Fatty compounds including lauryI alcohol and methyl laurate and Tween 20 surfactant (polyoxyethylene [20] sorbitan monolaurate) and Tween 80 surfactant (polyoxyethylene [20] sorbitan monooleate) with 14C-labelling at various positions were used as suckering agents for Maryland, Burley, and bright tobacco types (Nicotiana tabacum L.) and their residues on the tobacco determined. An average residue of 1.61 ppm of fatty compounds and 1.0 ppm of surfactants were found. The combined totaI of 2.6 ppm residue due to these suckering agents is far below an earlier preliminary test of 4.8 ppm of residue in comparison with 7.000 ppm naturally occurring fatty compounds in tobacco.
