Blossom End Rot (CCD-FS-11)

Blossom end rot is a physiological disorder common to many fruiting vegetable crops, especially tomatoes and peppers. Cucurbits, like cucumber, squash, and watermelon, can also be affected. Abiotic diseases are caused by non-living components, which in the case of blossom end rot, is a calcium deficiency in fruit resulting from any of several different production conditions.

This new fact sheet by Extension Horticulturist Rachel Rudolph (in conjunction with the UK Center for Crop Diversification) discusses blossom end rot symptoms, causes, and management.  It replaces the Plant Pathology fact sheet of the same name (PPFS-VG-02).

Blossom End Rot (CCD-FS-11) is available online.
