Some studies on postharvest fungal diseases of mango, Mangifera indica L. and their control.

Different markets of Hyderabad, Mirpurkhas, Tandojam and Tando Allahyar were surveyed to record the prevalence of mango fruit rots. Botryodiplodia theobromae was predominantly isolated from rotted mangoes followed by Aspergillus niger, Rhizopus nigricans [R. stolonifer] and Penicillium spp. B. theobromae produced typical symptoms on cultivars Lungra and Chausa within 3-4 days after inoculation compared to cultivars Sindhri, Neelam and Desi. Skin injury level and size of rotting caused by the fungus were significantly higher on Lungra followed by Chausa. The time of ripening of Lungra and Chausa after inoculation was the highest unlike in Desi which was significantly reduced. Rotting on all cultivars was significantly inhibited when the fruits were dipped in hot water at 55 deg C, followed by 50 deg C for 5 minutes before inoculation. Benlate [benomyl] significantly reduced the growth of B. theobromae colony at its respective rates compared to Rizolex [toclofos-methyl], Dithane M 45 [mancozeb], Cupravit [copper oxychloride] and control.
