Regional crown rot management – Trangie locations
Aims

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 affect on their relative yield in the presence of this disease.

This experiment was one of 11 conducted by NSW DPI in 2016 across central/northern NSW extending into southern Qld; to examine the effects from crown rot on the yield and quality of four barley, three durum and 13 bread wheat varieties.

Key messages

Key findings

• Yield loss from crown rot ranged from not significant in the bread wheat variety LRPB ReliantA up to 16.9% in the barley variety CompassA

 • Bread wheat variety choice affected yield in the presence of high levels of crown rot infection with three entries being between 0.45 t/ha and 0.85 t/ha higher yielding than the susceptible bread wheat variety EGA GregoryA.

• Grain protein levels were low across the site (mean of 9.8%) and varied from 8.7% in MitchA up to 10.6% in LRPB SpitfireA Crown rot infection did not affect protein levels in any entry.

• Crown rot infection caused a small (1–4%), but significant increase in screenings in the barley variety La TrobeA and all of the 13 bread wheat entries.

Plot size Not specified
Plot replication Not specified
Fertiliser

80 kg/ha Granulock Z Extra (Sapphire) (11.5% N 19.8% P 5.4% S) at sowing.

Inoculant Pathogen treatment: Added or no added crown rot at sowing using sterilised durum grain colonised by at least five different isolates of Fp at a rate of 2.0 g/m of row at sowing.
Other trial notes

Starting soil water: ~60–70 mm plant available soil water (based on a 25% fallow efficiency) (0–120 cm)

Varieties (20)

• Four barley varieties: CommanderA, CompassA, La TrobeA and SpartacusA.

• Three durum varieties: JandaroiA and LillaroiA plus the numbered line 190873.

• Thirteen bread wheat varieties: EGA GregoryA, LRPB FlankerA, BeckomA, CoolahA, SunmateA, LRPB LancerA, LRPB ReliantA, LRPB GauntletA, LRPB SpitfireA, MitchA, SuntopA and SunguardA; (listed in order of increasing resistance to crown rot) plus one numbered line LPB12-0494.

Conclusions:

Three of the bread wheat varieties (MitchA, CoolahA and BeckomA) provided a 10–19% yield benefit over growing the susceptible bread wheat variety EGA GregoryA under high levels of crown rot infection at Trangie 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.
