Abstract/Contents:"We studied the influence of entomopathogenic nematodes, Steinernema carpocapsae and S. riobravis, on natural populations of plant-parasitic nematodes (PPNs) infesting turfgrass in Georgia and South Carolina. S. riobravis applied at 6 × 10⁹ infective juveniles (IJs)/acre provided up to 95-100% control of the root-knot, Meloidogyne sp., sting, Belonolaimus longicaudatus, and ring nematode, Criconemella sp., in Georgia, but S. carpocapsae had no effect. S. riobravis was as effective as the chemical nematicide, Fenamiphos (Nemacur 10G) at 4 weeks after treatment and more effective at 8 weeks after treatment. In South Carolina, both S. riobravis and S. carpocapsae applied at 1 × 10⁹ IJs/acre provided up to 86-100% control of the root-knot, sting and ring nematodes. Application of 6 × 10⁹ Js/acre increased control by only 4-14% over the 1 × 10⁹ dosage. Possible causes of differences in efficacy of S. carpocapsae at the two sites are discussed. It is concluded that ^DS. riobravis may provide effective, predictable and economical control of PPNs in turfgrass.
