In this study, an integrated approach was evaluated for the control of postharvest decays of mandarin including some pre- and post-harvest treatments under storage conditions. The efficacy of the treatments both as alone and in combination was evaluated during 3 years. Preharvest application of benomyl resulted in significantly less decay of mandarin fruit after storage in 3-year tests. Calcium chloride (CaCl2), 2,4-dichlorophenoxyacetic acid (2,4-D) and gibberellic acid (GA(3)) as stand-alone treatments or combinations were not effective in controlling Penicillium and total decay infections on inoculated mandarin. Postharvest application of imazalil (200 mug/ml) in solution heated to 54degreesC for controlling postharvest green and total decay of mandarin was significantly effective for 3 months under storage conditions. The biocontrol activity of yeast (Metschnikowia pulcherrima) was improved when yeast treatment was combined with imazalil (200 mug/ml) at postharvest. The data suggest that preharvest application of benomyl and postharvest treatments of imazalil, hot water and yeast may reduce postharvest green mould and total decay of mandarin under storage conditions.
