    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 ...
