Spring Dead Spot of Bermudagrass: A Challenge for Researchers and Turfgrass Managers

Fig. 18. As previously found in the midwestern United States, O. herpotricha is more virulent than O. korrae in North Carolina as well. Nineteen months after inoculation, 98% of O. herpotricha inoculations induced spring dead spot symptoms, and patches averaged 22 cm in diameter (three patches on right), whereas 60% of O. korrae inoculations induced spring dead spot symptoms, and patches averaged 9.4 cm in diameter (three patches on left).
