Summary

In 2007, outbreaks of banana wilt and fruit rot symptoms were observed in many banana plantations in the state of Johor, Malaysia. The outbreaks of this disease were reported after the December 2006/January 2007 massive flood incidents in Johor. Symptoms consisted of yellowing , wilting and necrosis of leaves, followed by death of the whole plant. Bacterial ooze exuded from the cut surface of infected pseudostems and fruits. In 2012-2013, a Phylotype-specific multiplex PCR was used to verify the phylotypes of Ralstonia solanacearum species complex and BDB in infected banana samples. Infected banana samples from Johor, Negeri Sembilan, Selangor, Penang and Sabah were found to be infected by R. solanacearum species complex (R. solanacearum phylotype IV and BDB).
