The thesis evaluates the incidence and impact of secondary pathogens on grapevine cultivars resistant to downy mildew and powdery mildew. The study lasted an entire growing season on the vineyards owned by Veneto Agricoltura and managed by biological cultivation/ organic farming. The study took into consideration 3 resistant varieties: Merlot Khorus, Sauignon Nepis and Sauvignier Gris; in addition, Glera was also examined as it currently appears to be the most cultivated variety in the study area. Due to the very rainy weather conditions of the year 2023, various diseases emerged with different incidence and intensity in the 4 cultivars observed in the study. The attack of pathogens has always been under control and has never reached situations that could compromise the harvest in both quantitative and qualitative terms.
La presente tesi valuta l’incidenza e l’impatto dei patogeni secondari in viti resistenti a Peronospora e Oidio. Lo studio è durato un’intera stagione vegetativa in un vigneto locato a Pramaggiore (VE), gestito in regime biologico. Nello studio sono state prese in considerazione 3 varietà resistenti: Merlot Khorus, Sauignon Nepis e Sauvignier Gris; inoltre, è stata esaminato anche il vitigno Glera che attualmente risulta essere la varietà maggiormente coltivata nella zona dello studio. A causa dell’andamento climatico molto piovoso dell’annata 2023 sono emerse diverse fitopatologie con diversa incidenza ed intensità nei 4 vitigni presi in osservazione. L’attacco dei patogeni è sempre stato sotto controllo e non ha mai raggiunto situazioni tali da compromettere il raccolto sia in termini quantitativi che qualitativi.

Abstract
The thesis evaluates the incidence and impact of secondary pathogens on grapevine cultivars resistant to downy mildew and powdery mildew. The study lasted an entire growing season on the vineyards owned by Veneto Agricoltura and managed by biological cultivation/ organic farming. The study took into consideration 3 resistant varieties: Merlot Khorus, Sauignon Nepis and Sauvignier Gris; in addition, Glera was also examined as it currently appears to be the most cultivated variety in the study area. Due to the very rainy weather conditions of the year 2023, various diseases emerged with different incidence and intensity in the 4 cultivars observed in the study. The attack of pathogens has always been under control and has never reached situations that could compromise the harvest in both quantitative and qualitative terms.File | Dimensione | Formato | |
