Studies were conducted in a greenhouse to assess the role of organic amendments, Trichoderma viride Pers. ex Fr. and carbofuran in the population of nematode trapping fungus. Arthrobotrys cladodes var. macroides (Drechsler, 1944) and plant parasitic nematodes and their interaction on growth of tomato. Application of organic amendments enhanced the population of the nematophagous fungus. Increase in density of the nematode trapping fungus, A. cladodes var. macroides was highest in a loamy soil ameliorated with 2 per cent Farm Yard Manure (FYM) or neem cake. Carbofuran at 15 mg a. i./pot gave the maximum reduction in the population of Helicotylenchus dihystera, Tylenchorynchus capitatus and Xiphinema basiri and was followed by FYM, neem cake and T. viride. The plant growth was significantly increased in combination treatments consisting of FYM + carbofuran followed by neem cake + carbofuran. Application of the organic amendments reduced the efficacy of carbofuran.
