Abstract/Contents:"Work was conducted at Stillwater, OK during 1997-1999 to determine the resistance of two African bermudagrasses (Cynodon transvaalensis), OKCt2747 and OKCt2567, as well as Tifway bermudagrass (C. dactylon x C. transvaalensis) to spring dead spot (SDS) caused by Ophiosphaerella herpotricha (OH). Turf was regularly mowed to 6 mm, fertilized with 195 kg N ha-1 yr-1 and watered as needed. Grasses were inoculated with OH isolate KS 188 in Sept. 1996 and SDS patch area was recorded in late April/early May of each yr. Mean patch diameter increased each yr with areas of 29, 288, and 833 square cm recorded in 1997, 1998 and 1999, respectively. No significant differences in patch area were present among cultivars in 1997 and 1999 although Tifway had numerically larger patch areas in both of these years. In 1998, patch size was significantly larger on Tifway than on OKCt2747 and OKCt2567. The 3 year overall mean patch sizes in square cm were 692 for Tifway, 345 for OKCt2747, and 112 for OKCt2567 (lsd=200 square cm). While African bermudagrasses appear to be susceptible to SDS caused by OH, the specific cultivars tested in this trial to be more resistant to the disease than Tifway."
