Tredway ABSTRACT Spring dead spot (SDS) disease is an important root disease of bermudagrass (Cynodon spp.) in transition zone habitats around the world. Causal agents have been identified in the U.S. as Ophiosphaerella korrae (OK), O. herpotricha (OH), and O. narmari, but they have not been identified in Argentina (ARG). Pure cultures were obtained from symptomatic roots from six different bermudagrass cultivars from 24 different golf courses in SC (a total of 274 samples).
