Managing Early Onset of Foliar Diseases in Corn

By agKnowledge Spotlight-Dekalb

• Environmental conditions have promoted early infections of foliar diseases in corn. Early Northern corn leaf blight infections to pre-tasseling corn may reduce yield potential if favorable conditions for the disease continue.
• Begin scouting fields prior to tasseling to assess disease severity.
• Fungicide applications may be warranted in fields with a history of disease, corn residue, and high disease severity.
