INTRODUCTION
• bacterial wilts of banana – Blood Disease, Moko and Bugtok: caused by members of the Ralstonia solanacearum species complex.
• Ralstonia solanacearum is a heterogeneous species, which has been divided into 4 phylotypes (genetic groups).
• Strains causing Moko and Bugtok belong to phylotype II, the blood disease bacterium belongs to phylotype IV.

• the causative agent of blood disease (BD)
• belongs to phylotype IV of Ralstonia solanacearum species complex
• a widespread and severe wilt disease of banana and plantain in Indonesia – major cause of production decline of banana in Indonesia.
• Spreads very fast – geographical spread of BD ranges from 100 km/yr in Indonesia and 189 – 203 km/yr in Sumatera (Mairawita et al.,2012)

Banana Vascular Wilt in Malaysia
• 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.

Banana Wilt in Johor 2007
• 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.
• Male flowers blackened & shrivelled
• Fruits appeared normal and unaffected but pulp displayed brownish black discolouration & rot 6
banana vascular wilt disease status survey in Johor in 2007 60.7 % of 3,212 ha banana orchards were found to be
infected by banana bacteria wilt (Ralstonia solanacearum/ R.s) and 23.5% were infected by panama disease (Fusarium oxysporum f.sp. cubense/ Foc).
Disease severity varied in different varieties

in 2007 to 2009, banana vascular wilt disease status survey throughout Peninsular Malaysia
- a total of 1,976 ha banana were infected by bacterial wilt R.s,
- 882 ha were infected by Foc and
- 27 ha were infected by both diseases

• banana wilt disease in Johor , N. Sembilan & Malacca
- ProMED mail July 2009: Professor Emeritus Ivan Buddenhagen, University
of California, Davis suggested that BDB may be the possible cause of the
banana disease that appears to be emerging in south-western Malaysia.
However confirmation by molecular methods would be needed for a conclusive
diagnosis.
Banana Vascular Wilt in Malaysia
• In 2012-2013 plants with bacterial wilt symptoms were reported in Negeri Sembilan, Selangor, Penang, Pahang, Johor and Sabah. Infected plants were tested for R. solanacearum spesies complex and BDB using molecular methods.
8th ICPPT 8-10 April 2014 K. Lumpur Malaysia
In 2007- 2009, identification of banana bacterial wilt was done using ooze test and BIOLOG system –BIOLOG identification only to R. solanacearum level thus cannot determine the exact phylotype or race.
13
Laboratory Analysis : Identification of Ralstonia solanacearum species complex
A phylotype multiplex PCR protocol was used to verify the phylotypes of Ralstonia solanacearum species complex and BDB in infected banana samples.
All R. solanacearum strains should produce a band (282 bp) with the 759/760 primers, as well as another band for each of the Phylotypes
I = 144 bp II = 372 bp III = 91 bp IV = 213 bp
The Blood Disease Bacterium (BDB) diagnostic protocol uses the BDB primer set: 121F CGT ATT GGA TGC CGT AAT GGA and 121R AAG TTC ATT GGT GCC GAA TCA – amplifies a 317 bp amplicon from BDB strains.

• Blood disease of banana which previously limited to Indonesia has spread to Peninsular Malaysia and Sabah.
• To the best of our knowledge, this is the first confirmation of Banana Blood Disease in Malaysia.
• Department of Agriculture has developed a Standard of Procedure which stated the action plans and various control measures to mitigate this disease from affecting the banana industry in Malaysia. DOA imposed new import regulation for importation of banana fruits into Malaysia.
