(2019): Characterisation and pathogenicity of Cryphonectria parasitica on sweet chestnut and sessile oak trees in Serbia. Plant Protect. Sci., 55: 191–201. Abstract: The presence of Cryphonectria parasitica (Murrill) M.E. Barr was studied in six natural and planted stands of sweet chestnut in Serbia. The fungus was detected on the sweet chestnut in five localities and on the sessile oak in one locality. In total, 77 isolates from the sweet chestnut and five isolates from the sessile oak were obtained. Based on the culture morphology, all the obtained isolates were proven to be free from Cryphonectria (Saccardo) Saccardo & D. Saccardo hypovirus. The isolates of C. parasitica from the sweet chestnut were compatible with three different vegetative compatibility types, EU-12, EU-2, and EU-1, while the isolates from the sessile oak belonged to EU-12.
