Aims

To develop profitable and sustainable approaches to disease management in HRZ wheat – winter and spring wheat sown 21 April.

Individual objectives specific to the trial were:
- To 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 the number 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

 Fungicide management significantly increased yield in all varieties except RGT Cesario.
 The maximum yield response to fungicides was as follows: RGT Accroc (3.81t/ha) > Revenue 3.39t/ha) > RGT Calabro (2.42t/ha), Anapurna (2.2t/ha), Trojan (1.25t/ha) > Big Red (0.97t/ha) > Scepter (0.91t/ha) and RGT Cesario (0.71t/ha).
 At $300/t the value of even the lowest response to fungicide was $213/ha.
 Anapurna and RGT Cesario both generated 11t/ha but in both cases only two fungicide units was required to achieve these yields, whereas with RGT Accroc it was necessary to use 4 units of fungicide to maximise yield.
 Maximum yield response was achieved with 4 units of fungicide in RGT Calabro, Revenue, Trojan and Big Red.
 With Scepter there was little yield difference (0.14t/ha) between 2 and 4 units of fungicide.
 The impact of fungicide application was noted in grain quality with all fungicide strategies showing lower screenings, although the impact on screenings was clearly related to the size of yield increase, such that with Revenue there was a large difference in screenings (4%) between management approaches and only 1% with RGT Cesario.
