    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 ...

    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. ...

    Spinosad and cyantraniliprole residues in flue-cured tobacco

    INMAN M.D.; VANN M.C.; SEAGROVES R.W.; FISHER L.R.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, U.S.A.
    From 2013 to 2015 research was conducted to establish the maximum expected pesticide residue on cured tobacco that would result from a maximum labeled application rate and minimum pre-harvest interval of specific active ingredients. Residues of two ...

    Addressing calcium deficiency in flue-cured tobacco

    VANN M.C.; FISHER L.R.; INMAN M.D.; WHALEY W.T.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, U.S.A.
    With the exception of potassium and nitrogen, calcium (Ca) accumulation by flue-cured tobacco is greater than all other nutrients. Despite such high demand, Ca application is not recommended to well-limed soils. In 2015, Ca deficient tobacco was visually ...
