Xiphinema index is one of the most important plant-parasitic nematode that is especially damaging the grape and fig orchards by its direct feeding or from the viruses that it transmits. The nematicidal activities of fifteen plant extracts were tested in vitro against adult females of this nematode. The extracts were isolated from leaves and small branches of five endemic trees viz Phoenician juniper (Juniperus phoenicea L.); mastic tree (Pistacia lentiscus L.); strawberry tree (Arbutus pavarii Pamp.); Phillyrea (Phyllarea angustifoliaL.) and Carob (Ceratonia siliqua L.)] from the Al-Jebel Akhdar region of northeast Libya. Three solvents ie water, ethanol, and hexane were used to isolate the extracts. Highest nematicidal activity was reported from the ethanolic extract of J. phoenicea (27 minutes for LT50 and 47 minutes for LT90), followed by hexane extract of Pistacia lentiscus L. with 232 and 350 minutes for LT50 and LT90, respectively. The activities of other extracts were significantly less than these two extracts.
