The obtained results showed that, the highest occurrence genus was root-knot nematode, Meloidogyne with percentages of 64.6%, 52.6%, 51.0% and 50.1% in broad bean, sowthistle, nut grass and potato, respectively. The lowest occurrence genus was Xiphinema with percentages of 1.0%, 1.1%, 1.3% and 1.4% in clover, nutgrass, potato and broad bean, respectively.
