Results Obtained in Testing Molluscacides in Field Plots Containing Oncomelania Nosophora, an Intermediate Host of Schistosoma Japonicum

Abstract
Summary 1. Out of 59 chemicals and mixtures tested in the laboratory on O. nosophora, 26 were selected for tests in field plots. 2. Six of these gave encouraging results. They included: calcium cyanamide, sodium dinitro-o-cresol, dinitro-o-cyclohexylphenol, its dicyclohexylamine salt, pentachlorophenol, and sodium pentachlorophenate.
