This study presents the results of the organic diseases management strategy applied to the climbing edible rose plantation. The research was carried out on the Experimental Field of the Faculty of Horticulture - USAMV Bucharest established in 2015 with three climbing cultivars from the David Austin collection: Crown Princess Margareta, Falstaff, and Brother Cadfael. Two main pathogens which affect susceptible rose cultivars worldwide were detected: Podosphaera pannosa var. rosae (powdery mildew) and Diplocarpon rosae (black spot). Our management protection scheme was based on environmentally friendly practices and organic products to prevent the pathogens severity and/or as natural resistance inducers. Both black spot and powdery mildew were present with a very low degree of attack (below 1%). These results could be explained by the efficacy of our organic scheme in preventing and limiting both pathogens incidence and severity. The influence of varieties and their position in the field on disease occurrence were analysed.
