Abstract


ABSTRACT
Pathogenicity of banana wilt  bacteria (Ralstonia sp.) on  several other  plants.  This experiment was conducted to investigate the pathogenicity of bacterial wilt of banana pathogen (Ralstonia sp.) isolated from infected plants in Lampung on tomato, chili pepper, eggplant, and ginger.  The experiment was conducted in Laboratory of Plant Protection Department,  Faculty of Agricultural University of Lampung, from May 1999 to February 2000.  Treatments in this experiment were arranged in a completely randomized design with four replications. The treatments were tomato, eggplant, chili pepper, and  ginger.  Banana was used as the control. The results of this experiment showed that up to 30 days after inoculation, the bacteria isolated from banana found  in Lampung was not able to cause symptom on tomato,  chili pepper, eggplant, nor ginger. However, this bacteria caused wilting on banana eight days after inoculation; the incubation period of this bacteria on banana was eight days.
