Molluscicidal Activity of Plant Derived Molluscicides

ABSTRACT

The essential oils of cedar (Cedrus deodara Roxh.) and neem tree (Azadirachta indica A. Juss.), powder from bulbs of garlic (Allium sativum Linn.), and the oleoresin extracted from rhizomes of ginger (Zingiber officinale Rose.) were mixed in different combinations to test the collective toxicity against the snail Lymnaea (Radix) acuminata Lamark. A mixture of cedar and neem oils were most toxic to Lymnaea acuminata of the combinations tested. Combinations of neem oil with ginger oleoresin or garlic bulb powder was more toxic than the individual components.
