Research ArticleOpen accessIn the abstractMolluscicidal Activity of Ethanolic Dieffenbachia seguine (Dumb Cane) Leaf Extract Against Pomacea canaliculata (Golden Apple Snail)Alfredo V. Corpuz, Carmela M. Florentino, Ace Danielle C. Avero, Sherwin V. AlvaroThe golden apple snail (Pomacea canaliculata), an invasive species that originated in South America, has caused significant damage to rice plantations in Southeast Asia, notably the Philippines. Because of its voracious appetite for aquatic vegetation and quick reproduction rate, it poses a significant agricultural problem. Conventional control approaches, which mostly use chemical molluscicides, have increased environmental issues and threats to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 14 Sep 2026 · 860 accessesView PDFCite
