    Evaluation of flue-cured tobacco breeding lines for improved sucker control with maleic hydrazide

    SELTMANN H.; SISSON V.A.
    USDA-ARS, Crops Research Lab, Oxford, NC, USA
    Residues of maleic hydrazide (MH) used to control suckers (axillary buds) in the production of flue-cured tobacco (Nicotiana tabacum L.) pose a problem in the marketability of the cured leaf. This study was conducted to determine if sucker control...

    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...

    JACKSON D.M.; GWYNN G.R.
    USDA-ARS, Crops Research Lab, Oxford, NC, USA
    Twelve insecticides in various formulations and application procedures were evaluated for control of tobacco budworm larvae on inflorescences and seed pods of flue-cured tobacco in nurseries for seed production. Backpack spray applications of...
