Abstract : The study was conducted at the Regional Horticulture Research Station, Bangladesh Agricultural Research Institute (BARI), Chapai Nawabganj, Bangladesh during February to June, 2010 to test the efficacy of nine available indigenous plant extracts eg. Onion, Garlic, Ginger, Tulsi, Neem, Dalim, Arjun, Marigold, and Biskathali against post-harvest anthracnose and stem-end rot of mango. The selected plant extracts were spayed to the mango (Mangifera indica L.) trees during fruit developing stage. The effect of the plant extracts were evaluated on the ripening fruits. None of the plant extracts under investigation was able to control both the disease completely. Among them, extracts collected from ginger rhizome performed the best (85.19%) in controlling post harvest anthracnose followed by extracts of Tulsi (Occimum sanctum) (83.96%) and Dalim (Punica granatum) (83.96%) leaves which is statistically identical with the fungicides Pencozeb 80 WP (mancozeb) used as standard check which controlled more than 80 percent of the disease. On the other hand, extract of Tulsi leaves was the best (14.28%) for controlling stem-end rot of mango followed by ginger (28.57%).
