Abstract

In this study, we evaluated the efficacy of anaerobic soil disinfestation with incorporation of a vegetable oil refining byproduct (VORB) and sugar-containing diatomite (SCD). It was found that incorporation of VORB alone at a dose of 0.4 to 1.0 t/10 a could reduce the soil layer (0–30 cm depth) where VORB had been mixed, thereby disinfecting Ralstonia solanacearum. It was also found that incorporation of SCD at 0.5 t/10 a in combination with VORB at 0.7 t/10 a could effectively reduce the deeper layer (30–50 cm depth) of soil and suppress the development of tomato bacterial wilt.
