Pests and diseases of honeysuckle and the fight against them is a hot topic for gardeners involved in the cultivation of this beautiful and unpretentious shrub. It is possible to save honeysuckle from damage by ailments and insects, subject to careful care and control over the development of the plant.

Honeysuckle diseases: description with photos and treatment methods

Honeysuckle is considered a rather unpretentious plant, rarely suffering from fungal ailments. However, diseases still affect the shrub, the cause is most often improper care or difficult climatic conditions. To keep honeysuckle healthy, you need to know the symptoms of the most common diseases and be able to cope with them.

How to deal with powdery mildew on honeysuckle

The fungal disease powdery mildew is easy to recognize by the appearance of a white "fluffy" bloom on the underside of the leaves. With an advanced course of the disease, plaque appears on both sides of the leaf plates. Gradually, dark spots form in places of plaque, the leaves of honeysuckle turn brown and begin to dry, the branches are deformed and bent. The disease can lead to a complete premature fall of foliage, as a result of which the shrub will cease to bear fruit and become less resistant to frost.

Powdery mildew is easy to recognize by a whitish bloom.

Treatment of the disease is carried out with drugs Tiovit, Chistotsvet and other fungicides. It is recommended to spray the plant twice or three times in the spring, before and after flowering.

Important! Spores of the fungus that causes powdery mildew overwinter in plant debris in the trunk circle and in cracks in the bark. Therefore, to prevent the disease, it is necessary to carry out sanitary pruning annually and remove all plant residues from the site.

How to treat cercosporosis on honeysuckle

Cercosporosis is a fungal disease, due to which round dots with a reddish-brown border around the edges appear on the foliage of the honeysuckle. Cercosporosis leads to gradual drying of the leaves, with black fungal spores appearing in the middle of the dark spots.

Cercosporosis manifests itself as brown spots with a reddish border.

To cure the disease of the leaves of honeysuckle, it is necessary to treat it with Fundazole or copper sulfate. Spraying is carried out in early spring, and then repeated twice more shortly before and after flowering. All shoots affected by the disease must be removed so that the spores of the fungus do not spread to healthy areas.

Rust treatment on honeysuckle

In the middle of summer, the shrub is often affected by rust, a disease that causes red-orange spots on the foliage. Rust spreads especially quickly in high humidity conditions. Honeysuckle changes its color, the processes of photosynthesis in the plant are disrupted, and premature leaf fall occurs.

The appearance of rust is evidenced by the browning of the leaves.

If rust appears on the shrub, it is necessary to immediately remove the affected parts and treat the plant with Bordeaux liquid. It is also recommended to inspect the area where the shrub grows, and remove cereals or barberries from it, if they grow nearby, they are the main carriers of rust.

Honeysuckle leaf mottling treatment

Viral mottle is a disease of honeysuckle, which is provoked by nematode pests. The symptoms of mottling are spots and dots on the foliage of a shrub, usually they have an uneven arched shape. Mottling causes serious harm to the health of the shrub, honeysuckle begins to dry and sheds leaves, its endurance and fruiting volumes decrease.

Mottling is manifested by uneven spots on the foliage.

Mottling can be cured by treatment with fungicides, for example, Fundazol, copper sulfate, Bordeaux liquid. All affected shoots must be completely cut off. It will no longer be possible to restore their health, but the fungus from them can spread to healthy leaves.

Common cancer

A very dangerous disease for honeysuckle is an ordinary cancer that affects the bark on the trunk and shoots of the plant. Cancer manifests itself as deep wounds on the body of the bush, ulcers have infusions along the edges, which sometimes grow together and form cracks. As the honeysuckle grows, the cracks in its bark widen, and gradually deeper ulcers form, from which the wood of the trunk and shoots dries out.

Common cancer affects the trunk of the plant and leaves ulcers on it.

Symptoms of ordinary cancer usually appear in the summer, the disease spreads rather quickly to neighboring parts. In order to prevent the death of the shrub, you must immediately cut off all branches affected by cancer. Healthy parts of the plant are treated with Bordeaux liquid, the cuts on the tree trunk are covered with oil paint or sprayed with copper sulfate.


Ramulariasis is another ailment that poses an increased danger to honeysuckle. You can recognize the disease by gray-brown spots of irregular shape with a dark border, they appear in the spring on young leaves of a bush. As the plant develops, the spots grow in size; in cloudy rainy weather, they can be covered with a white bloom.

Ramulariasis is an ailment that leaves spots on the leaves of a bush

With the defeat of ramulariosis, the foliage of the bush cannot develop normally and dies off. As the plant has to devote resources to the formation of new leaves, this weakens the honeysuckle and impairs its health.

If honeysuckle is sick, then the treatment of ramulariasis is carried out using popular fungicides - Fundazole or copper sulfate. The first spraying must be carried out in the spring when the temperature is set to about 15 ° C, it is during this period that the spores of the fungus begin to actively develop. To achieve the best effect, it is recommended to carry out the treatment 2 or 3 more times per season.

Razuha Mosaic

Razuha mosaic is a viral disease of decorative honeysuckle that occurs on a bush under the influence of the vital activity of nematode worms. The main symptoms of the disease are a decrease in internodes on honeysuckle and the appearance of numerous lateral shoots. Although at first glance the shrub is actively developing, its shoots become weaker and thinner, the leaves decrease in size and begin to dry out over time.

Razuh mosaic leads to unhealthy overgrowth of bush

Attention! The rezuha mosaic is extremely difficult to treat, therefore, usually when a viral disease appears, the infected bush is simply removed from the site and burned. This helps prevent infestation of other shrubs.


Drying of the shoots of honeysuckle, or tuberculariosis, is characterized by the appearance of numerous red tubercles with fungal spores on the shoots of the bush. Already at the beginning of summer, honeysuckle, affected by tuberculariosis, withers and sheds its leaves, which negatively affects the fruiting and endurance of the plant as a whole. The development of the disease occurs cyclically, at the end of summer, red tubercles with spores are again formed on the shoots, and the infection of the shrub is repeated anew.

With tuberculariosis, small reddish growths appear on the shoots of the plant

Measures to combat the disease are very simple - all diseased branches must be cut and burned. Places of cuts and healthy parts of the plant are treated with Bordeaux liquid and copper oxychloride in order to prevent a new round of the disease.

Honeysuckle frostbite

Honeysuckle is moderately frost-resistant and often suffers from recurrent frosts in the spring. Sharp cold snaps during the active growing season lead to the fact that the bark of the bush cracks and bursts, wounds remain on the trunk and shoots, in which a saprotrophic fungus settles. As a result, a dark bloom forms on the surface of the wounds, negative processes begin, and the shoots of the plant dry up and die off.

Cracks on the trunk of a bush are called frostbites.

It is very difficult to completely prevent diseases of the honeysuckle trunk. If frost holes appeared after spring frosts, then it is recommended to remove the affected branches completely. If the shrub is seriously injured, and it is impossible to carry out a full-fledged sanitary pruning, then the frost holes must be treated with Bordeaux liquid after flowering.

Honeysuckle pests and control

For honeysuckle, not only fungal ailments are dangerous, but also harmful insects. Pests that have settled on the leaves and branches of a bush can seriously disrupt its vital processes and lead to a weakening of the plant.

How to treat honeysuckle from aphids

The honeysuckle aphid is a dangerous pest that can kill a shrub in a short time. Usually, 2 types of aphids can be observed on honeysuckle:

  • apical - the insect affects the tops of the shoots, the leaves curl and the growth of the plant stops;
  • green - this aphid spreads evenly throughout the shrub and feeds on leaf juices.

Symptoms of spring honeysuckle pests are yellowing and curling of leaves. On closer examination, small green or grayish insects can be seen on the leaf plates. Aphids usually appear in early summer, the second wave of infection occurs in early July.

Aphids, with a strong spread, can destroy all the green mass

The fight against the pest is carried out with the help of insecticidal preparations - Aktara, Rogor and others. It is best to prophylactically treat the shrub in early spring, before the buds appear, in order to eliminate the larvae of the pest. Summer treatment for aphids brings low results; it is quite difficult to eliminate insects with massive infestation.

How to process honeysuckle from scale insects

Scabbards of various species are a common pest of most berry bushes. They also affect honeysuckle, usually infection occurs in the spring with the arrival of heat, when the larvae of the pest wake up.

The adult scale insect is a small insect with a hard carapace, hence the name. Pests settle mainly on the lower surface of foliage and at the places where cuttings attach to branches. Since the scabbard draws vital juices from leaves and shoots, honeysuckle under its influence quickly weakens and begins to lose its green mass.

The scabbard draws juices from the shoots and leads to the death of the bush

You need to fight the scabbard with the help of Actellik or Rogor insecticides. Processing is carried out in the middle of summer, you need to spray the bush twice with a break of 14 days. Also, spring preventive spraying of the bush will not harm, it will allow you to cope with the pest even at the larval stage.

Honeysuckle mite

If honeysuckle grows in the shade and with high humidity, then the shrub often infects the honeysuckle mite. You can recognize this pest by the uneven spots on the lower surface of the leaves and by the browning of the foliage closer to August. Infection with a honeysuckle mite leads to the fact that at first the edges of the leaf plates are deformed, a dark bloom appears on the surface of the leaves, and then the crown of the bush simply falls off.

Mite pests cause browning and shedding of foliage

You can eliminate the honeysuckle mite with the help of special solutions - Actellik, Mavrik, Tedion and others. The first spraying should be carried out in June, then the honeysuckle should be treated twice more before the end of the growing season.

Advice! The thickened crown of the plant contributes to the reproduction of the honeysuckle mite. Therefore, in order to avoid infection, the shrub should be regularly trimmed and thinned.

Honeysuckle fingerfly

The development of the honeysuckle bush in the garden is harmed by fingerwing - a small gray butterfly, the caterpillars of which feed on the fruits of the plant and even its bones. The honeysuckle fingerfly does damage mainly to the crop, the fruits, due to its effect, darken, shrink, do not ripen to the end and crumble to the ground.

Fingerwing pest eats developing honeysuckle fruits

Honeysuckle fingerwing can be removed with the help of Inta-Vir solution, which is safe for ripening ovaries, and with the help of homemade tinctures on the tops of potatoes and tomatoes. Aggressive insecticidal preparations for saving honeysuckle fruits are not recommended. The crop after such spraying will become unusable, and in any case, you will have to say goodbye to it.

Rose leaf roll

The leafworm is a small brown butterfly that lays eggs on the bark and leaves of honeysuckle. The caterpillars hatched from the eggs feed on the juices of foliage, buds and shoots, in the process of their vital activity, wrapping up the damaged areas of the bush in a light cobweb. If left unchecked, it can seriously damage the honeysuckle and destroy the green parts of the shrub.

Rose leaf roll is able to destroy the green mass of honeysuckle bushes

Insecticides Actellik and Elesar help well against the leafworm pest. It is recommended to process plantings several times per season. The first spraying should be carried out in late April or early May in order to immediately eliminate most of the awakened larvae.

How to treat honeysuckle from pests and diseases in spring

Different pests and fungal diseases of honeysuckle manifest themselves at different times. Some illnesses begin to develop with warmth, while others do not show symptoms until mid to late summer.

To protect honeysuckle from pests and diseases, it is customary to carry out annual preventive treatment. It is carried out in the spring, at a time when stable temperatures above 5 ° C have been established, but the buds have not yet begun to bloom. Usually, several sprays are carried out during the spring and summer, this allows you to eliminate the larvae of most pests and fungal spores:

  1. Spraying honeysuckle is allowed with any garden insecticides and fungicides. The most well-proven means such as Actellic, Fundazol, Bordeaux liquid and copper sulfate, Aktara and others.
  2. If honeysuckle is slightly infested with pests, you can also use home remedies, for example, ordinary soap solution.
  3. It should be borne in mind that with a neglected defeat, folk remedies may not bring results.

After the first preventive spraying in early spring, it is recommended to repeat the procedure 2 or 3 more times to achieve maximum results. It should be borne in mind that it is impossible to spray honeysuckle directly during flowering, chemical preparations can disrupt the pollination process.

You can spray the bushes not only with chemicals, but also with boiling water.

Some gardeners also process honeysuckle in spring with boiling water. It is performed immediately after the snow melts, and before bud break, the roots of the bush are covered with dense material, and the ground part of the bush is poured with hot water. This treatment eliminates most of the larvae and fungal spores in the bark.

To protect honeysuckle from ailments and pests, it is important to carefully monitor the sanitary state of the garden. Every spring, the honeysuckle shrub is inspected for damage and dry, broken, twisted branches are promptly removed. With a thickened bush and the presence of diseased shoots, the likelihood of developing fungal ailments greatly increases.

Important! Every fall, you must thoroughly clean the garden and completely remove all fallen leaves, broken branches and other plant debris from the ground. Insect larvae and fungal spores hibernate in plant debris in the near-stem circle.


Pests and diseases of honeysuckle and the fight against them is a topic that should be familiar to every gardener. Regular examinations of the shrub, as well as spring preventive treatment, can protect the honeysuckle from damage and prevent the development of diseases.
