Zusammenfassung:In 2007, wilting and crown rot were observed on recently transplanted gloxinias (a popular ornamental houseplant) in a commercial greenhouse in North Carolina. The pathogen was identified as Phytophthora tropicalis based on morphology and sequencing of the ITS rDNA region. Pathogenicity of the isolates to gloxinia was confirmed by successful completion of Koch's postulates. To our knowledge, this is the first report of Phytophthora tropicalis on gloxinia. Accepted for publication 2 June 2010. Published 8 July 2010.
