Most of the winter wheat in the state is at flowering or will soon be flowering. A fungicide application is usually done at this wheat growth stage to control Fusarium head blight (FHB) or scab. However, based on the FHB prediction tool, the risk for FHB is low throughout the state (Figure 1) and a fungicide application is not advised. FHB is promoted by wet and warm weather and for the most parts of the state, it has been dry, hence the reason for low risk for this disease. Growers are encouraged to keep checking on FHB prediction tool until wheat is done flowering to determine the need for applying a fungicide to manage FHB.
