Efficacy of two of the commonly used oil-cakes viz., mustard and karanj in relation to a standard nematicide, carbofuran on the penetration of nematode juveniles in tomato roots and also the effect of the cakes on plant growth and nematode multiplication was studied. Both the cakes of mustard and karanj significantly reduced penetration of juveniles of Meloidogyne incognita in tomato roots. In comparison to non-amended/untreated soil, there was almost 50% reduction in root penetration by the nematode juveniles in amended soil. The cakes were as effective as the carbofuran treatment. Tomato plants grew remarkably well in mustard and karanj amended soil as compared with that obtained in carbofuran treatment. The shoot length was better in karanj than in mustard amended soil. All the three treatments (karanj, mustard and carbofuran) suppressed the effect of nematode in comparison to nematode alone treatment with regard to shoot weight..Same treatments also suppressed nematode infestation as indicated by root-knot index and number of galls per plant. The same trend was reflected in the case of nematode population in the soil.
