ABSTRACT: Anthracnose of chili caused by Colletotrichum capsici is responsible for huge yield loss in Bangladesh. To avoid chemical control of the disease, the present study was aimed to observe the field efficacy of selected medicinal plants including neem (Azadirachta indica) and mahogany (Swietenia mahagoni) and a commercially available formulated Trichoderma either alone or in various combinations. Among all the treatments, combined application of mahogany leaf extract and peat soil-based Trichoderma resulted highest reduction of disease incidence (58.99%) and severity (67.19%) of the leaf over control. Similar treatment combinations also resulted the highest reduction of diseaseincidence (64.08%) and severity (68.97%)of fruit over control. The combined application of mahogany leaf extractand peat soil-based Trichoderma alsoexhibited the highestplant height (27.44cm), number of fruits per plant (169), and fruit weight per plant (499.10g). The findingsof the present study exploredthe potentiality of the combined application of mahogany leaf extract and peat soil-based Trichoderma for the eco-friendly management of Anthracnose of chili.
