Foliar fungal pathogens are a significant threat to grain production and productivity in Australia. The diversity and impact of foliar pathogens continues to grow across all major production areas. The drivers increasing pathogen impact include:
  • Reliance on a narrow genetic range of host cultivars
  • Tightening of crop rotations and the removal of the pasture phase
  • Adoption of agronomic practices (for example stubble retention) and host genetics (for example, early vigour) which optimise infection pressure
  • Increased use of fungicides placing selection pressure on both target and non-target organisms
  • Continued introduction of new pathogens and strains
  • Evolution and selection for more pathogenic strains
  • Breakdown of host resistance
  • Climate change and variability
  • Limited genetics deployed by breeding programs
Collectively, these drivers set the scene for an 'arms race' between host and pathogen whereby the pathogen has by far the greatest agility in comparison to changes in both host genetics and farming practices. The most harmful pathogens are those that are highly dynamic and undergo several cycles of asexual and/or sexual reproduction within a season. This, combined with high population numbers, natural mutation rates and consistent selection pressure, enable frequent shifts in pathogen genetics and impact. On the other hand, Australian farming systems, and a focus on genetic gain for yield and abiotic stress, necessarily create a conducive environment for pathogen impacts.
The CCDM is a strategic partnership between GRDC and Curtin University that was established as a national centre to address this increasing fungal pathogen impact. CCDM focusses upon capacity building, research activity and industry development to minimise the impact of foliar pathogens (other than rust) and fungicide resistance. The nature of CCDM and its research co-investment allows multidisciplinary teams to tackle major fungal pathogens of cereals, pulses and canola from several different directions. For each pathosystem the research focuses on understanding the pathogen through its genomics and population structure, examining host and pathogen interactions, developing new forms of host resistance and breeding tools, and by investing in optimising the use of fungicides and other control measures.

Monitoring and analysis of pathogen populations by CCDM in 2021 revealed new resistance mutations affecting fungicide performance for the first time in Australia and, in other cases, existing mutations being more widespread and affecting more states.
