Deployment of beneficial microbes possessing growth promotion activity and antagonistic potential<br>against pathogens could be a viable and sustainable approach to nullify the deleterious effects of synthetic molecules on nature and<br>to control the disease effectively. In this study, an effort was made to isolate the endosymbiotic fungi associated with allied genera of<br>cardamom and evaluating their antagonistic efficacy under in vitro conditions against the rhizome rot pathogens. Among the endophytic<br>fungi isolated, maximum inhibition of P. vexans was noticed in AsuL4 with 72.4 per cent, followed by HcoL1 with 60.3 per cent, while<br>AmeR2 recorded maximum inhibition 65.3 per cent over control against R. solani followed by HcoL1 with 55.1 per cent inhibition.<br>Among the 17 isolates tested against F. oxysporum, endophytes isolated from Amomum subulatum, AsuLV3 recorded maximum<br>inhibition of 73.8 per cent followed by AsuL4 with 69.9 per cent. The shortlisted efficacious isolates need to be further evaluated<br>under glasshouse and field conditions to confirm their efficacy and could be employed as integral components in cardamom production<br>system to manage rhizome-root rot efficiently, economically and eco-friendly in a sustainable manner.</p> ER -
