Abstract. A survey of phytoparasitic nematodes associated with grape and other important crops in Morocco was undertaken in 2004, 2005 and 2006. The root-knot nematodes, Meloidogyne incognita and M. javanica were very common on grape, peach, banana, common bean and pea. Xiphnema index, X. Pachtaicum and Mesocriconema xenoplax were found on grape. Tylenchulus semipenetrans, Hemicycliophora arenaria and Xiphinema sp. were found on Citrus. Pratylenchus vulnus was found on peach and almond, and P. thornei was common on chickpea. Grapevine Fan Leaf Virus (GFLV) was detected in association with X. index in four locations Morocco.
