Purpose: Solanum melongena L. (brinjal/ eggplant) is a popular vegetable in Sri Lanka. Like many solanaceous crops, brinjal fruits and plants are susceptible to various diseases. The objective of this study was isolate, confirm pathogenicity characterize fungal pathogens causing leaf blight, yellowing necrosis S. selected localities Gampaha district, Research Method: Fungi associated with symptomatic collected from three Lanka, were isolated onto potato dextrose agar their tested on healthy plants. Fungal isolates that confirmed be pathogenic subjected morphological molecular characterization. Findings: Fifteen obtained infected leaves plants, four melongena. Isolates H32a H32b similar disease symptoms identified as Lasiodiplodia theobromae 99.81% sequence similarity by the analysis internal transcribed spacer region (ITS1-5.8S-ITS2). remaining two Pseudopestalotiopsis theae Diaporthe eugeniae, 100% 99.82% similarities, respectively. Originality/ Value: To our knowledge, first report theobromae, P. blight D. eugeniae
