For such plants as honeysuckle is characterized by high resistance to various kinds of diseases and pests. For this reason, this plant is in particular esteem among many gardeners. However, sometimes the parasites still manage to attack the fruit shrub and significantly reduce its yield. And today we will talk about how to deal with the shield on the honeysuckle.
Shchitovkami called small pests of the family of even-winged insects, the body of which is covered with a kind of armor or shield. Hence the name - shield. These parasites are attached to the bark, stems and leaf plates of plants and feed on juices.
Generic dimorphism is pronounced in the scale insects - differences in the structure of the body in females and males. The first are larger, but without wings and walking limbs. Females stick to the host plant and remain motionless throughout their life. Males have one pair of wings and developed legs.
Scarab larvae, regardless of gender, are mobile. They have no armor. As they grow older, females form a shield. They stick to the stems and leaves, and then lose the opportunity to move.
Types of scarab that affect honeysuckle
On honeysuckle can be found the following types of scutes:
- Parthenolecaniiim corni Bouche (acacia) - representatives of this species are polyphagous and can damage about 150 varieties and species of plants. With the arrival of spring, when the air temperature warms up to +9. 10 ° C larvae settle on young shoots, branches and leaves and begin to suck nutritious juices out of them.
- Lepidosaphes ulmi L. (Apple tree) is also a multifariate pest parasitizing 30 species of plants. As a result of infection, the trunk and branches become covered with brown spots and gradually dry out. If there are many insects, their activity may lead to the death of the plant. They can be recognized by an elongated body, which will be bent in the form of a comma.
On a note! The apple tree worm is most common in gardens where many trees grow!
Apple tree worm
Among the scale insects that feed on honeysuckle, most breed by laying eggs, but there are also viviparous. Motionless individuals can be found on the underside of the leaves, as well as in those places where the cuttings are attached to the branch. Settlement of young larvae occurs, as a rule, in spring. With a large cluster of parasites are so crowded that they can be taken for a raid that stretches along the large veins on the foliage.
The defeat of the shield will be represented by the following picture:
- affected plants are stunted in growth and development,
- leaves lose luster and become covered with a sticky substance,
- over time, they turn yellow, brown spots form on them, and the leaves fall prematurely,
- if shchitovki get to the fruit, they appear yellowish or brown spots.
In addition, the sticky pad released by the shield is the ideal breeding ground for black fungus, the appearance of which only aggravates the situation.If rounded, whitish or brown flakes that are difficult to separate mechanically are found on the leaves, branches or trunk - these are adult scale insects.
Methods of struggle
Since the body of the shield insects is covered with a dense shell, the fight against them is rather difficult. And before resorting to the help of special preparations, it is necessary to try to remove as many individuals as possible from the plant. To do this, make the following solution: 30 ml of liquid soap and 20 ml of denatured alcohol are added to two liters of warm water. The resulting tool is applied to the affected plant parts.
Important! However, some varieties of honeysuckle may be sensitive to the alcohol component. Therefore, they are processed only after a small test (on one sheet). If a burn appears, then the preparation should be applied only on the insects themselves!
If there are a lot of flail on honeysuckle, then it is recommended to use such chemicals to combat them:
- "Admiral" is a hormonal drug of contact-intestinal action, based on pyriproxifene. To combat the shields on the honeysuckle, 6 ml of the product are diluted in a bucket (10 l) of water, followed by spraying.
- Aktara is an insecticide with intestinal-contact activity, the main active ingredient of which is thiamethoxam. For spraying honeysuckle it is necessary to prepare a solution: 8 g of the drug is added to 10 liters of water. For every 100 m 2 about 2 liters of working solution will be consumed.
- “Actellic” is an organophosphate insecticoacaricide with contact and intestinal effects. Based on pyrimiphos-methyl, a substance from the group of organophosphorus compounds. Toxic. For processing plants, it is necessary to make a solution: for 2 liters of water 4 ml of the product.
- Applaud is an insecticidal drug that is an inhibitor of chitinous coat synthesis. Based on buprofesin. In order to use it in the fight with shinlets on honeysuckle, 10 g of concentrate should be diluted in a bucket of water.
- “Bankol” - Bensultap acts as an active substance. To prepare a working solution for 10 liters of water, 50-70 g of the preparation is added, after which infected plants are sprayed.
- "Biotlin" is a systemic insecticide based on imidaclopride. Treatment of honeysuckle bushes affected by shields is carried out with a solution: 10 ml of the preparation per water bucket.
- “Konfidor Extra” - by its properties and composition is similar to the above described remedy. Apply as follows: 1 g of the drug is added to a bucket of water. With a strong infection, the concentration is doubled.
If there are a lot of scarab honeysuckle bushes, then one treatment will not be enough. Spraying should be done two or three times at weekly intervals. At the same time, remember that with each subsequent treatment it is better to use an insecticide from another chemical group - so the parasites will not have time to develop immunity to active substances.
Why does honeysuckle dry during ramulariasis?
Sometimes the drying out of first separate sections of the leaves, and then of the whole foliage, is a consequence of the activity of the fungi belonging to the Ramularia family. Visually, such traces on the foliage of the affected plant look like patches of yellow-brown or brown with a dark rim.
The shape of the spots can be both round and irregular. And over time, they grow, and the area affected by a honeysuckle disease, like Ramulariosis or spotting, expands. Ripe spores in the form of white powder several times during the growing season are showered from the places where the fungus accumulates and spread on the basal litter and healthy leaves. See the honeysuckle capricole photo.
The danger of the disease is not only in the fact that the crown of honeysuckle dries out and the plant weakens, but also in the ability of the spores to hibernate in the middle zone and settle again in spring. Therefore, as security measures:
- gently remove the affected shoots,
- collect fallen old foliage,
- all the fungus infected parts of the plant are burned.
Treatment of bushes with fungicides, as well as with copper sulphate, Bordeaux liquid or other preparations containing copper, will help protect the plant from honeysuckle disease of edible fungal origin.
Cercosporosis - a dangerous disease of honeysuckle
The answer to the question: “Why does the honeysuckle dry?” Is often the detection of spots on the leaves, first having a dirty green tint, and then finding a brown or light gray color and a dark border around the edge. This is an obvious sign of the presence of Cercospora libicola fungi on the plant, causing cercosporosis, which is dangerous for honeysuckle edible disease.
On healthy plants, fungal spores in the form of dark powder fall from the affected litter or already infected bushes.
Measures to combat chalcosporosis are:
- in the collection and burning of fallen leaves already infected with the fungus,
- pruning shrubs in order to prevent them from excessive thickness and better ventilation of the crown,
- regular plant fertilization with mineral fertilizers,
- spraying before the opening of the buds and after picking the berries of planting and between the rows of Bordeaux liquid, cuprozan and fungicides.
Tuberculosis, or shrinking branches
Already in June, darkening becomes noticeable, and then withering and drying of the foliage and individual shoots. Why does honeysuckle dry in this case? Guilty mushrooms that have settled on a fruit bearing shrub are causative agents of tuberculosis. Shoots affected by this disease of honeysuckle can be recognized by the characteristic red-brown hillocks, within which spores mature, spreading to healthy branches and hibernating inside the shoots and fallen sick leaves.
To prevent the disease:
Mealy dew honeysuckle
The fungi that cause this disease of edible honeysuckle form a white cobweb-like plaque on the shoots, upper and lower leaf surfaces. The young branches are the first to suffer, but over time the disease spreads to the whole plant. The leaves turn brown, dry and fall early, similar processes take place on the shoots, where the bark first dries, and then the branches themselves become deformed, the plant withers and weakens noticeably.
It is possible to cope with the fungus that wintering on the bark and thicker plant residues, if the destroyed foliage and diseased branches are destroyed, and also with the first signs of honeysuckle disease, the bushes are treated with sulfur-containing preparations.
Blackening foliage and drying branches
If black shoots appear on the shoots and leaves of honeysuckle, which, without due attention from the gardener, rapidly expand and merge, then in this case it is also possible to talk about the activity of fungi. As a result, at first the foliage looks “dirty”, then it begins to dry and falls, and the berries can also affect the vital activity of the causative agent of the honeysuckle disease.
You can cope with the problem:
- timely cutting off dry and damaged shoots,
- collecting and destroying the affected foliage,
- in early spring, annually sprinkling the plants annually with aha-peak or Bordeaux mixture and repeating the treatment after flowering.
Some types of soil nematodes can spread the honeysuckle leaves mottling, expressed in changes in the natural color of the foliage, the appearance of whitish strokes and stains on the leaf plates.
As a rule, treatment with chemicals in front of this honeysuckle disease is powerless, therefore, the affected shoots and individual plants are simply removed.
Rezu Mosaic Virus
The disease caused by a virus and spread by nematodes is manifested in the fact that the newly established honeysuckle seedlings sharply shorten the internodes, and the uncontrolled growth of lateral shoots from the axillary buds begins. Foliage does not develop, plants wither and die.
Measures to combat this disease of honeysuckle include careful selection of planting material, as well as the mandatory destruction of shrubs with signs of disease.
If in winter the shoots of honeysuckle were damaged by frost, they must be cut out in time, otherwise all the same mushrooms will quickly settle and develop on the wound surface, causing the shoots to dry and leaves to fall.
Common pests of honeysuckle: photo and description
Rosana moth - This is a small, strongly pubescent brown butterfly, the caterpillars of which eat up young foliage located on actively growing shoots. Sometimes from the pests of honeysuckle, in the photo, growing points suffer, and the damaged parts of the shrub are combined into a dense, web-covered lump.
Honeysuckle Fingeror rather, the caterpillar of this brownish or gray butterfly, penetrating deep into the ovary, eats not only the pulp, but also the seeds. This leads to premature staining of fruits in blue color and their fall, which, with an abundance of pests, can seriously reduce the yield of plants.
Honeysuckle aphid - the most frequent, but always unwelcome guest on the honeysuckle bush. During the season, at least two generations of this pest of honeysuckle may appear, the photo of which well reflects the mass character of the lesion.
Harm done by adult aphids and their larvae is expressed in the weakening of the shrubs due to sucking the juices from the foliage and young shoots.
One of the most effective ways to combat aphids is the treatment of honeysuckle infusion of tobacco dust with the addition of ryl solution at the rate of 100 grams per 10 liters of water. The fluid layer should cover all foliage and shoots affected by pests. To do this, spraying is carried out in dry weather and the shrub is treated from all sides.
Gooseberry moth - It is a motley large butterfly laying eggs in the middle of summer, of which soon emerge feeding on leaves and young shoots of a caterpillar.
Willow and Acacia scale - These are pests of honeysuckle, as in the photo attached to the shoots and sucking from them juices. As a result, the plant is very weak. Fruiting fades, and after a while the bush dies.
Sometimes on the leaves of honeysuckle can be seen winding stripes with a dried and pale surface. This is the result of the activity of the larvae that develop from eggs laid in the thickness of the leaf plate by various types of fly-miners.
Making twisting passages in the foliage and feeding on the sap of the plant, as in the photo, the pest of honeysuckle interferes with the process of photosynthesis and slows the growth of the shrub.
Treatment of honeysuckle bushes with insecticide chemicals should be carried out in the form of a small-drop irrigation and only in dry weather. A day or two after spraying, the effectiveness of the procedure is checked and, if necessary, repeated processing is carried out.
In this case, we must not forget that the spring use of chemicals for edible honeysuckle is unacceptable, otherwise you cannot avoid getting toxic drugs on the ovary. In the autumn, branches and leaves, including those that have fallen, must be cut and destroyed.
Honeysuckle aphid is the most frequent guest on the bush. In one season more than two generations of this pest may appear on the honeysuckle.
If the leaves on the young shoots turn yellow, fold and fold in half, and the shoots stop growing, this may indicate the appearance of aphids on the honeysuckle. In early spring, to destroy the overwintering eggs of aphids, you need to spray the bush "Konfidorom", "Rotor" or "Aktellikom", or use the drug "Eleksar".
To combat aphids on honeysuckle, you can also use folk remedies: for example, tinctures made from garlic, tobacco and pepper.
Harm from the honeysuckle
Honeysuckle Finger - A small gray butterfly, the caterpillar of which is a dangerous pest of the plant. It takes root deep into the fruit and feeds on seeds and berry pulp. Unripe fruits darken, frown, and fall off. The yield of the plant is greatly reduced. To combat the caterpillar, the honeysquitoe is used chlorophos. To destroy the larvae used infusions of tops of potato and tomato, as well as the drug "Inta-Vir."
Rosana moth - a small brown butterfly that lays eggs in the bark of honeysuckle for wintering. The green caterpillars of these butterflies live in twisted leaves and feed on the vegetative organs of the culture: shoots, fruits, leaves and buds. Damaged parts of the bush are connected in one, covered with cobwebs. To combat the rosian moth, they use Actellic, Eleasar. You can also use a folk remedy - pine infusion.
It can be prepared at home, or you can buy coniferous extract at a pharmacy, dilute it with water and spray the shrub once a week until the pests disappear completely.
How to deal with gooseberry moth
Gooseberry moth - bright big butterfly, which in summer lays eggs on honeysuckle. After some time, the caterpillars develop from them and feed on the foliage of the shrub, eating it to the very vein. To prevent the appearance of the moth, fallen leaves under a bush need to be cleaned, the soil loosened and dug up in the fall. For prophylaxis use "Karbofos", "Aktellik".
Honeysuckle should be treated twice: when buds are blooming, until they have separated themselves after flowering.
Willow and acacia scale on honeysuckle
Some of the dangerous pests of honeysuckle are willow and acacia scale. They appear from the larvae in early spring. These small pests, covered with a shield, attach to the bark of the honeysuckle and feed on the sap of its branches and young shoots. The shrub becomes weak and ceases to bear fruit. After some time the honeysuckle bush dies. For the prevention of willow and acacia flaps, honeysuckle is treated twice in the summer (with an interval of 15 days), using the Rogor or Actellic for this.
From these pests of honeysuckle and to combat them you can use folk remedy: shrub need to pour kerosene. Делают это в холодное время года, причем температура воздуха не должна быть ниже 0 градусов.
Яблоневая запятовидная щитовкаВнешний вид у запятовидной щитовки напоминает перевернутую запятую, цветом в тон коры кустарника.
Самка в августе откладывает яйца и погибает. Fertilized eggs hibernate under its shield and in early June, oval-shaped, yellow-colored larvae appear from them.
They are located on young branches and suck the juice out of them. After a few months, they become stationary, covered with a flap. The bark of honeysuckle dies, leaves fall. Bush loses frost resistance.
To get rid of the comma-like flap on the honeysuckle, you need to know how to deal with it and what preventive measures to apply:
- before planting shrubs saplings need to be well inspected,
- when a pest is found, the affected branches are immediately cut off,
- if there are few flakes, they can be washed off with water with the addition of garlic and tobacco,
- autumn honeysuckle need to be processed using a solution of copper sulphate,
- to destroy the eggs, you need to know what to process the honeysuckle in the spring (for example, they often use the DNOC or Nitrafen solution),
- after flowering, in the period of hatching and movement of the larvae, the shrub should be sprayed with a solution of "Karbofos", "Kinmiksa" or other insecticides.
Caustic wood: control measures
Corrosive wood - Gray moth, which is one of the main plant pests. She lays eggs in the middle of summer at the base of the honeysuckle branches. A caterpillar emerges from the eggs, which is embedded in the shoots and makes passages in them, throwing out the excrement-sawdust. The branches, in which she visited, dry up, and the caterpillar itself remains to winter in the deep layers of wood.
To combat coronary woods use gasoline. It is necessary to roll balls of cotton wool the size of a pea, put them in a container with gasoline and well soak. Petrol balls are introduced into the caterpillar turns using wire.
Moth-baby is a small butterfly that lays eggs on the leaves of honeysuckle. From eggs appear amber-yellow with brown-red-headed caterpillars. They cause serious harm in September, feeding inside the leaf and leaving on its top double-sided mines with a narrow line of excrement. To fight with moth-baby you need to spray honeysuckle "Aktellik", "Fitoverm" or "Karbofos". You need to process at the end of summer - early autumn, when butterflies lay eggs.
General preventive measures to prevent the occurrence of pests on honeysuckle include constant thinning of the planting, cleaning of dry leaves under the bush and regular inspection of the shrub.
The most common diseases of edible honeysuckle and their treatment
Honeysuckle foliage spotting is a symptom of the defeat of a shrub with parasitic fungi or viruses. The leaves change their shape, they gradually dry out. The following are now distributed fungal diseases honeysuckle:
- this shrub can affect such a disease as moniliosis. With this disease on the branches of the shrub foliage dries out, but it does not crumble from the branches. The fungus enters the branches through the cracks and spreads throughout the shrub. Having noticed the first signs of this disease, the diseased shoots should be cut so as to capture a small portion of healthy wood. After trimming, the cut point should be treated with preparations containing copper. For the prevention of monilial burn, the stems should be treated with Fitolavin solution before the buds swell and in late autumn,
- Honeysuckle can also be affected by powdery mildew. To combat this disease, you can use tobacco dust, diluted in water, copper sulphate with soap (a glass of copper sulphate is diluted in a bucket of water), a solution of wood ash or bio-soda,
- dark green spots appearing on the foliage of honeysuckle indicate the onset of cercosmos at the plant. Subsequently, the spots may grow brown or lighten, and a dark rim appears at the edges. To avoid the onset of this disease, it is necessary to thin out the shoots. The main method of dealing with the disease - cut and destroy the affected foliage. Twice a season — before the buds swell in the spring and at the end of June after picking the fruits — the bushes are sprayed with preparations containing copper. Or modern antibiotic of a natural origin Fitolavin - in the early spring and late fall,
- when the shoots begin to dry, it means that the honeysuckle struck tuberculosis. Red-brown hillocks appear on the branches, in which the spores of the fungus-causative agents of this disease develop. Infected branches are cut and burned. There is no other way to deal with this disease. For the purpose of prophylaxis in the spring, before blooming buds, the shrub is treated with copper sulphate or Fitolavin,
- black fungus on honeysuckle, as well as on currants, appears when sweet secretions appear on the leaves - honeydew. This may be caused by damage to nearby fruit trees by pests such as the cicadka, the hedgehog, and the honeysuckle itself. To protect against the fungus, it is necessary to eliminate the cause - the selection of the pad, to treat the garden with insecticides,
- foliage also changes shape and flies if rust attacks on the honeysuckle. Only this disease affects both the foliage and the stems. Rust fungus parasites on plants of many families, forming in the cycle of its development different types of spores: some live and parasitize on one host, others change their breadwinner. Planriz, Gamar (bactericide), Gaupsin, Fitosporin-M are used to protect against rust.
Please note that before the main measure of treatment and prevention of fungal diseases was the spraying of stems and leaves of honeysuckle with copper sulphate or Bordeaux mixture. But from the frequent use of copper-containing drugs, the fungi have mutated, so now in natural farming the emphasis is on the use of biostimulants, natural antibiotics and EM drugs. Very much helps out a mixture of biofungicides (Gamar, Alirin, Planriz) in the so-called tank mixtures.
Of viral diseases until the Reza mosaic virus is found with a characteristic yellow-white mosaic on a sheet. There are still no methods for treating such diseases, so the bush will have to be dug out and burned, and not honeysuckle plants should be planted in this place for 5 years.
Honeysuckle pests edible
In late spring, the foliage of honeysuckle may be stained with yellow. Such damage to the foliage can be caused by various diseases as well as “harmful” bugs. Main pestsaffecting this berry shrub are as follows:
- aphids are honeysuckle cereals at the end of spring on young leaves of honeysuckle, and at the beginning of summer they migrate to cereals. By September, the aphid returns to the honeysuckle bushes, where it lays eggs. They will winter on the plant all winter. So aphid lives and breeds from year to year. Fighting aphids includes bioinsecticide treatment (tobacco garlic brewing, Fitoverm). Also should be spread out under the bushes of elder twigs,
- the honeysuckle mite prefers to live among thick overgrowth or in the shade. Mite sucks the juice of the foliage, then the leaves curl and fall. In the process of dealing with mites, thin the shoots and treat the shrubs with insecticides,
- Molecule and honeysuckle miner are very dangerous pests for honeysuckle. They penetrate into the bark of the shoots of the bush and feed on the sap of the branches. To destroy these “harmful” bugs, shrubs are treated with insecticidal biological preparations, planted repellent plants,
- if the leaves become speckled, this may be due to the vital activity of some species of nematode in the soil. Damaged leaves should be cut and burned,
- chopping the leaves, and then drying up the branches causes the gnawing of the beetle beetle larvae. The signs of damage and the behavior of the pest are somewhat reminiscent of a glass case on a currant. These branches are cut at the base and burned. Bioinsecticide treatment is useless - the larva is inside the branches and is inaccessible to the preparations. But the scaring plants near you can plant,
- honeysuckle shoots still strikes shchitovka. On the honeysuckle can wield 2 types of pest - Apple tree or willow scale. Larvae hatch in spring and, clinging to the shoots, are covered with a dense shield. Sucking the juice from the plant, they cause significant damage to the branches of honeysuckle, which leads to drying and death of the bush. It is better to cut and burn the affected branches, and to treat the bush several times with Flyoverm,
- when the fruits and seeds of honeysuckle become sluggish and shriveled, this indicates the defeat of their honeysuckle finger horn. Since during the emergence and ripening of the fruit can not be used chemicals for spraying honeysuckle, then to combat this pest should use an infusion of shoots of potatoes and tomatoes.
It is necessary to fight pests and diseases of honeysuckle immediately, as soon as gardeners notice the first symptoms of a shrub lesion. The sooner you start plant protection, the faster the honeysuckle will "recover"!
