ABSTRACT:

Five garden egg fields (monoculture) were visited within Obio-Akpor LGA during 2007-08 seasons. Root and soil samples were collected and processed to identify and estimate the population levels of plant-parasitic nematodes associated with garden egg in the area. The predominant genera in the soils in terms of frequency of occurrence are Meloidogyne spp., (31%), Pratylenchus spp. (20.3%), Helicotylenchus spp.,(18.6%), Scutellonem spp., (9.7%), Radopholus spp., (4.4%), Tylenchulusspp., (4.4%) and others (11.6%) such as Aphelenchoides spp., Trichodorus spp., Aphelenchus spp., and Xiphinema spp. The roots contain Meloidogyne spp., (34.9%), Pratylenchus spp., (24.5%),Helicotylenchus spp., (14.2%), Scutellonema spp., (8.5%), Radopholus spp., (4.7%),Aphelenchoides spp., (3.8%), Tylenchulus spp., (2.8%) and others (6.6%). The results of the survey showed that root-knot nematodes might be the major plant parasitic nematode of garden egg in this area and need to be managed
