Abstrak

The research was carried out it the Greenhouse of the Faculty of Agriculture, Nusa Cendana University, East Nusa Tenggara from July 2020 to August 2020. The purpose of this study was to determine the effectiveness of several types of botanical molluscicides, namely areca nut, tobacco, and neem against golden snails in rice plants. This study was laid out in a completely randomized design (CRD) with 3 treatments and each treatment was repeated 4 times. The results showed that the observed symptoms of mortality in gold snails treated with tobacco leaf extract showed symptoms of the color of the golden snail skin turning pale, slower movement, and then death Tobacco leaf extract is toxic to golden snails which at a concentration of 20% it could kill 100% golden snails. The results of probit analysis showed that tobacco leaf extract was the most toxic botanical molluscicide tested on golden snails. At a concentration of 1.19% tobacco leaf extract could kill 50% of golden snails (LC50). While at the same LC, the concentrations required by neem and areca nut were 3.15% and 5.58%, respectively. The LC95 value showed that tobacco leaf extract was 12.87 times more toxic than neem leaf extract and 8.06 times more toxic than areca nut extract. Meanwhile, areca nut extract was 0.62 times more toxic than neem leaf extract. Thus, tobacco leaf extract can be used as a molucuside and is recommended to control golden snails.
