Wheat fields in Kentucky are now at anthesis (Feekes 10.51) or fast approaching it. Currently, most of the state is under “low risk” for FHB for susceptible to moderately resistant varieties; however, for very susceptible varieties, some areas are in a medium to high risk, with predictions of risk to increase over the next two days. For in-season management of FHB, it is important to apply a fungicide with efficacy against FHB. The most recent edition of the “Fungicide Efficacy for Control of Wheat Diseases” publication is available on the Crop Protection Network (https://cropprotectionnetwork.org/publications/fungicide-efficacy-for-c…), which provides information on efficacy of fungicides for control of FHB and other diseases. For FHB management with fungicides, it is important to apply at Feekes growth stage 10.51 up to about 6 days after for the greatest protection against FHB.
