El documento describe el desarrollo de un nuevo pesticida natural basado en saponinas de quínoa para combatir el caracol de agua dulce Pomacea canaliculata. Los ensayos muestran que las saponinas de quínoa son altamente efectivas para matar caracoles sin dañar peces. Se realizaron pruebas exitosas en Argentina y Filipinas, protegiendo cultivos de arroz. El mecanismo propuesto implica la formación de derivados hidrofóbicos de saponinas que dañan las membranas de los
