The first report of Erysiphae cichoracearum var. cichoracearum on St. John's worth in Serbia
Prvi nalaz erysiphae cichoracearum var. cichoracearum na kantarionu u Srbiji
Abstract
In May and June 2006 severe incidence of powdery mildew symptoms in a plantation of St. John's-wort (Hypericum perforatum L.) that has been cultivated as a medicinal plant at experimental fields of Institute for Medicnal Plant Researchin (Pančevo, Serbia) was observed. In September of the same year numerous clestothecia of the pathogen were formed on spontaneous plants of St. John's-wort at Vlasina Mounti (locality Vlasina Lake). White mycelial petchs (approximately 5 mm in diameter) were observed on leaves, leaves petals and stems. At the end of summer mycelia covered leaves completely which and necroted and fall down before the end of vegetation, so such diseased plants were completely unusefull as herb drug. According to morphological features the fungus was determinated as Erysiphe cichoracearum var. cichoracearum. Powdery mildew pathogens have not previously been reported on St. John's-wort in Serbia.
Tokom maja i juna 2006. godine primećena je jaka pojava pepelnice na kantarionu (Hypericum perforatum L.) koji se plantažno gajio na komercijalnim zasadima Instituta za proučavanje lekovitog bilja u Pančevu. Tokom semptebra iste godine zapažene su brojne kleistotecije teleomorfa patogena na spontanim biljkama kantariona na Vlasini (Vlasinsko jezero). Bela micelijska navlaka javlja se na listovima, lisnim drškama i stablu. Krajem leta micelija prekriva celu površinu lišća, koje nekrotira, suši se i otpada, tako da su obolele biljke kantariona potpuno neupotrtebljive kao biljna droga. Na osnovu morfologije patogena gljiva je determinisana kao Erysiphe cichoracearum var. cichoracearum. Prouzrokovači pepelnice na kantarionu do sada nisu bili opisani u Srbiji.
