    Alkaloid content of wide tobacco germplasm: the search for high and low nicotine content accumulating genotypes

    MAGAMA F.; SHAMUDZARIRA M.; GARWE D.
    Tobacco Research Board, Harare, Zimbabwe
    Tobacco alkaloids are essential for the flavour, addictiveness, carcinogenicity and utilisation of blended flue-cured tobacco. Although there are strict limits on nicotine and nornicotine content permitted, there is renewed impetus to determine the...

    First report of a pepper potato virus Y isolate affecting tobacco in Zimbabwe

    ZVOBGO G.; MUFUNDA F.; CHINHEYA C.C.; MAGAMA F.; GARWE D.; DIMBI S.
    Tobacco Research Board, Kutsaga, Harare, Zimbabwe
    Potato virus Y (PVY) is an economically important disease, capable of causing 100 % yield losses particularly in late planted tobacco. This is so because the early growth stages coincide with a peak in aphid vector populations. In December 2017,...

    Kutsaga releases a Katambora Rhodes grass variety (G HR 1) for nematode management under tighter rotations

    SHAVA J.G.; MAKUNDE P.T.; MAGAMA F.; SHAMUDZARIRA M.
    Tobacco Research Board, Harare, Zimbabwe
    Although the use of resistant varieties is effective, Katambora Rhodes grass (Chloris gayana) has been used for a long time in rotations not only to suppress nematodes but also to improve the soil structure in tobacco farming systems. This grass was...
