The purpose of this research to inhibit the growth of Ralstonia solanacearum bacteria, which is the cause of Wilt in plant using the bacteria at 4.7 × 107 colony forming unit/g soil. The results showed that releasing hot water from 3-holes vertical pipe method could increase efficacy of heat releasing to the soil at the distance of 5 and 10 cm with 40 cm depth of soil. After 240 minutes of hot water releasing, Ralstonia solanacearum was completely inhibited.
