Abstract Botanical extracts of Azadirachta indica, Ocimum canum, Mentha spicata, Aloe barbedenses, Vincia rosea, Tagetes erecta, Calotropis gigantean, Humulus lupulus, Datura innoxia, Rosa damascene and Ricinus comunis were evaluated for their nematicidal effect against Meloidogyne incognita juveniles hatching from egg masses. Results were found that all botanical extracts significantly inhibit/ educe the emergence of juveniles (J2) from egg masses as compared to control. Among the botanical treatments, extracts of Azadirachta indica showed maximum inhibition on the emergence of juveniles from egg masses, maximum effect on larval mortality and minimum gall formation as compared to other plant extracts used.
