As a result, the root neck softens significantly, darkens, as a result, a constriction forms. As a result, the plant withers and dies. Often such a disease develops in greenhouses that are not ventilated. If infected seedlings are planted in the ground, it will quickly die. To combat this disease, you need to engage in seed dressing, disinfect greenhouses, properly care for seedlings in them.
- Alternariosis . Hot weather with periodic rains can contribute to its development. The disease usually affects tomatoes, but also pepper. As a result, the leaves of the lower and upper tiers are covered with dark brown rounded spots, then they gradually die. The fruits suffer from black spots in places of cracking and near the stalk. The same goes for the stems. The disease can affect seedlings, adult plants. To avoid this, it is important to strictly adhere to the crop rotation, that is, return the pepper to its previous place no earlier than three years later. During the growing season, plants must be treated with special chemicals.
- Septoria Striking in open and closed ground Bulgarian pepper. The disease is often found in fairly humid areas. Dirty white spots with a dark border appear on the leaves. In case of severe damage, they cover the entire surface. Leaves turn yellow first and then dry. Due to this disease, yield decreases on average by 40 percent. You need to deal with it in the same way as with the previous one described above.

- Lightning fast bacterial wilt . In this case, bell pepper retains its normal color. Such diseases are precisely why they are dangerous. The plant simply withers, and white mucus flows from the stems with an incision. To prevent infection, crop rotation must be observed and nightshade crops should not be returned to their previous places after 3 years.
