Bacterial wilt caused by Ralstonia solanacearum is one of major diseases on tobacco worldwide. This research aimed to determine the distribution of bacterial wilt disease on tobacco plantation in Temanggung District, Central Java. Observation of the incidence of bacterial wilt disease was carried out on 53 sampling areas determined based on land system. The observation was conducted on two-month old tobacco in the field. At the same time, soil samples were collected for detection of bacterial population. The last activity was carried out three different times i.e. before, when, and after tobacco planting in the field. The results revealed that the incidence of bacterial wilt diseases ranged from 0-28% which means that the distribution of bacterial wilt across tobacco plantation was categorized from very low to moderate. The highest incidence of bacterial wilt was found in sampling point 23 located in Tegalurung, Bulu. We also found zero incidence of bacterial wilt in thirteen locations. The population of bacteria was determined in 11 sampling locations which are generally known as “lahan lincat”. The results showed that the highest population was reached at after planting time followed by when and before planting, they were 3.67-80.67×10 4 , 0-10.67 ×10 4 and 0-1 ×10 4 cfu/g soil, respectively.
