    Evaluations of rimsulfuron application timing and rate in flue-cured tobacco

    VANN M.C.; INMAN M.D.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Field studies were conducted from 2016 through 2018 to evaluate flue-cured tobacco response to rimsulfuron application timing and rate (17 and 34 g a.i. ha-1). Additionally, weed control was evaluated in combination with current recommended herbicide...

    Cured leaf residues following applications of fluopicolide, indoxacarb, and oxathiapiprolin to flue-cured tobacco

    VANN M.C.; INMAN M.D.; WHITLEY D.S.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Pesticide residues found on cured tobacco remain a large concern to the allied tobacco industry. To better quantify cured leaf residues, three active ingredients (fluopicolide, indoxacarb, and oxathiapiprolin) were applied to flue-cured tobacco grown...

    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...

    The effect of lower leaf removal and nitrogen application to flue-cured tobacco yield, crop throw, and economic return

    FINCH C.E.(1); VANN M.C.(1); FISHER L.R.(1); INMAN M.D.(1); WELLS 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 & Resource Economics, Raleigh, NC, U.S.A.
    Research was conducted in North Carolina to quantify the impact of the number of lower stalk leaves removed at topping and the subsequent application of four rates of liquid nitrogen. At topping, either 0, 4, or 8 leaves were removed from the lower...
