Methodology and Results: Sampling was carried out in a few large cowpea retail store located in the markets of Dantokpa (Cotonou) and Ouando (Porto-Novo), followed by research and isolation of the alteration mycoflora. Antifungal tests were carried out with various essential oils in other to assess their antimicrobial potential. Kpatinvoh et al., J. Appl. Biosci. 2017 Efficacité des huiles essentielles de trois plantes aromatiques contre la mycoflore d'altération du niébé collecté dans les magasins de vente du Sud-Bénin 10681Results obtained, indicated that the microbial strains isolated from the cowpea samples are essentially Aspergillus flavus (L.), Aspergillus tamarii (K.) and Penicillium roqueforti (T.). Antimicrobial tests have demonstrated that essential oils have high antimicrobial activities against fungal flora contaminating cowpea with minimal inhibition concentrations depend on fungi and the dose of essential oil tested. The highest antifungal activities were obtained with essential oils from Cymbopogon citratus (L.) and Cymbopogon nardus (L.) with MIC ranged from 0.05 to 1µl/ml. Conclusion: The antifungal potential of these plants therefore offers an innovative approach in the management of cowpea stocks in southern Benin.
