Holcus Leaf Spot
scouted June 12, 2025
- Background
- Corn from Bertie county was scouted and oval tan spots were found irregularly across the field, with a severity of 1%
- Conclusion
- The spots were reported as Holcus leaf spot, a bacterial disease that shows up early in wet, warm conditions. It begins as circular, oval, or irregular dark green, water-soaked spots. As they dry, these lesions turn light tan to white, often with a thin, papery texture, and may develop light brown to reddish margins surrounded by yellow halos. The severity can vary wildly from leaf to leaf.
