To assess the relative importance of fungicide input for DBA Aurora and DBA Vittaroi under overhead irrigation
• DBA Vittaroi developed higher levels of stripe rust infection than DBA Aurora but levels at mid flower were still below 5% on the flag leaf (3.5% v less than 1% on flag leaf at mid flower).
• The low levels of stripe rust infection did not generate any significant yield increases (p=0.3) when controlled with different fungicide strategies.
• The trend with DBA Vittaroi was non-significant yield increases associated with fungicide application with increases of 0.24 – 0.59t/ha with the two spray approach being the most reliable for yield and stripe rust control.
• Fungicide strategy had no significant effect on grain protein (range 14.3-15.0%) which averaged 14.7% (not shown)
• DBA Aurora at 13.9% had significantly less grain protein than DBA Vittaroi at 15.5% (not shown) but was significantly higher yielding than DBA Vittaroi at (8.04 vs 6.46 t/ha).
• The GS31 fungicide was very important to reduce initial infection but there was little additional value of Systiva seed treatment in this trial.
