Abstract: One of the most critical pests on rice plants is the brown planthopper (Nilaparvata lugens Stal.), commonly referred to as BPH. BPH can attack rice at all stages of plant growth, and severe infestations can lead to crop failure. Alternatives to control BPH could be achieved by using plant-based pesticides from Zingiber officinale Roscoe in the form of formulations. This study aimed to determine the activity and ability of Z. officinale R botanical insecticide formulation and its economic potential for controlling BPH. The study used a completely randomized design (CRD) with seven treatments and four replications. Z. officinale R. concentrations used were 0.25%, 0.49% 0.70%, 0.98%, 1.38%, treatment using synthetic pesticides, and control. Data were analyzed using variance (ANOVA), and significant differences were further tested with LSD at the 5% level. Data were processed using the Statistical Package for the Social Sciences (SPSS) software. The results showed that the formulation of botanical pesticides from Z. officinale R. could control BPH. Treatment with a concentration of 1.38% was the most effective in killing BPH nymphs by 80%. Application of the Z. officinale R. formulation affected the daily mortality of BPH nymphs. BPH nymphs died in rice 1-4 days after application. Z. officinale R. formulation affected the number of BPH adults formed. The adults formed were 15% at a concentration of 1.38%.
