One of the main factors hindering the full development of raspberries is the negative impact on the plant of diseases and pests. Most of them are able to destroy most of the crop and / or significantly reduce its quality. You can fight against them in autumn, spring and at any other time of the year. Competently combining chemical and agrotechnical methods of combating diseases and pests, it is quite possible to achieve their destruction or a significant reduction in the harm produced.

Spring processing time
Application chemicals on raspberries for various purposes is carried out in the first days of the growing season and in the budding phase. A week before the start of flowering, processing is completed.
Until flowering is complete, the use of chemicals on raspberries is prohibited. It leads to the death of pollinating insects, as a result of which the yield and its quality are sharply reduced.
Processing currants from pests and diseases - how to spray the bushes in the fall?
Preparations for treatment
It is allowed to use both conventional chemicals and folk remedies. So, in March, plants are treated with urea at the rate of 20 g of liquid per 1 sq. m. This tool helps to saturate raspberries with nitrogen and increase resistance to diseases.
To prevent anthracnose, gray rot and other fungal diseases, raspberries are sprayed with copper sulfate. Both the stems and the near-stem sector are processed. The dosage of the drug is 50 g / 5 l of water. It is not recommended to carry out the treatment with the described agent during the period when raspberries enter the period of active growth and development, since the residual substances of copper sulphate have the ability to accumulate in stems and fruits.
Bordeaux liquid or iron sulfate is actively used on raspberries to resist powdery mildew, rust and anthracnose. It is allowed to use specialized drugs like "Nitrofen" and "Topaz". Use them according to the instructions for the tool.
Infectious diseases most often develop due to unsuitable growing conditions. Usually these include waterlogged or excessively acidic soil. The first problem is eliminated by reducing the intensity of irrigation, and alkalization of the soil is carried out using dolomite flour, slaked lime, wood ash and other similar preparations. On average, per 1 sq. m of soil is introduced about 150 g of the substance.
The simplest folk remedy for spring care behind raspberries is the usual boiling water, which is poured over the stems and stem circles. Thanks to this action, you can get rid of the vast majority of pests. This agricultural technique is carried out after the snow has completely melted and the earth has warmed up sufficiently.
The most common folk remedy for protecting raspberries from pests is mustard. It is widely used in the fight against weevil larvae. 20 g of mustard powder is diluted in 10 liters of water. The resulting solution is infused for 12 hours. The treatment is repeated several times. In the absence of mustard, 2 tablespoons of baking soda are allowed.
Before the start of the growing season, shortly before the flowers bloom and after harvesting, the plants are usually sprayed with ammonia. This procedure contributes both to protection against diseases and pests, and to the saturation of the plant with nitrogen.
Before the onset of the flowering phase, a solution of marigolds and bitter wormwood is prepared. It is used for treatment against crimson beetle larvae. For the same purpose, drugs like Agrivertin are used, which are sprayed twice. With a small area affected by larvae, manual collection of insects is also allowed.
When budding occurs, it is worth using a decoction of tansy;
- 1 kg of freshly harvested grass or 350 g of dried raw material is poured into 5 liters of water;
- the mixture is boiled for 30 minutes and infused for a day;
- the resulting solution is filtered through a sieve or gauze and diluted in another 5 liters of water.
Control of diseases and pests in autumn
When the last picking of berries is completed, the bushes for pest protection are treated with a Fufanon solution at the rate of 10 ml per 10 liters of water. For each raspberry bush, there should be about 1-1.5 liters of the resulting solution.
Instead of Fufanon, the following drugs are allowed:
- 1. "Intavir" (1 tablet dissolves in 10 liters of water);
- 2. "Aktellik" (1 ampoule with a volume of 2 ml is diluted in 2 liters of water; 1.5 liters of the resulting liquid is consumed per 10 square meters of soil).
Before the onset of cold weather, you should get rid of mosses and lichens on the plant. For this purpose, the soil in the trunk sector is watered with iron or copper sulfate.
Treatment of raspberry diseases
The plant is affected by a number of diseases of various nature. Most of them have specific terms and methods of treatment.
Raspberry chlorosis
The carriers of the virus of this serious disease are the following insects:
- nematodes;
- ticks;
- aphids, etc.
These pests penetrate the tissues through wounds and incisions on the surface of the bark of the stems. After infection, the entire leaf blade, except for the veins, acquires a yellow color. Gradually, the sheet completely changes color and is greatly deformed. The stems become long and thin, the quality of the berries is significantly reduced.
Increased irrigation and acid soil reaction contribute to increased infestation. The effect of these factors is offset by a decrease in irrigation and the introduction of gypsum in the proportion of 120 g/1 m 2 . Another indirect method of combating chlorosis is the destruction of insect vectors of the virus. Unfortunately, specialists have still not been able to develop a fungicide to combat this disease, so the affected plant can only be dug up and burned. Re-planting raspberries in this place is allowed only after 10 years.
growth
In the people, this disease is known under the name "witch's broom." It manifests itself in the fact that many barren short (up to 50 cm) shoots are formed on the stems. One bush sometimes has up to 200 such processes.
The site after infection should be checked for the presence of leafhoppers, since these insects are the carriers of the described disease. It is possible that the diseased seedlings were already among the planting material. It is not yet possible to defeat the growth by a chemical method, so the diseased bush must be burned as soon as possible until the disease has passed to neighboring plants.
Rust
This disease is the main cause of drying raspberries. At first, the infection is expressed by the formation of dark spots on the back of the leaves, which gradually dry and fall off. Then the disease moves to the stems, forming brown ulcers there.
Rust is also not treated with chemicals, but it is possible to take preventive measures to prevent infection. To do this, in spring and autumn, the bushes are sprayed with a 1% solution of Bordeaux mixture.
Other reasons that cause raspberries to dry out include:
- crowded landing pattern, causing insufficient lighting;
- arid growing conditions;
- lack of fertilizers, in particular, nitrogen.
powdery mildew
Warm rainy summer is the best condition for the development of this disease. The bush is covered with a white fluffy coating, due to which the berries become smaller and shrivel, and the foliage dries and falls off.
After harvesting, the infected shrub should be processed. To do this, you can use any fungicide used to combat fungal diseases.
Root cancer, root disease, mosaic
Root cancer and root disease have similar symptoms:
- nodule raids appear on the root system;
- the growth and development of the plant is suspended;
- the taste of fruits deteriorates, their sweetness decreases;
- the leaves dry and fall off.
Diseases most often develop on soils with a neutral or alkaline reaction of the environment. Before planting, you should carefully inspect the planting material and pay special attention to the condition of the root system. In the presence of the slightest growths, the diseased part is cut off, and the place of the cut is poured with a 1% solution of copper sulphate.
Another disease, the symptom of which is yellowing of the leaves, is mosaic. The carrier of this viral disease is aphids, so the only way to combat the disease is to destroy insects with chemical means. Affected plants should be immediately removed from the site and burned.
In some cases, the yellowness of the leaves does not signal the development of any disease, but an excessively thickened planting, which prevents the penetration of sunlight and refreshing air masses into the crown. This shortcoming, made when planting seedlings, is corrected by pruning and subsequent feeding of the raspberries with half-rotted manure or bird droppings.
Curly raspberry
The leaves turn brown on the back, deform, become small and harsh. Berries acquire a sour taste, change shape and subsequently dry out.
A fungicide that could defeat this disease has not yet been created. The only measure that can save plants from it is to inspect the planting material for the presence of curl symptoms.
purple spotting
In the scientific literature, the disease is most often referred to as "didimella". Purple small formations are formed on the shoots, which gradually increase, acquiring a dark color along the edges. Black pycnidia form in the center of the affected area. The result of the development of the disease is the absence of kidneys and the breaking of the stem. A factor that increases the spread of the disease is a humid warm summer.
Sick plants should be removed. For prevention, the bushes are treated with a 1% solution of Bordeaux mixture four times per season:
- when young stems reach a length of about 15 cm;
- before flowering;
- after flowering;
- after the completion of the harvest.
Anthracnose
On the shoots and foliage, small spots of gray color with a purple border appear. Gradually, they increase and coalesce with each other, forming large ugly ulcers.
The foliage begins to deform and dry, the berries darken and die, and the bark is separated from the shoots. The fight against anthracnose involves the same methods that are used in the treatment of any other fungal disease.
Ulcerative and autumn spotting of stems
The symptoms of both diseases are almost completely identical to those signs by which dimidella is identified. Diseases are widely distributed in dense raspberry forests that have not been cared for for a long time.
Dried shoots should be removed immediately, as they often become a haven for pests - peddlers of spotting. Stems that are weakened and growing deep into the crown should also be shortened. An effective agricultural practice is sanitary pruning. Of the fungicides, Topaz or Nitrafen should be used.
Raspberry Pest Control
Insects do no less harm to raspberries. The negative effect of many of them usually leads to the death of the plant.
Pest control involves the use of chemical pesticides. They should be used with extreme caution.
spider mite
The pest affects not only raspberries, but also most other berry crops. The insect lives on the back side of the leaf and consumes juices from it, entangling the leaf blades with a thin cobweb. Their coloring becomes less intense, gradually the leaves dry and crumble. Most often, the invasion of ticks occurs during prolonged heat without precipitation.
Most effective tool pest control are chemical treatments with insecticides, which include colloidal sulfur, karbofos, etc. Depending on the extent of the lesion, up to four sprays per season are allowed, between which about one and a half weeks usually pass. It is effective to combine treatments with watering the bushes with ordinary water in the evenings.
Their destruction should be carried out in the budding phase. They can be shaken off the bushes and crushed with your foot. Chemical treatment should also be carried out using preparations like Decis, Confidor, Karbofos, etc. At the end of summer, it is imperative to dig up the soil in the near-stem circle of plants.
kidney moth
The insect is a butterfly with dark red wings, the caterpillar is red with a dark brown head. It harms raspberries in all phases of development. Wintering takes place in wounds and cracks in stems or under foliage in the ground. In the spring, the caterpillars reach the buds on the shoots and eat them away. After that, they penetrate inside the stem and at the end of spring pass into the state of pupae. When flowering begins, pupae have already become butterflies and lay eggs in flowers. Then caterpillars develop from them, destroying ripe berries.
The fight against both types of pests is carried out when the buds begin to bloom. Actellik and Karbofos are used as plant protection chemicals.
Gallica
This pest is also found on raspberries in two forms: shoot (aka raspberry mosquito) and stem gall midges. They lay their eggs in wounds and lesions on the underside of stems. As a result, swellings called galls form in these places. They cause peeling of the bark and death of the stems.
The affected parts of the plant are removed and burned. The soil in the autumn and spring periods is dug up at least 15 cm deep. Chemical treatment is carried out using Actellik or Karbofos.
Similar symptoms are caused by such a pest as raspberry nutworm. The fight against it is similar to the method of destroying gall midges, but before flowering, processing with Ambush is allowed.
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. On the square meter 15-20 grams are taken. 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 pruned 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.
When fighting spider mite 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 leaves. 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 up,
- 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, strong 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
most needed beneficial substances for raspberries is potassium, phosphorus, nitrogen and organics.
- 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 top 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.
Raspberries. 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.
Raspberries are the most common berry crop growing on household plots. Both adults and children love to eat it, both fresh and in pies, compotes, and various desserts. For good raspberry growth, apart from good care, it requires annual treatment for diseases and pests.
Processing of raspberries begins in early spring, after the snow cover has melted and along the swelling buds. The first preventive treatment can be done when the air warms up to +5 degrees during the day.
Spring processing ends a week before the flowering of the bushes. During the spring, 3-4 sprayings are carried out.
Processing is carried out in accordance with the climatic conditions of the region. The colder, the later work begins to protect raspberries from diseases and pests.
- Raspberry processing in the South begins in the first days of March.
- In the central regions, it is produced from the first days of April to the beginning of May.
- In the Urals and Siberia, processing shifts until mid-April and lasts until the beginning of summer.
These dates are subject to change according to weather conditions in the current year.
Raspberry processing is carried out in several stages. In early spring, preparations for fungal and viral diseases are used.
When the first young leaves appear, pest control begins. Re-treatment is carried out during the formation and swelling of the buds.
Before processing raspberries, preparatory measures are carried out.
If the raspberry tree was mulched for the winter, then the mulch, along with fallen leaves, must be removed so that the earth warms up faster. Then the removal of dry, damaged and diseased shoots is carried out. If necessary, thickened plantings are removed.
After that, you can start processing raspberry bushes from diseases and pests.
When planting a new raspberry, the plants are pre-treated. Seedlings are disinfected in a solution of potassium permanganate or copper sulfate for 20 minutes.
Chemistry
The first treatment of raspberries with chemistry is most often carried out with urea, copper sulfate and Bordeaux liquid.
These drugs accumulate in the soil and berries, so they must be used with caution and not exceeding the dosage.
Safer drugs include: Fufanon, Actellik, Fitolavin, Horus, Oksihom and Farmayod.
They are used according to the dosage on the package.
Many diseases are easier to prevent than to fight them, and the following means are used for this:
At this time, you can also use drugs such as: Bitoxibacillin, Fitoverm, Fitolavin and Farmayod.
In early May and early June (before flowering), raspberries are treated twice with biological products, for example, Agravertin or Phytoferm.
The drug Nitrafen helps to get rid of the beetle. After the snow cover melts and the bushes are tied up, the raspberries and the soil under it are abundantly sprayed with a solution (200 grams per bucket of water).
Many diseases are carried by pests and the fight against them allows you to avoid defeat.
- To protect raspberry bushes from gall midges, after loosening the soil to a depth of 7-10 centimeters, the land is cultivated with Fufanon(20 milliliters per bucket of water, consumption - 0.2 liters per bush). When budding, raspberries are sprayed with Fufanon (10 milliliters per bucket of water) or Aktellik (15 milliliters per bucket of water).
- Weevil, raspberry mite, gall midge are eliminated during the extension of flower brushes. Karbofos (10% solution) is used for processing.
- Stem fly and bud moth are eliminated during bud swelling. Pests are also eliminated with a 10% solution of Karbofos.
- The raspberry beetle is shaken off onto the film, and in case of severe damage it is eliminated by Karbofos, Aktelik, Fufanon, Phosbecid. Karbofos is diluted in a ratio of 75 grams per bucket of water. Aktelik is prepared at the rate of 15 milliliters per 10 liters of water.
- The grape leafworm appears during a stretched, cool spring. The first treatment of raspberry bushes is carried out when the buds open, the second - a few days before flowering. The following drugs are used: Decis, Kinmiks, Bi-58, Danadim, Talstar KE, Inta-vir, Fury VE, Aktelik.
Urea treatment is carried out before bud break. It is used to protect against pests and as a nitrogen supplement to form young shoots.
Per square meter of landings, 20 grams of the product is required. 0.5 kilograms of urea dissolves in 9 liters of warm water.
To enhance the effect, copper sulfate is added to the urea solution (50 grams per bucket of solution).
The solution (from a watering can with a nozzle) is sprayed with raspberry bushes and the ground under them.
Copper sulfate is effective against fungal diseases (anthracnose, scab, rust, gray rot, septosporosis, powdery mildew, moniliosis, brown leaf spot).
To prepare the solution, 100 grams of vitriol and a bucket of warm water are taken.
They cannot spill the soil under raspberry bushes! This depresses the plants and leads to the accumulation of copper in the fruits. Spraying is carried out only on the bush.
Copper sulfate in the form of 1% Bordeaux liquid, Homa, Kuproskat is safer for humans.
To prepare Bordeaux liquid, 300 grams of vitriol and 400 grams of slaked lime are taken per 9 liters of water. The components are diluted separately in warm water. Then they are filtered, mixed and introduced into the water. Both the bushes and the soil around the plants are sprayed.
When processing raspberries, instead of chemistry (with moderate damage), you can use folk remedies. They are safer and at the same time help against many diseases and pests.
There are many ways that gardeners use, the most famous are the use of mustard, boiling water, ammonia.
mustard
Processing of raspberries with mustard is carried out to scare away the weevil.
In a bucket of water, 20 grams of dry mustard is diluted. The solution is infused for 12 hours.
They spray bushes. Processing is carried out early in the morning or in the evening.
Mustard powder can be replaced with soda: 2 tablespoons with a slide are diluted in a bucket of water.
boiling water
Processing with boiling water is carried out on sleeping plants. Boiling water kills harmful bacteria and viruses, eliminates wintering pests in the soil and plants. In addition, it accelerates the process of raspberry awakening and accelerates its growth.
After boiling, water is poured into a watering can with a sprayer. You can immediately boil water in an iron watering can. The bush and the soil under it are carefully spilled at a distance of 0.8-1 meters. When watering, the water cools down to 65-70 degrees and does not burn the plants. One watering can is enough for 2-3 raspberry bushes.
Subsequent mulching of the soil under raspberry needles, chopped straw or steamed sawdust prevents excessive evaporation of moisture and retains heat, which promotes plant growth.
ammonia
Ammonia is used against diseases and pests of raspberries and as an additional top dressing. Treatment with ammonia is carried out twice in the spring: before bud break and during budding.
The first treatment is carried out at an average daily air temperature of +10 degrees. The earth should have warmed up by this time.
For the solution, 2 tablespoons of ammonia, 2 tablespoons of liquid tar soap and 10 liters of water are taken. The ammonia is combined with soap and injected into the water. With a well-mixed solution, raspberries are sprayed over the bush. Processing is carried out in the evening, in dry, calm weather.
For watering raspberry bushes, 2-3 tablespoons of ammonia are taken in a bucket of water. One adult bush consumes 5 liters of solution. The solution is poured directly under the root on fresh mulch.
Such watering with a solution of ammonia increases the yield of raspberries, and strengthens the immunity of plants.
Other
The increased acidity of the soil provokes the spread of fungal diseases on raspberries. To deoxidize the soil, wood ash, dolomite flour or slaked lime are added to it (100 grams per square meter of beds).
For preventive purposes, pine needles are used against gray rot. It is laid out in the aisles of the raspberry. To protect against diseases and pests, dandelion, yarrow, onion, calendula, and garlic are used. All funds are used in the form of infusions.
Wormwood infusion repels many pests. To do this, dry branches of the plant or 350 grams of crushed raw materials are taken, poured with boiling water, infused for 10 hours. Raspberry processing is carried out early in the morning, in the evening or on a cloudy day.
An infusion of tansy also helps well in repelling pests.
700 grams of dry raw materials are poured with 10 liters of boiling water. The remedy is infused for a day. Before spraying, the finished infusion is diluted in a bucket of water (1: 1).
During the appearance of buds and flowers, a film is spread under the bushes and weevils and beetles are shaken off on it. The collected insects are destroyed.
When an aphid appears, it is washed off with a solution laundry soap.
For the first buds against the raspberry beetle and weevil, a daily infusion of red elderberry shoots or coniferous concentrate (300 grams per bucket of water) is used.
Swellings on the shoots and stems of raspberries indicate that it is affected by stem gall midge. Damaged areas of plants are cut off and burned.
Raspberries are susceptible to fungal and bacterial diseases, such as: chlorosis, anthracnose, gray rot, curl, powdery mildew, mosaic, rust, different types spotting, verticillium wilt, root bacterial cancer and others.
Some diseases are introduced when new plants are planted or may occur due to poor care.
Plants are carefully inspected and disinfected before planting.
Raspberry care must meet all requirements and include pruning, watering, loosening the soil, mulching, fertilizing and mandatory processing.
Many of the diseases are carried by harmful insects. Of these, raspberries are most often damaged by: raspberry beetles, aphids, raspberry and spider mites, weevils, stem flies, gall midges, kidney moths, glass cases.
To protect against diseases, pests are first eliminated.
To the most dangerous diseases include chlorosis, curl and raspberry growth.
Chlorosis penetrates through the places of damage, fractures of the bark and cuts. The carriers of the virus are nematodes, leafhoppers, aphids and mites. First, the leaf plates between the veins turn yellow on the plants, then the entire leaf turns yellow and wrinkles completely. The shoots become thin, stretch upwards, the berries are deformed, shrink, dry quickly. Provokes the development of the disease waterlogged soil and hyperacidity land in the garden with raspberries.
Such plantings need to be uprooted.
You can fix the problem and protect healthy plants by liming the soil and normalizing irrigation.
To protect plants from this disease, bushes are treated from pests.
Before and after flowering, raspberries are sprayed with a 10% solution of karbofos.
Mosaic appears as spots, specks, streaks or a mesh on the leaves. Proper care and preventive spraying of bushes against aphids (disease vectors) helps to protect plants. The affected bushes are immediately removed from the site and sent to the fire.
The leaves may also turn yellow due to the goiter of the roots, root cancer. At the same time, tuberous growths form on the roots, the shoots do not grow, the berries lose their sweetness, they become insipid in taste. Most often, raspberries suffer from these diseases in an area with neutral or slightly alkaline soil. To prevent infection with goiter, root cancer, before planting plants in the ground, raspberry roots are checked for swelling. Damaged areas are cut out to healthy tissue. The root cut is treated with a 1% solution of copper sulphate.
Mycoplasma disease on raspberries it forms many infertile thin, low shoots 35-50 centimeters high, up to 200 pieces per plant. Affected bushes must be destroyed immediately. This disease is carried by cicadas. Fighting them allows you to protect the raspberry from the disease.
Curly raspberry manifested by shallowing, wrinkling and hardening of foliage. The bottom of the leaf turns brown. The berries become sour in taste, dry out. The infected plant dies within 3 years.
This disease cannot be cured. Affected bushes are dug up and removed from the beds.
Didimella or raspberry spot leads to the drying of the bushes. Light purple spots appear on non-lignified stems. They darken over time, become larger. The edges become red-brown, and the center of the spots is covered with black dots. The spots merge, become covered with cracks, the shoots break.
1 time spraying is carried out on young shoots, 2 times a few days before flowering, 3 times after flowering, 4 times after harvesting. Processing chemicals and folk remedies protection.
Raspberry rust shows up as dark spots. Leaves dry up and fall off when damaged. The stems are covered with dark brown cankers. Sick bushes are destroyed. Spring treatment of plants with a 1% solution of Bordeaux liquid protects the bushes from the fungus.
Anthracnose appears as gray spots on the foliage with a bright purple border. They blur, merge and form ulcers. The leaves gradually curl and die. The stems begin to peel off the bark. Berries lose their shape, darken. Bordeaux liquid, Topaz, Nitrafen helps to fight the disease.

To protect the raspberries from diseases and pests, it is necessary to carry out preventive treatments in a timely manner, and at the first signs of damage, immediately deal with the problems that have arisen.
Raspberries, like all other plants, require attention. By timely spraying bushes, you can not only protect them from ailments, but also increase productivity.
Raspberries are one of the most common berries in Russia. Delicious, sweet, extremely healthy. During the summer season, you want to eat plenty of fragrant berries, feed them to children and grandchildren, cook compotes and jams for the winter. To realize the entire list of desires, you will need a lot of raspberries, so the issues of increasing productivity and preserving the quality of fruits should be given increased attention. Pests and diseases of raspberries can negate all the gardener's efforts to grow raspberries. Before writing the article, we got acquainted with a large number of notes on the processing of raspberries in the spring. However, the lion's share of the material contained general information associated with spring pruning of bushes, their top dressing, soil mulching, etc. There were very few specific clear instructions specifically for spring treatment from diseases and pests. We will try to fill this gap, approach the problem in a structured way and describe all options for protecting raspberries with both chemical and folk remedies.
When to process.
The first preventive treatment against diseases and pests of raspberries must be carried out in early spring. On Russian territory early spring the concept is flexible. When plants bloom in the southern regions, snow may still lie in the Urals and Siberia, therefore, first of all, it is worth focusing not on specific dates, but on weather conditions and vegetation signs of the plant. The first spring spraying should be done from the moment of spring pruning of the shrub (this issue is discussed in detail in a separate one) and ended about a week before flowering begins. It is irrational to carry out pruning before, firstly, the process will be more laborious and costly, and secondly, why pour excess “poison” on the soil if you already remove some of the pests and diseased stems from the raspberries during pruning. Spraying later - during flowering, is generally strictly prohibited. The protective preparation will scare away pollinating insects. You will most likely get rid of diseases and pests, but you will not see a crop from unpollinated plants either. If you often visit your site and have the opportunity to carry out agrotechnical activities just in time, then optimum time spring spraying of raspberries is a period of active budding, and this is about 7-10 days before flowering, i.e. the very end of the interval we described.
Pest control
Processing raspberries in early spring from pests depends on whether you know exactly what kind of pests the raspberry is affected or whether you want to use some kind of universal remedy for everything and hope that it will help with your ailment. How to determine which pests are terrorizing your raspberries? In the "" section of the website, the site describes in detail all possible pests, indicating their impact on plants and preventive and control measures. But specifically, we will discuss the protection of raspberries from the most famous pests in early spring in the current article.
raspberry beetle
A large number of chemicals successfully fight the raspberry beetle. In addition, insecticides from the raspberry beetle destroy the larvae and adults of the weevil and leafworm, so with one spray you can defeat several misfortunes at once.
What and in what proportions should be used in the end? The preparations "Iskra", "Confidor", "Guapsin", "Inta-Vir", "Nitrofen" are suitable for us. The drug should be diluted in accordance with the instructions on the package, for example, half a Iskra tablet is diluted in 5 liters of water, and Karbofos will need 45 g for the same 5 liters.
Among folk remedies, a popular remedy for processing raspberries from the raspberry beetle in early spring is tansy infusion. To prepare an infusion, 300 g of tansy is poured into 5 liters of water and kept for about a day, after which it is brought to a boil and simmered for about ½ hour. Another 5 liters of water is added to the resulting solution, filtered and used for spraying.
stem fly
In case of damage to the raspberry by the stem fly, the preparations already described can be used: Iskra, Karbofos. Many gardeners give their preference to the preparation of the intestinal action "Aktellik". To prepare a working solution, 1 ampoule of the drug (2 ml) is diluted in 2 liters. water. It is advisable to spray Actellik in early spring, the product is toxic to bees and it is strictly forbidden to use it during flowering.
raspberry gall midge
The drug Actellik, already known to us, is also successfully used for spring spraying from raspberry gall midge. It is also worth paying attention to Fufanon. This drug is diluted in a proportion of 1 g / 1 liter. water, and each plant takes about 2 liters. facilities.
Spider mite.
One of the most popular forms spring processing raspberries from spider mites - spraying with colloidal sulfur. 100 g of the product is diluted in a 10-liter bucket and the plants are sprayed with the resulting solution before flowering.
Raspberry-strawberry weevil.
The raspberry-strawberry weevil affects the buds, so spraying from it is carried out during the period of active budding, i.e. not in the very early spring, after the snow has melted, but about a week before flowering. To combat the pest, you can do without chemicals, a folk remedy prepared on the basis of garlic has proven itself well. For cooking, you will need to stir 30 g of garlic grated on a fine grater in a glass of water and insist the "raspberry medicine" for 5 days in a dark place. Then strain the composition and dilute a quarter cup of the resulting solution in a glass of water and spray with the resulting mixture. Garlic spraying also helps to combat spider mites, as well as many fungal diseases of raspberries.
If you carried out the spring processing of raspberries from the raspberry beetle, then additional processing from the raspberry-strawberry weevil is no longer required.
For a long time, Bordeaux liquid was considered a universal remedy that helps in a complex way from many pests, and it is actively used to this day. However, time does not stand still, and now there are more effective and safe drugs. For example, Nitrafen, Topaz, Aktellik, have a wide spectrum of action and are quite safe for humans.
Disease protection
Treatment of raspberries in early spring from diseases most often consists in spraying the plant with Bordeaux liquid. The first spraying is carried out immediately after the snow melts, using a 3% solution of this fungicide. At this time, spring sanitary pruning has already been carried out, the diseased sections of the stems have been removed, therefore it is extremely difficult to say which of the diseases will develop in the future. Bordeaux mixture is considered a universal remedy not only for pest control, but also for the prevention of many diseases. If some disease begins to actively affect raspberry plantations, then it will be necessary to deal with it pointwise, possibly using some kind of specialized fungicide.
Gray rot
One treatment with Bordeaux liquid, carried out in early spring, should be enough to protect the raspberries from gray rot. If, in the past season, the disease actively manifested itself, and you want to play it safe, then you additionally need to spray with a 1% solution of Bordeaux mixture during the budding period. The method of our grandmothers, who in the spring laid out pine needles in raspberries, which mulches the soil and helps in the fight against gray rot, has also proven itself well.
Anthracnose
One of the best drugs for raspberry anthracnose is Nitrafen. Treatment with this tool is recommended in early spring, before the buds swell. 150 g. Nitrafen is diluted with 10 liters. water and spraying. Nitrafen has a wide range of applications, therefore it can be considered as one of the main means for spring treatment of raspberries from pests and diseases.
The most popular means of spring processing of raspberries
Ammonia
Processing raspberries with ammonia in the spring solves 2 problems at once. Firstly, ammonia is an excellent tool for the prevention of a wide range of diseases and pests, and secondly, a source of nitrogen, which is especially needed by raspberries in the spring for an active set of green mass. In order to understand the action of ammonia, you need to understand what it is in terms of composition. If you look at the instructions, we will see that ammonia is nothing more than a 10% ammonia solution. And all organic fertilizers, for example, bird droppings, pass as a result chemical reactions just into ammonia, which then in the soil under the influence of oxygen turns into nitrates and nitrites, which are already absorbed by the root system of plants. It turns out ammonia - this is exactly the same fertilizer as organic matter, you should not be afraid of it, it cannot bring anything "bad" into the soil.
For raspberries, ammonia is added at the rate of 5 liters of working solution per 1 bush. The working solution itself is made by mixing 1-2 tablespoons of ammonia with 5 liters of water. The solution is poured over the soil around the plant. Watering should be done in the spring, but not early, the soil should already warm up, otherwise the ammonia simply will not be absorbed by the roots. Excellent results are shown by the combination of adding ammonia to the soil with mulching.
Be careful when working with ammonia! Alcohol can cause skin burns, damage to the mucous membranes of the eyes, so it is better to carry out the treatment with gloves and take precautions.
Urea
Spring processing of raspberries with urea (urea) is similar to the treatment with ammonia. With one tool, we again kill two birds with one stone. We feed the plant with nitrogen that is so necessary in the spring and fight diseases and pests. It is for the purpose of pest control that the carbamide solution must be concentrated, because. destruction occurs by contact and a “weak” solution simply will not work. A concentrated solution can lead to burns of young shoots and foliage, so spraying can only be done in early spring, before the buds swell. To prepare a solution, 350 g of urea is diluted in a 5-liter bucket. One bucket of the mixture is enough for about 20 m2 of raspberries.
Boiling water
One of the proven means of our grandmothers is the processing of raspberries in spring with boiling water. This method seduces with the absence of chemistry, economy, while being very effective. Spraying raspberries with boiling water must be carried out before bud break in order to prevent the plant from burning and slowing subsequent growth. For the event, the earliest spring is suitable, until the snow has melted, or immediately after the descent. Water temperature for raspberries should be maintained in the range of 60-70 degrees. This temperature regime will allow you to destroy most pests and spores of fungal diseases, while not harming the plant. For 1 bush, you need to spend about 1 watering can of boiling water. Watering must be carried out at one time, so the kidneys do not have time to heat up and will not be damaged. The soil should not be spilled with boiling water, the raspberry roots are close to the surface, so they can get burned. When processing stems on the ground, it is better to lay polyethylene so that boiling water does not penetrate the soil. To enhance the effect, caustic soda is often added to boiling water at the rate of a tablespoon per watering can. Do not confuse ordinary baking soda with caustic soda, they have different sodium derivatives and different pH levels.
blue vitriol
Processing raspberries with copper sulfate in the spring is an effective tool for the prevention of fungal diseases, primarily anthracnose and gray rot. Copper sulfate is precisely a prophylactic drug, so it is used before the growing season, this is early spring immediately after the snow melts. If the treatment is carried out later, then copper sulfate will no longer help, it will not be able to cure the anthracnose that has already spread through the plants, in addition, the agent can accumulate in berries and their use is prohibited. To prepare a solution, 50 g of a copper solution is diluted in a 5-liter bucket of water. Both the stems and the soil around the plants are sprayed, a 5-liter bucket is enough for about 10-15 bushes.
inkstone
Processing raspberries in the spring with iron sulphate is also extremely effective. In some sources, there is information that only copper sulfate should be used for raspberries, somewhere in general copper and iron sulfate are considered the same remedy, so let's figure it out together whether to use it or not and what iron sulfate will give us in the spring. Iron vitriol is one of the main means that are used in horticulture to compensate for the lack of iron. As for raspberries, the lack of iron sulphate in this plant is common and is the cause of chlorosis. Processing with iron sulphate should be carried out immediately after the snow has melted, i.e. in the earliest spring, because otherwise there is a risk of damaging young kidneys. The working solution is made by stirring 50 g of ferrous sulfate in 10 liters. water.
Bordeaux mixture
Processing raspberries in early spring with Bordeaux liquid is a proven way to prevent most diseases over the years. Spraying is carried out in 2 ways. The first time the treatment is carried out in early spring, before bud break, spraying a 3% solution of Bordeaux liquid (300 g of copper sulfate + 300 g of lime per 10 liters of water). The second time, raspberries are processed by buds before flowering using a 1% solution of 100 g of copper sulfate + 100 g of lime per 10 liters. water). It is worth noting that Bordeaux liquid is an effective drug, but rather old, there are currently safer drugs. Instead of Bordeaux mixture, Oksikhom, Ordan, Ditan are often used. For example, the same Oksikhom is bred in 10 liters. water is only 30 g, and to prepare a 3% solution of Bordeaux mixture, it needs 300 g. The constant use of Bordeaux mixture unnecessarily saturates the soil with copper, and copper, being a heavy metal, accumulates in the body and leads to liver problems.
Therefore, in order to get a decent harvest of raspberries, preventive treatments are indispensable.
All raspberry processing procedures begin to be carried out in early spring before bud break. Before processing, the bushes are examined, sick and.
All agrotechnical methods for combating diseases and pests are carried out in three steps:
- Before bud break.
- Before the beginning abundant flowering in the last decade of May.
- Before fruit set.
What to process
Chemical, biological and folk remedies can be used in the processing of the berry. Each of the methods is used at certain times during the growing season of raspberries:
- chemical are activated only before the flowering of raspberries;
- biological are launched throughout the growing season;
- folk are used for any period of cultivation.
