Brazil is one of the world eucalyptus producers. With o increased planting of this crop in the country many diseases that were not previously reported has been causing problems. Among the phytopathogenic microorganisms which has caused losses in this segment are bacteria. One of the bacteria that has gained repercussion on the problems caused is Ralstonia solanacearum. This bacterium develops in plant pots causing wilt and dry. Faced with this problem the study aimed to survey the incidence R. solanacearum in samples received in Forest Pathology Clinic of UNESP / Botucatu. Samples of plants, water and soil were analyzed. The bacteria were isolated in the middle of Kelman culture, collected after their development and their DNA was extracted for detection by amplification via specific oligonucleotide. The analyzes were detected 20.64, 6.25 and 14.31% incidence of the disease in the samples received from plants, water and soil, respectively. Since there are no chemicals to control this bacterium and before the results it is clear there is a need of taking some control measures such as use of healthy seedlings and sanitizing the work environment.
