Molluscicidal Activity of the Puerto Rican Weed, Solanum nodiflorum, against Snail Hosts of Fasciola hepatica. - Economic Botany, 34(4), p.368-375, 1980 .

After screening 200 species of Puerto Rican plants, Solanum nodiflorum was selected for comprehensive laboratory evaluation as a source of natural molluscicide. All parts of this plant were found toxic to the snails Fossaria (Lymnaea)cubensis, Lymnaea columella, Biomphalaria glabrata, and Physa cubensis. No toxicity was found against Marisa cornuarietis and Tarebia granifera. The toxicant was not affected by pH and dry storage. There was a direct correlation between temperature and molluscicidal activity. The plant is easy to find locally and could be developed into cheap, safe means for controlling both Schistosoma and Fasciola snail hosts in Puerto Rico.
