| Summary: | Nowadays synthetic molluscicides were used to kill adult form of snails and the substance was not design specifically to kill dormant stage of Pomacea canaliculata. Pomacea canaliculata also known as golden apple snails that can be found throughout the world. It was very serious pest towards agricultural such as paddy fields. The purposes of the study is to determine which molluscicides is more effective towards the eggs of golden apple snail and the effective concentration to inhibit the eggs. By using spot spraying method, the collected eggs were sprayed by Metaldehyde and Niclosamide with five different concentration. The amount of concentration tested was obtained from recommended rates by the farmers. From the research, it was found that Niclosamide is a better molluscicides compared to Metaldehyde in all concentration. All the concentration tested have significant effect towards the hatchability process but there was no effective concentration was found since there was no concentration is successfully inhibit more than 75% hatching process. This was due to protective covering of the eggs and the concentration used was still in low concentration. The concentration used was not yet effective, but it have the potential to become more effective with the right amount of concentration applied. |
