GAS exhibits resilience across a broad range of temperatures and displays rapid growth and reproduction rates, contributing to its successful distribution in Malaysia. Consequently, farmers often resort to chemical molluscicides for quick and efficient control. However, the use of these chemicals has adverse effects on human health and the natural ecosystem. The main objective of this study was to evaluate the efficacy of Furcraea spp. raw leaves as a biological molluscicide for managing GAS under both laboratory and field conditions. The study also explored the potential indirect consequences of applying raw leaves from this plant species on non-target organisms which is paddy seedlings and catfish. Additionally, the research quantified the amount of saponin in F. selloa, F. foetida, and F. gigantea. Experiments were conducted both in the laboratory and field condition. In the laboratory, raw leaves of three Furcraea species, F. selloa, F. foetida, and F. gigantea were compared in terms of their optimal quantity and the duration of their molluscicidal properties in controlling GAS. F. gigantea exhibited the most effectiveness in killing GAS, outperforming F. foetida and F. selloa. It took only 24 hours for 27.5 g/L of F. gigantea raw leaves in water to eradicate at least 90% of the GAS population. Moreover, F. gigantea raw leaves could sustain a mortality rate of at least 80% for up to 3 days after application. Subsequently, the impact of F. gigantea raw leaves on paddy seed germination, chlorophyll content, shoot-to-root ratio, plant height, and the survival of catfish were observed. Exposure to F. gigantea raw leaves-soaked water resulted in a reduction in the percentage of paddy seed germination. Although the chlorophyll content increased, the shoot-to-root ratio and height of paddy plants decreased when grown in trays containing F. gigantea raw leaves. Furthermore, more than 50% of the catfish population died when exposed to 30 g/L of F. gigantea raw leaves for 24 hours. Field tests conducted in paddy fields demonstrated that the application of F. gigantea raw leaves resulted in 100% mortality of GAS without affecting catfish survival. Additionally, the application of F. gigantea raw leaves did not impact chlorophyll content or shoot-to-root ratio but enhanced plant height and dry weight compared to synthetic molluscicides. In conclusion, the application of F. gigantea raw leaves in laboratory and paddy fields is effective in killing GAS but alters seed germination and plant traits, and can be harmful to catfish if exposed to high amounts of F. gigantea raw leaves. These findings highlight the efficacy of F. gigantea raw leaves in GAS control and contribute to sustainable paddy management practices. 2024-10-13 uuid:8CC8050D-4340-422D-87B8-2B68B68AA2D9 EFFECTIVENESS OF Furcraea gigantea LEAVES ON GOLDEN APPLE SNAIL, Pomacea canaliculata AND NON-TARGET ORGANISM (MASTER_2024).pdf Thesis |
