Abstract
P. cinnamomi is a major pathogen in native plants of Southwestern Australia. The fungicide phosphite decreases the growth of P. cinnamomi in a range of jarrah (Eucalyptus marginata) forest species. One of the main modes of spread of P. cinnamomi in the jarrah forest is via production of zoospores from infected plants and soil. P. cinnamomi sporangia production is approximately 3.5 times more sensitive to phosphite than mycelial growth in vitro. In planta, sporangia and zoospore production is decreased but not prevented if plants in the glasshouse are infected and sprayed with phosphite.
The aim of this experiment was to determine whether phosphite prevents the production of zoospores from P. cinnamomi colonised jarrah in the field. It also examined whether zoospores produced from P. cinnamomi growing in phosphite treated plants were able to infect plant tissue
