CROCUS DISEASE PROBLEMS
Scab causes pale yellow, water-soaked lesions on the
corms. The lesions turn brown or nearly black and are
sunken with raised brittle margins. A gummy exudate may
be seen. Discard diseased corms and plant healthy corms
in a new area.
Dry Rot causes lesions on the corms and leaf sheath decay.
Use a new planting area each year.
Corm rot symptoms are water soaked spots.
