摘要：This paper reports on a two-year monitoring of Phytophthora species occurring in the
catchment area of the Rák Brook near Sopron. P. gonapodyides, P. lacustris, P. plurivora and
P. pseudosyringae were found in the course of surveys completed in the vegetation period of 2011 and
2012. Diversity profiles and cluster analysis were calculated in order to compare the Phytophthora
communities detected at different sites and times. Seasonal differences were observed in the species
compositions. Temperature data and basic hydrological parameters were found to determine the presence
or absence of waterborne Phytophthora species in the catchment area of the Rák Brook. Pathogenicity of
the Phytophthora species discovered was confirmed and evaluated against sessile oak seedlings.
