    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...

    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....
