Violet is often attacked by pests. In most cases, the emergence and spread of parasites contributes to improper agricultural technology. How to recognize this or that pest and get rid of it? Is it possible to save an infected plant? What drugs are considered the most effective for the treatment of senpolia?
Thrips
Begin the list of pests of violets with thrips photos. The flower is attacked by both adults and larvae, feeding on its juice. The body length of the parasite does not exceed 1.5 mm, the back is colored black and brown, the larvae are yellow.
Adult insects are able to fly over short distances, so if measures to destroy them are not taken in time, the entire flower garden will soon be infected. Female parasites lay eggs directly in the body of the plant - the flesh of the leaf plate. Moreover, in one clutch alone there can be about a thousand eggs. After a few weeks, larvae emerge from them, which in about a month turn into adults.
With the advent of thrips, the leaves of plants change their color - they clearly form distinct whitish stripes and dots. If young eggs have already come out of the eggs, then in this case the flowers will begin to wither, and the plant itself will rapidly wither. In this case, a colony of violet pests can be found on the lower part of the leaf plate - this is where they parasitize and multiply.
Thripses infect plants regardless of temperature conditions and time of year, giving one or two generations per quarter. In most cases, infection occurs from garden flowers (chamomile, aster, chrysanthemum), which enter the house during the flowering period.
In order to get rid of thrips, you must first cut off all the flowers and buds, and then treat the infected violet with Confidor. Soil is shed with Aktara. After 10 days, the treatment is repeated and over the next month they continue to remove newly formed buds. In the future, it is very important to maintain proper agricultural technology.
Mealybug
A small insect whose body is covered with a whitish fluff that lives in the axils of the leaves, as well as in young peduncles. Mealybug sucks nutrient juices from plants and simultaneously releases saliva, which, in turn, infects the flower and interferes with the normal metabolism.
In the place of bites, leaves and flowers are deformed. Red-brown spots appear on them. When transplanting an infected specimen from the substrate, you can feel a specific fungal odor. These pests of violets are very small, but since their body is covered with a white fluff, you can quite notice them with a detailed examination of the plant.
In the Saintpaulia, the mealybug is moving from garden plants brought home. If there are too many parasites, the attacked flower loses its decorative effect in a short time. In doing so, he becomes more susceptible to many diseases.
Pests of violets are destroyed with the help of the drug "Aktara", "Fitoverm", "Mospilan" or "Actellik". After 10 days, it is advisable to repeat the treatment. According to reviews, if it’s not the first time you have been fighting the worms and are already reusing the “Aktara” remedy, then parasites have more likely to develop immunity to it. Florists recommend each time to use different systemic insecticides, which will differ in their composition.
In this case, the use of an insecticide alone is not enough. The infected plant must be transplanted into a new substrate. The pot in which the infection occurred is also desirable to throw away.
Root worm
The rootworm is a “close relative” of the aforementioned parasite. Their names are similar, but different taste preferences. This is a small insect that is a dangerous pest of uzambar violet. If the mealybug attacks mainly the green part of the plant, then the root, as the name implies, leads an underground lifestyle, infecting the rhizome of the flower.
The root worm is dangerous because it is often possible to detect it very late. By this time, the plants are damaged quite severely and the main symptoms are obvious: development stops, leaves become faded, flowers appear, but in small quantities. Over time, the flower loses turgor, turns yellow. This suggests that a significant part of the root is destroyed. And since the worm parasitizes underground, the grower simply does not see it. Below is an enlarged photo of pests of violets.
The fight against them is carried out using one of the following drugs: "Regent", "Aktara", "Dantop", "Mospilan". The selected agent is used to spill the infected substrate three times with an interval of 10 days. At the same time, the Aktara remedy in the concentration recommended by the manufacturer is often ineffective. If after the first treatment a positive result did not follow, it is necessary to choose another systemic insecticide. And remember that in the fight against mealybug contact-intestinal drugs do not help.
Ticks
Ticks continue the list of pests of violets (with photos). Their treatment for infection with this parasite will be long, since the latter are so small that it is very difficult to detect them at the initial stages. They settle and breed, as a rule, in conditions of high humidity. On violets, cyclamen, red spider web and spider mites are most often found. They live mainly in plant outlets.
When ticks appear on the back of the leaves, indented traces appear, the plates begin to deform, become covered with red or brownish spots. These spots after a while become entangled in a thin web. The plant becomes untidy, as if covered with a layer of dust. Gradually infected violet lags in growth, new buds do not form, and already released ones do not open, pollen spills out from anthers. With a decrease in air humidity, the leaves begin to curl, dry out, the lower leaves are especially damaged.
Pest control of violets is carried out in several stages. First of all, it is necessary to thoroughly, but very carefully rinse infected specimens under running water (do not use cold!). Thanks to this event, it will be possible to remove a significant part of the parasites. Treatment is with acaricides. Sick plants are treated two to three times at weekly intervals. In parallel, the infected substrate is shed with Fitoverm or Actellik preparations. If there are too many pests, it is better to use Neoron with reprocessing after 10 days. In the future, violets should be placed away from each other and periodically arrange water procedures for them, especially in hot and dry weather.
Nematodes
Another pest of house violets that damages the roots of plants. Nematodes are small, colorless worms whose body length is about 1.2-1.5 mm. In females, the body is pear-shaped, in males - pear-shaped. Parasites breed very quickly, in one clutch there can be 300-500 eggs. Small larvae in a short time move to neighboring plants, quickly infecting the entire flower garden.
With the advent of nematodes, bloats are formed on the roots of violets - galls, which can have different sizes. In this case, the parasites themselves can be found inside these swellings. There they multiply and parasitize. As a result of its vital activity, the pest sucks nutritious juices from the plant and simultaneously injects toxic substances.
Symptoms of infection do not appear immediately. In order not to lose time and prevent the death of the plant, its roots must be carefully examined at each transplant. With severe damage to the root system, the aerial part of the violet also suffers: the growth point begins to dry out, new leaves appear in an altered form. Plant growth is slowed down, it looks weak and does not bloom, the green part begins to turn yellow. Gradually, the violet withers, its stem is deformed, the plant dies.
Unfortunately, in most cases, the flower cannot be saved. The infected specimen is discarded with the pot. If there is an urgent need to preserve the violet, treatment from pests can be carried out in the following way: remove from the substrate, cut off all damaged roots, treat the flower with a means to strengthen immunity and transplant into a new ground. The second way: choose a healthy leaf and try to root it.
It should be noted that it is much easier to prevent the appearance of nematodes than after trying to save an infected flower. To do this, it is enough to use clean soil when transplanting violets. You can not take the land either from a flower bed, or from a greenhouse, or from any other site where something grows or grew.
Aphids
Aphids are pests of violets (in the photo you can see how they look), which can be both with wings and without them. The length of their body does not exceed two millimeters, while it is so soft that the insect can easily be crushed by fingers.
Reproduction of aphids, and, accordingly, infection of plants, occurs very quickly: about 15 larvae leave eggs every 15 days. Small green pests settle on the back of leaf blades. With serious infection, a whitish, sticky pad appears on this part of the leaves.
You can recognize the infection of violet aphids by the appearance of buds and flowers. Petals begin to change their shape, flowers wither, buds do not develop. The leaves of the plant also begin to curl. Where previously there was a sticky pad, a soot fungus grows.
How to handle violets from pests? It is possible to cure an infected specimen with the help of special preparations: Fitoverm, Actellik, Mospilan, Intavir, Neoron. But before carrying out the treatment, the plant is carefully washed under running water, removing parasites from it. The rest are destroyed using the selected insecticide. After a week, the treatment is repeated.
Scaffold and false scaffold
Very dangerous pests of violets, the treatment of which is carried out comprehensively. The presence of sticky drops on the leaves of the Saintpaulia may indicate infection with scabies or false shields. In this case, the parasites themselves will be immediately detected if a more detailed inspection is carried out. These pests breed very quickly, and therefore it will be necessary to process all copies of your flower collection.
Most often, the parasite settles on the leaves, petioles and rosettes of plants. The body length of an adult is about 7 mm; on top it is covered with a kind of carapace or shield. At the same time, the shells are convex in the false scutes, and almost flat in the scutes.
After biting pests, small yellowish spots appear on the leaves. Over time, the leaf completely turns yellow, curls and falls off. With a serious infection, the violet begins to fade, discards all leaves and dies.
For the fight against scale insects and pseudo-scabs, “Aktara”, “Actellik”, “Agravertin” preparations are used. But before spraying, the flower must be washed under running water, then with their hands or tweezers they remove the detected pests of violets. In the future, the senpolies are located farther from each other, change the frequency of irrigation and adjust the light.
Sciarides
Mushroom mosquitoes, midges are pests of violets (senpolia) that destroy the root of the plant. At the same time, it is not adult individuals that parasitize the flowers, but their larvae, which, due to their size and body structure, can easily penetrate into the substrate.
Scyarides penetrate into houses simply from the street, sometimes their larvae are carried with soil. These parasites prefer high humidity and settle where there is a lot of decomposing organic matter - in such conditions they multiply very quickly, and as a result of their vital activity, the root of the plant begins to decay. Subsequently, the pest moves to the lower leaves. With a damaged root system, violet does not have the ability to restore strength, and therefore there is a risk of developing fungal diseases.
Pests of violets are destroyed with the help of the drug "Karbofos" or spill the soil with any other systemic insecticide. Very good results in the fight against larvae of scyarids shows "Regent". As a rule, 10 days after the first treatment, a second is carried out. In the future, it is necessary to pay special attention to agricultural technology. If it is violated, scyarids will certainly return.
Whitefly
Whiteflies are herbivorous insects that often settle on indoor violets. A photo of the pest can be viewed below. Their body length is about 3 mm. Insects feed on plant sap, both adults and larvae.
Whiteflies hide on the back of the leaf plate, where they parasitize, leaving behind a sticky coating. This pad becomes the ideal soil for the development of soot fungus. In addition, the parasite larvae attach to both foliage and flower stems, parasitizing in this place for a long time.
The infected plant begins to weaken, lags in growth, loses its decorative effect. Leaflets fade, buds do not open. With weakened immunity, violet loses its ability to resist the causative agents of bacterial, viral and fungal diseases.
In order to get rid of whiteflies, you can use the biological product "Actofit." This bioinsecticide is often used in floriculture against a wide range of pests. Usually spend 2-3 treatments with 10-day breaks. Also very good results in the fight against whitefly show "Aversectin C" and "Avertin-N". They are especially effective for mass infection of a flower with larvae. When this parasite appears, “Akarin”, “Fitoverm” and “Actofit” are often used.
Nailtails
Representatives of the Hypogastruridae and Entomobryidae families are often found in pots with Saintpaulias. As a rule, their sizes are insignificant - from 0.2 to 0.8 mm. These pests of Uzambara violet prefer places with high humidity, respectively, start where plants are watered too often. Dampness also contributes to the reproduction of parasites.
With a small number of these pests, violets are not able to cause serious damage to the plant. However, with a mass congestion, they begin to eat young roots of the indoor senpolia, as a result of which the infected specimens weaken, wither and may die.
In the fight against fools, it is necessary, first of all, to correct the watering of plants and to remove fallen leaves, since parasites often prefer to hide under them. Having reduced the frequency of watering, pay attention to the composition of the soil: with an excess of organic matter, increased reproduction of fungi and mold occurs. In most cases, these measures are enough to make the nails and podura completely disappear.
If there are too many parasites, then in this case it is recommended to transplant the violet into a new clean substrate. In emergency cases, the soil is treated with a Pyrethrum solution or systemic insecticides, for example, Aktaru or Mospilan, are used.
You can also use Bazudin. Granules of the drug are scattered on the surface of the soil with a thin layer. This is quite enough to destroy all the parasites that live in the soil. A similar action is provided by "Initiative". In order for the insecticide to work, it is mixed with the ground. The tool begins to work immediately - after a couple of hours, all the podura and footstails will be destroyed.
Woodlice
Woodlice complete the list of pests of violets with photos. Their treatment when infected with these parasites must be comprehensive. Mokrits is attracted by high humidity, and if the substrate in the pot is constantly waterlogged, then tiny crustaceans can be found in it over time.
Externally, wood lice are very similar to tiny armadillos. Settling in loose moist soil, they begin to multiply rapidly. Larvae and adults eat mainly the roots of violets, but sometimes the leaves of plants also suffer.
At the same time, young woodlice are considered the most dangerous for the senpolia. To combat them, acaricides are usually used. In this case, the treatment should be very thorough: in parallel, plants are sprayed and the soil is shed. As a rule, after 10 days the treatment is repeated.
Blooming violets can become a real decoration for your home. However, they will give you positive emotions only if you are able to provide them with proper care. Having studied this list of pests of violets and photographs, it will be much easier for you to recognize the infection in time and take the right steps to fix the problem. , , .
