Abstract
This study was conudcted to evaluate the molluscidal property of ethanolic extract of Euphorbia pulcherrima Willd. against young and adult golden apple snails (Pomacea canaliculata L.) and to determine the phytochemical composition of the plant extract used. The ethanolic extracts was subjected to bioassay using spray method for the determination of the golden apple snail mortality rate after 24, 48 and 72 hours of exposure to different treatments.
The results show that E. pulcherrima Willd. plant extract can be a potential source of plant molluscicide. Statistical analysis shows that 24-72 hours of exposureto 1000ppm of the plant extract has the highest mortality and is the best treatment for both young and adult golden apple snails among plant extract.
Moreover, molluscicidal property of E. pulcherrima Willd. plant extract can be associated with the present bioactive compounds saponins, tannins, cardiac gycosides and coumrin. However, phlobatannins, flavonoids, alkaloids and terpenoids were absent.
The effectiveness of ethanolic extracts was evident in all treated golden apple snails. The ethanolic extract of E. pulcherrima Willd. plant studied is potential source of natural molluscicide.
