Spring wheat in SD is now at flowering. However, it has been dry and currently temperatures are low. These conditions do not favor scab development, the reason why the FHB risk tool is showing low risk for FHB throughout SD. For spring wheat just starting to head, there is a need to keep checking on this FHB risk tool until wheat is done flowering. For moderate to high risk for FHB, plan a triazole fungicide at the flowering growth stage to manage FHB.
