Diseases of cabbage and methods of dealing with them


This fungal disease is quite common, it develops in the cells of the root system of the plant. Most disease affects early cabbage, cauliflower and white cabbage, regardless of the place of cultivation. At the seedling stage, various growths are formed on the roots of the seedlings, which disrupt the nutrition of the culture. Due to this, the plant lags behind in development so that even the ovary does not occur.

At the end of the growing season, the growths of the root system of cabbage rot, decompose and enter the soil, which is seriously infected.

How to deal with the disease

The fight with keel is quite simple, the main thing is to pay attention to its signs in time. Plants that have died or simply wilted from the disease should be removed from the bed with a lump of soil, and the place of the plant should be well sprinkled with lime.

The reason for the black leg of cabbage is high humidity and poor ventilation. This is a fungal disease that affects the root neck and base of the stem. These parts of the plant become very thin, blacken and begin to rot, due to which the plant lags in growth and most often dies.

Cabbage with a black-foot disease can not be planted in the ground, since seedlings will not give any result.

This disease seriously affects young plants. Leaves acquire gray and yellow spots with a coating on the underside. If the defeat of the seedlings is serious, then the leaves die off over time, cabbage lags behind in development, and sometimes it simply dies.

The disease can seriously affect the quality of the crop, it is most often manifested due to excessive moisture.
