    SEMTNER P.J.; WILKINSON III W.B.; REED M.B.
    Virginia Tech, Southern Piedmont Agricultural Research and Extension Center, Blackstone, VA, USA
    Field experiments were conducted in Virginia during 1990-1992 to evaluate the performance of imidacloprid (NTN 33893, Admire) and other experimental and registered insecticides for the control of the tobacco aphid, Myzus nicotianae Blackman, on...

    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...
