Viburnum pests: tips for controlling diseases and pests. Proper care and cultivation of viburnum in the garden (115 photos)


Black aphid

As soon as the first buds on the viburnum bloom, the black (viburnum) aphid occupies the young shoots. Deprived of vital juices, young leaves become deformed and curl. Dark spots of various shapes appear on them, which leads to complete drying and death of young branches. In one season, several generations of aphids appear, and the first is equipped with wings - it has the ability to move from bush to bush, capturing all plants, not just viburnum.

The last generation overwinters at the base of the bush and, at the first signs of the beginning of spring, rushes along the trunks, getting closer to the buds that are beginning to swell. That is why active pest control begins in early spring.

The viburnum aphid causes damage to the entire area, but the main habitat is viburnum bushes. All the main means of struggle are used on them.

There are two main stages in the fight against black aphids.

  1. Creating the most unfavorable conditions for laying eggs of the last, wintering generation. To do this, you have to cut out without regret all the basal shoots, which abound in viburnum bushes. It is optimal to carry out such thinning of the base of bushes in the second half of summer.
  2. Spring treatment of bushes against pests using chemicals or folk remedies.

In the first days of spring, before using any pest control, the trunks of viburnum bushes are cleared of exfoliated old bark - most pests hibernate under it. After all the debris has been removed, the ground under the bush is watered with hot water.

Application of pesticides

The first treatment is carried out as soon as the spring sun warms up. During this period, pests emerge from hibernation and begin moving towards the kidneys. The most effective drugs include:

  • "Aktara";
  • "Decis";
  • "Prestige";
  • "Karbofos";
  • "Fufanon."

All of them contain either neonicotinoids or organic phosphorus. They are also applicable in the fight against other viburnum pests - sawflies, gall midges, and viburnum leaf beetle. Prepare working solutions in accordance with the manufacturer's instructions.

Viburnum should be sprayed against pests in dry, windless weather using personal protective equipment.

Good results are obtained by treating viburnum with a Nitrafen solution at the rate of 200 g of product per 10 liters of water. The drug also needs to be sprayed on the homes of ants that carry aphids.

It is permissible to poison pests with chemicals only in early spring, since later application will harm pollinating insects, especially bees.

Folk remedies

The fact that folk remedies are less effective in combating aphids is a fairly common misconception. Their effectiveness is no lower than industrial pesticides if they are prepared and applied according to all the rules. At the same time, solutions prepared according to “grandmother’s” recipes can be used throughout the entire growing season. But it is better not to wait until the pest has firmly established itself on the viburnum, but to spray the affected plants immediately after detecting the pest.

  • Soap solution

Prepared from laundry or green soap - 300 g per bucket of water. The treatment is carried out 2-3 times a week, after washing the bush with water from a hose under moderate pressure. Instead of soap, you can use one of the most inexpensive washing powders.

  • Ash infusion

A glass of ash is brewed with a liter of boiling water and left for a day. Then add 40-50 g of soap or washing powder, bring the volume to 10 liters. Spray viburnum once a week.

  • Ammonia

The solution is prepared from 20 ml of alcohol and a bucket of water. Viburnum is treated against pests twice, less often - three times, the interval between spraying is 2 weeks.

  • Tobacco infusion

250 g of tobacco or shag are infused in 5 liters of water for 2 days. Then filter, add 5 liters of water and treat the bushes.

  • Pharmaceutical chamomile

Take 1 kg of dried flowers in a bucket of hot water and leave for 12 hours. Strain the infusion, add 2 parts water to 1 part infusion. The plants are treated with the prepared solution immediately after mixing.

  • Pyrethrum (Caucasian chamomile)

300 g of crushed dried flowers are poured with a small amount of boiling water, left for 2 hours, filtered, water added to 10 liters and immediately sprayed with viburnum - the herb successfully fights many pests of garden crops.

Dried pyrethrum flowers can be purchased at pharmacies or garden centers under the trade name Persian Powder. The manufacturer indicates recommendations for use on the packaging.

  • Needles

Pine or spruce needles are crushed and steamed with boiling water at the rate of 200 g of dry raw material per liter of water. The infusion is kept tightly sealed for two days, after which the affected bushes are sprayed with it.

  • Henbane black

If there are thickets of this plant nearby, take young rosette leaves (about 200-300 g), pour a bucket of hot water and leave for 13 hours. Before spraying, add 30-50 g of liquid soap to the infusion.

Black henbane is a poisonous plant; be careful when working with it.

How to treat viburnum for pests

How to spray viburnum against pests, if we talk about chemicals, then the following are suitable:

  • Arrivo;
  • Fufanon;
  • Syngenta "Aktara";
  • Commander;
  • Corado.

How to protect viburnum from pests without chemicals

Biological preparations include planting plants around viburnum that can repel insects.

  • Chamomile
  • Garlic
  • Onion

After all, insects navigate in space by smell. Certain plants emit aromatic substances that repel pests.

For your information. Finding food for pests becomes much more difficult if there are too many other plants around, distracting them from their original goal.

Mechanical methods include spraying the plant with strong pressure of water from under a hose.

It is better to do all this before the buds open, as this will help reduce the number of larvae that have survived severe frosts.

You can use decoctions of potatoes, capsicum or celandine.

For your information. A ladybug or hoverfly will cope with the destruction of pests. They will only feed on insects, but they will not be able to harm the viburnum.

Folk methods of struggle

Some gardeners adhere to natural methods of pest control.

One of the simplest and most accessible methods is a soap solution of laundry soap.

Please note that it is easier to dissolve soap shavings

This method cannot harm humans. If you want to enhance the effect, you can add soda, ash, tobacco, or tomato tops.

Soap solution with soda

The method of preparing it is quite simple: in a bucket of water you need to mix half a bar of laundry soap and 10 tablespoons of soda.

The effect after spraying can be seen in the evening.

Soap solution with ash

It is a known fact that ash can cause severe harm to the skin of insects. Therefore, it is also a fairly popular folk method in the fight against parasites.

Advice. After spraying the plants with an ash solution, you can fix the effect with a soap solution. In this case, you will see the results of use very soon.

Tobacco leaf solution

Method of preparation: add a couple of red pepper pods to 200-300 grams of dry tobacco leaves and add water. Leave to infuse for a day.

To enhance the effect, you can add a little soap shavings and a couple of tablespoons of ash. Such a solution is capable of killing all treated insects in the shortest possible time.

Tops solution

This solution may include both potato and tomato tops. Chopped greens are poured into a bucket of water. Insists.

After this, you should boil it a little over the fire, cool, and add soap shavings.

Near the viburnum, you can also plant plants that will unnecessarily attract attention to themselves, diverting it from the viburnum bushes. These include:. These include:

These include:

  • Begonia;
  • Nastrium;
  • Mallow;
  • Linden.

These plants are a real paradise for parasites. Keep this in mind when planning your garden plot.

Sparrows, tits and warblers can also become your helpers in the fight against unwanted insects. You can attract them with the help of drinkers and feeders on your territory.

These birds will be happy to clear the land of unwanted guests.

Unfortunately, not all folk remedies are capable of removing pests 100%, but, as practice has shown, not even all chemicals cope with this.

Therefore, if you want to reliably achieve results in the shortest possible time, you should combine all the methods available to you.

Pest Prevention

The most reliable way to prevent viburnum from diseases and pests is to regularly inspect it.

  1. Carefully inspect each leaf, inflorescence, and stem itself. If you see that the plant has begun to change shape, color, rot or dry out, you must immediately look for the problem and take measures to eliminate it.
  2. As a preventative measure, you can safely use the above-described decoctions and self-prepared soap solutions.

In this article, we examined in detail all the insects that can harm viburnum, the types of control against them, as well as ways to prevent diseases of the plant itself.

Follow these effective tips, and then your viburnum will never get sick.

Professional products

If the viburnum is attacked by aphids, you can fight it with professional chemical preparations based on insecticides. The active components of the product block nerve impulses, causing paralysis and early death. The minimum dose of poison is enough to cause death.

The advantages of this method of control are high efficiency, quick results, preservation of properties for up to 20 days. The insecticidal agent destroys adults and larvae of all ages.

Insecticides for insect pests

Which drug to use is an individual decision. All of them act immediately, mass death of aphids is observed within a week, and retain their properties for up to 20 days.

On a note!

Before the buds open, it is recommended to treat all shoots with Nitrafen paste. You can treat viburnum against aphids during flowering using any insecticidal spray method.

Insect pests of viburnum

Black viburnum leaf roller aphid

The black viburnum leafroll aphid (Aphis viburni) is a small sucking insect of dark brown, black color. It lays eggs on the bark of branches near the buds, where they overwinter. When the leaves bloom, the first generation larvae emerge from the eggs. This insect pest of viburnum feeds on the sap of young leaves; when the pest population is large, the leaves curl and dry out.

Control measures. Spray viburnum bushes against aphids with one of the following preparations: Fufanon, Inta-Vir, Fitoverm.

Viburnum leaf beetle

The viburnum leaf beetle (Galerucella viburni) is a light brown beetle. The larvae are greenish-yellow, with a black head and black spots on the back. In May they feed on young leaves, roughly eating them. In early June, the larvae pupate in the soil. After 3-4 weeks, beetles appear and eat leaves, shoots and berries. In August, females gnaw holes in young shoots and lay eggs in them, covering them with lids.

Control measures. Trim dead shoots containing egg-laying plants. To combat these viburnum pests, you need to spray the bushes in May, when the larvae hatch, or in early August, when the beetles appear, with the following preparations: Fufanon, Iskra, Inta-Vir, Actellik and Kemifos.

Types of pests

Various pests can attack the viburnum bush, and each of them is characterized by its own life cycle and, accordingly, the period of time when this particular insect can be especially dangerous for the garden plot. At the same time, existing insecticides are not equally effective against various parasites.

Did you know? Science knows more than four thousand different species of aphids, about a quarter of which live in Europe. Many representatives of the aphid superfamily are monophages or oligophages (they parasitize one or more plants), but there are also omnivorous varieties of these small pests - polyphags.

Therefore, in order for the fight to preserve the future harvest or the healthy appearance of the tree (if we are talking about an ornamental variety of viburnum) to be effective, the gardener needs to clearly know which pests can eat the plant during the flowering period, and, if possible, be able to distinguish them from each other , guided by characteristic symptoms.

Aphid

Aphids are the worst enemy of a garden plot, and it is quite difficult to find a crop that this parasite would not interfere with growing and bearing fruit normally. A big fan of eating viburnum is the black viburnum aphid. The adult is a tiny flea of ​​a dark red or dark brown color. Like all representatives of the superfamily, it feeds on sap sucked from the green organs of the plant. As a result, the affected leaves begin to curl, young shoots become deformed, and the entire bush takes on an ugly appearance.

Aphid
The period of activation of the harmful effects of aphids occurs in spring and early summer, that is, it may well coincide with the flowering of viburnum.

It is in May and June that insects are visually very clearly visible on the apical shoots of the bush, so identifying the pest is not at all difficult. A characteristic sign that it was aphids that began to damage the viburnum is also the appearance on the stems and leaves of a characteristic sticky coating secreted by these insects.

Aphids on viburnum

By the end of summer and beginning of autumn, aphids begin to spread, seeking to occupy new territories, and after a few weeks, winged females lay eggs directly on the branches, in close proximity to the buds. Having overwintered in this way, the larvae hatching from the eggs begin the next life cycle in the spring.

Viburnum leaf beetle

The viburnum (or, as it is sometimes not quite correctly called, viburnum) leaf beetle in the adult state is a light brown beetle with a body length of about 5 mm. The leaf beetle begins to parasitize viburnum in the larval stage, which becomes active in early spring. It is quite difficult to notice the parasite on the bush, since the larva is attached to the underside of the leaf blade. Under favorable conditions, the pest is able to gnaw the entire leaf down to the last vein in a short time.

Viburnum leaf beetle
As a result of damage by the leaf beetle, viburnum is greatly weakened and often freezes during the winter.

The transformation of the larva into an adult occurs in the soil, where the caterpillar slides at a certain stage of its development. Having reached the surface, the adult resumes the process of eating the green part of the viburnum, but this time the beetle is already quite visible to the naked eye and parasitizes on the front side of the leaves. If the plant manages to withstand frost, in the spring it again begins to be affected by beetle larvae hatching from eggs, which the female lays deep in the wood in the fall.

Viburnum leaf roller

Traces of the vital activity of this pest are manifested in the characteristic curling of the leaves into a tube, inside which the caterpillar settles. The larvae begin this process in early spring, secreting a substance similar to a cobweb and knocking it into sticky pellets.

leaf roller
Like the viburnum leaf beetle, the leaf roller feeds on the pulp of leaves and is capable of eating them in huge quantities.

By mid-July, the caterpillar with a dark brown head, yellow sides and a gray or green body covered with whitish hairs turns into a pupa, after which it ceases to pose a danger to the plant for some time. However, even for insecticidal preparations, the insect tightly wrapped in a leaf plate becomes inaccessible during this period, so it is necessary to fight the leaf roller before the pupation process occurs.

We recommend that you learn how to get rid of caterpillars on viburnum.

Other pests

The three parasites mentioned above are the most likely enemies of the viburnum bush in the spring. Among other pests that a gardener may encounter while growing a plant, we can also mention:

  • gall midge (viburnum and honeysuckle);
  • moth (cap moth and fox moth);
  • honeysuckle spiny sawfly;
  • greenish lobed moth;
  • comma-shaped scale insect.

Viburnum Pests
However, the listed insects still appear on bushes much less frequently than aphids, leaf beetles and leaf rollers. At the same time, spider mites pose a serious danger to viburnum.

Many folk and chemical means of protecting viburnum from pests are effective against both insects and ticks, but in general, to combat arachnids, special preparations are used, which are called acaricides (“ἄκαρι”, read as “akari”, translated from ancient Greek means "mite").

Did you know? Ticks, contrary to popular belief, are not insects. They belong to the class of arthropods and are the closest relatives of spiders (the main difference between insects and arachnids is that the former have six legs, and the latter have eight).

Folk recipes


Folk remedies for aphidsFolk remedies for aphids
The fight against aphids on viburnum is carried out by all known methods. Folk remedies are very diverse and unique, making it possible to do without chemicals.

  • In order to save the viburnum and completely overcome black aphids, it is necessary to cut out the shoots that are located at the roots in late autumn. It is in this place that the aphid lays eggs and leaves them to overwinter. In the spring, when the bush begins to bloom, pour hot water onto the soil at the root.
  • Natural enemies of insects - ladybugs, lacewing larvae, and hoverflies - can destroy aphids.
  • You can spray viburnum with a solution of onion peels. Pests cannot stand this smell and try to escape from it as quickly as possible. 200 g of husk is combined with 500 g of wood ash, 200 g of tobacco powder. Pour in 10 liters of water. Leave to infuse for 5 days. Before use, add laundry soap and filter the finished product. It is necessary to spray viburnum in May even before the first leaves bloom, or during the flowering period. Repeat the procedure every week until the pests disappear.
  • Wood ash, spices - cinnamon, red and black pepper, and soap solution are added to the water. Pour the mixture into a spray bottle or spray bottle. The first time you need to spray the viburnum is in the spring, then this should be done every month with a break of 7-14 days.
  • You can get rid of aphids with a strong tincture of garlic, tobacco, and pine needles. They can be used together or separately. 200 g of raw materials are poured into 1 liter of water and boiled for half an hour. Cover with a lid and leave for 5 days. Strain the finished preparation and add soap. Spraying is carried out.
  • Grind potato tops, tomato tops or marigolds. Pour 10 liters of water and boil for half an hour. Leave for at least a day. Viburnum is sprayed every 3 days during active control. For prevention, once every 2 weeks. It is allowed to prepare the product in reserve. The longer it sits, the greater the concentration of active components.

On a note!

Aphids on viburnum buldenezh are exterminated by the same means. This is an ornamental bush 3 m high with beautiful buds of white flowers that adorn the bush in May.

Also used against aphids:

  • ammonia;
  • soda;
  • milk and iodine;
  • vinegar;
  • celandine;
  • mustard;
  • vodka;
  • green soap;
  • Birch tar;
  • boric acid.

Folk methods of struggle

Many gardeners prefer not to use chemicals to control pests. And there are many folk methods: in addition to a decoction of the garden plants listed earlier, spraying with a soap solution is recommended. This solution is prepared using laundry soap or tar soap. You just need to dissolve the soap in water, about 100 grams per 1 liter of water, preferably warm.

Please note: it is much more convenient and faster to dissolve soap shavings.

This method is absolutely safe for humans. For greater effectiveness, it is recommended to add to the solution:

Methods for preparing each solution are discussed below.

Soda-soap solution

The effect of using this product will be noticeable by the end of the day. To prepare, you need to mix soap with water (1/4 or 1/2 of a bar of soap per bucket is enough), then add soda at the rate of 1 tablespoon per liter of water. You will need about 10 tablespoons of soda per bucket. Mix thoroughly and spray the plant thoroughly.

Preparation of soda-soap solution for spraying

Ash solution

Wood ash is highly irritating to the skin of insects, making it excellent for pest control. The soap solution will help fix the ash solution on the leaves.

First you need to sift 300 grams of wood ash, add it to a bucket filled with 10 liters of water and put it on fire. Cook for half an hour. Then cool slightly and add 40 grams of soap.

Advice! There is no need to make this product in advance; it is better to prepare it immediately before use.

Tobacco solution

To prepare, you need to mix 200 grams of dry tobacco leaves with three pods of hot pepper and pour a bucket of water over everything. Insist for a day. Then add 100 grams of laundry soap, 3 tablespoons of wood ash (can be replaced with cinnamon) and mix. This solution can quickly remove pests.

Tops solution

To prepare the solution, you can use potato or tomato tops. It is necessary to chop 3 kg of fresh herbs, add 10 liters of water and leave for at least 6 hours. Then put on the stove, bring to a boil and cook for half an hour. Then cool, add 50 grams of soap and use.

Using a soap solution to spray viburnum is safe for humans and is accessible to everyone. However, it is not always possible to cope with harmful insects only with the help of folk remedies. Store-bought products are much more effective, but they also cannot destroy all pests the first time. For maximum effectiveness, it is worth using folk remedies in combination with store-bought ones.

Important: due to the need for chemical treatment, you should not plant viburnum next to the beds; eating such a crop can be dangerous.

Preventive actions

To prevent the appearance of aphids on viburnum, every spring you need to clean the bush of old peeling bark, under which there may be masonry, and whitewash the trunk with lime. You should also regularly cut out root shoots and tops.

If there are ants in the garden that contribute to the development of aphids, it is necessary to get rid of them by pouring boiling water over the areas where they accumulate. But some insects, such as ladybugs, should be attracted to the garden because they eat aphids.

Viburnum pests and their control

Like other garden crops, viburnum is a target for many pests. Leaf-eating insects can cause considerable damage, destroying the leaves and flowers of the plant.

Viburnum is one of the few fruit crops that can fully develop in the shade. Therefore, in order to reduce the risk of pests, choose shady places for planting.

However, you can get rid of this scourge by carefully monitoring the condition of the viburnum and promptly treating the bushes with special preparations. Read this article on how to deal with viburnum pests.

Main diseases of viburnum, treatment methods

Various diseases to which scorch is susceptible can overcome it year after year, and the number of them is amazing. The whole difficulty is that it is very difficult to find out the cause of the disease, even with a thorough diagnosis. We can only draw a single general conclusion that the plant has undergone a viral attack when spots or stripes appear on its leaves that differ from its natural color.

Did you know? Viburnum is an excellent honey plant. It produces a lot of nectar.

Powdery mildew

Viburnum leaves are rarely affected by this disease. This type of fungus affects viburnum only in the summer, when it is rainy and cool. Only at a time when conditions for pore maturation arise. To remove the unpleasant disease, the following preparations for viburnum should be administered: “Topaz”, “Strobe” or a copper-soap solution. Wood ash, which has been cleared of coal particles, also helps in this case. Three kilograms of ash should be poured into a bucket of hot water and left for two days. Viburnum that is sick with powdery mildew should be treated twice a month.

Leaf spotting

Gray spots of various shapes with a brown or purple border appear on viburnum leaves.
On the underside of the leaf, the spots are olive-gray in color. By September, dark dotted fruiting bodies of the fungus begin to form on the dead tissue. Then the spots crack, dry, and the middle falls out. Dealing with spotting is quite simple. It is necessary to remove all affected leaves from the bush. During the budding period, it is necessary to spray the viburnum with Bordeaux mixture or copper oxychloride.

Did you know? Viburnum is a health worker among plants, as it produces a large amount of phytoncides that resist harmful organisms.

The most common pests

Viburnum has many admirers not only among people, but also among insects. However, the preferences of the latter are destructive for her. The following are the pests that can cause the greatest harm to viburnum, as well as how to get rid of them and save the plant.

Black aphid on viburnum, how to fight

These small bugs are easy to notice: they are brown, almost black in color (less often crimson-brown) and accumulate in large quantities on the stems of the plant. They usually lay eggs in the bark of the viburnum tree, 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. Over time, they dry and curl, and the shoots change shape.

In general, aphids attack three times a year, starting in May. During this month it is necessary to start treating the plant with insecticides. Then the aphid larvae grow and turn into flying insects that are able to fly to neighboring plants. In August, aphids begin laying eggs, which can successfully overwinter, despite the frost.

Black aphid on viburnum

Measures to combat viburnum aphids include the destruction of root shoots, where the largest number of eggs are laid. How can you treat viburnum against aphids? The plant should be sprayed with chemicals:

  • Fitoverm,
  • Akarin or Agravertin CE,
  • Aversectin,
  • Intavir.

It is also a good idea to treat the plant with a solution of laundry or tar soap.

Important! It is better to do the first treatment before the buds open, this will help reduce the number of overwintered eggs.

What to do if the use of chemicals in a given location is not possible? Folk remedies will help. For spraying, you can use decoctions prepared from other plants. Potato tops (1.2 kg of green ones per 10 liters of water), pepper infusion (1 kg of capsicum per 10 liters), celandine (3-4 kg of fresh celandine per 10 liters) are suitable for this.

It will also be useful to purchase or attract beneficial insects that destroy aphids on viburnum. This is a ladybug, a hoverfly or a goldmine larva. The insects will eat the pests, but the viburnum will not be touched.

Green lobed moth

The caterpillar has a yellow-green color with a dark red stripe along the body, the same dots and spots. Prefers to eat exclusively flowers and gnaw out flower ovaries. Particularly active between May and July. Over the summer, two generations of butterflies may appear. The moth is most often found on the ornamental shrub Buldenezh. In addition to viburnum, it can also harm other garden shrubs, such as lilac and buckthorn.

On a note! Pest control must be carried out twice: in the spring, before the viburnum begins to bloom and after it has finished. 10% Karbofos is suitable for processing.

Viburnum leaf beetle

The viburnum leaf beetle is a large brown beetle. Prefers to hide a clutch of eggs in young shoots of viburnum. The larvae have a black head and a dirty gray body. Some people confuse the leaf beetle caterpillar with a worm. The larvae emerge from the eggs at the end of spring and begin to eat young leaves. You can notice that the leaf beetle caterpillars on the viburnum have eaten all the leaves. They are able to completely eat a leaf, leaving only a skeleton mesh instead. You can notice them on the back of the sheet: the caterpillars hold firmly and are not so easy to shake off.

Please note: this pest has a truly brutal appetite; in a few days the larvae are capable of destroying a large number of viburnum branches.

At the beginning of summer, the larvae hide underground and turn into beetles. They have a yellow-brown color. The beetles not only eat viburnum leaves, but gnaw holes in them. In this case, you can notice that the viburnum leaves have holes. Now leaf beetles live on the upper part of the leaf. After the leaves they move to inflorescences. their actions can lead to the complete death of the plant and the crop.

Favorable weather for the leaf beetle is rain, damp and cold. Under such conditions, the number of beetles may increase, which will cause considerable harm to the viburnum.

These parasites are capable of almost completely destroying plantings, and removing them is very difficult. If no action is taken, the weakened plant may not survive the winter.

To combat this beetle, you need to remove dried and damaged shoots in the fall, as well as leaves with larvae. Treat the plant in the spring, when the leaves have not yet blossomed, and in August. The drug Intavir is suitable for this: you need to spray the plant twice with an interval of 7-10 days. During the growing season, it is recommended to spray viburnum with an infusion of hot pepper (a kilogram of fresh or 0.5 kg of dried crushed pods per bucket of water), an infusion of tomato tops (4 kg of fresh herbs per bucket of water) or a decoction of chamomile (3 kg fresh or 1 kg dried per bucket of water ). It will also be useful to remove in the spring those shoots in which egg laying is visible. The trimmings should be removed away and burned immediately.

Viburnum leaf roller

The larvae of this pest are gray or green caterpillars, which have a yellow tint on the sides. The entire body of the caterpillars is covered with light hairs. They become active in the spring. They actively eat the buds and young leaves of the plant. In addition, they wrap the leaves with cobwebs and knock them into a ball.

Leaf roller caterpillars are capable of real wrecking: in a short period of time they can eat huge quantities of leaves and inflorescences, which negatively affects crop yields. To prevent the caterpillars from eating all the viburnum leaves, you need to start fighting them in time.

Note! To destroy the viburnum leaf roller, you need to collect and burn all the caterpillar nests. Then spray the plants with 60% Nitrophen paste (250 g per bucket of water). This must be done before the leaves bloom. Then you need to treat the viburnum with 10% Karbofos.

Viburnum gall midge

This parasite only harms viburnum flowers. After wintering, adult individuals emerge from cocoons in the upper layers of the soil and lay their eggs inside the bud. The bud is greatly deformed, increases in size and changes color to red. Because of all this, the flower does not open and the yield of viburnum is greatly reduced.

Drugs

To combat aphids on viburnum, you can use chemicals. Today they can be contact, intestinal and systemic. Each of them has its own advantages and disadvantages

So, with the help of contact preparations, it is possible to make life easier for viburnum, because the active components of these compositions penetrate through the body and destroy aphids.

The most effective drugs remain:

  • Arrivo;
    Arrivo
  • Fury;
    Fury from aphids
  • Fufan (how to use fufanon against weevils on strawberries is indicated here);
    Fufanon for aphids
  • Karbafos.

But they have one drawback - those insects that could not be killed begin to actively reproduce, sensing danger.

Intestinal drugs penetrate the digestive system through the nutritional organ. Insects that fed on the drug die immediately. Among intestinal drugs, Confidor and BI-58 Novy remain effective.

The action of systemic drugs is aimed at actively penetrating the components into the tissue of the tree, making its sap poisonous. Such products should be used when treating tall trees, since spraying the crown is not so easy. Such preparations are not afraid of rain, as they are quickly absorbed by the leaves. But system tools have one drawback. You have to wait 2-3 weeks for a positive effect to be achieved.

Biological preparations can also be used to control aphids on viburnum. the most effective remain:

  • Fi-toverm;
    Fitoverm
  • Akarin;
    Akarin
  • Agravertine CE;
  • Aversectin.

When developing these drugs, we used the waste products of the soil microorganism aversectin. You can also purchase products based on cypermethrin and permethrin - Iskra, Intavir. Their peculiarity is that they quickly decompose and do not lead to the development of addiction in insects. But they have a minus - if the drugs are stored incorrectly, they will lose their properties. But you can learn how to use a spark from a weevil on strawberries from this article.

Autumn pruning

Pruning viburnum is an important step in caring for shrubs. If you do not carry out these manipulations, the bush will become very dense, and the shoots will begin to compete with each other. This will lead to their growth upward, the bush will become tall, and the yield will decrease. The berries will be difficult to pick.

Pruning is done either in the spring, when the snow melts. Or in the fall before the very first frost. But it is better to use the first method.

First, any broken shoots that appear due to the harvesting process are cut off. Then all dry growth and thin branches are removed. Thin branches are those whose diameter when cut is less than a pencil. Fattening shoots are also eliminated, as they begin to grow deeper into the crown of the bush, have wide internodes and do not bear fruit.

In general, pruning this shrub does not have a strict step-by-step plan, unlike an apple tree, for example. An individual approach can be applied to each plant to reduce the degree of rust by trimming the lateral branches that grow from the outside of the crown.

Let me explain: if the shoot is more than two meters high and has many branches, then at the level of one and a half meters one of the branches can be shortened. The result will be a viburnum bush with a wide crown, small and not very dense vegetation. This will provide access to convenient harvesting.

When the plant reaches the age of ten years, radical pruning can be done. In this case, cut off all the shoots near the ground at a distance of ten or fifteen centimeters, leaving part of the growth and a few buds. Over time, new shoots begin to grow on these branches. This is called a hive update. You need to choose five or six and cut the branch to the side when they grow to one and a half meters.

It is worth remembering that after pruning the bush, all areas of the cuts must be isolated using a garden varnish.

Trimming

Viburnum pruning is carried out for the purpose of sanitary cleaning, rejuvenation and crown formation. When sanitary pruning of shrubs, dry, broken and diseased shoots are systematically removed. All viburnums have a long period of shoot growth, the durability of its trunks is more than 30 years. Therefore, anti-aging pruning on viburnum is carried out no more often than after 5-7 years. Old branches are cut down to the point where stem shoots appear, leaving about 20-25 strong and large shoots. This thinning of the viburnum crown can be done in winter or early spring, in early April. It is recommended to cut bushes with weakened flowering “to the stump” at a height of 15-30 cm from the root collar. After pruning, strong young shoots develop from dormant buds, and the bush is completely restored. For abundant flowering of viburnum, it is recommended to pinch out strongly growing young shoots.

General knowledge

During early autumn, which in our country begins at the end of August and goes to the very beginning of September, the fruits of viburnum begin to ripen. It is best to start collecting them at the very beginning; you just have to wait until the berries in the inflorescences are fully ripe. It is easy to determine their level of ripeness: a ripe berry will release bright red juice when pressed; unripe fruits have a light-colored juice.

Harvesting viburnum ahead of schedule will only be justified if you need to transport the fruit over long distances. When you decide to immediately send the fruits for processing, it is better to start picking only after final ripening.

It is worth noting that viburnum fruits tend to ripen after pruning, but this is typical only for fully colored berries, which become soft. But if you pick the berries when they are hard and green, you won’t be able to let them ripen.

It is most convenient to harvest not one berry at a time, but whole clusters. Then each family member and garden worker will be able to collect up to a hundred kilograms of fruit in one day. By the way, this amount of berries can be collected from ten bushes.

After harvesting, Buldenezh viburnum needs to be fed to give it strength to survive the winter. It is worth understanding that in the autumn you cannot use fertilizers that contain nitrogen. This is due to the fact that they can lead to the active growth of viburnum shoots. They will be very young and will not be able to survive the winter.

Therefore, gardeners recommend using superphosphates or potassium salts. Use about twenty grams per bush. But it is best to replace mineral water with regular compost, which will additionally serve as mulch and retain moisture.

Shelters and additional protection conditions are not required for viburnum; preparation for winter will always be successful without these measures. In rare cases, some parts of young shoots may be affected by severe frosts.

Chemicals for aphids on viburnum

Baba Tanya’s favorite insecticide, which she uses to treat all plants against insects, is “Intavir” (analogous to “Inta-Ts-M”). That's what they used.

Baba Lyusya uses another chemical to combat aphids and other pests: Tan-rek.

In general, in modern stores the range of insecticides is quite wide. And for convenient spraying, we always use the Zhuk garden sprayer. As an alternative, you can spray chemical solutions from a spray bottle or even from a broom. This is not so convenient, but as an emergency measure it will do

Pest Prevention

The most reliable way to prevent viburnum from diseases and pests is to regularly inspect it.

Viburnum Pests

  1. Carefully inspect each leaf, inflorescence, and stem itself. If you see that the plant has begun to change shape, color, rot or dry out, you must immediately look for the problem and take measures to eliminate it.
  2. As a preventative measure, you can safely use the above-described decoctions and self-prepared soap solutions.

In this article, we examined in detail all the insects that can harm viburnum, the types of control against them, as well as ways to prevent diseases of the plant itself.

Follow these effective tips, and then your viburnum will never get sick.

Viburnum leaf roller Description

The larvae of the viburnum leaf roller are caterpillars of a grayish or greenish-olive color, which, immediately after emerging in the spring, begin to actively eat the buds and young leaves of the viburnum.

leaf roller on viburnum

At the same time, they entangle the leaves with cobwebs, knocking them into a ball. In mid-summer, the caterpillars pupate.

How to deal with viburnum leaf roller

  • Mechanical collection of nests along with pests and their subsequent burning will help get rid of caterpillars.
  • It is also recommended to treat the viburnum bush with nitrafen paste before the buds open, and with karbofos after they open.
  • During the period of mass appearance of insects, it is necessary to apply 0.05% Inta-Vir or Decis (dissolve 1 tablet in 10 liters of water). After two weeks, the procedure is repeated.

Chemicals

Options for chemical treatment of viburnum leaves are as follows:

Before the bush begins to flower, the leaves are sprayed with a 60% solution of nitrafen in a ratio of 200 grams of liquid per 10 liters of water.

From the beginning of the spring period and a month before harvesting the fruits, a solution of karbofos or funanone is used. Be sure to use personal protective equipment.

Reproduction methods

Viburnum takes good cuttings, produces layering, divides the bush and propagates by seeds.

Green viburnum cuttings are harvested during the flowering period (June-early July), when they are elastic, do not break when bent, but spring back. They are cut with 2-3 nodes, 7-10 cm long. An oblique cut is made at the bottom and the leaves are removed, the cuts should be smooth. Cuttings take root well if they are treated with Kornevin or Heteroauxin. After which they are planted to a depth of 1-2 cm in a greenhouse filled with coarse river sand mixed with peat in a 1:1 ratio. The greenhouse should be covered with glass frames or plastic wrap until the cuttings take root. Rooting occurs after 3 weeks at a temperature of +27+300C and a humidity of 70%. During this period, the substrate is regularly sprayed with water. Until the end of August, while the roots are strengthening, the frames are replaced with fitting panels. For the winter, the cuttings remain in the greenhouse. They are covered with dry leaves or spruce branches, and in the spring they are planted in open ground. After 2-3 years, viburnum plants bloom.

Cutting viburnum cuttingsTrimming viburnum cuttings

To obtain layering, in the spring, annual shoots of viburnum are bent to the ground and radially laid out in shallow grooves, but the tip of the shoot remains on the surface. The spread out shoots are pinned with 2-3 hooks and sprinkled with loose soil or humus. For better root formation, the bark above the backfill area is tied with wire or cut. By autumn, roots develop on each horizontal layer, and young plants form from the buds, which are cut off with pruning shears and transplanted to a permanent place.

In spring or autumn, a young viburnum bush is dug up, then it is carefully divided into 2-3 parts, so that at least 2-3 renewal buds remain on each plant. This is how viburnum is propagated by dividing the bush.

Viburnum boule de neige from cuttingsViburnum seedlings

For propagation by seed, large viburnum seeds are separated from the pulp before sowing. Then they are washed in water and dried in a ventilated area. Viburnum seeds can be sown in the fall. When sowing freshly harvested seeds into the ground in the fall, viburnum shoots appear only after a year. To speed up their germination, pre-sowing treatment is recommended - cold stratification. To do this, the seeds of Viburnum Viburnum and Viburnum Sargent are placed in damp sand and kept at a temperature of +4+50C for 5-6 months. For Viburnum Bureinskaya, 3-4 months of stratification is enough.

You can carry out warm-cold stratification of viburnum seeds. To do this, seeds immediately after harvesting the fruits (in September-October) are placed in boxes with damp sand and stored at a temperature of +20+28°C for 2 months, and then transferred until spring to a colder room with a temperature range from 0 to + 5°C. When sowing, the seeds are deepened into the substrate by 3-4 cm. In the spring, friendly shoots appear, and the seedlings dive into the garden bed. Viburnum seed germination lasts up to 2 years.

Pests and diseases of viburnum, methods of treatment

The main pests of viburnum include:

1. Viburnum leaf beetle

Beetle, light brown in color, up to 6 mm in size. With the onset of August, the plant begins to lay eggs in the recesses of the shoots, in shocking quantities - up to 700 pieces. In winter, the young shoots dry out, but the laid eggs quietly overwinter. In May, the eggs mature and the larvae hatch from them, and immediately begin to destroy young shoots and leaves. In June, the larvae burrow into the soil to pupate. Already with the onset of July, beetles appear and eat the leaves.

How to deal with viburnum leaf beetle?

  • It is necessary to prune young shoots in autumn and spring, and you also need to immediately remove leaves on which there are larvae;
  • In the spring, even before the leaves bloom, the bush must be treated with: Fafanon, Karbofos, Akttelik, Aktara. You also need to take Intavir twice with an interval of up to 10 days.

2. Viburnum aphid

Leaf roller aphids are black in color. Dimensions reach only 7mm. Eggs that have successfully overwintered hatch into larvae in the spring. Aphids are capable of active reproduction and feed on plant juices. Viburnum foliage begins to curl, deform and dry out.

How to deal with viburnum aphids?

It is necessary to carry out the first treatment even before the buds open, this will significantly reduce the number of eggs that managed to survive the winter. The drugs must be alternated: Fufanon with Karbofos. It is also possible to use biological drugs: Iskra, Intavira, Akarina.

3. Chekhlik moth

The method of disposal is no different from viburnum aphids. It is necessary to prune young shoots with the onset of spring and spray the bush with Karbofos, a solution of 90g/10l of water.

4. Comma scale insect

To get rid of this pest, it is necessary to do preventive pruning in autumn and spring, spray the viburnum with a solution of Karbofos, and with the onset of August, spray with Fufanon and Iskra.

Viburnum gall midge Description

A peculiarity of this pest is the fact that it causes damage exclusively to viburnum flowers. It spends the winter hidden in cocoons in the upper layers of the soil. During the period when the buds appear, adult insects emerge from the surface and begin to lay eggs inside the buds. The hatched larvae feed on the pulp from the inside, thereby disfiguring the shape of the bud.

viburnum buds

Naturally, in such conditions the flower does not bloom and the yield of viburnum is significantly reduced.

Viburnum and honeysuckle gall midge

These viburnum pests attack plant flowers. The larvae of the viburnum gall midge are white, and the honeysuckle gall midge is red. They spend the winter in the upper soil layer, wrapped in spider cocoons. Adult gall midges reveal themselves when the buds are exposed. Female gall midges like to lay eggs inside the bud, and the larvae also develop here. Due to this, the buds become ugly, significantly increase in size, swell, turn red, the corolla thickens, and the pistil and stamens are greatly retarded in development, the flowers cannot open. Viburnum pests produce only one generation.

Control measures

To combat gall midges, it is necessary to loosen the soil in early spring and late autumn, and before and after flowering of the viburnum, it is necessary to spray with 10% karbofos at the rate of 100 g of the substance per bucket of water.

Honeysuckle spiny sawfly Description

This insect harms not only viburnum, but also honeysuckle. Its larvae are olive-colored with a bright pattern on the back, as well as rows of spines. They spend the winter in the soil in order to pupate with the onset of spring and appear on the surface in the form of adult insects in full readiness for reproduction. At the same time, the leaves of the viburnum begin to bloom, where the sawfly hides its clutches of eggs.

The larvae that emerge from them cause damage to the leaves, gnawing them at the edges. If conditions are favorable for insect life, then viburnum bushes may be left with virtually no leaves.

Methods of combating the honeysuckle spiny sawfly

  • An effective preventive measure to prevent the appearance of these pests is deep digging of the soil in October-November, in order to thus get rid of the sawfly larvae overwintering in it.
  • Spraying with karbofos, which is carried out both before and after flowering, also gives good results.
  • If we talk about natural means of combating this insect pest, then you can use treatment of viburnum with a mixture of tobacco, onions and garlic or spraying with a decoction of wormwood.

Tools used

In order to help the crop fight against dangerous diseases and pests, gardeners use a wide range of different compounds. Conventionally, they can be divided into several categories.

Folk

Means for the treatment and destruction of insect pests can be made from various components present in human everyday life. Among the most effective it is worth noting:

  • liquid compositions based on laundry or tar soap;
  • decoctions from potato tops;
  • pepper infusion;
  • infusion of celandine.

Using the above remedies it will be possible to cure viburnum from powdery mildew. To prepare a decoction of potato leaves, you will need at least a kilogram of green mass, which is poured with 10 liters of water, infuse. To prepare pepper tincture, a kilogram of leguminous fruits is used, which are infused in 10 liters of water. To fight the disease with the help of celandine, you will need 3-4 kilograms of the plant - they are crushed and infused in a bucket of water.

The entire above-ground part of the viburnum will need to be treated with ready-made compounds. For effective action, repeat spraying is carried out after a week.

To treat powdery mildew, you can prepare a copper-soap solution with the addition of ash. After the product has been infused for about 3 days, it is recommended to spray the viburnum once every 2 weeks.

To cure viburnum from spotting and rot using folk methods, it is recommended to use an infusion of tomato tops, the preparation of which will require 4 kilograms of green mass and a bucket of purified water.

Treatment with chamomile decoction also demonstrates effectiveness. You can use fresh or dried culture. In the first case, 10 liters of water will require at least 3 kilograms of culture; dry chamomile should be used about 1 kilogram.

To treat viburnum, in addition to soap solution, you can use soap with the addition of soda. As a rule, to treat a plant from gray or fruit rot, use half a bar of soap per bucket of water and 1 spoon of soda for each liter of liquid.

A liquid composition based on ash will help get rid of most viburnum pests. If you spray a tree with a solution, you can destroy pests without much difficulty, since when it gets on the skin of an insect, the product acts as a strong irritant. To consolidate the result obtained, you can combine the treatment with treating the plant with a soap solution.

To prepare the composition, you will need to take at least 300 grams of wood ash per one garden bucket of water.

Another universal folk remedy for most pests is a tobacco solution for treating viburnum. To make it, you will need a bucket of water, about 200-250 grams of dried tobacco leaves, as well as a couple of pods of hot pepper. In order for the liquid to become suitable for processing, it must be allowed to sit for at least 24 hours.

To get rid of the honeysuckle sawfly, the gardener is recommended to spray a decoction of wormwood, garlic or onion decoction. To prepare a composition based on wormwood, about 700-800 grams of dry herb are used for one bucket of water. Garlic remedy can be made from crushed cloves; for onion broth you will need peels.

Chemicals

If the use of traditional methods does not bring results, and viburnum continues to hurt, you can purchase specialized store-bought products with a wide or narrow spectrum of action. You can treat a crop for powdery mildew with the following drugs:

Spotting on viburnum leaves can be overcome if the crop is sprayed with copper oxychloride or Bordeaux mixture. Bacterial spotting can be successfully treated with Abiga-Pik or Hom.

There are specialized chemicals that help cure crops from gray rot. Even at an advanced stage of the disease, it will be possible to help the culture if treated with Vectra.

Another problem, in addition to diseases, is insect pests. The fight against them is also actively carried out using the following store-bought chemical compounds:

Planting care

In the year of planting and subsequent years, caring for viburnum consists of loosening, weeding, regular watering and fertilizing. Mulching helps protect the soil and plant roots from overheating and reduces the growth of weeds, especially annuals, the seeds of which are carried in large quantities through the air. On soil free of weeds, mulch in the form of wood chips, bark, or peat is spread in an even layer (7-10 cm thick) around the bush. The best time to apply mulch is late spring, when the soil is still sufficiently moist but already well warmed up.

Every spring, a bucket of rotted manure or compost is added under each viburnum bush. Mineral fertilizing is carried out in the spring and before flowering. Approximate doses of fertilizer per planting hole are given below. For greater effectiveness, they can be dissolved in 1 bucket of water before application.

Fertilizer Dose, g
Ammonium nitrate 25-30
Potassium salt 10-25
Simple superphosphate 40-50
Double superphosphate 15-25
Complex fertilizer 65-75

Prevention

Of course, it is better to engage in prevention in time, so that you don’t have to suffer in search of an effective remedy to combat this scourge. To do this, you just need to follow a few simple rules:

  1. You can reduce the likelihood of the formation and spread of insects on viburnum by pouring boiling water over the clutch of ant eggs. Everyone knows that it is ants that contribute to the development of aphids. But how to combat woodlice insects in the garden, and what means should be used, is indicated in this article.
  2. Take measures that ensure good leaf turgor. If the green part is tight, then the aphids will not be able to bite through it.
  3. Sprinkle the crown, apply balanced fertilizers, regularly water and mulch the soil. When applying fertilizers, it is important not to overdo it with nitrogen compounds.
  4. Remove honeydew from leaves regularly. A sooty fungus may form on it, which will make the plant even weaker.
  5. Regularly remove overgrown parts of plants that have fairly soft tissue. This includes tops that fatten shoots and root shoots.
  6. In autumn and early spring, while the buds have not yet swelled, it is worth removing old and flaking bark from all trunks and branches. The trunks are whitened, thereby reducing the number of viable egg clutches.
  7. You can also bring ladybugs to the site, which are the evil enemies of aphids. But how the treatment for the Colorado potato beetle occurs, and what chemicals should be used, is outlined here.
  8. Plants such as pyrethrum, tagetes, onions, and garlic can be planted near viburnum. Thanks to them, it is possible to repel some types of insects.

The most effective methods of controlling black aphids

When black aphids are detected on viburnum, the first step is to eliminate the possible wintering site of these pests, and only then begin to treat the plant with various compounds. So, if you notice at least a few individuals on a bush, immediately cut out and destroy the growth located at the root. This will prevent the aphids from laying their eggs, since that is where they prefer to hide them. After this, you can begin to combat the pest directly. Let's look at the most effective ways.

Viburnum leaf beetle Description

The beetle is quite large in size (up to 7 mm), the back is painted brown. A clutch of eggs (about 20 pieces) is hidden in the young shoots of viburnum.

viburnum leaf beetle photo

At the end of spring, larvae hatch from yellowish eggs and begin to feed on the tender pulp of the leaves. Often their life activity is so active and aggressive towards the plant that only “skeletons” remain of the leaves.

viburnum leaf beetle larvae

At the beginning of summer, the larvae of the leaf beetle pest mature for further pupation, and take refuge underground to turn into young beetles. Now, in a new guise, they again head to the viburnum, but this time not to eat the pulp of the leaves, but to gnaw holes in them.

The most favorable conditions for mass reproduction of the leaf beetle are cold, damp and rainy weather. In this case, the number of pests may increase so much that the damage from them will be colossal: instead of leaves, only eaten cuttings and large veins remain on the viburnum.

viburnum leaf beetle

The beetle is dangerous because after it has dealt with the foliage, it moves on to the berry inflorescences, which threatens the complete destruction of the crop and the plant itself. In this case, the damaged bush stops growing and will not bloom the next year. In mid-summer, it is time for female leaf beetles to lay eggs, which they hide under the bark.

Viburnum leaf beetle

It is one of the main plant pests, reaching a length of about 7 mm. Every year, one individual lays up to twenty eggs on the stems of viburnum, from which by the end of spring larvae form, which eat the leaves of the plant at a high speed.

Without killing these insects, by early summer they will turn into beetles, continuing to gnaw holes in the leaves of the tree.
