A few new fungicide combinations are now labeled for sweet corn as well as field corn. Stratego YLD is a new combination of trifloxystrobin plus Proline (prothioconazole). Headline AMP is a combination of pyraclostrobin and Caramba (metconazole) and Quilt Xcel is a higher concentration of Quadris (azoxystrobin) plus Tilt (propiconazole). They will provide excellent control of Northern corn leaf blight, gray leaf spot, and rust if used as directed on the label.
