(2022)Invasive non-native species create an increasing threat to diversity in nature and economics. Invasive species are expected to spread even wider due to climate chance. The Japanese rose (Rosa rugosa L.) is a species widely spread by humans for its decorative value. The japanese rose replaces native plant species and creates problems on seashores, where it thrives. It creates a threat to many endangered biotopes and their plantation. Chondrostereum purpureum (Pers. ex Fr.) has been studied for a biological method for brushwood maintenance. The method has yielded good results on several species of the Rosaceae family , for instance on Black cherry (Prunus serotina Ehrh.) and Pin cherry (Prunus pensylvaica L.f.) This study aims to declare, whether C. purpureum can be viewed as a potential method for controlling the Japanese rose. The effect of C. purpureum on the Japanese rose was studied for one growing season in Lauttasaari, Helsinki. In the study, the roses were cut and the freshly cut surfaces were treated with a C. purpureum solution in June 2021. The data were collected in June-September 2021. Despite the shortness of the study period, the results were promising. The fungal treatment decreased the number of live sprouts and increased the number of dead sprouts. Living sprouts were shorter and the amount of rosehip berries was lower in roses treated using C. purpureum than in roses that were cut only. It seems that the C. purpureum treatment provides a potential method for controlling the Japanese rose.
