ABSTRACT The root knot nematode species (Meloidogyne incognita) is a devastating pest in the tropical and sub-tropical regions, and is known to infect a wide variety of crops, leading to economic damage to these crops. The objective of this laboratory experiment was to investigate egg hatch of M. incognita exposed to aqueous root and leaf extracts of the African marigold (Tagetes erecta), Moringa (Moringa oleifera), and (Gboma) Solanum marcrocarpon plants at five (5) ..concentrations (0%, 10%,25%,50% and 100%). The research employed a 3 x 2 x 5 factorial experiment laid out in a completely randomized design (CRD), with thirty (30) treatment combinations replicated three times. Significant differences existed among the treatments for leaf and root extracts on egg hatch of the root knot nematode. Generally, inhibition of egg hatch was enhanced at all aqueous concentrations regardless of plant species or plant part utilized, compared to the control (0%). Suppression of egg hatch increased gradually with increase in the extract concentrations, with the concentrations at 100% giving the lowest mean egg hatch values. Moringa root extract at 100% concentration had the lowest mean egg hatch value of (5) while the 100% S. Macrocarpon leaf extract concentration had the highest mean egg hatch values (24).
