Meloidogyne species cause root knot in Barley, Brinjal, Wheat, Rice, Banana etc. which can be managed by chemical and

non chemical methods. The use of pesticides including nematicides has become very popular for control of pests. Isolation

of nematophagous fungi for isolation of nematophagous fungi from different substrates viz., leaf litter, composts, farm yard

manure (FYM) and decaying root galls, water agar, maize meal agar (MMA) and rabbit dung agar media were used.

100gm of soil sample were collected in separate polythene bag from top profile of soil from different location. The growths

of plant were considerably reduced after inoculation of mass culture of A. oligospora even in combination with FYM.

However, root wt of the plants treated with mass culture of A. oligospora increased maximum being in A. oligospora +

FYM. It was interesting to know that in spite of suppressive effect on plant growth the root galls were significantly reduced

in plant with A. oligospora + FYM. From the observation it is evident that the A. oligospora control root knot nematode.
