First report of T eratosphaeria zuluensis causing stem canker of E ucalyptus grandis in U ganda

Summary Teratosphaeria stem canker is one of the most important diseases to have emerged on non‐native plantation‐grown E ucalyptus trees globally. In 2012, E ucalyptus grandis trees with typical T eratosphaeria stem canker symptoms were observed in U ganda. Multigene sequence analyses of isolates from these cankers led to the identification of T . gauchensis , previously recorded in U ganda, and T . zuluensis . This study represents the first report of T . zuluensis in U ganda. Furthermore, this is the first report of the co‐occurrence of T . zuluensis and T . gauchensis in a single area.
