Abstract: "Due to the intense ash dieback in Europe, which begins with the appearance of leaf infection, this study presents the results of the research on the impact of a selected isolate Pseudomonas koreensis R4.45P on the development of Hymenoscyphus fraxineus in the rachises of Fraxinus excelsior. Preliminary in vitro testing of P. koreensis R4.45P showed a statistically significantly lower growth of H. fraxineus compared to control cultures that were not exposed to this bacterium. The results of the in planta test on F. excelsior seedlings showed a statistically significant decrease in dieback occurrence and the length of necrotic lesions caused by H. fraxineus in rachises treated with P. koreensis R4.45P compared to untreated rachises. Additionally, leaf mortality in F. excelsior seedlings treated with P. koreensis R4.45P was statistically significantly lower. This study is the first to show the possibility of application of antagonistic bacteria P. koreensis R4.45P to effectively slow the initial stage of H. fraxineus development."
