Laboratory Evaluation of Organic Compounds as Molluscacides and Ovocides, II

Abstract

A total of 98 compounds were evaluated. Pentachlorophenol, 2,4-dinitro-6-phenylphenol and dinitro-o-cyclohexylphenol gave 100% mortality of lymnaeid snails following 24-hour exposure in concns. of 1 ppm. Fluke ova failed to hatch after an exposure of 24 hours to 2.5 ppm. of Na pentachlorophenate, or to 5 ppm. of dinitro-o-cyclohexylphenol, dicyclohexylamine salt, or Na 2,4,5-trichlorophenate.
