Abstract

Effectiveness study of BPMC insecticide and suren leaf extract esticide against brown planthopper and its side-effect on its natural enemy population on paddy Ciherang variety was conducted in rice field of Balai Besar Peramalan Organisme Pengganggu Tumbuhan (BBPOPT), Karawang, West Java from May to August 2015. The experimental design used was Randomized Blok Design with 7 treatments and 4 replications ie suren leaf extract of 50 g/l, 100 g/l and 150 g/l, three concentrations of BPMC of 0.5 ml/l, 1.0 ml/l and 1.5 ml/l, and a control treatment. The results showed that BPMC insecticide and suren leaf extract were able to suppress the population of brown planthopper and influenced its natural enemy population. The treatment of 50 g/l suren leaf extract gave the highest suppression of the brown planthopper population. It was also caused no negative impact to the natural enemies of P. fuscipes and L. pseudoannulata. The application of 1.5 ml/l of BPMC insecticide gave the highest grain weight average of 37.80 kg/plot compared to the lowest production in control treatment of 32.63 kg/plot. Therefore, application of BPMC insecticide and suren leaf extract effectively suppressed the brown planthopper population and the natural enemy existence was assumed to affect the rice grain production in this study.
