Abstract
Plant parasitic nematodes have caused huge yield loss on all agricultural crops. Knowledge of the
type and quantity of these pathogens in soils is an indication of the risk of disease development in
the crops grown on the soils. This study was carried out to determine the plant parasitic nematode
composition of selected agricultural soils in Kwara State, Nigeria. Three sample locations from each
of the forest and savannah agro-ecological zones of the state were selected for the study. Soil
samples were taken from the rhizosphere of five crops commonly grown in each of the six sample
locations (Celosia sp. Cowpea, Maize, Soybean and Teak) using soil auger. Nematodes were
extracted using the modified Bearmann technique and the nematodes were identified using
standard identification key. The identity of the nematodes was confirmed at the International
Institute for Tropical Agriculture (IITA), Ibadan. A total of six nematode genera namely,
Meloidogyne sp., Helicotylenchus sp., Scutellonema sp., Pratylenchus sp., Rotylenchus sp., and
Tylenchus sp. were isolated with Meloidogyne sp. having the highest frequency of occurrence in
most of the sampled locations and crops. The implication of nematodes in agricultural soils is
discussed.
