More than 70 Streptomyces lavendulohygtroscopicus strains were isolated from the soil samples collected under differentecological conditions. Fermentation centrifugal supernatant(FCS) of the strians were used as biological control agentsto bioassay rice disease pathogens of sheath blight (R.solani ) and bakanae ( G. fujikuroi ).
