Item Bioactivity of Aqueous Extract of Vernonia amygdalina and Peperomia pellucida on Meloidogyne incognita infecting two Telfairia Accessions(2021) Apalowo, O. A; Izuogu, N. B; Baba, H. S; Mustapha, S.Pot and field trials were conducted at the Teaching and Research farm of University of Ilorin, Nigeria to determine the efficacy of aqueous extracts of Vernonia amygdalina and Peperomia pellucida in the management of Root-knot nematode, Meloidogyne incognita infecting two accessions of Telfairia occidentalis Hook. F. Pots were inoculated with galled roots of Celosia agentea one week before planting to increase the initial nematode population. The pot trial was set up in a Completely Randomized Design with five replicates while the layout for the field experiment was a Randomized Complete Block Design replicated four times. Transplanted twoweek old seedlings in the pots were inoculated with 10g of infected Celosia galled root before application of treatment whereas the field was naturally infected. Treatment was applied a week after transplanting and repeated six weeks after transplanting. Results from the study revealed that treated plants in both trials had significantly higher number of branches, vine length and number of pods. Also, the population density and galling of roots were significantly reduced in treated plots to 3 and 4 against the control which has a gall rating of 7 and 6 respectively in pot and field. While the improved yield and reduction in nematode population could be traced to the treatments used, the tolerance of the accessions cannot be discountenanced.Item Nematicidal activities of aqueous extracts of Moringa oleifera leaf and seed on Root-knot nematode, Meloidogyne incognita infecting cucumber(Nigeria Society of Nematologists (NISON), 2016) Olajide, M.

RItem Plant Parasitic Nematodes Associated with Selected Agricultural Soils in Kwara State, Nigeria.(Faculty of Agriculture, University of Ilorin, Nigeria., 2020) Ahmed, O.; Izuogu, N. B; Baba, H. S; Kalejaiye, N. APlant 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.
