    Laboratory assays for evaluation of products for control of pole rot of tobacco caused by Rhizopus arrhizus

    REELEDER R.D.
    Agric. Canada Res. Station, Delhi, Ontario, Canada
    Procedures for the rapid screening of chemical products for control of pole rot of tobacco were developed. A leaf disk assay was developed using disks cut from mature leaves selected from greenhouse-grown plants ( Delgold ). Leaf disks were placed in...

    Collection and ion chromatographic determination of nitrous acid in air

    RISNER C.H.
    R.J. Reynolds Tobacco Company, Bowman Gray Technical Center, Winston-Salem, NC, USA
    An active sampling method based on a solid-phase collection medium was used to determine nitrous acid concentrations in indoor air. A carbonate-bicarbonate coated filter was found to be inefficient for collection of nitrous acid. An amino type, weak...

    Development of a theoretical model to predict the efficiency of flavor adsorption for tobacco cut-filler

    NAKANISHI Y.
    Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan.
    Historically, processes for the application of volatile flavors to tobacco cut-filler materials has depended solely on an adsorption process. Results from the author's study, employing both theoretical and empirical approaches, have indicated that...
