Anthracnose is a postharvest disease caused by the fungus Colletotrichum musae that results in major economic losses during transportation and storage of bananas. Mangosteen fruit has been widely used as traditional medicine and also as an antimicrobial agent against plant pathogenic fungi. The effectiveness of mangosteen pericarp crude extract on controlling anthracnose in “Kluai Hom Tong” banana (Musa (AAA group)) was evaluated. The fruits were dipped in various concentrations (0, 1,000, 1,200 and 1,400 mg L-1) of mangosteen pericarp methanol crude extract solution for 2 min and then sprayed with 1 mL of 106 spores mL-1 of Colletotrichum musae. Incubated fruits at 29 ± 2°C for 2 days and stored at 13 ± 2°C for 14 days. Banana fruits were further directly sprayed with 1 mL of 500 mg L-1 of ethephon solution and incubated for one day at room temperature. Anthracnose disease percentage and quality of banana fruits as total soluble solids (TSS), titratable acid (%TA), fresh weight and color were recorded. Color measurements were recorded 2 days interval. The results showed that mangosteen pericarp crude extract treatment demonstrated a lower disease percentage than non-treated fruits and the lowest disease percentage was found in the 1,200 mg L-1 treatment at 45% with 8 days of shelf life.
