Effectiveness of Essential Oils from Three Medicinal Plants Against Bayoud Disease (Fusarium oxysporum f. sp. albedinis) of Date Palm (Phoenix dactylifera L.)

Plant extracts and essential oils are promising new sources of non-toxic alternatives to chemicals substances. They used for their antimicrobial properties against plant diseases fungal origin, bacterial, those virus origin. This study was carried out the antifungal activity Artemisia herba-alba, Foeniculum vulgare Citrus sinensis Fusarium oxysporum f. sp. albedinis. Essential oil extracted by steam distillation. Antifungal investigated macro-broth method dilution a minimal inhibitory concentration (MIC) assay this pathogen. The yield obtained distillation samples 2.31% greater than that from sample which 1.8%, followed herba alba 1.22%. Regarding activity, results revealed better tested strainsat lowest LC50 values (0.1 µl/ml). On other hand, vulgare, show similar MICs mycelial growth value MIC CMF is 50 µl/ml three oils.
