1 Maize Lethal Necrosis (MLN) disease: A threat to food security in eastern Africa Francis Mwatuni & B.M. Prasanna MLN Diagnostics and Management Project, CIMMYT, Nairobi, Kenya Presentation to The Trade Africa Feed the Future Regional Conference Arusha – April 12 th 2016

2 MLN in eastern Africa is caused by coinfection of maize plants by MCMV and SCMV

3 What exactly is causing the spread of MLN? Vectors: Presence of aphids and thrips, other insects Environment: Conditions favoring vectors and disease Susceptible Germplasm (seeds)? Virus: Either individual or compound

5 MLN Impact 23% yield loss in Kenya 0.3 million metric tons US $188 million Source: De Groote et al. (2015)

6 We need to tackle the MLN challenge on diverse fronts

10 The purpose of the MLN Phytosanitary CoP: create and ensure a structure that allows the stakeholders to promote the best practices in controlling the spread and impact of MLN in SSA build common capability in MLN-related phytosanitary procedures and practices across the organisations Share knowledge and best practices on MLN diagnostics and management across borders MLN Phytosanitary CoP established in Feb 2016
