Postharvest decay of cantaloupe caused by Epicoccum nigrum.

A decay causing red discoloration in cantaloupe melons was observed in postharvest storage studies and was occasionally involved in load rejection of melons grown in southeastern Oklahoma, USA. E. nigrum was consistently isolated from areas showing the red discoloration. The fungus was also pathogenic on cucumber, tomato, apple and pear fruit. Comparison of the cantaloupe isolate of E. nigrum with isolates from Pennisetum flaccidum and peas indicated that all were similar if not identical, based on host range and decay characteristics on the previously mentioned fruit. Light and scanning electron microscopy revealed that sporodochia and conidia were typical of E. nigrum. Radial growth was greatest on potato-dextrose agar at 20 deg C and limited at 1, 5 and 30 deg . The fungus remained viable in screw-cap culture tubes of soilless medium (potting mix) for 4 years at c. 20 deg . A proposed common name for the disease is red rot.
