White cucumber mosaic is the most harmful of all types of mosaics and one of the most resistant to treatment. The virus is difficult to destroy because it has the ability to persist for a long time in the soil, in plant remains and even in tools. In addition, the mosaic also affects plant seeds, retaining its activity for 2-3 years. But even after the expiration of this time, a certain level of infection still remains.

Methods of treatment of cucumber mosaic

First of all, it is urgent to separate diseased plants from the rest to prevent further spread of the infection. Remove the affected leaves and treat the cucumbers with Aktelikt or Aktara.

The tools used to care for diseased plants must be thoroughly disinfected in a solution of potassium permanganate.

The slowing down effect on the development of the disease is also provided by folk remedies, such as spraying:

  • low-fat milk (10%);
  • milk-iodine solution (10% milk and,% iodine);
  • tincture of dandelion;
  • decoction of onion husk;
  • tincture of tobacco;
  • weak garlic infusion.
