Abstract/Contents: | "Spring dead spot (SDS), caused by O. herpotricha, is the most damaging disease of bermudagrass (Cynodon dactylon L.) in Oklahoma. The objective of this study was to evaluate the viability of dormant bermudagrass in patches affected by spring dead spot caused by O. herpotricha. Soil cores (6-cm diam. × 10 cm deep) containing dormant bermudagrass were collected monthly over winter (Dec, Jan, Feb, and March of 2004-2005 and 2005-2006) from six different spring dead spot patches and from dormant grass known to not be affected by spring dead spot. Cores were transplanted into pots containing a soil mix and placed in a greenhouse. The number of live bermudagrass shoots that emerged in each pot was determined 2-3 weeks after placement in the greenhouse. In December 2004, a 58 percent mortality rate was observed compared to 22 percent in December 2005. However, the reduction in plant viability was similar by March with an 89 and 81 percent reduction in 2005 and 2006, respectively. The results of this study suggest that spring dead spot of bermudagrass can cause death of dormant plants throughout winter in Oklahoma." |
