Abstract

Key findings • Yield loss from crown rot ranged from 6.9% in the bread wheat variety Viking[PBR] up to 31.9% in the durum variety Jandaroi[PBR]. • Bread wheat variety choice had a large effect on yield where there were high levels of crown rot infection with Suntop[PBR], Sunguard[PBR], Beckom[PBR] and Viking[PBR], being between 0.37 t/ha to 0.62 t/ha higher yielding than EGA Gregory[PBR]. • The barley varieties La Trobe[PBR] and Commander[PBR] were 0.62 t/ha and 0.84 t/ha higher yielding than EGA Gregory[PBR] under high levels of crown rot infection, respectively. • Rancona® Dimension did not provide a yield benefit in the presence of high levels of crown rot infection at this site in 2015.
