In both experiments observed data revealed that combined applications showed better performance than did single ones. Eggplant growth parameters in terms of fresh shoot and root lengths, and shoot and root weights were remarkably improved with single application of Abamectin or BioNematon followed by plant extracts or vermicompost resulting in a significant (P<0.05) suppression in nematode population in soil and root as well as the number of galls and egg masses. However, the potential of bioagent was increased with the addition of  Moringa leaf powder and significantly (P<0.05) enhanced eggplant growth and suppressed nematode population, root galling and female fecundity even no significant differences were recorded compared to Oxamyl.  Vermicompost derived from municipal wastes showed a low C/N ratio (1:14) with an excess of nitrogen that exhibited nematicidal activity against M.incognita. The addition of vermicompost with such bio-agents showed a synergistic effect upon nematode population, root galling and number of females. Significant differences whether in plant growth or nematode reproduction were not detected compared to Oxamyl. Thus the current study revealed the potential of leaf powder and extractives of Moringa, vermicompost, P.lilacinum and S.avermitilis as safe alternatives to control M.incognita infecting eggplant through an integrated management program and bring sustainability to agriculture.
