摘要

Abstract 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, Fusariu.
