Tomato bacterial wilt caused by Ralstonia solanacearum is one of the most destructive soilborne
diseases. Many strategies have been taken to improve soil suppressiveness against
this destructive disease, but limited success has been achieved. In this study, a novel bioorganic
fertilizer revealed a higher suppressive ability against bacterial wilt compared with
several soil management methods in the field over four growing seasons from March 2011
to July 2013. The application of the bioorganic fertilizer significantly (P
