Piper genus are plants with biotechnological potential because they synthesize about 700 compounds with biological activity. In this study, we tested the fungicidal effect of ethanolic extracts obtained from six Piper species from the state of Veracruz, Mexico, against Fusarium oxysporum f. sp. vanillae. The Mean Effective Concentration (EC50) and Minimum Fungicide Concentration (MFC) were estimated, as well as preliminary phytochemical profiles and the total content of phenols, flavonoids, and alkaloids. The results showed that the extract of P. aduncum had the major inhibition potential with an estimated EC50 and CMF of 0.64 and 0.4 mg/mL. The extract of P. umbellatum had the highest concentration of alkaloids (29.51 μgEP / mg), while P. amalago had the highest concentration of flavonoids and phenols (12.82 μgEQ/mg and 8.53 μgEAT/mg). Piper extracts have a fungicidal effect against F. oxysporum, attributable to secondary metabolites, which turns them into an alternative in the search for biopesticides. [ABSTRACT FROM AUTHOR]
