Abstract
Papaya (Carica papaya L.) fruits are highly perishable commodity suffer from heavy post harvest losses and cause about 8 to 18 per cent losses during storage to marketing. Post harvest losses in papaya are caused by biotic and abiotic factors. Among different biotic factors, anthracnose is an important post harvest disease which causes heavy loose in quality and economic of papaya. This investigations were carried out in 2018 to 2020 on sustainable management fruit rot of papaya through wrapping materials, botanicals and oil coating of fruit by pre inoculation of pathogens in papaya fruits. The significantly minimum disease intensity after 15 days of the incubation was observed in wrapping papaya fruits with polythene bag 37.78 per cent with 57.50 per cent disease control followed by news paper 46.67 per cent. Among Nine botanical extracts at 10 per cent concentration the minimum disease intensity was observed in garlic extract (28.89%) with 68.29 per cent disease control followed by neem extracts (35.56%) with 60.97 per cent disease control as well as taken 2.83 days for initiation of symptoms. Among eight different oil coatings significantly minimum fruit rot intensity was observed in fruits treated with lemon grass oil (31.11%) and it was at par with mustard oil (33.33%) with 67.44 and 65.12 per cent disease control, respectively.
