[en] We recovered 116 fungal isolates in 7 genera from waterhyacinth plants having pronounced blight symptoms collected in Mali. Isolation frequency of the genera was Curvularia (60.32%), Fusarium (42.92%), Alternaria (11.6%), Coniothyrium (11.6%), Phoma (3.48%), Stemphylium (3.48%), and Cadophora (1.16%). On the basis of in vivo pathogenicity tests in which the diseased leaf area percentage and disease severity were visually estimated using a disease severity index, three isolates, Fusarium sp. Mln799, Cadophora sp. Mln715, and Alternaria sp. Mlb684 caused severe disease. These were later identified as Gibberella sacchari Summerell & J.F. Leslie, Cadophora malorum (Kidd & Beaumont) W. Grams, and Alternaria sp. respectively. This is the first report to highlight C. malorum as a candidate biocontrol agent against waterhyacinth.
Neither C. malorum Mln715 nor Alternaria sp. Mlb684
in host specificity tests showed any pathogenicity toward 17
crop plants of economic importance in Mali.
