MAIZE LETHAL NECROSIS HISTORY In September 2011, a disease outbreak in Kenya was positively identified as Maize Lethal Necrosis Disease (MLND). First, because of farmers’ frequent complains of maize crop loss, our research team aimed to establish whether the reported disease was MLN and whether there were other possible viruses that co-infect maize, based on symptoms and molecular diagnostics.

It is recommended that farmers should avoid growing maize in consecutive seasons, movement of affected crop debris or materials from one region to another should be stopped to minimize the incidence rates; diversify crops planted and practice crop rotation with non-cereal crops, formulation of extension policy and implement them in all counties to ensure that farmers get necessary information on how to mitigate Maize Lethal Necrosis Disease hence improved maize yield. Intercropping creates a vegetation diversity that can divert or repel the vectors of MLN [. Based on the RT-PCR test, the overall percentage of samples with MCMV was 97%. J Econ Entomol 106, 16-24.
