In Côte d'Ivoire, corn (Zea mays) leaf diseases, due to fungal reduced significantly the yield. In order to control these fungi responsible of corn leaves diseases, an identification of the main pathogens was done. Antifungal activity of four plants (Azadirachta indica, Chromolaena odorata, Ricinus communis and Nicotiana tabacum) were tested in vitro and in vivo against fungi responsible for corn leaf diseases. The pathogenicity test showed that the fungus Helminthosporium sp. was the most virulent followed by Curvularia sp. All plants aqueous extract tested in this study inhibited spore germination of fungi responsible for corn leaf diseases. R. communis was the most effective aqueous extract against pathogens suppressing totally their conidia germination. The treatment of corn plot with Azadirachta indica and Ricinus communis reduced significantly incidence and severity of corn leaf diseases. These effective plant extracts may contribute to development of potentially effective alternative fungicide to control corn leaf diseases.
