【 摘 要 】

Sansevieria trifasciata plants showing symptoms of leaf blight were observed in Teresina City, Brazil. Based on morphology and the phylogenetic analysis of DNA sequences of the EF-1α and ITS regions, two isolates of Neoscytalidium dimidiatum were identified. Pathogenicity tests showed that the isolates caused leaf blight on S. trifasciata, in addition to Sansevieria cylindrica, and fulfilled Koch’s postulates. To the best of our knowledge, this report is the first to describe N. dimidiatum on Sansevieria in Brazil.
