The Bujorul grape variety is a relatively recent variety created in Galați, which has very good organoleptic qualities, but it is not a well-known variety, and its expansion in culture is low. The present article aims to bring some clarifications regarding the resistance of the Bujorul variety to downy mildew and powdery mildew, the most widespread fungal diseases that affect the foliage of vines every year of cultivation. In the article, the effects of manna and powdery mildew on the Bujorul variety are compared with the attack of these fungi on other popular grape varieties, such as the Nero, Victoria, Muscat Hamburg, Moldova and Chasselas doré varieties. The research was done in 2022, in a private collection of table grape varieties located in Timiș County, in Urseni village. The year 2022, thanks to the water and temperature regime, influenced predominantly the powdery mildew attack than the downy mildew attack. The obtained results were interpreted statistically and comparisons were made with each variety, in order to get an overview of the influence of the climate on the attack of these diseases on the Peony variety compared to the other varieties, on which a lot of research has been done in different areas of the country regarding their response to the attack. In the paper, we tabulate only the degree of disease attack and graphically illustrate the obtained data.
