Abstract: Isolates of Oidium spp. from Eucalyptus pellita were compared to Erysiphe cichoracearum, obtained from Dahlia sp. and Sphaerotheca pannosa, from Rosa sp. Based on the morphological characteristics of the anamorph, it was concluded that the Oidium isolate from eucalypt was similar to the isolate from rose identified as S. pannosa. Inoculations of Oidium isolates from all studied host species showed that S. pannosa obtained from eucalypt and rose, and E. cichoracearum from Dahlia sp. were pathogenic to seedlings of Eucalyptus pellita, one of the most susceptible species to the pathogen, under greenhouse conditions.
