What to do when cabbage rots on the vine

White cabbage is considered unpretentious to care for, but sometimes difficulties arise when growing it. Rot on the leaves or inside vegetables is a common problem that jeopardizes the entire crop. Let's figure out why cabbage heads rot in the garden and what to do if it was not possible to prevent rotting.

What to do if cabbage rots on the vine

Head rotting occurs for such reasons:

• non-compliance with the rules for caring for the plant;
• unfavorable climatic conditions;
• diseases and pests.

Improper agricultural practices stimulate the development of root rot.

When planting cabbage on the site, it is important to consider the following:

1. Observe the planting pattern, keeping 70–80 cm between heads of cabbage, and 90 cm between rows. Heads of cabbage that have formed in this way will not shade each other and interfere with the development of neighbors.
2. Plant in a well-lit area, away from trees, shrubs, fences and buildings.
3. Avoid the formation of dry crust on the ground. Loosen the soil after each watering or heavy rainfall so that the roots receive enough oxygen and moisture does not stagnate.
4. Do not plant cabbage in the same place from year to year (take a break for at least 4 years) or after plantswith which she has common diseases (radish, radish).
5. Use nitrogenous fertilizers only when landing... During the period development of heads cabbage needs potash feeding.
6. Plant plants in soil with neutral or close acidity values ​​(pH 6.2-7.5).
7. Before planting seeds for seedlings disinfect them: for example, soak in a weak solution of potassium permanganate.
8. Provide plants with drip irrigation without flooding the outlet.

Note! Most often, it is the violation of agricultural technology that causes cabbage rot.

When choosing varieties for planting it is desirable to select adapted for growing in a specific region. If the summer turned out to be rainy, and the soil does not have time to dry out after precipitation, a canopy of film is made over the beds and leaves in contact with the ground are removed. Due to the high humidity, rot quickly forms on them, which spreads throughout the plant.

Heat also contributes indirectly to rotting.... Together with high humidity, it creates favorable conditions for the reproduction of pests that damage plants and carry pathogens.

It is important to carry out pest prevention on timeusing drugs like "Fitosporin", "Knockdown", "Iskra-M" or folk methods:

• 1 tbsp. pour the peels of garlic and onion with a bucket of boiling water and leave for 24 hours, strain and use for spraying once a week;
• 1 tbsp. l. Dissolve 9% vinegar in a bucket of water, apply once a week, spraying the solution over the plants;
• Powder the cabbage with wood ash once every 2 weeks.

Gardeners advise planting plants with an insect repellent smell next to cabbage.: marigolds, garlic, oregano.

Blackleg

A common crop disease that destroys hopes for a good harvest, - black leg.

When cabbage is affected by a black leg, the symptoms are visible immediately: lower stem darkens and rots. The disease occurs at all stages of cultural development. Of the main reasons, there is an excess of nitrogenous fertilizers, a lack of oxygen and excessive watering.

Attention! Sharp temperature changes can also provoke the development of a black leg.Therefore, it is important to transfer the seedlings to open ground after spring frosts, and when growing in a greenhouse, monitor the temperature regime and avoid sudden jumps down.

There are several varieties of white cabbage that are resistant to this disease.: Moscow late 9, Belarusian 455, Amager 611. The preparations "Fitosporin", "Planriz", "Baktofit" help to fight the black leg.

White rot

Due to prolonged rains, when the weather is wet and the heads of cabbage do not have time to dry out, cabbage is susceptible to this fungal disease.... White mucus appears on the upper leaves, and mycelium develops in the voids between them, gradually approaching the core of the vegetable.

Sometimes the disease develops from below, penetrating the head of cabbage from the soil along the stem, especially if the size of the plot does not allow changing the location of the cabbage from year to year. Therefore, before placing seedlings in open ground, the soil is abundantly watered with boiling water to destroy the spores of the fungus.

Peronosporosis

The causative agent of downy mildew is waiting in the wings in seeds and seedlings, it is activated later, when the heads of cabbage begin to grow actively... Of the first signs, yellow spots of irregular shape are noted on the upper leaves. They spread, gradually the leaf dries up and dies off. After that, a white powdery coating forms on the cabbage, under which the plant darkens and begins to rot.

To prevent peronosporosis, gardeners disinfect seeds before planting. and observe the scheme for placing plants in the garden. Cabbage is planted in decontaminated and decontaminated soil.

Vascular bacteriosis

Develops in regions with warm and humid climates... It is manifested by darkened vascular veins and black spots on the stem. Because of this, the plant does not receive nutrients from the soil and slows down growth. In case of vascular bacteriosis, heads of cabbage are not tied.

Prevention of the disease is a thorough cleaning of the beds after previous plants and protecting cabbage from heavy rainfall (for example, by creating a film canopy).

Why does cabbage rot from the stalk

Dangerous enemy of culture - slimy bacteriosis, or wet rot... The disease has 2 variants of its course, one of which is the penetration of bacteria through lesions on the upper leaves. In this case, microorganisms get to the stump and soften it, which causes the head to fall off.

Several factors provoke the development of wet rot:

• when leaving, the heads of cabbage were damaged;
• the soil is swampy or oversaturated with moisture due to heavy rainfall;
• due to frequent rains, the leaves and head of the cabbage are constantly wet;
• the plantings are attacked by caterpillars eating the upper leaves.

Often slimy bacteriosis affects the plant at the second stage of vegetation.

What to do if the cabbage head rots in the garden

Having noticed traces of decaying cabbage, gardeners do not always know how to save the crop. The algorithm of actions depends on where exactly rot is manifested.

In the middle

In this case, it is impossible to save the affected heads of cabbage, the rot will continue to spread... Therefore, they are dug up and burned outside the site, and healthy plants and soil are disinfected. The soil is watered with a 3% solution of copper sulfate. Consumption of funds - 2 l / m². The drug "Previkur" is also suitable.

Attention! Healthy cabbage is sprayed with Fitosporin.

With mucous bacteriosis, diseased plants are dug up and destroyed, carefully removing plant residues from the beds. The soil is disinfected with a 0.5% solution of potassium permanganate or 3% - copper sulfate.

Upper leaves

If putrefactive lesions are seen on the upper leaves, the plants can still be saved... To do this, the diseased cabbage is cut off, the covering leaves are removed, and the heads of cabbage are allowed to go for culinary processing.

If the crop is not yet ripe, diseased plants are left by cutting off the affected leaves. almost at the base. It is important to remove all rotting surfaces. After that, the cabbage is treated with Fitosporin, and the soil beneath it is treated with Previkur.

Conclusion

Cabbage is unpretentious in care and, subject to agrotechnical practices, gives a rich harvest. However, if you neglect them (choose varieties that are not adapted for the region, do not fight the first manifestations of diseases or pests), the heads of cabbage begin to rot.

Take regular preventive maintenance measures, follow planting rules, and select varieties that are resistant to disease. Then in the fall it will be possible to harvest a good harvest, which will last until spring.
