First report of Eutypella parasitica in the Czech Republic
The NPPO of the Czech Republic recently informed the EPPO Secretariat of the first detection of Eutypella parasitica (formerly EPPO Alert List) on its territory. The fungus was initially detected in 1 tree of Acer pseudoplatanus displaying an old canker (135 cm long) high on the trunk (5 m high) in September 2015. The identity of the fungus was confirmed in October 2015 by morphological and molecular (PCR, sequencing) methods. An official delimiting survey was implemented. For the moment, the fungus has been found on 4 trees of A. pseudoplatanus scattered over an area of about 2 km² and located in a forest in the Moravian-Silesian region. The origin of this outbreak is unknown. Phytosanitary measures have been adopted to eradicate E. parasitica as the outbreak appears to be very limited. These measures include tree destruction by burning, as well as hygiene measures during and after the destruction. A specific survey will continue in 2016.
The pest status of Eutypella parasitica in the Czech Republic is officially declared as: Present, only in one locality, under eradication.
