Abstract
The 2015 growing season was cooler and wetter than normal. Several foliar diseases were prevalent including northern corn leaf blight, eyespot, southern rust, Goss’s leaf blight, and Physoderma brown spot. Towards the end of the season, stalk quality was poor across the whole state and standability issues occurred. The most prevalent stalk rot was anthracnose, but Physoderma stalk rot, Gibberella and Fusarium stalk rot were reported.
