A mass of unusual symptoms on leaves and branches on different cultivars of grapes were found in year 2001 on Primorska (Coastal) region. Symptoms were expressed on loss of vitality of plants, leaves yellowing, but they were similar to symptoms caused by mite (Calipitrimerus vitis Nal.). The most mentioned symptoms were found on cultivars like Sivi pinot and Zeleni sauvignon (before Furlanski tokaj). During detail observations from 2002 to 2006 a lot of plants with symptoms of almost all vine cultivars were found. With detail examinations of infected leaves we found out that mentioned symptoms are not consequence of acarinosis and that the real reason for these is something else. Regards to symptomatic and the way of appearance of symptoms (first of all on young plants) we suppose, that the real reason for this, is Petri disease, one of diseases of wood decline on vine plants. The widespreading of mentioned disease is fact, so we should face with this new trouble.
