Abstract: 
Root-knot nematodes (Meloidogyne spp.) cause major economic damage affecting the quantity and quality of the crop production. In recent years, using of medicinal plants has been considered to many scientists as effective methods for pests and diseases control. In this study effect of different products of clove (essential oils, aqueous extract and ethanol extract) were investigated on second stage juveniles (J2) and eggs of root-knot nematode, Meloidogyne javanica, also protective effect of essential oil of clove was evaluated in control of root-knot nematode in pot conditions. Ethanol extracts of clove (LC50=510 ppm for egg & LC50=646 ppm for second stage of juveniles) had the most toxic effect compared with other products of this plant. In other study, essential oils of clove have negative effect on mobility and movement of J2s and inhibited (37.1%) migration of J2s at 500ppm concentration. Results of pot experiment showed that plant treated with essential oil of clove (200 ppm) had noticeable reduction in infection levels compared with the control. Also, regarding too number of egg mass on root, there was significant difference among treatments (LSD test, P£0.05).
