To assess the impact of using foliar fungicides for controlling leaf disease in Kellalac wheat.
Key messages
A single application of GS39 (flag leaf) of either Opus at 250ml/ha or Amstar Xtra at 100ml/ha to control fungal leaf disease, gave superior yield in Kellalac wheat by comparison to other treatments. There was no significant benefit of applying 2 sprays (GS30 and GS39) compared to a single application at GS39. This was no doubt due to the late onset of disease. The best spray treatment gave and extra 1082 kg/ha of grain compared to the unsprayed control. This gave a net return of approximately $130 per hectare for the best fungicide treatment compared to the control.
In terms of grain quality, screenings were reduced where a fungicide was used.
