“…Complete resistance to root‐knot nematode in a glasshouse trial suggests satisfactory field performance (Lider , Sauer , Walker et al , Cousins and Walker ). Roots of resistant rootstocks, however, may still allow for root‐knot nematode reproduction at a low level with negligible impact on vine health (Loubser and Meyer , McKenry and Kretsch , McKenry et al ). To date, this study represents the most comprehensive screening of grapevines for response to M .…”

Background and Aims: Root-knot nematodes (Meloidogyne spp.) are endo-parasites of plant roots and parasitisation can lead to diminished grape yields. Worldwide viticulture production is impacted primarily by four species of root-knot nematode (Meloidogyne arenaria, Meloidogyne hapla, Meloidogyne incognita and Meloidogyne javanica). Meloidogyne javanica is the predominant root-knot nematode found in Australian vineyards. A glasshouse-based experiment was conducted to identify grapevine cultivars and accessions with complete resistance (i.e. no reproduction of nematode) to an aggressive pathotype of M. javanica isolated from an Australian vineyard. Methods and Results: Single-grapevine plants were inoculated with approximately 1500 second stage juveniles of M. javanica in a replicated study. Six weeks after inoculation, roots were washed free of soil, and egg masses were stained and tallied. The final dry mass of roots was measured to determine the ratio of egg masses to root mass. Conclusions: Complete resistance to M. javanica was found in 42 of 75 Vitis cultivars and accessions screened. Significance of Study: The M. javanica resistant cultivars and accessions identified in this study provide valuable material for future breeding in order to develop new rootstocks for the Australian wine and grape industry with durable resistance to root-knot nematode.

“…(dagger nematode) (McKenry, 1992;Pinkerton et al, 1999;Walker & Stirling, 2008). In Australia, plant-parasitic nematodes are problematic in all the different grape-growing regions (Nicol et al, 1999), and in South Africa grapevines are also host to a wide range of pest nematodes (Smith, 1977;Loubser & Meyer, 1987a;1987b).…”

“…The use of resistant rootstocks also forms part of an integrated approach to nematode management in South African vineyards. The rootstocks available are classified as resistant, moderately resistant, moderately susceptible and susceptible, with most of the rootstocks available having genetic resistance to rootknot nematodes (Loubser & Meyer, 1987b). No rootstocks currently are available that are resistant to C. xenoplax (Storey, 2012).…”

In South Africa the use of annual cover crops is an established soil cultivation practice in vineyards that is environmentally friendly and financially sustainable in the long term. Species from the Brassicaceae family are well known for their biofumigation potential. In this study, Sinapis alba (white mustard), Brassica napus cv. AV Jade (canola), Brassica juncea cv. Caliente 199 (Caliente), Eruca sativa cv. Nemat and Avena sativa cv. Pallinup were established as cover crops in a vineyard for three growing seasons and evaluated for their biofumigation impact, as well as crop host impact on the suppression of economically important plant-parasitic nematodes. Mechanical and chemical cover crop management practices on Criconemoides xenoplax (ring nematode) and Meloidogyne javanica (root-knot nematode) numbers were determined. Canola and Caliente showed a consistent reduction of C. xenoplax present in the vine row 60 days after the management practices applied at the end of the third growing season. This trend was found during the three-year trial period for all different sampling periods (0, 15, 30 and 60 days). Lowered numbers for the total plant-parasitic nematodes were also found for the three-year trial period measured at 60 days after the management practice sampling period. The results can be attributed mainly to the crop host status of the two cover crop species towards C. xenoplax. White mustard showed a constant increase in C. xenoplax numbers in the vine row over the three-year period compared to the treatments in which no cover crop was sown.

“…More than 170 species of Xiphinema have been identified worldwide on a wide range of hosts. Sixty-nine Xiphinema species have been reported in South Africa, although only four were implicated in plant virus transmission: X. americanum Cobb, X. diversicaudatum Thorne, X. index Thorne and Allen, and X. italiae Meyl (Loubser & Meyer, 1987a); the first three are common in South African vineyards (Malan, 1995). They are found in a variety of soils and are migratory ectoparasites (Shurtleff & Averre III, 2000).…”

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.
