Two full-season microplot experiments were conducted to evaluate the damage potential of a plant-parasitic nematode community on St. Augustine and centipede turfgrasses grown in three soil types and to assess the influence of soil type on reproduction of the nematode populations comprising the community. Genera of nematodes associated with both turfgrasses included Criconemella, Helicotylenchus, Meloidogyne, Pratylenchus, Tylenchorynchus, and Tylenchus spp. In 2012, nematodes did not cause significant damage to either turfgrass, but soil type affected plant growth parameters. In 2013, there was significant nematode-related injury to both turfgrasses, but there were no significant effects of soil type on plant growth parameters.
