Ten weeds/wild plants belonging to six families, viz. Martynia annua, Cleome viscosa, Physalis minima, Cestrum diurnum, Amaranthus spinosus, Costus speciosus, Croton sparsiflorus, Datura metel, Solanum indicum and Solanum sisymbriifolium were recorded as the host plants of Ralstonia solanacearum from Sundanban region of West Bengal, India. Among them, Martynia annua and Cleome viscose were recorded first time from India. These weed hosts enable the survival of the bacterial pathogen in absence of crop hosts, and play a significant role in widespread incidence of bacterial wilt of cultivated vegetable crops in West Bengal.
