Aims

To develop profitable and sustainable approaches to disease management in HRZ wheat.

Individual objectives specific to the trial were:
- Monitor the effectiveness of flutriafol in furrow for early disease control in wheat.
- To evaluate whether newer germplasm or new fungicide chemistry allows a reduction in thenumber of fungicide applications whilst increasing profitability (note: reducing the number of fungicides is seen as a key measure for slowing down resistance development in cropping systems).
- Examine whether there is germplasm (varieties tested) that has sufficient early season disease resistance to replace the need for the Timing 1 (T1) spray applied at GS31-32.
- To determine the cost benefit ratio of fungicide application in HRZ regions of different season lengths.

Key messages

 Yields were severely curtailed by waterlogging in this trial but results mirror what was observed in disease levels at other HYC research sites.
 Waterlogging compressed the yield impact of fungicide application, but the influence of genetic resistance was still apparent in the results.
 As observed at other centres Revenue gave a significantly greater response (maximum 2.61t/ha) to a disease management package than the higher yielding cultivars such as RGT Cesario and Anapurna where the maximum response to fungicide was 0.51t/ha and 0.55t/ha respectively.
 These larger responses to fungicides were the result of higher infection levels of Septoria tritici blotch (STB) and late leaf rust infection which were far less significant in Cesario and Big Red.
 The other aspect of the yield results that is more noticeable is that with the more disease resistant lines there is much less difference in whether it was 1, 2 or 4 units of fungicide.
