ARS Newslink is reporting that scientists at the Agricultural Research Service, in conjunction with the Philippines Rice Research Institute, have isolated a compound in a species of mugwort (Artemisia douglasiana) that effectively fights both golden apple and ram's horn snails (Pomacea canaliculata and Planorbella trivolvis). Golden apple snails are a major pest in rice paddies, while ram's horn snails carry a parasite that attacks catfish. The compound, "Vulgarone B," is relatively inexpensive and does not appear to affect plants in areas where it has been applied. Bonus points to the ARS for using scientific names.
