Treatment of raspberries from fungal diseases. Proven methods for processing raspberries in the spring from diseases and pests. Processing raspberries against diseases in the spring: everything is not easy

Raspberries, like many other berry crops, need protection from diseases and pests. Experienced gardeners know how difficult it is to get rid of insects or cure bushes of infections. Therefore, they try to in early spring preventive treatment using various means and preparations.

Raspberry processing features

Spring processing of the berry begins early, as soon as the snow melts. In the regions of Russia, which are so different in their climatic conditions, they are guided by the weather and air temperature. At an indicator of + 5ºC ... + 6ºC, when swelling and bud break have not yet begun, the first sprayings begin.

It is advisable to carry out several treatments with various preparations, having time before the flowering of the bushes. Usually in the middle lane, such a period begins in early April, in the northern regions - mid-April.

Before processing, the raspberries are put in order:

• remove debris and last year's leaves under the bushes;
• cut diseased, dry, broken shoots;
• remove shoots that have not survived wintering;
• cut out the growth.

For work, only disinfected tools (secateurs, knives, garden shears) are used, be sure to disinfect them with special solutions after each treatment.

Almost every gardener plants garden plot useful and fragrant raspberries. There are times when raspberry bushes begin to bear fruit poorly due to insect attacks or diseases. In order for the planted plants to get sick less often, it is necessary to figure out in advance how to treat raspberries from pests during fruiting and flowering.

Before protecting shrubs from worms in berries and diseases, it is necessary to determine when it is best to treat. Experienced gardeners recommend processing a remontant bush in the spring, in the first half of April, when the first snow melts and the first buds begin to appear on the seedlings. In March, spraying is not done, since the daily temperature can drop below five degrees Celsius.

You can also process plants in the fall, after the foliage has fallen. In early November, branches that have ceased to bear fruit are cut from shrubs and the most weakened shoots are removed. Only after preliminary pruning, preventive treatment is carried out.

Best Treatments and Treatments

To choose the most effective tool for working with raspberries, you need to figure out how it is better to spray it.

store products

Quite often, store chemicals are used to protect raspberry seedlings from ailments and insects. To effective drugs that are able to treat raspberry bushes include:

• Mikosan. It is used to increase the immunity of seedlings. The composition of the product contains components that help to quickly get rid of pathogens of fungal diseases.
• "Healthy garden". The drug is used to protect the berries from aphids, sawflies and other dangerous pests. The tool is made on the basis of sodium and is sold in the form of soluble granules.

Folk remedies

There are gardeners who prefer to save berries not with store-bought products, but with folk remedies.

copper sulphate

Spring and summer are the right time to treat raspberries with a solution made from copper sulfate. Before spraying, you need to figure out how to make a vitriol solution yourself. For therapeutic and prophylactic purposes, a slightly concentrated mixture is used. To prepare it, 150 grams of the substance is added to 8-9 liters of warm water. Then everything is stirred for 5-10 minutes and infused for half an hour.

It is necessary to spray seedlings with vitriol in protective gloves and goggles so that droplets of the product do not fall on the body. You also need to make sure that there are no small children and animals nearby.

iron vitriol

During flowering and when fruiting begins, you can use iron sulphate. It is used for such purposes:

• soil saturation with iron;
• treatment of wounds that may be on the surface of the branches;
• strengthening old raspberry bushes;
• prevention of the development of fungal pathologies;
• insect protection.

When creating a working solution, half a kilogram of the substance is added to a ten-liter container with water. The prepared product is used no more than twice a season. Raspberries are processed in the evening or morning, when there is no sun.

boiling water

Another common prevention method is the use of hot water. Boiling water is used in the following cases:

Before spraying a raspberry bush, it is necessary to protect its root system from boiling water. To do this, the surface of the soil is covered with polyethylene, which will not hot water get into the soil.

Urea

Some gardeners prefer to protect shrubs with urea. When working with urea, the following recommendations are followed:

• Preliminary preparation. Before processing, near each bush, the soil is loosened and weeds are cleaned.
• Select a day to work. A garden raspberry bush is treated with urea on sunny and calm days.
• Compliance with safety rules. It is necessary to work with the solution in rubber gloves, goggles and a mask.
• Mixture preparation. 750 grams of urea and 50 grams of copper sulfate are added to a bucket of water.

Raspberry shoots are watered with urea 3-4 times per season.

Bordeaux liquid

Most often, this tool is used when biological products are not able to protect the bush. Autumn is considered best time for the application of Bordeaux liquid. During this period, the bushes completely complete the growing season, and therefore the product will not be able to harm the plants.

To prepare the remedy with your own hands, half a kilogram of lime is added to three liters of water. After that, two more liters of warm water are poured into the container. Then 40 grams of copper sulfate are added to 10 liters of boiling water, after which the mixtures from two containers are mixed and infused for 20-30 hours.

Mustard and soda

To cure raspberry diseases, you can use a mixture made from soda and mustard. This is a universal mixture that can destroy chlorosis, as well as protect seedlings from rotting and anthracnose. Some use it to increase the amount of sugar in the berries and improve their taste.

When creating an effective remedy against raspberry diseases, 80 grams of soda and 20 grams of mustard powder are added to 5-6 liters of heated water. You can use the liquid after flowering is completed.

ammonia

Some people think that ammonia is only used in medicine, but this is not so. It is used in horticulture as a fertilizer and helps fight common diseases. Also, with the help of ammonia solutions, seedlings can be protected from such insects:

• ants;
• flower midges;
• bear;

A large amount of alcohol can harm the plant and therefore dosages must be observed when creating a solution. In a bucket with cold water 50-60 milliliters of alcohol are added with grated laundry soap. To prevent pests from appearing on the bushes, spraying is done 1-2 times a month.

Tar

To repel insects, tar is often used, which has a pungent odor. Shrubs are processed twice - before and after flowering. When creating a product, 2-3 spoons of tar are added to 10-15 liters of water.

Raspberry diseases and ways to deal with them: terms and technology for processing bushes

If you take care of the shrubs poorly, they begin to hurt and die. It is recommended to familiarize yourself with the characteristic features of common raspberry diseases and methods of their treatment.

How to treat raspberries from late blight (root rot)

The main cause of root rot in shrubs is high level soil moisture. The main symptoms of late blight include black plaque on the pistils, mold and yellowing of the foliage. Also, in diseased bushes, flowers are deformed and dry.

To combat the disease, use a garlic solution with manganese. It is prepared from 8-10 liters of warm water, two grated heads of garlic and 5 grams of manganese. For each diseased bush, half a liter of liquid is consumed.

The disease appears due to the ingress of bacteria into the root system of the raspberry seedling. The disease is accompanied by growths on the root collars and the lower part of the stem. The leaf plate is covered with yellow spots, which darken over time. Root cancer develops very quickly and therefore, when it appears listed symptoms need to start treatment.

To combat the disease, they use a one percent solution of copper sulfate, which destroys the pathogens of root cancer.

Root rot (phytophthora)

Phytophthora - dangerous disease, the causative agent of which is a fungus that develops under conditions high humidity. Each leaf of a diseased seedling begins to turn red and dry around the edges. If you do not treat phytophthora, the shoots dry out completely. There are several remedies for root rot:

• Chalk. 10 grams of chalk is mixed with 400 milliliters of water and 5 grams of copper sulfate. The solution is treated with the affected stems and leaves.
• Iodine. The substance is diluted with water in a ratio of one to five. Shrubs are sprayed with an iodine mixture 2-3 times a week.

Gray rot on raspberries leads to poor fruiting and death of berries. The fruit of infected bushes is covered with a bloom that has a brown color. Most often, gray rot appears on shrubs that are grown in waterlogged greenhouses. Also, the disease develops if the plant is grown near infected seedlings.

To save plants, experienced gardeners recommend getting rid of all infected berries and cutting stems that begin to wither.

verticillium wilt

July is the month when raspberry bushes start to get sick with verticillium wilt. The danger of the disease lies in the fact that it leads to a slowdown in fruiting and stops the development of the bush. First, a yellow coating appears on the leaves and stems, after which the shoots begin to wither.

It is impossible to cure the disease and therefore everything must be done so that the raspberries do not get sick with verticillium wilt. To do this, the bushes are regularly sprayed with fungicides and urea.

Chlorosis

The development of chlorosis on raspberry bushes is evidenced by yellow spotting on the leaf plate. This viral disease is very dangerous, as it is not easy to get rid of it. Chlorosis leads to a slowdown in the ripening of the crop and drying of the berries.

To protect the berries from the disease, the bushes are treated with a sulfate solution. Raspberries are processed in mid-March, when the first buds appear on the seedlings. You can also use a methyl emulsion, which is sprayed with raspberries two weeks before flowering.

Rust

Rust begins to develop in the last decade of May, when flowering ends. It is quite simple to identify the disease in time, since it has pronounced signs. The leaves of bushes infected with rust are covered with an orange bloom, which will become convex over time. A darker coating appears on the reverse side of the leaf plate.

Rust treatments include:

• Sagebrush. Fresh grass is poured with cold water and infused for 3-4 days. Then the liquid is filtered and used to process raspberries.
• Soda. Five spoons of the substance are mixed in 7-8 liters of water, after which the raspberry leaves are sprayed.

If there are yellow spots on raspberry leaves, it is highly likely that she has become ill with infectious chlorosis. First, yellowing appears near the veins, but gradually the surface of the leaves covers one large yellow spot.

To eliminate chlorosis, peat, compost and humus are added to the soil. Raspberries are also fed with potassium compounds that will help get rid of the symptoms of the disease.

Mosaic

Mosaic appears on the bushes after the attack of aphids, which is considered the main carrier of viral pathogens. Feature diseases - green and yellow spots on the leaves. If the mosaic is not treated for a long time, convex growths will appear on the surface of the leaf plates. Infected shrubs should be watered with Kemifos and Fufanon.

Curly

With the development of curliness, the trunk of the shrubs darkens, and the raspberry shoots shorten and bend at the edge. If the disease appeared in the fall, all the leaves acquire a bronze hue and begin to die off. If you do not treat curliness, the bushes will stop growing. In the treatment of the disease, fungicides and copper sulfate are used.

Anthracnose

Anthracnose is a dangerous disease in which a red coating with a brownish tint appears on the surface of the foliage. The disease appears due to a lack of organic top dressing and the use of infected tools.

To quickly get rid of fungal pathology, diseased stems of shrubs are cut off and potash and phosphorus top dressings are added to the soil.

Septoria (white spot)

Due to septoria, specks appear on the surface of raspberry leaves, which are colored in White color with brown border. Gradually, the spotting passes from the leaves to the main stem and shoots.

Infected bushes need proper care, without which they will die. Diseased leaves are carefully removed from the shrubs, after which the raspberries are sprayed with fungicides.

Didimellez (didimella)

Didimella is a common disease that affects not only raspberries, but also other berries. On the initial stage the development of the disease leaves with stems are covered with purple spots. Over time, the spotting darkens, hardens and cracks. When didimella appears on raspberry bushes, the following control measures are used:

• biological products;
• Bordeaux liquid;
• iron or copper sulfate.

How to treat raspberries from pests

To protect raspberry bushes from insects, you need to decide how to spray them during cultivation.

The main reason for the appearance of wormy raspberries is the raspberry beetle, which attacks the bushes. The insect is activated in the second half of spring, when early berries begin to form. The pest feeds on leaves and fruits.

Since the bug infects the fruit, it should not be sprayed with chemicals. The only thing you can do with it is to collect manually.

stem gall midge

Rot on young berries may appear due to the attack of stem gall midges. Adult individuals lay eggs on leaves, from which caterpillars then appear. The young gall midge bites into the stems of raspberries and eats them out from the inside.

Stems that have been invaded by pests will have to be completely cut out and burned.

stem fly

The most dangerous pest for raspberry bushes are stem fly larvae. They, like gall midges, penetrate the shoots and feed on plant sap. Because of this, the leaves and stems of raspberries turn red, and a gray coating appears on the berries.

So that the fly larvae do not spread throughout the plant, the affected shoots are cut out, after which wood ash with vitriol is added to the soil.

raspberry mite

It is difficult to notice this insect in time, since its length rarely reaches one millimeter. You can detect raspberry mites only when they have covered the entire bush. Manual collection of insects will not help get rid of ticks and therefore you will have to use preparations for spraying raspberry seedlings. To effective means include "Nystatin" and "Trichopol".

If there is a web on the raspberry stalks, then the raspberry bush was attacked spider mite. Also, the appearance of a tick is evidenced by an oily coating located on the back of the leaves. Most often, the tick bug appears in May, so the preventive treatment of berries is carried out in April. They are sprayed with urea, vitriol and fungicides.

Raspberry-strawberry weevil or flower beetle

This is a small caterpillar that feeds on young foliage and lays eggs on it. The insect is activated during the flowering period and penetrates the flower buds to eat them from the inside. Main preventive measure the appearance of weevils - regular inspection of the leaves and removal of delayed larvae.

kidney moth

If a brown butterfly flies near the bushes, it means that a kidney moth attacked the plant. Adults do not harm raspberry seedlings, since the main damage is caused by their larvae. They penetrate the young stems and buds of seedlings to suck the juice out of them. This leads to slowdown further development shoots.

leaf roller

Leafworms lay their larvae on the inside of raspberry leaves. Young individuals feed on the juice of the leaves and penetrate the fruits, due to which the crop becomes rotten and wormy. The leaf roller attacks plants from the end of May to the first half of September.

Effective pest control is used folk method- wormwood decoction with the addition of tomato tops and tobacco.

Raspberry moth gets into the shoots of shrubs, because of which their growth stops and growth develops. Also, moth larvae can penetrate ripe berries and ruin them. All drying stems that are affected by insects are cut out and burned.

leafhopper

This is a small pest that attacks raspberries and vegetables. You can find leafhoppers on raspberry bushes by light spotting on the surface of the sheets. Many people think that such insects cannot harm raspberries, but this is not so. If you do not get rid of them in time, the bush will dry out. Fungicides, as well as an infusion of garlic and wormwood, will help get rid of leafhoppers.

Raspberry glass

This is a yellowish butterfly that lays larvae on the foliage of raspberry seedlings, which suck the juice from the bushes. Most often, the glasswort lays its eggs at the bottom of the stems so that the larvae can penetrate to the roots. Shoots infected with a glass case cease to bear fruit and develop. A white powdery coating appears on them, which rots over time.

Conclusion

People who grow raspberry bushes often encounter pests and diseases that reduce yields. To protect plants, it is recommended that you familiarize yourself with the main means that are used to process raspberries.

Raspberry is a widespread shrub. At proper care gives a rich harvest. However, the shrub is susceptible to various diseases and insect pests. To reduce the risk of their occurrence, it is necessary to carry out preventive treatment. If, nevertheless, pests or diseases are taken by surprise, urgent treatment is required.

Preventive treatment of raspberry bushes from diseases and pests reduces the risk of damage to the shrub during the period of growth, flowering and ripening of berries.

spring processing

Processing of raspberries from diseases and pests begins in early spring, after the snow melts and the earth warms up. First, the area with shrubs is put in order. Frostbite, broken and rotten stems are cut off. Shoots growing inside the bush are also removed.

Cut stems in early spring. In the middle or end of the season, pruning is not recommended, as the volume of fruiting is significantly reduced.

Last year's grass and foliage are raked from the ground. All stems and foliage are burned. This is due to the fact that in the foliage can
be pest larvae. The situation is similar with stems. Rotten and affected shoots may contain insect larvae.

The soil is dug up, nitrogen fertilizers are applied to it. After that, each bush is tied to a trellis. As a fertilizer, urea is used, which is rich in nitrogen. Saturating the plant, it strengthens it, makes it resistant to diseases. Urea is taken at the rate of 15-20 g per 1 sq. m.

For the prevention of diseases, various formulations are used. The solution is sprayed on the stems of the shrub and the soil around it. A solution of Bordeaux liquid or nitrafen helps to cope with many diseases. The first treatment is carried out before bud break. Depending on the condition of the plant in the last season, it may be necessary to re-spray the solution in spring and summer.

It is impossible to carry out treatment with agents from diseases and harmful insects during the flowering period. This repels insects that pollinate the flowers.

Also, before bud break, it is required to process raspberries from harmful insects. For this, various compositions are also used. Each tool is designed to prevent the appearance of a particular pest. Atellik and karbofos have a good effect.

autumn processing

After the end of fruiting, raspberries are re-treated with compounds from diseases and pests.

Before the onset of cold weather, all stems of the 2nd year, diseased and weak branches are cut off. Next year, there will be no more fruits on them, and weak branches will only interfere with growth.

The stems of the first year are cut to a height that can be reached with a pruner from the ground. Next, the foliage is removed from them. To do this, a glove is put on the hand, the shoot is slightly clamped in the hand, which is carried out from the bottom up. The remaining leaves are cut with secateurs.

Movement should be directed precisely from the bottom up. Otherwise, the kidneys will be damaged or completely removed.

When growing raspberries, it should be noted that many diseases occur due to excessive moisture and high acidity of the soil. Therefore, it is necessary to strictly regulate the watering of the plant. To reduce acidity, wood ash, slaked lime or dolomite flour are added to the soil. For 1 sq. m is taken about 150 g of the substance.

Pest control

Raspberry processing carried out in the spring minimizes the risk of plant damage by various pests. There are many insects that damage the health of the plant.

Aphid

This insect infects many fruit bushes and trees. The pest feeds on the sap of the plant, which leads to twisting of the leaves, drying of the stems.

To combat insects, use an actellik solution (15 ml per 10 liters of pure water), or a 10% solution of karbofos.

raspberry beetle

To prevent the appearance of a pest, raspberries are treated with a solution of nitrafen. To prepare the mixture for
10 liters of pure water is taken 200 g of the substance. The solution is sprayed with branches and soil around the bushes. Processing is carried out after pruning and tying the stems. A 10% solution of karbofos also helps to get rid of the insect.

In the fight against the beetle, you can also use folk remedies. For this, an infusion of bitter wormwood and marigold flowers is used. It is prepared in the following way. 100 g of crushed marigolds are poured into 5 liters of water and kept for 2 days. Bitter wormwood is poured with water in the same ratio, but the infusion is kept for 2-3 hours. Then both solutions are filtered and mixed with each other (in equal proportions). Raspberries and soil are treated with the resulting composition.

stem fly

Insects damage the stems. The fly infects young shoots, which leads to their decay and infection.

To prevent pest damage in early spring, mulching is carried out. Well, pine needles help with this. Sprinkling makes it difficult for the larvae to leave the ground.

Weevil

To get rid of the weevil, they are treated with a 10% solution of karbofos, or actellik (15 ml per 10 l of water).

Of the folk remedies for insect control, mustard is used. For spraying, a solution is prepared from 10 liters of water mixed with 20 g of the product. The solution is kept for 12 hours, after which the bushes are processed. Can be used instead of mustard baking soda: 2 tbsp. spoons in a bucket of water.

stem gall midge

Raspberries are harmed by a larva, not an adult. A sign of defeat are growths on the branches.

If affected stems are identified, they are cut and burned. To prevent the appearance of larvae in the spring, processing is also carried out. Fufanon has a good effect. The substance in a volume of 15-20 ml is dissolved in 10 liters of pure water. The resulting solution cultivates the earth. Previously, the soil is dug up to a depth of 10-15 cm. The solution is also re-treated during the period of bud setting. But already 10 ml of Fufanon are dissolved in 10 liters of water. Careful spraying should be carried out: 150-200 ml of solution should go to one bush.

Actellik solution has a similar effect. To prepare it, 15 ml of the substance is diluted in 10 liters of water. All bushes are sprayed with the composition.

kidney moth

The kidney moth is a red butterfly that infects the buds of plants. And insect larvae damage the stems. In an old raspberry mole can destroy up to 90% of the kidneys.

To prevent pest damage in the spring, you need to cut off the dried shoots, and in the fall, rake all the fallen leaves. Spraying is also carried out before flowering with a 2% solution of karbofos, or with insecticides such as Corfidor, Iskra and Decis.

spider mite

Signs of damage by a spider mite are the presence of cobwebs on the underside of the leaves, which eventually become discolored, begin to dry and completely fall off. Most often, the pest infects raspberries during prolonged dry and hot weather. The most effective way to deal with a tick is spraying with acaricides (a solution of karbofos, colloidal sulfur, phosphamide, etc.). With numerous individuals, the treatment must be carried out up to 4 times, with an interval between each spraying of 10 days.

Raspberry diseases

Various diseases can reduce the fruiting of raspberries. Moreover, they can lead to the complete death of the bush. To prevent this from happening, the plant is treated in the spring.

Anthracnose

This disease is caused by fungi. A sign of the disease is the formation of pinkish or purple blotches on the leaves of the plant. Over time, the size of the spots increases, and they acquire a gray tint.

For prevention, raspberries are treated with Nitrafen. To prepare the solution, take 200 ml of the substance and dilute it in 10 liters of water. The resulting composition is sprayed with raspberries.

A solution of copper sulphate helps a lot. To obtain a solution, 50 g of the substance is taken per 5 liters of pure water. The composition is sprayed with raspberry stalks and the soil around it.

It is forbidden to treat with copper sulfate during the growing season and plant growth, as the substance accumulates in shoots and berries.

white spotting

The disease affects stems and leaves. It manifests itself in the form of brown spots on blossoming foliage or on young shoots. Over time, the entire sheet becomes light, holes appear. Cracks and peeling of the bark appear on the stems with white spotting.

To prevent the disease, spraying with a 1% solution of Bordeaux liquid is carried out. For treatment, colloidal sulfur is used. To obtain a solution, 40 g of the substance should be dissolved in 10 liters of water.

Gray rot

This is a fungal infection that is characterized by the appearance of gray spots on the berries themselves. Over time, the entire fruit is covered with a brown coating. The infection also affects the leaves: spots are formed on them in a similar brown-gray color. For the prevention of the disease, Nitrafen is also used, or a 3% solution of Bordeaux mixture.

Rust

Another fungal disease that manifests itself in the form of bright orange growths on the underside of the leaves. The disease develops very quickly, which leads to the drying out of all raspberries.

To prevent infection in the spring, they are treated with a 3% solution of Bordeaux mixture.

powdery mildew

Powdery mildew is a fungal disease. It affects almost all raspberries: leaves, berries and shoot growth points. A whitish coating forms on diseased areas. The development of powdery mildew can provoke high humidity and temperature.

To prevent the development of the disease in the spring, raspberries are treated with a solution of lime and copper sulfate. For its preparation, 400 g of lime and 300 g of copper sulfate are taken and mixed in 10 liters of water. Repeat spraying should be before flowering and after harvesting. At the same time, 100 g of lime and copper sulfate are dissolved in 10 liters of water. Also in the spring, you can carry out preventive treatment with Bordeaux mixture.

root cancer

The disease is very difficult to detect at an early stage of development. Signs of root cancer are a change in the taste of fruits and an almost imperceptible deterioration in shoot growth. When identifying these signs, it is necessary to examine the roots. If bulges appeared on them, then it means that the raspberries were struck by root cancer. Bulges can reach sizes up to 5 cm.

To prevent the development of the disease, raspberries need to be transplanted every 2-3 years. If, nevertheless, the cancer struck a shrub, then before planting, the roots should be soaked in a solution of copper sulfate. Processing is carried out for 10-20 minutes. To prepare a solution, 100 g of copper sulfate are dissolved in 10 liters of water.

Raspberry chlorosis

Raspberry chlorosis or jaundice is a viral disease. Initially, the leaf areas between the veins are affected, and then the entire plate turns yellow and twists. The stems become thin, weak and elongated. The fruits shrink, deform and quickly dry out.

There is no cure for this disease. Only the creation of favorable conditions for growth can prevent its development. To do this, you need to lower the acidity of the soil and regulate watering to ensure normal humidity. In case of damage by chlorosis, raspberries must be dug up and burned. You can plant a shrub in this place no earlier than 10 years later.

Mycoplasma disease

Another disease that cannot be cured. It manifests itself in the form of the formation of many infertile small stems 30-50 cm high. Up to 200 branches can form on one bush. If such a plant is identified, it must be immediately destroyed. The reason for the development of mycoplasma disease is the spread of the virus by insects or the planting of diseased raspberries.

Mosaic

Viral disease that affects the stems and leaves. Signs of a mosaic are the appearance of yellow spots with brown swellings. The diseased shrub becomes weak, new shoots practically do not grow, and the berries become small and sour.

To prevent the disease, it is necessary to cut diseased stems, remove weeds around raspberries and feed the soil with organic fertilizers.

Curly

Variety viral disease, which manifests itself in the form of twisting leaves and a decrease in the height of the shoots. Fruits that cannot fully set also suffer.

Curl prevention is similar to the methods used to prevent mosaic development.

Thus, the treatment of raspberries from diseases and pests can solve a number of problems. To make the shrub happy good harvest, it is important to properly care for the plant and carry out prevention. If everything is done properly, then in the process of growth, flowering and fruiting, problems do not arise.

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

Treatment

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

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

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

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

What should be done:

• Trim dried tops.
• Broken or flabby branches.
• Those trunks that can begin to grow inside the bush.
• Dried leaves.

spraying

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

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

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

It is necessary to treat raspberries with this composition before flowering and bud break because it is better not to disturb young flowers, which, due to stress, may not produce a crop.

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

If, for example, your bush suffers from powdery mildew, it is better to use the Topaz store remedy. If raspberry treatment is required before flowering from pests, and you are against the use of chemicals, you can use folk remedies, for example, a decoction of needles is able to destroy gray rot.

During flowering

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

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

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

By carrying out activities to combat micro pests in spring and summer, you can increase the overall yield. In addition, he will be larger and healthier, since nothing will prevent him from growing and pouring.

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

Beetle treatment

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

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

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

Conclusion

If an illness is detected in a raspberry plant, appropriate measures must be taken immediately, otherwise you risk losing your entire crop.

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

Everyone who cares about the health of the berry grower and wants to get a generous return: how to process raspberries in the spring, when and when exactly: methods, our mistakes. When spraying is money and raspberries down the drain, why proven means do not work, and what to do.

Processing raspberries in the spring: what are we doing wrong

Why is it important to process raspberries in early spring and repeat over time.

1. The timing of the awakening of pests: they are early, and vary.
2. During active budding, opening of buds, there is a high risk of damage to them.
3. When flowering, raspberries cannot be processed: this will scare away pollinators.

To each his own. Each pest reacts to a specific substance. There are no universal ones! So, the leaf-roller in the phase of wrapped leaves is invulnerable to Calypso, Aktara, Mospilan, where a.v. - Chloronictinoids. Phosphoorganic substances are needed, on the basis of which Zolon, Bazudin, Bi 58, Decis Forte.

Systemic insecticides (hornikitinils, oxadiazines, cyanamides, etc.) that are active against gnawers will not be active against mites.

What to do? There are acaracids - Karbafos, Zolon, Metaphos, Cydial, colloidal sulfur.

Important! Insecticides and acaracides are not the same thing. The first destroy all insects, the second - only ticks. The insecticide can sometimes be an acaricide.

Everything has its time. Raspberry processing is carried out not only in early spring.

• The raspberry mosquito flies out with the beginning of the growing season, and after pupation and emergence during flowering, when the female lays eggs, all treatments are useless: the larva makes its way into the tissue of the stems in order to get out again in a couple of months.
• The stem gall midge lays eggs later, at higher t.
• The weevil strikes the buds - and early spring processing is not a hindrance to it.
• The spider mite is active throughout the growing season.

Air temperature. All drugs at low t are less effective. Optimum temperature Usage is usually indicated in the instructions. At t below +12…+15 °C, above +20…+25 °C, the efficiency of many is minimal.

So, Calypso works at t above t +10 °C, Karate is more effective at t below +20 °C.

Adhesives needed. Without them, the drug rolls down the sheet, and the effectiveness is reduced to nothing. Do not use soapy water or other household methods. Why? Soap is alkaline and reduces effectiveness.

What to do? If you are not ready to buy, the method of the times of the USSR: sugar syrup - 1.st. spoon for 1 liter of water.

How to process raspberries in the spring against pests: to each his own

The treatment of raspberries in the spring from pests begins at the time when the bud bursts, along a green cone, against some - in the beginning-middle of budding, 7-10 days before flowering - this general rule. And in 80% of cases, spraying has to be repeated.

How to spray raspberries in the spring against pests: types, preparations + table by development phases

How to spray raspberries in early spring? For complex eradicating spraying, treatment is carried out with urea (300-350 g per 10 l, consumption per 20 m2), 1-2% solution of copper sulphate over a green cone. It can be either urea, blue vitriol, or ordinary Karbofos.

Stem gall midge (fly)

The first treatment is carried out in the spring, after the snow has left with vitriol, urea. Before flowering in May, Actellik, Iskra, Karbofos, Agrovertin are used.

Advice! Be sure to mulch plantings: this makes it difficult for insects to fly out.

Raspberry gall midge (raspberry mosquito)

The effect is facilitated by loosening and spraying the near-stem circle, a high-quality strait of the stems at the base.

The first spraying of raspberries in early spring from pests - Actellik, Karbafos, Karate, Calypso, Nurell, etc. Repeated - before the buds open - Actellik, Funfaron.

raspberry beetle

From damaging leaves, buds, flowers and berries, it is important to carry out several activities. After pruning - Decis, Confidor, Spark, Guapsin, Spark. And they say that the infusion of tansy is effective. And most importantly - digging the soil in order to extract wintering larvae to the surface.

spider mite

It is recognized by the white holes in the leaves. Sweet Tooth deals huge damage: the entire bush withers and dies. Most insecticides are powerless against it, and Cidial, Metaphos, colloidal sulfur will be used before the start of the growing season.

Weevil

It affects the buds where the female lays, which reduces the yield by up to 50%: it is important to carry out the treatment at the beginning of budding.

Bordeaux liquid and copper are generally ineffective: they use Topaz, Actellik, Kemifos, Fufron, Alatar in accordance with the instructions.

Table number 2. Spraying raspberries against diseases in the spring in different phases of development: preparations, application features.

Development phase	Pests and diseases	A drug	Application
Before bud break, at the beginning (bud cracking)	Shoot gall midge, leaf-eating	Karate Calypso Iskra Actellik Kemifos Karbofos	Spraying shoots, their bases, near-trunk circle
	Weevil	Aktellik Topaz Kemifos Fufron Altar	At the beginning of budding, before laying
Before flowering, in the phase of well developed leaves	Spider mite, rust	Thiovit Jet Cydial Metaphos	Processing of leaves on both sides, shoots, close circle
	raspberry beetle	Decis Confidor Iskra Guapsin Aktara
Before bud break	Shoot gall midge, stem fly	When landing in open ground by mixing with soil
In the phase of the beginning of blooming leaves	kidney moth	Kinmix
During bud break	spider mite	Zolon Metaphos Phosphamide Cydial colloidal sulfur	Be careful when testing on the leaves
In full bloom phase	Shoot gall midge, leafhoppers, raspberry beetle, leaf-eating, mites	Aktellik, Kemifos	Activities are carried out until the full bloom of the kidneys
	leaf roller	Bazudin Fufanon Aktelik Zolon

Important! Frequent use copper-containing preparations leads to their accumulation in the soil, fruits.

On the other hand, choosing the lesser of two evils, it is more rational to use contact preparations, to which copper and its derivatives belong, rather than systemic ones, albeit more effective ones.

Processing raspberries against diseases in the spring: everything is not easy

And disease is not easy. Of the fungal diseases, anthracnose, gray rot, leaf spots: it is much easier with them. But it is important to consider three points. Or even five.

1. All diseases are the result of low agricultural technology: dense plantings, dampness, lack of nutrition. Or infected planting material.
2. Processing is carried out before active sporulation of fungi, carriers of viral diseases.
3. Most drugs work by suppressing spores - not by the fungus itself - and have a certain period of action called the waiting period. The same applies to urea, copper preparations: the eradicating effect is due to the destruction of the living environment of fungi, and their fungicidal activity against raspberry diseases is not high, as practice has shown.
4. The waiting period is not what we think: this is not the time when you can eat raspberries. This is the expiration date of the substance. After its completion, the treatment is repeated - most fungal ones have several sporulation cycles in a season.
5. Biological products - a preventive measure, maximum suppression of sporulation. The effect is often based on the action of antagonist fungi - for example, Fitoverm (a.v. aversectin, based on strepiomycetic fungi). Their effect is difficult to underestimate at the initial stage, but even with a large-scale defeat, it should not be overestimated.

Handling Against Viral: Retreat to Win

Viral - this is a mosaic, leaf curl, sprouting, interveinal chlorosis. The reason is a weakened immune system, which means a lack of nutrition. And most importantly - carriers: aphids, leafhoppers and others.

The main method is the destruction of carriers and the bushes themselves, alas: agrochemistry is powerless against viral ailments.

Only a few means in combination with growth stimulants, top dressing will prolong the life of plants: there is no salvation against Fusarium wilt, overgrowth.

Humane in relation to health and an economical method will be the renewal of plantings.

Raspberry processing includes several stages. The first - in early spring along a green cone, then after 10-14 days, a third is possible before flowering.

About raspberry virus ailments:

Of the methods: Bordeaux liquid - immediately after the snow melts 2-3% r.-r, urea. The second as needed until the opening of the buds.

Raspberries are processed with copper 1% copper sulphate in the spring immediately after the snow leaves, after sanitary cleaning, trimming the tops. Consumption 10 liters per 15-20 m2).

How to process raspberries in spring? With the preparations listed below at the indicated time, by spraying, wetting all sides of the leaves, stems, slightly sprinkling the root circle.

When to process raspberries? In the southern regions, Ukraine, the southern regions of Belarus - the middle of April and even the beginning. In Central Russia - the end of April, with late spring in some years until the beginning of May.

Raspberries are treated against gray rot, Alternaria, purple spotting with 1% Bordeaux liquid at the beginning of budding, with a slight defeat of Kuproksat, with intense Oxych, Acrobat.

Table number 2. Spraying raspberries at leafing out and in the leafy phase.

Development phase	Pests and diseases	A drug	Application
In green cone phase	Anthracnose, didimella	Bordeaux mixture, copper preparations, urea	1-2% r.-r.
Before flowering, in the phase of the beginning of blooming leaves	Anthracnose, gray mold, purple leaf spot	Kemifos, Topaz, Thanos, Fundazol	Upon reaching the shoots of the current goal of 15-20 cm, paying special attention to the base of the shoots, leaves on both sides, wetting the near-trunk circle
Full foliage	Spider mite, rust	Thiovit Jet, Fitoverm	Processing of leaves on both sides, shoots, near-stem circle
	Purple spotting, anthracnose

In conclusion. The effect of many drugs has not been studied, as well as the possibility of their accumulation in the soil, fruits, and our body. How the processing of raspberries will turn out - only time will tell.

And if about the struggle until complete victory, then it is better to uproot the damaged bushes and send them outside the site: not a single drug will give a 100% guarantee. May your raspberries do not get sick, may no processing be needed, and the harvest will be good!
