Abstract: Streptomyces scabies and S. acidiscabies, the two major phytopathogens induce potato common scab in potato growing areas of Iran. Soil Actinomycetes including 174 isolates were assayed for assessing antagonistic activity against Streptomyces scabies and S. acidiscabies. From tested isolates, S. olivaceus, strain 115 and S. plicatus, strain 101 showed high anti-scab activity revealed by bioassays in agar disk and well diffusion methods. For further biological characterizations, the active strains were grown in submerged cultures to determine growth curve and prepare crude extracts. Preliminary greenhouse studies indicated that amending soil with the S. olivaceus, strain 115 and S. plicatus strain 101 reduce crop losses due to the pathogens. Antibacterial activities of both antagonists were of bactericidal type on both pathogens with complete inhibitory effects.
