The present study was conducted to identify the antifungal activity of phenolic compounds extracted from the mangrove, Rhizophora mangle against the Fusarium verticillioides isolates DA42, F64 and PO3. The total phenolic content was calculated using the Folin-Ciocalteu method. The in vitro inhibition test was performed according to the poisoned food technique. Stem extracts had the highest total phenolic content (9.5 mg GAE/g DM) and displayed major inhibition percentages against all F. verticillioides isolates. Furthermore, the concentration of this extract required to inhibit the three fungal isolates by 50 %, is 2 to 3 times greater on average than that required for leaf and root extracts. This study demonstrated the inhibitory activity of ethanol extracts of Rhizophora mangle roots, stems and leaves against different isolates of Fusarium verticillioides.
