Wheat Leaf rust. has been reported and identified by Andy Shirley in commercial wheat fields in Mitchell County and Jason Blankenship in Randolph co. It is early on its arrival, but favorable environmental conditions for leaf rust development are developing or are now in place in the state; therefore wheat field scouting and monitoring should be implemented at this time. If leaf rust is present in your field, this warrants a fungicide application. There are several fungicide options so contact your County Agent to determine what is best for your particular situation.
Triazoles – metconazole (Caramba), propiconazole (Tilt, Propimax), prothioconazole (Proline), prothioconazole + tebuconazole (Prosaro), tebuconazole-containing products (Folicur, others)
Strobilurins – azoxystrobin (Quadris), fluxastrobin (Evito), picoxystrobin (Aproach), pyraclostrobin (Headline)
Mixed mode of action – fluoxapyroxad + pyraclostrobin (Priaxor), flutriafol + fluoxastrobin (Fortix), propiconazole + azoxystrobin (Quilt, QuiltXcel), propiconazole + trifloxystrobin (Stratego), prothioconazole + trifloxystrobin (Stratego YLD), pyraclostrobin + metconazole (Twinline), tebuconazole + trifloxystrobin (Absolute), tebuconazole + azoxystrobin (Custodia)
When leaf rust has become established in a field, triazole fungicides tend to be most effective. Strobilurins have a more preventive activity and tend to be weaker if rust already in the field.
