Absence of Mycosphaerella dearnessii in Czech Republic
Mycosphaerella dearnessii (Ascomycetes, Dothideales – EPPO A2 quarantine pest) has never been found in Czech Republic. In 2000, only one consignment of Pinus nigra imported from Hungary was intercepted with symptoms of this pathogen, whose identity was later confirmed by testing. However, the NPPO of Hungary officially stated that this pathogen is absent from their country, as a result of surveys (inspections and laboratory tests) carried out in both nurseries and forests.
The situation of M. dearnessii in Czech Republic can be described as follows: Absent, intercepted only.
