There were at least three methods have been applied to control this pest, for
example biologically (Teo 2001; Yusa 2001), mechanically (Wada et al 1999; Takahashi
et al 2002) and chemically. In regard to chemical method, the synthetic pesticides were
commonly used to control freshwater golden apple snail (De la Cruz et al 2001).
However, these pesticides caused resistance to the pests and harmful to the environment
and people. Therefore, some researchers have been studied the alternative pest control
of freshwater golden apple snails (Joshi et al 2008). One of the potential natural product
for freshwater golden apple snail control was Barringtonia racemosa locally known as
penteut ie. According to Musman (2010) the seed extracts of B. racemosa has a
molluscicidal activity to P. canaliculata due to the presence of saponins and flavonoids
which had a significant effect on mortality of the freshwater golden apple snails.
