Abstract
Bacterial wilt disease in banana plants caused by Ralstonia solanacearum is an important disease that can reduce banana production. Until now there is no effective method to control this disease. The use of biocontrol agents such as Bacillus spp is an alternative method of controlling R. solanacearum in bananas. The aim of this study was to determine the activity of Bacillus spp against banana wilt disease caused by R. solanacearum. In vitro testing was carried out in the Plant Physiology Laboratory, Faculty of Agriculture, Pattimura University. The study used Bacillus subtilis strain SW116b and Bacillus subtilis strain HPC2-1 isolates. The results showed that the SW116b stain Bacillus subtilis has the highest activity against R. solanocearum, which is 10.5mm, so it has the potential as a biological control agent in suppressing the development of ralstonia wilt disease in bananas.
