well as under the bark of the plant. It is the larvae that do the most harm to the orchid, they are quite damaging to the leaves of the flower.
To eliminate the whitefly, the insects themselves are manually caught and killed. The larvae are neutralized with a chemical preparation, for example, "Fitoverm" or "Aktellik".
Aphids can be seen with the naked eye - these are small bugs of black or greenish color. This pest loves mostly young shoots or leaves and usually parasitizes on them, leaving a sticky patina in which the fungus multiplies.
The fight against aphids is to treat the plant with insecticides. You can resort to the popular methods, spraying the orchid with onion or tobacco-soap solution.
Sometimes in the ground or on the leaves of a flower small greenhouse spiders settle. It does not do any harm to the plant itself. However, spider webs inflorescence of orchids, spoiling the beautiful appearance of the plant.
No chemistry is required to fight spiders. You just need to carefully examine the flower, collect insects from it and wipe all the leaves to remove the web.
