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

    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...
