Six plant species belonging to Araceae and one species of Solanaceae were infested with taro feathery mosaic disease Typhonium trilobatum (Linn) Schott, Dieffenbachia maculata, Dieffenbachia sp. and Datura metel Blanco were highly susceptible while Xanthomonas sp. was moderately susceptible. Caladium bicolor (Avit.) Vent showed stunting and leaf distortion while Cyrtosperna merkussii (Linn). Schott was the only species which showed latent infection. Dieffenbachia spp. had an average incubation period of 4.5 days followed by D. metel with 7.8 days; T. trilobatum, 13.5 days; Xanthosoma sp., 14.4 days; C. bicolor, 17.6 days and C. merkusii, 14 days. Back-inoculation of taro showed the positive presence of taro mosaic in these plants
