Abstract: 
Dendrocalamus asper (Bamboo) is an essential component of forest ecosystems, whose health and survival are intrinsically linked to complex interactions with its microbiome. This study focuses on the pathogenic dynamics between the fungi Arthrinium spp. and Erwinia spp. Bacteria and their impact in the shoots wilting and culm rot in bamboo. Through humid chamber induction methods and selective cultivation techniques, pathogenic strains that significantly affect the regeneration and propagation of bamboo were identified and isolated. The investigation revealed a pathogenic synergy resulting in a high prevalence of diseases, 97% of the shoots evaluated showed signs of deterioration. Morphological identification challenged conventional techniques due to the variability of Arthrinium spp—conidia, suggesting the need for more specific identification methods. The findings suggest that regulating soil pH and using beneficial biofilms could be promising strategies to mitigate bacterial infection. This study highlights the importance of sustainable management and in-depth knowledge of microbial ecology for integrated disease management in bamboo ecosystems. Under-standing these microbial interactions is crucial for developing effective control strategies and long-term conservation of these vital ecosystems.
