Red currant: diseases and pests

Reversion

This viral disease is also called mahrovost. All kinds of currants are ill. You can recognize by the bizarre shape of the flowers: the petals are made threadlike, making the inflorescence becomes terry. The virus settles in the juice of plants, so it is almost impossible to help the bush. If you find only a few mutilated inflorescences, you can cut off the branches on which they have blossomed, and if the flowers are mass-consumed, then the bush must be uprooted and burned.

It is often possible to find red spots on the currant , gray or dark brown.

Septoria

Fungus "draws" on leaves abstract compositions of specks with a brown border, on which are scattered black dots (spores). Help the plant can be sprayed with preparations containing copper. Affected branches should be cut.

Anthracnose

The leaves and shoots of the currant become dry, as if burned. In this case, the bush needs to be treated with fungicides (antifungal agents), for example Bordeaux liquid. Will help in the fight against the pest and copper sulfate.

Buckwheat rust

What else are fungal diseases of currants? Red spots on the leaves appear due to damage to the rust fungus. On the underside of the sheet, piles of "glass" are pressed like corrosion. Affected leaves and berries must be collected and thrown into the fire. After harvesting healthy berries, the bush is treated with copper-containing preparations. The same treatment should be done in the spring. The spring "shower" of mineral fertilizers (half a kilogram of urea or nitroammonophos, dissolved in ten liters of water) will serve as a good prevention. The insidiousness of the parasite lies in the fact that the fungus moves to winter on a nearby growing grass, and in the spring it returns to the garden culture.

In the autumn, red currants require special care. Diseases and pests often hibernate on fallen leaves and in the soil, so the land around the bush should be cleared and several times dug up.

Spheroteka

The disease, in which shoots and leaves are covered with a white coating, is also called powdery mildew. The unripe berries are wrapped in a felt layer and, of course, are not suitable for food. To save the currant, it is necessary to spray the bush with a special solution at the first signs of the spherote. For ten liters of water take 50 grams of soda ash and 40 grams of shavings of laundry soap.

Enemies among insects

The great harm to the currant is caused by aphids. In the spring, its larvae are selected from the kidneys, the colonies colonize the bush and suck the juices out of it. On the underside of the leaves red bubbles are bubbling, the shoots are curved, twisted and withered. Ants are bred by ants feeding on their sweet "milk". The control of aphids begins in the early spring with the processing of bushes and soil around them with a 3% solution of nitrophene (on a ten-liter bucket of water - 300 grams of funds). Help and decoctions of yarrow, horse sorrel, dandelion, marigold, as well as from tomato and potato tops. Spraying is excluded only during the flowering period of the currant and stops 5 days before harvesting.

Caterpillars of the currant gland gnaw through the core of the branches "tunnels", what is depressing the plant. Damaged twigs should be cut off immediately.

Larvae of gooseberry firefly braid the bunches of berries with a web and suck out the juice. Pest control consists in the autumn digging of the soil into which the pupae of the insect leave for the winter, and in the treatment of the bush before flowering the infusion of tobacco or tobacco leaves.

A generous harvest will be rewarded by its owner red currant. Diseases and pests will be neutralized by the skillful actions of the gardener, lovingly caring for his green pets.
