To develop profitable and sustainable approaches to disease management in HRZ barley.
• A wetter than average spring, high inoculum in the environment and the use of susceptible varieties, NFNB pressure was extremely high in 2022.
• The use of SDHI chemistry at the second spray timing was most effective at reducing NFNB severity on flag-1, the most important yield contributing leaf in barley.
• There was no yield difference between the single spray programs and the untreated, suggesting this level of management is not appropriate for high disease pressure environments.
• There were no significant improvements in yield between the 4 fungicide units, 3 fungicide units or 2 fungicide units regardless of seed treatment/foliar spray combinations.
• The cheaper fungicide managements (untreated and single sprays) gave poorer screening and retention figures as well as increased brackling when assessed at crop maturity.
