Abstract

The following virus diseases have been identified in Israel: Grape fanleaf, Grape yellow mosaic, Grape leaf-roll virus, as weil as the mycoplasma disease Flavescence doree. Among them grape fanleaf and leaf-roll viruses are widespread, while Flavescence doree is most common in the hot valleys of north-east Israel. A new species of nematode, Xiphinema italiae, has been identified as vector of grape fanleaf virus. Mechanical inoculation of herbaceous plants, while helpful, does not solve the problem of a rapid indexing.

Viruskrankheiten der Rebe in Israel

Folgende Viruskrankheiten wurden in Israel nachgewiesen: Fan leaf, Gelbmosaik, Blattrollkrankheit sowie die durch ein Mycoplasma hervorgerufene Flavescence doree. Von ihnen sind Fan leaf und Rollkrankheit weit verbreitet, während Flavescence doree in den heißen Tälern von Nordost-Israel sehr häufig ist. Eine neue Nematodenart, Xiphinema italiae, wurde als Vektor des Fan-leaf-Virus ermittelt. Mechanische Übertragung auf krautige Pflanzen löst das Problem eines schnellen Nachweises nicht.
