Top rot is a fairly common disease. It can be wet or dry. The first type of rot is also called bacterial. The diseased plant is covered with wet spots of various shapes. Superficial or dry affects even unripe tomatoes. It appears as small, dry, dark spots.

• strong acidity of the soil;
• hot and dry climate;
• excessive amount of nitrogen in the soil;
• damage to the root system.

You can notice that the plants are sick by regularly examining your site. The following signs indicate that tomatoes are affected by apical rot:
