Wheat fields in Kansas are at or approaching flowering in southeast and south-central counties. The weather is currently highly favorable for FHB (scab) development in these parts of the state. It will be critical to carefully watch fields that are approaching the application window for a scab fungicide (Flowering, Feekes 10.5.1). The highest risk will be in fields of scab-susceptible varieties that are planted back into corn residue. For a reminder about the scab ratings for individual varieties, please refer to the Kansas Wheat Variety Guide: https://bookstore.ksre.ksu.edu/pubs/mf991.pdf.
