Wheat in the northern half of Illinois is either already flowering or will be in the next few days. The risk of FHB currently is low for the northern half of Illinois; however, stripe rust is continuing to move northward in the state. Fungicides registered for suppression of FHB that can be applied during the flowering stage of wheat also have efficacy against stripe rust.
