Penggunaan Beberapa Konsentrasi Ekstrak Umbi Gadung (Dioscorea Hispida Dennst) Dalam Mengendalikan Hama Walang Sangit (Leptocorisa Acuta T.) Pada Tanaman Padi Gogo (Oryza Sativa L.) Di Lapangan

Food needs rice production (Oryza sativa L.) in Riau Province was lower than the previous year. One of the main constraints of upland rice is one of which is rice bug pest attack (Leptocorisa acuta T.). Eco-friendly pest controls are offered using pestiside botanical of gadung tuber extract (Dioscorea hispida Dennst). The aim of the study was to obtain the concentration of gadung tuber extract which was effective in controlling the rice seed bug pest on upland rice plants in the field. The research has been implemented in the experimental garden (green house), Faculty of Agriculture, University of Riau which from January to April 2018. The research is prepared using a completely randomized design (CRD) with 5 treatments and 4 repeat, ie the concentration of gadung tuber extract 80 g.l-1 water, 85 g.l-1 water, 90 g.l-1 water, 95 g.l-1 water, and 100 g.l-1 water. The observed parameters are, morphology changes and behavior, the start time of the death (hours), lethal time 50 (hours), daily mortality (%), total mortality (%), temperature and humidity. The results showed that the concentration of 90 g.l-1 water was an effective concentration for controlling rice bug pest control with an initial death time of 3.50 hours, LT50 at 15.25 hours after application and a total mortality of 85%.
Keywords: Rice plants (Oryza sativa L.), Rice seed bug pest (Leptocorisa acuta T.), Botanical pesticides, Gadung tuber extract (Dioscorea hispida Dennst.
