In the present study an attempt has been made to control the root knot nematode through the combination of two fungal bioagents, Aspergillus fumigatus and Trichoderma harzianum, both collected from eggmasses of root knot infected brinjal plants. The larvicidal, ovicidal and egg parasitisation capacity tests were conducted for both fungi by allowing fresh eggmasses into the fungal mat. The results indicated a significantly remarkable reduction in Meloidogyne incognita population in the treatment where both the bioagents were used. It is attributed that in this dual treatment the toxic effect of A. fumigatus killed a good number of infective juveniles in the rhizosphere while T. harzianum parasitzed the eggs inside the eggmasses resulting in very poor nematode population. Such integration of toxic and opportunistic fungi would prove better as compared to when either of them is used alone.
