Bamboos are one of the fastest-growing plants globally and play a significant role in the livelihoods of local communities by serving as raw materials in several industries, including pulp and paper, construction, agriculture, horticulture, basketry, transportation and fishing. Globally, there are approximately 1,575 bamboo species distributed across over 116 genera. However, bamboo productivity is threatened by multiple biotic and abiotic factors, with diseases, especially bamboo blight caused by Fusarium semitectum, posing a significant but understudied challenge in Northeast India. This study evaluates the in vitro and in vivo antifungal efficacy of aqueous leaf extracts from Mimosa diplotricha, Senna alata and Wedelia trilobata against F. semitectum. The in vitro antifungal activity was assessed using the poison food technique at concentrations of 20%, 25%, 30%, 35% and 40% with three replications. The in vivo experiment followed screenhouse pot trials with a completely randomized design and data from both assays were statistically analyzed using ANOVA. Among the treatments, S. alata extract at 40% concentration resulted in the highest mycelial inhibition (71.94%) at 10 days after inoculation (DAI) under in vitro condition and the lowest Per cent disease incidence (50.00%) after the second spray under in vivo condition. Whereas, under in vitro condition, M. diplotricha and W. trilobata showed up to 71.66% and 59.04% mycelial inhibition at 10 DAI, respectively. These findings suggest that S. alata is the most effective plant extract against bamboo blight, followed by M. diplotricha with W. trilobata being the least effective. These findings suggest that potential of plant-based extracts, especially S. alata offers promising, environmentally safe alternatives for managing F. semitectum, a key pathogen responsible for bamboo blight. Further large-scale field evaluations are recommended to optimize application protocols and integrate these botanicals into sustainable disease management strategies for bamboo cultivation.
