Crown rot (CR), caused predominantly by the fungus Fusarium pseudograminearum (Fp), remains a major constraint to winter cereal production in the northern grains region. Cereal varieties differ in their resistance to crown rot, which can have a significant effect on their relative yield when the disease is present.
This experiment was one of 11 conducted by NSW DPI in 2016 across central/northern NSW extending into southern Qld; to examine how crown rot affects the yield and quality of four barley, three durum and 13 bread wheat varieties.
CONCLUSIONS:
Cereal crop and variety choice affected yield in the absence and presence of added crown rot inoculum, which differed by 1.41 t/ha and 1.30 t/ha, respectively between the best and worst entries. Only the bread wheat variety BeckomA provided a yield benefit (15%) over growing the susceptible bread wheat variety EGA GregoryA under high levels of crown rot infection at Merriwa in 2016. This could have maximised profit in this growing season, but will not reduce inoculum levels for subsequent crops because all winter cereal varieties are susceptible to crown rot infection. Winter cereal crop and variety choice is therefore not the sole solution to crown rot, but rather just one element of an integrated management strategy to limit losses from this disease.
