This experiment was conducted in the laboratory of the Department of Crop Production of the Federal University of Technology Minna to evaluate the inhibitory effect of Azadirachta indica and Moringa oleifera leaf extracts at different level of concentrations S (100 %), S/2 (50 %), S/10 (10 %), S/100 (1 %) on egg hatch of Meloidogyne incognita. The experiments were laid out in a completely randomized design (CRD) and replicated four times. All the concentrations of Moringa oleifera and Azadirachta indica and their various combinations inhibited egg hatch of Meloidogyne incognita throughout the period of observation with the standard solution. As the egg masses were exposed to these concentrations and the larvae hatched were recorded at time intervals of 3, 6, 12, 24, 48, 72 and 96 hours respectively. It was observed that the standard solution (S) of the leaf of both extracts significantly (p ≤ 0.05) inhibited egg hatch of Meloidogyne incognita in which the S, S/2, S/10 inhibited egg hatch of this parasite compared to S/100 and the control (distilled water) in which high number of larvae of 50, 137 and 75, 133 in A. indica and M. oleifera, respectively.
