In greenhouses and in the garden, many infections can occur, which appear on plants from the soil, are transmitted from nearby crops or by another method. There are those that can instantly ruin the harvest, so you need not only to know the peculiarities of cabbage cultivation and apply a lot of effort to get the result, but also to look closely at the change in the appearance of seedlings or heads of cabbage, because some of them can have serious pathologies.
Diseases of cauliflower, white cabbage will be discussed below. We will also note the most productive ways to deal with them, which have been used by specialists for a long time.
Diseases and remedies
Like any garden crop, cabbage often encounters disease.
pounds
This fungal disease is considered very popular, it progresses in the cells of the root system. The disease itself attacks young cabbage, cauliflower and white, regardless of the place of cultivation.
At the time of seedling, various growths appear on the roots of the seedlings, disrupting the nutrition of the vegetable. Because of this, the plant no longer develops, even the ovaries are not formed.
How to eliminate?
It is very simple to eliminate the keel, it is important to notice the symptoms of the disease in time. Plants that have died out or dried up from a disease must be removed from the garden along with the ground, and the plant site must be thoroughly fertilized with lime.
You should not sow diseased seedlings into the ground, you also need to add lime to the soil at the time of planting. Diseased soil is available for cultivation of other crops, since cabbage disease affects only crucifers.
Blackleg
Black leg disease occurs with high humidity and insufficient ventilation. It is a fungus that attacks the collar and stem of the stem. Such parts of the plant thin, turn black and rot, because of this, the plant lags behind in formation and most often dies off.
How to eliminate?
To get rid of this cabbage disease, you need to start with precautions. In our situation, this is the elimination of soil for planting cabbage, infected with black leg. If the crop has died out in the garden due to this disease, then the soil must be replaced or the cabbage must be planted in another place.
Moreover, the prevention of blackleg consists in the permissible humidity and regular ventilation of the greenhouse where the cabbage grows. Before sowing seeds, they must be treated with Granosan. It is necessary to add a special agent to the soil before planting seeds.
Mildew
This disease seriously attacks early shoots. The leaves become grayish, with yellow spots with a bloom on the lower part. If the damage to the seeds is serious, then the leaves die out over time, the cabbage stops forming, sometimes it dies.
How to eliminate?
To preserve the leaves, you need to stabilize the moisture and also treat the plants. It is necessary to spray the cabbage with wrestling solution. If you are processing at the time of seedling, then the level of funds should be half as much, and the consumption should be no more than 1 liter per frame.
It is imperative to research the crop during cultivation, from sowing to mature plants, as insect diseases can prevent you from enjoying tasty fruits at the end of the season.
Fuzarioz
These are very popular fungal infections of the vegetable, and the fight against them is not difficult with timely detection and therapy. Fusarium is considered such a disease. Fusarium mushroom is considered the pathogen of fungal wilting. The disease affects all types of cruciferous plants. The fungus, penetrating into the vascular component of the plant, blocks it, provoking wilting.
Among summer residents, such a disease is called jaundice because of the characteristic signs: yellow blotches form between the vessels, gradually the whole plant turns yellow and dries up. At the end of the stem of the leaves, you can see brown spots – a fungus.
With such a lesion, it is necessary to eliminate diseased plants and treat the crops with benzimidazole fungicides. The fungus can live in the ground for a couple of years, so you need to follow the rules of agricultural technology – do not plant in one place for several seasons in a row, and also remove organic residues from the ground.
Viral diseases
Viral diseases are observed less often, but multiply rapidly, it is unrealistic to eliminate them, they are the result of the loss of the entire crop. The mosaic virus is often found among summer residents; it has a huge number of species, many of which are still unclear.
It is dangerous not only for cabbage. It is transmitted with unwashed tools and infected pests into the stem tissue and liquid of other plants, mutates and multiplies further.
Methods for protecting cabbage from viruses
The mosaic is of a viral nature and cannot be treated with insecticides. That is why attention must be paid to prevention: disinfect seeds before sowing, promptly eliminate diseased plants along with the soil, eliminate weeds that can carry the virus, and eliminate parasites. Mosaic can get sick by mechanical injury and sucking insects, so you need to productively fight insects that carry this virus.
vermin
Parasites bring great harm to the crop. They love to feast on young shoots, attack the seedlings in spring, while they not only injure the plants, but also transmit the virus and fungus. In order for cabbage to give a high-quality harvest, pest control and systematic preventive measures are simply needed.
Cabbage aphids
If you do not carry out systematic processing of cabbage, then pests will certainly appear, and it will be harder to eliminate them than to take preventive measures against their appearance. One of these pests is aphid that eats the sap of the plant. Small insects are small and silvery in color.
Located at the bottom of the leaf, they absorb the plant. Even in spring, when sowing the first seeds, aphids settle in groups on young cabbage. It is possible to identify the presence of a pest by external signs: the formation of plants is dulled. the leaves lose their original color, a pink tint is formed, the leaves wrap and die off.
To eliminate aphids, you need to use insecticides. You can scare off pests with harsh tobacco smoke, garlic, or onions. Aphids do not like the neighborhood with carrots and tomatoes.
It is imperative to research cabbage during cultivation, starting with seedlings and ending with adult plants, because diseases and pests can simply kill the crop, you must know all the features.
