| Abstract: | In order to identify the pathogenic fungi of Atractylodes macrocephala root rot in Baoding, Hebei Province, eighty strains of Fusarium species were isolated from 120 A. macrocephala plants with root rot symptoms with the isolation frequency at 66.7%. Fusarium species were identified by molecular techniques with specific primers, TEF-1α gene sequencing together with morphological characteristics. Thirty-nine F. solani strains were identified with the highest percentage at 48.8%, and 32 F. oxysporum strains were isolated with the percentage at 40.0%. Seven F. equiseti and two F. brachygibbosum strains accounted for 8.8% and 2.5%, respectively. The pathogenicity test on A. macrocephala showed that F. solani and F. oxysporum caused the typical symptoms of root rot. Koch's postulates were fulfilled following re-isolation and identification of the isolates of F. solani and F. oxysporum. Taken together, the results showed that F. solani and F. oxysporum were the pathogens of A. macrocephala root rot in Baoding, Hebei Province. |
