Kila on the cabbage is a nuisance that can destroy the future crop literally in the bud.
Let's first understand what kind of keel is this and how dangerous it is. The keel occurs due to an infection that infects the roots of the plant. The causative agent of the disease is a fungus that is dangerous for the cruciferous root system. Cabbage, the keel on which hit the roots, will die. It is especially fatal for seedlings.
This disease is most susceptible to white and cauliflower. Kila for these species is most dangerous. When a fungus is infected with young plants, the disease manifests itself in about a month. Therefore, when planting seedlings in a permanent place, there is a risk of simply not noticing such a nuisance.
The cabbage, on which the keel has nevertheless formed, stops in growth, begins to wither. This is due to the fact that swelling or growths form on the roots that prevent the plants from getting the necessary nutrients through the soil.
Cabbage, on which the keel was formed in the early stages, as a rule, does not form a head, and if an older plant is affected, the head is very loose.
The growths quickly enough increase in size, then rot and release into the earth a large number of spores of the fungus that causes the disease. So there is a contamination of the soil. Further spores can spread throughout the site using insects and groundwater.
If your cabbage looks sluggish with sufficiently moist soil, this is one of the first signs of the disease.
Of course, the question further arises: "What to do, how to get rid of the keel of cabbage?"
In the event of the first signs of the disease, care must be taken to reduce the source of infection. In such cases, the plants are removed and burned, and the place where the cabbage grew is treated with potassium permanganate, dissolving it in water to a dark pink color.
Unfortunately, at the place where the disease manifested, you can not
plant cabbage for about 5 years. That is how many spores of the harmful fungus survive. During this period, it is recommended to sprinkle the soil with plenty of lime.
Currently, it is impossible to save the plants affected by the fungus. How to save the future crop, saving your plot from such a nuisance as keel on cabbage? How to deal with this disease?
As the saying goes, the disease is easier to prevent than to cure. Therefore, the timely implementation of preventive measures will reduce the risk of the disease to a minimum.
Plant cabbage seedlings every year in a new place. Waterlogged soils must be drained. Try to avoid using fresh manure or compost on future beds of cabbage. Buy seeds of plants that are resistant to the disease. Having bought seedlings in the market, carefully inspect each seedling. Of course, carry out procedures that reduce the acidity of the soil. To do this, use lime. Immediately before transplanting seedlings into the soil, the wells are poured with milk of lime.
Following these simple recommendations, you can protect your crop from infection and save it.
