Aerial damage on transplanted seedlings of Eucalyptus spp. was recorded in Italy for the first time. In 1987 a widespread infection was detected in the eucalyptus nursery of the Ovile Farm, Rome. It occurred only on E. globulus and was subject to sprinkler irrigation. In 1988 the disease occurred exclusively on E. delegarensis and E. regnans. The agent, which attacks leaves, petioles and shoots, was identified from the morphological and physiological characteristics of the isolates obtained in each year as Phytophthora nicotianae var. nicotianae.
