Tobacco Waste

Nilaparvata lugens Stal.is one of plant pest which damages rice field. The waste of tobacco contains nicotine which can use as botanical insecticide. This research was aimed to find out the effectiveness of tobacco waste in controlling brown planthopper and its effect then predator (Oxyopes javanus). The methode of this research applies Completed Randomized Design experiment. In this research, used the kind of tobacco waste and various concentration with triple repeating. The variables of this research were mortality and death period of brown planthopper, mortality and eating capability of O. javanus viewed from direct and indirect application. The concentration 12,5% of tobacco roots extract cause mortality of brown planthopper reaches 93%. Furthermore, the concentration 12,5% of tobacco root extracts made the death period of brown planthopper faster than the other concentrations. Direct application of tobacco waste extracts did not cause of O. javanus. Indirect application of tobacco waste extract did not cause of death toward O. javanus, but caused eating capability of O .javanus. Extract from tobacco bark with concentration 3,125% dan 1,56% had the power repellent which was shown by O. javanus only eat 2,33 brown planthoppers per week.

Characteristics and Toxicity of Nanoemulsion Formulations of Piper retrofractum and Tagetes erecta Extract Mixtures. Nanotechnology has been used in the developing of botanical insecticide formulation for improving its stability and effectiveness. The research was aimed to make nanoemulsion formulations of Piper retrofractum fruits and Tagetes erecta flowers extracts and to evaluate their toxicity against brown planthopper (Nilaparvata lugens [Stål]) nymphs. The development of nanoemulsion formulaions was carried out by using the low energy method with inversion phase emulsification. The toxicity of the four formulations was tested against brown planthopper nymphs using a contact method. Four nanoemulsion formulations were obtained. The study showed that in the developing of the formulations, the type and level of emulsifier materials affected the physical characteristics of formulas, such as stability, surface tension, viscosity, particle size, and particle morphology. The nanoemulsion formulation containing 1% of the mixture of P. retrofractum fruits and T. erecta flowers extracts, 1.75% Triton X-100 emulsifier showed the highest toxic on the brown planthopper nymph, with the LC95 value was 0.15%. The study indicates that nanoemulsion formulation of P. retrofractum and T. erecta extracts are potential to be developed as botanical insecticide to control brown planthopper of rice.

Nilaparvata Lugens Stål

The Brown Planthopper (Nilaparvata lugens Stal.) is one of the pests that often causes rice crop failure in rice. One way to control N. lugens pests is to use of botanical insecticide. The purpose of this experiment is to study the effect of A. cordifolia leaves ethanol in suppressing N. lugens populations. The experiment used a Randomized Block Design (RDB) with 8 treatments and 4 replications. The A. cordifolia leaves ethanol extract concentration tested in this experiment consisted of 0,5%; 0,75%; 1%; 1,5%; and 2%. The results of the experiment showed that the ethanol extract of binahong leaves with a concentration of 1%, 1.5% and 2% cause mortality of N. lugens by 52.50%, 56.25%, and 61.25% on the 14th day after application. Based on the results of this experiment, the ethanol extract of A.cordifolia leaves was not effective against N. lugen.
