First record of Passalora calotropidis in Australia and its generic position.

摘要

Passalora calotropidis has been found for the first time in Australia on rubber bush (Calotropis procera) in northern Queensland where it was associated with a damaging leaf spot disease. Analysis of sequence data of the ITS region indicated that P. calotropidis belonged to a group that consisted of species of Pseudocercospora. The generic position of P. calotropidis and its potential for biological control are discussed.
