Toxicity of Bauhinia variegata and Mimusops elengi with plant molluscicides against Lymnaea acuminata

Abstract

Molluscicidal activity of binary combination of Bauhinia variegata and Mimusops elengi with other plant molluscicides Saraca asoca and Thuja orientalis against snail Lymnaea acuminata have been studied. It was observed that toxicity of binary combinations of plant molluscicides with other plant molluscicides were toxic against fresh water snail L. acuminata. Among all combinations of toxicity Mimusops elengi leaf + Saraca asoca bark (24h LC50: 98.25 mg/l; 96h LC50: 40.40 mg/l) and Bauhinia variegata leaf powder + Saraca asoca leaf (24h LC50: 123.98 mg/l; 96h LC50: 57.91 mg/l) was more toxic than other binary combinations of plant molluscicides. Mimusops elengi leaf powder + Saraca asoca leaf powder and Bauhinia variegata leaf powder + Saraca asoca leaf powder are more potent molluscicides.
