Abstract

During the last five years (2003-2007) in certain vineyards in the area of Kruševac, Varvarin, Ražanj, Negotin, Vršac and the surroundings of Novi Sad, there were noticed individual vine plants with specific symptoms of dying out and rotting, even up to 20% of them. The symptoms were especially expressed on the sorts Italian Riesling, Rhine Riesling, and Sauvignon Blanc. “Characteristic” symptoms on the diseased vine plants were expressed in the form of chlorosis and curling of the leaves in the form of a goblet, which usually became smaller than the healthy ones, then the appearance of lastar with significantly shortened internodes, whereas on the cross- section there was often noticed a necrotic zone of the woody part of the tissue in the shape of the letter “V”. Based on the research of pathogen, morphological and cultivating characteristics of the isolated pathogen, as well as by applying molecular methods, it has been found out that the causative agent of the noticed symptoms of disease is a phytopathogenic fungus Eutipa lata.
The paper describes the significance of the mentioned species, symptoms which it causes and hosts which it attacks, as well as the cycle of development, with special emphasis on its suppression.
