------- R. pseudosolanacearum [phylotype I] (biovar 3) was identified on tomato, eggplant, sweet pepper, Ensete ventricosum. An emerging strain of R. solanacearum , a variant of [phylotype IIB sequevar 4], named [sequevar IIB-4NPB], was not pathogenic to banana. This strain was also found causing bacterial wilt on tomato, Anthurium andreanum, A. ferrierense, Heliconia caribea, cucumber, pumpkin, cataloupe melon, watermelon, Solanum americanum, Pandanus sp. (pandan palm) as well as plantain. Other R. solanacearum [phylotype II] strains found on tomato, potato, Canna indica (purple arrowroot) and Anthurium andreanum included [PIIA-5]. R. solanacearum [phylotypes IIA and IIB-4NPB] strains and R. pseudosolanacearum [phylotype I],were also isolated from river and lake water.

------- The first R. solanacearum [phylotype IIB-4NPB] isolate was obtained from wilted tomato in Fort‐de‐France in 1998. From 1999, it was consistently isolated on wilted Anthurium. In 2001, the first outbreak on cantaloupe (Cucumis melo) was observed in the south‐east (Le Vauclin). A subsequent 2002–03 survey revealed the presence of R. solanacearum [PIIB-4NPB] throughout the south and south‐east of Martinique, in the centre and in the north (leeward and windward sides of the volcano Montagne Pelée). In 2003, one‐third of the isolates recovered from solanaceous hosts, particularly tomato, were R. solanacearum [phylotype IIB-4NPB]. This strain was consistently recovered from wild species and weeds throughout Martinique, including: Xanthosoma sp., Impatiens balsamina, Impatiens hawkerii, Cleome viscosa, Peperomia pellucida, Heliconia caribea, Pandanus sp., Piper dilatatum, Portulaca oleracea and Solanum americanum. R. solanacearum [phylotype IIA] strains were also found on Solanum americanum, Laportea sp. and Urtica dioica and R. pseudosolanacearum [phylotyype I] strains were found on Commelina diffusa, Lilianthus sp., Poa sp. and Solanum torvum.
