| Abstract | ||||
Aqueous extracts of Zingiber officinale (Leaves), Salvadora persica (Leaves and stem), Moringa oleifera (Leaves), and Origanum vulgare (Leaves), at three concentrations (S, S/2, S/4) were assessed on egg hatching and juvenile mortality of the root knot nematode, Meloidogyne incognita in vitro. Data were recorded after 12, 24, 48 and 72 hours of application. Results showed that, some of the tested extracts significantly (p =0.05) inhibited egg hatching and increased juvenile mortality as compared to check treatment. The result noted that, the highest reduction in egg hatched and hatching inhibition percentage recorded with Salvadora persica leaves and in juveniles mortality and reduction mortality percentages were (17 and 58.53 %) (136 and 90.67%), respectively. | ||||
