tomato blossom-end rot Blossom-end rot of tomato, caused by unbalanced moisture and calcium deficiency.

Blossom-end rot is a physiological disease affecting fruits, most commonly tomatoes. It is characterized by sunken, leathery areas around the blossom end of the fruit, which may appear water-soaked or turn brown. This condition is primarily attributed to significant fluctuations in available moisture. While not caused by a pathogen, it is a type of rot, which is a symptom of plant disease involving tissue decomposition. Other types of rot can be caused by fungi and bacteria and affect various plant parts.123
