Rhizospheric Streptomyces as a Game-Changer in Tea Disease Suppression

The sustainability of tea cultivation is increasingly threatened by diverse fungal phytopathogens that impair leaf quality, reduce biomass, and significantly limit yield. Conventional chemical fungicides, while effective, pose escalating concerns related to environmental toxicity, pathogen resistance, and food safety. Addressing these challenges requires a paradigm shift toward biologically driven plant protection strategies. In this context, the present study explores the biocontrol potential of Streptomyces spp. as a robust and eco-compatible alternative for disease management in tea ecosystems. Renowned for their prolific production of bioactive secondary metabolites and lytic enzymes, Streptomyces species exhibit strong antifungal activity against a wide range of phytopathogens. Beyond direct antagonism, their ability to establish stable populations in the rhizosphere enables the activation of induced systemic resistance and improved nutrient dynamics in host plants. This study further evaluates their adaptability and functional efficiency in the acidic soil characteristic of tea plantations, highlighting their ecological resilience. The findings emphasize the potential of Streptomyces-based bio-inoculants as a sustainable intervention to reduce chemical dependency, enhance plant health, and promote long-term agricultural resilience. This approach aligns with global efforts toward environmentally responsible and integrated disease management in high-value plantation crops.
