First report of fire blight caused by Erwinia amylovora on meadowsweet (Spirea prunifolia) in Turkey.
During the springs and summers of 2008 and 2010, dying branches, necrotic leaves attached to shoots, and blighted twigs of meadowsweet (Spirea prunifolia [Spiraea prunifolia]) were observed at three different locations of landscape areas in Konya Province, Turkey. Disease incidence was approximately 1% on the plants during the surveys. Initial symptoms of reddish to brownish streaks on the shoots of infected plants were observed in spring. Nine representative bacterial strains were isolated from the lesions on shoots of seven meadowsweet plants on nutrient sucrose agar medium and identified as E. amylovora based on biochemical, physiological, molecular and pathogenicity tests. This is thought to be the first report of the occurrence of fire blight on meadowsweet in Turkey.
