    Economic factors influencing lower leaf removal decisions

    BLALOCK C.(1); VANN M.C.(1); FISHER L.R.(1); BROWN A.B.(2)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) North Carolina State University, Department of Agricultural & Economic Resources, Raleigh, NC, U.S.A.
    With a current global over-supply of flue-cured tobacco, tobacco producers in North Carolina have been encouraged to remove the lowermost leaves prior to harvest due to their low value in manufactured products. In field trials, the removal of four or...

    Chloride application: effects to nutrient assimilation, agronomic performance, and cured leaf chemistry of flue-cured tobacco

    VANN M.C.(1); FISHER L.R.(1); INMAN M.D.(1); HARDY D.H.(2)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) North Carolina Department of Agriculture & Consumer Services – Agronomic Division, Raleigh, NC, U.S.A.
    Chloride (Cl-) application in excess of 34 kg ha-1 has generally been discouraged in the production of U.S. flue-cured tobacco, due to the negative effects the nutrient can have on cured leaf yield, quality, and smoke sensory. However, fertilizer...

    Flue-cured tobacco tip leaf yield, quality, value, and color distribution as influenced by cultivar and harvest schedule

    VANN M.C.; FISHER L.R.; INMAN M.D.; WHITLEY D.S.; SEAGROVES R.W.; BARNES K.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Changes in consumer preference and export strategy strongly influence the buying practices of tobacco leaf dealers and cigarette manufacturers. In current times, a dark-colored (orange to red) style of flue-cured tobacco is preferred over a brighter...

    Quantifying dicamba residue in contaminated sprayers

    INMAN M.D.; VANN M.C.; FISHER L.R.; GANNON T.W.; JORDAN D.L.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    The deregulation of dicamba-tolerant cotton and soybean has increased the potential for dicamba exposure to tobacco through drift or tank contamination. Improper cleaning of sprayer equipment and off-target dicamba exposure can have detrimental...

    Field screenings of S-metolachlor for weed suppression in flue-cured tobacco

    CLAPP A.M.; VANN M.C.; FISHER L.R.; INMAN M.D.; SEAGROVES R.W.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    With limited herbicide options and a growing concern to herbicide-resistant weeds, there is a strong need for additional chemical weed control materials in tobacco. S-metolachlor is labeled for use in a variety of agronomic and horticultural crops in...

    Critical period for weed control in flue-cured tobacco

    INMAN M.D.; VANN M.C.; FISHER L.R.; JORDAN D.L.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Field experiments were conducted to determine the critical period for weed control (CPWC) in flue-cured tobacco. This period consists of two separately measured timings; a critical weed-free period and a critical timing for the weed removal period....
