seedling diseases in greenhouse

Before making prevention of soil and seedling process should become familiar with what to struggle and why there are such problems.

Among the most common diseases, it can be noted a number of some particularly vividly manifest :

  1. The leaves are white.
  2. There is southern late blight and fly.
  3. Yellow leaves of the seedling.
  4. Root rot has begun.

To prevent sprouting, it should be grown in quality soil at the optimum temperature To seedlings did not hurt, it should be grown in soil quality at the optimum temperature for it

most common fight is such a problem as blackleg. Each type of disease has its own characteristics and requires a unique approach, and it should be done so that the infected seedlings do not die. White spot on the leaves is a consequence of the development of fungal disease, the causative agent of which persists in the rhizome of the diseased plant and can cause contamination of the soil.

It is because disease control fungal lead as carefully as possible, in particular in order to avoid the spread of disease, it is necessary not only to process, but also to remove the diseased leaves, and completely out of the greenhouse, because they can penetrate into the ground in the form of weeds and to continue the spread of a fungus.

Treat soil and plants to get rid of a problem like a fungus can be manganese potassium. The peculiarity of southern late blight lies in the defeat of the roots of seedlings, which literally destroys both the root part and the radical root, including later it will extend to fruits of tomatoes, peppers and cucumbers. The source of the disease is a soil that has already been infected. To exclude the spread of infection, it is necessary to carefully remove the remains of plants from the soil for the winter. The diseased vegetable cultures are removed, and everything else is digested. To cure the plants, during the period of exacerbation, it is not necessary to carry out foliar top dressing and to avoid overmoistening of the soil for more than 70%.

If the foliage has become covered with yellow specks or has simply begun to fade, this becomes the result of the formation of a soil fungus. To test the plants for this problem, you need to cut the roots across and if there is a ring of brown vessels, then there is a fungus and you need to fight it immediately. To protect seedlings, it is necessary to clean the greenhouse of plant remains in the fall, and also to carry out soil disinfection. Plants that are affected should be removed as far as possible, and the place where they grew soaked with fungicides.

Root rot is most often found in primulas. The disease manifests itself in the form of blackening and thinning of the stalk, and the plant begins to rot. The plant is infected through the root system, and the main source of infection is the root of the old diseased plant. In extremely rare cases, the disease can be introduced to the seeds, and in order to avoid such a moment, they must be heat treated before planting, and the ground for seedlings is roasted in the oven.

The yellowed leaves in the greenhouse

Seedlings allow: to prepare a stronger basis for the future crop, to eliminate weak shoots in advance, to achieve a better harvest. However, in order to obtain what is required, it will be necessary to carry out a number of preliminary works on processing and care, especially if the problem begins such as yellowing of the foliage. To understand why the seedling turns yellow is not easy, because there is an incredible number of reasons.

If the leaves turn yellow in the greenhouse, then perhaps the plant does not have enough nutrients in the soil If the yellowed leaves in the greenhouse, it is possible that the plant is not enough in the ground

nutrients

At first glance it may seem that in a certain case all the reasons are collected, but it is not. First of all, the color of foliage changes due to malnutrition.

To be more precise, the color can change with a lack of power and with its overabundance. If the foliage hardens and thickens, then this is a clear sign of a lack of sulfur. If there is too much lime, then the color will be light yellow, both on the young and old foliage, which gradually all dry up.

Also, the foliage can turn yellow if the watering is too frequent. In any case, the problem lies in the wrong care of the culture, and do not immediately resort to serious fungicides that eliminate the infection, as they can simply ruin the harvest that has not yet started appearing. To ensure that the seedlings are properly nourished, you need to carry out proper feeding during the period of growing the foliage.

For this you can use :

  • Mullein solution with ash;
  • Combination of slurry and ash.

If a vegetable is infected with a disease, strict adherence to treatment and preventive measures is required.

How to treat the soil in the greenhouse against diseases

The soil can be affected by moles, moss and even sometimes blooms, resulting in a white coating.

However, all this can be avoided if :

Many gardeners begin to literally panic when the ground begins to turn green. Naturally, many questions immediately begin to arise, such as whether it is dangerous, whether the probability of eliminating the problem is great, and how to cure it. Eliminate the moss even before its appearance.

For this purpose it is necessary to carry out decontamination of the soil, and also to become acquainted with the reasons for the formation of the greens:

  1. Too much fertilizer in the soil.
  2. High soil moisture.
  3. Minimum ventilation in the room.

First of all, in the case of landscaping, the irrigation needs to be reduced, and if the moss begins to spread actively, then it is necessary to completely stop watering before the soil completely dries.

Black leg in the greenhouse

The black leg is a fungal disease, the causative agent of which lies deep in the soil and, together with it, gets into cups and boxes with seedlings.

Disease may result from :

  • Elevated soil moisture;
  • High air temperature in the room;
  • Elevated soil temperature.

If you find a plant that has a black leg, it should be immediately discarded from the greenhouse.

If a particular problem is found in a particular shoot, then remove it with the root. As soon as a black leg began to appear in the greenhouse, immediate disinfection of the land by means of a special composition is necessary. To reduce the likelihood of death of plants from the black leg, you need to make a mixture of soil when replanting the cups of wood ash.

It is quite possible to avoid the black leg altogether and for this you need to carefully monitor the soil condition so that there is no overheating and waterlogging.

To exclude dampness, after watering, sand should be poured in dry form under each plant. The danger of the black leg is that it can kill a wide variety of seedlings and, not only cabbage, which is very fond of moist soil, but other types of crops, such as tomatoes, cucumbers and peppers.
