A survey was conducted to provide baseline information on nematodes associated with prevalent weed species in Makurdi located in the Southern Guinea agro-ecological zone of Nigeria. 30 common weed species belonging to 28 genera representing 15 weed families were collected from four different locations in Makurdi and examined for the presence of nematodes in their root and rhizosphere. A total of 43 nematode genera representing 22 families were detected in 93.33% of rhizosphere samples. 100% occurrences of free-living nematodes (FLN), 75% occurrence of plant-parasitic nematodes (PPN) and 1% occurrence of entomopathogenic nematodes (EPN) were recovered.
