Abstract :
This study was conducted in 2009 to determine the pathogenicity of Fusarium species isolated from sugar beet (Beta vulgaris L.) plants in Pasinler district of Erzurum. A total of 194 Fusarium isolates were obtained in isolation studies. Of these isolates, 37.63% were F. equiseti, 31,44% were F. oxysporum, 13,92% were F. acuminatum, 10,82% were F. solani, 4,12% were F. heterosporum, 1,55% were F. avenaceum, and 0,52% were F. graminearum. Pathogenicity tests on sugar beet isolates belonging to F. acuminatum (P2-8A1), F. equiseti (P1-6), F. heterosporum (P10-30), F. oxysporum (P8-24, P9-36) and F. solani (P8-2) were found to be more virulent than the other Fusarium isolates. Sugar beet was found to be a new host of F. acuminatum and F. graminearum in Turkey.
