Description The distribution of plant parasitic nematodes in different agroecological zones representing the major pigeonpea-producing regions in northeastern Kenya was studied in January 1992. Forty two nematode species belonging to 25 genera were associated with pigeonpea in these regions. Aphelenchus avenae and Ditylenchus spp. were frequently detected. Scutellonema unum, Meloidogyne javanica and Rotylenchulus parvus were potentially important species associated with pigeonpea; S. unum was detected in 44% of the samples, M. javanica in 40%, and R. parvus in 37%. Incidence of the root-knot disease caused by Meloidogyne spp. was 19.5%. Crop growth was stunted and patchy in many of the root-knot nematode infested fields. All the nematode species except Meloidogyne sp. have been reported for the first time in association with pigeonpea in Kenya., 16 ref., The distribution of plant parasitic nematodes in different agroecological zones representing the major pigeonpea-producing regions in northeastern Kenya was studied in January 1992.
