"Evaluation of the tobacco plant as botanical pesticide [1994] - The effectivity of tobacco spray and tobacco leaf dust against insect pests of tomato, cowpea, mungo, eggplant, garlic and corn under field conditions was evaluated. Tobacco aqueous spray was prepared from ground tobacco leaves at 1:10 tobacco: water ratio. Ground tobacco leaves were used as powder dust. Water alone and two standard insecticides, Lannate and Decis, were used as controls. Treatments were applied at 10 days interval. Tobacco spray was effective against beanfly and bean aphid with a population reduction of 89 percent and 97 percent, respectively. Tobacco dust was effective against tomato cutworm and beanfly reducing their populations by 89 percent and 79 percent, respectively. Leafhopper, thrips and corn earworm were reduced by 50-69 percent using either tobacco spray or dust. Corn and tomato yields from plots sprayed with tobacco extracts amd cowpea yield from dusted plots were comparable to those sprayed with the check insecticides." https://agris.fao.org/agris-search/search.do?recordID=PH9610779

"Development of Concentrated Emulsion containing Nicotiana tabacum Extract for Use as Pesticide - Using herbs as an insecticide or pesticide is well known in traditional agriculture. They are biodegradable and also friendly to environment. However, developing of commercial product from herbal plants was limited due to degradation of active ingredients, the variation of active content and there is no standard procedure for quality control. In this research, crude extracts of tobacco leaves (Nicotiana tabacum Linn., Solanaceae) containing nicotine as an active ingredient were studied for developing as concentrated emulsion preparation. Crude tobacco extracts from 95% ethanol were obtained as a brown syrupy mass with strong odors and 19.55% yield. One of the active ingredients, nicotine was selected to be used as a marker in suitable high performance liquid chromatography (HPLC) system in this study. The tobacco extract was stable under acid, base and heat conditions. Therefore, it was selected for further development as a concentrated emulsion formulation. The concentrated emulsion of tobacco extract composed of 10% w/w nicotine was prepared by combining fixed oil (palm oil), emulsifiers (Tween and Span), giving a more physically stable product. Under room temperature and 70 % RH for 6 month, the overall of % amount of nicotine in the product still remained in acceptable level. In the next step, the product was studied in the field with various dilution ratios of water to find out a suitable concentration of product using in agriculture field. It showed that all of the exhausted died and the plants trials are still green and not burned when the dilution is 100 time of its product." https://www.japsonline.com/admin/php/uploads/1101_pdf.pdf

"Between 1537 and 1559, books published in Europe and Mexico commonly referred to the medicinal uses of tobacco among the indigenous populations of the New World, with eyewitness accounts of its therapeutic application in general bodily ills, catarrh, colds, and fevers, as an aid to digestion and in prevention of hunger and thirst, as a purgative and as a narcotic." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1079499/
