Abstract: The research was conducted in Gevgelija – Valandovo vine-growing region during 2007, 2008 and 2009, in two commercial vineyards, on the wine grape variety Vranec and the table grape varieties Michelle Palieri and Italia (Muscat). The experiment consisted of six treated variants and one untreated control, in randomized block design with four replicates per treatment. In 2007 and 2008, grape powdery mildew had not been registered on the clusters in the examined vineyards, while in 2009 Uncinula necator was registered on the clusters in all of the studied variants. The tested fungicides Metrafenone, Tebuconazol and Boscalid + Krezoxim-methil showed higher efficacy on the grapevine, than the fungicides Triadimenol + Folpet, Spiroxamine + Tebuconazol + Triadimenol and Propiconazole.
