Yield impact of crown rot and sowing time on winter cereal crop and variety selection – Tulloona 2015 locations
Aims

To examine the impact of crown rot on yield and grain quality in a range of durum, bread wheat and barley varieties across two sowing times near Tulloona in north-western NSW in 2015. 

Key messages
  • Sowing date and variety maturity choice is a balance between the risk of frost versus terminal heat stress.
  • Earlier sowing can increase frost risk, but also generally maximises yield potential and reduces the extent of yield loss from crown rot.
  • Cereal crop and variety selection can have a significant impact on yield where there are high levels of crown rot infection.
  • Durum wheat, barley or bread wheat varieties with increased susceptibility to crown rot, should only be grown in paddocks known to have lowrisk inoculum levels based on testing (e.g. PreDicta B).
  • All winter cereal varieties are susceptible to crown rot infection and will not significantly reduce inoculum levels for subsequent crops. Cereal crop and/or variety choice is not the sole solution to crown rot.

Acknowledgments

The research undertaken as part of projects DAN00175: National crown rot epidemiology and management program and DAN00167: Variety Specific Agronomy Packages for southern, central and northern NSW; is made possible by the significant contributions of growers through both trial co-operation and the support of the GRDC, the authors would like to thank them for their continued support. This project is co-funded by the NSW state government through NSW DPI who are also thanked for their support in fully funding two of our positions and for laboratory and other infrastructure costs. Soilborne pathogen levels were determined using the DNA based soil test service PreDicta B provided by the South Australian Research and Development Institute. Technical assistance provided by Stephen Morphett, Jim Perfrement, Jan Hosking, Mick Dal Santo, Robyn Shapland and Patrick Mortell is gratefully acknowledged. We finally thank Jack and Julia Gooderham for allowing us to conduct this trial
