Rice is a crop of global importance, susceptible to infection by phytopathogens, among which the fungus Pyricularia oryzae stands out. Given the need for alternatives, microorganisms, mainly marine, were selected for the control of P. oryzae. Of the organisms selected, Streptomyces sp. PNM 87 showed the best in vitro control. The active fractions were found to be rich in surfactins, suggesting that the biological activity found is associated with the presence of this lipopeptide family. In conclusion, Streptomyces sp. PNM 87 effectively controls P. oryzae, and its action is attributed to the production of lipopeptides.
