Mulberry, a perennial and economically important crop forming the foundation of the sericulture industry, is highly susceptible to soil-borne diseases, particularly root rot, which leads to severe plant mortality and reduced leaf yield. The present investigation clearly established Rhizopus sp. as a major root rot causing pathogen of mulberry, isolated from diseased roots and the rhizosphere. The comparative in vitro evaluation of biocontrol agents, fungicides, and herbal oils demonstrated significant variation in their antagonistic efficacy against the pathogen, highlighting the importance of a targeted and integrated disease management approach. Among the fungal biocontrol agents, all three Trichoderma species exhibited strong antagonistic activity against Rhizopus sp., with T. viride showing the highest mycelial inhibition, followed closely by T. harzianum and T. asperellum. The fungicide evaluation revealed marked differences in efficacy across fungicides and concentrations. Propiconazole and Carbendazim consistently recorded the highest inhibition of Rhizopus mycelial growth, followed by Hexaconazole and Difenoconazole, especially at higher concentrations. The assessment of herbal oils Eucalyptus oil emerged as the most effective herbal oil, followed by Cinnamon oil, while Clove, Pongamia, and Basil oils.
