At the forums of gardeners and gardeners, participants often send photos of their seedlings and complain that paprika have appeared on the leaves on the leaves. It’s not worth worrying about the fact that this disease will destroy all grown plants. This is the so-called oedema - a deviation from the norm of their development, but not as dangerous as most diseases.
Description and signs of the disease
The disease is often popularly called "dropsy", although in its essence it is not a disease at all. It manifests itself in the form of cork growths, small swollen tubercles from the underside of the leaf closer to the petiole, and sometimes on the petioles of plants. In the latter case, the disease looks like white mold. 
It covers the stem with dotted or solid spots, which sometimes causes the stem to curl.
Scalloping looks watery, but when groping, they appear rather dense, similar to warts. The color of the plant itself does not change, it remains natural.
You will be interested to learn more about growing peppers.It is believed that this problem is characteristic of plants living in the greenhouse, since it is difficult to regulate the necessary humidity conditions there. But if the disease occurred in home seedlings, in the greenhouse, it returns to normal.
Did you know? Odema translated from Latin means “edema,” that is, fluid accumulation in tissues, cavities, the intercellular space of the body.Pimples usually appear on one to three sheets. The pepper seedlings themselves continue to grow and look healthy, which is what distinguishes this deviation in the development of the plant from other leaf diseases.
Causes of
The reason for such deviations are not bacteria, infections or fungi. The problem is the lack of sufficient illumination and a strong waterlogging of the soil.
In such conditions, part of the roots of the plants die off, respectively, the nutrition of the ground part is disturbed. Hillocks appear exactly in those places that were supplied with nutrients of the dead root.
Therefore, the leaves of sweet pepper affected by edema will no longer recover. But if you restore the necessary conditions for the growth of seedlings, new ones will grow absolutely healthy.
Important! Most often the disease occurs in seedlings, which is under illumination, stands in a limited space tightly to each other.Since the cause of pimples is waterlogging, the problem may lie not only in excessive watering, but also in air temperature, its humidity.
The emergence of the disease contributes to unstable spring weather. For example, on a sunny day, the seedlings were well watered, and then a cold snap came, and the wet ground got very cold, the sun became less. These are ideal conditions for the appearance of oeda. Therefore, it is not surprising if, after such drops, over time, healthy lower leaves seem to disappear from seedlings.How to protect sweet peppers from edema: methods of control and prevention
There are no special means and methods to combat oedoma. It is enough to level the regularity and volume of irrigation, give the seedlings more light, loosen the ground after irrigation if it is too dense - and over time new formations will not arise.
Check out such varieties of sweet peppers as "Bogatyr", "Gypsy", "California miracle".It is also recommended to arrange the seedlings so that there is more space between the pots, so that they receive more light. Gently air the room.
As a preventive measure, it is recommended to use land with good drainage. It should be the fifth or fourth part of the pot.
Important! Pimples on the leaves can talk about the defeat of seedlings spider mite, shield, or aphids. In the last two cases, a sticky coating appears on the leaves, and in the first - a barely noticeable cobweb.
Should I treat oedemu
Oadema of the leaves of sweet pepper is characterized by the fact that the affected areas of the leaves are not restored, because their nutrition is not restored. We must take for granted that in time they will disappear. Although if the defeat is not critical, they may continue to grow further. 
There is no need to treat this disease. It is not contagious, does not affect the yield and stops when the necessary living conditions of the seedlings are restored. But if you really want to help the plant, you can remove the affected leaves, and bury the stem to the level of healthy leaves. Of course, if the pepper is still low. With the pimples on the adult seedlings should simply accept.
Did you know? Due to watering with cold water, the pepper also gets sick and quickly dies.Pepper pepper is not even a disease, although it is not a good sign of plant development. Clogging up the permeability of the nutrient channels of the leaf with an excess of moisture indicates abnormal conditions of plant maintenance. Therefore, it is enough to restore the proper moisture regime, increase the amount of light, arrange the seedlings more freely, so that the problem does not recur.
