How to detect and treat strawberry verticillary wilt – one of the most dangerous crop diseases

Tell me how to treat the verticillary wilting of strawberries and is it possible to save it at all? I noticed something strange in the spring, when the bushes were already blooming – the leaves began to dry. The weather was hot, so I decided that there was not enough moisture. But watering the situation did not change, even, in my opinion, it became worse – the berries were almost all rotten. Realizing that I have nothing to count on the harvest, I processed the strawberries with Fitosporin. As a result, by the fall, almost all of my plantation had dried up. Is there a chance to save at least these remnants, maybe to process something back in the spring? The variety is good, large and sweet, I would like to keep.

strawberry verticillary wilt Every gardener is periodically faced with various diseases of strawberries and other berries. Wet weather, cold summers, fungi and viruses – there can be many reasons and it is very difficult to insure against all of them. But the most dangerous and complex disease is strawberry verticillary wilting. Moreover, it is dangerous not only by the affected area, which can go much further, beyond the berry. First of all, the fungus is dangerous in that it is impossible to notice it at the initial stage, which means that it is impossible to react in a timely manner. Only when the disease affects the aboveground part, it becomes clear that the culture is sick. But it is also difficult to determine what exactly, because similar signs and in fusarium.

Strawberry verticillary wilting – signs of the disease

signs of strawberry verticillary disease The culprit is the very viable fungus Verticillium albo-atrum. For many years (up to 15), its spores can be in the ground and wait for favorable conditions to begin to develop. But when this happens, the fungus enters the plant through the root system, from the inside. Growing up, it destroys the tissues that feed the aerial part, while releasing toxic substances. This leads to the complete destruction of plants. But even after the death of its, so to speak, epiphyte, verticillium continues to live. He hits the ground again and everything repeats again.

At the initial stage, when the fungi only penetrate the roots, and it would still be possible to save the strawberries, it is impossible to detect the problem. External signs appear closer to the harvest season:

  • lower, old, leaves, wither, turn brown and dry out;
  • fewer young leaves appear, they are small, twisted;
  • whiskers and petioles may be covered with dark (or bluish tint) spots;
  • petioles turn red;
  • young roots turn black and slow down in development;
  • old roots are destroyed, become loose;
  • plants droop, become small (dwarfism), foliage is also small and yellowish.
