- 10 liters of water;
- 10 grams of tar;
- 40 grams of laundry soap.
Processing is carried out until the first buds appear on the raspberry
Infusion of citrus
From folk remedies for the prevention of pests, an infusion of citrus fruits (orange, lemon) is used.
Take 50 grams of fruit peels, pour hot water (1 liter), incubate for 3-6 days. Then spray raspberries before flowering.
Soap and soda solution
From aphids, both a simple soapy solution and in combination with baking soda help.
Soap chips (300 grams) are first dissolved in a liter of warm water, then a spoonful of soda is added there. If soda ash is used, then the amount is reduced by half.
The milk mixture is prepared simply: 1: 1, while you can take both sour milk and whey, low-fat kefir. The resulting composition is sprayed with raspberries in the spring, as well as at the time aphids appear on the leaves of plants.

Boiling water treatment
The most low-cost and easiest way to process raspberries in the spring is to water the bushes with boiling water. This technique allows you to get rid of the larvae of pests that winter in the layers of soil.
Boiling water is poured over the soil around the plants, and the upper part of the shoots is also very carefully watered.
Spring processing of raspberries is an important measure of agricultural technology, which allows you to get a healthy harvest, as well as facilitate the work of gardeners in the summer.
Raspberries cannot be considered more prone to various diseases and pests than other crops, although it is, of course, susceptible to these misfortunes. Therefore, a number of measures for the prevention and treatment of diseases and pest control must be carried out without fail in order to have a good guaranteed harvest.
Processing raspberries from harmful insects
Not only people love delicious and fragrant raspberries. A complete list of insect pests of this plant can scare even an experienced gardener:
- raspberry beetle;
- raspberry (raspberry blueberry);
- raspberry stem gall midge (raspberry mosquito);
- raspberry nutcracker;
- shoot aphid;
- raspberry-strawberry weevil;
- glass case.
Photo gallery: insects - pests of raspberries
Raspberry stem gall midge feeds on raspberry juice, making passages inside the shoots 
Raspberry beetle eats flowers and tender raspberry leaves 
Blueberry raspberry feeds on raspberry flowers 
Raspberry-strawberry weevil destroys the buds of raspberry flowers, laying their eggs in them
However, as a rule, one of the following means acts against this entire list. When aphids, raspberry beetles, mites and other harmful insects appear, you can first try to get rid of them in the simplest way - dust the bushes with a mixture of tobacco dust and wood ash in a 1: 1 ratio. Along the way, wood ash serves as a complete foliar top dressing with a large number of trace elements. This method can be applied at any time, except for flowering, because it will also repel pollinating insects. It is also undesirable to get tobacco dust and ash on ripe berries. If aphids and beetles are hidden from processing in twisted leaves or on the back of the leaf, the method may not work. Then use the recommended drugs:
- Prestige.
Each of the drugs has its own terms of use.
This is an inexpensive and easy-to-use preparation of contact-intestinal action. Its active ingredient - imidacloprid - gets on the foliage, and then in the food of the insect. Imidacloprid also acts as a contact poison: when it hits the chitinous membrane, it penetrates inside the insect. Available in powders, granules, but most often in the form of a solution:
- in ampoules of small capacity (3.9 g);
- large capacity - for processing large plantations (50 and 100 g).
Spray raspberries in the spring, on blossoming leaves, as pests appear. The term of protection is up to 3 weeks.
Advantages:
- although Biotlin is labeled as an aphid and whitefly control, it is capable of destroying any small harmful insect;
- low toxicity for humans and plants, belongs to the low 3rd hazard class;
- as a rule, one treatment is enough before harvesting.
Flaw:
The drug belongs to insecticides of intestinal action of industrial production, but it is not a chemical, but a biological drug. Its active ingredient aversectin C is made from fungi of the genus Streptomyces. The drug acts after a while: 12 to 72 hours, and for individual insects - up to 7 days. Immediately after taking Fitoverm with food, the insect paralyzes irreversibly, and then it simply dies of hunger and dehydration. Spray raspberries during the growing season.
Advantages:
- bio-based and the ability to completely decompose in open space within 1-2 days;
- can be used during fruiting, but not earlier than 3 days before harvest. This is especially valuable for remontant raspberries, in which the fruiting period is greatly extended.
This insecticide with the active ingredient malathion was discovered in the 1950s. It can be sold in a package with the name "Karbofos", and is also included in such products from different manufacturers as Alatar, Antiklesh, Atkellik, Inta-CM, Iskra-M, Phenaksin-plus, Fufanon-nova. It's easier to say: all drugs based on the active ingredient malathion are similar to Karbofos. They are available in a variety of types:
- tablets,
- powders,
- granules,
- solutions.
They have different concentrations, different additives and color. The method of use of each drug is indicated in the instructions.
Karbofos can be sold as a ready-to-use solution
Advantages:
- immediately guaranteed to destroy not only any harmful insect, but also its larvae and eggs;
- low hazard, belongs to the 3rd hazard class;
- when spraying, you need to hit the insect. Sitting on the back of the sheet or missed pests can survive.
Malathion completely decomposes after 7 days in the greenhouse, on open plants and in the ground - after 7-10 days. At the same time, in 7 days, it is completely removed from the plant. Raspberries are treated with this remedy twice:
- the first time in the spring, in the period from bud swelling to budding;
- the second time - after the harvest.
This is a complex drug that has a triple effect: an insecticide, a herbicide and a fungicide, that is, with its help they fight against insects, diseases and even weeds. It is sold, as a rule, in the form of a dark brown paste, it smells of carbolic acid. Very dangerous for humans and animals, according to the classification of the World Health Organization, since 1996 it belongs to class 1A (extremely dangerous). Banned for use in some European countries. In Russia, it is used in industrial conditions with strict observance of safety standards. For this reason, it may not be available for free sale for personal plots, only in specialized firms working with large farms.
Processing is carried out in early spring, as the opened Nitrafen leaf can burn. Use a 2% solution, that is, 200 g of the drug per 10 liters of water. It destroys absolutely all wintering pests, their larvae and eggs, as well as lichens, spotting, fungal spores, all pathogenic microflora.
Nitrafen is very dangerous for humans and animals, therefore it is used only in large farms with strict dosage compliance.
Non-chemical processing of raspberries
This is a one-time job, it can be considered a general treatment against pests, and against fungi and viruses. When sap flow has not yet begun, at the end of winter or early spring, raspberry bushes are watered with boiling water from a garden watering can. This method is also used for other bush plants - currants, gooseberries. Perhaps it would be used for large fruit trees, but it is impossible to do it manually.
This treatment destroys all pests wintering in the buds and under the bush, disinfects viral colonies and destroys spores of pathogenic molds and fungi.
Sometimes, to enhance the effect, manganese is added to boiling water to a slightly pink concentration or a tablespoon of copper or iron sulfate.
In Europe, instead of watering with boiling water, treatment with a solution of birch tar is widespread, since plants in warm climates are not cooled so much and can easily be damaged by too hot water. This procedure is carried out to protect plants from the raspberry-strawberry weevil until buds appear (2 tablespoons of tar per 10 liters of water).
Raspberries are treated with a solution of birch tar until buds appear.
Further treatment with any preparations is performed before the first flower buds appear, but no later than 5–7 days before they open, that is, before flowering begins.
Processing remontant raspberries
From the beginning of budding to harvest, raspberries cannot be treated with chemical insecticides. This complicates the care of remontant raspberries, which bear fruit continuously. In addition, pests can begin to multiply rapidly during fruiting on ordinary raspberries, and it will be impossible to wait. In such cases, it is possible to use not chemical insecticides, but biological means of control that are harmless to humans. For example, the drug Fitoverm described above. All recommendations for its use are in the instructions.
Treatment of raspberry diseases
Raspberry disease control is much more difficult than pest control. Insects can be seen visually, their disappearance is also under obvious control. Spores of pathogenic fungi and viruses are not visible without a microscope, their appearance can only be determined by already developing symptoms. Raspberries suffer from fungal and viral diseases.
fungal diseases
Diseases caused by pathogenic fungi include:
- gray rot - the first sign is the appearance of a grayish coating on young leaves, flowers and buds;
- verticella wilt, or verticella wilt - manifests itself in yellowing and wilting of leaves starting from the bottom;
- rust - it is black or orange, manifests itself in the form of formations on the underside of the sheet;
- septoria, or white spotting - light brown small spots appear on raspberry leaves;
- anthracnose - appears as white spots with a bright red tint on different parts of the plant;
- powdery mildew - can be recognized by a whitish coating on the leaves, from which they fade;
- didimela, or purple spotting - purple spots form on the leaves, from which the leaves crack and dry.
Photo gallery: signs of some fungal diseases of raspberries
With didimel, dark spots form on raspberry leaves. 
Raspberry anthracnose appears as light spots with bright red edges. 
As a result of verticella wilt, raspberry yields are reduced. 
As a result of the defeat of raspberries with powdery mildew, a whitish coating appears on the leaves.
The principle of action of different drugs is very different. Some of them simply poison or burn the fungus colony:
- iron vitriol (sprayed in early spring in the amount of 30 g per 10 liters of water);
- copper sulphate in its pure form or as part of Bordeaux liquid (sprayed in early spring before bud break with a 3–4% solution);
- manganese solution (2%);
- boiling water in spring.
They must be deadly for pathogenic flora and harmless to plants and humans. As a rule, these remedies help at the initial stages of the development of the disease, when harmful colonies are still on the surface of the plant. Penconazole preparations (Topaz) can help with deeper damage.
The drug is considered harmless due to the scanty concentration of the active substance in the solution (treatment is carried out with a solution of 0.2 mg of penconazole per 10 liters of water, for this, a 2 mg ampoule, in which the active substance is diluted in a ratio of 1:10, in turn is diluted in 10 liters water). This is enough to protect the plant for at least 2-3 weeks.
You can process the bushes both in the spring and beyond, but in any case, according to the instructions for use. Topaz works in 3-4 hours. If after this time it rains, this will not stop the effect of the drug - it will have time to be absorbed into the plant.
Topaz protects raspberries even after rain
Horus
This is a modern drug developed by the Swiss company Syngenta. It protects raspberries from all known fungal diseases, but it is important to observe the terms of application. Horus is inactive in the juices of the plant, will not be able to penetrate and work on adult rough foliage. Therefore, it is used only in the spring, when the first buds have already opened into a leaf, and the last ones have begun to open. Then Horus is guaranteed to work as a prophylactic and cure the plant if the fungus has already settled on it. Horus will not be able to cure a heavily infected plant with rough foliage towards the middle of summer and later.
The use of the drug requires careful fulfillment of all the conditions described in the instructions. Raspberries can be harvested if the treatment was carried out 30 days before the berries were harvested: then Horus will be completely removed from the plant.
Chorus is sprayed only on young raspberry leaves.
Viral diseases
This is a much more dangerous type of disease. In the developed stage, there are no funds from them. The foliage becomes mottled or rashed, and the stems become visibly deformed, ugly, and discolored.
The most common viral diseases of raspberries:
- curliness - raspberry leaves affected by the curliness virus wrinkle, turn yellow, become dry and brittle;
- mosaic - appears as light green spots on raspberry leaves;
- streak (viral striation) - leaf plates are twisted close to the stem;
- growth - a lot of thin, undersized, non-fruiting shoots grow on a raspberry bush;
- infectious chlorosis - raspberry leaves turn yellow first between the veins, then as a whole;
- bacterial root cancer - tumors appear on the roots of raspberries, at first they are soft, then harden, and the roots die off.
Photo gallery: some viral diseases of raspberries
Raspberry leaves affected by the curl virus wrinkle, turn yellow, become dry and brittle 
Mosaic is more likely to affect raspberries in wet, cool weather. 
Raspberry chlorosis is transmitted by aphids
With all viral diseases, if the bush is completely affected, it is dug up and burned without hesitation. Raspberries have not been planted in this place for 10 years. However, here you can make a mistake, the same symptoms may appear for other reasons. If the disease is just beginning to develop, and the price of the issue is too high, it is better to invite a specialist so that he can make an accurate diagnosis on the spot.
To prevent the spread of infection in the garden, the following preventive measures are taken:
- the fight against harmful insects that carry infections;
- treatment of bushes with copper-containing preparations such as Hom, Oksikh, 1% Bordeaux liquid.
Folk remedies for processing raspberries from pests and diseases
For adherents of environmentally friendly methods, folk remedies for processing raspberries are well suited. For example, it is possible to recommend a composition that is universal for the protection of many plants. For 10 liters of water take:
- 1 liter of any fermented milk products (whey from sour milk, kefir, fermented baked milk);
- 1 teaspoon of iodine pharmacy tincture - for prevention, or 1 tablespoon of iodine - for treatment.
This is not a panacea, but a very powerful tool for the prevention and treatment of fungal, viral infections, as well as insects with sensitive skin. An acidic environment is unsuitable for the development of viruses and fungi, and iodine and alcohol sterilize them. Milky solutions cover the surface of the plant well and adhere to it like a soapy emulsion, which provides a longer-term effect and protection. The same composition is recommended to water the root circle. There is no harm from it, on the contrary, with a lack of iodine in the soil as a trace element for plants, it can serve as top dressing. It is also useful for plants and the background of lactic acid bacteria.
With a lack of iodine in the soil as a trace element for plants, it can serve as top dressing
Another remedy for powdery mildew and some other fungal diseases is a solution of 1 teaspoon of salt in 200 g of milk. It works simply - the fungus dehydrates and dries. The disadvantage of this method is that the treatment must be carried out 2-3 times with an interval of 2-3 days. Salt solution should also not be allowed to enter the ground: you need to handle it carefully or lay something under a bush.
Against aphids, a highly concentrated solution of a well-known fertilizer, urea urea, can be recommended.. If a concentration of 40–50 g per 10 l of water is used for top dressing, then for pest control the concentration is 12–14 times higher - 500–700 g per 10 l of water. This remedy is used against all wintering pests, as well as against some viral diseases: scab, all types of spotting, rust. The solution is treated with the bushes themselves and leaf litter. Sprayed both in the fall in the first stage of leaf fall, and in the spring before the leaves bloom. But keep in mind that such a concentration can harm young tender foliage. Along the way, it should be taken into account that raspberries are already fed with nitrogen - up to 46% in urea.
Fungi, viruses and insects may not like other folk remedies:
- mustard powder,
- infusion of celandine,
- tobacco infusion,
- wormwood infusion,
- infusion of garlic.
However, there is no reason to guarantee their effectiveness.. There is an experience of gardeners who have been cultivating a garden for many years under the slogan "no chemistry". And then they had to uproot the affected trunks and bushes and plant a new garden.
Elimination of anthills
In the spring, immediately when the first leaves appear, aphids can cause great harm to raspberries. There are many varieties of these insects. You can easily get rid of most of them even with a one-time treatment with folk remedies or chemicals, which were discussed above. But more persistently, raspberries can be attacked by aphids, which are spread by ants. Ants breed and even protect this type of aphids from predatory insects (wasps, ladybugs, some types of flies) and then use their metabolic products as a food base. After treatments, ants can again repeatedly populate raspberries with aphids.
You can not leave anthills near raspberries, as ants spread aphids
Therefore, you need to make sure that there is not a single anthill next to the raspberry. This is a very simple operation if it is not under the roots. You need to do the following:
- Dig up soil with an anthill.
- Place it in water, airtight container.
- After the insects have died, remove the anthill at a great distance from the garden.
If the anthill is located directly under the roots of a raspberry bush, the plant may soon die. Since it is impossible to dig out an anthill due to the proximity of the roots, it is enough to fill it in:
- steep boiling water once or repeatedly with ordinary water, simply by making a puddle in place of the anthill;
- ammonium nitrate solution in the proportion of 500 g per 10 liters of water.
You can use recommended insecticides and other products that are incompatible with the habitat of the ants. Sometimes it is enough to cover the trunk circle or anthill with a layer of ammonium nitrate, nitroammophosphate or diammophos. The main rule is not to poison the earth with too toxic drugs. The product must be harmful to the ants and harmless or even beneficial to the soil.
Competent agricultural technology is the best means of preventing raspberry diseases and pest invasion
In favorable conditions, raspberries develop healthy and strong, able to withstand most misfortunes. Therefore, proper planting and competent care for it are important as a prevention of diseases and the appearance of pests. The following rules must be observed:
Spring is a favorable time for arranging a plot with raspberries. Regardless of the variety, it must be protected from diseases and pests, cut, fed, watered. Only with good care, raspberries please with a plentiful and tasty harvest.
When to process raspberries in spring
Bushes are processed at the beginning of the growing season and during budding (5-7 days before flowering).
During the flowering of raspberries, any preventive or therapeutic measures should be excluded. The processing of bushes during this period leads to the death of pollinating insects and, as a result, to a deterioration in the yield.
What to process
Processing is carried out both with chemical preparations (urea, copper sulfate, dolomite flour, Bordeaux liquid), and folk remedies (mustard, soda, boiling water, infusions of herbs and flowers).
To strengthen the plants, urea treatment is performed in early spring. 15-20 grams are taken per square meter. Urea saturates the bushes with nitrogen and makes them less susceptible to disease.
Processing raspberries with copper sulfate avoids the appearance of fungal diseases (gray rot, anthracnose). Raspberry stalks and the soil around the bushes are processed. For spraying, 50 grams of vitriol is taken per 5 liters of water.
During the growing season and during the active growth of the plant, treatment with copper sulphate cannot be performed. It accumulates in berries and stems.
In the fight against anthracnose, rust and powdery mildew, the treatment of bushes with a 1% solution of Bordeaux liquid or ferrous sulfate, Topaz, Nitrofen helps.
The main reasons for the development of infections are high humidity and high acidity of the soil. Reducing watering reduces moisture. Acidity can be reduced with wood ash, slaked lime, dolomite flour. 150 grams are taken per square meter.
Mustard protects raspberries from weevil larvae.
For spraying, 20 grams of dry mustard is taken per 10 liters of water, everything is mixed and infused for 12 hours. Spraying of bushes is carried out in several visits.
Instead of mustard, you can take baking soda, 2 tablespoons should be diluted in 10 liters of water.
Processing the bushes and the root circle with boiling water allows you to get rid of most pests. The procedure is performed after the snow melts and the soil warms up.
With a small area of damage, raspberry beetle larvae can be harvested by hand. Before flowering, it is treated with an infusion of bitter wormwood and marigolds. When using Agravertin and Agravertin, the treatment is performed twice.
During budding, raspberries can be sprayed with tansy infusion.
For infusion, 350 grams of dry grass or a kilogram of freshly harvested raw materials, 5 liters of water are taken. Tansy is infused for a day, then boiled for half an hour, filtered and diluted with the same amount of water.
Mulching with pine needles protects against weevil and gray rot.

The main pests and diseases of raspberries with photos, descriptions and control measures
Pests
The main pests of raspberries are:
- stem gall,
- raspberry beetle,
- stem fly,
- weevil,
- spider mite,
- kidney moth,
- raspberry nutcracker,
- raspberry glass.
stem gall midge
The presence of swellings on the stems and shoots of raspberries indicates that the plant is affected by stem gall midge. Such shoots are cut and burned.
For prevention in early spring, the soil is loosened to a depth of 5-10 centimeters and sprayed with karbofos or Fufanon.
During the appearance of buds, re-treatment with Fufanon or Actellik is performed.
Aphids feed on plant sap and accumulate on the lower part of the foliage. To destroy the pest during bud break, karbofos or Actellik is used.
stem fly
For the prevention of stem flies, mulching the soil around the bushes is used. Mulch makes it difficult for insects to get out of the ground. The first treatment is carried out after the snow melts, karbofos is used. In early May (before flowering), Fitoverm, Aktellik or Agravertin are processed.
Raspberry Nutcracker
Raspberry nutcracker attacks raspberry stems. The larvae feed on stem tissue and cause tissue cracking and swelling. Blisters in length reach 10 centimeters. Diseased plants are removed from the site. For the prevention of healthy bushes, treatment with karbofos is carried out.
Weevil
When raspberry bushes are affected by the weevil, the plants are treated with karbofos, metaphos or Actellik. Processing is done a week before flowering.
kidney moth
To combat the kidney moth in early spring (before the buds swell), the bushes are treated with Bordeaux liquid, Confidor, Spark, Decis. When leaves appear, a 10% solution of karbofos is used.
raspberry beetle
The raspberry beetle damages the leaves, buds and berries of the plant. Berries shrink and quickly deteriorate.
To protect against the raspberry beetle, the bushes and the ground around (immediately after the snow melts, pruning and tying the bushes) are sprayed with a 10% solution of karbofos, Nitrafen, Decis, Confidor, Iskra and covered with mulch.
Raspberry glass
When a raspberry glass case appears, the damaged stems are cut and burned, the caterpillars damage the stems, roots and lead to the weakening and death of the bushes.
spider mite
Spider mites can be identified by white punctures on the surface of raspberry leaves. With a strong defeat, the plants begin to wither and die.
In the fight against spider mites, karbofos, phosphamide, metaphos, colloidal sulfur, Cidial are used. Spraying is done in the evening.
Diseases and pests of currant. Processing in the spring
Diseases
Raspberry is amazed
- anthracnose,
- rust,
- white and purple spotting,
- powdery mildew,
- vercillo wilt,
- gray rot,
- streak,
- mosaic,
- mycoplasma disease (growth),
- curly,
- chlorosis,
- bactericidal root cancer,
- root rot.
Anthracnose
Anthracnose (leaf curling) occurs when there is a lack of boron or potassium in the soil. With a lack of potassium, the leaves are wrapped inside. You can correct the situation with the help of ash. The lack of boron can be compensated by adding a solution of boric acid.
From gray rot and anthracnose, raspberries are treated with Nitrafen solution in early spring. When buds open, Bordeaux liquid is sprayed. Fitosporin can be used at any time.
With the appearance of mottling, stains, spotting on the leaves (viral diseases), they must be removed immediately. Pruning old shoots, thinning and feeding plants avoids these diseases. 
To avoid verticillium wilt when planting, the roots should be dipped for 10 minutes in a weak solution of potassium permanganate. When leaf spot appears, Bordeaux liquid is used.
verticillium wilt
Raspberry Chlorosis
Pests (mites, aphids, nematodes) penetrate the stems through cuts, breaks. These insects are carriers of viral diseases (chlorosis, jaundice). The leaves turn yellow, the stems are depleted, the berries become smaller and dry quickly.
At the first sign of chlorosis, plants need to be dug up and burned, healthy bushes and the soil around are treated with protective preparations.
Mycoplasma disease
Mycoplasma disease leads to the formation of a large number of infertile thin shoots from 30-50 centimeters long (about 200 pieces per bush). At the first manifestations of the disease, the bush is dug up and removed from the site.
Root goiter and root cancer leads to yellowing of the foliage. When transplanting or planting bushes, you need to pay attention to the roots. If there is swelling, they are removed, and the cuts are treated with a 1% solution of copper sulphate. 
leaf curl
When raspberry curl appears, the leaves become very small, become wrinkled, hard. The underside of the leaves turns brown. Berries become sour, deformed and dry. The plant dies within 3 years. Sick bushes are immediately removed and sent to the fire.

Raspberry care
In addition to processing raspberries from pests and diseases, care includes:
- pruning,
- top dressing,
- tying,
- watering and weeding.
To prevent raspberry bushes from getting sick, you need roots and stems from mechanical damage. Shrubs in one place can grow no more than 7 years. They can be planted on the former site after 4 years.
Landing should be done in fertilized soil. Seedlings should be healthy, strong, with a well-developed, powerful root system, without any damage.
Treatment with copper-containing preparations (1% Bordeaux liquid, Oksihom, Abiga-Peak, Hom, Copper oxychloride) saves raspberries from infections. In rainy weather, spraying should be repeated after 1.5-2 weeks.
To combat diseases of raspberry bushes, it is necessary to provide plants with a high level of agricultural technology (the right place for planting, top dressing, timely watering, loosening, weeding, tying and mulching).
If the raspberries dry out, then there are reasons for this: lack of nitrogen, lack of moisture and thickening of the planting. Eliminating problems can improve the yield several times over.
How to prune raspberries in spring
Pruning is done from the second year of plant life.
One of the more important steps in caring for raspberries is pruning.
First of all, shoots are cut off on which fruits are not expected (frozen, damaged and young), they are cut off at the root. If the shoot is partially damaged, it is cut to a healthy place.
Regardless of the planting, the bushes should not be thickened. With a bush form, 8-12 stems should grow, with a ribbon no more than 25 stems.
The second pruning is done when the raspberries grow.
The tops of raspberries are cut to 12-15 centimeters (to the first bud), this stimulates the development of the plant and lateral buds. The height of the stem should not exceed 1.5 meters.
How to fertilize raspberries
The most necessary useful substances for raspberries are potassium, phosphorus, nitrogen and organic matter.
- Potassium improves the yield and winter hardiness of plants.
- Phosphorus strengthens shoots.
- Nitrogen accelerates plant growth. Any raspberry variety gives a good harvest on soil rich in organic matter.
To increase the yield, spring dressing is carried out in several stages.
Any kind of raspberry dressing is done after watering and loosening the soil.
For the first top dressing, after the snow melts (before loosening the soil), urea or saltpeter is used. Granular fertilizer is applied under the bush immediately after watering. 15 grams of saltpeter or 20 grams of urea are taken per square meter. To enhance the effect, a glass of wood ash is scattered under the bush.
After loosening the land, rotted manure, peat or compost is distributed on the site. The organics will serve as mulch.
In May, raspberries need to be fed with mullein. The mullein is filled with water in a ratio of one to one and infused for a week. The resulting infusion is diluted with cool water (2 liters per 10 liters of water), poured under the bushes.
When laying the ovary, top dressing is carried out with superphosphate. After this procedure, the bushes become strong, resistant to diseases, the yield increases.
During flowering, 1 glass of superphosphate, a glass of ash and 100 grams of carbamide are introduced.
The mixture is diluted in a bucket of water and spilled under the bushes.
Feeding raspberries with chicken manure increases the yield and strengthens the plants. Litter is diluted in water in a ratio of one to five and infused for 5 days. The finished infusion is diluted one to twenty and used for its intended purpose.
Raspberry. The fight for the harvest begins in the spring: video
Proper processing of raspberries in the spring and good care allows you to get a bountiful harvest every year.
The snow has not yet melted, and summer residents are already working on their plots, preparing crops for the new season. Spring care is not complete without mandatory pruning, but you still need to feed the plants and spray with protective agents. Only the right approach will ensure a good harvest.
Why is shrub processing necessary?
Those who already have a dacha know that farming is not only an entertaining pastime, but also painstaking work. Even with proper agricultural practices, garden shrubs get sick and are attacked by insects. Neither top dressing nor sanitary pruning will save the situation if raspberries are not processed in the spring from diseases and pests.
Horticultural crops are still weakened after hibernation, and insects, smelling the spring warmth, are already beginning to crawl out of the ground or fallen leaves in autumn to feed on raspberry shoots, in which sap flow has begun.
Note! Preventive spring spraying of bushes will allow you to fertilize plants in parallel, thereby increasing their immunity. If fungal spores enter the site, or diseases associated with violations of agricultural technology develop, after treatment it will be easier for plants to resist such problems.
Raspberry processing
Diseases and pests of shrubs
Raspberries are subject to diseases that affect other garden plants. Some of them are associated with care errors, others are fungal, bacterial, viral in nature. Insects do not bypass the shrub, which first feast on the stems, then the buds, leaves, gnaw out the buds. If you do not take the necessary measures, they get to the fruits.
Raspberry diseases
The infection can get to the site with new seedlings that have appeared in the garden, pests that have arrived, or be carried by the wind. If currants grow next to raspberries, the bushes begin to hurt at the same time.
Raspberry and currant
Ordinary raspberry varieties are weakly resistant to infections. The remontant species and new hybrids have great immunity, but if they are not sprinkled in the spring or stop caring for them, then these varieties will quickly get sick.
The main diseases of the raspberry
| Infection | Short description |
|---|---|
| Viral diseases | |
| Mosaic | Light, sharply defined marks are formed on the leaves, gradually merging into rings. In the process, the plates turn pale, then turn yellow and become covered with necrotic spots. If the virus appears at the time of flowering, on the petals you can see dashed, elongated, small spots that differ in shade |
| Chlorosis | Pests, penetrating into breaks and cuts on the stems, infect the plant with a virus, causing the shoots to turn yellow and thin. Gradually the whole bush dries up |
| Curly | This disease affects the plant slowly - over 2-3 years. The leaves shrink, wrinkle, become stiff. The plate below acquires a brown tint. The bush is deformed, gradually dries. Berries lose their taste value |
| Bacterial | |
| Septoria | The leaves are covered with brown-purple spots, which later turn gray. At the same time, the edges are lighter than the core, on which you can see tiny black dots |
| Rot wet | The leaves begin to turn yellow from the tips, then the entire plate changes color. Further, dark gray or brownish wet spots appear. Very quickly, the infection spreads to the stems, penetrating into the core. If the flowers have had time to bloom, they fall off. The disease is characterized by a sharp unpleasant odor |
| Crayfish | The disease creeps up unnoticed, so it is difficult to understand when the kidneys die. The problem is indicated at the time of budding - too few flowers are formed. Even those that managed to open up quickly turn black and dry. You can also notice cancerous growths on the shoots. |
| fungal diseases | |
| Rot gray | The leaves turn yellow completely, and black small dry spots appear on the underside of the plate. The shoots are covered with a fluffy ash-gray bloom, which can be seen in the future on the fruits. |
| spotting | First, spots of gray, brown or black appear on the leaves. Sometimes they have a border or dotted with small dots. Gradually, the leaves turn yellow, die and crumble. The bush is delayed in development and loses its decorative effect. Most often, the disease is associated with malnutrition. |
| Rust | Yellowish spots on the leaves begin to darken, becoming like metallic rust. Dusty yellow pads form on the underside of the plate, which turn into black stripes by the end of the season. |
| Anthracnose | The onset of the disease is characterized by dark red or grayish-purple rounded spots covering the leaves and stems. Along the contour, you can see a spotted edging. Leaf tissue engulfed by spores becomes brittle and may fall out. Stems ulcerate with wounds, then turn brown and dry out |
| Powdery mildew | On the shoots and leaves, you can see a powdery coating in the form of a web. The mushroom picker grows, forming small balls that darken over time. The tissues affected by the plaque turn yellow, dry out, the leaves fall off |
Important! If you do not notice the development of diseases in time and do not take the necessary measures, you can not only lose most of the crop, but also destroy the entire plantation.
Pests
Most insects are very small, and it is difficult to immediately detect them on a raspberry tree. Many pests live in the soil, eating up the roots, or settle inside the shoots, buds and penetrate into the berries. Therefore, it is very problematic to deal with them, not knowing the main signs of an invasion.
Raspberry pests
| Name | signs |
|---|---|
| gall midge | The appearance of an insect that has penetrated inside the stems can be judged by the ugly swellings that appeared on the shoots. |
| Weevil | With its long proboscis, the pest pierces the tissues of the plant and sucks out the juices. Exhausted shoots wither, leaves fall off. If the weevil gets to the berries, they dry out |
| crimson beetle | It feeds on leaves, flowers and berries. The fruits quickly deteriorate and shrink |
| spider mite | Its presence can be recognized by the white punctures that appear on the leaves. If the bush is significantly affected, it quickly withers and dies. |
| stem fly | The insect sucks juices from the shoots, causing the tops of the stems to wither and droop. |
| Raspberry hazelnut | Pests feed on shoots, causing them to crack. On the stems at the site of tissue damage, you can see 10-centimeter swellings |
| Aphid | These small green insects are immediately visible - they stick around the stems and leaves with whole colonies. Penetrates into unopened buds |
When to treat for pests and diseases. Despite their small size, pests very quickly infect raspberries. If you do not take preventive measures and do not fight them, the berry plant will start to get sick and lose its grade. In some cases, the affected bushes will even have to be removed so that they do not infect other crops in the garden.
The main preventive measures are carried out in early spring, treating the bushes with special preparations. It is necessary to spray raspberries several times throughout the season at intervals of 2-3 weeks, since each pest has its own periods of activity.
Chemical preparations can be used until the beginning of budding. As soon as the abundant color goes, only folk harmless remedies are used. It is necessary to process not only the bush, but also the soil around it.
Raspberry blossom
At the same time (from March until the buds swell), poorly overwintered shoots should be cut off: frozen, diseased, damaged.
Note! Together with the preventive treatment of the berry, feeding is carried out. Fertilizers contain substances that can neutralize insect larvae and prevent fungal spores from multiplying.
What to process
In order for the fight against diseases and pests to be effective, you need to know how to process raspberries. It is recommended not to be limited to one tool, but to apply the whole complex. These are various preparations of industrial production and folk methods. As an alternative to chemical compounds, manufacturers offer a selection of biological products that are harmless to humans, but effectively cope with diseases and insects.
Some substances have a narrow specialization, others have a broad action:
- Bordeaux liquid (and analogues) can be safely used against diseases and insects;
- acaricides are designed to control ticks;
- insecticides affect all pests;
- systemic fungicides are used against the fungus.
Biological agents
A good result in the care of raspberries is given by biological products, which can be safely called an environmentally friendly product. The composition includes live bacteria, viruses and antagonist fungi that do not harm plants, but help to destroy pathogenic insects and diseases. Each such remedy not only heals the berries, but is also an excellent top dressing.
Note! Biological preparations dissolve well in groundwater, so they can be incorporated into the soil dry.
Chemical substances
These products contain pesticides, so they are resorted to as a last resort, if the biological ones did not give the desired result. But before you start processing raspberries in the spring from pests and diseases, it is recommended to cut off the already affected areas of the bushes and destroy them. It is better to make do with a small sacrifice in order to save the rest of the plant.
Chemistry is used repeatedly - you will have to carry out at least 4 treatments (2 of them are spring):
- at an early stage of the growing season, when the leaves hatch from the buds;
- before the bush blooms;
- after they harvest (for remontants - after the second wave);
- 2 weeks from the previous spraying.
To combat raspberry pests, it is better to use universal broad-based means:
- Karbofos, produced in the form of a concentrate (30%);
- Chlorophos on sale is represented by 2 options: in powder and technical form (both 80 percent);
- Trichlormetafos-3 - 50% emulsion;
- Decis, Fury, Fufafon, Taran - in ampoules.
Karbofos
To combat spider mites, Acaricide is suitable, Formalin will help get rid of the larvae. The rules for using chemicals are indicated on the packaging, these instructions must be followed.
Chemicals against raspberry diseases
| A drug | Mode of application | From what diseases |
|---|---|---|
| Euparen and Benlat | Every 3-5 days, raspberries are sprayed with a 0.2% solution until the plaque disappears. | Against gray mold |
| Cuprozan | Periodic treatment of bushes with a 0.4% solution | Spotting protection |
| SCOR, Vectra, Topaz, Nitrafen | Ampoules of 2 ml are diluted according to the attached instructions | To combat powdery mildew and gray mold. Often used against rust, oidium and other typical diseases. |
| Iron and copper sulfate | Powder or crystalline salt is diluted to 4-5% just before spraying raspberry bushes | From all types of bacterial and fungal diseases |
| Keltan | 0.2% solution is used for watering plants | Good not only in the fight against fungi, but also against some pests |
| Oksikhom | The properties are similar to copper oxychloride. 1 sachet of 10 g is designed for 5 liters of water | Universal remedy |
| Phthalan | An analogue of Bordeaux liquid, diluted at the rate of 40 g per 1 liter of water | Against all fungal diseases |
| figon | For spraying raspberries, a 0.2% solution is required. | |
| Fundazol | Systemic fungicide. It is used not only for the treatment of the disease that has arisen, but also for prevention; | |
| In the first case, it is taken in the proportion of 0.15-0.2%, in the second - 0.05-0.1% |
Folk recipes
Important! When using pesticides, precautions must be taken. Each of the described means is dangerous for humans.
folk therapy
| Means | How to apply | From what problem |
|---|---|---|
| Marigold | 0.5 buckets of dry leaves are soaked in 10 liters of hot water and kept for 2 days | Against fungal diseases and aphids |
| Mustard | Take 10 g of powder in a bucket of hot water and leave for 2 days, then dilute, increasing the volume by 2 times | Raspberry pest control |
| wood ash | 3 g. funds are poured with a bucket of boiled water and after 2 days they process not only the bushes, but also the near-stem circle of the earth | Good for powdery mildew treatment and pest control |
| Mullein or rotted hay | A third of the bucket is filled with water (3 l) and insisted for 3 days. Then filter and add water to the 10-liter bucket to the top. | · From all types of diseases of the berries; |
| This product is also an excellent fertilizer for the plantation | ||
| Garlic (onion) | · Scroll in a meat grinder and fill with water (100 g per 5 l). After 2 days, the bushes are treated; | Its smell repels almost all pests |
| Experienced summer residents recommend periodically just sticking a clove of garlic into the ground next to the bush | ||
| horsetail | Fresh grass (300 g) is soaked in cold water (3 l) for a day. Then bring to a boil and simmer for half an hour over low heat. After cooling, filter and dilute in a ratio of 1:5. It is necessary to spray a diseased plant at intervals of 1 time per week until the disease subsides. | Used against powdery mildew |
| Iodine | A bottle of the product is dissolved in a liter of water and the diseased bushes are sprayed | From powdery mildew and for preventive purposes |
| Alcohol ammonia | 3 tbsp bred in a bucket of water. With this composition, they try to water raspberries in the early spring in order to disinfect and prevent the disease. One bucket is enough for 2 adult bushes | From all fungal and bacterial diseases |
There are many homemade recipes for coping with raspberry problems in the arsenal of summer residents. Each folk version is good, and some gardeners manage to do just a little - they use ordinary boiling water. After waiting for the snow to melt and the soil to thaw a little, they water the bushes and the near-stem circle with such water, thereby destroying the pest larvae that wintered in the raspberries.
After such a treatment, urea is also used, it is scattered on both sides of the raspberry row. At the same time, the summer resident solves 3 problems at once: the drug will feed the bushes, strengthen immunity against diseases and protect against pests.
Mistakes in agricultural technology
Inexperienced farmers sometimes make mistakes in caring for raspberries:
- starting to fertilize the bushes, they try to use as many nutrients as possible, hoping that the amount will give a good result;
- another wrong entry in agricultural technology is frequent watering of plants with solutions supplemented with fertilizers;
- the terms for processing raspberries are not always kept - sometimes this happens at the time of ripening of the berries;
- forget to cut off diseased, damaged and old shoots.
These and similar errors weaken the plants, which provokes the defeat of diseases. Only by learning how to properly care for crops, you can get good harvests. Spring work in the garden is especially important, as a guarantee of plant health.
