The aim of this experiment was to investigate the role of flowering time in upper canopy infection development, and determine any associated yield penalty.
• Blackleg infection of flowers, pods, branches and upper stems can be collectively termed as upper canopy infection (UCI).
• Early flowering of canola increases the risk of UCI.
• Fungicide can reduce disease levels and increase grain yield, but does not provide full disease control.
• Matching sowing date and varietal phenology so that flowering occurs in late winter will reduce UCI.

1. Nil. 2. Seed and fertiliser fungicide – Jockey® Stayer® (167 g/L fluquinconazole) applied to seed at 20 L/t and Intake® Combi Sapphire (500 g/L flutriafol) applied to MAP at 2.85 L/t. 3. Seed and fertiliser plus early foliar fungicide – as for treatment 2 plus application of Prosaro® (210 g/L prothioconazole and 210 g/L tebuconazole) at bud visible stage. 4. Seed and fertiliser and early foliar fungicide, plus flowering foliar fungicide – as for treatment 3 plus two applications of Prosaro® during flowering, targeted at 20% bloom and 50% bloom. This treatment is termed as ‘full’. |
