How to treat currants from pests and diseases?


The annual harvest of currants depends on whether it is sick or not. Processing currants from diseases and pests allows you to get a good harvest. Since summer processing is not always possible, experienced gardeners carry out work in spring and autumn. The article will describe how to treat currants from pests and diseases, as well as the land around the bushes.

Spring processing of currants

In the spring, along with the currants, dangerous insects awaken and diseases are activated. Awakened plants, which have not yet had time to grow stronger, are easy for them to sacrifice. For this reason, the bushes are so sick until summer. Only one method can cope with this problem - timely spraying.

Important! Postponing treatment when signs of disease or insects do not appear. The diseased plant is weakened and therefore there is a risk of secondary damage by other diseases.

Many gardeners are wary of spring processing, as they believe that it can spoil the future crop (chemicals, though). But it is not. For a start, there are many biological products (for humans, they are not harmful), but you can use folk recipes. In addition, if you choose the right tool, it will only positively affect the taste of future berries. But before describing how to treat currants from pests and diseases, it is worth figuring out when to do this.

Important! Popular recipes are effective only at an early stage of a lesion or as a preventive measure. If the problem is significant, it is worth solving with biological and chemical preparations.

Spring processing usually falls on the period when the kidneys have only started to swell, but have not opened. The weather should be warm outside. Wind, drizzle should not be. Spraying after or before the rain is meaningless, since moisture will simply wash away the product, and the procedure will have to be repeated.

Proper treatment of currants in the fall helps protect the bush from insects and diseases that may try to “winter” on it. If it is not carried out, the chance that the culture will be infected by something, increases by 2 times. It is necessary to carry out it regardless of whether the culture was sprayed before the summer, because in a couple of months the substances had already disappeared or were washed away by the rain.

Important! If there are signs of the influence of insects or diseases, a one-time treatment will not help - it is worth holding it 2-3 times with breaks of 1-1.5 weeks.

Autumn processing is carried out after the last crop is harvested and the currants are cut for the winter. Only then can you start work. This allows you to cover the maximum area of ​​the branches and the root zone.

It is believed that the treated plant gives the next year about 25% more yield. So the gardener's work pays off. A healthy bush can also be transplanted to a new place in the spring without fear that the procedure will lead to its death or infection of healthy plants that will grow close to it. How to treat currants from pests and diseases in the fall and spring is described in the subsequent paragraphs of the article.

Funds for currant bushes

What is the soil treated?

Not only currants, but also the soil around it needs care.

  1. About once a month, the soil should be loosened or dug up, but so as not to harm the roots.
  2. Any weed grass growing under bushes should be removed on time. Since weeds carry diseases and pests.
  3. In autumn, the ground must be mulched with peat or humus. This is a good frost protection for the roots, as well as an obstacle through which it will be difficult for the insects to cross (they live mostly in fresh manure and not in humus).
  4. It is possible to scatter wood ash under the currant with a thin layer. For insects, it is unpleasant, and for some it is dangerous, therefore it will reduce the risk of infection through the ground.
  5. To prevent viruses and fungi from "wintering" under a currant, for the winter the land around it is watered with Bordeaux mixture (100 g / 10 l of water) or potassium permanganate. Sometimes for the prevention of the procedure is carried out in March. Copper sulphate can also be used (50 g / 10 liters of water).
  6. It is important to fertilize the culture in a timely manner. Potassium, nitrogen, phosphorus ("Superphosphate", "Ammophosca", "Potassium Sulphate") are added in the right quantities For a plant, it is not only a growth stimulus, but also an increase in the immune system. A strong bush will be able to withstand the disease or "attack" of insects, and a weak one will most likely die quickly.
