  • Among 110 isolates of actinomycetes isolated from ginseng pathogen-suppressive soils, the three actinomycetes showing the effective controls to Fusarium solani or Cylindrocarpon destruc­tans causing ginseng root rots were identified according to their morphological, cultural and physio­logical characteristics on various culture media. Spore chains of K 6-2, S 2-1 and Y 2-2 were Spira (S), Retinaculum-apertum (RA) and Rectus-flexibilis (RF), respectively. Spore surfaces of K 6-2 were spiny, whereas S 2-1 and Y 2-2 were all smooth. Aerial mass colors of 3 isolates were gray series. As a result of various tests, they were identified as Streptomyces variabilis, Streptomyces virgi­niae and Streptomyces griseo/us, respectively.
