PatelAbstract 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.

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. |
