Mitigating Tar Spot Disease in Nebraska Irrigated Corn
Every year, corn producers and agronomists supporting their operations work to identify and manage diseases. Tar spot disease has moved into eastern Nebraska and will continue to move west, with the potential to cause more than 50% yield loss in susceptible corn hybrids. The fungus-causing tar spot is strongly favored by wet and cool conditions in the corn canopy, potentially worsening disease pressure in pivot-irrigated fields. This project monitors and documents tar spot movement across Nebraska, updates the national distribution map and offers programs to increase local awareness and management needs.
