Velipillai (1986): R. solanacearum sensu lato widespread on chilli (Capsicum annuum), eggplant (Solanum melongena), tomato (Solanum lycopersicum), and potato (Solanum tuberosum). Biovar 2 was obtained from potato cultivated above 1890 m and in virgin lands in the hill country wet zone; biovar 3 was obtained from tomato and potato in several locations previously cropped with cultivated species in the warmer dry zone; and biovar 2 and3 in the transitional regions between the dry and wet zones. Biovar 4 was found in potatoes grown at Gorandiyatenna (up-country dry zone). Hosts include Anthurin andraeanum from Handessa (mid country), Curcuma domestica (tumeric) and Zingiber officinale (ginger) from Gampaha (low country), Phaseolus vulgaris (bush bean) and Psophocarpus terragonolobus (winged bean) from Gannoruwa (mid eountry), Croton hirtus, Hyptis suaveolens and Sesamum indicum (sesame) from coconut-growing regions in Kurunegala (mid country) and Momordica charantia (bitter gourd) from Marassana (mid country).
