The cultivation of rice needs pesticide applications to combat problems of pathogenic microorganisms. The problem of resistance to these substances is increasing, so other methods are   needed to replace these practices. An alternative to solve the appearance of diseases of fungal origin is the use of bacteria as a biological control of phytopathogenic fungi. An alternative is bioremediation, which uses beneficial microorganisms that compete and inhibit pathogens. In this work, the capacity of the EM commercial product that consists of a group of bioremediating microorganisms is evaluated. Samples were taken in three plots with application of EM and three plots without application of the product. The samples were subjected to a total count and fungus analysis. The results were statistically compared, and they showed differences in the total count, but not in fungi. In the samples of MS, strains were found capable of producing inhibitors against other microorganisms.
