Spring dead spot is a destructive disease of bermudagrass turf in climates where the host is exposed to freezing temperatures during winter dormancy. The disease is the result of a complex interaction between a dormant host plant, fungal pathogens in the genus Ophiosphaerella, and environmental conditions. Although progress has been made in our understanding of the individual factors that determine spring dead spot development, we must begin to understand how factors interact to influence the disease. This knowledge will facilitate the development of effective and integrated management plans for spring dead spot in bermudagrass turf.
