Anthracnose caused by Colletotrichum gloeosporioides is the most prevalent postharvest disease of papaya that results in major economic losses. To investigate the effect of ethanolic extract of propolis (EEP) alone or in combination with gum arabic (GA) on control of postharvest anthracnoase and maintenance of fruit quality during storage, papaya fruit treated with 0.5, 1.0 and 1.5% EEP alone or in combination with 10% GA were stored at 13 ± 1°C and 80-90% RH for 28 days. Data regarding antifungal assays and fruit quality were taken at 7 days intervals. Fruit treated with 1.5% EEP exhibited highest (87%) reduction in mycelial growth. Application of EEP delayed the development of postharvest anthracnose and maintained quality of papaya fruit. Combine application of 1.5% EEP and 10% GA composite coating synergistically reduced the occurrence of antracnose and delayed the reduction of weight loss, fruit firmness, soluble solids concentration and titratable acidity in papaya fruit as compared to all other treatments and control. The results suggest that combine application of 1.5% EEP and 10% GA can be used effectively as a biofungicide for controlling postharvest anthracnose as well as maintaining quality of papaya fruit. © 2013 Friends Science Publishers
