Abstract
Canker disease agents were determined by using samples collected from diseased chestnut trees from eleven provinces of Black Sea Region of Turkey. Cryphonectria parasitica was isolated from 52% of the samples and it plays an important role on the dieback of chestnut forests in this region.
The cankers caused by this pathogen have been recovering in some places in which hypovirulence may play the important role.
Along with hypovirulence other antagonistic fungi, such as Trichoderma and Penicillium, were frequently isolated and they might be involved in this process.
The other canker causing fungi were Pestalotiopsis funerea, Diaporthe (Anam. Phomopsis) castenea, Botryosphaeria dothidae (Anam. Fusicoccum aesculi) and Valsa sp. P. funerea and D. castenea were recovered from the entire Black Sea Region from 7.2% and 6.78% of the samples respectively. B. dothidae was found in 6 provinces at a low percentage (1.81 %). A Diplodina sp. and Valsa (Anam. Cytospora) sp. were isolated from 4 and 2 provinces at very low rates (1.5 and 0.26 %) respectively.
Pathogenicity of P. funerea, D. castenea, B. dothidae, was proved on chestnut but Valsa sp. has not been tested so far. Diplodina sp. did not cause any symptoms on chestnut stems.
