Raspberries of any variety can be attacked to a greater or lesser extent by pests. The consequences of damage often lead to a sharp decrease in the commercial quality of fruits and berries, a significant shortage and even complete destruction of the crop. In order to successfully fight pests, you need to know a lot: how they look, what harm they cause, at what time they can be dangerous, under what conditions they appear, and much more. The correct methods of plant protection allow you to avoid plant damage and preserve the harvest

What are the pests of raspberries?

There are quite a few varieties of raspberry pests. They can affect various vegetative organs of plants at different stages of their development. To prevent harmful insects from catching the gardener by surprise, it is better to get to know them in advance.

Raspberry stem (shoot) gall midge

The pest damages raspberries and blackberries. Small mosquito (1.6-2.2 mm) that flies in May-July during raspberry flowering. The female lays eggs on shoots, from which larvae appear in 8-10 days. They crawl under the bark of the stems and feed on their sap. At the site of the introduction of the larvae, swellings (galls) are formed, in which the larvae remain to winter. Gauls are 3 cm long and 2 cm wide. Cracks form on the bulges, the bark begins to flake off, the shoot collapses and easily breaks off at the site of damage.

Raspberry shoot gall midge is a small mosquito, its larvae penetrate the raspberry stem and form swellings (galls) that reach 3 cm in length 2 cm in width

In the spring in each gall there can be from two to eleven larvae, which grow up to 3-4 mm pupate. At the end of May, during the flowering period of raspberries, adults appear. The insect is very harmful, it can damage up to 70% of raspberry shoots.

Raspberry walnut

Insect 2-3 mm long with black body and stalked abdomen. Like the shoot gall midge, it damages raspberry stems. The larvae penetrate the shoot and, feeding on its tissues, cause swelling. Affected stems also break off or dry out easily. Fruiting decreases sharply. The galls formed from damage by the gall midge differ from the swellings formed when the stem gall midge is damaged, in size and can reach a length of 10 cm.

Raspberry gum is a small insect whose larvae infect raspberry stems, forming swellings that can reach 10 cm in length

Raspberry shoot aphid

The pest belongs to the order of equal-winged proboscis insects. The color of the aphid is light green with a waxy coating, the size is about 2.5 mm. It affects the ends of shoots and leaf stalks, sucking the juice out of them. Leaves curl, shoots bend, growth stops. Raspberries do not bear fruit, as the flowers stop developing and dry out. The pest causes significant damage in drought. Plants heavily affected by aphids lose their frost resistance. And also aphids are a carrier of viral diseases of raspberries.

The female aphid lays shiny black eggs on the shoots near the buds, where they hibernate. With the beginning of the growing season, larvae appear, which feed on the juice of the kidneys. Developing rapidly, without fertilization, they give birth to live larvae. Several generations develop during the season. In summer, winged aphids appear and spread to other plants.

Raspberry weevil (raspberry flower beetle)

The pest can also be called a strawberry-raspberry weevil, as it damages strawberries and strawberries in addition to raspberries. A small beetle 2.5–3 mm in size with a long thin proboscis is black (may be brown). Beetles hibernate under plant debris and clumps of earth. In spring, the pest feeds on young leaves, and before flowering lays eggs one by one in each bud and gnaws at the peduncle, which breaks and remains hanging on the film. A larva emerges from the egg, which eats up the bud and pupates in it. The weevil does a lot of damage to the crop. In the middle of summer, young beetles hatch, which feed on leaves and petioles.

Raspberry beetle

One of the most dangerous pests of raspberries. In the years of mass flight, it damages up to 30% of buds and flowers. The beetle is of a dirty gray color, densely covered with rusty-yellow or grayish hairs, which give it a dirty rust color.

For wintering, beetles penetrate into the soil to a depth of 15–20 cm. When the ground warms up to 12 ° C, they crawl out from there and begin to feed on pollen and anthers of fruit and berry crops, as well as flowering weeds. During the period of bud extension on raspberries, beetles switch to this culture. They gnaw flowers, buds, young leaves. In raspberry flowers, the pest gnaws at the nectaries and lays one egg at a time, of which worm-like larvae appear after 8-10 days. They gnaw out the stalks and bases of the berries, which become ugly and dull, shrink, wither and rot. The quality of the crop drops sharply. When picking berries, beetle larvae can often be found inside.

Raspberry stem fly

A brown insect 5–7 mm long, flying in May-June, is a raspberry stem fly, it can also be called a raspberry fly. At this time, young shoots of raspberries begin to grow. The fly lays eggs at their tops and in the axils of the leaves that are beginning to form. After about a week, larvae hatch, which immediately penetrate the middle of young stems and gnaw them, laying spiral and circular passages. The apical parts of the damaged stems gradually fade, turn black and die off after 10-15 days. Some stronger stems can give lateral shoots, but they do not have time to ripen until autumn and die in winter. In thickened raspberries, up to 80% of the stems can die.

After 12–16 days, the larvae leave the stems and penetrate into the soil to a depth of 5–6 cm, where they remain for the winter. In May, when the soil warms up at a depth of occurrence of the larvae to 12–13 ° C, they pupate. In dry and warm weather, after a week, and in rainy and cool weather, after 2-3 weeks, flies begin to fly out. In addition to raspberries, the fly also damages blackberries.

Raspberry kidney moth

A small moth with shiny purple-brown front wings covered with yellow specks. The hindwings are gray with black silvery fringes. The wingspan is 11-14 mm. Caterpillars are red with a black head, 7–9 mm long. The pest overwinters in the caterpillar stage in cocoons under the bark of raspberry stalks, in hemp or on the ground under bushes. In early spring, the caterpillars crawl out and penetrate the raspberry buds, which dry up and can give only single leaves. Gnawing a bud, the caterpillar penetrates into the middle of the shoot and pupates. A few days later, butterflies appear from the pupae, which, during the flowering period of raspberries, lay one egg in each flower. The caterpillars that emerged from the eggs feed on the fruit of the berries until they ripen, and then descend to the base of the shoots, find shelter and winter in the form of a cocoon, withstanding severe frosts. Raspberry kidney moth also damages blackberries and in some years can cause great damage.

Spider mite

An oval arthropod arachnid, grayish-green at the beginning of the season, orange-red from late summer to spring. The mites are very small - 0.25–0.43 mm. For the winter, fertilized females hide in various shelters: in plant debris or under the bark of trees. Ticks appear in the spring on the underside of young leaves, suck the juice out of them and entwine them with thick cobwebs, in which they lay eggs. The larvae develop within 1-3 weeks and during this time they suck the juice from the leaves, green shoots and fruits. Several generations of the pest are reproduced during the season. Brown spots appear on the leaves, they dry and fall off. In dry summers, plants heavily damaged by mites die. Crop losses can be up to 70%.

Raspberry glass

The butterfly is blue-black in color, with a long slender body and transparent glassy wings. Yellow rings on the abdomen give it a wasp-like appearance. The wingspan is 22–26 mm. In June-July, the glassware begins to fly and lay eggs in the soil at the base of the raspberry stems. Females are very fertile, each of them can lay up to 200 eggs. The hatched caterpillars bite into the stems and roots, grinding through numerous passages, in which they remain for the winter. The next year, they continue to grind through the passages, and then pupate, having previously prepared a hole for the butterfly to exit. Damaged shoots develop poorly, bear little fruit, become fragile in the lower part. Glass beetle is less common than gall midge, weevils and beetles. Most often it can be found in neglected plantings in personal plots.

There are two types of scoops that damage raspberries. The first is a raspberry scoop, a butterfly with a wingspan of about 33 mm. The front wings are dirty purple, the hind wings are brownish gray. Flies in June-July. The caterpillar lives in summer and autumn, damaging the leaves of raspberries, blackberries, nightshades and some other plants.

The second type is the golden raspberry scoop. A butterfly with lemon-yellow wings covered with rusty-brown spots. Along the edges of the wings there is a wavy line with dots. Lives from August to October. The caterpillar is gray-brown, damages raspberries, gooseberries and other cultivated and wild plants.

How to deal with raspberry pests

There are various methods of dealing with raspberry pests: by means of treatments with special preparations that destroy insects, agrotechnical methods, and also folk remedies. The choice of a method of struggle depends on various factors, but you should always take into account that prevention is never superfluous.

Types of pest control drugs

To control pests, raspberries, like any other cultivated plants, can be treated with biological and chemical preparations. Currently, there is a large selection of them.

It is preferable to use biological agents, since they are less toxic or completely safe for humans and do not accumulate in fruits.

The essence of the biological method of plant pest control is to use the phenomenon of superparasitism or antagonism existing in nature between microorganisms living on plants or in the soil. Natural enemies of insects and ticks are various microorganisms, among them are pathogens of bacterial, fungal and viral diseases of insects and plants.

Bioinsecticides act on groups of insect pests, and bioacaricides act on ticks. There are drugs that are effective against both insects and ticks, they are called insectoacaricides. These include Aktofit and Fitoverm. The final treatment with biologicals can be carried out shortly before harvest. Biologics have their drawbacks. Their shelf life is short; in liquid form, they can be stored from two to eight weeks. They also require special storage conditions. The frequency of treatments with biological products is higher than when using chemicals (every 7–20 days, depending on the drug), with significant lesions, they may be ineffective.

Since biological preparations are low-toxic or completely safe for humans, the last treatment can be carried out shortly before harvest.

The use of chemical insecticides (a type of pesticide designed to kill insects) is more effective, but also less safe for humans and animals. The vast majority of chemicals are highly toxic, therefore, when using them, you must strictly adhere to the dosages, terms of use and precautions indicated in the instructions. Usually, chemical drugs have a much longer waiting time than biological drugs; it can vary from 20 to 60 days depending on the drug.

When treating plants with chemicals, you must take precautions and spray the plants only at certain times (taking into account the waiting period)

How and when to treat raspberries from pests

If it is necessary to treat raspberries from pests, it is important to correctly navigate in the choice of the drug. There is a fairly large variety of them. To ensure maximum protection of plants from pests and at the same time to obtain products that are safe for health, it is better to use chemical and biological preparations in combination.

It is important to choose the right drug for pest control, do not abuse chemicals if you can get by with biological drugs

Treatments must be carried out within the recommended time frame, otherwise they may be ineffective. The calendar of treatments is compiled depending on the stage of the seasonal life cycle of the plant.

How to protect raspberries from pest damage

Timely preventive measures of an agrotechnical nature and the use of folk remedies in most cases allow avoiding the use of chemicals.

Agrotechnical methods of protection

When planting raspberries, you need to take into account that they cannot be planted after strawberries, potatoes and tomatoes due to the common pests. The best precursors for this crop are lettuce, spinach, onions, radishes, and beets.

Autumn fall plowing (digging) of raspberry rows plays an important role in pest control. During processing, weeds are destroyed. Some of the harmful larvae and pupae turn up on the surface and die from unfavorable factors, while the other part is plowed to such a depth from where they can no longer get out.

The land dug up in the autumn period freezes and chills in winter - hence the name autumn plowing.

It is recommended to apply the following agrotechnical preventive measures:

  • careful plant care;
  • weed control;
  • thinning thickened areas of raspberries;
  • timely cutting and removal of fruiting stems (immediately after the end of fruiting);
  • cleaning and burning of plant residues in raspberry plantations;
  • mulching the soil under the bushes with a thick layer (at least 8 cm) so that pests cannot climb to the surface;
  • cutting out damaged shoots of raspberries with galls (damaged by the shoot gall midge and nut-making) and burning them;
  • low cut (near the ground without leaving stumps) of fertile, as well as weak and underdeveloped stems damaged by kidney moth;
  • cutting and burning of the tops of the shoots inhabited by aphids;
  • collection and burning of damaged buds with eggs and weevil larvae;
  • systematic cutting and burning of wilting stems damaged by the raspberry fly;
  • shaking off weevils and raspberry beetles from bushes onto linen or gauze shields or nets;
  • harvesting raspberries in a container lined with linen inside, with the subsequent destruction of all the larvae of the raspberry beetle that emerged from the berries and remained at the bottom of the container;
  • catching scoops with light traps and trapping containers with odorous baits;
  • planting in rows of raspberries repelling pests of plants, such as calendula, marigolds, garlic, dill and others.

Folk remedies

The use of grandmother's recipes for raspberry pest control will be absolutely harmless. There are quite a few folk remedies, but the table shows the most popular of them.

Table: folk remedies for raspberry pest control

Obtaining high and stable yields of good quality raspberries is possible only with the systematic and systematic implementation of a set of measures to combat pests. It is necessary to learn how to correctly assess the degree of risk of infestation by pests and choose the best methods to combat them. In the event that you can get by with folk remedies, agrotechnical methods or biological preparations, you should not abuse chemicals. Timely preventive measures will allow you to get a decent harvest of environmentally friendly products.

The main diseases of raspberries - fight, treatment and prevention

Raspberries belong to the category of thorny shrubs that have powerful rhizomes and a large number of shoots. Growing a shrub in one place should be carried out no more than 7 years. Otherwise, there is a decrease in fruit size and looseness of the root system of this plant.

In this article, we will look at the main diseases of raspberries, find out why leaves can dry on a bush or berries rot and how to deal with it.

Diseases of raspberry berries and leaves: photo, description and treatment

Purple spot, or didimela. This is a fungal disease: oblong purple spots appear on green stems. It is widespread in various countries and has been known for a long time in subsequent years, the harm from it increases. It mainly affects stems and buds, the ability of the disease to affect leaf petioles, veins, twigs is noted.

Didimela symptoms are very typical, especially in the early stages.

Look at the photo of this raspberry disease - vague purple spots appear on the affected bushes below the point of attachment of the leaf petiole:

The spots grow rapidly and stand out sharply against the background of the light bark of annual Raspberry shoots. As they grow, the spots become brown-brown with a lightening middle, on which brown large tubercles - pycnidia of the fungus are scattered. The spots cause cracking and peeling of the bark, merging, ringing shoots that break and dry out. The buds on diseased bushes do not develop.

The disease spreads in August - September, when there is a mass maturation of the spores of the didimela pathogen. The development of the disease is facilitated by wet weather, abundant dew, a strong thickening of the plantings, poor sunlight and the defeat of raspberries by stem gall midge. Older shrubs are more susceptible to purple spotting.

Brown and red-stemmed raspberry varieties with smooth bark are relatively resistant to purple spotting.

Powdery mildew affects raspberries in years with high humidity, as well as in dense and shaded plantings. At the ends of the growing shoots, a white, initially tender bloom is formed, developing on the upper and lower sides of the leaves, partially capturing their petioles and the young ends of the shoot itself. In humid conditions, the plaque becomes powdery and clearly visible. In less favorable conditions, plaque is difficult to detect, since it merges with the white hairs of the raspberry itself. Raspberry leaves affected by this disease stop growing and become chlorotic.

The disease develops in the first half of summer, including the ripening period of berries. The causative agent of the disease in the winter remains in the buds of the affected shoots, partly on the fallen diseased leaves. The harmfulness of powdery mildew is expressed in the oppression of the ends of the shoots and leaves of raspberries. Under the influence of the disease, they die off or, without ripening, freeze out. The raspberry berries affected by this disease become small, with an unpleasant bluish color and a mushroom smell.

Anthracnose can manifest itself on raspberries with regular excessive watering. This is a fungal disease in which very small, rounded, at first pointlike spots, then slightly increasing spots of 1-3 mm in diameter are formed on the leaves, petioles, shoots, fruits. The spots are grayish in the middle, surrounded by a wide purple border. The spots are scattered unevenly, but are often located in the folds and along the leaf veins. Without treatment for this disease, raspberry spots merge. Affected tissue in old spots may fall out. The spots on the petioles are very small, depressed in the form of ulcers, merging.

On the stems, anthracnose begins with the formation of individual small, deep ulcers surrounded by a wide purple border. The affected part of the stem is covered with a brown, corky, cracking tissue, as a result of which they die off prematurely. Affected berries stop filling and dry up.

The causative agent of the disease hibernates mainly in the shoots, partly in the affected leaves. Most often, the disease enters new areas of raspberries with the affected planting material.

Anthracnose develops in spring, after the leaves have opened. The further course of the disease depends on the weather. The disease develops very strongly in damp years. During the ripening of the crop, anthracnose appears in mass, completely covering the fruit clusters, which prematurely die off with many unripe berries.

White spot (septoria) raspberry leaves are damaged. At the same time, medium-sized rounded spots are formed, at first pale brown, then whitening, with a persistent brown border. Over time, the whitened center of the spot collapses and falls out. With a strong development of the disease, there are a lot of spots, the tissue between them turns brown, and a significant proportion of the leaf blade dies off.

Rust. The first signs of it appear on the upper side of the leaves in the form of separate yellow-orange tubercles, then they become black powdery. In the stem form, rust affects the lower part of the stem, which is at ground level. The affected stem tissue turns brown, covered with light-colored sores. In places where the largest ulcers develop, the raspberry stem becomes flat. The next year, with continued growth of shoots, large rust ulcers crack with deep longitudinal cracks. If you do not take measures to protect raspberries from this disease, there is a complete death of the shoots. Massive leaf disease leads to their premature drying.

Verticillus wilt causes wilting of annual raspberry shoots. In this case, the lower leaves turn pale, then turn yellow, and the tissue between the leaf veins dies off. The internodes are shortened, the shoots become short, the bark cracks in the form of a gap, the roots turn brown, the tops of the shoots wither, droop, and the shoot dies off.

Gray rot raspberries may be affected in damp and cool weather. At the same time, they are covered with a gray velvety dusty coating of the fungus - the causative agent of the disease.

Pest characteristics and control options

Raspberries are a whimsical culture that requires full and competent care. In case of mistakes in agricultural technology, shrubs not only fall in yield, but also reduce immunity. Such bushes are more often attacked by numerous pests, they get sick more.

The gardener needs to carefully observe the plantings, notice the slightest changes in the growth, development, and appearance of the culture. The description with photographs will help determine who you have to fight with.

Raspberry beetle

Besides raspberries, this bug is dangerous for blackberries. The life cycle is one year, gives one generation of larvae. An adult (imago) does not exceed 4 mm in size, the color is gray-black. The entire body is covered with yellowish hairs.

Damages leaves, buds, flowers and berries of the crop. Female beetles lay eggs from spring to mid-summer. The larvae are yellowish caterpillars, feed on raspberry fruit, gnaw at the base of the berries. This leads to deformation and decay of the raspberry. Later, the larvae find themselves in the ground, where they pupate, turn into beetles and hibernate until next spring.

  • treatment of raspberries from pests before throwing out the buds with Alatar, Fufanon, Kinmix KS
  • shaking off beetles from bushes onto a film or spread cloth in the morning (at this time the insects are lethargic)
  • application for the protection of biological agents Aktofit, Mospilan, infusions of garlic, hot pepper.

On a note! The use of any chemical insecticides is allowed only before the raspberry flowering phase and after picking berries.

Raspberry glass

Seeing black and blue butterflies with transparent wings similar in appearance to wasps near the berry in May or early June, the gardener must definitely treat raspberries with insecticides. This will save the insidious pest from laying eggs - a raspberry glass. The adults are not dangerous, but the larvae damage the core of the shoots of the shrub, which leads to the drying out and death of the plant.

Caterpillars spend the winter in raspberry shoots, at the base of a bush, and next year they pupate in the summer and after a while begin a new life cycle of butterflies.

How to get rid of a pest:

  • spring treatments with Decis, Karbofos, Nitrafen
  • spraying raspberry with Vermithek, Fitoverm, copper sulfate
  • cutting and destruction of shoots damaged by glass.

On a note! In the spring, the berry is sprayed before the young leaves bloom.

Stem raspberry fly

In the shoots of raspberries, another pest, the stem fly, makes clutches. Its size is small - up to 5 mm, color - gray. Legless larvae, off-white in color, devour the flesh of the shoots.

Clutches of eggs are usually located in the upper part of the stems, the larvae gnaw through entire passages inside, gradually moving down the shoots to the base of the bush. The plant withers, dries up, rots.

In the soil, the larvae hibernate, forming a pseudocoon, and in the spring, adult flies fly out. If you break a damaged raspberry stem, you can see a white worm. This is the fly larva.

  • cutting and burning young, wilting raspberry shoots
  • loosening the soil around the raspberry tree, mulching with the addition of tar, dry mustard powder, hot pepper
  • treatment with Actellik, Karbofos (before flowering)
  • spraying with biological agent Aktofit
  • processing of young growth with a soda solution (per bucket - 2 tablespoons of the product).

Gall midges on raspberries

On this culture, two types of gall midges can appear:

  • escaping
  • stem.

Both types of pest are dangerous, while the stem gives one generation of larvae, but the shoot gall midge, under favorable conditions, can have 2-3 clutches per season. A characteristic sign of the lesion: the formation of swellings up to 2-3 cm in size in the lower tier of the shrub on the stems - galls, in which the larvae of the insect are located.

The adults outwardly look like small mosquitoes (up to 2.2-2.4 mm long), the larvae are yellowish or orange. The peak of summer falls on the flowering phase of the bush, at which time the females of gall midges lay their eggs. The larvae feed on juice, the pulp of raspberry shoots.

  • regularly examine the shoots of raspberries, if swelling and wilting of the stems are found, the affected areas are cut out
  • for prophylaxis, the bushes are treated with the drugs Karbofos, Actellik, Iskra Double Effect.

On a note! The use of chemical insecticides gives little result, since the larvae are reliably hidden in the galls. Therefore, the main method is prevention and pruning of shoots in order to reduce the number of pests.

Raspberry kidney moth

The insect is especially dangerous for early raspberries. The adults are black with brown spots on the shiny wings of the butterfly, laying eggs in buds and flowers. The caterpillars gnaw the flesh of the ovaries, which are fruitier than the berries, descend into the ground and winter there in cocoons.

In the spring, the larvae attack the bushes again, penetrating the swollen buds. Then adult butterflies pupate and after a while appear. The pest causes great damage to plantings, damaging not only raspberries, but also blackberry bushes.

  • treatment of raspberries with insecticides during the emergence of adults (after picking berries) and in early spring (Karbofos, Fufanon)
  • loosening the soil under the bushes in the fall.

Raspberry-strawberry weevil

From the name of this insect, it is clear that you can see it not only on raspberries, but also on plantings of garden strawberries. The black beetle up to 3 mm long stands out among other similar insects with a long proboscis.

Lays eggs at the stage of flowering berries, one piece per bud. The hatched larvae devour the pulp of the buds, then pupate after 20-27 days and turn into beetles. Adults damage leaf plates, bush stalks, leaving holes in them.

  • manual collection of beetles (shaking off the bushes)
  • removal of fallen ovaries together with pest larvae
  • spraying with Inta-Vir chemicals, karbophos emulsion (before the buds come out and after the berries are picked)
  • treatment of bushes with Mospilan, Lepidocyte.


Aphids are truly a "scourge" of gardens and vegetable gardens, harming many plantings and, at the same time, distinguished by excellent survival. Most often, aphids infect raspberries located in low-lying places, in partial shade, with a large number of weeds. At risk are thickened, grassy berry fields.

Aphids attack shrubs in spring; during the blooming of young leaves, numerous gluttonous larvae appear. They occupy the leaves, petioles of raspberries, sucking the juice from the tissues of the plant. By the time the buds are exposed, the tops of the raspberry bushes literally stick around the aphid and its larvae.

On the leaves, streaks of honeydew appear - the secretions of aphids, which the ants feed on. The affected stems dry out, the growth of bushes stops, the leaves dry, curl. The danger of aphids also lies in the fact that it spreads many diseases, including the viral mosaic of raspberries.

What is being done to destroy the pest:

  • cut off the affected shoots together with the leaves and burn
  • treat bushes with infusions of calendula, tansy, yarrow. Decoctions of potato and tomato tops, infusions of tobacco, onion husks are prepared
  • with a large number of aphids, before flowering from pests, raspberries will have to be treated with chemicals - Actellik, Fufanon.

Sometimes gardeners knock down aphids with water by watering the tops of raspberry bushes with a hose or watering can.

Raspberry walnut

The traces of the presence of gall midges with lesions of the shoots of gall midges are very similar. The difference is in size, since the first bulges reach 8-10 cm.It is rare, mainly in regions located near forests. Adults are wasp-like, with a black body and transparent wings.

The larvae develop in galls - special compartments in the raspberry stems, which is why the affected shoots are covered with growths.There are several chambers inside the blisters, each containing one larva. When damaged, the stems wither, turn yellow, break.

Treatment of bushes with Aktellik, Ambush will help prevent the appearance of a pest. It is advisable not to allow mechanical damage to the stems and bark of the bush, since it is through cracks and deformations that the walnut most often penetrates inside.


A dangerous nocturnal pest that infects young leaves on bushes. Scoops appear in May, the greatest harm to the raspberry tree is represented by two types:

  • golden raspberry
  • garden.

Gray butterflies make clutches, brown or greenish-gray caterpillars emerge from the eggs, gnawing the flesh of the leaf plates. Without taking measures and exterminating the larvae, only veins remain from the leaves. The crop yield drops sharply, the bushes dry up and die.

  • cut off affected leaves
  • treat the bushes before budding with solutions of Inta-Vir, Karbofos, Fufanon.

Spider mites and raspberry mites

Not only flying insects settle on bushes. Of the arachnids, raspberry and spider mites love berries. It is easy to distinguish them: the first leaves a thinnest cobweb on the underside of the leaf plates, oily spots indicate the presence of a raspberry mite.

Ticks are most active in dry weather, affecting leaves. Pests overwinter in litter and plant debris (spiderweb), in the scales of the buds of the bush (raspberry mite).

On a note! The leaves affected by the raspberry mite appear discolored, which resembles a viral infection.

  • removal of diseased leaves with petioles
  • pruning old shoots (spring, autumn)
  • spraying of bushes with acaricides "Fufanon", "Metaphos".

For spring and autumn treatment of raspberries from ticks, special preparations (acaricides) are used, since ordinary insecticidal agents do not work on arachnids.

How to prevent pests

If there are signs of insect infestation, do not immediately use chemical insecticides. Their action is effective, but it is permissible only at certain times (before flowering and after harvest), since the preparations contain toxins (see video).

It is advisable to do with biopreparations or folk remedies that are safe for humans, or even better, try to prevent the appearance of a pest.

  • dig up the soil in the fall (this is how most of the wintering pupae and insect larvae are destroyed), the depth is at least 20-25 cm
  • remove weeds
  • be sure to thin out the bushes, cutting off diseased, deformed shoots
  • use mulch
  • cut off the affected shoots, leaves during the growing season
  • conduct regular inspection of the raspberry tree - leaves, buds, shoots
  • do low pruning of shoots (without leaving hemp) in the fall
  • carry out preventive treatments of the berry and adjacent plantings of other crops from pests.

A good effect is given by planting such strong-smelling plants as tagetes (marigolds), calendula (marigolds), dill next to bushes. For treatments in order to prevent insects, folk remedies are suitable:

  • infusions of tobacco, wormwood, tansy, onion husks, garlic cloves
  • decoctions of celandine, wood ash, tansy.

Spraying raspberries with these means is permissible in any phase of the growing season of the crop, while the "chemistry" can be used only before the formation of buds and after picking berries.

Pests are less likely to affect repair raspberries in household plots, but weevils, aphids, and spider mites are also dangerous for it. For example, the cultivar "Cumberland" is damaged by the raspberry beetle, aphid, and weevil. Control and prevention measures are the same as for traditional varieties.

Prevention measures

You can protect plantings from the invasion of insect pests using the following preventive measures:

  • deep autumn and spring digging of the earth
  • disinfection of seeds and beds before planting
  • pre-fertilization of the soil
  • compliance with the rules of crop rotation
  • no thickening of landings
  • watering not with cold water (better with settled water)
  • timely removal of weeds from the beds
  • regular inspection of plantings for the presence of insects.

The best precursors for peppers are legumes, green onions. The worst are zucchini, potatoes. For prevention purposes, it is recommended to spray the bell pepper with milk whey or soapy water.

Eliminate insect pests by virtue of special preparations and folk remedies. The formulations prepared on the basis of pharmacy products are safe and effective. Chemicals are used when massive insect colonies are observed on peppers. Prevention is the best method of fighting and protecting.
