Diversity within and between Cryptodiaporthe melanocraspeda populations on Banksia spp. and variation in susceptibility within B. coccinea that resulted from pathogen-induced selection, was investigated. Genetic distances between C. melanocraspeda is

Isolations from diseased plants and controlled inoculations indicate that the host range of the canker pathogen Luteocirrhus shearii is mainly limited to Banksia. Branches exhibiting canker symptoms were sampled from the Geraldton Sandplains, Swan Co

The effect of forest environments on the expression of intraspecific resistance in Eucalyptus marginata to Phytophthora cinnamomi was determined in three Jarrah Forest bioregion provenances. Temperature was varied by inoculating in summer and winter.

Ex-situ comparison of Phytophthora cinnamomi habitat suitability of soils from a topographic gradient across the Swan Coastal Plain from dunes to a forested peneplain provides clues to the influences of soil type on disease development. Only ex-situ

The capacity of Phytophthora cinnamomi to sporulate and release zoospores in northern jarrah forest bauxite mining soils sampled in summer, winter and spring was determined. Soil types examined were a surface jarrah forest soil, a Bassendean sand and

Habitat suitability for P. cinnamomi was com- pared between soils from the major soil groups of the Fitzgerald River National Park. Because of the mainly disease-free status of the National Park, only ex-situ testing was possible by Gradsect sampling

The influence of site on effectiveness of low-volume spray of phosphite for the control of Phytophthora cinnamomi was compared between sites differing in soil nutrient status. The sites ranged from infertile deep grey sands to a red loam in the Esper
