The alternatives strategies to decrease disease development are those able to destruct a total or partial population density using eco-friendly approach treatments. In this investigation, we demonstrate the symbiotic interaction with <em>Trichoderma koningii</em>, <em>Aspergillus niger </em>and <em>Mucor </em>sp. on the eggplant plants growth and development, and on the defence response induction. The results revealed that the highest fungal frequency from eggplant rhizosphere was registered for <em>A. niger</em>, followed by <em>Mucor</em> sp. and <em>T. koningii</em>. Seeds treatment with <em>T. koningii</em> showed a higher value of length of shoots (2.83 cm), roots (3.00 cm), and leaves (3.50 cm). Obtained results revealed that <em>T. koningii</em> ameliorates the seedling fresh (3.91 g), dry weight (0.24 g), and accelerates plant length (48.67 cm). Obtained results revealed increasing of peroxidase activity (12.53, 12.68, and 11.28 10-1 units.g.mL.min<sup>-1</sup>, respectively) and chlorophyll content (2.11, 1.70, and 1.90 mg.g<sup>-1</sup> fresh weight, respectively) eggplants treated with combination <em>Mucor</em> sp. + <em>A. niger</em> + <em>T. koningii</em>, <em>T. koningii</em> + <em>Mucor</em> sp., and <em>T. koningii</em> alone. To control pathogens fungi within integrated management strategies, the biological control should be taken into consideration.  </p> ER -
