The European chestnut was evaluated for Chestnut blight disease in the Modrý Kameň region, in 2010. A total of 1321 trees and sprouts were selected. There were 140 healthy trees, without any symptoms of Cryphonectria parasitica infection. Nearly 90% of the evaluated trees and sprouts were diseased. The health condition index (I HC ) on 11 experimental plots varied from 2.31 to 4.03. Every collected sample was identified as having C. parasitica. All isolates had the orange culture morphology; all isolates were virulent. Among the isolates, 8 vc types were detected. Vc type EU-2 was dominant, it comprised 37.14% of the tested isolates. Two other vc types: EU 1 and EU 12 were frequently detected.
