“…In this case, none of the Vitis rootstocks showed tolerance to infection by X. index as occurred in rootstocks 110R and SO4 infected by Meloidogyne spp. Nevertheless, contradictory results have been previously reported for SO4 rootstock, which was found susceptible and sustaining high levels of root damage (Malan & Meyer, 1993) or moderately resistant (Harris, 1983) to X. index . Similarly to Meloidogyne spp., pathogenic variability has also been reported for X. index depending on the geographical origin of the tested population (Coiro et al.…”

Host suitability of Vitis rootstocks to root‐knot nematodes (Meloidogyne spp.) and the dagger nematode Xiphinema index, and plant damage caused by infections

et al. 2011

The host suitability of commercial Vitis rootstocks commonly used in Spain (161-49C, 41B, 1103P, 110R, 140Ru and SO4) to root-knot nematodes (Meloidogyne arenaria, M. incognita, M. javanica) and Xiphinema index, and damage caused by nematode infection were determined under controlled conditions. The three root-knot nematodes reproduced with a rate higher than one in all rootstocks, indicating that they are suitable hosts for these nematodes. Growth of rootstocks infected with the root-knot nematodes was less vigorous than that of nematode-uninfected controls in the majority of the rootstocks studied. Root infection resulted in moderate to severe root galling in all rootstocks. The shoot and main stem diameters appeared to be the most sensitive variables of damage caused by infection by Meloidogyne spp., with reduction rates from 36% and 53% in 161-49C to 57% and 66% in 140Ru, respectively. The shoot height was not significantly affected by the root-knot nematodes and the root fresh weight generally increased as a consequence of intensive galling. The nematode X. index caused significant root damage with a reproduction factor higher than one in all rootstocks. However, reproduction factor was significantly influenced by the rootstock and significantly decreased by about 12-fold (5AE7 to 18AE1-fold) with the increase in inoculum density from 100 to 1000 nematodes per plant. The root dry weight was reduced by X. index infections, and was the plant growth variable most affected by the nematode infection in all rootstocks at both inoculum densities. Meloidogyne arenaria, M. incognita, M. javanica and X. index, prevalent in many world vineyards, are all shown to have a damaging effect on the six tested rootstocks.

“…Their feeding behaviour slows down the root development of susceptible cultivars (Malan & Meyer, 1993). For vines, X. index is the most economically important dagger nematode in South Africa, as they not only damage the roots of susceptible vine cultivars, but also are able to transmit grapevine viruses (Malan & Meyer, 1992;Kleynhans et al, 1996;Nicol et al, 1999;Malan & Hugo, 2003;Van Zyl et al, 2012).…”

Plant-parasitic nematodes are a problem in vineyards worldwide, with some species acting as vectors of grapevine soil-transmitted viruses. Global pressure on the use of soil-applied chemical nematicides has led to a search for new control options, or for alternative methods to suppress plant-parasitic nematodes as part of integrated pest management. This paper gives valuable background information on the use of cover crops with biofumigation properties for the suppression of plant-parasitic nematodes in vineyards.

“…The 110R rootstock, which is often used in South Africa for its phylloxera resistance and good vigor, is susceptible to X. index feeding. However, Harmony, Freedom, 3309C and Schwarzmann had some degree of resistance (Harris, 1983;Malan & Meyer, 1993). More rootstock examples are named and described in Table 2 in terms of their resistance or susceptibility towards X. index feeding.…”

The dagger nematode, Xiphinema index, is considered a major pest in grape growing countries. Xiphinema index is especially important because of its ability to transmit Grapevine fanleaf virus when feeding on grapevine roots. This paper provides a comprehensive and updated review of the classification, genetics and biology of Xiphinema index, and its relationship with grapevine fanleaf virus. Current control measures, as well as past and present efforts to breed resistant grapevine rootstocks, are presented.
