During the present study the efficacy of ground Cucumis myriocarpus fruits and synthetic non-fumigant nematicides on suppression of Meloidogyne incognita numbers and effect on growth of tomato was evaluated and compared in a microplot experiment. All microplots were artificially inoculated with second-stage juveniles of M. incognita. Treatments included an (i) untreated control, application of (ii) Cucumis, (iii) aldicarb (a. i. = 150 g/kg), (iv) fenamiphos (a. i. = 100 g/kg) each at the product quantity of 42 kg/ha. The study was repeated in the second year using randomized complete block design with 10 replications. The application of products reduced nematode numbers in tomato roots (83-99%) and increased tomato fresh fruit yield (72-94%). Generally, the effect of the three applications on the parameters measured were not significantly (P = 0.05) different from one another, confirming the potent nematicidal properties of ground C. myriocarpus fruits.
