Pest scale insect (Latin Diaspididae) - an arthropod animal belonging to the order Hemiptera. There are more than 2400 species in the Scale family.
Scabbards are capable of infecting both indoor and garden plants. What do scale insects look like? Their bodies are covered with a dense protective shell, consisting of two or one skin and secretory wax. The shield is easily separated from the insect. The mouth apparatus of the scabbard is sucking. Pest species differ from each other in color, size and taste. The danger of insects of this family is that their larvae, almost immediately after emerging from eggs, settle on the ground organs of the plant and begin to suck juices from them. Sheet plates can be completely covered with shields.
Scale larvae attach to shoots, trunks and the underside of plant leaves and feed on cell sap. With a strong occupation, the leaves seem to be covered with a bloom from the bodies of the scale insects, prematurely turn yellow and fall off, the shoots dry out, and as a result, the growth and development of the plant slows down.
On indoor flowers, scale insects and their larvae function all year round. These insects reproduce very quickly. Most of the representatives of the family reproduce by laying eggs, but there are also viviparous species. At the initial stage, the larvae of scale insects are very mobile, especially male flying individuals, which easily spread to neighboring plants. However, males live for several days, while females are able to reproduce and harm flowers for several months.
In the process of vital activity, the scale insects secrete pad - a sticky substance on which a sooty fungus settles, and this does not add health to the plants.
It must be said that scale insects are often confused with false scale insects - arthropod insects belonging to the same order, but isolated into a special family that unites more than a thousand species. The scabbards and false scutes differ in that the latter do not have a wax shell: their eggs and larvae are protected by the dry skin of females dying after laying.
How to determine that a plant is infected with scabies? At an early stage of development, scale insects move very quickly, and pests can only be detected through a magnifying glass. If you see rounded light or brown scales in the places where the cuttings of the leaves adjoin a branch or trunk, then you can be sure that these are adult scale insects. If you did not manage to detect the appearance of these pests in time, then with an increase in their population, a sticky liquid will start flowing from the plant onto the windowsill - fall, and then you should have no doubt that the plant is affected by scabies.
The following preventive measures will help you protect indoor flowers from scale insects:
How to get rid of the scabbard at home? The fight against scabbards is carried out in different ways. In case of minor damage, washing the plant under a warm (up to 45 ºC) shower can help, after which the scale insects are removed mechanically using an old toothbrush or a swab moistened with alcohol. However, it is impossible to remove the shield at one time, so after 3-4 days you need to inspect the plant and wash it again in the shower.
The next inspection is carried out on the 10th day: if you find pests, remove them mechanically and treat the plant with some folk remedy. On the 14th day, conduct a control examination.
If the scale insects spread to several indoor flowers at once, they resort to treating the affected plants with folk remedies, and if the degree of pest infestation is so significant that urgent and decisive measures need to be taken, use chemicals.
Folk remedies for controlling scale insects are not as radical as chemical ones, but they are also not as toxic, and if there are few pests on the plant or you decide to treat indoor flowers for preventive purposes, then it is better to use proven grandmother's methods. For example:
In the event that there is an urgent need to save the plant from scale insects, you need to use insecticides. The following drugs are effective against the scabbard:
In addition to the drugs described, they destroy the scabbards Tanrek, Confidor, Colorado, Iskra Zolotaya, Karbofos, Fufanon, Kemifos, Novaktion, Antiklesch, Alatar, Admiral and others.
Of indoor plants, citrus fruits, subtropical and tropical palms, begonias, cactuses, pomegranates and indoor roses are most often affected by scabies. The scale insect on the flowers of the Aroid family, which include monstera, caladium, calla, philodendron and spathiphyllum, is also quite common, like the scale insect on the leaves. ferns... But the most offensive thing is when pests infect orchids, these beautiful, delicate and by no means cheap exotic flowers. How to get rid of scale insects on an orchid? It is best, of course, to do without chemicals, but the choice of funds depends on how badly the plant is affected.
As soon as you find pests, wash the orchid under warm running water, trying to remove insects from its leaves and peduncles with a brush. Then you need to isolate the orchid from other plants, for example, by placing it in a greenhouse: scale insects do not tolerate high humidity well. If this is not possible, then simply put a transparent plastic bag on the plant, which will need to be removed for 20 minutes twice a day in order to ventilate the orchid and prevent it from getting burned.
The next step is to treat the plant with a folk or chemical remedy. Of the chemicals, the most effective are Aktara, Fitoverm and Aktellik. Of the folk remedies, a solution of olive oil, infusions of garlic, onion and pepper, a kerosene-soap emulsion and, finally, treatment of flowers with alcohol have proven themselves best in the fight against scale insects on orchids: types of orchids with thick leaves are wiped with a swab dipped in ethyl alcohol, and for thin-leaved species, treatment is used with a solution of 10 ml of ethanol in 1 liter of water, which is applied with a brush.
Homemade lemon can become infected with scale insects from nearby home plants, fruits, or bouquets of fresh flowers. The shield can enter the house with a gust of wind through an open window. You should be aware that if the air in the room is humid enough, the pest will not hit your plants.
If signs of the presence of scale insects still appeared, that is, the lemon began to grow worse, its leaves began to turn yellow and shrink, start pest control as soon as possible. First, try to collect all the scabbards by hand with an old toothbrush, then wash the tree under warm water in the shower, and then wipe the trunk and all the leaves (including the underside) with a cotton swab dipped in alcohol. Then spray the lemon tree with an insecticide and re-spray it after 10 days.
If a small number of scale insects have settled on lemon, you may be able to cope with them with folk remedies - soap-kerosene emulsion, onion infusion, a solution of olive or transformer oil.
Whatever you process the lemon, do not forget to protect the soil in the pot, and when the pest control is successful, change the topsoil just in case.
Scabbards can get on indoor ficus in the same way as on a lemon tree. The first sign of a ficus lesion with scale insects is a sticky coating on the leaves of the plant - honeydew, or honeydew, on which a sooty fungus appears very quickly. If you look closely, you can find whitish or gray-brown plaques on the trunk, branches and underside of ficus leaves - adult scale insects that feed on plant sap. Gradually, the surface of the leaves becomes uneven and ugly due to the growing new tissue, the affected leaves turn red, deform and eventually fall off. If the ficus is not treated, then in two years the leaves and branches on it will begin to dry out en masse, and the bark will crack. The most common scab is on Benjamin's ficus.
How to get rid of ficus from scale insects? Remove heavily infested leaves and, if necessary, branches. Then wash the plant and scrape off the ground parts with a brush or hard sponge. If there are few insects, use a folk remedy or a biological preparation such as Bitoxibacillin, but it is better to take the ficus out into the open air and treat it with a strong insectoacaricide. And even after that, it may turn out that not all the scale insects have died, therefore, after 3-4 days, inspect the ficus and if pests are found, wash the plant again and remove the scale insects by hand, and after another week, re-treat the plant with a chemical. A weekly inspection of indoor plants should be a must. Apply fertilizer in a timely manner and adjust the watering regime so that pests have no chance of settling on your indoor flowers.
The scale insect in the garden is as insidious and difficult to destroy as the pest species that live on indoor plants. Scabbards are distributed mainly with planting material, but there are other ways of infecting garden plants with pests.
Scabbards often infect currant and gooseberry bushes. Scale larvae hatch during flowering and immediately stick to shoots, branches and leaves. Young individuals are easily exterminated with the help of pesticides, but adult scale insects, reliably protected by a wax layer and a chitinous shell, are practically invulnerable to most poisonous drugs. The main way to get rid of garden plants from scale insects is mechanical cleaning with a metal or hard plastic brush. Leaves and shoots infested with a large number of pests are best removed and burned.
Chemical and folk remedies to combat scale insects are preventive treatments of the bushes. In early spring, before the start of sap flow, the plants and the ground under them are treated with a 3% solution of Nitrafen in order to destroy the larvae of the pest that overwintered in the upper soil layer and in the bark of the branches. Washing the branches of shrubs with a soft cloth with a soap-kerosene emulsion is effective, and this procedure should become as regular as watering.
The scabbard damages not only berry bushes, but also fruit trees, as well as garden ornamental plants, however, the methods of pest control on all these crops are carried out using the same methods.
There are many varieties of scale insects, but each species has its own food preferences.For example, cherry, cherry, apple, pear, peach, plum, ash, hornbeam, as well as privet and hawthorn can become victims of the pear yellow scale insect, while the pear red scale insect, in addition to stone fruit and pome fruit trees, affects walnut, horse chestnut and dogwood.
Fruit trees are harmed by such types of scale insects as yellow and red pear, comma, rose and purple. Ornamental trees and bushes are most often damaged by willow, poplar, rose and euonymus, and conifers - by spruce, pine and fir scale insects. Garden crops are preferred by the mulberry scale, eating eggplants, pumpkins, carrots, fodder beets, but it also applies to fruit and ornamental trees and shrubs. Indoor plants suffer from cactus, ivy, palm, orange comma and euonymus scale insects. We offer you a description of the most dangerous and most common species of this genus:
In addition to those described, in room culture, as well as in gardens and vegetable gardens, you can find the following types of scale insects: orange comma, European pear, red orange, brown, pine fusiform, thuja, thorny and apple comma.

A shield on houseplants, garden beds, or garden trees can cause a lot of trouble. These pests damage the leaves, trunks, fruits and branches of many plants. In the midst of the garden season, we fight the shield competently!
If you find small yellow-brown plaques on your plants, it's time to sound the alarm. Do not be fooled by their "frivolous" size - in agricultural regions, when some species of these crumbs are found, a strict quarantine is introduced. For several years, scale insects can destroy even a small tree, let alone your orchid or beet.
Scabbards are hemiptera insects that literally suck out all the juices from plants. There are several thousand species of them, and almost all of them are dangerous gluttonous pests. In addition, the overwhelming majority of scale insects are polyphages. They practically do not care what kind of plant to eat, hundreds of species are used as forage plants and the pest easily "migrates" from one crop to another.
The main danger for gardeners is represented by female scale insects - we see them on the leaves and branches in the form of tiny flat "turtles" that stick to the surface of the plant. They have a very durable shell that reliably protects insects from the effects of chemicals. In addition to the fact that the female scale insect actually feeds on the plant and lays clutches of eggs inside it, from which the same voracious larvae hatch, she also secretes a sweetish sticky liquid - honeydew, creating favorable conditions for the development of a sooty fungus (rabble).
Scabbards affect almost all types of plants - on the site, fruit trees with shrubs, and ornamental species, and garden plants equally suffer from them. Moreover, these insects damage absolutely all parts - from leaves and fruits to branches and bark.
In the garden and vegetable garden, plants can be harmed by the Californian scale insect, mulberry scale (white plum), comma-shaped apple scale, beet, acacia, hazel, purple, brown ...
Signs of damage to all types of scabbards are almost the same:
- the plant shows single, then a large number of rounded flat scales up to 5 mm in diameter (adult female scale insects) - in extreme cases, these "scales" can completely cover the branch or trunk of the affected plant
- sticky discharge appears on the surface of leaves and branches - pad
- small yellow spots appear on the plant, growing and turning into holes over time as the juice is sucked out
- the leaves turn yellow, curl, dry out and fall off
- ovaries and flowers prematurely dry out and fall
- branches are bent and bare
- fruits become stained and die off
- a sooty fungus is actively developing
- the plant stops growing, dries up.
Saplings and young trees are especially affected by the scale insect.
In an apartment, the danger of scale insects is aggravated by the fact that, in favorable home conditions, they can reproduce all year round, without a dormant period in the cold months. The process of changing generations (and therefore eating plants) goes on continuously.
Scabbards can enter the apartment together with new plants brought from the store by contaminated soil and even be carried by the wind (at the stage of vagrant larvae). In the future, the females attach to the leaves and begin to do their dirty work, and the mobile larvae easily migrate to neighboring plants.
As in the garden, in indoor conditions, scale insects affect almost all types of plants, even those that are poisonous to most other organisms. Especially they "like" palm, bromeliads, citrus fruits. In an apartment, you can equally successfully find a scabbard on a ficus, lemon, ivy, orchid, cyperus, asparagus, bastard, cactus ...
Further, in damaged plants, everything goes according to the above-described algorithm: yellowing, drying out, dying off ...
Found at least one scabbard plaque on flowers, vegetable leaves, or tree branches? Do not hesitate - if you miss the initial stage of damage and do not take timely measures, then you can lose not only the future harvest, but also the plant itself!
How to get rid of scale insects on plants? If the insect plaques are still in single copies, consider yourself lucky. The simplest mechanical method can help - the plant is isolated from the rest (of course, when it comes to indoor flowers), and the sucked females are simply brushed off the surface with a soft toothbrush or cotton pad. After that, it is advisable to thoroughly wipe the whole plant with a cloth dipped in soapy water, and rinse the solution with hot water, and then repeat the rubdown with a shower a couple of times with an interval of a week. In addition, the nearest plants should be treated, as well as the windowsill or shelf where the affected plant stood (they can be wiped with any alcohol-containing solution).
In the garden, the affected branches (foliage, bark, lichens from the trunk) must also be removed mechanically - for example, on a lined film or paper - and then the removed parts must be burned.
The most important stage in the fight against the scale insect is the prevention of mass infection - regularly and carefully inspect your plants for the appearance of insects and traces of their vital activity (egg laying, sticky honeydew), not forgetting to look at the back of the leaves and in the leaf sinuses.
If there are already a lot of sucked scale insects, it is no longer possible to simply remove insects and parts damaged by them. It will be necessary to destroy especially damaged specimens, and to apply chemical measures to combat the scale insect for neighboring plants.
Surface single spraying in most cases does not give a positive effect - the shield reliably protects the insect's body from damage. Therefore, if it is not possible to regularly wipe the plant with material soaked in soapy water or insecticide, the spraying treatment will definitely have to be carried out several times - at least three times, with an interval of a week, in order to guarantee the destruction of the generation of pests newly emerging from the eggs of larvae.
As an effective remedy for the scabbard, the drug "Aktara" is often advised - a contact insecticide of the neonicotinoid group, whose protective effect lasts up to a month. The best effect will be given by simultaneous spraying with this substance plus root watering with a solution.
In addition to "Aktara", the following drugs help from the scabbard:
- organic pesticides, neonicotinoids, which block the transmission of nerve impulses in insects (Apache, Mospilan, Tanrek, Iskra Zolotaya, Konfidor, Colorado, etc.)
- juvenoids - synthetic analogs of insect hormones that disrupt their metabolism (for example, Admiral, Phasis, etc.)
- organophosphorus compounds of intestinal action (Karbofos, Aktellik, Alatar, Kemifos, Antiklesch, Novaktion, etc.).
Most of the above drugs are highly toxic, so strictly observe the dosage indicated on the packaging and the technology of their use, and also do not neglect the safety precautions during work.
Among the folk remedies for the scale insect, you can find mention of the treatment of affected plants with fleas and ticks, onion and garlic infusions, vinegar solution and even vegetable oil and vodka. Of course, all of them are not as toxic as the above drugs, however, there is practically no benefit from them for plants. These funds will help get rid of the scabbard only at the very first stages of the defeat and subject to repeated processing. In the worst case, with inept use, you can completely harm the plant - cause clogging of pores or burns on the leaves, for example.
The scabbard is a dangerous and indiscriminate pest. However, with the observance of preventive measures and the timely use of appropriate drugs, it is quite possible to free your site from this ubiquitous insect.
The scale insect is characterized by pronounced sexual demorphism - females and males differ quite strongly. On plants, it is mainly females that can be seen, since males live for a short time - only before mating, after which they die.
If we look at the photo of an insect, we can reveal that the female scale insect lacks wings, legs, eyes and antennae, but there is a well-developed oral system, which has a piercing-sucking type. After the female is born, the first few days she has a soft shield and can move.
After puberty, its scutellum becomes rigid and the insect no longer moves, but simply feeds on juice in one place. The oval or rounded body of the scabbard can measure from 1.5 to 2 mm, in some cases, their size can reach 5 mm. The color of the scutellum of different types of parasites can differ - from light yellow to dark brown.
As for the males, when studying the photo, you can see that their oral apparatus is reduced, there are eyes, as well as fully formed wings and limbs. Males are white in most cases, but they can also have a different color - light orange, red-gray or red.
The scale insects are distinguished by a multi-stage life cycle, consisting of several stages, during which the larva develops and matures, which later turns into an adult.
After puberty, the main task of adults is reproduction. After mating, the female bears eggs for 3 months, feeding on plant sap. After this period, she produces a clutch of eggs on the plant. Unlike a false shield, one castle can lay up to 500 eggs. After hatching of the larva from the egg, its development proceeds according to the scheme presented above.
A shield on indoor flowers is a huge problem for all florists. These parasites can cause enormous damage to the plant and lead to its complete destruction. For example, a scale insect that has started up on fruit trees can achieve its complete destruction in three years, if measures are not taken in time and do not begin to fight these small parasites.
If the scabbard is started on an indoor plant, then in the shortest possible time it destroys it completely, if the plants are not treated with special agents and poisons. Parasites can enter the house with infected flowers from stores or with planting soil, so you need to try to exclude such causes of infection.
A sign that the scabbard has already appeared on the flowers and it is necessary to treat it as soon as possible is evidenced by the following list of lesion symptoms:
When populations of parasites appear on indoor plants, flower owners immediately have the question of how to deal with the scale insect on indoor plants in order to overcome parasites and not damage the flower itself.
Today, there are various methods and measures that can effectively solve this problem. Mostly used are chemicals or folk remedies.
Today there are no special products that remove the scabbard from the plants, but there are many different insecticides used for aphids and other insect pests, which can also be used to get rid of the scabbard of ornamental plants.
The preparation Fitoverm from the scabbard, among other insecticides, differs in that it destroys many different parasites on indoor plants. It can also effectively fight the scabbard. An insecticide is a biological drug that can quickly kill the entire population of the parasitic scale insect.
To process plants with Fetoverm, you need to dilute 2 ml of the substance in 200 ml of pure water. After that, the flower is treated with a hand sprayer. To completely destroy parasites and cure the plant at home, the treatment should be carried out 3 ... 4 times. After the last treatment or after the next spraying, it is necessary to use not only Fitoverm, but also Epinin, which will support the plant.
Aktar's scabbard remedy is another effective insecticide that allows you to quickly destroy the scabbard and cure the flower at home. To remove parasites, a solution should be prepared from the actara using 1 g. substances per 1.25 liters of pure water. In addition to spraying, the soil of the plant is also watered with a solution that is prepared in the calculation of 1 g. actars for 10 liters of water. Carrying out procedures 2 ... 4 times every 10 days will destroy all living specimens of the scale insect and cure the flower.
An effective treatment will be obtained if the plant is treated with Confidor. To rid yourself of these harmful parasites of domestic plants, you need to spray them with a solution that is prepared in accordance with the following proportion: 1 gr. the drug must be diluted in 500 ml of water.
After 3 ... 4 hours, the scabbard dies and the pest will be finished completely. The remaining corpses are removed from the plant using moistened gauze. It is important that Confidor destroys only parasites - it does not affect the plant.
Actellikt is a potent scabbard remedy that will allow you to get rid of the pest in difficult conditions, when the situation is neglected and it is very difficult to cure the plant. To quickly defeat the insect, dissolve one ampoule of the drug (2 ml) in one liter of water and spray the plants. You can perform no more than 3 treatments in a row - the waiting period is 3 days.
To fight insects with this tool, you need to perform all procedures only outdoors. Pregnant women and those who suffer from allergies are prohibited from working with the drug.
As you can see, fairly simple measures with the use of modern insecticides will quickly defeat the scabbard and prevent its reappearance.
For those who are looking for a way to get rid of scale insects on indoor flowers without chemicals, there are several alternative methods.
Soapy solution can effectively fight indoor plant parasites. To quickly prepare a solution for processing, you will need laundry or tar soap, which can be diluted with a glass of water. Using a soapy solution, spray the plants or wipe them with a dampened cloth and try to remove all insects from the trunk and leaves.
This is a rather laborious process, but it will allow you to quickly remove parasites and save yourself from the need to use chemicals. After wiping the plants, it is recommended to remove the remaining soap foam on them with a damp cloth or rinse with cold water under the shower.
Chemical preparations for scale insects are effective, but folk remedies can also effectively fight and quickly remove parasites from plants. One of the simplest methods is to use a mixture that includes a soapy foam solution and oil. This can be 15 ml of regular machine oil or 2 tablespoons of sunflower or olive oil.
With the help of the resulting emulsion, you need to process the leaves and stems of the plant, wait 6 ... 10 hours and then wash off the rest with cold water. Processing with such a solution can also be carried out as a prevention of the appearance of the scabbard in the future.
The list of folk remedies that can effectively solve the problem of how to deal with the scabbard on indoor plants includes garlic tincture. To prepare it, you need to take five ground garlic teeth and pour them with a glass of plain water.
It should be insisted for one or two days, after which the solution must be filtered, and it will be possible to use it to treat the affected plants. With the help of the prepared suspension, the prevention of the appearance of the scabbard can also be carried out.
Scabbard control is an important process that will allow for effective treatment of an infected home plant. All methods are good for this - both with the help of special chemicals and folk methods. The latter are also good because these methods can be used as prevention of the appearance of parasites.
Everyone has the right to choose the remedy that is most effective for him. Above is a wide list of methods on how to remove the scabbard. None of them will provide the desired result if, in parallel with the treatment, the causes that led to the infection of the plant are not removed. Only in this case can you count on success and ensure that re-infection for one reason or another does not occur.
It is necessary to start fighting pests on indoor plants as soon as possible after they are detected. This will save the sick citrus and prevent infection of the rest of the green "pets".
The lemon shield can be destroyed in several ways. It is important to know for sure that this particular pest has settled on citrus, a mistake can lead to a disastrous result: the wrong "treatment" threatens the death of your tree.
The scabbard (in Latin "Diaspididae") looks very peculiar. A photo of an insect, enlarged several times, makes it possible to understand: the pest knows how to disguise itself perfectly. In fact, it is a small worm of the Chrysomelidae family, reckoned with the genus Cassida. They are widespread throughout the world.
On the territory of Europe and Russia, up to five dozen species of scale insects can be found, both Cassida riebalosa (popularly - an earth bug) and citrus coccida (red orange) and other species, including a false shield, can live on a lemon, bringing no less harm to plants ...
The pest looks like a bug outwardly (the photo allows you to make sure of this). An adult grows up to 1.5-2 millimeters, its body is oval, convex, rusty-brown with a black abdomen, which does not have a clear division into the head and chest. Females are wingless, covered with an easily detachable shield. For females in the imago stage, an immobile lifestyle with continuous feeding is characteristic.
Males are few in number compared to females, they have wings, and their body size is somewhat smaller.
The fight against scale insects on lemon is complicated by the fact that insects reproduce quickly. It grows from two generations in a year. Females lay many eggs under their scutellum. After the young growth comes to the surface of the plant. A characteristic feature of this type of pest is the mobility of the larva at the first stage of development, for which biologists called them "vagrants".
This period is the most favorable for the spread of the pest, insects crawl over decent distances, colonize neighboring houseplants. As they grow older, the larvae lose their ability to move and become sedentary.
The female larva grows, loses its eyes, legs and antennae. And future males stop feeding in the larval stage. They grow wings. The life of an adult male lasts three days, during which time he fertilizes the female.
If the scabbard starts up on a lemon, the tree is in danger! Coccids, without exception, feed on proteins that plant juice contains. This becomes the reason for the disruption of assimilation processes and affects the appearance of the citrus. If the fight is not started with the pest in a timely manner, the leaves of the indoor lemon begin to die off, individual branches, in the end, and the tree itself can die.
The sugar in lemon juice is processed by the parasite into sweet honeydew. Nature has provided that the bug itself does not stick to its own secretions. Special glands simply shoot out droplets of honeydew, they fall everywhere: on the plant itself, on the glass, window sill, walls and floor.
This, in turn, attracts ants, which is so important for private homes. Sugar discharge on the trunks of a lemon bush can become a place of settlement for saprophytic fungi, and this leads to the appearance of honeydew or rabble.
Poisonous substances injected by the pest disrupt photosynthesis and stop the growth of citrus.
The unfavorable conditions that are created for the lemon are considered the cause of the appearance of scale insects. Coccids prefer plants weakened and over-fertilized with nitrogen for parasitizing.
Most often, the pest begins an attack in the winter season, when a pot with a pet is placed closer to a warm radiator and away from freezing windows: a lack of light and an abundance of heat are ideal conditions for the parasite!
A change in conditions can destroy the usual consistency of juices in the plant, and this provokes abundant reproduction of the parasite.
How to understand that a lemon needs treatment? Examine it carefully to find the shield. It looks like a small growth that infects the leaves and stem of a plant. Oval immobile brownish plaques (on the enlarged photo you can see the carapaces), abundantly covering, mainly, the inside of the lemon leaves - this is the parasite.
To get rid of the scabbard, you need to fight it! She herself will not go anywhere, but, on the contrary, will multiply, and then all the home flora will have to be treated! Pest extermination is not so difficult and requires, however, a systematic approach and certain skills.
Do not exclaim: "No matter how I get rid of the parasite, I have not completely removed it!" The scabbard is an excellent concealer, and even single unnoticed individuals will breed again. Therefore, get ready: a one-time treatment is unlikely to be enough.
Many people prefer to use insecticides, since it is quite simple to deal with the scale insect on a lemon in this way. Despite the fact that the chemicals destroy the pest with a bang, it is dangerous for fruiting plants to do this treatment. And not all household members easily endure the "chemical fight".
Preparations help to quickly get rid of the insect and larvae:
To destroy the pest, the plant should first be mechanically removed from insects, then with an insecticide solution prepared exactly according to the instructions, the aerial part of the bush should be treated. It is recommended to use personal protective equipment, since the drugs have a certain level of toxicity. After the completion of the work, the room where the treatment took place must be ventilated.
It will not be superfluous to replace the top soil layer in the pot - eggs and pest larvae may remain there. Re-process the lemon after a couple of weeks.
How to get rid of scale insects on lemon by hand? Use cotton pads, a toothbrush, or a sponge. With their help, the leaves are cleaned using a soap solution.
It is very simple to prepare it. Laundry soap is dissolved in water until the solution has a stable opaque color. Then the insects are cleaned off with a sponge or brush dipped in the solution.
It is imperative to remember when the hostess processed the plant, since the repeated procedure must be repeated in a week.
Is there a way to kill a bug without using chemicals?
Traditional methods will help with this:
"People's" struggle is advisable at the initial stage of citrus infestation. With abundant reproduction of the scale insect, it is better to go straight to chemicals.
Since it is not easy to get rid of the scale insect on lemon, you need to prevent its mass spread on the plant, and at the first signs of defeat, start fighting the pest. To avoid the appearance of the parasite, it is necessary to exclude infested flowers from entering the house, as well as create conditions that will be comfortable for the home citrus.
It is important that the pot is placed in a sufficiently bright, but not hot, place. The land in it should be regularly loosened, watered moderately and not abuse nitrogenous fertilizing.
On indoor plants, you can get rid of the scale insects by removing pests with a cloth or damp cotton wool. It is recommended to moisten cotton wool with vodka or alcohol. On garden plants, in most cases, mechanical cleaning of the bark is carried out using brushes with metal bristles. Thanks to this, you can destroy the shields, including the eggs that are hidden under them. If there are areas that are strongly affected by the scabbard, then it is advisable to remove such shoots and burn them.
Pests that have appeared on young seedlings should be removed mechanically, and also washed with laundry soap. At the same time, it is advisable to spray the top soil with toxic agents. If necessary, you can even carry out a complete replacement.
Chemicals vary. They can be professional or folk.
Most folk remedies involve the treatment of plants with a variety of substances:
1) tincture of garlic or tobacco
The use of such methods can bring certain results, but their application is a rather dubious decision. This is due to the fact that these methods have a number of negative factors that can harm the plant. So tincture of garlic or kerosene can lead to leaf burns.
The use of oil, as well as other fat-containing substances that create a film on the leaves, is also dangerous, because they clog the stomata of plants. When the stomata are blocked, the plant does not have the opportunity to breathe, as well as to carry out photosynthesis. This applies primarily to plants.
A soap solution along with a mechanical method can be a good remedy, but after a few hours the plant will need to be rinsed with water.
They can be of different types:
1) hormonal to inhibit the growth and development of larvae
The biological method consists in infecting insects with a specific virus. These viruses infect only insects, however, to use this method, it is necessary to have access to viral material, which can only be provided by special laboratories.
Newly acquired flowers are carefully examined. Suspicion is caused by:
New plants are kept in quarantine for 14-15 days, maintain good light and humidity. To do this, place a flower in a greenhouse or greenhouse. Light and abundance of moisture are unattractive for scabbard breeding. For processing the leaves, growers advise Neem oil, which is obtained from the seeds of the same tree, which resembles an olive. The active ingredient is sulin, which shows a strong repellent effect.
Using scabbard preparations on fruit and other trees, you need to carefully process them and prevent reappearance.
Prophylaxis can be used as an initial method for removing parasites:
These simple methods protect the site from the scabbard misfortune. Periodic inspection of the plant will prevent parasites from multiplying and will help preserve the crop. Fighting the scabbard is not an easy task, however, comprehensive control measures have a noticeable effect and allow you to achieve good results.
