Abstract Natural products from plants are pulling in more interest in exploration due to their therapeutic properties like, mainly because of the drug-resistance in microbes against synthetic drugs. Thus, the present study was designed to assess the antimicrobial and antioxidant actions of some Agro-waste (garlic, ginger, onion, potato) peel extracts. Ginger peel extracts exhibited the highest FRAP (0.273±0.044 mm Fe2+ Eq/g dry weight) while garlic peel extracts exhibited the highest TAC (0.47±0.0452 mm AAE/g dry weight) values among all selections. The antimicrobial activity of the peels was evaluated against different pathogenic bacterial and fungal strains i.e.; Escherichia coli, Bacillus megaterium, Bacillus cereus, Staphylococcus aureus, Colletotrichum falcatum, Fusarium moniliforme, and Rhizoctonia solani. Among all extracts, ginger peel extracts exhibited maximum inhibition against all bacterial strains, while onion peel extracts exhibited zero inhibition against any bacterial strains. All extracts exhibited maximum inhibition against Staphylococcus aureus except onion peel extracts. Positive inhibition against all fungal strains was observed for all samples, with maximum inhibition against Colletotrichum falcatum. The outcomes of the study, therefore reveal that Agro-wastes have a powerful antimicrobial and antioxidant potency and thus can be used for many medicinal purposes, which will likewise be helpful in waste management and environmental safety.
