Impact of winter cereal crop choice and sowing date on final soil populations of Pratylenchus thornei – Tulloona 2015 locations
Aims

To examine the effect of two sowing dates on final Pt populations in a range of durum, bread wheat and barley varieties near Tulloona in north-western NSW in 2015.

Key messages
  • Winter cereal crop and variety choice can have a large impact on Pratylenchus thornei (Pt) population build-up within paddocks.
  • Averaged across winter cereal entries, final Pt densities were 83% higher when sown in early May compared with early June.
  • Final Pt populations were between 1.6 and 4.7 times higher in 14 of the 24 barley entries, the durum line 190873, and 12 of the 19 bread wheat entries when sown in early May compared with early June.
  • The additional population build-up with early May sowing generally increased the risk level for yield loss in the following wheat crop from either low to medium, or medium to high compared to sowing in early June.
  • Although earlier sowing can reduce yield loss associated with both crown rot (CR) and Pt, it does, however, appear to favour higher Pt population development in some winter cereal varieties, which could exacerbate negative consequences on following crops and/or varieties in the rotation.

Acknowledgments

This research is part of the projects National crown rot epidemiology and management program (DAN00175) and Variety Specific Agronomy Packages for southern, central and northern NSW (DAN00167) with joint investment by NSW DPI and GRDC. Thanks to Jack and Julia Gooderham for providing the trial site and Jim Perfrement, Mick Dal Santo and Stephen Morphett (NSW DPI) for sowing, maintaining and harvesting the trial. Thanks to Robyn Shapland, Jason McCulloch, Rachael Bannister, Carla Lombardo, Patrick Mortell and Chrystal Fensbo (NSW DPI) for collecting post-harvest PreDicta B soil samples. Root lesion nematode levels were determined using the DNA-based soil test service PreDicta B provided by the South Australian Research and Development Institute.
