It is now scientifically double-checked. In Uganda, the Maize Lethal Necrosis Virus (MLN) is prevalent in most farmers’ fields in the districts of Tororo, Mbale, Sironko and Busia. According to survey findings published in the African Journal of Agricultural Research, the disease can attack at any stage of crop growth, two weeks after planting leading to average yield losses of up to 50.5% or US$ 332 per hectare. First reported in Uganda in 2013, information about the prevalence, yield loss, mitigation measures and socio-economic effects of MLN is still scanty.
Survey findings of a study conducted by NARO and ASARECA involving 300 respondents in seven districts of Eastern Uganda on the status of the disease, recommends intensification of MLN sensitization to inform farmers on management practices such as crop rotation, good sanitation practices, and use of chemical sprays to control MLN. The study, however, indicates that expediting the breeding process for the development of MLN resistant or tolerant varieties is the most viable option to bring a lasting solution to the disease.
