Abstract
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.
Keywords:
ITS, biological control.
