To develop profitable and sustainable approaches to disease management in HRZ barley.
There was no significant response to fungicide for grain yield or grain quality from spring sowing (table 1 and table 2).
Disease levels were low, but despite up to 20% of the leaf area affected with net form of net blotch and scald there was no yield response (figure 1).
Spring sown barley is incredibly robust, the canopy develops rapidly and disease develops later and has less impact on grain yield.
This is a similar finding to 2020, and demonstrates intensive fungicide inputs, and more expensive SDHI chemistries may not be required to the same degree as autumn sown systems (see Millicent results 2021).

Spring sown barley summary: The key feature of the Tasmania HYC Barley site is the fact it is spring sown and supplemented with irrigation. This presents different challenges to growing barley such as a greater chance of heat risk during grain fill, and brackling from rapid growth during stem extension. Cultivars that are less responsive to longer days (photoperiod) are also required to ensure they do not develop too early and build insufficient biomass. |
