Abstract

Nanotechnology is utilized in various fields including agriculture, one of which is in the botanical insecticide formulation. The material used for the formulation of botanical insecticide nano emulsion was tobacco leaf, which was applied to the citrus aphids, Aphis gossypii. This study aimed to determine the effectiveness of botanical insecticide from tobacco leaves in the form of nano emulsion compared to crude extracts. The test was carried out at 4 concentration levels, 0.01%, 0.1%, 1% and 10% and was accompanied by control and two synthetic insecticides in the form of formulation, imidacloprid 0.05% and dimethoate 0.1%. The results showed that nano emulsions were more effective than crude extracts. The effective concentrations were 1% and 10%. The mortality at 1% and 10% concentrations of crude extract were 58% and 100%, while the mortality of nano emulsiuons were 100% and 96% at 48 HAA, respectively. The mortality of nano emulsion was significantly different to the control and not significantly different to the two synthetic insecticides. The LD50 values of crude extract and nano emulsion were 0.73% and 0.14% and the LD90 values were 2.65% and 1.69% at 48 HAA, respectively. Thus, the tobacco botanical insecticide in nanoemulsion form was more effective than the crude extract, so that it could be used as a prospective controlling material against citrus aphids A. gossypii.
