  • How do we sustainably manage transboundary diseases and crop pests?

    CGIAR webinar examined the technological, sustainability and social implications of integrated approaches.   By Madeline Dahm March 25, 2021   In our hyper-connected world, it should come as no surprise that recent years have shown a major uptick in the spread of transboundary pests and diseases. Integrated approaches have been effective in sustainably managing these border-jumping threats to farmers’ livelihoods and food security. But a truly integrated approach accounts for not just the “cure,” but also how it can be sustainably incorporated into the agri-food system and social landscape.  For example, how do we know if the farmers who adopt disease- and pest-resistant seed will be able to derive better incomes? And how do we ensure that incentives are aligning with community norms and values to enable better adoption of integrated disease or pest management approaches? Experts from across the CGIAR research system and its partners weighed in on this topic in the recent webinar on Integrated Pest and Disease ...

  • Second screening cycle for deadly MLN virus set to begin in Kenya during April 2021

    By Dr. Suresh, L.M.:  The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin the second interval of its phenotyping (screening/ indexing) cycle of 2021 at the beginning of April 2021. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening. In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture. MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields. CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing ...

  • Screening cycle for deadly MLN virus set to begin in Kenya during January 2021

    By Dr. Suresh, L.M.: The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin its phenotyping (screening/ indexing) cycle of 2021 at the beginning of January 2021 and in other four intervals, interested organizations from both the private and public sectors are invited to send maize germplasm for screening. In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.

  • Maize lethal necrosis (MLN): Efforts toward containing the spread and impact of a devastating transboundary disease in sub-Saharan Africa

    Highlights Maize lethal necrosis (MLN) emerged as a serious threat to maize production and livelihoods of smallholders in eastern Africa since 2011.        An intensive multi-disciplinary and multi-institutional strategy is being implemented to curb the spread of MLN in sub-Saharan Africa, and mitigate the impact of the disease. Intensive germplasm screening led to identification of MLN-resistant sources, and fast-tracked development and commercial release of 19 MLN-tolerant/resistant hybrids in eastern Africa. Marker-assisted breeding led to successful conversion of 52 elite but MLN-susceptible inbred lines into MLN-resistant versions. MLN/MCMV diagnostic protocols have been optimized, and personnel from relevant public and private sector institutions trained on MLN diagnostics, monitoring and surveillance.  Abstract Maize lethal necrosis (MLN), a complex viral disease, emerged as a serious threat to maize production and the livelihoods of smallholders in eastern Africa since 2011, primarily due to the introduction of maize chlorotic mottle virus (MCMV). The International Maize and Wheat Improvement Center (CIMMYT), ...

  • 2020 screening cycle for deadly MLN virus in Kenya – November Planting
