Farmers’ Critical Role in Fight to Prevent Spread of MLN

Examining for MLNIn the fight to prevent and control the spread of maize lethal necrosis (MLN) across Eastern Africa, the support and cooperation of everyone involved in maize production is crucial—especially farmers. This was the main focus of CIMMYT’s 4th stakeholders meeting, held 15 October in Kenya, which brought together 56 local farmers as well as community leaders, administrators, government extension officers, KALRO and CIMMYT staff. The meeting was held to share new information on MLN and agree on the best methods to control the incidence and spread of the disease.

Maize Lethal Necrosis: Building a comprehensive response

In September 2011, reports came of a devastating new maize disease in the Southern Rift Valley of Kenya. The symptoms were described as mottling of the leaves, small cobs with few grains, and necrosis of young leaves leading to “dead heart” and eventually plant death. It was common for affected fields to show 100 percent infection rates, meaning that some farmers faced losing the entire crop.

MLN is a disease caused by a combination of maize chlorotic mottle virus, and any other potyvirusBy October 2012, a study team sent by CIMMYT and the Kenya Agricultural and Livestock Research Organization (KALRO) confirmed the disease to be maize lethal necrosis (MLN).

MLN Diagnostics and Management in Africa through Multi-Institutional Synergies

MLN brochureMaize Lethal Necrosis (MLN) disease has continued to wreak havoc on maize production in East Africa since it was first reported in Kenya in 2011, and since then reported in the Democratic Republic of the Congo, Ethiopia, Rwanda, Tanzania, South Sudan and Uganda. The disease, caused by a combination of the Maize Chlorotic Mottle Virus (MCMV) and Sugarcane Mosaic Virus (SCMV), causes irreversible damage that kills maize plants before they can grow and yield grain.
