Golden snail (Pomacea canliculata L.) is an important pest in rice plants. Synthetic chemical control has many negative impacts such as the occurrence of pest resistance, pest resurgence and environmental pollution. The use of plant molluscicides such as betel nut (Areca catechu L.) is one of alternative pest control to reduce the use of synthetic chemical pesticides. The purpose of this study is to obtain the exact dose of betel nut flour to control golden snails (Pomacea canalicilata L.) in rice plants. The research was conducted at Unit Pelaksana Teknis (UPT) Kebun Percobaan Fakultas Pertanian Universitas Riau by using a completely randomized design with 5 treatments and 4 replications. Treatment consists of betel nut flour dose of 4 g/clump, 5 g/clump, 6 g/clump, 7 g/clump and 8 g/clump. Doses of betel nut flour 8 g/clump able to control golden snail with a total mortality of 87.49%. Appropriate dose to kill 95% golden snail is 1% or the equivalent of 10 g/clump.enRice (Oryza sativa L.)golden Snail (Pomacea canaliculata L.)betel nut (Areca catechu L.)UR-Proceedings
