Aims

This research was initiated to provide preliminary data to improve our understanding of:
• The effectiveness of timing of fungicide application for eyespot management in the South East.
• Interactions between MS and S varieties and fungicide efficacy.
• Impact of fungicides, varieties and combinations on eyespot inoculum carryover.

Key messages

• This is the first quantitative information we have for the effects of varietal resistance and fungicide application and timing on eyespot expression and crop yield in the South East. These preliminary recommendations will become more robust as we gather more information.
• No fungicides are registered at present for eyespot management, but it is anticipated at least one registered product will be available for use in the 2017 season. Applying fungicides for eyespot management reduced eyespot expression and increased yields in the trials at Kangaroo Inn.
• Select more resistant varieties – untreated they will perform better and they may also be more responsive to fungicide application, particularly where disease pressure is high.
• Delays in fungicide application until after early stem elongation (recommended timing, as the canopy is still open enough to allow good coverage of the stem bases) may reduce eyespot incidence and severity but may not give a yield response.
