  • Stakeholders reveal significance of seed testing

    IITA - Control measures against pests and diseases dominated discussions at a recent workshop in IITA, Ibadan, held 27-28 September. Stakeholders explored opportunities to interact, exchange ideas, and impart knowledge about major pests and pathogens of maize, risks to maize seed health, and seed-borne pathogens. Read More

  • Second screening cycle for deadly MLN virus set to begin in Kenya

    The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin its second screening cycle of 2017 at the end of October, interested organizations from both the private and public sectors are invited to send maize germplasm for screening. Read more.

  • New online portal offers information to curb maize lethal necrosis in Africa

    The new maize lethal necrosis (MLN) online portal provides up-to-date information and surveillance tools to help researchers control and stop the spread of the deadly disease that has ravaged maize farming in eastern Africa countries of Ethiopia, Kenya, Rwanda, Tanzania and Uganda. The portal details the spread of MLN, where the disease has been managed and controlled, and how to identify it in the field. Read More.

  • New Publication: Fighting a destructive crop disease with mathematics

    From Phys.org - An international team of researchers has used mathematical modelling to understand new ways of combating maize lethal necrosis, an emerging disease that poses a serious threat to food security in sub-Saharan Africa. Maize lethal necrosis (MLN) arises from the interaction of two viruses: maize chlorotic mottle virus (MSMV) and a virus from a group named potyviruses, often sugarcane mosaic virus (SCMV). But traditional modelling has focused on understanding just one virus at a time. Read more

  • Maize lethal necrosis quarantine facility opens avenues for introducing novel maize germplasm in southern Africa

    HARARE, Zimbabwe – The maize lethal necrosis (MLN) quarantine facility in southern Africa was officially opened in Zimbabwe on April 20, 2017 to enable safe introduction and exchange of novel maize germplasm from CIMMYT to partners in southern Africa. Read More

  • New Publication: An Atypical Thioredoxin Imparts Early Resistance to Sugarcane Mosaic Virus in Maize

    Sugarcane mosaic virus (SCMV) causes substantial losses of grain yield and forage biomass in susceptible maize worldwide. A major quantitative trait locus, Scmv1, has been identified to impart strong resistance to SCMV at the early infection stage. Read more
