Biological methods of struggle

Gall leaf aphid lays eggs under the bark of the plant before the onset of cold weather, which must survive the winter. In the spring, with the appearance of the first leaves, pests hatch from the masonry and begin to destroy the currant bush.

To prevent the appearance of gall aphids, the plant is watered with boiling water. It awakens sleeping kidneys and destroys wintering eggs.

On a note!

Water for processing the bush is heated to a temperature of 50-60 degrees.

Aphid control methods include cutting infected shoots. Branches damaged by a pest are burned in a fire.

Useful insects are attracted to the site: ladybugs and lacewings. To do this, nectariferous flowers are planted next to the currant:

  • oregano;
  • marigold;
  • Daisies
  • dill;
  • anise.

To prevent plants from attacking red gall aphids, dill, onion, tomato, coriander are planted next to them.

Leaves need to be hosed. A strong pressure of water will bring down aphids and ants from them. Watering should be done on a cloudy day or early in the morning until the sun begins to bake.

If the plant is too infected and no drugs act on it, then the bush should be cut in the fall "under the root" or completely dig it out. Dug up the earth must be sprinkled with ash or tobacco.

Aphid Prevention

Gall aphids on red currants will not appear if timely preventive measures are taken.

If you suspect the appearance of aphids, carefully wash the leaves with a soapy solution. It clogs the skin of the aphids and it cannot breathe. Processing should be carried out every evening for a week to kill hatched individuals.

On a note!

For a soap solution, they take a bar of tar or laundry soap, rub it on a fine grater and fill it with 10 liters of warm liquid.

Keep the ground near the bush clean. You need to remove all weeds and mulch celandine, which is poisonous to aphids.

The following measures must be taken to protect the plant:

  • destroy anthills;
  • spread the adhesive tape pieces near the bush, with the adhesive side up;
  • provide the plant with sufficient watering;
  • inspect leaves and shoots.

It is necessary to monitor the top dressing of the bush. Nitrogen fertilizers reduce the plant's ability to resist pests and diseases.

Near the currant bushes, it is necessary to plant aromatic herbs that attract ladybugs and scare away ants and aphids. These are marigolds, anise, dill, onions.

Good results can be achieved if all the methods are brought together: prevention, chemical and folk control measures. It is not always possible to get rid of aphids in one year. There may be eggs under the bark, from which new individuals will appear. But if you do not give up, the pest will completely disappear.

      Not quite boiling water is needed. The article also says 50-60 degrees. This temperature is beneficial for the plant.

        Andrei, I pour practically clean boiling water right away from the stove. The stove stands on the street, I warm the water with wood, and immediately, into a watering can and forth. I water in late autumn, at the end of November. I haven’t cooked anything yet. By the way, there are many videos on the Internet how to do this.
