Abstract

Summary

An immersion test for screening chemicals for molluscicidal activity against snails and a modification of the McMullen plate test are described. Results of screening 89 compounds by these methods are given. Twenty-four compounds had an LD of less than 0.1 mg (5 ppm) by the immersion test and 0.2 mg (100 ppm) by the plate test. Sodium pentachlorophenate and dinitro-o-cyclohexylphenol were control chemicals. It is believed that the immersion test eliminates several variables inherent in the plate test and that it is preferable for screening of molluscicides in the laboratory.
