    abstract = {Laboratory experiments were conducted on the effect of leaf extract of some weeds on root knot nematode, <I>Meloidogyne incognita</I> and also on the chemical compounds in the leaf extract of some weeds. Leaf extracts were obtained from <I>Sida acuta</I> Burm F., <I>Euphorbia hirta</I> Linn<I> Andropogon gayanus</I> Kunth, <I>Phyllanthus amarus</I> Schum and Thomm and <I>Cassia obtusifolia</I> L. weeds. Distilled water and ethanol (95%) were used as the extraction media for nematode bio-assay and phyto-chemical analysis experiments, respectively. Concentrations of each leaf extract of the weed were 5, 10, 15 and 20% (w/v). Approximately, 100 <I>M. incognita</I>  juveniles  were  dispensed  into  each  Petri-dish  containing  the  graded  weed  extracts,  while <I>M. incognita</I> juveniles that were dispensed into distilled water only served as control. Each treatment, including the control, was replicated 10 times. <I>M. incognita</I> juvenile mortality rate increased with an increase in test plant extract concentrations and exposure time. In 15 and 20% (w/v) concentrations of <I>Euphorbia hirta, Phyllanthus amarus </I>and<I> Cassia obtusifolia </I>and 20% (w/v) concentration of <I>Sida acuta </I>and<I> Andropogon gayanus</I>, there was 100% <I> M. incognita</I> juvenile mortality by the 7th day. The result of phyto-chemical analysis revealed that <I>Euphorbia hirta</I> contained tannins, saponins, flavonoids and alkaloids; <I>Andropogon gayanus</I> contained saponins, flavonoids and alkaloids; <I>Cassia obtusifolia</I> contained tannins, flavonoids and alkaloids; <I>Phyllanthus amarus</I> contained tannins, saponins, flavonoids and alkaloids while <I>Sida acuta</I> contained tannins, saponins, flavonoids and sterols chemical compounds.}
