Starr, J. L., K. L. Ong, M. Huddleston, and Z. A. Handoo. 2007. Control of Meloidogyne marylandi on Bermudagrass. Nematropica 37:43-49. Meloidogyne marylandi is widely distributed on turf in Texas and is frequently associated with poor turf appearance and growth. Suppression of population densities of M. marylandi on established Bermudagrass through application of a new formulation of 1,3-dichloropropene (Curfew), fenamiphos (Nemacur), or the biological agent Paecilomyces lilacinus (MeloCon WG) was tested in separate experiments. Application of the fumigant 1,3-dichloropropene effectively suppressed nematode population densities for 10 weeks with a slight improvement in turf color (P = 0.08). Neither P. lilacinus nor fenamiphos effectively suppressed nematode population densities nor improved turf appearance. Fenamiphos did reduce root galling (P = 0.05) in one of two experiments. Juveniles of M. marylandi encumbered with Pasteuria spp. endospores were observed during these studies and the efficacy of this biological control agent in established turf needs to be investigated.
