Blossom End-Rot

A small water-soaked or light brown area appears around the blossom-end or the side of the fruit, when the fruit is green or ripening.  The lesion enlarges rapidly, becoming straw-coloured and often papery.  Secondary fungi may colonize the damaged tissue as the lesion also provides an entrance for soft rot organisms.

Blossom-end rot is associated with fluctuations in the plant's water supply and heavy fruit load.  It can be more severe under high nitrogen rates and fast growth.

Blossom-end rot lesions may look similar to sunscald lesions.  Note the location and whether the site of the lesion has sun exposure.
