To develop profitable and sustainable approaches to disease management in High Rainfall Zone (HRZ) wheat.
• In low yielding trials all fungicide treatments were significantly higher yielding than the untreated, however there were no significant differences between the different strategies based on 1 spray, 2 sprays or 4 units of fungicide.
• In line with previous seasons Big Red was relatively disease resistant to Septoria tritici blotch (STB) and did not suffer from the new strain of stripe rust to the same extent as RGT Cesario.
• Therefore, going forward at present, one – two units of fungicide should be sufficient to combat STB susceptibility in 2023 as these were the most cost-effective control programmes under very high disease pressure in 2022.
• There were no significant differences in grain quality as a result of fungicide treatment.
