AbstractThe ectoparasitic nematode Xiphinema index Thorne and Allen is economically important in grapes Vitis vinifera L., both as a root parasite and as a vector for grapevine fan leaf virus (GFLV). The control of GFLV vector is one of the main strategies of the disease management. The using of nematicides and soil amendments is one of traditional methods for nematode controlling. The objective of this research was to evaluate the nematicidal effect of the nematicide Vyox, poultry manure and salicylic acid for controlling Xiphinema index on grapevines. The nematicidal was evaluated determining the nematode population densities in 200 ml of soil. The results revealed that both of nematicide Vyox and poultry manure have a significant activity against X. index 15.6 and 162.4 respectively compare to the positive control 557.4 nematode/200ml soil. The best results were obtained from the combination between nematicide Vyox, poultry manure and salicylic acid which significantly reduced X. index populations (P<0.05) compare to the single treatments and positive control.
