Effects of Palm-Dea Non-Ionic Surfactant as an Additive in Buprofezin Insecticide on the Efficacy of it in Controlling Brown Planthopper Rice Pest

Abstract

Brown planthopper or BPH (Nilaparvata lugens) is still regarded as a major pest in rice cultivation because the damage it causes is quite extensive and almost occurs in every cropping season. The use of pesticide is one of the measures that can be taken to control this pest. In the insecticide formula, surfactant plays a role In increasing the penetration of active compound into the host plant and the target pest and spread it all over the plant tissues. One type of surfactant potential to be used for BPH insecticide applications is diethanolamide (DEA) surfactant. This study was almed at assessing the effects of the use of a non-ionic DEA surfactant made of palm oil methyl ester as an additive in buprofezin insecticide on the efficacy of the insecticide to control BPH pest. Results showed that the addition of non-ionic DEA surfactant gave significant effects on the efficacy of buprofezln in controlling BPH pes t. A probit analysis as part of toxicity test was then done to determine the optimal concentration of non-ionic DEA surfactant to improve the efficacy of Buprofezin insecticide It was shown that the addition of DEA surfactant of 6·/. was the most optimal in improving,; the efficcacy of Buprofezin in insecticide to control BPH" pest.
