Abstract
This study was conducted to determine the molluscicidal property of Euphorbia milii L. leaves using indigenous solvent, lambanog and vinegar against young and adult golden apple snails (Pomacea canaliculata L.) A phytochemical screening was performed to know the phytochemicals present in the plant. The E. milii leaves extract showed molluscicidal activity against golden snail. The indigenous extracts was subjected to bioassay for the determination of the mortality at 24, 48 and 72 hours after exposure to the extract treatment. The percent mortality of the golden apple snails in the positive control was consistently high. The indigenous extract of E. milii leaves using lambanog were effective and at the last (72) hours can kill almost 70% and E. milii leaves using vinegar can kill 60% of golden apple snails. The highest mortality were obtained in 1000 ppm for both indigenous (lambanog and vinegar) extracts of E. milii leaves and results showed that the lambanog extract is more effective in killing golden apple snails than of the vinegar extracts. Results proves that leaves of E. milii leaves can kill both young and adult golden apple snails and also the lambanog ang vinegar is an effective solvent in killing golden apple snails. The study provides considerable scope in locating indigenous solvents for snails molluscicidal agents and E. milii leaves is potential source of natural molluscicide.
