Abstract
Pittosporum undulatum is a potential Australian host of Phytophthora ramorum, the causal agent of sudden oak death in California. It was susceptible and supported sporulation in zoospore inoculations of detached leaves. Susceptibility and sporulation potential were low when compared to Umbellularia californica. Two independent positives were obtained from symptomatic trees in a PCR-based assay using species-specific primers. Foliar symptoms observed on the trees were replicated in the detached leaf inoculations.
Keywords:
horticulture, oomycete, nursery, sporulation, sudden oak death.
