Hyper Yielding Crop Wheat Disease Management x Variety - VIC

• Fungicide input was not cost effective when applied to Longford and AGTW005 at the Victoria research site.
• As a result of stripe rust infection RGT Cesario gave significant yield and margin improvements when full fungicide protection (4 units of fungicide) was applied.
• Although yield increases were much smaller and not significant Stockade gave its highest yield and margin under a single flag leaf spray, however the dry spring protected this variety from severe Septoria tritici blotch (STB) infection which was present in the base at early stem elongation.
• Fungicide management and cultivar affected grain protein in this trial, but the only effects on test weight and screenings were due to variety.
• AGTW005 had the highest yields and grain protein overall but unfortunately after four years in HYC trials it is not being commercialised.
