Sengon ( Paraserianthes falcataria L. Nielsen) is a plant from the Fabaceae family that has a lot of potentials, both ecologically and economically, to be planted in rehabilitation areas. This study aimed to examine the pathogenicity of the fungus that causes leaf blight on sengon seedlings. The research method includes pathogenicity test activities consisting of field observations, pre-testing, and testing. The study used a Completely Randomized Factorial Design (RALF) and Duncan’s follow-up test. Rhizoctonia sp. has the fastest diameter growth compared to other fungi. Pathogenicity test results can be known that Rhizoctonia sp. produced the highest disease incidence and disease severity and was significantly different from other fungi. Rhizoctonia sp. produces 100% of disease incidence and 87.5% of disease severity. Wound treatment did not show a significant difference. Leaf blight spreads quickly over the entire surface of the sengon leaves, causing leaf fall and seedlings to die.
