- Abstract
Climate significantly influences vineyard placement and grape variety selection. Grapes cultivated in cold climates typically yield higher quantities but have lower sugar content and higher acidity, resulting in high-quality table wines. Cool climates are particularly conducive to white wine production. However, susceptibility to frost poses a challenge in colder regions, potentially damaging crops and hindering proper ripening. The present study aims to explore the relationships between three primary fungal pathogens that pose significant threats to grapevines, within the specific climatic conditions of the experimental area, using multiple regression analysis and response surface methodologies. The research was conducted in Hunedoara County, Geoagiu Depression using Feteasca alba grape variety. Three phytosanitary treatment schemes, including two experimental treatments and one untreated control, were implemented. The targeted pathogens include Plasmopara viticola, Uncinula necator, and Botrytis cinerea. Statistical analysis was performed using the STATISTICA v.8.0 software for Windows. Graphical representations with response surfaces and multivariate analysis were used to examine pathogen interactions. According to our study, strong positive correlations (resulted between pathogens, whatever phytosanitary fight scheme was used.
