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.
