    Agronomic and qualitative performance of some experimental Burley hybrids in Malawi

    CHAMANGO A.M.Z.; SIBANDE L.A.G.O.; MATEWELE M.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Malawi mainly depends on tobacco for forex generation, with Burley as a major contributor. However, the country has a limited choice of high yielding and disease resistant varieties against a plethora of disease constraints, particularly root-knot ...

    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 ...

    Developing flue-cured tobacco hybrids with combined resistance to granville wilt and root-knot nematodes and angular leaf spot in Malawi

    SIBANDE L.A.G.O.; CHAMANGO A.M.Z.; GOMONDA R.W.J.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Flue-cured tobacco production in Malawi is constrained by both soil-borne (root-knot nematodes and Granville wilt) and aerial borne (angular leaf spot and alternaria brown spot) diseases. To address these multiple challenges, a breeding programme was ...

    Breeding for disease resistant dark-fire-cured tobacco in Malawi

    CHAMANGO A.M.Z.; GOMONDA R.W.J.; MAINJENI C.E.D.; MSANGOSOKO K.R.; KHUMBANYIWA A.G.; KASANGA T.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Dark fire-cured tobacco (DFC) is the third most important tobacco type grown in Malawi after Burley and flue-cured. With Malawi Western, MW 86-57 and AWL 28 as the leading approved DFC varieties for production in Malawi, the local and regional ...

    Scout based application and integration of nematode resistant cultivars: an IPM strategy for reducing pesticide use in tobacco production in Malawi

    MSANGOSOKO K.R.; MAINJENI C.E.D.; GOMONDA R.W.J.; CHAMANGO A.M.Z.
    Agricultural Research and Extension Trust (ARET), Lilongwe, Malawi
    Tobacco production in Malawi faces serious pest problems such as the tobacco aphid (M. persicae) and root-knot nematodes (Meloidogyne spp.). A considerable amount of pesticides are used by growers to protect tobacco from yield and quality losses resulting ...
