Wheat growers in western PA should watch their crops closely for heading and flowering moving into the weekend, when very susceptible varieties will be at high risk for scab infection. If you choose to spray, target your wheat crop at early flowering. Caramba, Prosaro and Miravis Ace give good control of most leaf and head diseases, in addition to suppressing scab. Spray nozzles should be angled at 30° down from horizontal, toward the grain heads, using forward- and backward mounted nozzles or nozzles with a two directional spray, such as Twinjet nozzles.
