    Characterisation of root-knot nematode (Meloidogyne javanica) resistance mechanism in tobacco

    MAKUNDE P.T.; MAHERE T.S.; DIMBI S.; GARWE D.
    Tobacco Research Board, Harare, Zimbabwe
    Resistance to root-knot nematode (Meloidogyne spp) has been identified, incorporated, and deployed in Kutsaga commercial cultivars of tobacco, Nicotiana tabacum. These cultivars have varying resistance levels to root-knot nematode. The classification...

    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...

    Pythium myriotylum, the dominant Pythium species associated with root rot of tobacco seedlings produced using the float tray system in Zimbabwe

    MUFUNDA F.; MUZHINJI N.; SIGOBODHLA T.; KASHANGURA C.
    Tobacco Research Board, Harare, Zimbabwe
    Pythium root rot caused by the oomycete Pythium species is the most serious disease affecting tobacco seedlings produced under the hydroponic float tray system in Zimbabwe. Currently, knowledge of the occurrence and genetic diversity of the Pythium...

    Zimbabwean tobacco growers spoilt for choice: TRB continually screens and recommends new greener agrochemicals

    GARWE D.; MASUKWEDZA R.; DIMBI S.
    Tobacco Research Board, Harare, Zimbabwe
    Due to their detrimental effects on the environment, flora and fauna, many agrochemicals have been banned, phased-out, or their use heavily restricted in recent years. For example, the effective but broad spectrum and purple label crop protection...

    Phenotypic plasticity in flue-cured tobacco roots: a strategy for improved drought resilience breeding

    SHAMUDZARIRA M.; SHAVA J.G.; MAWIRE B.; MAGAMA F.; DIMBI S.
    Tobacco Research Board, Harare, Zimbabwe
    Drought is becoming more prevalent in Zimbabwe where it is affecting yield and sustainable tobacco production. Notably, there has also been an increase in the number of farmers growing tobacco in marginal and drought prone regions. Different methods...

    A breakthrough in breeding for PVY resistance in elite flue-cured tobacco parentals in Zimbabwe

    MAGAMA F.; KASHANGURA C.; MUFUNDA F.; SIGOBODHLA T.; DIMBI S.
    Tobacco Research Board, Harare, Zimbabwe
    Potato virus Y (PVY) is one of the more economically important viruses of tobacco (Nicotiana tabacum L.) in Zimbabwe. Previously, this debilitating disease was controlled by cultural practices which are no longer being strictly adhered to resulting...
