First report of Stromatinia gladioli causing neck and corm rot of Crocus sativus in Spain.

Abstract

In late winter and early spring of 2014, a disease of saffron(Crocus sativus) plants was observed in two locations in the provinces of Albacete and Toledo in the region of Castilla-La Mancha, Spain. At each location, an area in size between 1,000 and 3,000 m2 was affected, with plants displaying symptoms of wilting and yellowing. Infected leaf sheaths were reddish to dark brown in color, and corms were rotten with a shredded appearance. The causal pathogen was isolated and identified as Stromatinia gladioli based on molecular data (sequence analysis of the ribosomal DNA internal transcribed spacer region) and pathogenicity analyses. This is thought to be the first report of S. gladioli causing neck and corm rot on saffron in Spain.
