Based on organic agriculture and ecological protection considerations, this study used *91201 1 yalung@mail.npust.edu.tw 1
natural plant extracts from Tea Seed Kernel and Sapindus to prevent Pomacea Canaliculata. By usingphvalue as measurement basis; five concentrations including 0.2 g, 1 g, 10 g, 50 gand 100 gon indoor constant temperature test and outdoor exposure test were determined under different temperatures. Result of experiments showed that Tea Seed Kernel is an acidic substance as the dose increases 0.2 gto 100 g, and thephvalue was 4 and 4.5 in indoor constant temperature test and outdoor exposure test; Sapindus rendered weak acid as the dose increases 0.2 gto 100 g, and thephvalue was 5.3 and 6 in indoor constant temperature test and outdoor exposure test. Tea Seed Kernel and Sapindus was positive correlated withphvalue and temperature, both of these substances have significant effectiveness in killing Pomacea Canaliculata. Concerning on environmental impact, Sapindus release weak acid in environment which is less threatening in soil and water, therefore Sapindus which has same effectiveness with Tea Seed Kernel was selected instead of Tea Seed Kernel as substrate to kill the Pomacea Canaliculata in paddy fields.
