Sengon (Paraserianthes falcataria (L.) Nielsen) is a major forest tree species that is widely planted by smallholders in Indonesia. Ganodema infection as red root-rot or basal stem rot is becoming a more prevalent disease causing significant tree death. This research investigates the potential of biological control agents to protect Sengon seedlings from Ganoderma attacks. In vitro tests for antagonism between two Trichoderma spp (DT38 and DT39) and five fungal isolates of Ganoderma on PDA were undertaken. Four treatments were applied to sengon seedlings: 1) without Trichoderma + without organic materials (A0B0); 2) without Trichoderma + organic materials (A0B1); 3) Trichoderma + without organic materials materials (A1B0); 4) with Trichoderma + organic materials (A1B1). Seedling height and the number of leaves was recorded.
