Two predacious fungi, Arthrobotrys oligospora and Dactylaria brochopaga, were mass cultured on splitted sorghum seed, wheat bran + wheat straw, wheat bran + wheat straw + 2% jaggery solution and splitted maize seed. All the substrates supported excellent growth of A. oligospora. For D. brochopaga, splitted maize supported fair growth. Both the fungi, when applied in plots, significantly reduced the number of root knots of tomato in sterilized and unsteilized soils. D. brochopaga was superior to A. oligospora in reducing incidence of root knot nematode on tomato in unsterilized soil.
