We have started to receive questions and initial reports regarding the need to spray foliar fungicides in corn and soybean.

A recent survey of our winter wheat variety trials found Fusarium Head Blight (FHB) or Head Scab at all four of our variety testing locations: Janesville, Arlington, Lancaster, and Chilton. At these locations, both incidence and severity are relatively low. At our most uniform and prevalent FHB site (Lancaster) our ratings show an FHB index range from 0.6 to 8.8 among the varieties.

Wheat head scab (synonym, wheat head blight), caused by several species of Fusarium, but in the U.S., mainly Fusarium graminearum, was noted in a routine survey of the winter wheat variety trials during the week of June 16th (Figure 1). This was not an unexpected discovery given the recent weather conditions during the flowering period.
