    Flue-cured tobacco response to sub-lethal rates of glufosinate

    VANN M.C.(1); JORDAN D.L.(1); FISHER L.R.(2)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) NC Agriculture Research Service, North Carolina State University, Raleigh, NC, U.S.A.
    Glufosinate is a broad-spectrum, contact herbicide that is currently applied to genetically engineered row crops that tolerate exposure to the chemical, such as cotton (Gossypium hirsutum), maize (Zea mays), and soybean (Glycine max). Flue-cured...

    Auxin herbicide exposure: comparisons of 2,4-D and dicamba drift to flue-cured tobacco

    VANN M.C.(1); JORDAN D.L.(1); FISHER L.R.(2)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) NC Agriculture Research Service, North Carolina State University, Raleigh, NC, U.S.A.
    Auxin herbicide application has increased in North Carolina due to the commercialization of 2,4-D and dicamba tolerant crops. Flue-cured tobacco is extremely sensitive to both herbicides, yet is commonly grown in close proximity to genetically...

    Efficacy of S-metolachlor based herbicide programs in flue-cured tobacco

    BRADLEY A.; VANN M.C.; CAHOON C.W.; JORDAN D.L.; INMAN M.D.; CLAPP A.M.
    North Carolina Cooperative Extension Service - Edgecombe County, Tarboro, NC USA
    Maximized weed control is critical to the growth and development of flue-cured tobacco. Currently, the PPO-inhibiting herbicide sulfentrazone is the primary control option for Amaranthus, Cyperus, and Ipomea weed species. With the current risk of...

    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...

    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....

    The influence of primary tillage and flue-cured tobacco management on Palmer amaranth populations in a three year crop rotation

    VANN M.C.; FISHER L.R.; JORDAN D.L.; STEWART A.M.; WELLS R.
    North Carolina State University, Raleigh NC USA
    Glyphosate-resistant Palmer amaranth (PA) (Amaranthus palmeri) is a significant issue in agronomic crop production. Research was conducted from 2012 to 2014 and from 2013 to 2015 to quantify the impact of primary tillage, herbicide program, and...
