Winter overseeding of an established stand of 'Tifgreen' bermudagrass (Cynodon magenissi) with perennial ryegrass (Lolium perenne cv. CBS2) resulted in significant increases in the visual rating scores and ash root dry weights when compared with non-overseeded control plots. No significant effects were observed on population density estimates of Belonolaimus longicaudatus, Hoplolaimus galeatus, Criconemella ornata, or Meloidogyne spp. from overseeding throughout the 88-day study. A 2 x 2 factorial experiment evaluating the effects of lowering the mowing height of 'Tifgreen' bermudagrass from 1.30 to 0.65 cm and (or) fenamiphos application (22.4 kg a.i./ha broadcast) showed significant changes in the visual rating scores of the turfgrass 42 days after the treatments. A significant decline in the density of B. longicaudatus and an increase in turfgrass quality were associated with the nematicide treatment. Vertical distribution of phytoparasitic nematodes in the soil profile were exami
