Bacterial wilt of jute, a newly found disease, was found occurring in some fields' in central Taiwan. Symptoms of the disease were wilting of plants and brownish discoloration of the vascular tissue. Based on cultural characteristics, physiological and biochemical properties, Biolog System and pathogenecity test, the causal organism was identified as Ralstonia solanacearum. All isolates obtained in this study were race 1and biovar 4. The pathogen could induce wilting not only on jute but also on other solanaceous plants. Through wounds, stem inoculation of jute with R. solanacearum produced 86.7% of disease incidence, but root dipping inoculation induced only disease incidence of 26.7%.
