So far this spring, overall disease activity in wheat across much of Alabama has been light. Neither leaf or yellow rust has been observed in any of the cultivar trials located around the state, while light Septoria leaf spot was diagnosed in wheat cultivar screening trials in North AL. Scab risk is high over SW AL but medium to low across the rest of the state. Most likely, much of the wheat in that area has already flowers and is at low risk for scab development. Wheat in Central and North AL is flowering now.
