    one common misconception that can only lead to new troubles. We are talking about the fight against viruses in the following way: supposedly it is necessary in the fall, after the appearance of light frosts, to pollinate the ground with quicklime (fluff) and, if possible, repeat this procedure in the spring. I would not advise doing this under any circumstances, since applying lime directly under the potatoes can contribute to the development of scab. If you really want to use fluff, then it should be applied only under the culture preceding the potato.

    But the selection of tubers for planting is of paramount importance. And it must be carried out even during harvesting, choosing tubers of the correct shape for seeds, with characteristic features of the variety, taken from under the most productive and outwardly healthy bushes. In science, this is called clone selection. By applying it constantly, you can extend the life of any variety.

    about diseases that potatoes are susceptible to, and about methods of combating them.
    The widespread idea that complexes of certain agricultural techniques can cure a potato from all misfortunes is not entirely true: in this way you can only get rid of fungal misfortunes, but not viral ones. Because in this case, the carriers of the ailments live in living plant cells, and no treatment of the soil and tubers can get rid of them. Therefore, the frequently encountered advice to plow to the full depth of the arable layer in order to warm up the earth as much as possible and thereby destroy viruses will also not lead to anything good.

      - Judging by the description, the potato is infected with phomosis (button rot, gangrene of tubers). The causative agent of the disease is a mushroom. Infection occurs in the field during the formation of tubers, as well as during harvesting.
      Phomosis usually appears a few weeks after harvesting. The peak of the disease occurs in January-April. By spring, the tubers completely rot.
      The first signs of phomosis are dark spots of a vague form on the leaves of plants. On the stems you can observe small growths in the form of balls. However, symptoms may be less noticeable if you use late blight protection because they inhibit the development of phomosis. In order not to encounter a problem this year, I recommend a set of preventive measures:
      - Do not plant infected tubers, as the causative agent remains in them;
      - before planting for about half an hour, warm the tubers in a warm solution of a copper-containing preparation;
      - plant potatoes, taking into account crop rotation rules, since the causative agent of the disease can persist in the soil;
      - after harvesting, remove all plant residues from the site;
      - hold the part of the crop that you plan to plant in the future, IQ-20 days in the open air, which will help the potato to clear itself of infections hiding on the surface of the tubers and improve their keeping quality.

    The main symptom of infection of potatoes with viruses is the appearance of filamentous sprouts during germination. If the proportion of such tubers prevails, the planting material must be urgently replaced.

    Currently, potatoes infect more than 20 viruses, which, having accumulated, cause shredding, stiffening of tubers and lower yields. On the leaves, the diseases manifest as mottled, mosaic, waviness and curling of leaves, yellow dwarfism. Infection of healthy plants occurs as a result of mechanical damage during planting, when caring for plants and harvesting. The main carriers of viruses during the growing season are sucking insects, such as aphids, cicadas, wireworms and, of course, the Colorado potato beetle.
