Teratosphaeria pseudoeucalypti on eucalyptus in Brazil
Tropical Plant Pathology 39 (5), 407-412
Abstract: A new foliar disease caused by Teratosphaeria pseudoeucalypti on eucalyptus (E. globulus, E. urophylla x E. globulus and E. nitens x E. globulus) in Brazil is described . The disease is characterized by leaf spots of variable sizes and shapes, resulting in leaf blight and premature defoliation. Based on the morphological characteristics and multilocus phylogenetic analysis of the EF-1alpha, ß-T and ITS-2 gene regions of five isolates, the fungus was identified as T. pseudoeucalypti. This is the first report of this pathogen outside Australia and a method for sporulation in culture is described.
