Abstract: This study aimed to isolate and identify the pathogens responsible for root and stem rot disease in durian trees within the rhizosphere zone. Samples were collected from trees exhibiting symptoms of root and stem rot, as well as from affected fruits and stem barks in growing area of the lower northern region, specifically Uttaradit and Sukhothai provinces. Morphological and molecular methods were employed to identify the causative agent of durian root and stem rot. A total of 21 fungal isolates were obtained using baiting and tissue transplanting techniques, comprising 16 isolates from soil and 5 isolates from infected stem barks and fruits. Upon inoculation onto healthy durian leaves, 9 fungal isolates demonstrated pathogenicity. Through morphological characterization and analysis of the ITS-nrDNA Region, four species of the fungi and organisms resembling fungi were identified as Phytophthora palmivora, Pythium splendens, Fusarium solani and Mortierella chlamydospora
