Screenhouse experiments were conducted to test the efficacy of cowdung and urine separately and in combination in the control of root-knot nematode of tomato. Equal quantities of cowdung, urine and their mixture were separately made up to one litre with autoclaved soil. Two weeks old seedlings of tomato raised in autoclaved soil were transplanted into soil manure mixture and inoculated with 1,000 second stage larvae of Meloidogyne incognita race I. Treatments were completely randomized and effects assessed based on plant height, dry weight, extent of galling and the nematode multiplication factor. Results obtained showed that cowdung, urine, and their mixture produced significantly higher result than the untreated control. Similarly, the mixture of urine and cowdung, produced significantly higher results than the separate treatments.

Key words: Meloidogyne incognita, Lycopersicon esculentus, cowdung, urine, tomato.
