------- R. solanacearum [phylotype II] and R. pseudosolanacearum [phylotypes I and III] widespread and co-occur throughout the potato growing basins in the Malagasy Central Highlands. Phylotypes [PI-18] and [PI-33], [PIIB-1], [PIII-19], [PIII-58], [PIII-59] and [PIII-60] isolated from potato in Madagascar. [Phylotypes IIB-1 and III] found in the highlands, whereas [phylotypes I and III] found in the plains. Other hosts from which R. solanacearum [phylotype IIB-1] was isolated include tomato, Bidens pilosa and Phaseolus vulgaris. This is the first report of the [PIIB-1] strain in Madagascar, responsible for several epidemics in potato in 2009.
