Abstract :In this study, the nematicidal effects of four essential oils, Rosmarinus officinalis L. (Rosemary), Thymus vulgaris L. (Thyme), Sesamum indicum (Sesame), Lavandula spp. (Lavender), on Meloidogyne chitwoodi Golden et al., 1980 (Tylenchida: Meloidogynidae) were investigated by petri experiments. In the study, 125 ppm, 250 ppm, 500 ppm, 10000 ppm, 20000 ppm, 30000 ppm concentrations of essential oil were used to prevent egg hatching and to evaluate the lethal effect on second stage juveniles. The results showed that each essential oil inhibited hatching at 24 h, 48 h, 72 h and 7 days at varying levels. Sesame and lavender oils also had the highest rate of preventing egg hatching. Lavender, thyme, and rosemary oils exhibited higher juvenile mortality than sesame in all concentrations. More than 92.2% mortality of M. chitwoodi juveniles occurred after a 24 hour exposure to a 10000 ppm oil solution of lavender, thyme, rosemary. All exposure times and concentrations resulted in a 100% mortality rate of M. chitwoodi in thyme. The most effective result within 24 hours was observed in thyme oil. The results suggest that it should be set up pot experiments for in vitro results.
