How to please the experienced gardener juicytransparent scarlet clusters that red currant shimmers under the summer sun! Diseases and pests, however, can not only deprive the bush of fruits, but also completely destroy it. Reasonable care of the plant from the moment it is planted will protect the berry. Shrubs should not be thickened, the optimal distance between them is at least two meters, then the plant is sufficiently illuminated by the sun, aired. Be sure to remove the old branches.
Red currant: diseases and pests
Reversion
This viral disease is also called terry.She has all kinds of currants. You can recognize by the bizarre form of flowers: the petals are threadlike, which is why the inflorescence becomes terry. The virus settles in the sap of plants, so it is almost impossible to help the bush. If you find only a few crippled inflorescences, you can cut off the branches on which they bloom, and if the flowers are smoked en masse, then the bush should be uprooted and burned.
Often you can find on the currant red spots, gray or dark brown.
Septoria
Fungus "draws" on abstract leafletscompositions of specks with a brown border, on which black dots (spores) are scattered. You can help the plant by spraying drugs containing copper. Affected branches must be cut.
Anthracnose
Currant leaves and shoots become dry,as if burned. In this case, the bush must be treated with fungicides (antifungal agents), such as Bordeaux liquid. Will help in the fight against pest and copper sulfate.
Glass rust
What other fungal diseases of currants exist?Red spots on leaflets appear due to rust fungus. On the lower side of the sheet are cramped like corrosion of a handful of "gossies". Affected leaves and berries must be harvested and thrown into the fire. After collecting healthy berries, the shrub is treated with copper-containing preparations. The same treatment should be carried out in the spring. Spring "shower" of mineral fertilizers (half a kilogram of urea or nitroammofoski dissolved in ten liters of water) will serve as a good prevention. The cunning of the parasite lies in the fact that the fungus moves to winter for close-growing grass, and in spring it returns to the garden culture.
In the fall, it requires special care to red currants. Diseases and pests often overwinter on fallen leaves and in the soil, so the ground around the bush should be cleared and dug up several times.
Sphereoteka
A disease in which shoots and leavescovered with white bloom, also called powdery mildew. Immature berries are shrouded in a felt layer and, of course, are not suitable for food. To save currants, it is necessary at the first signs of a sphere library to spray a bush with a special solution. For ten liters of water take 50 grams of soda ash and 40 grams of soap chips.
Enemies among insects
A huge damage currant does aphid.In the spring of its larvae are selected from the kidneys, colonies colonize the bush and suck juice from it. On the back of the leaves, red blisters are bumping, shoots are bent, twisted and dry. Aphids are bred by ants that feed on their sweet "milk". The fight against aphids begins in early spring with the treatment of bushes and the soil around them with a three percent solution of nitrofen (for a ten-liter bucket of water - 300 grams of money). Broths from yarrow, horse sorrel, dandelion, marigolds, as well as from the tops of tomatoes and potatoes will also help. Spraying is excluded only during the flowering period of currants and stops 5 days before picking berries.
The caterpillars of the currant glass gnaw through the “tunnels” in the core of the branches, which inhibit the plant. Damaged branches should be immediately cut.
Gooseberry larvae larvae twine around clustersberries and sucking juice. Fighting a pest consists of digging the soil in autumn, into which the insect pupae spend the winter, and treating the bush before flowering with an infusion of tobacco or tobacco leaves.
With a generous harvest, the red currant will thank its owner. Diseases and pests will be neutralized by the skillful actions of a gardener who lovingly cares for his green pets.
