As part of the search for natural substances of plant origin as an alternative to chemical pesticides in agriculture, Terminalia ivorensis, to which antifungal virtues are lent, was used in this study to evaluate in vitro the sensitivity of Fusarium oxysporum. The antifungal activity was evaluated by the double dilution method on PDA medium with aqueous and ethanolic extracts at 70% leaf and bark of Terminalia ivorensis compared to Mancozan 80 WP which is a widely used reference fungicide. According to the results, only 70% ethanolic extracts have fungicidal properties on Fusarium oxysporum. The ethanolic bark extract of Terminalia ivorensis was fungicidal at CMF = 6.25 mg / mL. For ethanolic leaf extracts, the CMF was 12.50 mg / mL. The phytochemical sorting of the various extracts showed the presence of secondary metabolites which could justify the antifungal activity of Terminalia ivorensis and its use in traditional medicine.
