Plant growth regulators: what value do they have in the HRZ of Victoria locations
Aims

The purpose of these trials was to investigate the value of applying the PGR Moddus EVO to barley grown in the high rainfall zone of Victoria to reduce lodging and improve yields.

Key messages
  • Moddus Evo reduces lodging and can increase yields
  • Application timing and concentration of Moddus Evo is critical
  • Moddus Evo should not be applied to plants under stress
  • Moddus Evo has improved formulation stability and plant uptake

The key message that came out of these trials is that despite the lack of lodging, a Moddus application at 400ml/ha applied at GS31, with or without a second application of Moddus at 200ml/ha at GS37, had a beneficial effect on yield and reduced crop height. These results are supported by previous research on PGR use in cereals.
