To develop profitable and sustainable approaches to disease management in HRZ barley.
• Levels of Net Form Net Blotch (NFNB) and Spot Form Net Blotch (SFNB) were elevated in 2022 compared to previous years, producing a high amount of disease pressure, particularly in RGT Planet.
• Fungicide management had a significant effect on yield with a more robust program, including a seed treatment and three applications throughout the season, producing a significantly higher yield, approximately 0.42 t/ha above the average (Table 1).
• Although not reflected entirely in the yield, the untreated plots showed higher levels of NFNB and SFNB throughout the entire growing season, with a lower green leaf retention (GLR) (Table 3).
• In general, more complex fungicide programs returned a higher NDVI value throughout the season when compared to the control, indicating a healthier and greener plant (values not shown).
