Bacterial leaf blight is the most important rice disease in Indonesia and other rice producing countries in Asia. Bacterial leaf blight disease, caused by the bacterial pathogen Xanthomonas oryzae pv oryzae , has a wide distribution in the tropics and sub-tropics. This research was aimed to determine the distribution of the disease in North Sumatera. The research experiment was conducted using the survey method to calculate the incidence and severity of disease in rice crops in seven locations. The highest disease incidence was found in Sumber Tani Village, Batubara District, and in Talawi Siabal Abal Village, Sipahutar District of North Tapanuli with a disease incidence of 100%. The highest percentage of disease severity was found in Siabal Abal Village, Sipahutar District of North Tapanuli, with a percentage of 82% severity.
