First report of Phytophthora quercina in Austria

Phytophthora quercina (EPPO Alert list) was isolated from mature oak trees of several species (Quercus robur, Quercus petraea, Quercus pubescens) in the eastern part of Austria during surveys in 1999-2000. Soil samples including necrotic fine roots were collected and leaf baits were used to study the presence of Phytophthora species. P. quercina was the most common species and was found in 11 of 35 sites. Other Phytophthora spp. included P. citricola, P. syringae, P. gonapodyides, P. europaea. The authors conclude that these results suggest that P. quercina is widely distributed in oak forests in Austria and may play an important role in oak decline in certain oak ecosystems in Austria.
