Abstract
ABSTRACT Field-grown ‘Sauvignon Blanc’ winegrapes fertigated with various concentrations of N:P:K (7:3:7) for four consecutive years (1988-1991) were evaluated for susceptibility to powdery mildew (Uncinula necator). Vines fertilized with low NPK concentrations were significantly more susceptible to disease than plants fertilized with high levels. The number of powdery mildew-infected clusters and the severity of the infection were much greater on plants fertilized with a low level of NPK (about 50%), as compared to those of the high fertilization levels (9.5%). In addition, total proteins content and β-l, 3-glucanase activity in berries from low NPK-fertil-ized plants was greater than that of the high fertilization level in plants.
