Abstract: A systematic zig-zag design was implemented at three anthurium shade-houses during 1992 - 1993 for monthly sampling of plant - parasitic nematodes. Radopholus similis was shown to be the predominant nematode associated with the crop. Paratylenclus minutus was the only other potential plant - parasitic nematode identified. Population densities of R. similis exhibited annual fluctuations with maximum levels observed between August and September at the three locations. The population densities of nematodes varied widely with locations but the composition of females, males, and juveniles within the populations was similar. Various fungi were isolated from root lesions. Stunting, chlorosis, and root rotting were commonly associated with nematode infested plants.
