Currant leaves curl: why, what to do and how to process?

When growing different crops in their plots, the main task of the gardener is to obtain from them tasty fruits and a bountiful harvest.Such indicators depend mainly on the condition of the seedlings. It does not happen that a sick currant bush gives great harvests, and therefore it must be properly looked after throughout the season.

In that case, if the currant leaves curled, then it is hardly possible to get a big harvest. When a pathology appears on a plant, it is necessary to first find the reasons why this occurs, and then take the necessary measures to eliminate the problem.

When the currant is unwell, the leaves curl or redden, it indicates that the plant has a certain disease. Because initially it is important to correctly determine the nature of the damage. The most common diseases that affect the bush during the flowering and fruiting season are fungal infections and pests. As a result, curliness appears on the plant and twisted leaves die off.

When the top young shoots are curled up, twist or turn yellow, then the cause can be spherotek. The leaves will be covered with bloom and gradually become brown, while gradually drying out. When the leaves frown, they fold inward. In this case, you will not be able to get a good harvest from the bush. Pathology can affect the plant in the first days of spring, when it starts to warm up outside. The optimum temperature for the appearance of the disease is 20-25 degrees and the humidity of the air is up to 100%.

Anthracnose is also a cause of defeat bush. When such a pathology occurs, it appears brown spots on the leaves. As a result, they begin to dry and fall prematurely. Similar manifestations can be on the cuttings. The optimal time for the appearance of such pathology is June. If there are favorable factors, the infection will begin to spread rapidly throughout the plant and hit it entirely. Favorable condition for the emergence of pathology is a strong soil moisture around the bush.

Usually, the disease occurs before the appearance of the fruit. As a result, they develop poorly and their quality deteriorates.

Currant may be affected by columnar rust, which appears as orange spots on green shoots. By autumn, they turn brown, a month after their appearance, the leaves fall. Spores can winter on the leaves, and manifest in spring. This pathology is most often found in those areas where currant processing is carried out industrially.

Currant rust can occur at the time of swelling and bud formation. At this point, yellow spots will appear on the shoots. Then these leaves will crack and swell. Gradually, the green shoots will fall off and crumble. Spores of infection can affect the entire plant and winter it. Favorable weather for breeding infection is a rainy spring.

When currant leaves are wrapped, a spider mite that spreads through the plants with the help of wind can cause this. This pest, falling on a bush, begins to make a cobweb there, which negatively affects the leaves. In places of lesions appear specks of red, which then fade. Currant suffers from this, its fertility decreases.

When it gets warmer, they climb back to the bushes and start laying eggs. Larvae can be seen in the spring on the leaves. With a dry summer, the female can reproduce 10 generations in a season. The best time for this is the middle of summer. By autumn, the larvae grow and go to winter in the soil under the plant.

The currant glass bowl is a butterfly with transparent wings and yellow stripes on its belly. This insect is affected by plants 10 days after the beginning of their flowering. The insect lays eggs, from which caterpillars then appear, and they damage the leaves.Next, the parasite moves to other shoots and gradually slides down the bush. The affected branches dry up.

Currant leaf gallitsa - small bug with wings. Such parasites appear on the young leaves of the currant, which gradually begin to deform and become red. The most common pest on young seedlings. Over the summer, he is able to reproduce 4 generations. Winters in the ground under the bush. Laying eggs at the time of the appearance of flowers. As a result of the defeat of the leaves, they begin to gradually die off.

It does not have wings, and therefore can not move long distances. She winters in eggs, which the female lays in the fall. The larvae themselves appear in spring. A colony of parasites damages the bush during bud break, causing them to rot. When the currant stops growing, the aphid is transferred to other weeds that are near the bush. In autumn, the female returns to the currant bush and lays eggs there.

If a black currant has a problem, you need to treat it and fight the parasites using different methods. To do this, you can treat the bush with various preparations, as well as spray it correctly. It is necessary to do such procedures immediately when the pests appear, and not when the leaves are already curled. In this case, the treatment will be positive. Control measures and means should be chosen depending on the type of pathology. Currant bushes are often affected by diseases during fruiting, and therefore it is recommended to use products that do not harm the berries. All protective measures must be carried out according to the calendar.

When budding occurs, then against the appearance of the main fungal pathologies on the bushes, it is recommended to spray them with Bordeaux composition. To do this, prepare a mixture of low concentration.

When the flowers appear and the first brushes, then another treatment with Bordeaux mixture is carried out against fungal pathologies. For this, its concentration is increased.

To prevent American powdery mildew from appearing on the plant, it is recommended to process it with a solution of Tiovit Jet. Such compositions are sold in stores. Dilute them in water should be in accordance with the instructions on the package, observing the dosage. When flowering has already passed, it is recommended to cut the soil under a bush in which the larvae are already located, and also to treat the bush itself with copper sulfate.

When the bush is prepared for wintering, it is recommended to once again process it completely using the same methods that were used during its flowering. In that case, if the plantations are large, then chemical treatments after flowering is not necessary. Often, experts use biological preparations to eliminate pathologies - Bitoxibacillin, Fitoverm, or Lepidotsid. Spraying is carried out two weeks after the harvest. If time to make such activities, it will provide an opportunity to eliminate the reasons for which the leaves are twisting.

In autumn, when leaves fall from a bush, it is recommended to collect and burn them all. You also need to cultivate the soil under the plant itself, as there may be spores and larvae that burrow into the ground to overwinter. If they are not removed, then the next spring, when it gets warmer outside, they will crawl out again and move to the bush.

It is necessary to mow the grass regularly near the currant bushes and not allow it to grow strongly. When planting a large number of currant bushes, it is necessary to keep a distance between them, which should be at least 80 cm. This will help them develop better and also prevent the movement of pests and diseases from bush to bush.Also, a large distance between the bushes will help the soil to dry better after rains and warm in the sun.

In order to prevent the occurrence of pathologies and cope with pests faster, experienced gardeners recommend periodically loosening and digging up the soil under the bushes themselves, without going too far in order not to damage the roots. When the first buds begin to appear on the shoots, they can be treated against pests with compounds that have a strong odor. In most cases, this uses solutions prepared from natural remedies that are in every home. This may be, for example, an infusion of wormwood or tobacco.

If it was not possible to preserve the integrity of the currant, as well as the soil under the bush, some experts use the method of transplanting them. Here, too, you need to follow certain rules and choose the right place for them.

They should be seated at a distance of at least one and a half meters. Also, if there are fences on the plot, then the distance from them to the bushes should also be at least 1.5 m. If there is not enough space for the currant or it is darkened, then a good harvest cannot be obtained from it.

During the whole period of rooting of seedlings at a new place, it is recommended to water the soil abundantly, as the plants love it. Watering is necessary once a week. If the groundwater is close and the soil is too wet, the root system will rot, and therefore it is recommended to constantly monitor the condition of the soil. In case of excessive moisture, it is recommended to stop watering and give the plant access to the sun.

For transplanting, it is necessary to choose young bushes and prepare a place for them in advance. The holes for planting young shoots must be at a depth of no more than 40 cm in order for the root to fit comfortably. In each well it is necessary to put 200 g of manure and ash, and sprinkle it on top with a thin layer of earth. Next, the bushes are lowered into the hole and flooded with water. After that, the hole is filled with soil to a height of 10 centimeters from the roots.

This will reduce stress and help the plant to settle down faster. Pruning is best done in the fall. Those who will transplant bushes to a new place should also remember that young currant bushes should be planted at an angle of 45 degrees and not buried deep in the soil. This is important in order for the root system to develop well.

Also, it will contribute to the rejuvenation of the bushes. A year after planting, it is necessary to form plants and leave only the branches growing up. Dry tops, if they were hit by frost, need to be removed. In this case, the bush will develop well and will be able to bring great harvests.

As you can see, with certain knowledge, as well as desire, you can save currants from diseases or pests. If you properly care for the bush, the currant itself will be able to withstand the main types of garden troubles and bring a great harvest. To do this, it is recommended to clean it regularly, water it, and also feed it.

Also spray if necessary. Observing such simple rules, you can get not only a big harvest. Berries will have a good taste, as well as the presence of a large number of useful elements in the composition. If you timely and fully take care of the plant, the bush will bear fruit for 5-8 years.
