Checklist of Host Range of Root-Knot Nematodes (Meloidogyne species and races) in Jordan

Muwaffaq Ramadan Karajeh

Abstract


Root-knot nematodes, RKNs (Meloidogyne species and races) are widely distributed throughout the irrigated agricultural areas in Jordan which differ in their environmental conditions. In this study, host plant range of local populations of RKNs was revised in Jordan and new host samples were collected from some agricultural areas. Thirty one plant species belonging to 19 different plant families were reported as hosts for RKNs in Jordan. Some plant species were recorded for the first time as new natural hosts including: rosemary (Rosmarinus officinalis) to M. incognita race 1, jungle rice (Echinochloa colona), and Mallow (Malva sylvestris) and wild barley (Hordeum spontaneum) to M. javanica. Some of the studied areas e.g. Al-Eina, Karak was recorded as a new site for RKNs. The results of this study may provide useful information for the management of RKNs in Jordan.
