First Record of Eutypella parasitica on Maples in Urban Area in Croatia


Background and Purpose: Eutypella parasitica, a plant pathogenic fungus attacking maples (Acer spp.) was detected for the first time in Croatia in 2007. From 2007 to 2014, it was found only in forests, on several trees in Hum na Sutli, near Slovenian border. In 2015, the presence of Eutypella parasitica was monitored for the first time in urban areas. Materials and Methods: Within the official survey programme, 23 visual surveys were conducted and 24 samples were collected and analysed for the presence of fungi. E. parasitica was found in Bundek Park in Zagreb. Typical symptoms of Eutypella canker were detected on two field maples (Acer campestre) and two boxelder maples (Acer negundo). Twelve isolates were collected from symptomatic trees. Conclusions: Eleven out of twelve isolates from four trees were confirmed as E. parasitica by species-specific polymerase chain reaction. This is the first report of E. parasitica in Zagreb, the first record of E. parasitica in Croatia outside forests, as well as a record of a new host species in Croatia, boxelder maple (A. negundo). Introduction pathway of E. parasitica in Zagreb remains unknown
