Comparison of the Efficacy of Ground Wild Cucumber Fruits, Aldicarb and Fenamiphos on Suppression of Meloidogyne incognita in Tomato

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
