Despite the fact that modern raspberry varieties are more resistant to various kinds of diseases, lesions of individual bushes or whole raspberries are still happening. So, every gardener just needs to know not only how raspberries are grown, their diseases and their treatment - a topic no less important for those who want to achieve high results in terms of yield and taste of berries.

What measures can prevent the occurrence of diseases

Although raspberry is not a very whimsical plant, its planting should be carried out in accordance with the standards.

1. The distance between the bushes should be at least 60x100 cm, increasing the density will worsen the ventilation and lighting of the stems.
2. The raspberry should be located on elevated, not swampy areas.
3. The recommendations for seasonal pruning of raspberry bushes should not be neglected.

Significantly reduce the risk of plant morbidity:

• timely fertilizing of the site,
• carrying out preventive measures for plant protection.

Virus infections are most dangerous for raspberries, for their development they use living plant cells and spread with extreme speed raspberry pests, such as: aphids, nematodes, and cicadas. You can bring the disease with infected planting material, even non-sanitized garden tools can become a source of the spread of the disease on the site.

Infection of raspberry bushes in the first years will give a significant decrease in productivity, and ultimately, after a few years, will lead to the death of the bush. At present, there are no sufficiently effective measures to combat viruses, i.e. when a disease is detected, it is necessary to completely remove the infected plants and burn them. Therefore, all efforts should be directed to preventive work, paying particular attention to the control of pests that transmit diseases.

Experienced gardeners do not recommend planting raspberries in the place where plants with viral diseases were detected.

anthracnose

This fungal infection is common, it affects all parts of the plant, including young shoots. The disease can be diagnosed by gray spots with a purple border on the leaves, the tendency of the spots to merge, curl the affected leaves and fall off. On the branches, the disease manifests itself with gray depressed spots, merging they turn into cracks and ulcers on the cortex. Affected berries become brown and dry.

Since there are no varieties completely resistant to anthracnose, you should pay attention to those that are least affected by the disease: Usanka, Texas, Cuthbert, Izobilnaya, Turner, Herbert.

Recommendations for the fight against anthracnose:

• planting varieties that are more resistant
• compliance with planting density,
• avoidance of excessive soil moisture,
• complete destruction of affected plants,
• autumn application of potassium phosphate fertilizers into the soil,
• before budding, treatment with a 1% solution of Bordeaux fluid or a solution of copper chloroxide (30 g / 10 l of water).

septoria, or white spotting

It occurs as often as the disease described above, has a fungal origin, often affects wild raspberries, and is easily transmitted to cultivars. It is expressed in the appearance of light spots with black dots on the leaves (fungal pycnidia), causes drying and falling of leaves, stems appear. The disease is activated with high humidity.

Varieties that can withstand the disease: Kaliningradskaya, Turner, Novosti Kuzmina, Volzhanka, Marlboro, Russkaya, but the full resistance of the varieties is also not guaranteed.

Prevention of Septoria:

• careful selection of planting material,
• refusal to plant varieties that are unstable to this infection,
• timely cleaning and burning of leaves,
• sufficient thinning of bushes and removal of all diseased and weak shoots,
• spraying with Bordeaux liquid or copper chloride, Tsineb, in accordance with the instructions, in early spring and late autumn.

Experienced gardeners argue that in order to preserve the desired raspberry variety, it is enough in the spring to separate from the root of the infected bush a part of the root with an shoot bud - the bush grown from such planting material will not be infected with white spotting.

rust

The reason for its appearance is the defeat of the Phragmidium rubi - idaei Karst fungus, leaves, petioles and shoots suffer from it, the symptoms are the appearance of small orange or yellow tubercles on the leaves. Then rusty spots appear, exuding pustules of summer spores, which can infect new plants. The pathogenic fungus overwinters in the tissues of the branches and roots of the affected plants. Cases of rust damage become more frequent with high humidity.

Experts do not recommend planting such varieties of raspberries in areas infected with rust: the Golden Queen, Cuthbert, Marlboro, Latham - they will serve as a constant source of the rust pathogen.

How to prevent the appearance of rust:

• use exceptionally healthy material for planting,
• avoid planting varieties susceptible to a fungal infection of this species,
• remove and destroy diseased bushes without leaving rhizomes,
• remove all fallen leaves from the plantation, dig the soil between rows,
• treat with 3% nitrofen solution or 1% DNOC solution in early spring, and the entire bush, basal area and aisles should be treated,
• before flowering and after harvesting, raspberry bushes should be sprayed with a 1% solution of Bordeaux mixture.

purple spotting

Its main sign is the appearance of lilac-brown spots with fuzzy outlines. Their growth causes damage to the kidneys and leaves and leads to their massive drying. Harvest dies before the berries ripen. The disease has a fungal origin and is spread by spores. Wintering of the fungus occurs on infected stems. The development of the fungus occurs throughout the growing season and even in winter, if the temperature does not drop below 0 C. Contribute to the increased spread of infection, increased humidity and the invasion of a known plant pest - raspberry gall midges.

The fight against purple spotting is:

• planting varieties less susceptible to infection by fungi,
• the destruction of all parts of diseased plants,
• observing planting density and ensuring adequate ventilation,
• preventing excessive watering,
• digging the soil in the fall with the introduction of a sufficient amount of potash and phosphorus fertilizers,
• three times spraying with copper chloride or Bordeaux mixture.

Preservation of the variety is possible when the offspring with root fragments are separated from the infected bush and transplanted to a safe place.

autumn spotting

This disease of raspberry leaves can occur since mid-summer, it is observed everywhere where raspberries are planted. Heavy rains and high air humidity provoke a surge of the disease; in rainy weather, spores of the fungus multiply very actively. Shapeless spots appearing on the surface of the leaves cause loss of leaf viability, and most importantly, they prevent the laying of fruit buds, which leads to a significant decrease in raspberry yield for the next year. Botanists have not yet provided information on which of the raspberry varieties can withstand the disease.

Control measures:

• since the pathogenic fungus hibernates on the leaves, the area occupied by the raspberry should be carefully cleaned of fallen leaves, all the garbage collected on it should be burned,
• in early spring it is required to spray raspberries with a solution of nitrophene (3%) or copper sulfate (4%),
• treatment during the growing season is the same as for Septoria or Anthracnose.

raspberry root and stem cancer

The nature of the disease is bacterial, the area of \u200b\u200bits distribution is all natural zones. Symptoms - the appearance on the roots and stems of tumors up to 3 cm in diameter. Then there is a fusion of tumors, roughness and cracking of the upper layer of the cortex appears. Cancerous tumors deplete the plant and during the winter it dies. Ill plants change the color of the leaves to yellow, the taste and aroma of the berries is lost. If you do not take measures to combat the disease, then it will progress very quickly.

How to deal with raspberry cancer:

• all diseased bushes should be removed from the area and burned,
• planting new raspberry bushes at the site of the sick is not recommended for the next 4 years,
• if there was a massive defeat of plants, then you will need to find a new platform for planting raspberries,
• before planting new healthy bushes, you should treat the entire soil with a solution of 1% copper sulfate,
• it is advisable to treat the roots of seedlings with the same solution for about 5 minutes.

Advice from experienced gardeners: if your raspberry has an increased susceptibility to fungal infections, you should limit the application of nitrogen fertilizers to the soil. Mulching the territory of raspberries with manure will help defeat the emerging rust.

Raspberry - a treatment for pests and diseases that they carry

In addition to the above fungal diseases, there are a number of such ailments of raspberries that carry harmful insects. Naturally, the first control measures and the most effective prophylaxis against such diseases will be actions to kill harmful insects, in particular such as aphids, nematodes, and cicadas. So, we will consider how to process raspberries from pests and diseases.

aphid

Raspberry Chlorosisdistributed by aphid larvae, expressed in the grinding of leaves and berries, a change in the natural color of the leaves, inhibition of shoot growth.

As a fight, you can offer:

• the destruction of aphids
• avoiding watering raspberries with cold water,
• the use of insecticides that affect aphids at all stages of its development,
• removal of diseased plants and their destruction,
• limit the application of fertilizing containing potash and phosphorus fertilizers,
• refusal to introduce fresh manure and superphosphate,
• use nitrogen and humus, compost and peat as fertilizers, you can pour bushes with a solution of bird droppings diluted in a 1:10 ratio with water,
• too wet areas should be drained,
• if the soil is highly acidic - should be applied to each square meter of about 100 grams of gypsum.

Unparasitic raspberry chlorosis can cause adverse weather and lack of trace elements in the soil.

Aphids are a carrier of raspberry disease such as mosaic. It is expressed in the appearance of mottling on the leaves, especially in the autumn period. It leads to the acquisition by the leaves of tuberosity, while the berries are smaller and dry, the root shoot is inhibited in development.

Aphid causes development curly raspberries. The disease tolerated by aphids leads to the growth of irregularly shaped leaves, the modification of buds and flower brushes, and reduced yield.

In the middle zone of Russia, aphid is a fairly common pest, it happens in two types: shoot and leaf. Aphids are quite dangerous for plants and require adequate control measures: spraying with chemicals Fufanon, Actellik or Intavir before flowering and after harvesting berries.

nematodes

The development in the soil of too many nematodes can cause the appearance of signs on plants ring spotting. The disease manifests itself only in the spring or in the fall, manifested by the formation of yellow spots on the leaves. The defeat of the virus leads to the weakening and death of plants. The fight against this raspberry disease is to treat the soil with nematicides. It is also not recommended to plant raspberries after peas, beans or beans, it would be better if tomatoes, cabbage or strawberries would be its predecessors.

cicadas

They are carriers of mycoplasma-like disease - bushy raspberries, expressed in the underdevelopment of shoots and the termination of fruiting in the next year after infection. An effective method of combating cicadas is spraying bushes with 0.25% emulsion of malathion during the stage of nymphs.

raspberry beetle

It can cause irreparable damage to the crop - its larvae eat the fertility and drupes of berries, from which they become worms. You can prevent the mass appearance of raspberry beetle by spraying plants during the appearance of buds with a solution of chlorophos (0.3%) and autumn digging of the soil.

beetle or raspberry weevil

Raspberry weevil is a black beetle gnawing holes on buds and developing leaves. The invasion of weevils can lead to the death of 50-80% of the buds. As a preventive measure, spraying with a solution of chlorophos (3%) is used.

gall midges

The same measures, spraying with a 3% chlorophos solution, are required to be carried out against gall midges, or raspberry mosquitoes. The insect larvae, concentrating in the cracks of the cortex, actively feed, which leads to the appearance of deep wounds that cause the death of shoots in the winter.

Especially severely damaged raspberries with cracking bark, because at the sites of lesions of gall midges, an increased development of fungal diseases is observed. A slight damage to the shoots can cause the death of only part of the crop. A good effect is mulching the soil around the bushes with a thick layer of peat.

raspberry fly

She appears in mid-May, lays testicles in the tops of shoots. The larva that appears after a week makes moves under the skin covering the shoot - this leads to drying out of the apex. Wintering of the larva occurs in the soil. The fight against raspberry flies consists in digging the soil under the bushes in the fall, mulching with peat in the summer, treating the bushes with a 3% chlorophos solution.

Now you know what the most dangerous pests of raspberries are, the fight against them will be effective if the recommended measures are taken in an integrated and timely manner. Only in this case will it be possible to maintain plant health and obtain a quality crop.

How to get rid of raspberry pests in folk ways

As for the popular methods of pest control, the following can be recommended. From aphids:

Spraying plants with a solution which includes:
  2 l of chamomile infusion (1 kg of dry grass pour 10 l of boiling water, leave for 12 hours),
  30 g of laundry soap
  tobacco infusion (1 kg of tobacco leaves and waste is poured 10 liters of boiling water, insisted for a day, then diluted 2.5 times with water)
  10 liters of water.

You can spray:
  decoction of wood ash (300 g of ash per 10 liters of water),
  a decoction of pink mustard (1 kg of leaves is boiled for 10 minutes in 10 l of water, then add 30 g of laundry soap),
  infusion of onion and garlic husk (200 g of husk in 10 water, leave for 5 days),
  ground garlic solution 200 g per 10 l of water.

To combat ticks and aphids, you can use a decoction of fresh potato tops (1.5 kg per 10 liters of water, withstand 4 hours).

Plants should be sprayed 3-4 times, every 15 days, starting with budding. Decoctions and infusions are used on the day of preparation, spraying is best done in the evening. Although these solutions are not toxic to humans, they should not be allowed to get into the eyes.
