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

Fig. 15. Mortality of bermudagrass infected with O. herpotricha was monitored by collecting cores of infested turf periodically during the winter and placing in the greenhouse to induce regrowth. In 2004-2005, mortality increased rapidly during December and January and then plateaued. In contrast, mortality increased gradually throughout the sampling period in 2005-2006.
