The defeat of vegetables by such a dangerous disease as keela occurs in two ways: through seedlings and through the soil. How to prevent the appearance of a dangerous infection in your garden and what to do if it does appear?

Keela came from where they did not expect

Most often, keela comes to our plots with purchased infected seedlings. The trouble is that it is not always possible to see the infection in time. Symptoms become noticeable on the roots only after a month from the day of sowing. And since the planting of seedlings often occurs with a clod of earth, then the thickening with growths can not be seen. Then the aerial parts of plants will already talk about the presence of the disease. On cabbage, it looks like this:

• plants are stunted;

• leaves wilt and turn yellow;

• forks do not tie well, heads are loose.

To make sure that the disease is present, you need to dig up a couple of plants from the garden and examine the root system. If gray bumps were found on them, then the seedlings were unhealthy and now the infection can spread in the soil. When spherical growths or thickenings resembling icicles are formed on the lateral roots, this is evidence that the seedlings were healthy before moving to the beds and the soil was already infected before that.

Keela is dangerous in that it interferes with the development of plants and it is very difficult to clear the soil from it. In addition to cabbage, this disease affects all members of the cruciferous family. That is, if it was found in the garden, it is not recommended to grow cauliflower and Chinese cabbage, turnips and radishes, mustard and watercress on these beds for 4-5 years. The infection quickly spreads to neighboring beds.

She's not afraid of fire, or compost?

Keel fighting is not an easy job. Plants affected by it cannot be sent to compost, and they need to be burned in a special way. Where does keela come from on the site? It is spread by controversy. Then, having got into the compost with the affected plants, the infection does not rot and, together with fertilizers, enters the soil.

Sick seedlings need to be dug out together with a clod of earth. Do not shake it off in the beds, but take it away from the garden and dry it. Then arrange a bed of iron, douse with gasoline and burn. If the affected plant debris is not treated with combustible material, cabbage will smolder, and smoke and wind can spread the infection further.

Another method of disposing of such waste is to make a pit for it. When dumping infected vegetables, they need to be generously stratified with nitrogen fertilizers.

At the same time, it is advisable for the gardener to allocate overalls for such work: gloves, boots. The infection can be carried from place to place on the sole. After sanitary work, tools and shoes should be washed, and clothes should be washed.

Preventive measures

The gardener will save much more time if, before planting the seedlings, he carries out preventive measures for disinfection, than then begins a long struggle with the pathogen. After all, if it is found in the garden, planting in this cruciferous is not recommended for a long 5 years.

Purchased seedlings can be disinfected with fungicides that contain sulfur. This is a solution of copper oxychloride, colloidal sulfur. And the landing holes are recommended to be treated with a solution of lime or chalk, infusion of ash.

Lime milk has proven itself well. To prepare it, you will need 1 kg of lime per 10 liters of water. Liquid consumption per hole - 1, 5-2 cups. Keela develops more on acidic soils. Therefore, it is recommended to lime the site.

For the future, to grow your seedlings, you need to choose hybrids that are characterized by increased disease resistance. These include Kilaton F1, Kilaxi F1, Kilafur F1. Their names are easy to remember, they already contain a mention of the keel.
