Abstract
Vineyards in all five of South Australia's grapegrowing districts were surveyed for plant parasitic nematodes. Root-knot nematodes (Meloidogyne spp.) occurrcd in four districts, and were present in almost all vineyards with sandy soil in the Riverland, Barossa Valley and Central districts. Four species (M. arenaria, M. hapla, M. incognita and M. javanica) were identified. Citrus nematode (Tylenchulus semipenetrans) was wide-spread in Riverland vineyards, and isolated infestations were found in other districts. Other plant parasitic nematode genera found during the survey were Helicotylenchus, Macroposthonia, Paratrichodorus, Paratylenchus, Prat ylenchus, Tylenchorh ynchus and Xiphinema.
