This project aims to determine how stubble management strategies and break crops can impact Fusarium crown rot pathogen levels over time. The project is also investigating the potential link between stubble management, subsurface acidity, and Fusarium crown rot in cereals over multiple seasons.

• Predicta B testing across the Riverine Plains during February 2024 showed that 79% of samples collected had medium to high levels of Fusarium crown rot present. 
• A demonstration site sown to wheat for two years (2021-2022), had high levels of Fusarium crown rot — burning the wheat stubble and planting faba beans in 2023 reduced levels to low within a 12 month period.
• Segmented soil tests conducted across Riverine Plains revealed 64% of paddocks tested had pH less than 5 in the 5-10cm layer, with 50 % of the paddocks showing pH below 5 in the 10-15cm layer.
• An acid layer, between 5 and 15cm, can affect production of acid-sensitive crops, as well as nodulation by legume species; if an acid layer is present, the recommended target pH(CaCl) for 0-10 cm is 5.8.
