Abstrak/Abstract One of the obstaclesin increasing rice production isthe presence of sheathrot pathogen infection,which causes changesin color on the rice sheath to brown or reddish-brown, sometimes does not produce rice grain. Themajorfungal pathogens that cause sheath rot disease are Sarocladium oryzaeand Fusariumspp. The loss of rice yields reaches 85%. The disease found in sixprovinces, some of which are the largest rice-producing centers in Indonesia.A total of twenty-fourSarocladiumsp. were isolated from leaf sheath symptom on potato dextrose agar and water agar medium. Sheath rot pathogenidentification based on molecular method wasperformed using internal transcribed spacer (ITS)rDNAgene sequencing. Necrosis occurs after artificial inoculation in Ciherang rice varietywas observedandshowed that all isolates were pathogenic.Morphological characterization of the isolates identified them as Sarocladiumsp. Molecular identification showed that six representativesisolates belongingto S. oryzae. These findings are important information about the fungal pathogen that causes sheath rot disease in Indonesia, and in studies for formulating control measures of the pathogen inthefuture to prevent the disease epidemic on rice. This is the first report about the existence of sheath rot disease, morphological characterizationand molecular identificationof S. oryzaein various rice fieldsin Indonesia
