cause mortality to golden apple snail within 6.56 to 10.11
minutes. Assay of combined extracts against giant earthworm also showed significant differences on
mortality time and falls within 11 to 19 minutes. Mortality time for both golden kuhol and giant
earthworm decreases as dosage increases. Field trials on efficacy of combined extracts showed 100%
mortality of Pomacea canaliculata and Pheretima sp. after 24 hours. The study demonstrated that
combined crude extracts of Sandoricum vidalii fruit and barks of Harpulia arborea and Parkia sp. are
effective organic pesticide particularly molluscicide/vermicide that effectively control golden apple snail
(Pomacea canaliculata) and giant earthworms (Pheretima sp).
