Abstract : Treatment with hot water at 55 deg C controlled mango anthracnose (Colletotrichum gloeosporioides var. minor) during storage for 11 days at 25 deg . The addition of benomyl at 500 or 1000 mu g/ml allowed the treatment temperature to be reduced to 51.5 deg and 48.5 deg , respectively, without reducing efficacy. The rate of change in background skin colour from green to yellow increased as the dipping temperature increased. Mineral oil and hydrochloric acid added to benomyl at room temperature failed to improve anthracnose control significantly. Treatment at 51.5 deg with 500 mu g/ml benomyl was selected for semi-commercial testing.
