Formatted Abstract/Summary Sorghum lodging is a continual, but increasing, threat to sorghum producers in northern New South Wales and Queensland, particularly on the Darling Downs and in central Queensland. Although, the pathogens that cause charcoal rot (Macrophomina phaseolina) and fusarium stalk rot (Fusarium species) are known to play a role in lodging, their distribution and relative importance in the major sorghum growing regions in Queensland is unknown. The causal agent of fusarium stalk rot was previously known as Fusarium moniliforme, however it has now been separated into a number of species. These taxonomic changes have led to the need to gain an understanding of the role that different Fusarium species play in sorghum lodging in Australia. Surveys are being undertaken throughout the major sorghum-producing regions in Queensland to identify the Fusarium species associated with stalk rot and lodging, and to determine their distribution and relative importance. Also, information on agronomic practices and other factors which influence stalk rot and lodging in sorghum will be collected during the surveys. Overseas research has demonstrated that there is resistance to some Fusarium species in grain sorghum germplasm, so a robust screening protocol will be developed to identify sources of resistance to the dominant stalk rotting Fusarium species in Australia. The findings from these activities will assist in the planning and implementation of farming systems-scale research, ultimately leading to the development of integrated disease management packages. This project is a collaborative effort between the DEEDI summer field crops pathology team, the Grains Research and Development Corporation (GRDC), The University of Queensland, and the Northern Grower Alliance.
