摘要

Root-knot nematodes (RKNs) of the Meloidogyne spp. are the most significant plant-parasitic nematodes that damage tomatoes in central Greece (Thessalia region). Apart from the direct damage to roots, Meloidogyne spp. enhance wilt disease caused by either Fusarium oxysporum or Verticillium dahliae. It is well known that the free living second stage juvenile (J2) causes most injury to plants. J2s move in the soil water films to reach the root zone. Therefore, the elimination or halt of J2s into soil could be an import strategy to control root-knot damage. An environmentally friendly approach to control RKNs is to apply the widely known RKN-parasite bacterium Pasteuria penetrans. P. penetrans (Pp) shows great potential as a biocontrol agent as it is capable of immobilising RKN J2s (Vagelas et al., 2006).
