Introduction This study aimed to identify the pathogen responsible for leaf blight in Cyclocodon lancifolius , investigate its biological characteristics, and effective synthetic fungicides. Additionally, this examined changes physiological biochemical indices of leaves following infection screened biocontrol bacteria that inhibit growth, providing a scientific basis preventing managing C. . Methods Pathogens were isolated from interface healthy infected tissues identified through morphological molecular methods. Amplification sequencing three genomic DNA regions—internal transcribed spacer region, translation elongation factor 1-α, glyceraldehyde-3-phosphate dehydrogenase ribosomal DNA—were performed, followed by construction phylogenetic tree. The characteristics pathogens under various temperature pH conditions different nitrogen carbon sources analyzed using mycelial growth rate method. antifungal effects 13 chemical agents evaluated poisoned medium method Changes indicators post-infection also assessed. An antagonistic experiment was conducted screen bacteria. Results A total 29 potential pathogenic strains tissues, with Koch’s Postulates confirming Stemphylium lycopersici as key causing disease. Growth analysis S. revealed optimal at 20°C 6, lactose or maltose serving most suitable source histidine preferred source. Among fungicides tested, strain DHY4 exhibited greatest sensitivity 400 g/L flusilazole. Significant differences ( p < 0.05) observed superoxide dismutase, phenylalanine ammonia-lyase, peroxidase, polyphenol oxidase, catalase, malondialdehyde levels between treated control groups 3 days post-inoculation. DYHS2, Bacillus subtilis demonstrated an inhibition 51.80% against dual-culture experiments showed relative 78.82% detached assays. Discussion These findings provide valuable insights into newly causal agent underscoring B. DYHS2 such flusilazole disease management strategies.
