How to permanently get rid of scabies on indoor flowers
What does this insect look like? This is a tiny creature that can destroy even a large tree. His body is covered with a dense protective carapace, so the scabbard can be mistaken for hard growths on a plant. No wonder the scabbard has a second name - a garden turtle. But they are not at all as harmless as it might seem at first glance. In a couple of weeks, gluttonous creatures will destroy any plant.
Each gardener should be well aware of what the scale shield looks like on indoor plants, how to fight. The photo shows us females up to 5 mm in length. It is they that are found motionless on plants and look like droplets of frozen resin. Males do not grow more than 3 mm and move freely through plants using legs or wings.
Reproduction and life cycle of the insect
Most pests lay their eggs, but there are also live-bearing representatives of this family. They live on the lower and upper surface of leaves, shoots and trunks of plants. Scabies are settled at the larval stage of the first age. After leaving the shell, they creep in different directions, few are fixed on the same plant. Most of the larvae on the street are carried by the wind over great distances, some die.
The path of development of the insect in the larval stage depends on gender. The larva of the female develops, losing limbs, antennas and eyes, but retaining the oral apparatus. Shedding occurs two, occasionally three times. The male larva secrete a wax coat, through which a thin cocoon, or scutellum, forms on its body. Protected in this way, it molts, losing its mouth and legs. During this period, the limbs are formed in the male and the front wings grow. As for the oral apparatus, it is not restored.
A sexually mature male lives only a few days. During this time, he must find the female and fertilize her. The reproduction of the vast majority of pests occurs along the path of parthenogenesis. In some species of scale insects, males sometimes appear, but fertilization is not necessary to continue the genus. There are species that have completely lost males.
Varieties of scale insects
Like most other insects, scale insects in the world fauna are represented by a great variety. Mulberry (white plum), violet, pseudo-Californian, apple spotted, tropical polyphagous - these are just a few varieties of these half-winged. In total there are more than 2400. The table provides general information about some of them:
|Types of Scabies||Body length mm||Features|
|Mulberry||Pseudaulacaspis pentagona||2||This is one of the most common types of parasite. The mulberry scale has a wide habitat. It is the most dangerous enemy of many fruit, ornamental and forest crops. In our country, mulberry scale insects were included in the list of quarantine objects.|
|Willow||Chionaspis salicis L.||11||Distributed in the European territory of Russia, in Western Europe. Willow scale affects not only willow. Favorite food of willow scale insects - aspen, alder, poplar and other deciduous trees.|
|Californian||Quadraspidiotus perniciosus||2||This member of the family is a polyphage and is found everywhere, damaging over 200 plant species.|
Which house plants are at risk?
Most often, insects settle on such plants:
- ficuses of all kinds;
- palm trees, especially fan;
- citrus fruits;
Hibiscus, dracaena, oleander, yucca, anthurium do not leave insects with their attention. Damaging the protective shell, pests contribute to the fact that fungi easily penetrate through the wounds in plant tissues.
To defeat the infection, indoor flowers are treated with the biological product "Fitoflavin", which destroys almost all fungal diseases. Dosage - 2 ml per 1 liter of water.
Reason for occurrence
Everything is clear in the garden: young females and males fly freely and cover decent distances. And how does a scale shield appear on indoor plants? How to fight? Photos of effective drugs will be considered a little lower, but for now we will consider ways of penetrating your home. This is usually soil, plant debris and water. And most often parasites come to your house with new plants.
They usually begin to fight with a mass appearance, before simply not noticing. And therefore, a new generation of scale insects spreads over neighboring pots. And only a sudden, massive dropping of leaves, inhibition of growth or death of plants can be a signal for the owner, that it is time to show maximum care.
Scabies on indoor plants can appear regardless of how well you care for them. Moreover, it affects any plant, including succulents. But this pest also has pets that are attacked in the first place. We are talking about orchids and laurels. Do not bypass the palms and ivy. It is with great pleasure that the scutellum regales with cyperus, aucuba and other exotics. Under attack and the usual domestic inhabitants: chlorophytums, geraniums and hippeastrum.
What is noteworthy, the pest most often appears in winter and early spring. This is evidenced by numerous amateur photos. How to deal with scale insects on indoor plants? It is necessary to engage in increased immunity of landings. Indeed, at this time, the plants are most weakened, which becomes a decisive factor for the pest. It is much easier for them to harm flowers that are not capable of resisting. Therefore, follow the recommended conditions, and closer to spring, apply special immunostimulants to the soil. It can be inexpensive succinic acid.
Signs of defeat
Insects harm garden and indoor plants. You can bring the pest with a bouquet or bought a new flower. At home, flowers die in a couple of months. Fruit trees are destroyed in three years.
What are the features of the manifestation:
- Yellow tubercles in the form of chlorosis appear on the upper surface of the leaves. Reminiscent of grain;
- The spots increase in size, the leaves turn completely brown or yellow;
- A pad stands out - a sticky liquid on which pathogenic fungi and dust linger;
- Gradually, the stems and leaves fade, deform, dry out;
- Flowers, ovaries and fruits fall;
- Growth stops, the plant dies.
With secondary infection on the vegetative parts, a dangerous soot fungus additionally appears, which also requires treatment.
Phalaenopsis, cymbidium and sympoidal orchids are the most favorite plants for scale insects. Pests actively eat the juice of fleshy thick leaves. Sinuses and wraps of pseudobulbs are affected.
The most common types of pests are:
- Hemispherical false scale. One individual gives more than 2000 new parasites. Grow to 4 mm, painted in dark color;
- Palm scale. Small sizes up to 1 mm. Scutellum oval, light brown;
- Soft false shield. Females are viviparous and at the same time bring up to 1000 new pests.
If a scab has appeared on orchids, the plants grow weaker, turn yellow, wither due to photosynthesis disorders. On examination, you can see:
- Yellowish and brown spots that increase in size;
- Yellowing and death of leaves;
- Voids in the affected areas;
- Sticky adhesive and moldy deposits.
Of folk remedies for cleaning orchids, fern broth is used. 10 g of dry leaves are poured to the top with water, insist 20 hours. Boil for 30 minutes, cool and spray the shoots of orchids. Broth of fern irrigate bushes daily for one week.
To wash off the pad, wash the leaves with warm, soapy water. They remove the dry upper wrapper of pseudobulbs, where pests especially like to hide. In the initial stages, you can catch the shields with sticky adhesive tapes for flies. But they need to be replaced daily, even in the absence of obvious traces of pests.
It is better to refrain from using insecticides on lemon. Citrus farmers consider a soap solution with 5 drops of kerosene per 1 liter of water to be the best way. A film of soap blocks the access of air for scabs, kerosene, falling on the body of pests, acts like poison. The solution is completely treated with citrus, washed off with water after 3 hours.
In order for the plant to recover from stress faster, it is fed with the Epin biostimulator. The drug for treatment is applied by spraying.
Scalp plants are removed manually. Use a sponge dipped in soap-kerosene solution. They scrape off the branches with a knife. Shoots, leaves of ficus Benjamin and other species affected by scabies are removed. At the same time, chemicals are used 3–6 times at weekly intervals.
Processing plants against scale insects gives the result if complex measures are applied. Start with washing with warm water, soapy solutions. If the size of the plants allows, arrange a mini-greenhouse, covering the plant with a plastic bag. Spend manual processing, removing the scab.
Only chemical treatment will bring a temporary result. Larvae perish, and many adult scale insects, covered with shell, survive. New larvae will soon emerge from the eggs.
A scale shield appeared on a room palm; it flows with a sticky liquid. How to cure her?
I washed my plants under warm water, right from the shower. But we must make sure that water does not fall. If the leaves are large, you can simply wipe them with a damp cloth. If there are severely affected leaves, they can be removed. After it dries, treat it with any active anti-scale agent. I used Fitoverm, it is less harmful to people. After some time, processing must be repeated. Through which one, it will be indicated in the instructions for the selected tool. The topsoil is recommended to be replaced, but I did not do this. But I think it will not be superfluous.
If brown plaques are found on leaf blades, petioles, sinuses, the bush with a scab should be immediately isolated so that the pests cannot move to healthy flowers. Check all the plants in the collection in the neighborhood. How to deal with scale insects on indoor plants:
- Apply chemicals with an insecticidal effect. Multiplicity of application 2-3 times, the interval between treatments 7-10 days;
- Perform mechanical washing with soap and detergent solutions;
- Prepare folk remedies based on garlic, onions, soap, alcohol;
- Spray veterinary flea products for pets.
Mechanical method of destruction
This is the safest way to fight parasites. Need to:
- dissolve grated soap in warm water;
- cover the soil with polyethylene;
- gently wipe the sticky leaves and trunks of the affected flower with a cotton pad moistened with soapy water;
- re-walk through the treated areas with a cloth with a rough texture, such as a waffle towel;
- rinse off the soap solution with running water.
One procedure is not enough for the final disposal of insects. It must be carried out at least 4 times a month.
When all the moisture has evaporated from the leaves, it's time to start processing the plant. To completely destroy the scab from indoor flowers will help insecticides of chemical origin. They show good results, but produce a toxic effect on the human body. Therefore, you must be extremely careful when working with chemicals: follow the instructions exactly and do not neglect important safety precautions.
After processing the plant, the room must be well ventilated so that the insecticide vapor disappears.
“Fitoverm” and “Aktaru” are referred to the basic preparations from scale insects on indoor plants. They are easy to use and have proven themselves in action, becoming the favorite insecticides of many gardeners.
But sometimes their actions are not enough. And, if the treatment did not bring the desired result, more toxic drugs will come to the rescue:
- Inta-Vir, Confidor, Tanrek;
- “Actellik”, “Vermitek” and “Karbofos” are used if infection with scale insects has become widespread. Processing with these products can only be done outdoors, with gloves and a respirator.
Their list is given as toxic properties increase.
The drug is the most mild exposure, almost safe for humans. Therefore, experienced flower growers are advised to start the fight against the pest precisely with Fitoverma. To prepare the working solution, you will need to dilute 2 ml of the chemical in 200 ml of water. With this composition, the plant is sprayed from all sides from a conventional spray gun. A total of 3-4 treatments will be needed to completely get rid of the pest.
A powerful systemic insecticide that destroys most pests of indoor plants. The solution, prepared at the rate of 1 g per 1.25 liters of water, is suitable for spraying the green part. This amount is enough for 20-30 home flowers, depending on their size. “Aktara” needs to be shed and the soil: for this, 1 g is diluted in 10 liters of water (standard bucket). As practice shows, 2-3 procedures are enough to eliminate the problem of pest infection of indoor plants.
Scale larvae emerge from eggs gradually, so plants need to be treated until the pest is completely destroyed
An enteric-contact insectoacaricide effective against scale insects, pseudomonas, thrips, aphids, whiteflies, Colorado potato beetles, cabbage whites, spider mites, etc. It is considered one of the most powerful non-systemic insectoacaricides for the treatment of indoor and garden plants.
The active substance is pyrimiphos-methyl. The duration of the protective effect in the open ground is 3-10 days, in the closed - 10-12 days.
The main disadvantage of the drug is a strong pungent odor that lasts after treatment in the apartment for another 1-2 days. The hazard class for humans is 2, for bees and fish - 1.
An insect-and-acaricidal preparation of intestinal and systemic action, used to protect horticultural crops from pests, as well as to kill domestic insects: aphids, whiteflies, thrips, scale insects, false shields, worms, ticks, cockroaches, bedbugs, etc.
The active substance is pyrimiphos-methyl. The product is highly toxic, so it is not used during the flowering period.
Contact-intestinal insecticide against sucking and gnawing pests: scale insects, Colorado potato beetle, bear, etc.
The active substance is bensultap. The drug remains effective even at high temperatures. It does not have a pungent odor. In addition, it has a powerful effect on pest species relatively resistant to insecticides. It has a low level of toxicity.
An enteric-contact insecticide from the group of pyrethroids, effective against scale insects, aphids, whiteflies, Colorado potato beetles, cherry flies, weevils, tea moths, leaf-eating caterpillars, etc.
The active substance is cypermethrin. The drug, diluted in water, decomposes under the influence of the environment within a month. In light soil it lasts up to 2-3 weeks, in heavy soil - up to 10 weeks. When sprinkling the surface of the soil lasts 2 weeks.
Sometimes the use of insecticides is impossible due to allergic reactions, bronchial asthma and other diseases. In this case, folk methods come to the rescue.
Most often used against scale insects:
|Name||Cooking method||Features of use|
|A solution of kerosene and soap||Grind and dissolve 40 g of laundry soap in 1 liter of water. Add 5 ml of kerosene to the soap solution. Shake everything well||The mixture is used to wipe or spray infected sites on the plant.|
|Onion solution||Chop the medium-sized onion, grind and pour 200 ml of water. Leave to brew for 3 hours||Wipe all parts of the plant every week with the resulting solution. After pre-cleaning the solution, it can be used for spraying|
|Oil emulsion||Foam 10 g of soap in a glass of water. Add 2 tbsp. l olive oil and shake thoroughly||Fully cover the plant with an emulsion and leave for 6 hours, then rinse off the rest of the product. Conduct 2-3 treatments every 7 days. Oil emulsion can not be used on pubescent plants|
|Pepper infusion||Grind 50 g of fresh hot pepper and boil in 0.5 l of water. Leave to stand for a day and strain. Dilute 10 g of infusion in 1 liter of water, add 5 g of laundry soap||Treat the resulting solution with the plant once every 2 weeks|
|Soap-alcohol solution||1 tbsp. dissolve any soap in a glass of water, add 1 part alcohol and bring the resulting volume to 500 ml, adding pure water||After processing the flower, leave the product to act for 15 minutes. Then wash off the rest of the solution with clean water. On tender plants, this solution is not used, since there is a high probability of severe burns|
|Tobacco infusion||Mix 80 g of dry tobacco with 1 liter of water and leave for a day to brew. Then strain||The solution can be sprayed with infected plants or used for washing.|
|Garlic infusion||Grind 5 cloves of garlic and add 200 ml of water. Leave to brew for a day||Use the mixture to wipe the plant. If you need to spray a flower, then strain the solution through a triple layer of gauze|
All home remedies can be used at the initial stage of infection of the plant. With a massive lesion with scabies, folk recipes are ineffective, and in this case it is necessary to use modern insecticides.
Propagation of scale insects on garden trees
Females of the Californian scale insect immediately lay up to 140 live oval-shaped yellow-lemon larvae. Having grown up a bit, strollers actively begin to move along the branches of the plant. Driving the proboscis into the bark, they secrete a wax secret in the form of threads that stick around their body and gradually harden, becoming a gray shell. After 10-12 days, the cover is discarded during molting, the larva passes to the next stage of growth. When cold weather sets in, the carapace becomes denser and turns black. In winter, you can find larvae of the first and second age, as well as already adult reproductive females, scaleflies on plum and other trees.
Propagation of scale insects on garden trees.
With the onset of spring heat, with the beginning of sap flow, all generations of scale insects wake up and are ready for vigorous activity. Larvae settle on all branches, leaves, shoots on a tree. Larvae feed on plant sap, sticking to its leaves. This time is ideal for the main stage of pest control.
The scale shield on the apple tree and other fruit trees is capable of completely covering the trunk and branches, due to which the damaged bark dies, the diseased leaves fall, and thin branches dry out. Ill trees are more easily affected by other pests: bark beetle and black cancer. On felt cherry, they can damage all small shoots and leaves in a few days.
Note! The spread of insects between the trees occurs through the crawling of “tramps” larvae along closed branches.
Fighting the scallop on the currant and gooseberry
Scale in the garden is just as insidious and difficult to destroy, as are the types of pest that live on indoor plants. Scalp spread mainly with planting material, but there are other ways to infect garden plants with pests.
Scabies often affect currant and gooseberry bushes. Scale larvae hatch during flowering and immediately attach 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 chitinous shell, are practically invulnerable for most toxic drugs. The main way to rid garden plants of scabs is mechanical cleaning with a metal or hard plastic brush. Leaves and shoots inhabited by a large number of pests, it is better to remove and burn.
Chemical and folk remedies for the control of scale insects are preventive treatments of bushes. In early spring, before the sap flow begins, the plants and the soil beneath them are treated with a 3% Nitrafen solution to destroy the pest larvae that have wintered in the upper soil layer and in the cortex. Washing branches of shrubs with a soft cloth with a soap-kerosene emulsion is effective, and this procedure should become as regular as watering.
Not only berry shrubs, but also fruit trees, as well as garden ornamental plants, damage the scale, but the methods for controlling pests in all these crops are carried out by the same methods.
Pest Scale on the apple tree
Not every summer resident wants to use chemicals in the fight against pest. There are several effective non-chemical methods in the arsenal:
Shield on the apple tree
- Predatory insects. Ladybugs and wasps - parasites eat insects and fly away from the site.
- A few teaspoons of liquid soap is mixed with 3.5 liters. water and carefully process the whole tree. And after half an hour they pour it from the hose, but only with warm water and over the entire height, in order to wash off soapy stains and not harm growth.
- Decoctions. Wood ash (300 g per 1 liter) is boiled for 30 minutes and mixed with 10 liters. water. Fern (1 kg. Of fresh plant) is infused per day in 10 liters. water and cooked for 30 minutes, and then carried out daily spraying for a week.
- Infusions with soap. Garlic or bitter pepper is used as an additional ingredient. Garlic in the amount equal to the amount of soap, and water - three times more. Spray once every 3 days. Pepper (100 g per 1 liter) is boiled for 10 minutes and insisted for a day. Soap is added in a proportion of 1 part of pepper and 1/2 soap solution. Be sure to then wash the tree in a day.
- Infusion of celandine. A fresh plant (from 3 kg) is kept in water (10 l) for at least a day. With this tool, you can not only spray the apple tree, but also water the soil around it. Then the pest will disappear faster.
- Nime oil. It is inexpensive, equated to folk methods and can be used several times a season for the prevention and treatment of plants.
In the extreme case, when the problem is very extensive, cuts of the bark are made, the affected leaves and branches are eliminated - not only from the tree itself, but also from the trunk circle. It is important to carry out autumn cleaning when the insect scab has laid eggs and is ready for wintering. A metal brush is suitable for an adult tree (more than 5 years).
- Confidor (non-toxic to humans).
The protective properties of chemicals are improved if they are applied not only by spraying, but also into the soil.
Methods of dealing with scale insects in the garden
It is very difficult to exterminate the scale shield, because adult individuals are protected by a strong chitinous shell, and most toxic chemicals do not act on them. As a result, they can only be cleaned manually from the bark of trees.
The scab on the plum, on the cherry and other fruit is scraped from the bark using a metal brush or a special scraper, and adult females must be destroyed along with the laid eggs. With severe irreversible damage, the dead branches are trimmed and burned.
Methods of combating garden scale insects.
On seedlings, scabs discovered by scabbard are removed mechanically, and branches are additionally washed with a solution of laundry soap. Similarly, they fight the parasite on decorative indoor plants.
But young larvae, especially in their mobile period, are susceptible to pesticides.
Before starting the fight against scabies on cherries and other fruit, the following rules must be considered:
- water the surrounding land well;
- It is recommended that you first try non-toxic methods of control;
- spraying with a soap solution can be done no more than once every 7 days, it is better to use a mild liquid soap;
- to increase the effectiveness of drugs should be used alternately.
The treatment of garden trees from the false shields.
After scraping, the tree must be treated with insecticides. Experts recommend the following drugs:
- Actellik - an emulsion for controlling garden pests, it is not addictive, but it is dangerous for animals and people, t. It has a pungent smell;
- Aktara - a highly effective tool, dangerous for bees, is not used in residential premises;
- Bitoxibacillin is a drug with live bacteria, safe for humans and animals, there is no smell, but treatment must be done several times. Valid only at air temperatures above + 18˚С;
- The drug 30 is an environmentally friendly product that is used in spring until flowers appear on the trees.
Important! When using all of the above funds, be sure to wear protective clothing, a respirator and gloves so as not to get poisoned.
The scabbard is a pest that is difficult enough to destroy. For this reason, methods of combating scale insects must be chosen very carefully, since their carapace reliably protects not only offspring. It will not be superfluous to acquire a metal brush and a scraper, since the bark will need to be cleaned by hand.
Adult plants are difficult to clean from the parasite mechanically. Therefore, you must also use chemicals.
It is necessary to strictly observe the processing time, since most of the success depends on this. Do not forget that chemical compounds can harm not only insects. Negative effects can be exerted on vegetation and humans, which makes it necessary to use special equipment. It is best to get gloves, goggles and a respirator to protect the mucous membranes. It is also important to have a quality atomizer.
The main task of preparation is the purchase of the right, effective chemical. It is necessary to purchase only authorized drugs, since there are many fakes and cheap analogues that do not have any effect on parasites.
We apply specialized preparations to the soil
Garden and garden soil must be treated, even if no insects are seen there.
It is necessary to get rid of scabies by watering the soil with chemical agents:
- Confidor is used to spray vegetation or water. The drug can be used for a long period. The main thing is that poison accumulates in the deciduous part, which means that the fruits do not absorb it. A similar procedure allows you to process a home garden without harm and loss of crop;
- Actara best shows its effectiveness when applied to the soil part, but can also be used to irrigate vegetation. When fertilizing the soil, the protective properties are preserved for 2 months, for comparison, spraying allows you to protect only a few weeks.
How to deal with double-tails in a private house and garden?
Fighting with two-tails is quite simple: either with chemicals or harmless folk methods.
These insects love a humid environment, so if possible it is necessary to drain the space: do not spill water, repair pipes and taps. If this is not possible, it is possible to sprinkle boric acid powder in the habitats of the double-tail (wet dark corners, crevices, behind the baseboards).
Two-tailed - a nocturnal resident), so during the day I always catch them with a wet rag thrown as if by chance - it serves as a trap. After 2-3 hours, along with a rag, I throw the two-tailed bird into the yard (at the cottage in the forest, where you can’t get rid of moisture).
It is also possible to use various intexicides - in this case, you need to carefully read the instructions (crayons, sprays, gels), only if there are children in the house, I would not use them, but in the garden this is what you need.
Many people also recommend tincture of onion and garlic: chop a couple of cloves of garlic and the same amount of onions, add a liter of boiling water, leave for 2-3 hours and spray the floors and crevices with this infusion.
Try it) some method will definitely work! Start safe :)
Prevention of re-infection
Using preparations from scale insects on fruit and other trees, you need to carefully process them and prevent re-emergence.
Prevention can be used as an initial method for removing parasites:
- it must be remembered that sexually mature individuals are inactive, which means that it is necessary to temporarily stop planting new trees. Especially in close proximity to infected crops;
- buying seedlings from reliable sellers is also a kind of fight against insects. It must be remembered that most cases of infection occur due to the acquisition of infected seedlings;
- Autumn should be accompanied by a digging of the soil, and spring - by cleaning the remains of foliage and infected parts of trees and other vegetation.
These simple methods protect the site from the misfortunes of scale insects. Periodic inspections of the plant will not allow the parasites to multiply and will help preserve the crop. The fight against scale insects is not an easy task, however, comprehensive control measures have a noticeable effect and can achieve good results.
Coniferous false shields, how to quickly and effectively get rid of an insect read more in this article.
It is not easy to completely destroy the scale shield on the site, insects quickly spread and actively multiply. To achieve the effect, preventive measures are needed, an active fight should be started at the very first signs of infection.
