  • currant leaf gall midge (small mosquitoes that feed on young, not unfolded leaves, disfiguring them);
  • currant goldfish (the beetle larva feeds on the core of the branches, the tops of the shoots begin to dry out);
  • currant kidney mite (mites colonize buds on plants, as a result of which they die);
  • spider mite (covers the leaves with cobwebs and sucks the juices out of them, the leaves turn yellow and die off);
  • currant kidney moth (damages both the kidneys and berries, the kidneys do not bloom and die);
  • gooseberry moth (the butterfly lays eggs inside the flowers, caterpillars emerge from them, which entangle the fruits with cobwebs and feed on them);

  • yellow gooseberry sawfly (green-blue larvae with black dots eat the leaves);
  • gooseberry moth (caterpillars eat up the entire leaf, leaving only the petiole);
  • currant glass (pink or white caterpillars gnaw through the core of the branches, the shoots dry up and die off);
  • gooseberry shoot aphid (sucks juice from the ends of the shoots and from the leaves, which curl up into a ball);

In the fight against goblet rust, a 1% solution of Bordeaux liquid is used: the first time when the leaves open, the second - after flowering, and the third - after 8-10 days.

The destruction of the spheroteka consists in spraying the bushes and soil with iron vitriol in a dilution of 10 liters of water - 300 g of the drug. At the first signs of illness during the growing season, the bushes are sprayed with soda ash (for 10 liters of water - 50 g of soda) with the addition of 50 g of soap. The treatment is repeated 2 or 3 times after 10 days.

Terry or reversion is a fairly common and dangerous disease. black currant... In this case, the plant becomes sterile, and pruning and other methods are powerless. If you notice that during the flowering period the flowers of the currant dry up completely, do not fall off for a long time and the fruit does not form, you need to uproot and burn the diseased bush. Terry is transmitted from one plant to another by bud mites, aphids, as well as the cultivation of already infected shoots.

For pest control, there are special spray solutions that you can buy at the store.

Prevention of currant diseases

Precautions, a kind of prevention, include the following actions:

  • digging the earth around the plants;
  • destruction of fallen leaves;
  • pruning.

Many diseases can be avoided with proper care of the bushes: in the event of a lack of moisture, the currants lose their greens, turn yellow, the berries crumble, and with an excess of moisture, root rot develops.

Lack of light leads to the fact that the berries ripen poorly and fall off, and excess light contributes to leaf burns.

Using healthy, disease-resistant planting material, you can avoid damage to currants by pests and diseases.

Some time ago, we had several huge bushes with currants growing in our garden. Then they were overcome by some kind of sore. The leaves turned yellow, rusted, curled, fell off. There are fewer berries. No matter how much mom tried to fight it, it all ended with the fact that they were completely removed.
