Cuttings of the Wollemi Pine, Wollemia nobilis, were inoculated with Phytophthora cinnamomi, Botyosphaeria sp., Rhizoctonia sp., Fusarium oxysporum and F. solani. P. cinnamomi and the Botyosphaeria sp. were pathogenic causing plant death over a period of up to 5 weeks. None of the other fungi caused significant disease although two out of nine plants inoculated with F. oxysporum died during the experimental period. The results confirm the necessity to maintain strict hygiene and entry controls on the site where this extremely rare plant is found.
