The crude extract of F. séptica showed a strong inhibitory activity against C. acutatum with MIC by 0.9% (w/v).
Treatment with the leaf extract of F. séptica at concentrations of 1 to 5% (w/v) under in vitro test significantly
suppressed the growth of Colletotrichum spp, the cause of anthracnose disease on chili pepper. This treatment
effectively reduced the fungal radial growth on PDA, spore’s formation and biomass formation on PD broth
médium with the inhibitory activity ranged from 29.72% to 100%. This result suggested that the leaf extract of F.
séptica contains antifungal substances responsable for the antifungal acivity against C. acutatum and can be
considered as one of alternative tools to control anthracnose disease on chili pepper.
