During a field study in the Baili Azalea Forest Area in Guizhou Province, China (27°12'N, 105°48'E) between May and July 2023, symptoms of leaf spot were observed on Franch. The incidence of leaf spot on leaves was about 12% in a field of 1 hm2, significantly reducing their ornamental and economic value. The affected leaves bore irregular, grey-white lesions with distinct dark brown borders, accompanied by black conidiomata.

Biocontrol strategies utilizing antagonistic microorganisms present a promising alternative for controlling plant pathogens. Bacillus megaterium L2 has been identified as a potential microbial biocontrol agent in our previous study; however, its efficacy in controlling pathogens has yet to meet current demands.

- Rosa roxburghii, known as Cili in China, is a fruit crop growing in mountainous regions, particularly in Guizhou province, where leaf spot symptoms affected 20-30% of plants in 2021, leading to potential loss in fruit quality and harvests.
- The leaf spot symptoms were identified as irregular brown spots on the leaves, and a study for isolating the pathogen involved collecting symptomatic leaves and culturing them on potato dextrose agar.
- Three isolates of the pathogen were obtained, with isolate F3-Y-21 selected for further analysis, revealing morphological characteristics consistent with Didymella segeticola, confirming its identity through genetic amplification.
Rosa roxburghii Tratt is a plant from the Rosaceae family whose fruits are rich in vitamins, dietary fiber, flavonoids, phenolic acids, and other active components (Jiang, et al. 2024). In July 2023, about R.
