The disease has caused major losses to maize crops of up to 90%, resulted in an estimated grain loss of 126,000 tons valued at $52 million in Kenya alone,  and decreased food security. This emerging threat is now endemic in much of East Africa,  and has been reported  and confirmed in DR Congo, Ethiopia, Kenya, Rw anda, South Sudan, Tanzania,  and Ug anda.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Speaking at the opening ceremony, <a href=\"https:\/\/iita.org\/fr\/iita-staff\/asiedu-robert\/\" target=\"_blank\" rel=\"noopener\">Robert Asiedu<\/a>, Director, Research for Development, IITA-West Africa, represented by <a href=\"https:\/\/iita.org\/fr\/iita-staff\/abberton-michael\/\" target=\"_blank\" rel=\"noopener\">Michael Abberton<\/a>, IITA Deputy Director, Research for Development, West Africa,  and Head, IITA Genetic Resources Center, commended all the participants for their efforts towards making the meeting a huge success,  and urged them to seize the opportunity to integrate, educate,  and exchange ideas on strategies to fight  and prevent the menace.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, <a href=\"https:\/\/iita.org\/fr\/iita-staff\/menkir-abebe\/\" target=\"_blank\" rel=\"noopener\">Abebe Menkir<\/a>, Leader, IITA Maize Program, applauded the participants, as he said: \u201cI welcome you all to this very important meeting; MLN has been a significant challenge affecting maize production. I am looking forward to seeing positive contributions  and a solid approach towards preventing the further spread of MLN in Eastern Africa.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><figure id=\"attachment_14288\" aria-describedby=\"caption-attachment-14288\" style=\"width: 300px\" class=\"wp-caption alignright\"><a href=\"http:\/\/www.iita.org\/wp-content\/uploads\/2017\/10\/1024_DSC_8503.jpg\"><img decoding=\"async\" class=\"size-medium wp-image-14288\" src=\"https:\/\/iita.org\/wp-content\/uploads\/2026\/06\/1024_DSC_8503-300x200.jpg\" alt=\"Picture of Monica Mezzalama of CIMMYT (right) with one of the working groups during the MLN meeting in IITA.\" width=\"300\" height=\"200\" \/><\/a><figcaption id=\"caption-attachment-14288\" class=\"wp-caption-text\">Monica Mezzalama of CIMMYT (right) with one of the working groups during the MLN meeting in IITA.<\/figcaption><\/figure><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/iita.org\/fr\/iita-staff\/kumar-lava\/\" target=\"_blank\" rel=\"noopener\">Lava Kumar<\/a>, Head, IITA Germplasm Health Unit  and focal point for the Conference, emphasized the importance of collaborative effort, partnership,  and commitment in developing a prevention  and disease management strategy. Director of CIMMYT\u2019s Global Maize Program, <a href=\"http:\/\/www.cimmyt.org\/essential_grid\/maruthi-prasanna-boddupalli\/\" target=\"_blank\" rel=\"noopener\">Boddupalli M. Prasanna<\/a>, was of the view that all stakeholders should prepare to learn, raise awareness,  and replicate all the knowledge acquired to achieve a substantial result.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During the plenary session, there was a discussion on strategies for MLN prevention  and preparedness. Stakeholders deliberated on ways to identify  and prioritize strategy, needs, partnerships, capacity development,  and funding for improving phytosanitary policies, prevention  and emergency control action in the areas of quarantine monitoring, safe production of maize seed,  and preemptive breeding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The disease is a result of infection by MCMV,  and cereal viruses in the Potyviridae group, especially Sugarcane Mosaic Virus (SCMV), which causes an estimated 30% to total crop loss in farmers\u2019 fields depending on the severity of the incidence, posing a threat\u00a0to regional trade. Hygienic practices, crop rotation, effective surveillance, monitoring systems,  and use of pesticides for insect vector control, are some of the methods that could be used for MLN\/MCMV control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In concluding the meeting, the stakeholders embarked on a tour of the <a
