Abstract
Blast disease is an important disease of rice plants caused by the pathogen Pyricularia oryzae which causes losses of up to 61%. Streptomyces sp. is a Gram-positive bacterium from the actinomycetes group that has the ability to produce bioactive compounds in the form of anti-fungi as an inhibitor of pathogen development. This study aims to obtain Streptomyces spp. isolates that have the potential to inhibit Pyricularia oryzae. The parameters observed were the percentage of inhibition of Streptomyces spp. against P. oryzae in dual culture antagonist test and volatile compound test. The results of the study obtained a total of eight isolates of Streptomyces spp. and the results of dual culture antagonist test obtained three isolates with strong inhibition (S1, S2, S8), three isolates with moderate inhibition (S3, S5, S6) and two isolates with weak inhibition (S4 and S7). The results of the volatile compound test, the strongest inhibition was produced by S1, S2, S8, and moderate category inhibition was produced by S3, S4, S5, S6, and S7.
