Molluscicides potential of Acacia mangium (Willd.) and Gliricidia sepium (Jacq.) against Pomacea canaliculata (Lamark) / Muhammad Mu'izzuddin Zulkapli

Golden Apple Snails or scientifically known as Pomacea canaliculata (Lamark) is still one of the major problems faced by paddy farmers. Both conventional chemical molluscicides and bio-molluscicides have been used to control the population of this pest. However, the current bio-molluscicides are costly and not suitable for mass production. In this study, two species of fast growing plants that are commonly can be found in Malaysia were tested for their potential molluscicidal activity against Pomacea canaliculata (Lamark). It was found that both selected plants are showing a positive molluscicidal activity against this pest. Additionally, this study found that there was no significant difference in the 24 hours mortality recorded of Pomacea canaliculata (Lamark) between the current practical bio-molluscicide that is Furcraea selloa var. marginata (Trel.) and Acacia mangium (Willd.). Study also had identified the LD50 of each plant at 24g for Furcraea selloa var. marginata (Trel.), 25g for Acacia mangium (Willd.) and 30g for Gliricidia sepium (Jacq.). More research and development should be done to highlight the potential of Acacia mangium (Willd.) as bio-molluscicide.
