Detection of arabis mosaic nepovirus in Austria
In Austria, in 1993, a survey was carried out in the Burgenland wine-growing region on the occurrence of grapevine fanleaf nepovirus, arabis mosaic nepovirus (EU Annex II/A2), grapevine leafroll-associated closterovirus type I and type III. Samples were tested by DAS ELISA. In Central Burgenland, only grapevine leafroll-associated closterovirus type I and type III were found. They were also predominant in other parts of Burgenland. Grapevine leafroll-associated closterovirus, arabis mosaic nepovirus and grapevine fanleaf were found in the south of Burgenland, at levels of approximately 2 to 3.5 %. The EPPO Secretariat had previously no information on the occurrence of arabis mosaic nepovirus in Austria.
