Often, after harvesting cabbage, due to lack of free time, gardeners or for other reasons, the leaves and cobs remain on the site. Of course, until the next spring, most of the cabbage remains will rot, and the rest in any case will be removed before the start of the planting period. However, such waste can cause huge damage to the site in case the cabbage was affected by diseases. Disease spores can penetrate the soil and with the arrival of heat will begin to multiply actively, hitting the planted plants.
Some of the most common diseases of cabbage are:
- keel;
- mucous bacteriosis.
Cabbage Sternum
The second name of the disease is the root cancer. Affected plants externally practically do not differ from others, except that the leaves wilt slightly and turn yellow. However, when digging a stump out of the ground, the diagnosis can be made immediately: small thin roots are as if inflated due to the build-ups formed on them.
The cause of the disease is a fungus, which quickly develops in moist soil, while curing diseased plants is impossible. They must be removed and disposed of.
Kila is very easily transferred to other plants through the soil in which the fungi remain, so the land from the site on which the diseased crops grow should also be removed.
After the destruction of the sick cabbage, the beds should be treated with a solution of the Bordeaux liquid. Plant such crops there will be no earlier than 5 years.
For the prevention of cabbage disease, it is recommended to apply fertilizers with a predominance of calcium, ash and colloidal sulfur to the beds.
Mucous bacteriosis
The disease is also called wet bacterial decay. It first affects either cabbage leaves or a stump. In the first case there is a characteristic smell, the leaves are covered with a mucous coating and rot. Soon, bacteriosis spreads to the whole plant down to the poker. In the second case, the development of the disease begins with a stump.
Bacterial decay affects weakened plants not only of cabbage, but also of other crops, especially in the presence of damage and in conditions of prolonged rains. The maximum is manifested during storage of the crop in a room with a high temperature or during transportation.
When the first signs of rotting cabbage bushes appear, spray it with a solution of the Binoram preparation. For the prevention of the disease:
- Sift the wells with the same solution;
- seeds etch;
- Before planting seedlings, treat her roots with Phyto-Flavin.
In addition, it is necessary to maintain the temperature regime during the storage of the crop.
