Abstract

Key findings • Yield loss from crown rot ranged from 10.5% in the barley variety La Trobe[PBR] up to 61.1% in the bread wheat variety EGA Gregory[PBR]. • Bread wheat variety choice had a large effect on yield where there were high levels of crown rot infection with ten entries being between 0.55 t/ha to 1.18 t/ha higher yielding than EGA Gregory[PBR]. • The barley varieties Commander[PBR] and La Trobe[PBR] and were 1.66 t/ha and 2.37 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 over the use of no seed treatment at planting.
