Spring processing of raspberries from diseases. How to treat raspberries from pests and diseases

Many summer residents consider it senseless to find and apply efforts in the garden if, in the end, they do not have a good basket of sweet raspberries. A truly legendary berry, distinguished by its unique taste and sweetness.

Treatment

In order to get the richest harvest possible, the processing of raspberries should begin in the spring. This will be an investment for the future.

After the cold weather subsides, various insects will begin to get out of the ground, which will eat everything in their path. In addition, during this period, the risk of infection of the bush with various diseases and viruses is increased.

How to process raspberries? Normal will do garden pruner... After the snow melts, you need to remove all dried and unhealthy branches.

You need to prune before the plant wakes up and juice begins to run through it. Otherwise, the plant may get sick. The ideal period is the end of March, but our country has many climatic zones and this must be taken into account.

What should be done:

• Trim off dried tops.
• Broken or loose branches.
• Those trunks that can begin to grow inside the bush.
• Dried foliage.

Spraying

If you do not know how to spray raspberries during flowering, it is better to consult with experienced gardeners, this is the easiest and most reliable way not to hit your face in the dirt. If relations with neighbors are not established, and you do not have familiar summer residents, then let's figure out what's what.

In the spring, you need to take care of the processing of raspberries from pests. During this period, it is best to apply Bordeaux liquid and nitrophene.

These compounds are capable of destroying harmful spores and viruses that begin to wake up after a long hibernation. You can also additionally cultivate the land around the plant, this will reduce the likelihood of pests reappearing.

It is necessary to process raspberries with this composition before flowering and budding, because it is better not to disturb young flowers, which, due to stress, may not yield a harvest.

In the summer, raspberries are processed before flowering from pests if the spring procedures did not work. If signs of disease begin to appear on the bush and leaves, spots or leaves begin to turn yellow, you must first determine the disease.

If, for example, your bush suffers from powdery mildew, it is better to use the store-bought Topaz remedy. If you need to treat raspberries before flowering from pests, and you are against the use of chemicals, you can apply folk remedies, for example, a decoction of pine needles is able to destroy gray rot.

During flowering

There is still controversy over the question "Is it possible to process raspberries during flowering or not?" Each gardener decides for himself, and assesses the degree of possible risk.

Some believe that modern formulations are adapted for processing during the flowering period, but people of the old mind do not allow the thought of the contact of berries with drugs. The way out of this situation is folk remedies that are made from the same plants.

To fight fungal infections, a tincture of garlic and water is perfect. For cooking, you need to chop the head of garlic and throw everything into a bucket of water. After a few hours, the product can be filtered to remove excess garlic, and used to treat the affected areas of the bush.

By implementing micro pest control measures in spring and summer, you can increase your overall yield. In addition, he will be larger and healthier, since nothing will stop him from growing and filling.

It must also be remembered that the fight against fungi, infections and viruses must be combined with the fight against beetles. One large beetle can personally damage an entire bush.

Beetle control

The first treatment for all kinds of pests should begin before the first buds appear. Before spraying raspberries from pests, you need to remove the defective areas of the plant.

Bordeaux liquid is perfect for this purpose, it fights not only microscopic, but also large pests.

Just before the flowering period, you need to process the plant again, but this time with colloidal sulfur. However, it is used only in situations where the plant is threatened by a spider mite. Only the undersides of the leaves need to be processed.

Conclusion

If an ailment is found in a raspberry plant, you need to immediately take appropriate measures, otherwise you risk losing your entire crop.

In some cases, especially when the disease is running, you will have to get rid of the whole bush. This is necessary in order to stop the spread of the disease. The infected bush must be removed by the roots and burned.

Treating raspberries from pests helps prevent the appearance of various mites that suck the juices from the plant. Most often, it is recommended to treat raspberries from pests in the fall, since most ticks successfully overwinter in fallen leaves. Read on to learn how to treat raspberries in the fall for the winter against pests - two of the most common types of ticks are considered.

See what common raspberry pests look like in the photo and continue to study the variety of their species:

Raspberry mite

Raspberry mite Eriophyes gracilis Nal. - a very small pest, cylindrical in shape with two pairs of legs. Mites live and feed in leaf tissues, making moves and sucking out sap. In places of feeding on the leaves, bulges and folds of irregular shape are formed - galls. Folds on both sides of the leaf blade, numerous, at first yellow-green, later become discolored. The veins of the affected leaves are strongly curved, the leaf blades are deformed, brighten and dry out prematurely. Adult mites overwinter under the scales of buds, in spring, when blooming, they penetrate into young leaves and feed on tissue sap. Several generations of the tick develop over the summer.

Control measures. Preventive spraying in case of leaf fall in autumn with one of the drugs: fufanon, kemifom, actellik. Spraying is repeated immediately after flowering raspberries with the same preparations.

Common spider mite

Common spider mite Tetranychus urticae Koch. is a very small pest that feeds on the sap of young plant tissues. Has 4 pairs of legs. The body is 0.25-0.43 mm long, oval, greenish-yellow or orange-red. Females hibernate under plant residues and under the bark of trees and shrubs. In spring, young leaves are populated, feed, weave a thin web and lay eggs.

Larvae of each generation, depending on weather conditions, develop from 8 to 20 days. During the growing season in the open field, more than 10 generations of the pest develop. Damaged leaves turn yellow, deform, turn brown and dry out. In most cases, the tick spreads from nurseries with planting material as well as with various cut flowers and potted houseplants. This pest damages over 200 species different plants, including honeysuckle.

Control measures. Spraying plants when a pest appears and without fail in the fall before winter with one of the drugs: fitoverm, fufanon, kemifos, actellik, lightning.

How to treat raspberries from a pest earwig in the fall?

Before treating raspberries from pests in the fall, you need to know that the common earwig Forfucula auricularia L. is a large insect 13-20 mm long. The body is narrow, the head is well separated, with a gnawing mouth apparatus directed forward. The insect has two pairs of wings, the anterior elytra are leathery, often underdeveloped or absent altogether, the wings, when folded, protrude from under the elytra in the form of short plates. At the end of the abdomen there are two solid appendages, running legs, with three-segmented tarsi. The transformation is incomplete, the larvae are very similar to adult insects, but smaller in size. Earwigs are nocturnal; during the day they hide under leaves and branches or in cracks in the bark. They feed on both plant debris and vegetative plants, nibbling buds, young shoots, leaf edges, petals, inner parts of flowers.

Control measures. The first thing to treat raspberries from pests with an earwig is an insecticidal preparation, diluted according to the manufacturer's instructions. With a large number of pests, spraying is carried out with one of the drugs: fufanon, kemifos, actellik, Inta-Vir, taking into account the waiting time.

How to spray raspberries in the spring from pests of motley mares?

Before spraying raspberries in the spring against pests, it is necessary to clarify that the motley mare Jassus mixtus F. are small insects 6.5-7.5 mm long, with a wide pronotum and tetrahedral, densely spiked hind legs. Vertex rectangular, light yellow, rounded, in front with 6 dots located across, behind them there are 4 or 2 more dots. The forewings are brownish-yellow with many milky-white transverse veins and brownish-yellow merging spots and bands. It feeds on the sap of herbaceous plants, often found on shrubs, including raspberries.

Control measures. Preventive spraying during leaf regrowth and immediately after flowering with one of the drugs: fufanon, kemifos, actellik, kinmix, spark, Inta-Vir, aktara, fitoverm. When choosing how to spray raspberries from pests, you need to take into account the potential risk to human health.

Common spider mite

Before dealing with raspberry pests red-ass keel Acanthosoma haem-orrhoidalis L. , you need to understand that this is a large bug with a body length of 13-17 mm. The color is yellowish-green in small black dots, the abdomen, especially at the apex, is red, the first segment of the antenna is red, the spines of the prothorax are also red. The lateral angles of the pronotum are acute, strongly elongated. The larvae are similar to adult insects, but smaller. They feed on the sap of the tissues of deciduous trees and shrubs.

Control measures. Preventive treatment of raspberries in the summer from pests, during flowering or immediately after it, is carried out with one of the drugs: fufanon, kemifos, kinmix, actellik, caviar, Inta-Vir. With a large number of pests, repeated spraying in the summer with the same preparations is carried out.

How to protect raspberries from the redbug pest: fighting in the spring

Raspberry pest control in spring begins immediately after the snow cover disappears. Before you protect raspberries from a pest, the common redbug, or the soldier bug Pyrrhocoris apterus L., you need to know that this is a large sucking insect 9-11 mm long. The body is red, and the head, proboscis, legs, quadrangular spot in the middle of the pronotum, scutellum, clavus, membrane, 2 spots (small near the base, large in the middle) on the elytra, dorsal and lower abdomen are black. The abdominal rim is red, the chest is black with red edges, the membrane is shortened. There are no simple ocelli, the first segment of the proboscis almost equal to the length of the head. Insects with incomplete transformation. Adult bugs and larvae overwinter in cracks in the bark of trunks, stumps, under fallen leaves among dry shoots of bushes.

In spring they come to the surface, form large clusters, visible from the sunny side. From May, females lay eggs on herbaceous plants, hatching larvae feed on leaf juice until autumn. In autumn, the bugs descend into the base of the trunk, for some time they feed in large clusters on the shoots and grass, and with a decrease in temperature they crawl into the cracks of the bark for the winter. Redlops damages herbaceous plants, berry bushes and deciduous trees, especially linden and poplar.

Control measures. Preventive spraying in the spring, when the leaves are blooming, with one of the drugs: fufanon, kemifos, actellik.

Raspberry pests cause the greatest damage to the future harvest in the spring. Pests are especially dangerous remontant raspberry that continue to damage buds, flowers and ovaries throughout the season. Next, we propose to consider the most common types of these insects.

Raspberry-strawberry weevil

Raspberry-strawberry weevil, or raspberry flower beetle Anthonomus rubi Hrbst. , - a beetle 2.5-3 mm long, black, sometimes with a brown tint, covered with thick light gray hairs. Proboscis thin, slightly curved; antennae clavate. The larvae are grayish-white, curved, legless, with sparse hairs.

The weevil damages raspberries, strawberries, roses, as well as herbaceous plants from the Rosaceae family. Beetles hibernate under fallen leaves under raspberry and strawberry bushes. In the spring they come to the surface and feed on leaves, eating deep pits and small through holes in them. After additional feeding, the females lay eggs in the buds and gnaw the peduncle, causing the bud to break and fall off or remain hanging.

The larva develops inside the bud and pupates there. Young beetles emerge in the middle of summer and feed on young leaves until autumn, gnawing small holes in them. In autumn, beetles go to winter. With a large number of weevils, the yield of berry crops, especially strawberries and raspberries, sharply decreases. The pest is ubiquitous.

Control measures. Spring spraying of berry bushes during bud break and two weeks before flowering with fufanon or its analogues (kemifos, karbofos). With a large number of beetles in the summer, individual berry crops are sprayed with the same preparations. You can also use drugs kinmix, actellik, spark, Inta-Vir, taking into account the waiting time.

Fruit cutter

Fruit cutter Otiorrhynchus aurosparsus Germ. - weevil 7-9 mm long. All body dorsally and ventrally covered with small round light golden scales and short hairs. The larvae are thick, legless, white, curved, with a yellowish head, feed on the roots of herbaceous plants. Pupae are yellowish, open, with prominent legs, wings, and proboscis. Beetles gnaw leaf buds in spring, and later flower buds of raspberries. Skosar is polyphagous and causes great harm to berry bushes: raspberries, currants, gooseberries, as well as cherries and apricots.

Control measures. Preventive spraying in the spring, during bud break, with one of the drugs: fufanon, kemifos, actellik.

Study these raspberry pests carefully according to the descriptions with photographs, which are presented in large numbers further on the page!

Pests of raspberry beetles: photos and their treatment

Raspberry pests beetles Byturus tomentosus F . - insect 4.5 mm long, grayish-yellow in color. The larvae are up to 7 mm long, grayish-white, with brown plates on the back. Beetles hibernate in the soil, in early May they come to the surface. They feed on the buds and growing leaves of raspberries, skeletonizing them. Females lay eggs one at a time in flowers and on green ovaries. After 10 days, the larvae are born, bite into the receptacle and into the fruits and feed for 40 days. Having finished development, the larvae fall under the bushes and pupate in the soil, young beetles remain in the soil for the winter. Damaged berries quickly rot. Thickened planting of plants in the plots, the proximity of plantations of strawberries and raspberries, a large number of pests - all this leads to the fact that the raspberry beetle constantly harms on plantings of strawberries. Moreover, the leaves of overwintered bushes are very attracted to the emerging and hungry beetles.

Control measures. Compliance with all the requirements of agricultural technology for the cultivation of this crop. Preventive spraying of bushes before flowering against a complex of pests also reduces the number of horseradish beetles. With a large number of beetles and larvae in the summer, spraying is carried out after harvesting with one of the drugs: fufanon, kemifos, kinmix, actellik, Inta-Vir - taking into account the waiting times recommended for the drug used.

There are other pests of raspberries: the pictures below show their individuals of both sexes. It is told about how the fight against them is conducted on the personal plot. Some are visible to the naked eye. Others can only be recognized by indirect signs of their presence.

Raspberry flea

Raspberry flea Batophila rubi - a small beetle with a body length of 1.4-2 mm, black with a blue tint. The beetle jumps well. Harmful in July, skeletonizing leaves in the form of paths and small pits. Damages raspberries, less often honeysuckle. It is found singularly, so it does not do much harm.

Control measures. Preventive spring spraying of bushes against a complex of pests with fufanon and its analogues also reduces the number of fleas. With a large number, spraying is carried out in the summer.

Hidden head two-spotted

Hidden head two-spotted Cryptocephalus biguttatus Scop . - a small beetle 4.5-6 mm long with a short stocky body. The head has a steep forehead, retracted into the cervical plate. The elytra are black, with a wide red-yellow transverse spot at the apices. Legs, head, and pronotum black. It feeds on berry and ornamental bushes in May-June, nibbling on young leaves.

Control measures. Collection and destruction of individual beetles, preventive and eradicating spraying with one of the drugs: fufanon, kemifos, actellik, spark, Inta-Vir.

Video: Pest control of raspberries without chemicals

Before you save raspberries from sawfly pests, it is worth learning about what species exist. The following are descriptions of insects. It is told about how to water raspberries from pests of this type in spring and autumn.

Raspberry sawfly

Raspberry sawfly Monophadnus geniculatus Htg. - Hymenoptera with transparent wings. Larvae with 8 pairs of abdominal legs, light green with a dark line on the back, the head and pectorals are yellow-green. The larvae gnaw holes on the underside of the raspberry leaves.

Control measures. Preventive spraying in the spring, when the leaves are blooming, with one of the drugs: fufanon, kemifos, actellik, kinmix, spark, Inta-Vir. With a large number of larvae, spraying is carried out in the summer, taking into account the waiting times for the preparations.

Sawfly raspberry yellow-winged

Sawfly raspberry yellow-winged Arge cyanocrocea Forst . - Hymenoptera 7-8.5 mm long, with a black-blue head, breast and yellow-brown abdomen. The wings are transparent, yellowish at the base, with a brown band in the middle, darkened at the apex. The larvae are green, with a yellow-green head. The flight of adult insects is observed in May - July; after fertilization, the females lay eggs on raspberry leaves. The hatched larvae feed on raspberry leaves.

Control measures. Spraying before flowering and after picking berries in the fall with one of the drugs: fufanon, kemifos, actellik.

The fight against pests of raspberries with folk remedies ensures the purity of the future harvest. Next, let's take a look at those pests that you can use safe home remedies against. Usually, raspberry pest control is carried out in the fall and infusion of tomato tops, marigolds and some other means is used as insecticides.

Raspberry walnut

Raspberry walnut Diastrophus rubi Hart. - a small insect (2-3 mm) with a black body and a thin belly. The larva is white, legless, 1.5 mm long. The larvae overwinter in large galls on raspberry and blackberry stems. In the spring they pupate there; at the end of May, adult insects emerge from the pupae. Females lay eggs on young green shoots. The hatched larvae feed on the tissues of the stems, causing tissue overgrowth and the formation of galls. Damaged stems break easily and dry out, and the larvae inside the galls remain to winter.

Control measures. Timely cutting and burning of stems with galls. Preventive spraying of bushes in the spring when the leaves are blooming with fufanon or kemyfos. From folk remedies, dusting with tobacco dust helps.

Raspberry fly

Raspberry fly Pegomyia rubivora Cog. (syn. Chortophila dentiens Pand., Hylemyia dentiens Pand.) - a brownish-gray insect 5-7 mm long. The larva is off-white, without legs, cylindrical in shape, the head is not isolated. Eggs are white, oblong. The fly flies in May-June, feeds on the nectar of flowers and the sweet secretions of sucking pests. During the regrowth of green shoots, females lay eggs one at a time at the top and in the axils of the growing leaves. The larvae hatching after 5-8 days immediately bite into the shoot and feed, grinding a spiral or circular passage in the stem. The development of larvae lasts 12-16 days, after which they go into the soil to a depth of 5-6 cm, make an oval puparium and remain in it until the spring of next year. In the spring, the larvae pupate and after 7-9 days flies begin to emerge. In hot weather, they come out together, in 10 days, in rainy weather, the exit of flies stretches up to 20 days. In thickened plantings of raspberries, the fly damages up to 80% of young shoots. The tips of the damaged shoots wither and droop, and after two weeks they dry out. Lateral sprouts do not have time to lignify and most often do not overwinter. The raspberry fly also damages blackberries and meadowsweet.

Control measures. Spraying young shoots and soil before flowering raspberries during the flight of flies with preparations of fufanon or kemifos. Timely removal and burning of wilting shoots. Thinning of thickened plantings and compliance with all the requirements of agricultural technology for growing crops. The most effective folk remedy against this pest is laundry soap, on the basis of which a spray solution is prepared.

Gall midge raspberry stem

Gall midge mollina stem Lasioptera rubi Heeg . - small mosquito with a length of 1.6-2.2 mm. Body black, dorsum brown, covered with light yellow hairs. The wings are transparent, delicate, the legs are yellow-brown. The larvae are 3-4 mm long, fusiform, legless, orange-yellow in color. Pupae are closed in cobweb pseudo-cones. The larvae feed on the tissues of the shoots, causing the formation of tumors - galls measuring 3X2 cm. The larvae overwinter in galls, each of which can contain from 2 to 11 pieces. In spring they pupate in separate chambers. The flight of adult insects is observed in May-July. Females lay 8-15 eggs on young raspberry shoots. After 8-10 days, microscopic larvae hatch and crawl under the bark, feed on tissue juice and cause the formation of galls.

Control measures. The same as against raspberry nut-making. Folk methods are as follows: spraying with infusion of tops of tomato bushes.

Protecting raspberries from moths

The most common pests of raspberries are moths of various types. Protecting raspberries from this type of pest is challenging as butterflies can migrate long distances.

Raspberry baby moth

Raspberry baby moth Stigmella aurella F. - a very small butterfly with thin lanceolate wings framed by a fringe of shiny hairs. Wingspan up to 5 mm. The head is covered with dense hairs, the first segment of the antenna is widened. The caterpillar is flat, legless, amber-yellow, shiny, with a dark brown head, feeds on the leaf parenchyma, making a mine. The mine is serpentine, winding, starts from the top of the leaf, then, wriggling, ends at the median vein. The line of excrement is wide, intermittent. Two generations develop, caterpillars feed and develop in July and October. The baby moth more often damages the blackberry.

Control measures. Preventive spraying of bushes before flowering and after harvesting with fufanon and kemifos preparations.

Raspberry kidney moth

Caterpillars overwinter in dense white cocoons in cracks in the bark, in stumps or under leaves under bushes. In early spring, caterpillars emerge and bite into the buds, blocking the entrance with excrement. The caterpillar gnaws through the course to the middle of the shoot, having finished feeding, pupates in the same place or in the bud in a thin cocoon. Damaged buds dry up and can be distinguished by a wormhole sticking out of them. The development of pupae lasts several days, after which butterflies emerge from them. The flight of butterflies is observed during the raspberry flowering period. After fertilization, the females lay eggs, one in each flower. The hatched caterpillars feed on the fruitfulness of the berries until they ripen, then descend to the base of the shoots, weave a white cocoon and enter diapause until the spring of next year.

Control measures. Low cutting of old, fruiting shoots without leaving stumps, thinning and removing weak underdeveloped shoots, removing plant debris. Preventive spraying of bushes in spring, with bud break, with fufanon and kemifos preparations.

Raspberry moth one-color

Raspberry moth one color Tischeria tagginella Hw. - a small butterfly, the caterpillar of which feeds on the leaf parenchyma, making a mine. The caterpillar is greenish with a black head. A mine on the upper side of the sheet, at first narrow, ribbon-like, then wide with irregular projections. Inside the mine is lined with cobwebs, below there is a hole for dropping excrement.

Control measures. Preventive spraying of bushes when opening leaves with fufanon or kemifos preparations.

Despite the great number of remontant and classic varieties of raspberries, unpretentious, frost-resistant and undemanding to regular watering, most of them are susceptible to infection with viral and fungal diseases. Pests also cause serious damage to berry plantations. In order for the harvest on the raspberry to be regular, it is worth choosing the planting material more closely and feeding the plants to maintain immunity, to be able to provide "first aid" to damaged shoots and berries. Raspberries begin to be prepared for spring in September. The ability to use available tools, such as laundry soap and boiling water, will help you get a full harvest and healthy seedlings.

Do I need to process raspberries

V climatic conditions in the south and middle zone of our country, classic and remontant varieties of raspberries are equally well rooted and developed. But despite the approval of modern breeders, remontant hybrids require regular processing and are damaged by pests and diseases no less than classic raspberry varieties. Temperature drops during the growing season and during the dormant period, unfavorable environmental conditions, lack of nutrients can lower the plant's immunity and make it vulnerable.

In the event that an infected planting material appears on a personal plot, the entire fruit and berry plantation may suffer. Therefore, it is recommended to process them immediately after purchasing the seedlings. During the summer, the state of the plantings is monitored, if necessary, spraying is carried out and damaged shoots are removed. During fruiting, the shrub also requires attention, because not only beneficial insects live on the site, but also pests that like to feast on fragrant berries. For example, the larvae of the raspberry beetle are capable of destroying almost the entire crop, the leaf gall midge and weevil can damage young shoots. And anthracnose and bushy dwarfism harm the entire berry, while the gardener is unaware of this, because not all viral and fungal diseases are immediately noticeable. To enjoy berries, you cannot do without preventive treatments for raspberries.

A rich harvest of raspberries cannot be obtained without proper plant care.

Raspberry pests

The most dangerous pests of raspberries, widespread throughout our country - on industrial lands and personal plots, are stem gall midge, raspberry beetle and raspberry-strawberry weevil:

• Raspberry stem gall midge causes irreparable damage to the berry plantation - it lays its larvae in young shoots, thereby causing the leaves to wilt; the bark darkens and becomes covered with rough growths. To reduce significant harm from this insect, the raspberries are treated twice a season - in May, when the period of laying the eggs of the first generation of the pest begins, and after harvesting (the first decade of September). It is important to process the lower part of the raspberry leaves - this is where the female gall midges lay their eggs.
• Another ill-wisher on raspberries is a raspberry beetle, the female of which lays eggs in flower stalks. The larvae (worms) severely damage the fruit, they wither, rot and do not ripen completely. The offspring of the raspberry beetle can damage up to 50% of the crop. Adults eat buds and destroy flowers. Worms are activated in wet weather. In the fight against the pest, the most effective method- digging up the soil on the raspberry tree in which the beetle hibernates.
• Adult individuals of the raspberry-strawberry weevil harm juicy young shoots, and the larva prevents the formation of buds, thereby reducing the yield on the raspberry tree. The female lays the larvae in unblown buds, thereby providing comfortable conditions for the development of young insects. Raspberry flowers, ready to open, break and dry up. The colossal damage from the weevil is received not only by the raspberry plantation, but also by most of the fruit and berry bushes on the site.

Raspberry diseases

Wherever raspberries are cultivated - in the southern latitudes of our country or in the northern - there is a possibility of infection with fungal and viral diseases berry crops that affect the root system, shoots, leaves and berries.

Viral infections of berry trees develop as a result of the ingress of pollen from diseased plants or when using tools for pruning shoots infected with the sap of diseased plants. Complete elimination of this problem is unlikely, therefore, most often the diseased bushes are dug up and burned, green manures are sown in place of the old raspberry-tree, and a year later healthy material is again planted from the nursery. A preventive measure to combat viruses on raspberry plantings is the timely destruction of aphids, raspberry beetle, cicadas.

Dwarf bushiness (left), curliness (center) and chlorosis (right) are the main enemies of raspberries.

Fungal diseases are spread by insects that carry spores. Infected shoots must be cut out and removed from the site in a timely manner, fallen leaves and berries must be burned, raspberries must be planted in ventilated, sunny places.

Fungal anthracnose (left) is treated with copper-containing drugs, and wilt (right) is much more difficult to get rid of.

Raspberry diseases are aggravated by excessive thickening of the plantings and excessive moisture. Compliance with the agricultural technology of berry crops reduces the risk of infection with viral and fungal diseases.

When to process raspberries

Seasonal treatments of raspberry with folk remedies are no less effective than biological products of the new generation - subject to timely use.

Spring processing

In early spring, before bud break, abundant spraying of shoots and root space of the shrub is carried out with ready-made solutions (Actellik, Karbofos, Hom, urea, ammonia). Protective measures are effective against glass, aphids, raspberry beetle, weevil, anthracnose, curl. The procedure is carried out after the snow melts at a daytime temperature of + 5 ... + 10 ° С. In the middle lane - this is the end of March, in the south it occurs until the 10-15th of March. In Siberia and the Urals, the first spraying is performed not earlier than the beginning of April. They choose a sunny, windless day and start processing in the morning hours or at sunset.

Previously, overwintered mulch and plant elements are removed, the bushes are examined and sanitary pruning is carried out. After that, they begin to process raspberries with urea, copper sulfate or Topaz.

Dead raspberry shoots are cut (left) and treated with preventive solutions (right)

Processing raspberries in the spring at the stage of bud formation

At this time, it is recommended to repeat the spraying with copper-containing preparations and solutions that were treated until the buds bloom. In this phase, spraying with biochemical preparations (Fitoverm, Baktofit, Alirin-B), decoctions of herbs (wormwood, tansy, dill, marigolds) is still allowed. The moment of activation of the gall midge and the weevil is just approaching, the damage from which affects the future harvest. The base at the central shoot is watered with a suspension of tobacco dust and wood ash against chlorosis, glass and other larvae living in the soil.

If you skip the processing of the raspberry tree at the time of budding, you can lose most of the crop.

Autumn chores

After the last harvest of berries (this applies to remontant varieties), raspberry thickets are allowed to be treated with aggressive chemicals such as Fufanon, Actellik, Inta-Vir. This will help deal with ticks, raspberry beetle, hookworm, chlorosis, etc. The procedure is carried out in September-October. With the onset of cold weather, the soil in the aisles is dug up with the addition of wood ash (100 g per m2) and watered with copper or iron sulfate (according to the instructions).

Ash and copper sulfate - a means of combating soil pests

When digging in autumn, I use the "grandmother's method": I add chopped onion shells and husks to the soil - calcium and phytoncides will not interfere with the development of berry bushes, on the contrary, they will strengthen the plant's immunity.

Natural garden fertilizer - eggshells and onion skins

I repeat this procedure in the spring, if possible at the beginning of the growing season - I accompany the digging with watering with the addition of boric acid (3 g per bucket of water). After 7-10 days, I feed the raspberries with liquid mullein and urea diluted according to the instructions. It seems to me that regardless of the weather, there is an active growth of shoots, the leaves bloom faster and the bud formation phase begins.

Calendar for processing raspberries from diseases and pests

Raspberry processing begins when the buds are ready to open. The last spraying is carried out after the autumn pruning on the eve of the first frost.

Table: calendar of preventive treatments for raspberries

Processing time	Work on the raspberry
Before bud break (March, April)	spraying and root treatment from larvae and overwintered insects (copper-containing preparations and chemical - Hom, Fufanon, urea, and biochemical - Fitoverm)
During flowering (late May - early June)	treatment for weevils, gall midges, ticks, fungal diseases (urea, Bordeaux liquid, ammonia, mustard, herbal decoctions, boric acid solution)
After flowering (June)	prevention of pests and rot of shoots and fruits (urea, Fitoverm, Baktofit, herbal decoction, garlic and tobacco infusion, onion husk decoction, wood ash brewed with boiling water)
Fruiting (July - August)	spraying with infusion of tansy, tobacco, mustard and wormwood from weevils and raspberry beetle larvae
After falling leaves (September October)	treatment against putrefactive and fungal diseases, combating larvae and pests wintering in the trunk circle and bark of a plant (Fufanon, Fundazol, Actellik, ash, iron or copper sulfate)

How to properly handle raspberries

Applying folk remedies or biochemistry to carry out preventive spraying of shoots and soil, follow the rules:

• processing is carried out in calm, sunny weather (cool and dry);
• recommended:
  • use a respirator and gloves;
  • follow instructions and recipe.

Processing raspberries with copper sulfate

Copper sulfate CuSO4 (copper sulfate) is used to combat fungal and viral diseases of raspberries: curl, anthracnose, septoria, spotting. For raspberries, it is most often recommended to use a 0.5-1.0 percent solution to treat the shoots and the soil around them. To do this, dilute 50 g or 100 g of the substance per 10 liters of water at room temperature. One bush takes 0.5–1 liters of such a solution for spraying, or 1–1.5 liters for watering at the root.

Enough 1.5-2 liters of a liquid solution of copper sulfate for processing a raspberry bush

This drug is a prophylactic agent, not a panacea for raspberry diseases. In addition, copper sulfate is poisonous, therefore, during the growing season, it is not treated with it - it accumulates in the berries and the crop after spraying becomes not edible.

Processing raspberries with iron vitriol

Iron vitriol is iron sulfate, the powder of which is used to combat pests on raspberries (slugs, larvae), from fungal spores, mosses, lichens. In addition, this drug is a catalyst in the formation of chlorophyll. In the raspberry tree, it is the first enemy for chlorosis and anthracnose.

In the spring, after pruning dry and damaged branches, the plant is dug in and fertilized with cow dung or chicken dung with the addition of ferrous sulfate powder - 100 g of substance per 10 kg of fertilizer.

To get rid of fungal diseases, dissolve 250 g of iron sulfate in 10 liters of water at room temperature and spray the plants (200-400 g per bush).

Autumn processing is carried out after the leaves have fallen off. So that lichens and moss do not annoy the berry beds, the lower part of the shoots (15–20 cm) is covered with a solution of ferrous sulfate - 100–150 g per 10-liter bucket of water. This amount is enough for a whole raspberry plantation.

Proven prophylactic against fungi and lichens on raspberries - iron vitriol

Processing raspberries in spring with boiling water

When sap flow has not yet begun, at the end of winter or early spring, raspberry bushes are watered with boiling water - the cheapest, but time-consuming way to get rid of pest larvae wintering in soil on a raspberry tree. The easiest way is to process remontant raspberries in this way, they are cut flush with the ground for the winter, so less hot water and less effort for watering will be required.

10 liters of boiling water is carefully poured using a garden watering can with a nozzle. At the same time, they try to get hot water on the upper part of the shoots and the root space, on the soil around the bush.

Boiling water will require effort - a watering can filled with water should be raised high above the bush to capture the entire aerial part of the shoots

Sprinkling raspberries in spring with urea

Urea (carbamide - carbonic acid diamide) helps against diseases (spotting, rust, anthracnose) and pests that are still at the wintering stage (larvae of a raspberry beetle, glass butterflies), therefore, processing is carried out in early spring before the beginning of the growing season of the plant. To do this, take a concentrated solution - 400-500 g of substance per 10 liters of water and spray it. With this amount, you can process 10 acres of raspberries.

In addition, urea saturates raspberries with nitrogen, strengthens their immunity, preparing the plant for active growth and fruiting. For dressing use a concentration of 50 g per 10 l of water. Raspberry bushes are watered at the root. Liquid cow dung concentrate or tobacco dust tincture can be added to the urea solution.

I try to carry out the treatment with urea twice in the spring. The first time - before bud break - I process it against pests, watering the root space or spraying it with a broom - the solution gets both on the shoots and on the soil. To do this, I dilute 500 g of the substance in a 20-liter plastic barrel (2-3 liters per raspberry bush is quite enough). The second time I repeat the procedure in 10-14 days. Now this is abundant watering with a complex feeding of my own preparation: I add 5 g of boric acid, 3 liters of mullein infusion and 50-100 g of wood ash to a 10-liter bucket of water at room temperature. I mix everything thoroughly and water it at the root (1 bucket per 1 m 2).

Processing raspberries with Bordeaux liquid

A universal remedy for the comprehensive protection of berry crops from diseases is Bordeaux liquid. The drug contains copper sulfate and quicklime in a 1: 1 concentration, is a blue liquid. The remedy is effective for anthracnose, powdery mildew, different types spots on raspberries. At the same time, the drug is toxic, therefore, it is allowed to treat plants with copper-containing agents in early spring or late autumn.

The finished preparation of Bordeaux liquid is used to process most fruit and berry crops in the garden

Before bud break, the affected bushes can be treated with a 3% solution of Bordeaux liquid (300 g of the finished solution per 10 liters of water) with the addition of a 2% solution of potassium salt.

To prevent the spread of infectious ailments, it is best to carry out the treatment with Bordeaux liquid in the autumn - late September - early October. The finished solution is filtered and processed in dry, calm weather.

You can make Bordeaux liquid yourself. For this, slaked lime (fluff) and copper sulfate are bought separately. For preparation, take 100 grams of vitriol and 75 grams of lime, dissolve each substance in 10 liters of water separately. Then the liquids are combined, receiving a 1% solution of Bordeaux liquid.

The solution of our own preparation is thoroughly filtered, otherwise the lime suspension will quickly clog the sprayer.

Processing raspberries with mustard and soda for worms

To prevent the appearance of worms in berries, it is useful to treat raspberries with a solution of dry mustard: add 20 g of powder to a 10-liter bucket of water, filter and abundantly spray the bushes from a spray bottle. Another way to get rid of larvae on raspberries that damage berries is soda. Prepare a solution of 50 g of soda ash and 50 g of household soap for 10 liters of warm water. Spraying is toxic, therefore, if necessary, it can be repeated at intervals of 2-3 days.

Since the larvae of the raspberry beetle hibernate in the soil, it is recommended to carefully dig up the ground around the raspberry shoots with the addition of wood ash.

Drastic measures - before the appearance of buds, spray with Guapsin and Trichophyte preparations - 5 ml per 10 liters of water. According to experts, these substances contain beneficial bacteria and are absolutely safe for humans.

Dry mustard (left) and guapsin (right) are used to get rid of worms in raspberries.

Treatment of raspberry with ammonia

As part of ammonia contains ammonia, which, after processing by soil microbes, turns into nitrates, which are necessary for the development of green mass. It is a concentrated fertilizer used in spring. Also, the drug is used to treat raspberry shoots and foliage against pests and diseases.

Method of solution preparation: 30-40 ml of pharmaceutical ammonia 10% is diluted in 10 liters of water at room temperature and the plants are watered from a watering can with a sprinkler. The finished product is used at the rate of 2-3 liters per one bush. Processing is carried out in early spring.

Processing raspberries with tar

To protect against the raspberry-strawberry weevil, the bushes are treated with a solution of birch tar. For this, a liquid suspension is prepared: 60-100 g of tar are taken for 10 liters of water, and raspberries are poured with the finished liquid in early spring. Approximately 5–7 liters is spent on processing one plant. This is an absolutely safe method of dealing with pests overwintering in the soil.

Folk remedies for processing raspberries

It should be processed with tinctures and solutions prepared according to folk recipes in spring, summer (before flowering) and autumn. During the formation of the ovary, treatment with herbal infusions is possible; during fruiting, they should be discarded. Infusions and decoctions have a specific smell and can be bitter, which can affect the taste of berries.

Several ways to process raspberries using folk remedies:

1. One liter of whey or yoghurt with the addition of 10-15 drops of a pharmacy iodine solution is stirred and filtered; the composition is used for spraying against late blight and rust.
2. Jars of sand soaked in chloramine or kerosene are placed against the glass.
3. For fungal diseases, a solution is prepared from 1 liter of water, 500 g of milk and 100 g of salt and is used as a spray from a spray bottle.

Milk whey, iodine and salt are the main elements for preparing solutions for processing raspberries according to folk recipes

Many gardeners use pine needles as a remedy for gray rot. Pine or spruce branches, coniferous litter are laid out between the rows of raspberries or the plantings are sprayed with broth of needles. For this, 0.5 kg of plant substrate is poured with 3 liters of water, boiled for 10-15 minutes and left for 2-3 hours. During this time, the liquid will cool down to about 40 ° C - the broth is ready for processing. It is sprayed over the tops of the raspberry shoots with a wide paint brush or a homemade broom made from dry grass. It is not recommended to spray the broth with a sprayer, since the resin contained in the needles settles on individual parts of the sprayer and disables it.

Broth of needles is effective against gray rot on berry bushes and is absolutely harmless

The best option is to mulch the root space of the beds with raspberries with coniferous litter. And also for these purposes, onion peels are often used. Onions contain phytoncides that repel pests.

Garlic infusion is used for spraying against pests and fungal diseases. The solution is also used in the fall to water the soil from the larvae of the raspberry beetle. To prepare an infusion of garlic, cut off the shoots of the plant (half a bucket of herbs for 5 liters of liquid) or chop the cloves of garlic (10-15 pieces for 0.5 liters of water). The green mass or crushed garlic is poured with boiling water and left for a day to settle. The liquid acquires a pungent specific odor, which repels pests.

Garlic - a sure remedy for diseases and pests of raspberries

Grind 200 g of chives in a mortar to the state of gruel, then place it in a 1 liter jar and fill it with warm water to the top. A jar with a closed lid is left in a dark place for 5 days (at a temperature of +20 +25 ° C), periodically shaking the contents. Then the infusion is filtered, poured into a dark glass bottle, corked and placed in the refrigerator. In case of aphid infestations on raspberries, 100 ml of infusion is poured into 5 liters of water and the affected area is abundantly moistened with a solution using a paint brush.

A decoction of tansy, yarrow, wormwood and dandelion is used to combat ticks, fleas and aphids on raspberries. Spicy herbs are bitter and have a pungent smell, which repels pests. The broth is recommended to be used at the stage of fruit setting.

• Dry branches of wormwood (0.5 kg) pour 3 liters of boiling water and leave for 12 hours. The spraying process is carried out after the infusion has been filtered. According to the same recipe, an infusion of tansy herb is prepared.
• Dandelion is used in the form of a decoction and infusion of fresh green mass: leaves, flowers, stems.
  • The first method: about 3 liters are poured so that the water covers the chopped ingredients. They put on a quiet fire and boil for half an hour. The solution is allowed to cool, then the berry bushes are filtered and sprayed. Five liters of broth is enough to process 10-15 raspberry bushes.
  • The second method: 1 - 1.5 kg of fresh chopped dandelion herb is insisted in a bucket of water for two days. The infusion is drained and irrigated with raspberry shoots from a watering can with a sprinkler.

Broths of wormwood (left), tansy (center) and dandelion (right) are prepared for the preventive treatment of raspberries from diseases and pests

Raspberry bushes are treated with herbal infusions immediately after flowering 3-4 times with an interval of 5-7 days.

Therefore, in order to get a decent harvest of raspberries, one cannot do without preventive treatments.

All procedures for processing raspberries begin in early spring before bud break. Before processing, the bushes are examined, patients and.

All agrotechnical methods for combating diseases and pests are carried out in three steps:

1. Before bud break.
2. Before the beginning of abundant flowering in the last decade of May.
3. Before setting fruit.

What to process

Chemical, biological and folk remedies can be used when processing the berry. Each of the methods is used at certain times of the raspberry growing season:

• chemical are involved only before raspberry blossom;
• biological are used throughout the growing season;
• folk are used for any period of cultivation.

Biological agents

Biofungicides and bioinsecticides are a product created as a result of the metabolism of microorganisms that have a detrimental effect on pathogens on harmful insects. Treatment of plants with such preparations allows you to get environmentally friendly berries. However, most biologics do not have a systemic effect.

Raspberry bushes - description

The sinuous woody rhizome of raspberries forms many adventitious roots, due to which the raspberry root system becomes powerful and very branched. Erect stems reach a height of one and a half to two and a half meters. The shoots of the first year are grassy, ​​juicy, gray-green, covered with frequent, thin, small thorns. In the second year, the shoots turn wood and turn brown, and after fruiting they dry out, but instead of them new green stems grow the next spring.

Raspberry leaves are petiolate, alternate, complex - with three to seven oval leaves, the upper side of the leaf plate is dark green, and the lower one is whitish because of the fine pile growing on it. Small racemose inflorescences of white flowers about one centimeter in diameter are located in the axils of the leaves or at the tops of the stems.

The raspberry berry consists of small hairy drupes that have grown together into a complex fruit. Most often, red raspberries of various shades are grown, but yellow raspberries and even black raspberries are also cultivated. After planting, raspberries usually begin to bear fruit the next year, in the very first year flower buds are only laid on its stems, from which then, from next spring, fruit branches develop. However, today, thanks to the efforts of breeders, there are remontant varieties of raspberries that bear fruit on the shoots of the first year.

Raspberries turn yellow

Very often, site readers are concerned about the following questions: why do raspberry leaves turn yellow and what to do if raspberries turn yellow? If this happens in the fall, then you are most likely seeing a natural seasonal change, but if the raspberries turn yellow in the spring or summer, this is an alarming sign. There are several reasons for this phenomenon, and one of them is bacterial diseases of raspberry root cancer and goiter of roots. The symptoms of these diseases are similar: growths in the form of tubers form on the roots of the plant, the growth of shoots stops, the leaves of raspberries turn yellow, and the berries lose their sweetness.

Most often, plants get sick in areas with slightly alkaline or neutral soil. To avoid infection with root cancer or goiter, carefully examine the raspberry seedlings before planting, and if you see swelling on the roots, remove the affected part of the rhizome, and treat the cut with a 1% solution of copper sulfate.

Raspberry leaves also turn yellow from various kinds of mosaics - viral diseases manifested on raspberry leaves by reticulation, mottling, spotting or stains. There is no cure for viral diseases, so try to protect raspberries from infection with mosaics with good care and preventive treatments of the bushes against aphids, which are the carrier of the disease. Remove and destroy diseased specimens immediately from site.

Sometimes the premature yellowing of the leaves occurs because your raspberry tree is too thick - the thickets are poorly ventilated, the plants do not have enough light. Do a good pruning and thinning of the bushes, and then feed the plants with chicken droppings or rotted manure.

Raspberry chlorosis

Another answer to the question why does raspberry turn yellow, there may be causative agents of viral diseases that penetrate the tissues through cuts and fractures of the cortex. The carriers of viruses are insects - nematodes, ticks or aphids, which expose raspberries to such a serious disease as jaundice or chlorosis. First, the areas of the leaf plate between the veins turn yellow, then the yellowness asymmetrically spreads over the entire leaf, and it wrinkles. The shoots are stretched, thinner, the berries become small, deformed and dry quickly.

Too wet soil and too high acidity of the soil on the site provoke the development of infection. You can shift the reaction to the alkaline side by adding gypsum to the area for digging at the rate of 120 g per 1 m², and excess moisture is eliminated by reducing irrigation. And be sure to destroy the insects that carry the infection. If your raspberries get sick with chlorosis, you will have to dig up the affected specimens and burn them, and in the place where they grew, it will be possible to grow raspberries no earlier than ten years later: there is no cure for chlorosis yet.

Raspberry curl viral disease

The leaves of diseased plants become smaller, wrinkled and tough, and the underside of the leaf plate becomes brown. The berries on diseased bushes become sour, deformed and dry out, and the plant itself dies within three years. Be careful, inspect the planting material for symptoms of the disease, because this disease cannot be cured, and the affected plants must be immediately removed from the site and destroyed.

Mycoplasma disease

There is another harmful disease of raspberries, which is called overgrowth, or "witch's broom": the plant forms a lot of non-fruiting small shoots from 30 to 50 cm high - up to 200 per bush. If such a specimen appears on your site, destroy it immediately, before the disease spreads to neighboring bushes, because this disease cannot be cured either. Cicadas could have brought it to the site, or the causative agent of the disease came to you with planting material, so be careful when buying and planting raspberries and destroy pests.

Raspberries dry

Another question that our readers often ask: why raspberries dry? This happens as a result of a violation of the rules for caring for raspberries. Here are the reasons why the leaves and even the stalks of raspberries dry out:

• lack of moisture;
• nitrogen hunger;
• too dense planting and, as a result, insufficient lighting.

Examine the condition of your raspberry tree, identify and correct your mistakes, and do not neglect the annual pruning of second-year fruit-bearing shoots.

Raspberries also dry out from diseases, the description of which is given below, as well as from shoot and stem gall midges - pests, which will be discussed in a separate chapter.

Raspberry rust

Sometimes the fact that raspberries dries are due to fungal diseases of raspberries, one of which is rust. In May, dark spots appear on the underside of the leaf, raspberry leaves dry and fall off, brown ulcers appear on the stems. Sick bushes will have to be destroyed, because rust cannot be cured, but preventive measures can be taken to prevent raspberries from becoming infected with this disease. Spring and autumn treatment of raspberries with a 1% solution of Bordeaux liquid will protect the bushes from damage by this fungus.

Raspberry speck

More often than rust, raspberries are affected by purple speck, or didimella, as a result of which the raspberries dry out. First, light purple spots appear on young stems, which gradually blur and darken along the edges to a reddish-brown color, and black dots - pycnidia appear in the lighter center of the spots. Over time, the spots merge, their surface cracks, shoots break, and buds do not develop on them. In wet summers, the disease can affect the entire area.

Destroy the specimens infected with the fungus, treat the bushes with a 1% solution of Bordeaux liquid: the first time, when young shoots reach a length of 15-20 cm, the second time before flowering, the third time immediately after flowering and the last time after harvesting. Do not overgrow the area.

Powdery mildew on raspberries

A dangerous fungal disease is powdery mildew, which covers in the first half of summer, especially if the weather is wet, the ground parts of raspberries are covered with a white loose bloom, which causes the leaves to dry and the berries are deformed. If you find powdery mildew in a raspberry berry, immediately after harvesting, treat the plants the same, the same number of times and with the same remedy as for other fungal diseases.

Raspberry anthracnose

Anthracnose is also a fungal disease that raspberries often suffer from in the garden. Small gray spots with a purple rim appear on the leaves and stems of the plant, growing, merging with each other and forming ulcers, due to which the leaves fold and die, the bark exfoliates on the stems, and the berries do not have time to ripen, deform and darken. You need to deal with anthracnose using the same methods as with any other fungal disease.

A neglected and thickened raspberry tree can also be affected by ulcerative spotting of the stems and autumn spotting - fungal diseases, the ways of dealing with which we have already mentioned to you, talking about purple spotting. Try, if the raspberries are dry, immediately remove the dry stems so that insects that carry diseases do not settle in them, and it is advisable to cut off green shoots if they are weak or directed towards the inside of the bush.

Pruning is the sanitization of the shrub, and if done correctly and at the right time, it strengthens the raspberry's resistance to diseases and pests, which also tend to inhabit the weakened plant.

Raspberry leaves curl

This is a symptom of raspberry anthracnose disease, which we wrote about above, but sometimes leaf deformation does not indicate a disease, but a lack of one or another element in the soil - for example, boron or potassium. If the point is a lack of potassium, then the raspberry leaves are wrapped upside down. The lack of potassium can be corrected by feeding raspberries with ash, and the deficiency of boron is eliminated with a solution of boric acid introduced into the soil at the beginning of summer.

Aphids on raspberries

Raspberry leaf aphids and raspberry shoot aphids are widespread pests of raspberries, blackberries and other garden berry crops. Shoot aphids settle in colonies at the ends of shoots and in raspberry inflorescences, and leaf aphids live in small groups on the underside of leaves and feed on their juice. The shoot aphid slows down the growth of raspberries, and the leaf aphid, in addition, is a carrier of viral diseases. The method of combating aphids consists in spraying the plants with karbofos or actellik during the period of raspberry budding.

Spider mite on raspberries

This insect affects not only raspberries, but also gooseberries, black and red currants, strawberries, blueberries, elderberries, roses and grapes. The mite, located on the underside of the leaves and feeding on their sap, braids the leaves with a thin cobweb. The damaged areas become discolored, with the course of the disease, the leaves become marbled, gradually dry and eventually fall off. The harbinger of the appearance of ticks on raspberries is a stable and prolonged heat without precipitation.

An effective measure in the fight against ticks is spraying raspberry bushes (gooseberries, currants, etc.) with acaricides, which include drugs such as malofos, phosphamide, colloidal sulfur, cydial, metaphos. If the dominance of ticks is too strong, the treatment of plants with acaricides can be carried out repeatedly - up to four times a season with an interval of ten days. In order not to create a comfortable environment for ticks, in addition to watering in arid heat, they practice spraying the bushes with water in the evening.

Gall midges on raspberries

Two types of raspberries and gall midges are harmful - the raspberry gall midge, or the shoot gall midge and the raspberry stem gall midge, laying eggs in cracks and damage to the bark on the lower part of the shoots, forming galls - swellings. In the affected shoots, the bark dies and exfoliates, they dry out. Shoots with characteristic features lesions (swelling in the root areas of the stems) must be cut out and destroyed together with the pests, the soil in which gall midges winter in spring and autumn must be dug to a depth of 15 cm, and the plants must be treated with karbofos or actellik.

The raspberry nut-maker behaves in a similar way, laying the larvae in the raspberry shoots, on which galls are formed from this. If this pest is detected, it is necessary to spray raspberries with the same karbofos or actellik, as well as ambush, before flowering.

Raspberry beetle

This is a medium-sized insect up to 4 mm in length, covered with yellow or gray hairs. It hibernates in the upper soil layer, and by the end of May it migrates to raspberry buds and eats them away, also damaging open flowers and leaves. At the end of July, the larvae return to the soil again, pupate there in order to turn into beetles in the fall.

It is necessary to get rid of raspberry beetles during the budding period, shaking them off the bush and destroying them. It is obligatory to dig up the soil under the bushes and in the aisles during the pupation period of the larvae. Good results in the destruction of this pest are obtained by spraying raspberries with confidor, decis or ten percent solution of karbofos.

Strawberry-raspberry weevil

This bug harms not only raspberries, but also strawberries, therefore, the appearance of a weevil on summer cottage highly undesirable. Beetles overwinter under fallen leaves and clods of earth, and in spring they lay eggs in buds, where the larva feeds on a flower, eating it from the inside. One female weevil, laying one egg per bud, is capable of damaging up to 50 flowers in this way. In June-July, a new generation of leaf-eating weevils appears.

To prevent the beetles from destroying the crop, spray the raspberry plant during budding and no later than five days before the flowers open, with malofos, actellic, metaphos or other preparations of a similar effect.

Raspberry kidney moth

It is a butterfly with dark brown wings with small golden spots, a moth caterpillar is red with a dark brown head. Most of all, this insect harms early raspberry varieties. Caterpillars hibernate in cracks in stems or under plant debris on the ground, and in early spring they move to shoots and gnaw out the buds, and then penetrate into the flesh of the shoot, pupate there at the end of May, and from the beginning of flowering of raspberries, butterflies fly out of pupae, laying eggs in raspberry flowers ... The caterpillars emerging from them eat the berries, destroying the raspberry crop.

In order not to help the bud moth to reproduce, do not leave stumps from them when pruning old shoots. Spray the raspberry bush with confidor, spark, decis, or 3% karbofos emulsion in early spring, when the buds are just starting to swell.

Raspberry stem fly

It is also a dangerous pest, the larvae of which gnaw out spiral passages inside the stems from above to the roots, causing the tops of the shoots to wither, then turn black and rot. When flowering begins, the larvae go into the soil, where they hibernate and turn into butterflies that fly out in the spring and lay the larvae, eating the stem from the inside. Examine the bushes carefully and immediately cut off the affected shoot tops to a healthy stem. Spray raspberries with actellik or karbofos in early spring, when they are just starting to grow shoots. In the fall, remove fallen leaves from the site.

Raspberry glass behaves in about the same way, but it prefers to winter in the core of the stem or root of the raspberry, forming swellings on them. That is why it is very difficult to destroy it with an insecticide. Cut out old shoots that will no longer bear fruit, without leaving a hemp from them, make sure that there are no cracks and mechanical damage on the stems.

How to process raspberries - prevention

Processing raspberries in spring

As soon as the snow melts and the ground starts to warm up, put things in order in the area where the raspberries grow: cut off the frostbitten tops of the shoots, remove the stems that are broken or differ from others in color, as well as those that grow inside the bush. Rake up last year's foliage and burn it, and apply nitrogen fertilizers to the soil on the site and embed them in the ground. After that, tie the raspberries to the trellis and once again inspect them for trimming - something you might have missed.

Treatment of raspberries from diseases

It is best to spray raspberries in spring with nitrafen or Bordeaux liquid as a preventive measure, and you need to process not only the bushes, but also the soil under them. The first spraying should be done before the buds begin to bloom. Whether it will be necessary to repeat the treatment in spring and summer depends on what kind of ailments you noticed in raspberries last year. However, after harvesting, it is necessary to carry out the last treatment of raspberries and soil under the bushes with nitrafen or Bordeaux liquid this year in order to destroy pathogens that could appear on raspberries during the summer months.

Pest control of raspberries

In early spring, before the buds bloom, treat the raspberries with karbofos or actellik. If you carry out such processing twice a year, cut off unnecessary stems in time and observe the agrotechnical conditions for growing raspberries, then you will not have to complain about the health of the plant or the harvest of fruits. If during the last growing season you noticed some pests on raspberries, then fight them using our information - treat raspberries with insecticides in accordance with the type of pest and as many times as necessary to get rid of it. The last treatment with insecticides in the season must be carried out after the harvest.

Processing raspberries in the fall

Feeding raspberries

How to feed raspberries

You need to start fertilizing raspberries even during planting, embedding them in the soil for digging a large number of manure and mineral fertilizers... After that, the need for feeding arises only after two seasons, that is, in the third spring. In the spring, raspberries need nitrogen fertilizers, which must be applied annually over the snow at the rate of 8 g of urea or 12 g ammonium nitrate one square meter.

In the fall, 100 g of ash must be added to the soil (as potash-phosphorus fertilizers) and 6 kg of humus or manure for the same unit of area - autumn dressing is applied once every two years and only if you have not used manure or humus as mulch. The exception is raspberry beds located on sandy loam - such soil requires annual fertilization. Loamy soils need to be fertilized every two years, but the dosage is increased by a quarter. Manure can be successfully replaced with compost by adding ash and mineral fertilizers to it.

Fighting raspberries

How to deal with raspberries

All raspberry varieties give root growth - some less, others more. This growth spreads over the raspberry tree, and if you gape, then it will appear even where it should not be. The easiest way is to trim unnecessary shoots with a sharp shovel to a depth of ten centimeters, but leave them in the same place where they gradually dry out. In order to protect the garden from the penetration of raspberry shoots into it, the raspberry tree is fenced with pieces of slate dug into the ground to a depth of 35-40 cm.

You can also plant garlic or sorrel, or even better beans, around the raspberry bushes, and this measure can stop the growth of the growth. If you grow raspberries on the site not in a ribbon, but in a bush method, then you can plant it in barrels or buckets dug into the ground without a bottom, and then the root system will not grow in breadth and, therefore, will not be able to give growth. It is noticed that the introduction of nitrogen fertilizers not in spring, but in autumn, significantly reduces the number of basal shoots.
