Blossom End Rot

Blossom End Rot

Blossom-end rot is a nonparasitic disease of tomato, pepper and watermelon. Losses can vary from a slight to more than 50 percent.

Symptoms

The first symptom is a slight water-soaked area on or near the blossom end of the fruit. The affected area soon darkens and enlarges in a constantly widening circle until the fruit begins to ripen. The tissues are dark and shrunken and have a dry, leathery appearance. With pepper the rot is tan in color and should not be confused with sunscald, which is white. The affected area may be merely a speck or it may involve half or more of the fruit (see illustration on tomato). Secondary microorganisms may grow on the decayed area.

Cause

Blossom end rot is caused by a lack of calcium in the developing fruit. This could be caused by a lack of calcium or by extreme fluctuations in water supply. Blossom-end rot is also increased where there is a low ratio of calcium to certain other nutrients such as potassium and nitrogen.
