Occurrence and pathogenicity of Corinectria spp. - an emerging canker disease of Abies sibirica in Central Siberia
During recent years, a new disease of Siberian fir (A. sibirica) emerged in Central Siberia, exhibiting symptoms of stem/branch deformation, cambium necrosis, and dieback of branches and twigs, the causal agent remaining unknown. The aim was to identify agent of the disease and to investigate its pa...
