Today in a wheat field I stumbled upon some wheat leaf rust. It threw me off for a bit considering it’s early for the disease to be in the field! This disease is the one of most concern in wheat production. If it is found in the field then a fungicide spray will be warranted! This disease can spread rapidly and cause extensive damage within a short time.
Wheat leaf rust, caused by the fungus Puccinia triticina (formerly known as Puccinia recondita f. sp. tritici), is often a destructive foliar disease of wheat in the state of Georgia.
If leaf rust is present in your field this warrants a fungicide application, the options are:
propiconazole (Tilt, Propimax)
prothioconazole + tebuconazole (Prosaro)
tebuconazole-containing products (Folicur, others)
Mixed mode of action
fluoxapyroxad + pyraclostrobin (Priaxor)
propiconazole + azoxystrobin (Quilt, QuiltXcel)
propiconazole + trifloxystrobin (Stratego)
prothioconazole + trifloxystrobin (Stratego YLD)
pyraclostrobin + metconazole (Twinline)
tebuconazole + trifloxystrobin (Absolute)
