Abstract/Contents:Presents a study initiated during 2008 to determine the responses of bermudagrass and seashore paspalum to the sting nematode (Belonolaimus longicaudatus). Defines two primary objectives of the study: "(1) [to] determine the range of response (resistance or tolerance) of bermudagrass and seashore paspalum cultivars to the sting nematode and identify the best performing cultivars," and "(2) [to] investigate if [whether] a proposed alternative method for assessing sting nematode response is as effective, or more efficient, than traditional methods." Details methods and materials used during the experiment, noting that "nematode population densities in each plot were assayed on the same day the plots were planted. Soil samples were subsequently collected every 90 days after planting." Adds that "turfgrass health was determined by evaluating root lengths and turf density every three months throughout the turf growing season." Reports that "nematodes affected the total root length and turf density of the turfgrass cultivars. A negative linear relationship was found between the population density of B. longicaudatus and the total root length as well as turf density of 'Celebration' bermudagrass." Concludes that "regression analysis indicated that 'Celebration' bermudagrass and 'Aloha' seashore paspalum may be intolerant to B. longicaudatus, while 'Floradwarf', 'Tifgreen', and 'TifEagle' bermudagrasses could be intolerant to H. pseudorobustus."

USGA Summary Points:Bermudagrass is a better host to B. longicaudatus, and seashore paspalum is a better host to H. Pseudorobustus Belonolaimus longicaudatus was a better competitor than H. pseudorobustus in bermudagrass cultivars other than 'TifSport', and H. Pseudorobustus was a better competitor than B. longicaudatus in seashore paspalum cultivars. Population densities of B. longicaudatus were not different among dwarf bermudagrass cultivars, but remained the lowest in 'TifSport' among the non-dwarf cultivars 'TifSport' bermudagrass and 'Sea-Dwarf' seashore paspalum were best for suppression of B. longicaudatus densities in the field. 'Celebration' bermudagrass and 'Aloha' seashore paspalum showed intolerance to B. longicaudatus, and 'Floradwarf', 'Tifgreen', and 'TifEagle' bermudagrasses were intolerant to H. pseudorobustus
