To determine the effectiveness of fungicide strategies for a susceptible canola cultivar grown under overhead irrigation
• The highest yield (4.17 t/ha) was achieved with Flutriafol (in furrow) and Miravis (based on 90 g/ha ai pydiflumetofen) at 4-6 leaf, this was higher yielding (not significant) than the untreated plots (3.89 t/ha) and gave 88-94% control of stem canker (blackleg) infection (incidence).
• Miravis without Flutriafol in furrow gave 45-47% control of stem canker.
• No sclerotinia infection was identified in the trial.
• Control of phoma leaf spot on lower canopy leaves from seed treatment and 4-6 leaf application was recorded at approximately 37-43% when assessed 6 leaf.
• There was no significant difference in blackleg infection between any of the treatments when assessed at early flowering.
• Overall, for the second year running the use of different fungicide strategies and products has led to large differences in crop canopy appearance but few significant yield increases.
