    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Tobacco seedlings from 16 different outdoor seedbeds in 11 counties in Georgia were assayed by ELISA for tomato spotted wilt virus (TSWV). Only one asymptomatic seedling out of more than 1,200 was positive for TSWV. Additional seedlings from the 16...

    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...

    Evaluation of an enzyme-linked immunosorbent assay for Phytophthora parasitica var. nicotianae in tobacco

    CSINOS A.S.; MILLER S.
    University of Georgia, Dept. of Plant Pathology, Coastal Plain Experimental Station, Tifton, GA, USA
    Diseased tobacco (Nicotiana tabacum L.) samples collected from a black shank nursery or commercial fields in 1988 and 1989 were used to compare enzyme-linked immunosorbent assay (ELISA) Phytophthora kits to standard culture plating identification...

    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...
