Kila cabbage is an insidious disease caused by a fungus. Cabbage is a very common vegetable crop. Plantations can be found in almost every garden plot. This vegetable is useful and appetizing, but it is not easy to grow it. It is quite difficult even for an experienced gardener to protect cabbage from keel and pest attacks, to follow the rules of cultivation. It is almost impossible to get rid of this disease.

What is a qila

Kile is susceptible to all varieties of cabbage and cabbage crops: turnips, radishes, lettuce. Its fungal nature makes the treatment of the plant impossible.The part of the infected plant above the ground looks depressed: the leaves become lethargic and begin to curl. This happens even if the soil is well hydrated.

If there is a keel, you need to pay attention to the root. If the disease has formed, then it will be possible to see a rhizome completely strewn with growths, which turns into branches that look unpleasant, even ugly. The true roots die fairly quickly and the plant ceases to exist.

But that's not the worst. Since keel is a fungal disease, its spores, multiplying, quickly fill the entire area, affecting other crops. Under the threat of destruction is everything that the gardener grows in the garden. Therefore, the sooner protection is organized, the more soil will be saved.

Besides cabbage, other crops can get sick:

  • radish;
  • rutabaga;
  • mustard;
  • watercress;
  • daikon.

If keel appeared on cabbage, then not all gardeners know how to fight. Early symptoms are difficult to detect.

When a plant begins to show the morbidity of its condition, it is already impossible to restore its strength and he alth, but you can save everything that is nearby. To do this, you need to know how to deal with keel on cabbage.

How the disease manifests

Before you get rid of infected plants, you need to get an accurate confidence in the reliability of the symptoms. The first sign by which the quila can be determined is withering leaves. With full confidence that this phenomenon was not discovered due to the dryness of the soil, it is necessary to dig out a future head of cabbage and carefully examine the roots of the plant. If they have convex sores, then this is a cabbage keel, which can affect the roots of other plants.

The symptoms that have formed on the roots literally jam the plant. Small roots, due to which the vegetable is fed, lose their ability to grow. The development of cabbage stops. Soon the development of growths becomes so active that the head of cabbage dies.

All plants diagnosed with cabbage disease should not only be removed, but also destroyed. Freeing the land is not difficult: the roots of the plant die off, the connection with the soil is lost, the cabbage breaks out easily.

It should be noted that the growths on the roots of a cabbage head can reach the size of a fist, and then begin to rot. Thus, a cyst forms in the ground, which spreads and infects he althy plants.

If the disease is not prevented, fungal spores may reappear within five years.

The defeat of a cabbage head with clubroot can occur at almost any stage of its development. Young seedlings are more susceptible to disease, their growth is active and fast. The increased acidity of the soil can affect the acceleration of the development of the disease.

Outwardly, the keel on cabbage manifests itself as wilting leaves. Slow development indicates a problem with the plant. At first, cabbage leaves have a light purple hue, which changes to yellow over time. If you do not take measures to save the crop, then after a short period of time all the plants will dry out, and the spores will continue to spread underground.

Spores, which are dormant in winter, tolerate cold very well. As soon as the weather conditions become favorable, they begin to grow. Zoospores are formed, which enter the plant through the root hairs. Producing growth to an impressive size, the bumps block the development of the plant, which is why the qualitative supply of moisture stops, and prevents the receipt of nutrients.

Cause of keel infection

The risk of clubroot in the garden occurs most often when cabbage seedlings are bought in unverified places.Working for profit, unscrupulous sellers save money on tillage and seedlings. As a result, you can easily bring the quila into your garden, and getting rid of it will be very problematic, especially if you do not know what to do in this case.

Spores of the fungus Plasmodiophora brassicae live in the ground for at least 5 years. This is a parasite that at first skillfully disguises itself. So, in the early stage of development, the sores are very small, and with the naked eye it is difficult to distinguish them from real roots.

In the process of growth, the growth increases in size, begins to replace the roots of the plant. In a ripe state, spores are also dangerous because they remain in the ground for a long time. Any plant that belongs to the cruciferous family can provoke the growth of fungal spores, even if it is a simple weed.

Methods of struggle

Ways to deal with clubroot on cabbage roots will be ineffective in the later stages of the disease. In this case, you can try only one method: to promote the development of adventitious roots. To do this, the head of cabbage must be highly spudded and systematically watered.

Before digging up the ground in late autumn, you can dust the soil with lime. However, the most effective way to avoid re-infection with clubroot is to avoid planting cruciferous plants in this area of the garden.

Of course, damaged parts of cabbage roots should not be stored on the site. It's best to burn them. Since it is almost impossible to cure an infected plant, certain actions can be taken to make the soil safe for planting that will appear on the site next year.

Seed treatment

Before you place the seeds in the ground, they must be processed, knowing how to treat. There are several ways to do this:

  • placement in an immunostimulator;
  • hot water treatment for 20 minutes;
  • exposure for 6 hours in a solution of mustard, the concentration of which is 1.5%;
  • placed in a solution of ascorbic acid, it takes 16 hours to process the seeds;
  • cooling during the day, the ideal place for this manipulation is a refrigerator, the temperature in which is not higher than 2 oC.

This method, of course, is not a panacea, because the disease of kila cabbage can get to the garden plot with seedlings. But if the infection is hiding in cabbage seeds, it can be eliminated using the above planting treatment methods.

Soil treatment

If the site was once affected by clubroot, the soil must be cured. First of all, it is recommended to grow in this area plants that kill quila spores on cabbage: tomatoes, potatoes, onions and garlic, beets. These crops can handle them in 2-3 years.

In one season, fungus spores can destroy plant combinations such as tomatoes and spring garlic.There are crops that, on the contrary, should be avoided in case of danger of defeat: you need to pay attention to the weeds that have appeared. Not bad can stop the development of the disease narrow beds: this technology helps to prevent the primary lesion when growing cabbage.

Recommended to pay attention to the possibility of mixing clean and contaminated land. This must be prevented. Prevention will reduce the spread of the disease so that the cured land will produce a good harvest.

Agrotechnical methods

Variants for dealing with clubroot on cabbage can be different, but one cannot do without the use of agricultural techniques. It is imperative to monitor the replenishment of the deficiency of the potassium and calcium components in the soil, to prevent a lack of zinc, chlorine, boron. The humus content can be increased up to 2.5 times compared to normal. S altpeter will not harm plants.

Kila is very crafty. When dealing with it, watering issues should not be ignored. It must be carried out very competently: waterlogging the soil can adversely affect it, as well as overdrying.

Folk methods

The truly effective control measures for killing cabbage are those that combine different measures. Do not ignore folk remedies.

Experienced gardeners call the most popular ways to process cabbage:

  • treatment with Bordeaux liquid - this tool effectively eliminates soil problems;
  • adding a small amount of wood ash to the hole - then water the plant;
  • watering with milk of lime;
  • regular loosening with the addition of mineral fertilizers.

If a keel appeared - a disease of cabbage, then few know how to fight, but simple folk tricks are familiar to everyone who seeks to obtain a plentiful and high-quality crop in their summer cottage. Everyone can act with folk remedies, because these are proven methods that do not require special financial costs.

How to prevent spread

The first thing that will help prevent the appearance and spread of clubroot is a careful inspection of the seedlings you buy. If it does not inspire confidence, it is better to refuse cabbage.

Prevention will help prevent the occurrence of this disease. These are the following measures:

  1. Mandatory hilling of the future head of cabbage after it has been fed, the plant needs to be watered. This contributes to the formation of a more powerful root system.
  2. Cleaning all stalk after harvest. Helps prevent possible growths from rotting.
  3. Pulling out all infected plants and burning them on a metal sheet. Do not walk around the garden at the moment in the usual shoes and clothes. The tool for the job must be separate, which is best destroyed later.
  4. Keeping soil acidity at an average level. The earth should not be too acidic or, conversely, under-oxidized.
  5. Feeding plants with potassium, calcium, magnesium, chlorine.
  6. Adding dolomite flour to the hole at the time of transplantation.

It would be useful to alternate crops planted in the same area. Varieties that appear in the beds must contain a mark on the packaging for resistance to the development of this disease.
