Background and Aims
Xiphinema index and X. diversicaudatum are nematodes that transmit the grapevine fanleaf virus and the Arabis mosaic virus, respectively. These viruses are the two agents mainly responsible for the disease that causes the most economic damage to grapevines worldwide. The infectious degeneration of grapevines affects vine performance and grape composition. The control of Xiphinema populations by soil disinfection is now impossible because of the removal from the market of the last available chemical treatments. In this study, saponins are assessed as an alternative treatment to control nematode populations.
