  • Visit of partners, farmers and key stakeholders to MLN screening facility, Naivasha, Kenya

    a). County extension officers and lead farmers visit the regional MLN screening unit at Naivasha: Fourty county extension officers and lead farmers from Uasin Gishu county and Tana River county and 5 KALRO facilitators visited the MLN screening unit at Naivasha on 27th October 2021. They were taken round by Mr. Wilson Njenga and Mr. James Matunde of KALRO-CIMMYT, MLN Screening facility. They reckoned that they had seen MLN in the maize fields, but they were not aware that a lot of work was being done to manage the disease. They hailed the selfless efforts CIMMYT was putting to help the farmers. After seeing the two viruses, Maize Chlorotic Mottle Virus and Sugarcane Mosaic Virus and the MLN affected plants after artificial inoculation in the field they highly appreciated the work. They were impressed by the good partnerships between CIMMYT, KALRO, other NARS and seed companies and they noted that ...

  • MAIZE PARTNERS ANNOUNCE A NEW MANUAL FOR EFFECTIVELY MANAGING MAIZE LETHAL NECROSIS (MLN) DISEASE

    Dr. Suresh,L.M. (November, 2021): For a decade, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been at the forefront of a multidisciplinary and multi-institutional effort to contain and effectively manage maize lethal necrosis (MLN) disease in Africa. When the disease was first reported in Kenya 2011 it spread panic among stakeholders. Scientists soon realized that almost all commercial maize varieties in Africa were susceptible. What followed was a superlative effort coordinated by the CGIAR Research Program on Maize (MAIZE) to mobilize “stakeholders, resources and knowledge” that was recently highlighted in an external review of program. The publication of Maize Lethal Necrosis (MLN): A Technical Manual for Disease Management builds on the partnerships and expertise accrued over the course of this effort to provide a comprehensive “guide on best practices and protocols for sustainable management of the MLN.” The manual is relevant to stakeholders in countries where MLN is already present, and also aims to offer technical ...

  • Third screening cycle for deadly MLN virus set to begin in Kenya during October 2021

    By Dr. Suresh, L.M. (September, 2021) :  The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin the third interval of its phenotyping (screening/ indexing) cycle of 2021 at the beginning of October 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 ...

  • 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
