Tar Spot of Corn: Fungicide Management provides Virginia corn producers and crop advisors with practical, research-based guidance for identifying and managing tar spot, an emerging foliar disease caused by Phyllachora maydis. The publication explains disease biology, environmental conditions that favor development, and the potential impacts on yield, grain quality, and harvestability. It outlines integrated management strategies with an emphasis on fungicide product selection, application timing, return-on-investment considerations, and the use of Crop Protection Network decision-support tools to improve disease management decisions under Virginia and Mid-Atlantic growing conditions.
