Abstract/Contents: | "Spring dead spot (SDS) disease of bermudagrass primarily is caused by Ophiosphaerella herpotricha in the southern Great Plains and by O. korrae in the southeastern United States. We studied the aggressiveness of these fungi to selected bermudagrass cultivars following cold temperature treatments. One susceptible (Tifgreen), two resistant (Midlawn, Guymon) and one cultivar (Champion) with undetermined field resistance to SDS were inoculated with O. herpotricha or O. korrae isolates. Inoculated grass was incubated at 25°C (non-acclimated) or 4°C (cold-acclimated) for 1 mo and then exposed to -2 to -8°C for 2 to 8 hr. Shoot survival was determined 1 mo after exposure to subfreezing temperatures. Inoculated, cold-acclimated plants exhibited greater shoot mortality than similarly treated non-acclimated plants. In cold acclimated plants, O. herpotricha caused more shoot death than O. korrae at all freezing temperatures tested. No differences in shoot mortality were detected among cultivars inoculated with the same pathogen. In general, shoot mortality on inoculated, non-acclimated plants was relatively light and was not affected by lowering the freezing temperature from -2 to -6°C. O. korrae caused similar or more shoot death that O. herpotricha on all non-acclimated cultivars." |
