Saffron is a spice derived from the dried stigmata of the flowers of saffron crocus (Crocus sativus L.). In late winter and early spring of 2014, a disease of saffron plants was observed in two locations in the provinces of Albacete and Toledo in the region of Castilla-La Mancha (Spain).

Infected leaf sheaths were reddish to dark brown in color, and corms were rotten with a shredded appearance.
