Viburnum leaf beetle
Beetle leaf beetles can completely destroy planted viburnum bushes, and the fight against these pests is very difficult. Many, most likely, had to experience it, so we will tell you about an effective method of dealing with leaf beetles.
In early spring, dark-gray larvae hatch with a black head. They settle on the underside of the sheet, and it is very difficult to shake them off, because they stick hard at it. These larvae are very voracious. In a matter of days, they can gnaw up most of the leaves. Then they burrow into the soil and after a while they crawl out with yellow-brown half-centimeter beetles. Now they settle on the upper side of the foliage and continue to assimilate them diligently. By the fall viburnum, struck by leaf beetles, is almost all bare. Such a plant is not ready for winter and can simply freeze.Females gnaw the bark two millimeters deep, they can even hook on wood. Up to 25 light yellow eggs are laid in the hole. After the female, the nest is sealed with bodily secretions, masking to the color of the bark. But masonry can be distinguished by their convex shape. Some of them organize nests in the petioles of large brushes. As a result, the harvest drops sharply. By autumn, beetles occur in the winter under a bush of viburnum.
There is one fairly simple way to protect Kalina from further adverse effects of leaf beetles. During the mass appearance of beetles in the middle of summer, they should be shaken off early in the morning, at the moments of their least activity, from foliage to plastic film. After they are removed in a bucket of water and pour away. Try to carry out this operation before the beginning of the period of procreation.
We also call the proven folk remedies for pests on Kalina. With the beginning of spring, when the branches of viburnum are not yet overgrown with young leaves, you can cut off the tops of the shoots, where eggs can be seen. Cut the pieces immediately need to burn. If everything is carefully checked and eliminated, then next year new bugs will not appear.
This pest looks like a caterpillar of a gray-blue or greenish-olive shade with yellow on the sides and covered with light hairs. Her head is dark brown. Caterpillars that hatch in spring devour the buds when leaves start to appear. They entangle them with cobwebs and knock them into lumps. By the middle of the summer, the pupillus begins pupation at the places of its feeding. In large quantities, this pest can almost completely embrace viburnum, which adversely affects the subsequent harvest.The struggle with the leafworm is reduced to a simple gathering of nests of caterpillars with their subsequent burning. Before budding Kalina should be treated with paste "Nitrafen". The 60% mixture comes out of a bucket of water with 250 grams of substance added to it. In the period from bud break to the appearance of buds, the shrub needs to be treated with 10% Karbofos solution.
Kalina and honeysuckle gall midgesThese pests prefer, in contrast to previous ones, to “feast” on the flowers of the plant. Gall midge larvae have a white color, and honeysuckle color is red. They overwinter in the upper layer of soil, wrapping themselves in cocoons of cobwebs. Adult gall midges are active at the first budding of the buds. Females lay eggs inside the buds. The larvae also develop there. As a result, the buds deform, increase in size, redden and swell. The corolla becomes thicker, the pistil and stamens are retarded in development, and the flowers do not open. Gallicus give only one offspring.
Measures to combat these pests are loosening the soil in early spring and late autumn. Before and after flowering, viburnum should be sprayed with a solution of Karbofos in a 10% ratio.
Honeysuckle Spiky SawflyThe larva of this pest has an olive body with two rows of white cross thorns. The back is painted in burgundy or mesh pattern. The sides of the sawfly larva are light gray, and the head is yellow. They winter in the upper soil layers, and pupate in the spring. Adults appear in the period of foliage blooming and can gnaw Kalina naked.
The struggle with sawflies begins in the autumn with a thorough digging of the earth. Next, you should enter drugs for viburnum: 10% solution of "Malophos" and wormwood decoction, which is sprayed with viburnum before and after flowering.
Black viburnum aphid
Adult aphid on Kalina lays its eggs on the bark near the kidneys. Future larvae also winter there. Having appeared on the light, they make their way to the leaves and suck out all the nutrients from them. As a result, the leaves begin to curl, and the apical shoots deform. At the beginning of summer, pests appear with wings that colonize new plants. In August-September, the cycle closes - black aphid females produce another offspring, which will overwinter.This pest is able to migrate, but lives exclusively on Kalina. Blackfly hordes with special efforts damage young bushes. Black Kalina aphid can migrate, but lives only on Kalina. With particular cruelty, it damages young bushes. During the growing season, viburnum in aphid develops several generations.
Novice gardeners often wonder how to get rid of aphids on Kalina. To overcome the black Kalina aphid, you need to cut and destroy the growth, which is common at the roots. There are pests and lay eggs before wintering. To destroy aphids, you can run beneficial insects that feed on it. These can be hover flies and gold-eyed larvae, ladybugs.
Before budding, treat shoots with Nitrafen paste at a concentration of 60%. Well help to get rid of aphids herbal preparations: infusion of potato tops, pepper tincture or solution of soap.
Chelkovaya mothThe larch moth is a tiny butterfly with a wingspan of not more than 10 mm. Her gray body is covered with shiny scales. Moth larvae in the size of no more than half an inch of orange-brown color. The caterpillar makes a cover for itself in the form of a case according to the size of a calf and winters there. In the spring, it feeds on viburnum leaves, in June it pupates and in July it becomes a butterfly, which lays a couple of eggs. In summer, caterpillars hatch from eggs.
In the fight against deciduous moths moth will help the next spring treatment from pests - spraying viburnum in the period of regrowth of young shoots. In the summer, Fufanon, Aktellik, Komandor, Iskra and Inta-vir should be used.
The main diseases of viburnum treatment methods
Various diseases that plaque can affect can overcome it year after year, and their number is striking. The difficulty is that finding out the cause of the disease, even with careful diagnosis, is very difficult. It is possible to make only a single general conclusion that a plant has undergone a virus attack, when spots or strips appear on its leaves that differ from the natural coloring.
Viburnum leaves are rarely affected by this disease. This type of fungus infects viburnum only in the summer, when it is rainy and cool. Only at the time when conditions for pore ripening arise. To remove unpleasant disease, you should enter the following preparations for viburnum:"Topaz", "Strobe" or copper-soap solution. Well in this case also wood ash, which is cleared of particles of coal, helps. Three kilograms of ash need to fill a bucket of hot water and insist two days. Treat Kalina with powdery mildew twice a month.
Leaf spottingOn the leaves of viburnum are formed gray spots of various shapes with a border of brown or purple. On the underside of the leaf, the spots are olive gray. By September, dark dotted fruiting bodies of the fungus begin to form on the dead tissue. Then the spots crack, dry, and the middle of them falls out.
Fighting spotting is quite simple. It is necessary to remove all affected leaves from the bush. During the budding period, it is necessary to spray Kalina with Bordeaux mixture or copper oxychloride.
Gray and fruit rot
Gray rot affects viburnum during periods of cold and rainy weather. Especially in the summer. Leaves first acquire large brown spots, spreading over the surface. They quickly grow in size, dry out and crack. Spores from infected leaves fall on healthy ones. Berries affected by gray mold turn brown and dry. The fungus eats them through. On the surface you can see a smoky gray spore. To get rid of the disease, you need to collect all the fallen leaves in the fall. If viburnum is strongly affected by this disease, then it should be sprayed with the drug "Vectra" during the vegetative period.Fruit rot affects young shoots of a plant. They dry together with flowers, leaves and berries. With the onset of summer, the berries that struck the disease are covered with dense pads, then mummified and blackened.
You can cope with fruit rot by removing mummified berries with the onset of autumn. You also need to spray the bushes with copper oxychloride before the flowering period of viburnum and after it.
Yellowing and mosaic of leaves
Mosaic diseases are a group of viral diseases characterized by a motley pattern of the affected organs with alternating spots of various sizes and shapes. The affected areas are painted in green or white color of varying intensity. The lamina is deformed, and the plant begins to lag in growth. Mosaic infestation can occur through seeds, the juice of diseased plants when picking up seedlings, through pasynkovanie, in contact with infected plants with healthy ones. Mechanical carriers of the virus - aphid, bedbugs, mites, soil nematodes. Viruses penetrate into plants through damaged tissue, are stored in the soil, plant debris and seeds.To date, unknown methods of dealing with this disease, which would cope with it forever. The only thing that was achieved was to find preventive means and bring out varieties resistant to the mosaic of leaves. If the level of infection has not reached a critical point, then you can cut the diseased areas. If viburnum befell irreversible consequences, then the shrub need to dig and burn.
Signs of infection are primarily noticeable on young, growing shoots. They begin to see light areas along the veins, yellow rings and spots in the form of stars. Then the spots turn white, and with their further merging the leaf begins to turn yellow. Mosaic disease progresses faster at a temperature of 30 degrees, when the plant is heavily thickened.
Resistance to the disease decreases with sharp temperature differences, higher than 30 degrees, temperature and very dense distribution of plants. Here you need to comply with a certain thermal regime. Often the disease is transmitted by insect pests, so you need to carefully monitor their appearance and time to destroy. Having discovered the disease, it is necessary to take preventive measures: isolate viburnum and disinfect the inventory. If the plant dies, it must be dug up and destroyed along with the surrounding soil. Accurately determine the specific disease of Viburnum is very difficult.

Viburnum pests - Diseases and pests
Kalina is a very popular garden culture in our area. This shrub won the love of gardeners with its beautiful decorative appearance and extremely healthy and tasty fruits that are rich in vitamins and other healthy substances. At the same time care for viburnum is quite simple. However, like other garden plants, it is susceptible to the attacks of various pests that must be dealt with in a timely manner.
Viburnum pests are quite common and one of the most common pests that infect viburnum bushes is black aphids. It is a dark brown or brown insect. Aphid lays its larvae on the leaves of viburnum, as a result of which the leaves curl and dry, because the larvae drink from them all the juice. You can fight this pest with the help of special preparations, as well as infusions of pepper, celandine or solution of laundry soap. Ladybugs also help in the fight against aphids.
Another common pest of viburnum is a small beetle - the snowball leaf beetle. Their size is only 5-7 mm, but they multiply quickly enough and are able to eat all the leaves of the bush, leaving only large veins. These pests of viburnum are quite dangerous, since the plant damaged by them will not bloom next year. You can fight them by spraying with karbofos, if this is done before flowering, with pepper tincture or pharmaceutical chamomile, if spraying is done at a later period.
There are other pests of viburnum, which are not so common, but also occur quite often.
The most common pests
Viburnum has many admirers not only among humans, but also among insects. However, the preferences of the latter for her disastrous. The following are the pests that can cause the greatest harm to Kalina, as well as how to get rid of them and save the plant.
Black aphid on Kalina, how to fight
These small bugs are easy to see: they are brown, almost black, color (less often raspberry-brown) and accumulate in large quantities on the stems of the plant. They lay eggs in the bark of viburnum, as well as on the branches. In the spring the larvae hatch, begin to suck out the juices and eat the young leaves of the plant. They eventually dry and wrap, and shoots change shape.
Generally aphid attacks three times a year, starting in May. In this month, you must begin to treat the plant with insecticides. Then the aphid larvae grow and turn into flying insects that are able to fly to neighboring plants. In August, the aphid begins laying eggs, which can successfully winter, despite the cold weather.
Black Aphid on Kalina
The measures for combating Kalinovo flesy include the destruction of basal shoots, the greatest number of eggs are laid there. What can be treated with viburnum Kalina? The plant should be sprayed with chemicals:
- Akarin or Agravertin EC,
Also, it will not be superfluous to treat the plant with a solution of household or tar soap.
Important! The first treatment is best done before the bud break, this will help reduce the number of overwintered eggs.
What if the use of chemicals in this place is impossible? Help folk remedies. For spraying, you can use decoctions prepared from other plants. For this, potato tops (1.2 kg of green per 10 liters of water), pepper infusion (1 kg of paprika per 10 liters), celandine (3-4 kg of fresh celandine per 10 liters) are suitable.
It will also be useful to purchase or lure beneficial insects that destroy aphids on Kalina. This is a ladybird, a hoverfly fly or a goldmilk larva. Insects will eat exactly pests, and viburnum is not touched.
Green Swan Moth
The caterpillar has a yellow-green color with a dark red stripe along the body, the same points and spots. Prefers to eat only flowers, gnaw flower ovaries. Especially active from May to July. Over the summer, two generations of butterflies may appear. The most common peppered moth is found on the ornamental shrub Buldenezh. In addition to viburnum can harm and other garden shrubs, such as lilac and buckthorn.
On a note! Fight against the pest should be carried out twice: in the spring, before the flowering of viburnum and after its completion. For processing will suit 10% Karbofos.
Black Kalina aphid. Description and signs of damage
Small bugs of dark color: brown, almost black shade. Eggs hiding in the bark, on the branches of the bush. The larvae hatched in spring begin to colonize the young, just blooming leaves and feed on their juice. As a result, the leaves begin to dry and coagulate, and the tip of the shoot changes its shape. At the same time, the growth of the bush slows down significantly.
It is noticed that the attack of aphids occurs three times a year. The season begins in May. During this period, it is recommended to treat viburnum with any insecticides of a wide range of action.
In summer, aphids become adult flying insects that migrate in search of new viburnum bushes. At the end of the summer, eggs begin to be laid, of which after a successful wintering, a new generation of viburnum aphids appears.
Methods of dealing with black Kalina aphids
Cutting grass near viburnum bushes can be considered a natural way of getting rid of the pest: it is here that females often hide eggs and also use insects useful for the summer cottage for whom aphids are a natural source of food (hover flies, ladybugs).
Калинная тля, очень часто поражает молодые, только развивающиеся ветки в весенний период. Поможет уменьшить численность вредителя, не используя вредных химические средства - дождевание. Дождевание проводят в вечернее время охватывая всю крону растения. Рекомендуется также, проводить борьбу с муравьями, которые распространяют тлю.
In the fight against pests viburnum will help natural products on a plant-based:
These methods are especially important during flowering and fruiting. On the eve of flowering viburnum, it should be sprayed with any infusion that has a strong smell. For example from, wormwood, needles, various odorous weeds, dandelions, etc. The procedure is carried out before bud break and after, or once a week - until complete destruction of the pest.
- infusion of potato tops (600-700 grams. dry tops of 10 liters of water)
- infusion of celandine (2-3 kg of fresh or 1 kg of dried plants per 10 liters of water)
- Infusion of hot pepper (1 kg of pepper pour 10 liters of water).
- Also, a noticeable result is obtained by spraying the bushes with a solution of household soap (200 g. Of soap, grate and dilute in 10 liters of water).
Preparations with chemical composition:
- Before the buds bloom, it is recommended to treat the bush with 60% infusion of nitraphine, at the rate of 200 g. drug per 10 liters of water.
- In early spring - during the growing season, it is recommended to treat the bush with a solution of karbofos or Fufanon (covering the face with a wet gauze bandage). However, spraying should be stopped one month before harvest.
- As mentioned above, ants are the main culprit in the spread of aphids, so without dealing with them it will be quite difficult to cope with aphids. For the destruction of ants use "Fufanon", "Aktara", "Confidor", "Rogor", etc.
Methods of dealing with Kalin leaf beetles
A thorough examination of the tops of viburnum in the autumn is necessary in order to detect the pests in time and destroy them. A similar inspection should be carried out in early spring. With the advent of the first leaves, all the larvae will be exactly on them. During this period, you need to have time to pinch off the leaves and destroy. After a couple of days, this procedure must be repeated.
In order to prevent active breeding of leaf-eating pests of viburnum, it is recommended to treat viburnum bushes with chemical preparations even before bud break:
- 0.3% solution of Malathion,
- 0.1% solution of Fufanon or 0.15% solution of "Rogora".
- If the amount of the pest has begun to increase rapidly, the treatment of plants with a 0.08% Aktara or Eleksary solution will help.
- You can also conduct a double spraying (with an interval of 7-10 days) with the preparations "FAS" or "Intavir" (at the rate of 1 tablet per 10 liters of water).
Most of the females lay eggs on the tops of young shoots, making deep tunnels, then lay eggs in them. Therefore, by September, these shoots are already dry. If a bush is young and not too tall and large, then the best way to get rid of egg laying is to remove and then burn all dried shoots.
Such a “cleansing” is necessary both in autumn and in spring, until the emergence of new larvae. If you destroy the eggs, there will be no larvae or adults.
Viburnum moth Description
The larvae of the viburnum moth are caterpillars of a grayish or greenish-olive color, which immediately after the spring appear, begin to actively eat the buds and young leaves of the viburnum.
At the same time they entangle the leaves with cobwebs, knocking them into a ball. In the middle of summer, pupation of caterpillars occurs.
If conditions are favorable, they are able to gnaw large areas of foliage in a short time, which has the most negative effect on yield.
How to deal with viburnum moth
- Mechanical collection of nests together with pests and their subsequent burning will help to get rid of the caterpillars.
- Also, before blooming buds, it is recommended to treat viburnum bush with nitrafen paste, and after blooming with buds, karbofos.
- During the period of insect mass appearance, it is necessary to apply 0.05% inta-vir or decis (dissolve 1 tablet in 10 l of water). After two weeks, repeat the procedure.
Methods of dealing with thyroid prickly sawfly
- An effective preventive measure to prevent the occurrence of these pests is a deep digging of the soil in October-November, in order to get rid of the sawfly larvae hibernating in it.
- Also a good result is obtained by spraying karbofos, which is carried out both before and after flowering.
- If we talk about natural means of combating this insect pest, then we can use the treatment of viburnum with a mixture of tobacco, onion and garlic, or spraying a decoction of wormwood.
Kalinnaya Gallitsa Description
A feature of this pest is the fact that it damages only the flowers of viburnum. He spends wintering, hiding in cocoons in the upper layers of the soil. In the period when the buds appear on the surface, adult insects are chosen, which begin to lay eggs inside the buds. The hatched larvae feed on the pulp from the inside, thereby disfiguring the shape of the bud.
Naturally, in such conditions, the flower does not bloom and the yield of viburnum is significantly reduced.
Measures to combat Kalina gall midge
Digging in the fall in order to get rid of the larvae hibernating in it. Processing karbofosom before and immediately after flowering. Green Blade Moth Description Causes damage to Kalina, as well as many other common garden crops.
Painted in bright yellow-green color, with a reddish-brown stripe on the back and spots of the same shade. It has two pairs of abdominal legs. It damages only flowers, gnawing flower ovaries. Control measures Before and after flowering, viburnum bushes should be sprayed with 10% karbofos (90 g per 10 liters of water).
Features of growing different varieties of viburnum
On the Crimean Southern Coast, viburnum blooms very early - starting from mid-December, but the peak of pink and snow-white bloom comes in May. There are many varieties of viburnum and each has its own particular cultivation:
1. Kalina "Avabuki". This stately variety of viburnum was bred in Japan, as well as in South Korea. Avabuki refers to winter-hardy varieties of viburnum. At high temperatures only foliage is damaged. On the southern shores of the Crimea, in very cold winters, the tips of the young shoots may freeze slightly.
2. Barwood. Propagated by cuttings, this type of viburnum needs shading and drained soil,
3. Biodian Viburnum. Cherenkov reproduction. Kalina prefers a lot of sun, and also needs loosened and well-hydrated soil,
4. Gordovina. Europe, North Africa and South-West Asia are considered to be home to this variety. This variety has a high frost resistance, makes it well temperature down to -35C. The plant perfectly adapts to various conditions, as well as drought, and high humidity:
5. David. This variety of viburnum also propagated by cuttings. The plant prefers more shady places with moist soil with good fertility,
6. Kalina fragrant. It has a weak frost resistance, tolerates only up to -5C. Propagated by cuttings. Planted need to putrid, sour, fertile soil,
7. Kalina Carls. This variety is widely used in Europe as a decoration for the garden, very cold-resistant (-30C). The plant is not fastidious to light, it is necessary to plant it on the drained soil,
8. Cariconus viburnum. The variety is bred in China, where it enjoys high popularity. The plant does not withstand low temperatures (down to -5 ° C), it is necessary to plant in acidic soil.
In order to viburnum planting and care were correct in the article listed photo.
Planting viburnum and care with photos
The plant needs well-lit and semi-shady areas. Kalina is not a fastidious plant, if you plant a bush of viburnum in a well-moistened soil, the plant will surely delight you with excellent flowering and abundant harvest. Viburnum can be planted with the onset of spring and autumn. Optimally, landing is considered at the beginning of April.
In order to plant a plant, first of all you need to dig a sufficiently deep hole, approximately up to 50 cm. Next, a nutrient mixture is poured into the hole, which will feed the plant for 3 years. The mixture consists of humus, leaf and garden soil, peat and complex mineral fertilizers, which include potassium, phosphorus and nitrogen.
Young seedlings of viburnum, must be placed in a hole in the looped mixture, with it being important that the root neck is 5 cm deep. This stimulates the growth of new roots, which will strengthen the viburnum in the soil and help it to quickly adapt.
After that, the seedling should be covered with earth and watered with warm water. In order to protect the root system, it is necessary to pour a mulch mixture around the seedling.
The larvae of this pest are caterpillars of gray or green color, which have a yellow shade on each side. The entire torso of the caterpillars is covered with light hairs. Activated in the spring. They actively eat buds and young leaves of the plant. In addition, they are wrapping the leaves with cobwebs and knocking them into a ball.
The caterpillars of the leafworm are capable of real sabotage: in a short period of time they can eat huge amounts of leaves and inflorescences, which negatively affects the yield. To avoid such that all the leaves of viburnum ate the caterpillars, you need to start fighting with them in time.
Note! To destroy the viburnum leafworm, you need to collect and burn all the tracked nests. Then spray the plants with 60% Nitrofen paste (250 g per bucket of water). This should be done before the leaves bloom. Then it is necessary to treat Kalina 10% Karbofos.
Folk methods of struggle
Many gardeners prefer not to use chemicals for pest control. And there are a lot of folk methods: besides decoction of the garden plants listed above, spraying with a solution of soap is recommended. Such a solution is prepared using household soap or tar. You just need to dissolve the soap in water, about 100 grams per 1 liter of water, preferably warm.
Note: it is much more convenient and faster to dissolve soap chips.
This method is absolutely safe for humans. For greater efficiency, it is recommended to add to the solution:
The following are ways to prepare each solution.
The effect of the use of this tool will be noticeable by the end of the day. To prepare, you must mix the soap with water (1/4 or 1/2 part of a bar of soap is enough per bucket), then add soda at the rate of 1 tablespoon per liter of water. A bucket will take about 10 tablespoons of soda. Mix thoroughly and spray the plant properly.
Preparation of soda-soap solution for spraying
Wood ash strongly irritates the skin of insects, so it is great for pest control. A soap remedy will help fix the ash solution on the leaves.
First you need to sift 300 grams of wood ash, add to a bucket filled with 10 liters of water and put on fire. Boil for half an hour. Then it is necessary to cool a little and add 40 grams of soap.
Tip! To do this in advance is not worth it, it is better to prepare just before use.
To prepare, mix 200 grams of dry tobacco leaves with three pods of bitter pepper and pour all over with a bucket of water. Insist day. Then add 100 grams of soap, 3 tablespoons of wood ash (can be replaced with cinnamon) and mix. Such a solution is able to quickly remove pests.
To prepare the solution, you can use potato or tomato tops. It is necessary to grind 3 kg of fresh herbs, pour 10 liters of water and insist at least 6 hours. Then put on the stove, bring to a boil and cook for half an hour. After that, cool, add 50 grams of soap and use.
The use of soap solution for spraying viburnum is safe for humans and accessible to everyone. However, it is not always possible to cope with harmful insects only with the help of folk remedies. Store preparations are much more effective, but they also fail to kill all pests the first time. For maximum efficiency, it is worth using folk remedies in combination with shop ones.
Important: because of the need for chemical processing, it is not necessary to plant viburnum next to the beds; it can be dangerous to eat such a crop.
For the prevention of diseases of viburnum and to detect early signs of the appearance of pests need to regularly inspect the plant. If the leaves began to turn black, dry or rot, holes appeared on them, you need to look for the cause and fight it.
For prevention and treatment, it will not be superfluous to process the bushes with onion, garlic or tobacco infusion, as well as soapy water (any of the previously described) throughout the season. As a preventive measure for diseases of viburnum, as well as for the control of pests, the use of insecticidal plants is perfect. It can be horse sorrel, dandelion, bitter wormwood.
Fully protect Kalina will not work, pests can attack again, but the timely detection and destruction of harmful insects will prevent them from laying eggs.

1. Viburnum leaf beetle (Galerucella viburni Payk).
A light-brown beetle up to 6 mm long in August lays eggs (up to 700 pieces!) Into recesses made on young shoots. Shoots dry out, but they successfully overwinter clutches. In early May, the larvae emerge from the eggs and immediately begin to feed intensively on young leaves and shoots. In early June, they go to the soil for pupation. In July, beetles appear, leaving huge holes in the leaves. With a larger number of leaf beetles do not stop berries and shoots.
Measures to combat viburnum leaf beetle
- Autumn and spring pruning of dried and damaged shoots, removal of leaves with leaf beetle larvae.
- Spring processing before leafing and in August during the release of leaf beetles by one of the preparations according to the instructions: "Fufanon", "Malathion", "Actellic", "Aktara". Double processing"Intavir"with an interval of 7-10 days.
2. Viburnum aphid (Aphis viburni Scop.)
Black viburnum aphid leaflet is a small insect up to 7 mm long. Larvae appear from hibernating eggs when the leaves are blooming. They actively reproduce, feeding on the sap of the plant. The leaves curl, deform and dry.
Measures to combat viburnum aphids
The first treatment - before bud break - will help to significantly reduce the number of overwintered eggs, so it is better not to postpone it. Alternate the drugs: “Arrivo”, “Fury”, “Fufan” (aka “Fufanon”) and “Karbaphos”. Biological preparations can also be used: “Fitoverm”, “Akarin” (“Agravertin KE”, “Aversectin”), Iskra ”,“ Intavir. ”They quickly decompose and do not cause addiction in aphids.

3. Other pests of viburnum
The Kalina moth and a comma-shaped shield strongly affect Kalina. To combat them, in May the plant is treated with Karbofos (90 g / 10 l of water), and in August they are sprayed "Fufanon " or "Spark.
In cold rainy weather, young shoots are affected by various fungal diseases: gray rot, phyllostiktosa spotting, fruit rot, powdery mildew.
In wet weather, spots appear on the leaves, spore spread of fungi. Plant growth slows down, tissue transpiration worsens, young shoots dry out, badly damaged leaves fall prematurely. The plant is poorly prepared for winter, has a "miserable" appearance, yields are reduced. Infection persists in plant debris.
How to deal with diseases of viburnum
For the prevention of diseases such as spotting and powdery mildew, during the whole season Kalina should be treated with tobacco, garlic or onion infusion. Do not forget to remove plant residues, thin out the bushes, carry out sanitary pruning.
In case of severe damage by rot, before the leaves bloom and after flowering, the bushes are treated with Bordeaux mixture or preparations "Hom", "Abiga-Peak".
Caring for a plant involves several steps:
1. Watering viburnum. A young sapling planted should be watered with the onset of the evening, the soil should be soaked about 40 cm. The adult plant should be watered during the growing season and during the harvest period.
2. Top dressing. With the onset of spring, the soil around the plant must be fertilized with 2 tablespoons of urea. Before viburnum begins to bloom, the soil should be fertilized with 2 spoons of potassium sulphide or wood ash. In the summer, viburnum needs to be fed with complex mineral fertilizers, it takes 60 g. After 2 years, with the onset of autumn, it is necessary to fertilize viburnum with rotted manure and combined phosphorus-potassium fertilizers. When drought, to achieve the effect, the fertilizer must be diluted with water.
3. Crown formation and trimming. For the year, the branches of viburnum are able to grow by more than 40 cm. It is necessary to prune with the onset of spring, it is necessary to form a crown, remove unnecessary or painful branches. For fully mature, not young plants, it is recommended to perform a rejuvenating pruning, but this procedure must be done when the shrub has reached the age of 6 years. To do this, outdated shoots must be cut to the root. But you need to leave about 15 branches. If the bush is very weak, gives little fruit, it must be cut at the root to 20 cm, which stimulates it to active growth.
Pests and diseases of viburnum, methods of treatment
The main pests of viburnum include:
1. Viburnum leaf beetle
Beetle, light brown color, size up to 6 mm. С наступлением августа начинает в углублениях побегов растения откладывать яйца, в шокирующих количествам – до 700шт. В зимний период, молодые побеги высыхают, но отложенные яйца спокойно перезимовывают. В мае яйца созревают и из них вылупляются личинки, и сразу же приступают к уничтожению молодых побегов и листьев. В июне, личинки зарываются в почву для окукливания.Already with the onset of July beetles appear that eat the leaves.
How to deal with viburnum leaf beetle?
- It is necessary to cut off young shoots in autumn and spring, and also immediately remove the leaves on which there are larvae,
- In the spring, even before the leaves bloom, the bush must be necessarily processed: Fafanon, Karbofos, Aktelikom, Aktar. And also you need to take Intavir twice with an interval of up to 10 days.
2. Kalina aphid

It is necessary to get rid of this, since it is fraught with a slowdown in the growth of viburnum, deterioration of tissue transpiration, young shoots inevitably begin to dry out. Also, the result of high humidity is abundant premature abscission of foliage. As a result, the plant will be poorly prepared for the winter period, there is a high likelihood of the plant drying out, or a lower yield with the onset of summer, as the infection continues to develop in plant debris.
