Fusarium Head Blight Risk Fusarium head blight risk for spring wheat varieties with a rating of 6 or worse will be high across much of the state through the end of the week (Figure 1). The heart of the Red River Valley is the only area with a low to moderate risk. A marked difference in the risk of infection exists between highly susceptible and moderately resistant varieties (Figure 2). Figure 1. Fusarium head blight risk for very susceptible varieties for June 24 through 28. Darker orange indicates moderate risk and red indicates high risk. Figure 2. Fusarium head blight risk for moderately resistant varieties for June 24 through 28. Darker orange indicates moderate risk and red indicates high risk. Other Diseases Last week's scouting reports and my own observations confirmed stripe rust at very low incidence and severity across much of the state (Photo 1). Likewise, bacterial leaf streak, tan spot, and BYDV can also be found, but incidence and severity remain low. Photo 1.
