#Wheat Disease Update

Questions have been rolling in regarding dead leaves in the mid to lower wheat canopy.  Wheat is heading in much of South Central Nebraska and in some cases has begun to flower.  When considering a fungicide application, once your wheat has begun to flower, there are only certain products that are labeled for use.  These include but are not limited to fungicides such as Proline, Folicur, and Prosaro.  All of these have a 30 day pre-harvest restriction and can only be applied up to 50% flowering.  For more information on all fungicides, rates, and pre-harvest restrictions for wheat, please check out this resource from Dr. Stephen Wegulo, UNL Extension Wheat Pathologist.  Below is a short video of me scouting a wheat field so you know what to look for in your fields.  Fungicides will not help leaves affected with barley yellow dwarf as that’s caused by a virus; however, with the amount of stripe rust in our canopies and seeing it on the flag leaves already in addition to the rain and humidity allowing for increased risk of Fusarium Head Blight (scab), I still feel a fungicide is a good option.
