Abstract
A high incidence of root and crown rot of strawberries was observed in production districts in the Swan Coastal Plain north of Perth during 2005 and 2006. Fifty samples of affected and asymptomatic plants were collected randomly. Crown and roots of individual plants were examined and soil surrounding roots was tested for soilborne pathogens. Fusarium oxysporum f. sp. fragariae was consistently isolated from crowns and Phytophthora cactorum was detected from roots, crowns and soil as a major pathogen. Results of this study showed that several pathogens such as Pythium spp., Phoma spp., Rhizoctonia spp., Colletotrichum spp. and Macrophomina spp. were associated with the root and crown rot of strawberries.
