Key Points
- Fungicide treatments gave significant control of stripe rust and increases in yields
- MOCC varied up to $188/ha. Multiple applications of reduced rates of fungicide gave reasonable returns
- Early effective control of stripe rust was important for the continued benefit of the subsequent treatments to be realised
- There was a positive correlation between green leaf area of the flag and leaf 2 and final yield. Loss of GLA 72 days before harvest was directly attributable to stripe rust
- Disease pressure was low in this crop and further research is needed to confirm these trends
