First report of Eutypella parasitica in Croatia
In Croatia, a survey for Eutypella parasitica (EPPO Alert List) was performed in September 2007 along the border with Slovenia, as a Pest Risk Assessment had showed than more than half of Croatia was at high risk for E. parasitica establishment (Ogris et al., 2006). In Prišlin (less than 1 km from the border with Slovenia), 13 Acer campestre trees showing typical symptoms of Eutypella canker were observed. 2 trees had young cankers, 9 presented old cankers and 2 trees had already collapsed due to the progress of the disease. Surprisingly, E. parasitica was not observed on A. pseudoplatanus trees which were abundant near the infected area. E. parasitica was identified on the basis of morphological characteristics and by PCR with specific primers. This is the first report of E. parasitica in Croatia.
The situation of Eutypella parasitica in Croatia can be described as follows: Present, first detected in 2007 on Acer campestre at Prišlin, close to the Slovenian border.
