    Black shank is a concern for farmers growing tobacco on land infested with Phytophthora nicotianae. The first superior Php gene variety (NC-71) was introduced in 1995. The Php gene confers complete resistance to the wild type of P. nicotianae (race 0), ...

    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Incidence in flue-cured tobacco protected in early-season with thrips exclusion (cages) or thrips suppression (weekly acephate insecticide applications with or without an imidacloprid tray trench treatment). TSW is a serious economic threat to tobacco ...

    Feature selection from near infrared spectra using genetic algorithms for tobacco blend recognition

    FIGUERES G.; DE SOUZA S.; REYNES C.; SABATIER R.; VIDAL B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Near infrared reflectance spectroscopy has proved to be very useful for predicting concentrations of chemical compounds in tobacco, classification or pattern recognition of cigarette blends. The resulting measurement of a sample is a whole reflectance ...

    How representative of the human smoking behaviour would be the new alternative smoking regimes? A first attempt of assessment

    MARCHAND V.; TESSIER C.; DUMERY B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The ISO or FTC smoking conditions (35 mL- 2 s puffs, 1 puff per minute) have been more and more criticized during the last decade, especially because they would not reflect the human smoking behaviour. Their main objective was not to predict the exact ...

    A mixture experimental design with six variables and the effects on smoke components:1 - Presentation of this experimental design and of some initial results on physical characteristics of cigarettes and blends

    VIDAL B.; FIGUERES G.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The objective of this paper is to examine the effects of six tobacco components on the chemical and physical characteristics of blends and cigarettes and particularly on the mainstream smoke yields. First of all, we will develop the philosophy of this ...
