Abstract
Survival of Ralstonia solanacearum, the causal agent of southern bacterial wilt on tomato, in protected cultivation with the absence of tomato crop was determined. The number of bacteria cells was observed, in the debris and soil on TZC medium. The results showed that isolates Rgl, Rg2 and Rg3 of the bacteria were able to survive in plant debris for 9 months under natural conditions. In the laboratory, R solanacearum could be survived for 6 months in the soil under artificial contamination, while it survived for only 3 weeks under field condition. These results indicate that the most important source of inoculum of R. solanacearum for the following season was in plant debris. The debris may protect the bacteria from severe summer conditions.
