Molluscicidal Activity of Some Common Spice Plants

Abstract

ABSTRACT Molluscicidal activity of Zingiber officinale rhizome extract, fruits of Trachyspermum ammi, seeds of Trigonella foenum-graecum and Allium cepa bulbs were studied against the snails Lymnaea acuminata and Indoplanorbis exustus. Toxic effect of different preparations and chemicals present in them were also studied against both the snails. It was reported that cineole, citral and oleoresin from ginger rhizome and thymol present in fruits of Trachyspermum ammi were potent molluscicides. Toxic effects of the different preparations and their chemical components were time-as well as dose-dependent.
