Abstract
The golden apple snail (Pomacea canaliculata) is a significant pest in rice fields, with its prolific egg-laying contributing to rapid population growth and substantial crop damage. This study investigates the ovicidal potential of Magnolia sumatrana var. glauca leaf extract as an eco-friendly method for controlling P. canaliculata populations by targeting its eggs. The experiment employed a randomized complete design (RCD) with seven treatments and five replicates, testing leaf extract concentrations as follows: F0 (positive control - chemical agent), F1 (negative control), F2 (6% extract), F3 (8% extract), F4 (10% extract), F5 (12% extract), and F6 (14% extract). Egg clusters were treated in laboratory conditions, and observations were conducted over a 14-day period to assess egg viability, mortality rates, and structural changes in the eggshell. Data analysis was conducted using ANOVA. The results indicated that application of M. sumatrana leaf ethanol extract at 12% and 14% effectively inhibited egg hatching by 100%, reducing the hatching rate to 0% and preventing hatching for up to 14 days post-treatment.The results indicate that M. sumatrana leaf extract has potent ovicidal effects, highlighting its potential as a sustainable alternative for controlling golden apple snail populations. Further research is recommended to assess its broader applications and impact on non-target species in agricultural ecosystems.
