Why are many fungicide lead compounds active against pathogens in axenic culture but inactive when applied to infected plants? It is much cheaper and easier to screen compounds for fungicidal activity in vivo (that is against the fungus grown in axenic culture) than to test in planta. However, it is commonly observed that compounds active in in vivo screens do not subsequently prove to be active in planta. The aim of this project is to investigate the physiological, biochemical and genetics basi ....Why are many fungicide lead compounds active against pathogens in axenic culture but inactive when applied to infected plants? It is much cheaper and easier to screen compounds for fungicidal activity in vivo (that is against the fungus grown in axenic culture) than to test in planta. However, it is commonly observed that compounds active in in vivo screens do not subsequently prove to be active in planta. The aim of this project is to investigate the physiological, biochemical and genetics basis of this discrepancy and to attempt to provide tools that circumvent the problem. It is expected the project will generate novel information on the environment in the plant experienced by the fungus.Read moreRead less
Role of soil factors and transmission on propagation material of fungal pathogens in the severity of strawberry crown and root disorders. Through identification of the pathogen complexes associated with root and crown disorders, their impacts, understanding the influences of environmental conditions and rotational species, knowing the sources of major pathogens, and identification of varietal resistances to the pathogens, this project will provide a unique opportunity for growers to better manag ....Role of soil factors and transmission on propagation material of fungal pathogens in the severity of strawberry crown and root disorders. Through identification of the pathogen complexes associated with root and crown disorders, their impacts, understanding the influences of environmental conditions and rotational species, knowing the sources of major pathogens, and identification of varietal resistances to the pathogens, this project will provide a unique opportunity for growers to better manage such disorders of strawberries occurring across southern Australia. Benefits include prevention of severe losses in strawberries, making strawberry production and exports more viable, sustainable and environmentally friendly, addressing the National Research Priority 'An Environmentally Sustainable Australia' and the Priority Goal of 'Transforming existing industries".Read moreRead less
