Zill and Kent mangoes predisposed to anthracnose (Colletotrichum gloeosporioides) infection were exposed to various packline fungicidal treatments either incorporating benomyl or prochloraz. Following the treatment, the fruit were placed in cold-storage at 12.5 deg C for 28 days. After cold-storage, disease incidence and severity as well as various fruit quality attributes were assessed. All of the treatments incorporating prochloraz showed superior anthracnose control directly after cold-storage. On ripening, hot water dip at 50 deg C for 5 minutes, prochloraz added to the hot water bath (180 ml Omega/100 1 H2O), was the only treatment of those evaluated to result in a significant and marked reduction in disease in both cultivars. This treatment increased surface scald and internal reakdown in Zill but not in Kent. In Kent, it increased the ground skin colouration and total soluble solids content. Hot benomyl treatment (5 mins. at 50 deg C, 200 g Benlate/100 1 H2O) was as effective in controlling anthracnose as was hot water treatment alone (5 mins. at 50 deg C)
