How can you treat raspberries against pests during flowering and fruiting?

Almost every gardener plants a garden plot with healthy and aromatic raspberries. There are times when raspberry bushes begin to bear fruit poorly due to attack by insects or diseases. In order for planted plants to get sick less often, you need to figure out in advance how to treat raspberries against pests during fruiting and flowering.

When to treat raspberries to prevent diseases

Before protecting bushes from worms in berries and diseases, it is necessary to determine when it is best to carry out treatment. Experienced gardeners recommend treating the 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 carried out, since the daily temperature can drop below five degrees Celsius.

You can also treat plants in the fall, after the leaves have fallen. At the beginning of November, branches that have stopped bearing fruit are cut off from the bushes, and the most weakened shoots are removed. Only after preliminary pruning is preventive treatment carried out.

The best treatments and treatments

To choose the most effective product for working with raspberries, you need to figure out what is best to spray them with.

Store products

Quite often, store-bought chemicals are used to protect raspberry seedlings from diseases and insects. Effective drugs that can treat raspberry bushes include:

• "Mikosan." Used to increase the immunity of seedlings.The product contains components that help quickly get rid of pathogens of fungal diseases.
• "Healthy Garden" The drug is used to protect berries from aphids, sawflies and other dangerous pests. The product is sodium-based and sold in the form of soluble granules.

Folk remedies

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

Copper sulfate

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 your own vitriol solution. For therapeutic and prophylactic purposes, a slightly concentrated mixture is used. To prepare it, add 150 grams of the substance to 8-9 liters of warm water. Then everything is stirred for 5-10 minutes and infused for half an hour.

When spraying seedlings with vitriol, wear 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 or animals nearby.

Iron sulfate

During flowering and when fruiting begins, you can use iron sulfate. It is used for the following purposes:

• saturation of the soil 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;
• protection from insects.

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 per season. Raspberries are processed in the evening or morning, when there is no sun.

Boiling water

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

• eliminating the bud mite and protecting seedlings from this dangerous parasite;
• cleaning seedlings from spores that can cause powdery mildew;
• an increase in the number of peduncles, which increases the yield;
• eliminating aphids, which often attack raspberry bushes.

Before spraying a raspberry bush, you need to protect its root system from boiling water. To do this, the surface of the soil is covered with polyethylene, which will prevent hot water from entering the soil.

Urea

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

• Preliminary preparation. Before processing, the soil around each bush is loosened and weeds are cleared.
• Choosing a day to carry out work. The garden raspberry bush is treated with urea on sunny and windless days.
• Compliance with safety rules. When working with the solution, you need to wear rubber gloves, safety glasses and a mask.
• Preparation of the mixture. Add 750 grams of urea and 50 grams of copper sulfate to a bucket of water.

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

Bordeaux mixture

Most often, this remedy is used when biological products are not able to protect the shrub. Autumn is considered the best time to use Bordeaux mixture. During this period, the bushes have completely completed their growing season, and therefore the product cannot harm the plants.

To prepare the product yourself, add half a kilogram of lime to three liters of water. After this, another two liters of warm water is poured into the container. Then 40 grams of copper sulfate are added to 10 liters of boiling water, after which the mixtures from the two containers are mixed and left 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 people use it to increase the amount of sugar in berries and improve their taste.

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

Ammonia

Some people believe that ammonia is used only in medicine, but this is not so. It is used in gardening as a fertilizer and helps fight common diseases. Also, using ammonia solutions, you can protect seedlings from the following insects:

• ants;
• flower midges;
• mole cricket;
• aphid.

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

Tar

Tar, which has a pungent odor, is often used to repel insects. Shrubs are processed twice - before and after flowering. When creating the product, add 2-3 fly in the ointment to 10-15 liters of water.

Raspberry diseases and methods of combating them: timing and technology for processing bushes

If you do not care for shrubs well, they begin to get sick and die. It is recommended to familiarize yourself with the characteristic features of common raspberry diseases and methods of treating them.

How to treat raspberries against late blight (root rot)

The main reason for the appearance of root rot in shrubs is high levels of soil moisture. The main symptoms of late blight include black plaque on the pistils, mold and yellowing of the foliage. Also, the flowers of diseased bushes become deformed and dry out.

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, use half a liter of liquid.

Root cancer

The disease appears due to bacteria entering the root system of a raspberry seedling. The disease is accompanied by growths on the root collars and the lower part of the stem. The leaf blade becomes covered with yellow spots, which darken over time. Root cancer develops very quickly and therefore, when the listed symptoms appear, it is necessary to begin treatment.

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

Root rot (phytophthora)

Late blight is a dangerous disease caused by a fungus that develops in conditions of high humidity. Each leaf of a diseased seedling begins to turn red and dry out at the edges. If late blight is not treated, the shoots dry out completely. There are several remedies against root rot:

• Chalk. 10 grams of chalk are mixed with 400 milliliters of water and 5 grams of copper sulfate. The solution is applied to 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

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

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

Verticillium wilt

July is the month when raspberry bushes begin to suffer from verticillium wilt. The danger of the disease is that it slows down 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 to prevent raspberries from becoming sick with verticillium wilt. To do this, the bushes are regularly sprayed with fungicidal preparations and urea.

Chlorosis

The development of chlorosis on raspberry bushes is indicated by yellow spots on the leaf blade. This viral disease is very dangerous because it is not easy to get rid of. Chlorosis leads to slower ripening of the crop and drying out of the berries.

To protect the berries from 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 methyl emulsion, which is sprayed on raspberries two weeks before flowering.

Rust

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

Products that treat rust 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.

Infectious chlorosis

If there are yellow spots on the raspberry leaves, there is a high probability that it has contracted infectious chlorosis. At first, yellowing appears near the veins, but gradually the surface of the leaves is covered by one large yellow spot.

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

Mosaic

Mosaic appears on bushes after an attack by aphids, which are considered the main carrier of viral pathogens. A characteristic feature of the disease is 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 bushes should be watered with Kemifos and Fufanon.

Curly

As curl develops, the trunk of the bushes darkens, and the raspberry shoots shorten and bend at the edge. If the disease appears in the fall, all leaves acquire a bronze tint and begin to die. If curliness is not treated, the bushes will stop growing. Fungicides and copper sulfate are used to treat the disease.

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 fertilizers and the use of infected tools.

To quickly get rid of fungal pathology, diseased stems of bushes are cut off and potassium and phosphorus fertilizers are added to the soil.

Septoria (white spot)

Due to septoria, spots appear on the surface of raspberry leaves that are white with a brown border. Gradually, the spotting moves 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 bushes, after which the raspberries are sprayed with fungicides.

Didymellosis (didimella)

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

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

How to treat raspberries against pests

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

Raspberry beetle

The main cause of wormy raspberries is the raspberry beetle, which attacks the bushes. The insect becomes active 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 cannot be sprayed with chemicals. The only thing you can do with it is to collect it by hand.

Stem gall midge

Rot on young berries may appear due to attack by stem gall midges. Adults lay eggs on leaves, from which caterpillars then emerge. A young gall midge bites into raspberry stems and eats them from the inside.

Stems into which pests have penetrated will have to be completely cut out and burned.

Stem fly

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

To prevent the fly larvae from spreading throughout the plant, the affected shoots are cut out, after which wood ash and vitriol are added to the soil.

Raspberry mite

It is difficult to notice this insect in a timely manner, since its length rarely reaches one millimeter. Raspberry mites can be detected only when they have covered the entire bush. Manual collection of insects will not help get rid of mites and therefore you will have to use preparations for spraying raspberry seedlings. Effective remedies include Nystatin and Trichopolum.

Spider mite

If there is cobwebs on the raspberry stems, it means that the raspberry bush has been attacked by a spider mite. Also, the appearance of a mite is indicated by an oily coating located on the back of the leaves. Most often, the tick bug appears in May, so 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 leaves and lays eggs on them. The insect becomes active during the flowering period and penetrates flower buds to eat them from the inside. The main preventative measure for the appearance of weevils is regular inspection of the leaves and removal of deposited larvae.

Bud moth

If a brown butterfly flies near the bushes, it means that the plant has been attacked by a bud moth. 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 from them. This leads to a slowdown in further development of shoots.

leaf roller

Leaf rollers lay larvae on the inside of raspberry leaves. Young individuals feed on the sap of the leaves and penetrate the fruits, causing the crop to become rotten and wormy. The leaf roller attacks plants from the end of May to the first half of September.

To eliminate pests, an effective folk method is used - wormwood decoction with the addition of tomato tops and tobacco.

Raspberry moth

The raspberry moth gets into the shoots of shrubs, which is why their growth stops and overgrowth develops. Also, moth larvae can penetrate ripe berries and spoil them. All drying stems that are affected by the insect are cut out and burned.

Leafhopper

This is a small pest that attacks raspberries and vegetables. You can detect leafhoppers on raspberry bushes by light spots on the surface of the leaves. Many people believe that such insects cannot harm raspberries, but this is not true. If you don't get rid of them in time, the bush will dry out. Fungicidal agents, 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 glass beetle lays eggs at the bottom of the stems so that the larvae can penetrate to the roots. Shoots infected with glasswort stop bearing fruit and developing. A white powdery coating appears on them, which rots over time.

Conclusion

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