“…In South Africa, 16 species of Xiphinema were found in soil samples analysed from five viticulture regions in the Cape Province and X. index was present in three of these regions (Malan & Meyer, 1994). The population of X. index decreases with soil depth.…”

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.

“…include poor vigour, stunted growth and poor yields (Seinhorst & Sauer, 1956). It is very important to note, however, that Xiphinema index (Thorne & Allen, 1950), which is present in high numbers in some viticulture regions in South Africa, not only damages the roots of susceptible grapevine cultivars, but also is a vector for the grapevine fanleaf virus (Malan & Meyer, 1992, 1994. (Hugo et al, 2014).…”

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.
