Abstract:
Root knot nematodes, particularly Meloidogyne incognita, pose a significant threat to global agriculture, causing extensive damage to various crops and leading to substantial economic losses. Chemical nematicides have raised environmental concerns, alternative strategies that are eco-friendly and sustainable are the need for the hour. This study aimed to investigate the potential of crude extract derived from Xenorhabdus nematophila (MK977604) a symbiotic bacterium associated with entomopathogenic nematodes Steinernema carpocapsae (MK977607), for the management of M. incognita. Crude extracts at X. nematophila at 1.5% concentration significantly inhibit egg mass hatching (no hatching) and juvenile mortality (95.10). The present research revealed that X. nematophila exhibits nematicidal properties and can suppress the population of root knot nematodes at lower concentration under in vitro study.
