Gray rot. It is affected by cabbage usually when stored, a white fungus appears on the leaves. As with white rot, it is necessary to observe the correct crop rotation, to carry out the warehouse disinfection and establish the recommended temperature regime. During the period of feeding, use nitrogen fertilizers in small quantities, to remove the yield of cabbage to storage before the onset of frosts.

Kila is the most dangerous cabbage disease. It occurs when the soil is excessive during the cultivation of seedlings. The fungus is striking the roots of the plant, which makes recovery almost impossible. At the very beginning of growth, the disease is difficult to detect, cabbage fade, dries.
