Inhibiting efficacy of metabolites of Streptomyces lavendulohygtroscopicus and its ultraviolet induced strain on two rice diseases

摘要

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