The 2023 HYC Barley Disease Management trial looked to investigate the (i) influence of management strategies on grain yield and,  (ii) Influence of fungicide treatment on Net Form of Net Blotch (NFNB) severity and incidence on Flag, Flag-1 and Flag-2, and on green leaf retention 

• Trials conducted between 2020 and 2023 in Hagley have not shown any response to fungicide in spring sown barley.
• These results suggest that the management needed to combat barley disease in a susceptible variety when autumn sown, are not required in a spring sown scenario where pressure is much lower.
• Although there were statistical differences in the Net Form Net Blotch (NFNB) disease assessment conducted at early grain fill, levels of disease were minimal with severity levels under 5% leaf area infected and less than 1% incidence on Flag-1 (Table 2).
• Fungicides had no influence on grain quality.
