Ecofriendly synthesis of nanoparticles is new, safe, speedy and emerging trend in field of nano-technology. The present study conducted at Post Harvest Technology laboratory, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola and aimed to synthesized silver nano-particles from silver nitrate solution using leaf extracts of Neem, Tulsi, Custard apple and Guava. The reason of using leaf extracts was the biomolecules present in the plants act as reducing and stabilizing agents and increase the rate of reduction of silver metal and synthesis of nano-particles. The characterization and detection of synthesized nano-particles were confirmed using the SPR opticle absoption band peak ranges from 420 to 560 nm by UV-visible Spectrophotometer and screening of antimicrobial potential against citrus fruit pathogen by disk diffusion method. These biosynthesized silver nano-particles were mixed with guargum as a sticking agent and used as a coating material for Nagpur mandarin to increase the shelf life of mandarin fruits. It was found that green synthesized silver nano-particles increase the shelf life of Nagpur mandarin by arresting weight loss, fruit decay rate and microbial count due to antimicrobial activity of silver nano-particles and leaf extracts without affecting quality of fruits for two months.
