Abstract

This study dealt on the efficacy of Kae farang(Gliciridia sepium) and Siam Weed (Chromolaena odorata) leaves extract as organic molluscicide on the Golden snail. Qualitative phytochemical analysis of Glicridia sepium and Chromolaena odorata was done and it showed that there are alkaloids, polyphenols/ tannins, steroids , cyanidin, saponins, and deoxysugars present in the extracts. Phytochemical screening of metabolites was done using the protocols of Guevara, et al. The study used in vitro trials using one (1) liter plastic containers with three(3) replications. Water (T0) from the field where the snails were collected, the aqueous extract of Gliciridia (T1) and Chromolaena (T2)were the treatments in this study. The snails were set in 10 mL water from the source and allowed to be active for overnight to ensure that they are alive. Ten (10) mL of pure extracts were applied to each of the treatments. The snail behavior was observed and noted for every 30 minutes until three hours. After three hours, the mortality rate of the snails was noted. It showed that 100 % of the snails died in the two plant extracts. There were no dead snails in the control treatment (water from the field). In conclusion, kae farang and siam weed extracts are effective as a molluscicide in the in vitro trials. It is therefore recommended that a field study should be done to further test the efficacy of the leaf extracts of both plants on Golden snail. Furthermore, the following studies are recommended: comparison of fresh and dried leaf extracts be done, stored extracts may also be tested compared to extracts fermented for twenty-four ( 24) hours. It is further recommended that Chromolaena extracts will undergo quantitative phytochemical analysis for nitrogen content because of its potential as a fertilizer.
