Effect of Entomopathogenic Nematodes and Their Mutualistic Bacteria to Control of Root-knot Nematodes (Meloidogyne javanica) on Tomato in The Greenhouses

29268

In this study, the effects of four entomopathogenic nematode species (EPNs) (Steinernema carpocapsae, S. feltiae, S. glaseri and Heterorhabditis bacteriophora) and the supernatants of their symbiotic bacteria (Xenorhabdus bovienii and Photorhabdus luminescens kayaii) were evaluated on eggs (hatching) and second stage juveniles (J2s) (mortality) of root-knot nematodes (Meloidogyne javanica) on tomato plants (SC-2121 variety) grown in the greenhouse. Data were recorded included total number of egg masses caused by M. javanica on the tomato roots for each plant, plant height (cm), fresh and dry weight of the plant shoots and roots (g). S. feltiae (aqueous suspensions and infected insect cadavers) and X. bovienii have been found to be effective to control of root-knot nematode.
