SUMMARY: Maize lethal necrosis disease (MLND) is a new viral disease for Africa. Domestic regulation can be put in place to prevent the movement of maize products from affected areas to disease-free regions. MAIZE LETHAL NECROSIS HISTORY In September 2011, a disease outbreak in Kenya was positively identified as Maize Lethal Necrosis Disease (MLND). Maize lethal necrosis (MLN) is a new, devastating disease in East Africa that leads to severe production losses and, in many cases, complete crop failure. In sub-Saharan Africa, maize is a staple food and key determinant of food security for smallholder farming communities. MLND . Infected plants die prematurely. Efforts in managing the maize lethal necrosis disease have contributed to reducing seed production losses, an expert has said. The leaves begin to dry from the margins and progressing toward the midrib. A serious disease outbreak in Kenya, later diagnosed as maize lethal necrosis, was first reported in September 2011 in the Longisa division of the Bomet district. Maize lethal necrosis disease (MLND) negatively affects maize crops and their seeds and is threatening food and economic security in East and Central Africa. Since then the disease has been reported in Rwanda and DR . The disease prevents the plants from growing tall, causes yellowing and death of the leaves, and stops the ears from growing and setting seeds. Symptoms similar to MLN were reported in … Prevention. Leaves show a yellow-green mottled pattern, often parallel to the veins. The Maize Lethal Necrosis Disease (MLND) is a result of a combination of two viruses, the Maize Chlorotic Mottle Virus (MCMoV) and any of the cereal viruses in the Potyviridae group, like the Sugarcane Mosaic Virus (SCMV), Wheat Streak Mosaic Virus (WSMV) or Maize Dwarf Mosaic Virus (MDMV). Jonathan and Harrison are victims of the Maize Lethal Necrosis (MLN) devastating farmers across East Africa. Seed Inspectors can check for Maize lethal necrosis disease (MLND) in seed farms. Maize Lethal Necrosis Disease . In severe infections, the whole plants withers and dead hearts are visible inside the stems. In a Nutshell. In September 2011, a serious disease outbreak, later diagnosed as maize lethal necrosis … Disease Symptoms of Maize Lethal Necrosis (MLN) Early MLN Symptoms Mosaic and mottling Mild mosaic and mottling Shortened internodes; Severe chlorotic mottle Severe chlorosis and leaf necrosis ‘Dead Heart’ symptoms Necrosis starting from the leaf margin, coupled with mottling Premature drying of the husks Poor or no grain filling By 2012, symptoms consistent with maize lethal necrosis were observed in a number of districts in the Central, Nyanza, Western and Rift Valley provinces of Kenya. A plant health inspectorate organization can test for Maize chlorotic mottle virus (MCMV) in all seed coming into the country including the material for breeding. Virus. USE PLANTIX NOW! According to Dr Ann Wangai, a Chief research scientist specialized in plant virology at KALRO, the disease first reported in Bomet in 2012, is caused by a combination of the Sugarcane Mosaic Virus and Maize Chlorotic Mortal Virus. The double infection of the two viruses gives rise to what This project researched solutions to minimize or eliminate the risks and effects of the disease in the region. It has caused great concern because plants are killed and little or no grain is produced. The main thrust of the current management strategy is to prevent the introduction of the disease through sound surveillance and early destruction of diseased plants.
