Occurrence of the fungus Cryphonectria parasitica was found in the Petrovce village, district Sobrance. The fungus was successfully isolated from 11 samples. Based on the culture phenotype, all isolates were considered to be virulent. No hypovirulent strains were found. Each isolate was unambiguously assigned to a simple vc type. According to the European nomenclature, the vc type detected in Petrovce is EU 12. Hypovirulent isolates were prepared for biological control of chestnut blight in Petrovce.
