Weeds reduce maize yields by competing for moisture, nutrients, space and light. The Ministry of Agriculture warned that Maize Lethal Necrosis (MLN) had been reported in some districts in eastern Uganda, particularly Busia and Tororo. Since then the disease has been reported in Rwanda and DR. According to researchers who conducted the new study, because maize is a staple crop in Sub-Saharan Africa, the spread of MLN is threatening food security in the region. Maize varieties. MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields. Maize lethal necrosis disease (MLN) was first diagnosed in eastern Africa in the 2010's and is a big threat to their maize-based agri-food systems with estimated losses amounting to US$261 million in Ethiopia and US$198 million in Kenya. The disease, scientists say, can cause up to 100 per cent crop loss. Maize chlorotic dwarf Maize chlorotic dwarf virus (MCDV) 1 .
