AB  - Essential oils (EOs) derived from medicinal plants are gaining recognition as sustainable alternatives to synthetic fungicides in the management of plant pathogens. This study investigates the chemical composition, chromatographic profile, and antifungal of <i>Mentha rotundifolia</i> essential oil against <i>Fusarium oxysporum</i> f. sp. <i>albedinis</i> (Foa), the pathogen responsible for Bayoud disease in date palm. The oil was extracted through hydrodistillation and characterized using thin-layer chromatography (TLC) and gas chromatography–mass spectrometry (GC-MS), revealing multiple fractions corresponding to terpenoid constituents and 23 chemical constituents, predominantly oxygenated monoterpenes (68.51%), with piperitenone oxide as the major component (62.53%). The antifungal efficacy was evaluated against ten (10) isolates of F.o.a across seven (07) concentrations different concentrations. (0; 0.25; 0.5; 0.75; 1; 1.25; 1.5μL/mL). The results obtained show a progressive decrease in the diameters of the colonies of F.o.a isolates by increasing the doses of EOMR. The percentage of inhibition varies from 7.82 to 83.41%; However, the dose of 1.75μL/mL showed 100% inhibition for all F.o.a isolates tested. These outcomes demonstrate the potential of <i>M. rotundifolia</i> essential oil as a natural, environmentally friendly antifungal agent, supporting its application in sustainable management strategies for Bayoud disease in date palm.
