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.

Effects of the chemical composition of essential oils from seven plants used in traditional medicine in Benin on the growth of eleven pathogenic bacteria in antimicrobial control

“…For the genus Cymbopogon, the yield obtained for C. schoenantus (1.88%) is much lower than those obtained for the same plant in Benin, in Djougou (3.49%; [6] ), in Boukounbe (2.8%; [21] ) for dried leaves. On the other hand, the yield of C. nardus (1.06%) is lower than that obtained in Benin at Abomey-Calavi (6.88%; [22] ). Similarly, the yield of C. citratus (0.71%) is much lower than those obtained for the same plant in Benin at Abomey-Calavi (4.31%; [22] ), at Akogbato (1, 7%; [21] ) for dried leaves.…”

Post-Harvest Control of Anthracnose of Mango (Mangifera indica L. var Kent) using Essential Oils Extracted from two Aromatic Plants (Cymbopogon citratus (D C) Stapf. and Melaleuca quinquenervia L.) of the Ivorian Flora

“…Along with the growth measurement, the Minimum Inhibitory Concentration (MIC) was detected. MIC was considered as the lowest concentration of the product used at which no mycelial growth or spore germination was observed (20).…”

“…(Cowpea) is an important legume of African origin with high protein content. It is cultivated in tropical and subtropical regions like sub-Saharan Africa and widely distributed throughout the world [1][2][3]. The world's annual production of cowpea is about 7 million tons of dry seeds, of which more than 96% are produced in Africa and 186,000 tons by Cameroon [4].…”
