Tubakia dryina, symptoms and pathogenicity to Quercus robur

Tadeusz Kowalski

Abstract


In 1999 disease symptoms on leaves of Quercus robur – necrosis, deformation and blackening of leaf petiole, followed by premature leaf fall were observed. Tubakia dryina was isolated from necrotic tissues and its pathogenicity to oak proved in infection experiments. The fungus caused necrosis of shoots and leaves. Dying leaves displayed also blackening of leaf petiole.
