Aims

To look at the significance of the cultivar difference with regard to management strategy.

Key messages
  • Early sown (10th April) SQP Revenue was significantly more responsive than Manning to a programme of agrichemicals for foliar disease and Barley Yellow Dwarf Virus control (BYDV)
  • Ungrazed SQP Revenue gave a significant 0.66 t/ha response to a two spray fungicide programme and a further 0.28 t/ha response to an additional insecticide programme for BYDV control, compared to a maximum response of 0.39 t/ha for both fungicide and insecticide for Manning
  • Simulated grazing did not significantly reduce yield with either cultivar and gave an average dry matter benefit of 1.89 t/ha with laxed grazing at GS16 & GS30 and 2.39 t/ha with laxed grazed followed by a hard grazing at the GS30
  • Leaf rust Puccinia triticina which was the principal disease in the trial was at significantly higher levels in SQP Revenue than Manning and required two foliar fungicides to give control
  • In SQP Revenue grazing was not an effective control measure for leaf rust control compared to an early GS31 fungicide when assessed at flag leaf
  • At the Westmere site, simulated grazing reduced grain yield by 0.2-0.5 t/ha compared to 1.7 t/ha dry matter removed by grazing
  • Low levels of disease at this site did not allow the hypothesis that grazing reduces disease pressure to be tested.

Acknowledgments

The research presented in this paper has been made possible by the significant contributions of growers through both trial cooperation and the support of the GRDC (CSP00178), the authors would like to thank them for their continued support, with special mention of the Hamilton and McCrow families, for allowing us the use of their land for the 2015 trials.

A collective thanks goes to all staff members of CSIRO, FAR Australia and SFS who have been involved in the project over the years.
