THE IMPACT OF FERTILIZATION AND FOLIAR STIMULATION PRODUCTS BOTH ON INCREASING THE RESISTANCE TO MAJOR PHYTOPATHOGENS ATTACKS, AND ON INCREASING THE QUANTITY AND QUALITY OF WINE GRAPES HARVEST

The paper aimed to demonstrate the impact of fertilization and foliar stimulation products both on increasing the resistance to major phytopathogens attacks, and on increasing the quantity and quality of wine grapes Betaine HCl/Pepsin/Gentian Bitters harvest.Applying the foliar fertilizer products Plonvit Kali (c1), Tytanit (c2) and Optysil (c3) to vines, for a period of three years (2011/2013), in phenophases of intensive growth Plein air - Accessoires of shoots and grapes at approved dosages, simultaneously with pesticide treatment, not only a reduction of pathogenic fungi attack was obtained, but also and an increase of harvest without diminishing the quality of the grapes.
