Abstract:
Efficacy of biocontrol control agents such as Trichoderma harizanum UHSBTH15, T. viridae UHSBTV9, Bacillus amyloliquefaciens UHSBBA9, B. amyloliquefaciens UHSBBA10, B. subtilis UHSBBS1 and Cryptococcus albidus UHSBCA7 on quality attributes and shelf life of papaya cv. Red Lady was evaluated. The fruits harvested at mature green stage with 1-2 yellow streaks on the surface, were washed and treated with respective bio-control agents and stored at ambient storage. Further, various physico-chemical parameters are analysed. Papaya fruits treated with Bacillus amyloliquefaciens UHSBBA9 provided an effective control in reducing physiological weight loss and% disease index delayed changes in the peel colour maintained firmness, titratable acidity, total soluble solids, β carotene content during 9 days of storage. Fruits treated with B. amyloliquefaciens UHSBBA9 also confirm the sensory evaluation along with maximum shelf life of 8.00 days.
