Summary : Bacterial wilt caused by Ralstonia solanacearum is one of the most important bacterial disease on cash crops in tropical and subtropical areas; R. solanacearum has a very wide host range and attacks a high number of crops which have important/high economic value such as potato, tomato, eggplant, pepper, ginger, legumes and banana. Fifteen isolates of R. solanacearum from several solanaceous plants in Yogyakarta had bacteriological characteristics like those described by HAyward (1976), He et al, (1983), Drior and Steva (1990) and Hayward (1994). Of the 15 isolates, 13 were biovar III, two other isolates, could not be grouped into biovar. Host range test with three most virulent isolate showed that the isolate was Race 1. most Yogyakarta isolates of R. solanacearum (13 of 15 isolates) were capable of producing bacteriosin on CPG medium with different growth inhibition spectrum. All isolates were susceptible to Agrimycin 45 ppm. The minimum concentration of R. solanacearum that can cause disease were 10 cfu/ml on wounded roots and 10 cfu/ml on unwounded roots.
