Efforts in managing the maize lethal necrosis disease have contributed to reducing seed production losses, an expert has said. Prevention. Infected plants die prematurely. 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).

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 main thrust of the current management strategy is to prevent the introduction of the disease through sound surveillance and early destruction of diseased plants. Maize Lethal Necrosis Disease .
