Key Messages

• Mean grain yield of PBA Hurricane XT was 0.45 t/ha at Pinnaroo, 2018.
• No difference in grain yield was observed between herbicide treatments (P=0.773). Interactions between herbicide and application rate also had no observable differences for grain yield (P=0.97).
• There were observed differences for biomass yield between herbicide treatments (P=0.037).
• Diuron treatments had the highest biomass yield of 2.03 t/ha.
• Metribuzin and Terbuthylazine treatments resulted in a 14 % reduction in biomass yield, compared to Diuron.
