In vitro evaluation of antifungal activity of Moringa oleifera Lam extracts against coffee wilt pathogen, Gibberella xylarioides Heim and Saccas

The Moringa oleifera extracts were investigated for antifungal activity against coffee wilt pathogen Gibberella xylarioides as a first step in the screening of the extracts for preliminary fungicides properties on coffee using micro dilution method. In vitro evaluation revealed that, M. oleifera leaf, seed, flower and stem bark extracts exhibited broad spectrum activity against the test organism with minimum inhibition concentration (MIC) range from 0.37 mg/mL to 3.125mg/mL. M. oleifera roots back extracts appeared to be less effective against G. xylarioides with MIC at 6.25 mg/mL. Results of this study have shown the potentials of M. oleifera extracts as fungicides by inhibiting the growth of the test organism.
