    Evaluation of cured leaf residues of several common pesticides used in dark air-cured and dark fire-cured tobacco

    BAILEY W.A.; RODGERS J.C.; KEENEY A.B.; RICHMOND M.D.
    University of Kentucky, Research and Education Center, Princeton, KY, U.S.A.
    Pesticide residue trials were conducted from 2011 to 2017 to evaluate cured leaf residues of eight commonly used pesticides registered for use on dark tobacco in the United States. Pesticides tested included azoxystrobin, acephate, lambda-cyhalothrin, and ...

    Chemically topping Burley tobacco

    RICHMOND M.D.(1); PEARCE R.C.(1); BAILEY W.A.(2)
    (1) University of Kentucky, Department of Plant and Soil Sciences, Lexington, KY, U.S.A.; (2) University of Kentucky Research and Education Center, Princeton, KY, U.S.A.
    The act of topping tobacco (Nicotiana tabacum L.) involves the removal of the terminal bud or inflorescence of the tobacco plant. This practice ordinarily is accomplished by manually removing the top of each tobacco plant in an entire field, which is ...

    Evaluation of dark tobacco transplanting intervals following 2,4-D and saflufenacil herbicide applications

    BAILEY W.A.; RODGERS J.C.; KEENEY A.B.; RICHMOND M.D.
    University of Kentucky Research and Education Center, Princeton, KY, U.S.A.
    Marestail (Conyza canadensis L.) has become a major weed problem in dark tobacco production in western Kentucky due to its persistence in conservation tillage production systems and its tolerance to glyphosate herbicide that is typically used in burndown ...

    Preliminary evaluation of curing environment and TSNA accumulation within dark air-cured tobacco

    RICHMOND M.D.; BAILEY W.A.; PEARCE R.C.
    University of Kentucky Research & Education Center, 1205 Hopkinsville Street, Princeton, KY, USA
    Significant variability in cured leaf TSNA content is commonly observed when sampling within dark air-curing barns. This variability may be due to inconsistency in the curing environment within different areas of the barn. A graduate student study was ...

    Dark tobacco response to potassium rate and application timing

    HILL R.A.; BAILEY W.A.; RODGERS J.C.; RICHMOND M.D.
    University of Kentucky, Research & Education Center, 1205 Hopkinsville Street, Princeton, KY 42445, USA
    Field experiments were conducted at the West Farm of Murray State University near Murray, KY in 2012 and 2013 to evaluate dark-fired tobacco response to potassium application rate and timing. Soil test K indexes were in the low range both years, and K 2 O ...

    Preliminary investigation of curing environment and TSNA accumulation within barns in dark air-cured tobacco

    RICHMOND M.D.; BAILEY W.A.; PEARCE R.C.
    University of Kentucky, Research and Education Center, Princeton, KY, U.S.A.
    A graduate student project was initiated in 2012 through support from a CORESTA Study Grant to evaluate correlation between curing microenvironments within designated areas of curing barns and TSNA accumulation. Experiments were conducted in barns near ...

    Preliminary evaluation of cured leaf residues of common pesticides used in dark air-cured and dark fire-cured tobacco

    BAILEY W.A.; RODGERS J.C.; HILL R.A.; RICHMOND M.D.
    University of Kentucky, Research & Education Center, Princeton, KY, U.S.A.
    Pesticide residue data for dark tobacco is limited compared to data available for Burley and flue-cured tobacco. It is also unknown if the curing process (air-curing or fire-curing) affects pesticide residues that remain in the cured leaf. Pesticide ...
