Abstract : The indigenous egg parasitic fungal isolates, Engyodontium aranearum was evaluated for its nematicidal
potential against root knot nematode, Meloidogyne incognita. The study revealed 53.75 per cent egg parasitization by the fungal isolate.
Fungal colonies grew over the eggs and fungal hyphae penetrated the egg shells resulting in rupturing of egg shell layers,
enzymatic digestion and empty eggs. The fungal culture filtrate was found to inhibit egg hatching by 83.42 per cent and
caused upto 91.36 per cent juvenile mortality. This isolate also reduced the attraction of infective juveniles towards tomato
root by 79.29 per cent. It seems to be a first report on the antinemic property of the fungus E. aranearum against root
knot nematode, M. incognita and its effect was found comparable with Paecilomyces lilacinus which is known as an efficient
nematode egg parasitic fungus.
