Mango (Mangifera indica L.) is a seasonal fruit and is cultivated extensively in tropical and subtropical region in India and worldwide. The fruit is processed and mango pulp is extracted in fruit processing industries and kernel is unutilized as industrial waste. Hence, in the present study focused on Totapuri mango kernel cultivar was taken to utilize for bio product development. Soxhlet apparatus with different solvents was used for the crude bioactive compounds extraction from mango kernel powder. The extracted bioactive mass was evaluated for its antibacterial activity against bacterial strains such as Escherichia coli, Pseudomonas putida, Pseudomonas aeruginosa, Shigella sonnei, Klebsiella pneumonia, Xanthomonas oryzae and Staphylococcus aureuss. Further, the extracted crude bioactive compound was tested for antifungal activity against Rhizactonia solani, Curvularia lunata, Alternaria alternate and Fusarium oxysporum. The antifeedent and larval mortality of Spodoptera litura and Helicoverpa armigera activity was studied using the bioactive compound extract. The Methanol Mango Kernel extract (MeOH MK) recorded growth inhibition zone for all the bacteria tested ranging from 21±0.31 to 24±1.55 mm. At 5 % MeOH MK crude extract concentration, the fungal mycelia growth of R. solani was inhibited by 92.90 ± 0.31 %. The highest percent of antifeedent activity was observed in 5% MeOH MK extract recorded as 77.37 %± 0.75 for S.litura and 55. 1.06 for H.armigera. The crude extract of MeOH MK at 5 % concentration recorded 17.8 %± 2.2 mortality rate for S. leutira larva and 100 % mortality rate for H. armigra. The MeOH MK extract was effective as antibacterial, antifungal, antifeedent and larval mortality.
