    Bacterial wilt (Ralstonia solanacearum) resistant flue-cured hybrids - current Malawi situation

    SIBANDE L.A.G.O.; CHAMANGO A.M.Z.; MATEWERE M.; KHUMBANYIWA A.G.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    In Malawi, flue-cured tobacco production is negatively affected by both aerial and soil borne diseases. Bacterial wilt (Ralstonia solanacearum) is one of the major soil borne diseases that attack the crop, reducing cured leaf yield and quality. Currently ...

    Comparing direct and indirect assessments of perceptions of reduced risk for a modified-risk tobacco product

    SHIFFMAN S.(1); CURTIN G.(2)
    (1) Pinney Associates, Pittsburgh, PA, U.S.A.; (2) RAI Services Company, Winston-Salem, NC, U.S.A.
    Manufacturers seeking to make claims about modified-risk tobacco products (MRTPs) must assess consumers' perceptions of absolute and relative risks for these products. We cross-validate data from two methods: (a) indirect assessments based on the ...

    (1) RAI Services Company, Winston-Salem, NC, USA; (2) PinneyAssociates, Inc., Pittsburgh, PA, USA
    Smokers can benefit from switching to less harmful tobacco products, which requires knowledge of relative product risk. However, publicly shared information often emphasizes absolute rather than relative risks. To understand smokers’ perceptions of ...
