Abstract

Trisnaningsih. 2016. Efficacy and resurgence of brown planthopper (Nilaparvata lugens) with an insecticide formulation of imidacloprid and carbosulfan on rice. Pros Sem Nas Masy Biodiv Indon 2: 81-84. This study aimed to determine the effect of imidacloprid and carbosulfan insecticides against brown planthopper resurgence. The experiment used a completely randomized design with 7 concentration levels i.e. 0 mL/L as control, 0.25 mL/L, 0.50 mL/L, 0.75 mL/L, 1.00 mL/L, 1.50 mL/L and 3.00 mL/L, each was consisted of four replications which conducted according to a standard procedure as described by Pesticide Committee. The results showed that the treatment of insecticides of imidacloprid 100 g/L and carbosulfan 200 g/L at concentrations of 0.25-3.00 mL/L did not cause a resurgence on brown planthopper.
