The study was carried out at Sabah Tea Plantation which is located at 20 km from Ranau at Kampung Nalapak, Sabah. The study is to identify the causal agent of the root rot disease occurring at Sabah Tea. 14 root samples of infected tea trees, believed to have died of Poria disease were col1ected. Whereby, 7 root samples were taken from a field under conventional farming practice and 7 from a field under organic farming practice. Extraction of pathogens was carried out by surface sterilization and subsequent culturing on PDA. Out of the 14 root samples, funguses were successfully extracted from 9 samples, whereby 4 different types were found. Based on microscopic examination the causal agent of the disease attacked could not be confirmed. It was therefore concluded that the disease at Sabah Tea was not caused by Poria Hypolateritia. Instead it is suggested that it is a brown root rot, caused by the fungus Fomes noxius.
