Blossom-End Rot in Tomatoes: Causes and Prevention

Tomato growers must take care to avoid blossom-end rot (BER), a disorder that can dramatically reduce fruit quality and quantity. By using a few simple irrigation and fertilization practices, damage from BER can be prevented or reduced. Blossom-end rot is a physiological disorder or an abiotic disease (caused by drought, freezing, and other stressors). It is not a disease caused by fungi, bacteria, or other pathogens. Blossom-end rot is easily identified as a brown, leathery rot developing on or near the blossom end of the tomato. It starts with a dry, brown lesion the size of a dime and generally increases in diameter as the condition worsens. In time, lesions often become covered with a secondary black mold. There is also a condition called internal blossom-end rot in which symptoms develop on the sides of the fruit or internally. You might not see the damage until you cut into the fruit.
