First report of Meloidogyne marylandi infecting bermudagrass in Oklahoma.
In the autumn of 2013, a stand of ultradwarf bermudagrass (Cynodon dactylon × C. transvaalensis) plants in a sand-based, research putting green in Stillwater, Oklahoma, USA, exhibited symptoms of decline. Roots of the affected plants had small galls and upon staining of the root system, numerous egg masses were evident. The causal pest was identified as Meloidogyne marylandi based on morphological and genetic analyses. This is thought to be the first report of M. marylandi in Oklahoma.
