    Maximizing the spray droplet to effectively deliver pesticides

    LEGLEITER T.
    University of Kentucky, University of Kentucky Research and Education Center, Princeton, KY, U.S.A.
    Numerous factors influence the efficacy of a pesticide on the intended target pest, including the delivery method of the pesticide to the target pest. Pesticides in the agronomic realm are most often delivered using spray droplets produced by a broadcast ...

    Modification of tobacco chemical constituents by molecular breeding

    LEWIS R.S.; DEWEY R.E.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Tobacco plant chemistry affects consumer perception of derived products and also the potential for health risks associated with their use. Some cured leaf chemical components contribute positively to taste and aroma, while others have negative impacts and ...

    FDA advance notice of proposed rulemaking for nicotine level of combusted cigarettes – feasibility for compliance via tobacco plant genetics?

    HIATT E.
    R.J. Reynolds Tobacco Co., Winston-Salem, NC, U.S.A.
    On March 16, 2018, the U.S. Food and Drug Administration (FDA) published an advance notice of proposed rulemaking (ANPRM) entitled “Tobacco Product Standard for Nicotine Level of Combusted Cigarettes.” The publication of an ANPRM solicits information and ...
